Problems solved by technology

Nowadays, with the advancement and development of science and technology, joint replacement surgery has become a hot spot for many patients. When we perform joint replacement surgery, it is necessary for the doctor to manually clamp the prosthesis, and then adjust the angle to find the correct installation position to avoid the occurrence of The distal end of the prosthesis is cracked after implantation, but the tool for clamping the prosthesis is likely to cause friction damage to the soft tissue of the human body as the position is adjusted; and in the process of hitting the implanted prosthesis, vibration is inevitable, which often brings us Inconvenience

Abstract

The invention discloses a condyle holder for prosthesis implantation, which comprises a rotating rod, a femur extractor support body, a hook, a clamping block, claws, a lead screw, and a limit block. Composed of a rod head and a rotary rod column, the rotary rod head is fixedly connected with the rotary rod column, the rotary rod column passes through the interior of the femoral extractor support body and is connected to the limit block through the first bolt assembly, and one end of the hook The second bolt assembly is connected to the lower end of the femoral extractor support body, the other end of the hook is clamped to the middle position of the screw, the two sides of the middle position of the screw are provided with reverse threads, and one end of the screw is provided with a rotating handle , the reverse threads on both sides of the middle position of the lead screw are respectively screwed with the clamping block, the clamping block passes through the transverse groove of the femoral extractor support body, and the clamping block is connected with the upper end of the claw , the two claws are respectively fixed on both sides of the limit block. The condyle holder has the advantages of being convenient to adjust the installation position of the prosthesis and improving the stability of the prosthesis during operation.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, specifically to a condyle holder that facilitates implantation of a prosthesis. Background [0002] Artificial joint replacement, a kind of metal, polymer polyethylene, ceramics and other materials, according to the shape, structure and function of human joints to make artificial joint prostheses, implanted in the human body through surgical technology, instead of diseased joint function, to achieve the purpose of relieving joint pain and restoring joint function. Nowadays, with the advancement and development of science and technology, joint replacement surgery has become a hot spot for many patients, when we carry out joint replacement surgery, we need to manually clamp the prosthesis through the doctor, and then adjust the angle to find the installation position, to avoid the occurrence of distal cracking after implantation of the prosthesis, but the tool to clamp the prosthesis is ...
