Positioning, opening and clamping device for minimally invasive total hip arthroplasty

Abstract

The invention discloses a positioning, opening and clamping device for minimally invasive total hip arthroplasty. The device comprises a bed body, wherein a head supporting pad, a hand positioning device, a body positioning device, a bone clamping device and a to-be-operated leg positioning traction device are arranged on the bed body. According to the device disclosed by the invention, the head,hands, body and legs of a patient can be respectively positioned by virtue of each device, so that the patient lies on the side on the hospital bed and keeps a comfortable posture, influences on operative procedures are avoided, the operated leg can be moved in a multi-directional manner, an operation panel can be connected to control the movement of the leg, and a doctor is easy to operate. Moreover, the total hip is easily taken out, the operation efficiency is improved, the operative complications are decreased, and wide popularization is facilitated.

Description

technical field [0001] The invention relates to medical equipment, in particular to a positioning, expanding and clamping device for minimally invasive total hip joint replacement surgery. Background technique [0002] According to statistics, at present, nearly 600,000 cases of artificial joint surgery are performed in Europe every year, and there are more than 300 million people in the United States. About 400,000 cases of artificial hip joint replacement surgery are performed every year, and about 500,000 cases of knee joint replacement are performed. my country is currently entering an aging society. The number of patients with osteoarthritis and femoral neck fractures alone has reached 50 million, and the number of patients receiving artificial joint replacement will increase year by year. According to calculations, the total number of potential primary artificial joint replacement plus revision surgery in China should be around 1.2 million to 1.7 million per year. [...

AI Technical Summary

Problems solved by technology

[0004] In the minimally invasive operation of total hip replacement, the patient needs to be fixed in a certain posture, and the position and angle of the legs need to be moved during the operation to facilitate the operation. The various parts of the patient need the assistance of an assistant when moving, and move to a certain position according to the doctor's requirements, so the current hospital bed is not convenient for the operation

Moreover, during the operation, the hip joint needs to be fully exposed. At present, there is no retraction and gripping device specifically for minimally invasive total hip replacement in clinical work. The whole process needs to be carried out by hand, which is inefficient and difficult to operate.
