Femoral calcar osteotomy positioning guide platform

Abstract

The invention discloses a femoral calcar osteotomy positioning guide platform, belongs to the technical field of orthopedic surgical instruments, and plays an auxiliary positioning role of femoral neck osteotomy in an orthopedic hip replacement surgery. The technical scheme includes that the upper portion of the femoral calcar osteotomy positioning guide platform is a guide surface, and the lower portion of the femoral calcar osteotomy positioning guide platform is a positioning seat. The upper end of the guide surface is a plane, and a circular-arc positioning groove is reserved on the inner side of the plane. The circumferential shape of the positioning groove is matched with the circumference of the femoral calcar, and the inner side surface of the positioning seat is matched with the circumference of the femoral calcar. A locking slot is reserved on the lower portion of the positioning seat, and the circumference of the locking slot is matched with the circumference of the upper portion of a small rotator. A doctor uses a goose saw to perform the osteotomy along the guide surface, so that an osteotomy surface is smooth and is matched with a mounting angle of an orthopedic hip replacement prosthesis, and the long-existing problem that the osteotomy surface and the angle of the femur cannot meet an ideal requirement in the orthopedic hip replacement surgery is solved. The femoral calcar osteotomy positioning guide platform is simple in structure and convenient to use, good in effect of the osteotomy, capable of shortening time of the surgery, valuable in popularization and application, and is an ideal auxiliary instrument to perform the osteotomy on the femur in the orthopedic hip replacement surgery.

Description

technical field [0001] The invention relates to an auxiliary appliance for performing osteotomy on the femoral neck in orthopedic hip joint replacement surgery, and belongs to the technical field of orthopedic surgical appliances. Background technique [0002] As my country enters into an aging society, osteoporotic femoral neck fractures are becoming more and more common in the elderly over 65 years old. Total / half hip arthroplasty has become the preferred treatment method for patients with displaced femoral neck fractures. In hip replacement surgery, it is necessary to perform osteotomy on the residual femoral neck to find a suitable installation plane for the hip joint prosthesis, which has relatively strict requirements on flatness and plane angle. First of all, the flatness of the plane should be straight, without protrusions or depressions, so that the hip joint prosthesis can be in close contact with the installation plane, so that the postoperative connection can be ...

AI Technical Summary

Problems solved by technology

However, due to the limited exposure and deep position of the femoral neck to be osteotomized during the operation, and the lack of a suitable and dedicated osteotomy positioning and guiding platform, the operation of this type of operation has brought great inconvenience.

Clinicians can only rely on experience to operate, which makes it very difficult for the installation plane of the hip joint prosthesis to meet the ideal surgical requirements, which not only prolongs the operation time, but more importantly, affects the surgical effect, which is not conducive to the patient recover

This situation has not been fundamentally changed so far, and it has become the main factor restricting the ideal effect of orthopedic hip replacement surgery, and it is necessary to take measures to solve it
