BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention is directed to an apparatus and its method of use in intra-abdominally moving a first internal organ to a position away from a second internal organ where the apparatus holds the first internal organ in the position without further manual input. More specifically, the present invention is directed to an apparatus that is inserted through the abdominal wall and into the abdominal cavity, and the method of using the apparatus in the abdominal cavity to move a human liver to a position away from a human stomach where the apparatus holds the liver in the position without further manual input, thereby providing surgical access to the stomach.
2. Description of the Related Art
In laparoscopic surgical procedures, it is often necessary to make incisions through the abdominal wall for the sole purpose of providing access to the abdominal cavity for surgical graspers or other similar types of retracting instruments that are used to move one internal organ to a position away from a second internal organ to gain surgical access to the second internal organ. The incisions made for the surgical graspers or similar retracting instruments are in addition to the incisions made in the abdominal wall for the surgical instruments used in performing the surgical procedure on the second organ.
Furthermore, it is often necessary that an additional surgeon or surgical assistant be present solely for the purpose of manipulating the surgical graspers or other similar retracting instruments in moving the first internal organ to a position away from the second internal organ, and then manually holding the first internal organ in the position during the surgical procedure performed on the second internal organ.
The need for the additional surgical personnel to manipulate and hold the surgical graspers or other similar retracting instruments during the surgical procedure increases the costs of surgery. In addition, the additional incisions in the abdominal wall required for the surgical graspers or other similar retracting instruments often results in additional discomfort to the patient following surgery and additional scarring.
What is needed to overcome these disadvantages associated with the above-described type of laparoscopic surgical procedure is an apparatus that can be operated to intra-abdominally move a first internal organ to a position away from a second internal organ and then hold the first internal organ in the position without requiring additional manual input other than that provided by the surgeon and without requiring additional abdominal incisions other than those required for the surgery.
SUMMARY OF THE INVENTIONThe present invention overcomes the above-described shortcomings of laparoscopic surgical procedures by providing an apparatus that can be inserted into the abdominal cavity through the same incision to be used in a laparoscopic surgery procedure, and the method of using the apparatus to move or retract a first internal organ, for example the liver, away from a second internal organ, for example the stomach, and then hold the first internal organ in the retracted position providing surgical access to the second internal organ without requiring further manual input.
The apparatus is constructed of component parts that are often used in laparoscopic as well as other types of surgical procedures. The component parts will be described herein using their common understood names and their functions, without going into details of the particular constructions of the component parts.
The basic construction of the apparatus of the invention includes a length of cord. The cord could be comprised of a first cord segment having a flexible length with opposite first and second ends, and a second cord segment having a flexible length with opposite first and second ends. The cord segments could be provided by lengths of suture, lengths of tubing such as IV tubing, lengths of umbilical tape or elastic strips, or other equivalent cord constructions. The first and second cord segments could be separate cord segments that are attached together, or could be two cord segments of a single continuous length of cord.
In one embodiment of the apparatus, first, second, and third separate tissue connectors are attached to the first and second cord segments. The tissue connectors can be any type of known tissue connector that can be manually manipulated to connect to body tissue, and then manually manipulated to be removed from the body tissue without leaving any significant damage to the body tissue. In addition, the tissue connectors can be biocompatible tissue connectors that are designed to be left in the abdominal cavity after the surgery. Some examples of such tissue connectors include suture needles, ‘T’ bars, graspers, barbed needles, hooks, clasps, rivet assemblies, or any other equivalent type of connector. The first and third tissue connectors are attached to the opposite ends of the first cord segment and the second and third tissue connectors are attached to the opposite ends of the second cord segment. This positions the first and second tissue connectors at the opposite ends of the combined lengths of the first and second cord segments, and positions the third tissue connector at an intermediate position of the combined lengths of the first and second cord segments.
