Abstract

The invention discloses a device for unicompartmental knee arthroplasty femoral condyle positioning and tibia osteotomy accuracy judgment, which is characterized by comprising a kirschner wire, a traction cone, a traction triangular piece and a femoral condyle test mold positioner anti-rotation fixing column, and the traction triangular piece and the traction cone are arranged on the silk thread from top to bottom. The device has the following advantages that the structural design is reasonable, the surgical operation can be more accurate, a satisfactory imaging result can be obtained in post-operation radiography, post-operation complications are reduced, and the device has good popularization prospects and medical value.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for unicondylar replacement femoral condyle positioning and tibial osteotomy accuracy judgment. Background technique [0002] At present, in the unicondylar replacement of the Oxford movable spacer, both the osteotomy surface of the tibial plateau and the positioning of the femoral condyle prosthesis are one of the most critical issues. In the current operation, Oxford movable spacer unicondylar replacement has its standard operating procedure. For experienced operators, most of the osteotomy of the tibial plateau and the placement of the femoral condyle prosthesis are skilled in operation, and the placement of the prosthesis It is relatively accurate, but for beginners, there are corresponding problems in tibial plateau osteotomy and femoral condyle placement, which lead to some postoperative complications and bring some problems to patients and operators, espec...
