Embodiment Construction

[0028] The present invention proposes a customized and individualized artificial total hip joint replacement surgery acetabulum preparation template system. Use the acetabular preparation template system to control the degree and direction of the acetabular rasp to obtain the ideal placement position of the acetabular prosthesis, and obtain the same position of the artificial total hip joint prosthesis in the body as the preoperative design, thereby improving the surgical effect .

[0029] Below in conjunction with accompanying drawing, the realization mode of the present invention is described in detail by specific embodiment:

[0030] Such as Figure 1-5 As shown, this embodiment proposes a customized and individualized acetabular preparation template system for artificial total hip replacement surgery, including an acetabular positioning guide plate 1, a depth control drill 2 and a colored depth indicating rod. The acetabular positioning guide plate 1 is attached and posi...

Abstract

The invention provides a fabrication template system for custom individual artificial total hip replacement operation acetabulum. The system comprises an acetabulum positioning guide plate, a depth control drill and a colored depth indication rod. The acetabulum positioning guide plate comprises a fossa ovalis positioning plate, an acetabulum bottom positioning plate and a depth guide cylinder. The fossa ovalis positioning plate is attached to the fossa ovalis according to the fossa ovalis dissection shape. The acetabulum bottom positioning plate is arranged at the outer edge of the fossa ovalis positioning plate and is attached to the acetabulum cartilage face according to the acetabulum dissection shape. The depth guide cylinder is arranged on the acetabulum bottom positioning plate and performs guide and depth limitation on the depth control drill. The depth control drill performs drill on the acetabulum through the depth guide cylinder, a depth limit ring protruding from the drill is arranged on the body portion of the depth control drill, and the depth limit ring is limited at the end of the depth guide cylinder through the depth guide cylinder. The length of the colored depth indication rod is identical to the drill hole depth, and the colored depth indication rod is inserted into the hole to indicate the depth and direction. By means of the template system, the ideal acetabulum prosthesis arranging position can be obtained, and accordingly, the acetabulum prosthesis can be arranged accurately, and the operation effect is 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 artificial total hip replacement surgery acetabulum preparation template system. 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 limbs, the symmetry of the hip joints on both sides, The size and position of the prosthesis and the characteristics of the contact between the prosthesis and the bone are all determined by th...
