Embodiment Construction

[0038] Contraction below Figure 1-7 Further detailed description of the present application.

[0039] Embodiments of the present application discloses a novel femoral condyle resection assembly.

[0040] Refer figure 1 with figure 2 A novel osteotomy femoral condyle component, a surface of formula knee replacement surgery, the body 1 includes a curved, arc body 1 with the first end surface of the femur after osteotomy curvature coincide, the main body 1 close to the trochlear position defines a cutout portion 11 is provided with a cutout portion 11 with using the trochlear notch portion 11 on member 2. By the femoral notch 11 secondary cutting can be precisely determined trochlear osteotomy site required position.

[0041] Refer figure 2 with image 3 , A one side near the end surface of the femoral body 3 is provided with a cross member, the cross member 3 located at one end of the body 1 remote from the module 21 and the trolley 1 is connected to the active body.

Abstract

The present application relates to the field of orthopedic surgical equipment, in particular to a new type of femoral condyle osteotomy assembly, which includes an arc-shaped body that matches the curvature of the end face of the femur. The notch part of the osteotomy is provided with a femoral trochlear part used in conjunction with the notch part. The notch provided on the main body of this application can be used to determine the position of the femoral trochlea that needs secondary osteotomy. After the secondary osteotomy is completed, the femoral trochlea is covered on the notch to form a complete femoral condyle. It is close to the effect of the natural femoral condyle of the human body.

Description

Technical field [0001] The present application relates to the field of orthopedic surgery equipment, particularly relates to a novel femoral condyle resection assembly. Background technique [0002] Modern knee replacement surgery is the use of artificial biomaterials joint replacement and reconstruction of lesions to alleviate symptoms, eliminate pain, restore and improve joint function and improve quality of life. Of bone necrosis, bone fractures and joint disease can not be reset by the tail, pain and movement disorder, difficult, stiffness and other symptoms of rheumatoid arthritis or activities can be significantly reduced or eliminated, there will be some degree of joint range of motion improving the appearance of physical deformation can be significantly improved. [0003] Artificial knee replacement surgery is a positive effect, but higher technical requirements. Intercondylar osteotomy positioning accuracy will affect the stability of the prosthesis, it will increase the...
