Auxiliary device for hip joint replacement operation

Abstract

The invention relates to an auxiliary device for hip joint replacement operation. The device comprises a bedstead and a bed plate, wherein the middle part of the top end of the bedstead is provided with a buttocks-supporting plate which can move back and forth and lift; the left and right sides of the bedstead are respectively and slidably connected to sliding plates capable of sliding forwards and backwards, the top end of each sliding plate is hinged to a working plate, the bottom of each working plate is provided with leg supporting rods with adjustable height, the inner sides of the working plates are provided with jacking plates capable of moving leftwards and rightwards and inclining forwards and backwards, and the top end of each jacking plate is provided with a push plate and a folding plate which can independently adjust the inclination angle and are hinged to each other; and the left and right sides of the rear end of the bedstead are hinged to telescopic lifting plates, thetop ends of the lifting plates are hinged to bridge plates, the inner ends of the two bridge plates are movably connected and slidably connected to a moving plate, a rotating plate capable of horizontally rotating and moving up and down is arranged on the moving plate, and two leg lifting clamps hinged to each other are arranged at the bottom end of the rotating plate. The device effectively solves the problems that: the body position cannot be changed in the prior hip joint replacement operation, the body position of a patient cannot be firmly fixed in the operation, and the part to be operated cannot be fully exposed.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an auxiliary device for hip joint replacement surgery. Background technique [0002] Hip joint replacement, also known as artificial hip replacement, is to fix the artificial prosthesis, including the femoral part and the acetabular part, on the normal bone with bone cement and screws to replace the diseased joint and reconstruct the normal state of the patient's hip joint. Features. During hip replacement surgery, the patient's position needs to be stabilized and fixed to adapt to the vibration and shaking of various operations such as bone removal, acetabular cleaning, and drilling during hip replacement. At present, there are two kinds of body positions for hip replacement, which are generally determined according to different incisions: 1. When using the posterolateral incision, the patient lies on his side with the affected side on top. 2. A lateral or anterolateral inci...