In the use of the apparatus according to the method of the invention, the apparatus is first manually passed through the abdominal wall, for example through an incision or a cannula in the abdominal wall, and is positioned in the abdominal cavity in the area of the first and second internal organs. The third tissue connector is then manually connected to tissue adjacent the first internal organ. This positions the ends of the first and second cord segments connected to the third tissue connector between the first and second internal organs and on an opposite side of the first internal organ from the abdominal wall. The first tissue connector attached to the opposite end of the first cord segment from the third tissue connector is manually moved causing the length of the first cord segment to move and engage across the first internal organ and to move the first internal organ toward the position away from the second internal organ. The first tissue connector is then manually connected to the abdominal wall.
The second tissue connector attached to the opposite end of the second cord segment from the third tissue connector is then manually moved causing the second cord segment to move and engage across the first internal organ and move the first internal organ toward the position away from the second internal organ. The second tissue connector is then manually connected to the abdominal wall.
In the above matter, the first and second cord segments engaging across the first internal organ hold the first internal organ at the position away from the second internal organ without further manual input. This provides surgical access to the second internal organ.
In a further embodiment of the apparatus of the invention, the apparatus is comprised of a cord having a continuous flexible length with opposite first and second ends. A needle is attached to one end of the length of cord and a knot is formed in the opposite end of the length of cord.
According to the method of use of this embodiment of the apparatus, the apparatus is first positioned inside the abdominal cavity in the same manner as the previously-described embodiment. The knotted end of the length of cord is then connected to tissue adjacent the first internal organ by first passing the needle through the tissue and then manually pulling the length of cord through the tissue. This attaches the knotted end of the cord to the tissue between the first and second internal organs.
The needle is then passed through the inter-abdominal wall and manually moved back into the abdominal cavity, causing a first segment of the length of cord to engage across the first internal organ and move the first internal organ toward the position away from the second internal organ.
The needle is then again inserted through the inter-abdominal wall at a location spaced from the first insertion of the needle through the inter-abdominal wall, and the needle and length of cord are pulled manually into the abdominal cavity.
The needle and the end of the length of cord attached to the needle are then passed through the knot formed at the opposite end of the length of cord and pulled tight, causing a second segment of the length of cord to engage across and move the first internal organ toward the position away from a second internal organ. A knot is then tied between the opposite ends of the length of cord and the portion of the cord extending from the knot to the needle is cut and removed with the needle from the abdominal cavity. The length of cord left in the abdominal cavity forms a triangular loop with first and second cord segments that engage across and hold the first internal organ in the position away from the second internal organ without manual input. In this manner, surgical access is provided to the second internal organ without manual input.
A still further embodiment of the apparatus of the invention is comprised of a cord having a continuous flexible length with opposite first and second ends, and a tissue connector assembly with a releasable one-way cord lock connected to an intermediate portion of the cord.
The tissue connector assembly has a base formed as a cylindrical housing. The base housing has a length with opposite first and second ends and a hollow interior bore extending through the housing. A rod is attached to the base and is positioned in the interior bore adjacent the housing second end.
A first tissue connector is provided on the base and extends from the base first end. As in previous embodiments, the tissue connector can be any known type of tissue connector.
The intermediate portion of the cord length is attached to the base by being wrapped around the rod in the base housing. A first portion or first percentage of the cord length extends from the cord intermediate portion and from the base second end to the cord first end. A second portion or second percentage of the cord length extends from the cord intermediate portion and from the base second end to the cord second end.
A releasable one-way lock is mounted in the interior bore of the base for movement of the lock between first and second positions of the lock relative to the base. The lock is biased by a spring toward the first position. In the first position of the lock relative to the base, the lock engages with the intermediate portion of the cord wrapped around the rod and allows the cord first portion to be pulled from the base second end to thereby increase a length or percentage of the cord first portion while decreasing a length or percentage of the cord second portion, but the lock prevents the cord second portion from being pulled from the base second end. In the second position of the lock relative to the base the lock is disengaged from the cord and allows the cord second portion to be pulled from the base second end to thereby increase the length or percentage of the cord second portion while decreasing the length or percentage of the cord first portion.
