Composite six-in-one osteotomy plate

Abstract

The invention discloses a compound six-in-one bone cutting plate. The compound six-in-one bone cutting plate is composed of eight parts, namely a front fixing nail hole, a side fixing nail hole, a femoral condyle front face measurer, a femoral condyle remote-end chamfering bone cutting groove, a posterior condylar bone cutting groove, a femoral condyle intercondylar bone cutting hole, a femoral condyle remote-end drilled hole and a femoral condyle intercondylar bone cutting observing hole. The eight parts are combined integrally to serve as a manual Knee joint prostheses replacement operating tool. The front fixing nail hole and the side fixing nail hole function in mounting and fixing; the femoral condyle front face measurer functions in measuring the size of the femoral condyle front face bone cut quantity; the femoral condyle remote-end chamfering bone cutting groove functions in guiding a femoral condyle remote-end chamfering bone cutting blade; the posterior condylar bone cutting groove functions in guiding a posterior condylar bone cutting blade; the femoral condyle intercondylar bone cutting hole functioning guiding in femoral condyle intercondylar bone cutting; the femoral condyle remote-end drilled hole functioning in guiding in a femoral condyle remote-end guide pin hole drilling; the femoral condyle intercondylar bone cutting observing hole functioning in observing the femoral condyle intercondylar bone cutting state.

Description

technical field [0001] The invention relates to a composite six-in-one osteotomy plate, which is applied to total knee replacement in surgical implant artificial knee replacement. Background technique [0002] Surgical implant artificial knee arthroplasty has been around for quite a long time, in which the prosthetic femoral condyle is implanted into the human body, and a femoral condyle osteotomy tool is required. General medical device companies use multiple sets of osteotomy guides when performing femoral condyle osteotomy. These osteotomy guides require testing of the femoral condyle size, measuring positioning and guiding the osteotomy. The problem caused by multiple sets of osteotomy guides is that there are many and heavy surgical instruments, and the joints and cooperation between the osteotomy guides are prone to errors, and the use is complicated and error-prone. Multiple sets of osteotomy guides are used together, which puts forward higher requirements on the sk...

AI Technical Summary

Problems solved by technology

To complete these functions, a lot of auxiliary equipment is needed, the operation is complicated, and the technical requirements are high.

[0004] Although some companies strive to simplify the design and reduce the size of the femoral condyle osteotomy plate, the effect is not very good because the simplification will affect the scope of application, and reducing the size of the femoral condyle osteotomy plate will affect the accuracy of osteotomy
