At this time, the pressing portion 100 having a quadrangular structure is structurally stable, and can press a large area, so that the fixing action of the ligament 400/tendon is remarkably and efficiently performed.

On the basis of any of the above embodiments, the first rope 110 and the second rope 210 are tied, fixed or connected in a weaving manner.

The invention also provides a knitting method of the reticular wire loop device for fixing the avulsion fracture around or in the joint, which mainly comprises the formation of a suture tubular knitting mechanism and the knitting process of the reticular wire loop device.

The weaving of the netted thread ring device includes setting monofilament thread material on spindle with spindle weaving machine, and weaving the thread material alternately with the spindle. When the spindles meet, the spindles are mutually staggered, so that two groups of wires are mutually staggered, and the wires are mutually interwoven to form a suture tubular weaving mechanism with a tubular center.

In one form of weaving, see fig. 11, the woven tubular suture is used to weave again in a net shape, the weaving tool is used to thread from the end of the tubular suture D3 at the suture a along the inner diameter of the suture and to thread out at the right left 90 ° of the suture, D1 is threaded into the center of the D3 suture, the silk threads of the silk are used to sew and fix D3 and D1, and the rest of D1 and D4, D2 and D3, D2 and D4 are sewed and fixed by the silk threads of the silk according to the above method.

In another form of knitting, see fig. 12, the knitted tubular suture is used to perform the net-shape re-knitting, the knitting tool is used to penetrate from the end of the tubular suture D1 at the suture a along the inner diameter direction of the suture and to penetrate out from the position 60 ° to the right left of the suture, D3 is penetrated in the center of the D1 suture, then the silk threads are used to perform the sewing and fixing of D3 and D1, and the rest of D1 and D2, D2 and D3 are used to perform the sewing and fixing by the silk threads according to the above method.

Through the knitting process of the mesh-shaped wire loop device, the suture at the ring junction part can form the first rope 110 of the pressing part 100, and the suture thrown to the ring junction part forms the second rope 210 of the drawing part 200, so that the suture on the mesh-shaped wire loop device is ensured to be subjected to more uniform drawing force, and the operation of knotting and knitting the suture by a surgeon before an operation according to the operation requirement is omitted.

In the present invention, the thread is knitted by a spindle type knitting machine, see the working principle diagram of the spindle type knitting machine in fig. 13, and the knitting thread is led out by bobbins placed on creels 22, 22', 24'. The creels move along a closed circular loop 28, alternating in and out of the loop 28 to complete the weaving action, one or more creels moving successively along a helical path in one direction and the remaining creels moving along a helix in the other direction. Taking the creels 22, 22' for example, it moves in a clockwise direction while the remaining creels move along a helix in the other direction as indicated by arrow 23. The creel 26 placed in the loop is core wire placed. The creels 22, 22', 24' are thus moved to cross the braided wires with each other to form a sheath wire which is braided along a centrally placed core wire which is fed out by the creel 26 and the formed suture thread is drawn up by the take-up device.

Compared with the prior preoperative string bag suture weaving mode, the weaving method of the mesh wire loop device can effectively reduce the weaving operation of doctors and ensure that the suture in the mesh wire loop device is subjected to uniform traction force.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