A second tissue connector is provided at the cord second end. Again, the second tissue connector can be any known type of tissue connector. A percentage of the cord length extends between the first and second tissue connectors. This percentage of the cord length is adjustable.
There is an actuator on the base that is operatively connected to the lock. The actuator is movable between first and second positions of the actuator relative to the base. When the actuator is moved from the first position to its second position it causes the lock to move from its first position to its second position and releases the one way lock. The spring bias of the lock also biases the actuator from its second position toward its first position.
In the use of this embodiment of the apparatus according to the method of the invention, the apparatus is first positioned inside the abdominal cavity in the same manner as the previously described embodiments.
With the apparatus positioned in the abdominal cavity, the second tissue connector at the cord's second end is connected to tissue adjacent to the first internal organ or to the organ itself. The tissue connector assembly with the releasable one-way cord lock is then grasped at the actuator and moved toward the abdominal wall, causing the cord second portion to be extended across the first internal organ. When the cord second portion is pulled tight continued movement of the tissue connector assembly causes the actuator to move to its second position. This releases the lock and allows the cord second portion to be pulled from the base second end increasing the length or percentage of the cord second portion and decreasing the length or percentage of the cord first portion. The first tissue connector is then connected to the abdominal wall and the actuator is released, causing the actuator and the lock to move to their first position due to the bias of the spring. The cord first portion is then grasped and pulled from the second end of the base. This in turn causes the length or percentage of the cord second portion to decrease. As the cord first portion is pulled from the base second end the length or percentage of the cord second portion continues to decrease and causes the cord second portion to engage across the first internal organ and move the first internal organ toward the position away from the second internal organ. With the releasable one-way lock biased to the first position relative to the base, the cord second portion cannot be pulled from the base.
In the above manner, the shortened length of the cord second portion extending between the first tissue connector connected to the abdominal wall and the second tissue connector connected to the body tissue adjacent the first internal organ engages across the first internal organ and holds the first internal organ at the position away from the second internal organ without further manual input. This provides surgical access to the second internal organ.
When it is desired to remove the apparatus of the invention, the actuator is grasped and moved from its first position to its second position relative to the apparatus base. This in turn causes the lock to move from its first position to its second position releasing the lock, and allows the cord second portion to be pulled from the base second end increasing the length or percentage of the cord second portion while decreasing the length or percentage of the cord first portion. This allows the cord second portion to disengage from the first internal organ and produces a sufficient length of the cord second portion to allow the first tissue connector to be removed from the abdominal wall and the second tissue connector at the cord second end to be removed from the body tissue adjacent the first internal organ or from the organ. The apparatus then can be removed from the abdominal cavity.
As described above, the embodiments of the apparatus of the invention and their methods of use enable intra-abdominally moving a first internal organ to a position away from a second internal organ where each of the embodiments of the apparatus holds the first internal organ in the position without manual input.
Further features of the apparatus of the invention and its method of use are set forth in the following detailed description of the apparatus and method and are shown in the drawing figures.
