The body position adjusting system for direct anterior approach in minimally invasive total hip arthroplasty

Abstract

The invention relates to a body position adjusting system for a direct anterior approach in minimally invasive total hip arthroplasty. The body position adjusting system comprises an intelligent digital pneumatic pump power device and a body position air bag device. The body position air bag device is connected to the intelligent digital pneumatic pump power device through an air pressure transmission line. The body position air bag device is inflated and deflated by controlling the intelligent digital pneumatic pump power device. The body position air bag device comprises an air bag switcherand air cushions. The air cushions are divided into two types, namely an acetabular sacroiliac joint adjusting air cushion and a proximal femur adjusting air cushion. The air bag switcher is arrangedbetween the intelligent digital pneumatic pump power device and the body position air bag device. The air bag switcher is connected with individual independent air cushions in the body position air bag device and used for inflating or deflating different air bags according to the operation side and the position needing to be lifted or lowered during the operation. According to the body position adjusting system, the heights of the acetabular side and the proximal femur can be adjusted at any time according to the requirement for the body position in an operation, thereby facilitating surgicaloperation.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a body position adjustment system applied in direct anterior approach minimally invasive total hip replacement. Background technique [0002] Direct anterior approach minimally invasive total hip arthroplasty conforms to the concept of minimally invasive and rapid recovery surgery, and is gradually recognized by more surgeons. Make a good exposure at the end and reduce the damage to the patient due to poor exposure, as follows: [0003] 1. When dealing with the acetabular side, it can raise the acetabulum and sink the proximal end of the femur at the same time. Raising the acetabulum can easily fully expose the deep acetabulum, and it is convenient to place the acetabular file for grinding the acetabular fossa. Good Accurately control the anteversion and abduction angles of the acetabular reamer, which is conducive to more accurate installation of the prosthesis; [0...

AI Technical Summary

Problems solved by technology

[0012] ① In terms of anesthesia management, the use of large doses of muscle relaxants will cause more harm to the patient's body, including affecting cardiopulmonary function and increasing the burden of liver and kidney metabolism, especially for elderly patients, increasing the risk of anesthesia management

A large number of muscle relaxants will significantly delay the patient's recovery from anesthesia, and the long-term anesthesia state will bring more damage to the patient's body

[0013] ②In terms of the design and use of special surgical instruments, although the operation and the instrument manufacturer have carried out special design and improvement of the instruments according to the specific operation of the direct anterior approach minimally invasive total hip arthroplasty, for some patients with special constitutions, such as obesity or Strong patients still need to use violen
