Joint prosthesis with anti-dislocation structure

Abstract

The joint prosthesis comprises a front bone handle and a connecting rod, a front bolt is installed at the bottom of the front bone handle, a femoral stem is installed on the outer side of the front bolt, a supporting plate is installed in one end of the femoral stem, a head bolt is installed at the top of the front bone handle, a femoral head is installed at the top of the head bolt, and a positioning pin is installed at the bottom of the femoral head. A plastic lining is installed on the outer side of the top of the femoral head, and a connecting rod is installed on the top of the plastic lining in an embedded mode. Through the installed connecting rod, the connecting rod can provide the effect of connecting the anti-disengagement ball with the femoral head, the connecting rod can be matched with the anti-disengagement ball and the anti-disengagement lining, the effect of preventing the femoral head from disengagement is achieved, and the anti-disengagement lining and the anti-disengagement ball can also achieve the effect of moving together with the femoral head while achieving the anti-disengagement effect; the joint prosthesis can be normally used when having an anti-dislocation function, and convenience can be provided for a patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a joint prosthesis with an anti-dislocation structure. Background technique [0002] Joint prosthesis is one of the indispensable devices in the medical field. With the rapid development of today's society and the continuous progress of science and technology, the use of joint prosthesis in medicine is becoming more and more frequent, and joint prosthesis replaces patients. The original joint, and a joint prosthesis with an anti-dislocation structure can provide convenience and personal safety for the patient. [0003] The disadvantages of existing joint prostheses are: [0004] 1. The traditional joint prosthesis has no facility to effectively prevent the dislocation of the prosthesis, which makes the dislocation of the joint prosthesis after the installation is completed. [0005] 2. Traditional joint prostheses do not have facilities for real-time detection of the pa...

AI Technical Summary

Problems solved by technology

[0004] 1. The traditional joint prosthesis has no effective facilities to prevent the dislocation of the prosthesis, which makes the dislocation of the joint prosthesis become very common after the installation is completed, which makes the patient's personal safety very unfavorable and troublesome.

[0005] 2. The traditional joint prosthesis does not have the facility to detect the physical condition of the patient after the prosthesis is installed in real time within a certain period of time, so that doctors and patients cannot observe in real time whether there is any adverse reaction after the prosthesis is installed