The basic construction of the apparatus 12 of the invention includes a length of cord. In the example of
The cord segments 14, 22 could be provided by lengths of suture, lengths of tubing such as IV tubing, lengths of umbilical tape or elastic strips, or other equivalent cord constructions. The tubing or tape configurations of the cord segments have the advantage of being less likely to dig into or cut into the first internal organ in use of the apparatus to be described. The first 14 and second 22 cord segments could be separate cord segments that are attached directly together, or separate cord segments that are attached by way of a further cord segment 28 or some other component part of the apparatus, or two cord segments of a single continuous length of cord such as the two cord segments 14a, 22a shown in
First 32, second 34, and third 36 separate tissue connectors are attached to the first 14 and second 22 cord segments. The tissue connectors 32, 34, 36 can be any type of known tissue connector that can be manually manipulated to connect to body tissue, and then manually manipulated to be removed from the body tissue 12 without leaving any significant damage to the body tissue. In addition, the tissue connectors 32, 34, 36 could be biocompatible tissue connectors that are designed to be left in the abdominal cavity after the surgical procedure is completed. Some examples of tissue connectors include suture needles, ‘T’ bars, surgical graspers, barbed needles, hooks, clasps, rivet assemblies, or any other equivalent type of connector. In the apparatus of the invention, it is not necessary that all three tissue connectors 32, 34, 36 be the same type of tissue connector. Because various different types of tissue connectors may be employed with the apparatus 12 of the invention, the three tissue connectors 32,34,36 of the apparatus 12 are represented schematically in the drawing figures. The first 32 and third 36 tissue connectors are attached to the opposite ends of the first cord segment 14. The third tissue connector 36 is also attached to one end of the second cord segment 22, with the second tissue connector 34 being connected to the opposite end of the second cord segment 22. This positions the first 32 and second 34 tissue connectors at the opposite ends of the combined lengths of the first 14 and second 22 cord segments, and positions the third tissue connector 36 at an intermediate position of the combined length of the first 14 and second 22 cord segments. In
The third tissue connector 36 of the apparatus is then manually connected to tissue 52 adjacent the first internal organ 48 and between the first 48 and second 50 internal organs. In the example shown in
The first tissue connector 32 attached to the opposite end 16 of the first cord segment 14 from the third tissue connector 36 is then manually moved causing the length of the first cord segment 14 to move and engage across the first internal organ 48. Continued movement of the first tissue connector 32 causes the first cord segment 14 engaging across the first internal organ 48 to move the first internal organ toward a position away from the second internal organ 50. The first tissue connector 32 is then manually connected to the inner abdominal wall 42.
The second tissue connector 34 attached to the opposite end 24 of the second cord segment 22 from the third tissue connector 36 is then manually moved causing the second cord segment 22 to move and engage across the first internal organ 48. Continued movement of the second tissue connector 34 causes the second cord segment 22 engaging across the first internal organ 48 to move the first internal organ 48 toward the position away from the second internal organ 50. The second tissue connector 34 is then manually connected to the inner abdominal wall 42.
With the apparatus 12 connected between the tissue 52 and the inner abdominal wall 42 in the manner discussed above, the first cord segment 14 and the second cord segment 22 engage across the first internal organ 48 and hold the first internal organ 48 at the position away from the second internal organ 50 without further manual input. This provides surgical access to the second internal organ 50. Without requiring manual holding or restraining of the first internal organ 48 in the position away from the second internal organ 50.
In a further embodiment of the apparatus of the invention shown in
The method of using the embodiment of the apparatus 54 shown in
The needle 62 is then passed through the inter-abdominal wall 42 and the needle 62 and the attached length of cord 56 are pulled from the insertion site 72 back into the abdominal cavity 46. This causes a first segment 74 of the cord length 56 to move into engagement with and across the first internal organ 48. The engagement of the first cord segment 74 with the first internal organ 48 moves the first internal organ 48 toward the position away from the second internal organ 50.
The needle 62 is then again inserted through the inter-abdominal wall 42 at a second insertion location 76 spaced from the first insertion location 72. The needle 62 and the attached length of cord 56 are pulled manually through the second insertion 76 into the abdominal cavity 46 until an intermediate section of cord 78 extends between the two insertion sites 72,76.
The needle 62 and the attached length of cord 56 are then passed through the knot 64 formed at the opposite end of the length of cord 56 and are pulled tight. This causes a second cord segment 82 of the length of cord 56 to engage across and move the first internal organ 48 toward the position away from the second internal organ 50. The length of cord 56 is pulled tight and a knot is tied between the opposite ends of the cord at the knot 64 on the cord second end 60. The portion of the length of cord 54 extending from the knot 64 to the needle 62 is then cut and removed from the abdominal cavity. The length of cord 54 left in the abdominal cavity forms a triangular loop with the first 56 and second 82 cord segments extending across the first internal organ 48 and holding the first internal organ in the position away from the second internal organ 50 without manual input. In this manner, surgical access is provided to the second internal organ 50 without manually holding the first internal organ 48 in its retracted position.
