Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a titanium plate structure with a loop which is easy to adjust. Background Art

[0002] The titanium plate with loops is a medical product used for ligament or tendon reconstruction surgery. The titanium plate with loops is usually composed of a titanium plate, a wire loop, a traction wire and a flip loop wire. The titanium plate with loops fixation method is a surgical method for cruciate ligament reconstruction. This method does not require an additional lateral condylar incision. The upper end of the ligament graft without bone blocks at both ends can be firmly fixed in the femoral bone tunnel by using the built-in titanium plate with loops. It is a relatively mature and effective method in the current technology of ACL reconstruction using semitendinosus tendon, gracilis tendon and other non-bone grafts. The existing titanium plate with loops has certain disadvantages when used. When the existing titanium plate with loops is used, the size of the titanium plate with loops is usually fixed, while people's height and weight are diverse. When performing cruciate ligament reconstruction surgery for people of different heights, the titanium plate with loops has a high internal fixation failure rate when fixed, which increases people's surgical costs and cannot meet people's needs.
