Embodiment Construction

[0020] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a composite six-in-one osteotomy plate is composed of anterior fixation screw hole 1, side fixation screw hole 2, femoral condyle anterior face measurer 3, femoral condyle distal chamfer osteotomy groove 4, femoral condyle posterior condyle Osteotomy slot 5, femoral condyle intercondylar osteotomy hole 6, femoral condyle distal drilling 7, femoral condyle intercondylar osteotomy observation hole 8 are composed of eight parts. After the above eight parts form a whole, it can be used as a surgical tool for artificial knee joint prosthesis replacement.

[0021] The composite six-in-one osteotomy plate fixes the osteotomy plate and the human femoral condyle 14 in an appropriate position through the fixation nail 9 passing through the front fixation nail hole 1 and the side fixation nail hole 2 to play the role of installation and fixation. Femoral condyle anterior face m...

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...