The apparatus 500 is comprised of a base 502 having a tubular configuration. More specifically the base 502 is formed as a cylindrical housing wall having a hollow interior bore extending entirely through the length of the base housing. A center axis 506 of the interior bore defines mutually perpendicular axially and radial directions relative to the base. The base cylindrical housing 502 has axially opposite first 508 and second 510 ends.
A first rod 512 and a second rod 514 are secured to the base. As shown in the drawing figures, the first rod 512 extends radially across the base interior bore adjacent the base second end 508. Opposite ends of the first rod 512 are secured to the base cylindrical housing 502. The second rod 514 extends radially across the base interior bore adjacent the base second end 510. Opposite ends of the second rod are secured to the base cylindrical housing 502.
A first tissue connector 516 extends from the base 502 at the base first end 508. In the example shown in the drawings, the tissue connector 516 has a hook 518 formed at one end and a ring 520 formed at the opposite end. The first rod 512 extends through the ring 520 and thereby connects the tissue connector 516 to the base 502. The hook 518 is employed in connecting the apparatus 500 to body tissue. The tissue connector shown in the drawing figures is only one example of a known type of tissue connector that could be employed with the apparatus 500. Any other type of known tissue connector could replace the tissue connector 516 shown in the drawing figures. Additionally, the first tissue connector could be an integral extension of the base.
A flexible cord 522 having a length with opposite first 524 and second 526 ends is attached to the base 502 at the base second end 510. An intermediate portion 528 of the cord is wrapped around the second rod 514 thereby attaching the cord 522 to the base 502. A first portion or first percentage 530 of the cord length extends from the intermediate portion 528 and from the base second end 510 to the cord first end 524. A second portion or second percentage 532 of the cord length extends from the intermediate portion 528 and from the base second end 510 to the cord second end 526.
The cord intermediate portion 528 is wrapped around the second rod 514 by being tied in a Munter hitch or Italian hitch knot 534 around the second rod 514. In
A second tissue connector 540 is provided on the cord second end 526. The second tissue connector 540 can be any known type of tissue connector used to attach to body tissue and is therefore shown only schematically in the drawing figures. A percentage of the cord length (the second percentage) extends between the first tissue connector and the second tissue connector. The percentage of the cord length extending between the first and second tissue connectors is intra-abdominally adjustable to increase the percentage of the cord length and to decrease the percentage of the cord length.
The apparatus 500 also includes a releasable one-way cord lock 542. The lock 542 has a cylindrical exterior surface and engages in sliding engagement with the interior surface of the base cylindrical housing 502. The lock 542 moves in axially reciprocating movements through the base interior bore between a first position of the lock shown in
An actuator 550 is mounted on the base 502 and is operatively connected to the reversible one-way cord lock 542. The actuator 550 is formed as a cylindrical sleeve that surrounds the base cylindrical housing 502. The opposite ends of the lock pin 548 project beyond the axial slots 546 in the base cylindrical housing 502 and are secured in opposite sides of the actuator 550. This operatively connects the actuator with the lock 542. The actuator 550 is mounted on the cylindrical housing of the base 502 for axially reciprocating movements between first and second positions of the actuator relative to the base. Moving the actuator 550 to its first position relative to the base 502 moves the one-way cord lock 542 to its first position relative to the base shown in
A biasing device urges the one-way cord lock 542 to its first position shown in
With the actuator 550 being moved to its second position and in turn the one-way cord lock 542 being moved to its second position shown in
The construction of the further embodiment of the apparatus 554 differs from that of the previous embodiment basically in the construction of the releasable one-way cord lock 556. The lock 556 has a lock protrusion 544 that functions in the same manner as the previous embodiment. However, the cylindrical configuration of the lock 556 extends beyond the base cylindrical housing first end 508 to an annual flange or rim 558 on an opposite end of the lock from the protrusion 554. This rim 558 functions as the actuator of the lock 556. The rim 558 surrounds a hollow center bore 560. The bore extends from the rim down into the lock 556 and ends short of the lock protrusion 544. A pair of axially extending slots 562 are formed in the opposite sides of the lock 556 and communicate the interior bore 560 with the exterior of the lock 556. The first rod 508 extends through the pair of slots 562. The engagement of the first rod 512 through the slots 562 enables the lock 556 to reciprocate between its first and second positions relative to the base 502, but prevents the lock 556 from rotating relative to the base. This maintains the protrusion 544 on the second radial side of the second rod 514.
