Abstract

The present invention provides a tibial guide plate for total knee joint replacement surgery and a method for using the same. The bone groove runs through one end of the tibial guide plate body, and the tibial osteotomy groove is inserted with a sickle blade; the second side of the tibial guide plate body is provided with a fitting groove; one end of the tibial guide plate body is provided with a line of force parallel to the tibial osteotomy groove As for the rod fixing plate, the end of the force wire rod fixing plate away from the body of the tibial guide plate is provided with a force wire rod socket which is configured to be able to insert a force wire rod. The present invention realizes alignment and fitting with the anterior medial side of the tibia by setting the fitting groove, ensures the precise positioning and assembly of the tibial guide plate and the tibia, aligns the tibial osteotomy groove with the tibial osteotomy surface, and inserts the sickle blade into the tibial osteotomy groove , realize accurate verification of tibial osteotomy, ensure accurate positioning of surgical osteotomy, improve surgical safety and success rate, simple structure, convenient operation, and accurate positioning.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tibial guide plate for total knee joint replacement and a method for using the same. Background technique [0002] The success of total knee arthroplasty (TKA) depends on the positioning, clearance and soft tissue balance of the knee joint, all of which depend on the correct placement of the prosthesis. In traditional TKA surgery, the deviation of the lower limb force line is only judged according to the knee joint X-ray or CT before operation, which affects the angle judgment and may lead to surgical errors. At the same time, most of the traditional osteotomy positioning is achieved through TKA embracing instruments. There are many surgical instruments, heavy weight, and complicated assembly methods, which cannot guarantee the accuracy of positioning. Contents of the invention [0003] The present invention provides a tibial guide plate for total knee joint replacem...
