Description

Adjustable type femur osteotomy guider Technical Field The utility model relates to the technical field of guides, in particular to an adjustable femur osteotomy guide. Background Knee joint diseases can seriously affect daily life, and generally, a patient needs to be subjected to osteotomy, the diseased part is removed, an artificial knee joint prosthesis is replaced, and the patient is helped to recover walking ability. At present, when the femur is cut, in order to enable the section to be better attached to the prosthesis, the osteotome needs to be guided through the guide device, the phenomenon that the cutter is offset when cutting the femur can be prevented, but the existing guide device is generally fixed, when the positions of femur lesions are different, the positions of the femur lesions need to be cut are different, the angle of the osteotomy is difficult to adjust through the fixed guide device, and the use flexibility is low.
