Personal guide device of implanting anteversion angle for femoral stem prosthesis

Abstract

The invention relates to a personal guide device of implanting anteversion angle for a femoral stem prosthesis, characterized by comprising a bone attaching plate and a guide plate; the bone attachingplate and the guide plate are formed in a whole at a time; the shape of the bone attaching plate is designed by reference to the design of the outer surface of the femur matched with the bone attaching plate; the bone attaching plate is of curved structure; a curved face of the bone attaching plate matches with the outer surface of the proximal end of the femur; a guide face fits an osteotomy face; the guide face matches with a preoperatively-set prosthesis side; the guide plate and the osteotomy are fitted to form a receiving channel. The personal guide device has the advantages that the personal guide device is designed according to personal bones, intraoperative precise positioning is available, the implanting anteversion angle of the prosthesis can be accurately determined, the relationship between the guide face and the prosthesis is clear, and the personal guide device has a promising application prospect in the replacement of artificial hip joint.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to a personalized femoral stem prosthesis implantation anteversion angle guide device. Background technique [0002] The femoral stem prosthesis is a part of the hip joint prosthesis, which is used in artificial hip joint replacement surgery to reconstruct the anatomical structure of the human hip joint, and to restore normal mechanical properties or complete certain physiological functions. Relieve pain, improve function and quality of life. The artificial hip joint is composed of the femoral stem and the femoral head. The femoral stem, as the connecting part connecting the human femur and the distal end of the human body, plays a role of fixation and support in the human body. treatment effect. [0003] The angle of femoral stem prosthesis placement determines whether the anteversion angle of the femoral neck can return to normal. If the anteversion angle is t...
