Abstract

The invention provides a femoral stem taking-out device and a femoral stem taking-out system. The femoral stem taking-out device is used for puling out the femoral stem inserted at the human femur from the human femur, and comprises a force transfer assembly and a force application part, wherein the first end of the force transfer assembly is connected with the femoral stem, and the second end of the force transfer assembly is a stopping end; the force application part is slidably arranged on the force transfer assembly, the force application part slides to the stopping end along the direction far away from the femoral stem and stops sliding, and the force transfer assembly transmits the force applied by the force application part to the stopping end to the femoral stem, so that the femoral stem is pulled out of the human femur. With the adoption of the femoral stem taking-out device and the femoral stem taking-out system, the problem that in the prior art, time and labor are wasted during the process of taking down the femoral stem at the human femur is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a femoral stem removal device and a femoral stem removal system. Background technique [0002] In the field of modern medicine, artificial hip replacement has appeared and been used for a long time. Artificial hip replacement mainly refers to the removal of lesions at the position of the human hip joint through medical equipment and then implanting an artificial hip prosthesis. So as to achieve the purpose of eliminating pain and improving the quality of life of patients. [0003] However, the artificial hip joint prosthesis implanted in the human body will wear or loosen during the long-term work, which will cause the patient to be unable to exercise and live normally. Body accuracy and stability. [0004] Hip revision requires the smooth removal of the femoral stem from the human femur, while ensuring that the human femur cannot be damaged in any way when the prosthes...
