Intercondylar osteotomy module

Abstract

The invention belongs to the field of medical apparatuses, and discloses an intercondylar osteotomy module. The intercondylar osteotomy module comprises an osteotomy module and a positioning module, wherein a notch part is formed at the bottom of the osteotomy module, and the positioning part can be fixed in the notch part in a dismountable manner, so that when the positioning module is fixed in the notch part, the shape jointly formed by the osteotomy module and the positioning module is consistent with that of a preset femur condyle prosthesis, and when the positioning module is removed fromthe notch part, the notch part can be used as an osteotomy opening. The intercondylar osteotomy module disclosed by the invention can improve the accuracy of an intercondylar osteotomy position and osteotomy quantity so as to avoid repeated osteotomy amendment during subsequent femur condyle prosthesis mounting due to inaccurate osteotomy position or inaccurate osteotomy quantity.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to an intercondylar osteotomy module. Background technique [0002] The Knee Intercondylar Osteotomy Module is an instrument for performing osteotomy on the intercondylar portion of the femur during knee replacement surgery for surface knee replacement surgery. In superficial knee arthroplasty, the first osteotomy of the human femoral condyle is firstly performed, and the human femoral condyle after osteotomy is installed such as figure 1 As shown in the existing intercondylar osteotomy module 100', the intercondylar osteotomy module 100' can perform a second osteotomy on the intercondylar part of the femoral condyle, that is, at the opening 1' of the intercondylar osteotomy module 100'. Secondary osteotomy, remove the intercondylar osteotomy module 100' afterwards and install the femoral condyle trial mold (the shape is completely consistent with the shape of the fem...

AI Technical Summary

Problems solved by technology

[0003] Although the existing intercondylar osteotomy module 100' can realize the determination of the intercondylar osteotomy position and the amount of osteotomy in surface knee surgery, and ensure the placement of the femoral condyle prosthesis to realize the function of the knee joint, in view of its In the above-mentioned use process, when the intercondylar osteotomy module 100' is used for secondary osteotomy, the accuracy of the osteotomy position and the amount of osteotomy cannot be effectively guaranteed, resulting in the inability to ensure its effective installation when the femoral condyle trial mold is subsequently installed. It is necessary to remove the femoral condyle trial mold and then apply the intercondylar osteotomy module 100' for osteotomy again to ensure the function of the knee joint when the femoral condyle trial mold and the platform pad prosthesis are adapted, thereby further ensuring subsequent installation Knee joint function realized by femoral condyle prosthesis and platform pad prosthesis after femoral condyle prosthesis

[0004] In view of the defects in the prior art, those skilled in the art would like to propose a method that can improve the accuracy of the intercondylar osteotomy position and the amount of osteotomy, so as to avoid subsequent installation due to inaccurate osteotomy position or osteotomy amount. Intercondylar osteotomy module that requires repeated osteotomy revisions for femoral condyle prosthesis
