BACKGROUND Field of TechnologyThe present disclosure relates to the repair of soft tissue and, specifically, devices for use in such repair.
Related ArtArthroscopic procedures often require soft tissue to be reattached to bone. To achieve this, anchors are placed in the bone and sutures attached to the anchor are passed through the tissue to securely retain the tissue in place. When making a repair of soft tissue to bone, it is advantageous for the suture anchor and the anchor inserter to have features that allow for ease of insertion and increased fixation of the anchor to the bone. A procedure, and devices for use in such procedure, that securely attaches tissue to bone is needed.
SUMMARYIn an aspect, the present disclosure relates to a suture anchor. The suture anchor includes a body having a proximal end and a distal end, the body including threads along at least a partial length of the body and at least one through hole, the threads including a profile such that the threads located near the distal end of the body include a first shape and the threads located near the proximal end of the body include a second shape different from the first shape.
In another aspect, the present disclosure relates to a delivery device. The device includes a square-shaped end including two prongs extending from the end, the prongs located at opposite corners of the end, wherein the device is cannulated.
In yet another aspect, the present disclosure relates to a delivery device. The device includes an end having a first area and a second area, wherein the first area is of a first shape and the second area is of a second shape different from the first shape, the first shape and the second shape including different diameters, the device being cannulated.
In a further aspect, the present disclosure relates to a delivery device. The device includes an end having a first area and a second area, wherein the first area is of a first shape and the second area is of a second shape different from the first shape, the first shape and the second shape including different diameters, the device being cannulated, wherein one of the areas includes tangs extending outwardly from the device.
In yet a further aspect, the present disclosure relates to an anchor dilator. The dilator includes a handle; a shaft coupled to the handle; and a dilating portion coupled a distal end of the shaft, the dilating portion including a body having threads, the threads including a profile such that the threads located near the distal end of the body include a first shape and the threads located near the proximal end of the body include a second shape different from the first shape.
In an aspect, the present disclosure relates to an anchor dilator. The anchor dilator includes a handle; a shaft coupled to the handle; and a dilating portion coupled to a distal end of the shaft, the dilating portion including a body having a threaded first portion and a non-threaded second portion, the threaded first portion including a profile such that threads located near a distal end of the body include a first shape and threads located near a proximal end of the body include a second shape different from the first shape.
Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the disclosure, are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.
The accompanying drawings, which are incorporated in and form a part of the specification, illustrate the embodiments of the present disclosure and together with the written description serve to explain the principles, characteristics, and features of the disclosure. In the drawings:
The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the disclosure, its application, or uses.

Once the anchor 10 has been inserted into the bone 30, the inserter 20 is removed from the anchor 10 and soft tissue 40 is placed adjacent to the anchor 10, as shown more clearly in

Other alternative features/embodiments are also within the scope of this disclosure. The distal ends of the anchors in
The distal end of the inserter may include more or less than two prongs. Additionally, it is within the scope of this disclosure to have a distal end with prongs that do not straddle a through hole. The shape of the distal end of the driver may be other than square and therefore have more or less than four sides. The anchors are made from a non-metal material via an injection molding process. However, other material, which would allow the anchors to withstand the forces applied during surgery, and other processes may be used. Also, the driver is made from a metal material. However, other material that would allow the driver to withstand the forces applied during surgery may be used. Rather than drilling pilot holes into the bone and then inserting the anchors into the bone via the holes, the anchors may be inserted by tapping on the end of the inserter to advance the pointed distal ends of the anchors into the bone and then rotating the inserter to advance the rest of the anchors. Also, rather than tying the ends of the sutures to fixate the tissue, the tissue may be fixated to bone in another manner, such as by passing the ends through a second anchor and then placing the second anchor into the bone at another location.

Prior to insertion of any of anchors 10,60,70,90, the anchor dilator 200 may be used to prep the bone for insertion of the anchor 10,60,70,90. The dilator 200 includes a shaft 201, a handle 202 coupled to a proximal portion 201a of the shaft 201, and a dilating portion 203 coupled to a distal portion 201b of the shaft 201. The dilating portion 203 has a body 203a similar to the body 71,91 of each of anchors 70,90 and a thread profile similar to the thread profile of anchors 10,60,70,90. During tissue repair, a hole is made in bone by inserting the dilating portion 203 into the bone in an axial and rotational motion such that the user may strike the handle 202 to insert the pointed distal end 203b and then rotate the dilator 200 to insert the rest of the dilating portion 203. The dilating portion 203 is then removed from the bone and one of the anchors 10,60 may be inserted into the hole similar to the method described above for
Similar to anchor dilator 200, anchor dilator 300, shown in
For the purposes of this disclosure, anchors 70,90 are made from a metal material, such as titanium. However, other materials could be used to make each of the anchors 10,60,70,90. Anchors 70,90 and their features may be formed from a machining process or other known processes. The delivery devices 80,100 are made from a metal material via a machining process or other known process. The devices 80,100 may be made from another material that would allow the devices 80,100 to withstand the forces applied to the devices 80,100 during insertion of the anchors 10,60,70,90. The anchor dilator 200,300 is made from a metal material, however, other materials that would allow the dilator 200,300 to withstand the forces applied to the dilator 200,300 during insertion of portion 203,303 into bone may be used. The dilator 200,300 may be made from a machining process or other known process. The delivery devices 20,80,100 include handles opposite the distal ends 21,81,101 of the devices 20,80,100.
As various modifications could be made to the exemplary embodiments, as described above with reference to the corresponding illustrations, without departing from the scope of the disclosure, it is intended that all matter contained in the foregoing description and shown in the accompanying drawings shall be interpreted as illustrative rather than limiting. Thus, the breadth and scope of the present disclosure 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.
