A guide device for in-line hip replacement

Abstract

The invention discloses a direct insertion type guide device for hip replacement. The direct insertion type guide device comprises a handle, a guide connecting rod, an acetabular cup connector and a sleeve, wherein the lower end of the handle is connected to the acetabular cup connector; one end of the guide connecting rod is connected to one side, close to the upper end, of the handle, and the other end of the guide connecting rod is provided with a sleeve hole into which the sleeve is inserted; the acetabular cup connector comprises an installing shaft, the center shaft of the sleeve is approximately overlapped with the axis of the installing shaft, and the handle and the guide connecting rod are fixedly connected through a first insertion rod and a first socket matched with each other; the lower ends of the acetabular cup connector and the handle are fixedly connected through a second insertion rod and a second socket matched with each other. The guide device is easy to assemble and disassemble, and can be used for accurately locating, inserting and press-matching an acetabular prosthesis without dislocation.

Description

Technical field [0001] The invention relates to a minimally invasive hip joint replacement surgery tool, in particular to a direct insertion type hip joint replacement guide device. Background technique [0002] With the transformation of the new medical model to the bio-psycho-social medicine model and the formation of the overall treatment concept of surgical diseases, the development of minimally invasive surgery has been promoted. Mini-traumatic total hip replacement has only appeared in recent years. A new surgical method, which is based on the traditional total hip arthroplasty through the improvement of the surgical approach, operating methods and surgical tools, and completes the joint prosthesis in a relatively small incision (5-10cm) Body replacement requires the doctor's rich experience and the improvement of surgical instruments to obtain good surgical results. Therefore, higher requirements are put forward for the tools, which require a sufficient surgical field of ...

AI Technical Summary

Problems solved by technology

Therefore, minimally invasive total hip replacement surgery puts forward higher requirements for special and improved surgical tools, which can fully expose the acetabulum, prevent posterior dislocation, do not cut off muscles, retain a complete shutdown capsule, and accurately position, etc. Requirements, the current micro-trauma tools involved in the relevant patents have disadvantages such as complex use methods, difficult disassembly, or taking up a large space, and the existing tools cannot meet all requirements
