Example 1

Referring to fig. 1, a labral suture anchor includes anupper pin 1, alower pin 2, and asuture 3. The labrum suture anchor is adapted to mate with the aperture.

Referring to fig. 2, in the present embodiment, theupper nail 1 has a substantially cylindrical structure, the cross-sectional area of one end of theupper nail 1 is larger than that of the other end, and the smaller cross-sectional area end serves as the insertion end of theupper nail 1, so that the insertion of theupper nail 1 into the hole is facilitated due to the smaller cross-sectional area of the insertion end. Theupper nail 1 is coaxially provided with a throughhole 11. One end of theupper nail 1 with smaller cross section area is provided with a containinggroove 12 for containing thelower nail 2, one end opening of the containinggroove 12 is communicated with the outside, and the other end opening is communicated with the throughhole 11; the area of the slot at the end of the receivingslot 12 communicating with the outside is larger than the area of the slot at the end communicating with the throughhole 11, and the receivingslot 12 is approximately trapezoidal in fig. 2 in this embodiment. The outer side wall of theupper nail 1 is integrally formed with a plurality ofconvex rings 13 which are arranged at intervals. In this embodiment, the adjacentconvex rings 13 are equally spaced, and the cross section is triangular. The cross section of thecollar 13 may also be of other geometric shape, for example semi-circular. Thecollar 13 is able to press thesuture 3 against the inner wall of the hole.

Referring to fig. 3 and 4, thelower nail 2 includes twoextension parts 20, one end of eachextension part 20 is aconnection end 21, the other end is a spreadingend 22, the connection ends 21 of the twoextension parts 20 are fixedly connected, the spreading ends 22 of the twoextension parts 20 are far away from each other, so that thelower nail 2 is approximately V-shaped in fig. 3, and the end connected with the two connection ends 21 forms the tip part of the lower nail, so that thelower nail 2 is conveniently inserted into the hole. The cross-sectional area of theextension 20 increases gradually from the connectingend 21 to thedeployment end 22, and theindividual extension 20 is trapezoidal in the view of fig. 4. Thelower spike 2 is braided from afurther suture 3, preferably thesuture 3 may be made of a material absorbable by the human body, such as polylactic acid, polyglycolic acid, polylactic glycolate and polydioxanone. In this embodiment, eachextension 20 is provided with athreading hole 23 through which thesuture thread 3 passes, and the distance from the threadinghole 23 to the connectingend 21 is approximately equal to the distance from the connectingend 22 to the deploying end.

One end of thesuture thread 3 sequentially passes through the throughholes 11 of theupper nail 1, and after two threadingholes 23 of thelower nail 2, passes through the throughholes 11 again, so that theupper nail 1, thelower nail 2 and thesuture thread 3 are mutually connected.

The labrum suture anchor in the present application can fix thesuture 3 without knotting, and can also be used as a tape wire anchor.

The implementation principle of theembodiment 1 is as follows:

in operation, a stepped hole is drilled by a drill, and thelower nail 2 is implanted into the stepped hole using an inserter. And then theupper nail 1 and thesuture line 3 bypass the dislocated soft tissue, so that thesuture line 3 is sleeved on the dislocated soft tissue. Theupper nail 1 is aligned with the stepped hole while gradually tightening thesuture 3 until the soft tissue is fixed. Theupper spike 1 is then inserted into the stepped hole. At this time, theupper nail 1 and thelower nail 2 are fixed in the stepped holes, and the convex rings press thesuture thread 3 on the inner walls of the holes. The structure is used for realizing knotting-free fixation of thesuture line 3, simplifying the management of thesuture line 3, simplifying the whole operation and shortening the operation time.

When the structure is used as a string anchor, a hole is drilled, thesuture thread 3 is pulled by drilling, thelower nail 2 is accommodated in theaccommodating groove 12 of theupper nail 1, and theupper nail 1 and thelower nail 2 which are integrated are implanted into the hole through an inserter.

Example 2

Example 2 differs from example 1 in that: thelower nail 2 is not provided with athreading hole 23. Since thelower nail 2 is woven by theadditional suture thread 3, thelower nail 2 has a weaving slit, and when thesuture thread 3 is penetrated, thesuture thread 3 can be penetrated through the weaving slit to realize the connection with thelower nail 2.

The embodiment of the application also discloses a suture management method.

Example 3

Referring to fig. 1 and 5, a suture management method using the labrum suture anchor of example 1 includes the following steps.

S1: a drill is used to pre-form the stepped hole.

S2: thelower nail 2 is implanted into the stepped hole by the inserter. The inserter is of a hollow cylindrical structure, and during implantation, the inserter is arranged in the throughhole 11 of theupper nail 1 in a penetrating way, and thesuture 3 is arranged in the inserter in a penetrating way.

S3: theupper peg 1 andsuture 3 are passed around the dislocated soft tissue and theupper peg 1 is aligned with the edge of the hole.

S4: the end of thesuture 3 is pulled until thesuture 3 is tightened.

S5: theupper nail 1 is inserted into the stepped hole, and thesuture thread 3 is pressed against the inner wall of the hole.

The method realizes knotting-free fixation of thesuture line 3, simplifies the management of thesuture line 3, simplifies the operation process and shortens the operation time.

Example 4

Referring to fig. 6, a suture management method using the labrum suture anchor of example 1 includes the following steps.

S1: a drill is used to pre-form the cylindrical hole.

S2: thesuture thread 3 is pulled such that thelower spike 2 is located in the receivinggroove 12 of theupper spike 1. Since thelower nail 2 is made of thesuture thread 3, thelower nail 2 has a certain elasticity, is accommodated in theaccommodating groove 12 in an M shape, and a portion of thelower nail 2 near thedeployment end 22 abuts against an inner wall of theaccommodating groove 12.

S3: the upper andlower nails 1 and 2 are simultaneously inserted into the holes by the inserter.

The labrum suture anchor in the application can realize knotting-free fixation of thesuture line 3, can also be used as a strip line anchor, has a simple structure and convenient connection, greatly reduces suture management during operation, and improves operation efficiency.