The first tissue connector 516 is connected to the first rod 512 just as in the previous embodiment. The first tissue connector 515 extends from the first rod 512 to the hook 518 of the connector.
The biasing device in the form of the coil spring 522 is positioned in the interior bore 560 of the lock 556. The spring 552 is positioned between the first tissue connector ring 520 and the lock 556 and exerts a biasing force on the lock pushing the lock toward its first position relative to the base 502.
The releasable one-way cord lock 556 of the apparatus 554 functions in the same manner as the previously described apparatus in maintaining the Munter hitch knot 534 on the first radial side of the second rod 514 when the lock is in its first position relative to the base, and allowing the knot 534 to move to the second side of the second rod 514 when the lock is moved to its second position on the base.
Both embodiments of the apparatus have the same method of use. Basically, a portion of the cord is attached to body tissue on an opposite side of the abdominal cavity from the abdominal wall, an additional portion of the cord is attached to the abdominal wall positioning a length or percentage of the cord across the first internal organ, and then the length or percentage of the cord extending across the first organ is decreased thereby causing the decreasing percentage of the cord length to engage across and move the first internal organ away from the second internal organ. This is illustrated schematically in
The second tissue connector 540 of the apparatus 554 is then manually connected to tissue 52 adjacent to the first internal organ 48 and between the first 48 and second 50 internal organs. In the example shown in
The actuator 558 of the apparatus 554 is then released. This results in the spring of the apparatus moving the releasable one-way cord lock to its first position relative to the base 502.
The cord first portion 530 is then grasped and pulled from the base second end 510. This causes the knot to move to the first side of the second rod 514 and causes the length of the cord first portion 530 to increase (or increase in percentage) while decreasing the length of the cord second portion 532 (or decreasing the percentage of the cord second portion). The decreasing length of the cord second portion 532 is pulled tight across the first internal organ 48. Continuing the pulling force on the cord first portion 530 continues to decrease the length of the cord second portion 532 causing the cord second portion to move the first internal organ 48 toward the position away from the second internal organ 50. When the first internal organ 58 is in the desired position, the grasping and pulling force on the court first portion 530 is released. With the pulling force on the cord first portion 530 having moved the knot to the first radial side of the second rod 514, the lock protrusion prevents the knot from moving back to the second radial side of the second rod 514. With the knot maintained on the first radial side of the second rod 514, the length of the cord second portion cannot be increased. Therefore, the cord second portion 532 holds the first internal organ 48 in its position away from the second internal organ 50 as shown in
When it is desired to remove the apparatus 554 from the abdominal cavity the actuator 558 is again grasped and moved toward its second position on the base 502. This cases the lock to move to its second position and moves the lock protrusion away from the knot. This again allows the knot to move to the second side of the second rod 514 and allows the cord second portion 532 to be pulled from the base second end 510. This in turn allows the first internal organ 48 to return to its original position relative to the second internal organ 50. The increased length of the cord second portion 532 enables the first tissue connector 516 and second tissue connector 540 to be removed from their connections to the body tissue.
The method of using the apparatus shown in
In addition to the above, the fourth tissue connector 584 can be used to laterally displace or move the first internal organ in a sideways direction. This is accomplished by grasping the fourth tissue connector 584 with a surgical grasper and then pushing the first internal organ to one side or the other before securing the fourth tissue connector 584 to body tissue. This results in the fourth tissue connector 584 holding the first internal organ in its sideways displaced position.
As various modifications could be made in the constructions of the apparatus and the methods herein described and illustrated without departing from the scope of the invention, it is intended that all matter contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative rather than limiting. Thus, the breadth and scope of the present invention should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims appended hereto and their equivalents.
