Embodiment 1

[0048] figure 1 A schematic diagram of the three-dimensional structure of the cruciate ligament repair structure provided in the embodiment of the present invention; figure 2 It is a schematic diagram of threading the first suture in the cruciate ligament repair structure provided by the embodiment of the present invention; image 3 A schematic diagram of the second suture thread in the cruciate ligament repair structure provided by the embodiment of the present invention; Figure 4 This is a top view of the fixing plate in the cruciate ligament repair structure provided by the embodiment of the present invention.

[0049] like Figure 1 to Figure 4 As shown, the cruciate ligament repair structure provided by the present invention includes: a fixing plate 1 and a suture, and the fixing plate 1 is provided with two thread holes;

[0050] There are two sutures, the suture is inserted through one of the thread holes, wound into a coil 6 and passed out from the other thread ho...

Embodiment 2

[0068] In order to increase the service life of the suture thread, in any of the above solutions, further, an anti-cutting groove 8 is provided between the adjacent thread holes. Prevent the edge of the fixing plate 1 from cutting the suture, which will affect the life of the suture.

[0069] The anti-cutting groove 8 can be provided on one side or both sides of the fixing plate according to requirements to protect the suture.

[0070] In order to prevent the suture thread from being worn, in any of the above solutions, further, a smooth surface is provided between the groove bottom of the anti-cutting groove 8 and the hole wall of the thread hole. Or the inclined surface inclined to the hole wall to prevent the suture from being worn, and the rest are the same as the above-mentioned embodiment, and will not be repeated here.

[0071] The two sides of the fixing plate 1 through the wire hole are respectively provided with connecting holes for connecting the pulling wire, and ...

Abstract

The invention relates to the technical field of medical apparatuses, and provides a cruciate ligament repairing structure and method. The cruciate ligament repairing structure comprises a fixed plateand two suture lines, and two line holes are formed in the fixed plate; the suture lines penetrate through one line hole, are wound into line loops, penetrate out of the other line hole, and finally return back to penetrate through the first penetrated line hole; the line holes which the two suture lines penetrate through are different, and after winding to form line loops, the end portions of thetwo suture lines are connected. According to the cruciate ligament repairing structure, after the two suture lines are wound into the line loops, the lengths of the line loops can be adjusted, it isavoided that the problems of hole drilling and the length of a transplant influence the fixing effect of a belt carrier titanium plate, and the cruciate ligament repairing structure and method have the advantages that the cost is low, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cruciate ligament repair structure and a repair method with high surgical success rate. Background technique [0002] In arthroscopic surgery to repair a torn cruciate ligament in the knee, separate tunnels are drilled in the tibia and femur, and then ligament grafts are secured in the connected tunnels. The femoral end was fixed with transverse screws, interface screws, and a titanium plate with a loop, and the tibial end was fixed with an interface screw and a titanium plate with a loop. [0003] During the fixation process, sutures need to be used to pull the ligament graft into the bone tunnel. The length of the suture can be adjusted to maximize the amount of ligament grafts located in the bone tunnel. The existing coil length is fixed and cannot be adjusted. Measure and calculate, so as to achieve the effect of fixing the titanium plate with the loop. [0004] T...
