Embodiment Construction

[0021] The present invention proposes a custom-made and individualized artificial total hip joint replacement surgery femur preparation template system. Use the femoral preparation template system to determine the precise osteotomy of the femoral neck and prepare the femoral medullary cavity to obtain the ideal insertion position of the prosthesis, so that the position of the femoral prosthesis can be placed accurately during the operation, and the femoral prosthesis of the artificial total hip joint can be controlled Ideal position in the body to improve surgical results.

[0022] Below in conjunction with accompanying drawing, the realization mode of the present invention is described in detail by specific embodiment:

[0023] Such as Figure 1-7 As shown, this embodiment proposes a customized femur preparation template system for total hip replacement surgery, including a femoral neck osteotomy guide plate 1 and a femoral prosthesis anteversion angle and lateral edge guide...

Abstract

The invention provides a system for customizing an individualized artificial total hip joint replacement operation femur preparation template. The system comprises a femur neck osteotomy guide plate, a femur prosthesis anteversion and lateral border guide plate, the interior surface of the femur neck osteotomy guide plate is matched with a femur head, a femur neck, and a femur intermediate zone between a greater trochanter and a lesser trochanter in anatomic shape, the femur neck osteotomy guide plate is provided with an osteotomy positioning groove, the bottom of the femur prosthesis anteversion and lateral border guide plate is matched with a femur neck osteotomy surface in shape, the femur prosthesis anteversion and lateral border guide plate comprises a body, a lesser trochanter positioning wing and a front side wing, the lesser trochanter positioning wing and the front side wing are arranged on the body, and the body is provided with an anteversion and lateral border guide groove. According to the invention, the position of the ideal artificial total hip joint femur prosthesis in a human body can be controlled accurately, and furthermore the operation effect can be improved.

Description

technical field [0001] The invention belongs to the technical field of templates for artificial total hip replacement surgery, in particular to a customized and individualized femur preparation template system for artificial total hip replacement surgery. Background technique [0002] Total hip replacement is currently one of the most effective means of treating hip joint diseases in the world, and its therapeutic effect has been unanimously recognized by doctors and patients all over the world. However, one of the key factors affecting the effect of surgery is the position of the artificial total hip joint prosthesis and whether the normal hip joint anatomy and biomechanical characteristics can be restored after the prosthesis is implanted in the body, such as the length of the lower limb, the center of rotation of the hip joint, eccentricity, The size, position, angle of the prosthesis and the characteristics of the contact between the prosthesis and the bone are all deter...
