Posterolateral approach total hip joint replacement surgery teaching model

Abstract

Disclosed is a posterolateral approach total hip joint replacement surgery teaching model. The posterolateral approach total hip joint replacement surgery teaching model comprises an acetabular model and a femoral model which cooperate with each other, wherein the outer ends of the acetabular model and the femoral model are each provided with a universal joint fixation end, the outer ends of the universal joint fixation ends are provided with magnets, the acetabular model and the femoral model are placed on a workbench, the workbench is provided with an upper fixation frame and a lower fixation frame, and the magnets are attached to the upper fixation frame and the lower fixation frame. The inner side of a skin model and the inner side of a subcutaneous tissue model are each provided with a scoreboard, and the inner side of a muscle tissue model is provided with a scoreboard. In a surgery process, first of all, skin and subcutaneous tissue are cut, the scoreboards are installed at the inner side of skin, the cutting position, angle and length can be detected, the surgery accuracy is evaluated, trainees are trained, and the surgery proficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of medical teaching equipment, in particular to a teaching model of posterolateral approach total hip replacement surgery. Background technique [0002] At present, according to the statistics of the National Bureau of Statistics of China, at the end of 2013, the total population of mainland China was 1,360.72 million, of which 202.43 million were 60 years old and above, accounting for 14.9% of the total population, and 131.61 million people were 65 years old and above, accounting for 9.7% of the total population . Beginning in 2013, the number of aging population in my country will increase by 10 million, and will double to 400 million in the next 20 years. A large number of elderly people suffer from hip disease. Total hip replacement is an ideal treatment option for end-stage hip diseases such as aseptic necrosis of the femoral head, severe hip osteoarthritis, femoral neck fracture, and DDH. According ...

Problems solved by technology

[0003] There is a huge patient population in joint replacement surgery, but the postoperative access is relatively high, and a professional title above the sub-senior level is required to operate independently. At the initial stage of the practice career, one can experience and master the essence of this surgical method. It is very important to invent a surgical training model that has the same anatomical structure as the normal human body, fully simulates the surgical process, and comprehensively evaluates and guides the entire surgical process. especially important
