This application is a continuation of U.S. patent application Ser. No. 13/031,352 filed Feb. 21, 2011, which claims the benefit of and priority to U.S. Provisional Application Ser. No. 61/355,379 filed on Jun. 16, 2010, and the disclosures of each of the above-identified applications are hereby incorporated by reference in their entirety.
BACKGROUNDTechnical Field
The present disclosure relates to a flexible access assembly for use in single incision surgical procedures. More particularly, the present disclosure relates to a flexible access assembly having a mechanism for the removal of bodily fluids.
Background of Related Art
Today, many surgical procedures are performed through small incisions in the skin, as compared to the larger incisions typically required in traditional procedures, in an effort to reduce both trauma to the patient and recovery time. Generally, such procedures are referred to as “endoscopic”, unless performed on the patient's abdomen, in which case the procedure is referred to as “laparoscopic”. Throughout the present disclosure, the term “minimally invasive” should be understood to encompass both endoscopic and laparoscopic procedures.
During a typical minimally invasive procedure, surgical objects, such as surgical access devices (e.g., trocar and cannula assemblies) or endoscopes, are inserted into the patient's body through the incision in tissue. In general, prior to the introduction of the surgical object into the patient's body, insufflation gases are used to enlarge the area surrounding the target surgical site to create a larger, more accessible work area. Accordingly, the maintenance of a substantially fluid-tight seal is desirable so as to prevent the escape of the insufflation gases and the deflation or collapse of the enlarged surgical site.
To this end, various access devices with valves and seals are used during the course of minimally invasive procedures and are widely known in the art. However, a continuing need exists for surgical access devices that can facilitate the accessibility of an underlying tissue site with relative ease and with minor inconvenience for the surgeon.
SUMMARYAccordingly, an access assembly for insertion through a single incision is disclosed herein. The access assembly includes a body, e.g., a foam body, having a proximal end and a distal end and a plurality of lumens extending through the foam body, each of the lumens including a sleeve extending at least a portion of the length of the body. The foam body includes a central portion and a lower rim at a distal end of the central portion. The lower rim defines a circular recess, about the body, along a proximal side of the lower rim.
The body has an upper rim at a proximal end of the central portion. Both the lower rim and an upper rim have a diameter greater than a diameter of the central portion. The access assembly may define four lumens. The sleeves are integrally formed with the body, or instead, the sleeves may be securely affixed with the body. The sleeves may be formed from one polymer and plastic. The sleeves may define a circular cross-section. The sleeves may include a braided material. The access assembly may further include one or more cannula assemblies inserted through the plurality of lumens. The body may include a Parylene coating. Various other coatings, e.g., hydrophilic, hydrophobic, bio-agents, anti-infection, analgesic, may also be employed.
Various embodiments of the present disclosure are described hereinbelow with reference to the drawings, wherein:
Other features of the present disclosure will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the present disclosure.
DETAILED DESCRIPTIONEmbodiments of the presently disclosed access assembly will now be described in detail with reference to the drawings wherein like numerals designate identical or corresponding elements in each of the several views. As is common in the art, the term “proximal” refers to that part or component closer to the user or operator, i.e. surgeon or physician, while the term “distal” refers to that part or component further away from the user.
One type of minimal invasive surgery described herein is multiple instrument access through a single surgical port. This technique is a minimally invasive surgical procedure, which permits a surgeon to operate through a single entry point, typically the patient's navel. The disclosed procedure involves insufflating the body cavity with a housing member positioned within an opening in the patient's skin. Instruments including an endoscope and additional instruments such as graspers, staplers, forceps or the like may be introduced within the port to carry out the surgical procedure. The presently disclosed access port may be used with a surgically created incision, a naturally occurring opening such as the anus or the vagina, or in non-laparoscopic procedures.

With reference still to
A vertical lumen 42 extends through the body 12 and connects with a horizontal lumen 44 to produce a longitudinal passageway 43 that extends from the proximal end 26 of the central portion 22 to a horizontal passageway 45 that extends into the recess 40. It is contemplated that passageway 43 and/or passageway 45 may be coated with an anti-coagulant.
As disclosed, the recess 40 is defined by a semi-circular cross-section. However, it is contemplated that any cross-sectional shape may be used. It is also contemplated that the horizontal lumen 44 may intersect with the recess 40 from any relative position, including along a bottom of the recess 40. It is further contemplated that the cross-sectional shape may vary about a circumference of the recess 40.
Lumens 16, 18, 20 extend through body 12 and define longitudinal axes configured to receive a cannula assembly 50 (

Upon completion of the procedure, cannula assemblies 50 and valve assembly 60 are removed from respective lumens 16, 18, 20. Access assembly 10 is then compressed or squeezed such that it may be removed from incision “I”. Incision “I” is then closed in a conventional manner.

It will be understood that various modifications may be made to the embodiments disclosed herein. For example, as noted hereinabove, the disclosed flexible access assembly may be provided with multiple lumens in excess of the disclosed three lumens. Additionally, the diameters or configuration of the disclosed lumens need not be identical but may be varied depending upon the contemplated surgical instruments to be utilized therethrough. Therefore, the above description should not be construed as limiting, but merely as exemplifications of particular embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto.
