Position fixation device for preoperative position fixation of patients accepting hip joint and knee joint operations and using method of position fixation device

Abstract

The invention discloses a position fixation device for preoperative position fixation of patients accepting hip joint and knee joint operations and a using method of the position fixation device. Theposition fixation device comprises a bed board and limiting rods, wherein inserting holes, in which the limiting rods can be inserted and fixed, are distributed in the bed board; the inserting holes in the width direction of the bed board, which keep the longest distance, keep an occupied width which can at least accommodate a human body under a lateral position; and the distribution density of the inserting holes in the bed board is such designed that the limiting rods which are inserted are adjustable in distance therebetween. According to the position fixation device provided by the invention, on the basis of cooperation between the bed board provided with the inserting holes and U-shaped pedal rods and the limiting rods, a good assisted fixation effect can be achieved on keeping a lateral position in a hip joint surgery and on leg buckling in a knee joint surgery, so that the quantity of surgery assistants is reduced, labor intensity of the surgery assistants is reduced and a problem of errors in the hip joint and knee joint surgeries is relieved; meanwhile, an operating space of surgeons is widened; the device is simple in structure and convenient to operate; and two functionsof conducting the hip joint and knee joint surgeries on a same board can be achieved.

Description

Technical field [0001] The present invention relates to the field of medical surgical auxiliary instruments, in particular to a posture fixation device that can be used for preoperative posture fixation of patients undergoing surgery on hip and knee joints and a method of use thereof. Background technique [0002] During knee surgery, especially during total knee replacement surgery, it is often necessary to maintain the knee flexion at 90° or extreme flexion according to the operation. However, because the foot is easy to slide, or the patient cannot get well The support in this way affects the flexion state, resulting in inconvenience or accuracy of the operation; and during hip surgery, it is often necessary to maintain the patient's standard lateral position. Also, the patient cannot maintain a stable standard side due to the lack of good support. The lying position affects the progress and results of the operation, especially in total hip replacement surgery. The angle of th...
