Abstract

The invention discloses a distal femoral osteotomy alignment and positioning device which is connected to a femoral resection protection block through a femoral osteotomy positioning guider, wherein the distal femoral osteotomy alignment and positioning device includes a swing table, a swing positioning piece and a positioning rod. The swing table is provided with a mounting hole, one end of the positioning rod extends into the mounting hole, and the swing positioning piece is fixedly connected with the swing table and can rotate along with the swing table relative to the positioning rod; theinner part of the positioning rod is provided with a through hole extending in the length direction of the positioning rod; an intramedullary rod passes through the through hole and is inserted into adistal femur during operation; the swing table is also provided with a guide hole, the guide hole extends from the upper surface of the swing table to the lower surface of the swing table, and the guide rod is inserted into the guide hole. The device can position the rotation angle of the device through the swing structure, has intuitive operation, and can effectively reduce misoperation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for aligning and positioning the distal end of a femoral osteotomy. Background technique [0002] In orthopedic diagnosis, many patients need osteotomy due to human bone damage or other bone pathological changes and deformities caused by various accidents. [0003] Taking the knee joint as an example, an artificial knee joint prosthesis is usually placed after the diseased part is removed through osteotomy of the patient. Knee replacement osteotomies generally include distal femoral osteotomy, proximal tibial osteotomy, condylar osteotomy, and patella osteotomy. [0004] Because the shape of the amputation and the plant prosthesis need to match in position, accurate positioning of the osteotomy site is required. The operation of the traditional femoral osteotomy positioning device is time-consuming and laborious, requiring both hands to rotate the button to ensure a cert...
