Problems solved by technology

[0002] With the continuous advancement of medical technology, artificial knee replacement surgery has gradually become a relatively common surgical operation. The usual practice on the femoral side is to perform osteotomy after distal femoral osteotomy using the complete anterior or posterior femoral condyle as a reference. However, it often occurs that the patient’s anterior or posterior femoral condyle has been worn out, diseased, or damaged during the operation, so it cannot be used as a reference for osteotomy. At this time, the doctor’s experience is generally used to determine the osteotomy position , resulting in prolongation of operation time, dependence on doctor's experience and increase in operation failure rate

Embodiment Construction

[0020] The specific implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 , figure 2 Shown, femur distal end scriber of the present invention, the scriber tool that is used to draw through the condyle line after distal femur osteotomy in knee joint replacement surgery, femoral distal end scriber comprises fixed end (1), movable end ( 2), the positioning column (3), the marking groove (4), the fixed end (1) and the movable end (2) are interspersed together, and other movement modes except the axial movement are restricted, and the positioning column (3) has two One, respectively fixed on the two ends of the fixed end (1) and the movable end (2), respectively fixed on both sides of the femoral condyle, the marking groove (4) is a part of the movable end (2).

[0022] Such as Figure 4 As shown, adopt distal femur scriber of the present invention, after distal femur osteotomy,...

Abstract

The invention relates to a mark scraper for the thigh bone far end. The mark scraper is a marking tool used for marking a condyle through line after the thigh bone far end is cut in the knee prosthesis operation. The mark scraper for the thigh bone far end comprises a fixed end, a movable end, a locating column and a marking slot, wherein the lower end faces of the fixed end and the movable end are located on the same plane and are attached to the cut thigh bone far end, the locating column is attached to the protrusion of the outer side condyle of the thigh bone after the far end is cut and the depression of the inner side of the inner side condyle of the thigh bone, the condyle through line marked by the marking slot provides reference for cutting the thigh bone, and dependence on the front condyle or the rear condyle of the complete thigh bone is reduced.
