Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The preferred mode of knotting is to achieve anchor fixation without the need for knotting, and the knotless anchors with thread are designed to save operating time and avoid the effect of large thread knots on underlying fixed soft tissue. For this purpose, the present embodiment provides a loop wire anchor fixing system, as shown in fig. 1-6, comprising an anchor 1 and a loop type suture 2 preset with a loop portion 3, wherein the anchor body is a screw-in type structure, the screw-in structure is a thread structure arranged around the outer wall of the anchor body, the thread structure is only schematically illustrated in the figure, the thread is actually processed to ensure that the screw-in bone canal is not loosened, and the form and the thread pitch can be combined in various ways. Anchor 1 is of a conventional construction and will not be described in detail. The free end of the snare suture 2 is passed through the middle of the anchor 1 to form one or more closed snares 3 at the top. The snare portion 3 is designed with various forms of thread ends to fit a suture gun through tissue for use. The system is convenient to use for fixing the soft tissue, the fixing effect can be realized even without knotting, the knotting process is realized by the snare wire with simple structure and convenient operation, and the system is convenient and rapid and can avoid the risk caused by the conventional knotting error.

Further, the size of the collar portion 3 may or may not be adjustable. The collar portion 3 comprises an adjustable coil 4, for example as shown in fig. 5, by adjusting the adjustable coil 4 the size of the collar portion 3 can be adjusted.

Alternatively, as shown in fig. 1-5, the free end of one of the snare sutures 2 is closed to form the snare portion 3, and the free end of the other snare suture 2 is open.

Alternatively, as shown in fig. 6, the free end of one of the snare sutures 2 is closed to form the snare portion 3, and the free end of the other snare suture 2 is also closed to form the snare portion 3.

Specifically, as shown in fig. 1 and 6, the loop portion 3 is formed by branching a free end of one snare suture 2 into two snare sutures 2.

Specifically, as shown in fig. 2 and 4, the loop portion 3 is formed by closing the free ends of two of the snare-type sutures 2.

Specifically, as shown in fig. 3, the loop portion 3 is formed by closing the top of the anchor 1 extending from the middle of the snare suture 2.

The working process of the embodiment: as shown in fig. 7, firstly, an anchor 1 is implanted at a proper position of a tissue to be repaired, a suture gun is used for drawing a tail end wire end (loop portion 3) of a loop thread to penetrate through the tissue to form three supporting points, and then the suture thread 2 is crossed back and forth to penetrate through the loop portion 3 and tightened to realize knotting operation; in some embodiments, as shown in fig. 8-10, several snare wire anchors may be implanted simultaneously in-line, cross-connected two-by-two after passing through tissue using a wire guide, and fixed at the anchor holes with out-of-line anchors 5 to form a triangular integral fixation area; in other embodiments, as shown in fig. 11, three groups of loop wire anchors are implanted simultaneously in the inner row, and two loops are mutually crossed, penetrate through the snare tissue and are tightened to directly form the triangular fixation of the inner row.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
