Abstract

The invention provides a bone fixation nail taking-out device and a bone fixation nail taking-out system. The bone fixation nail taking-out device is used for pulling out a bone fixation nail nailed in the bone, and comprises a barrel body and a locking and drawing assembly, wherein the barrel body is provided with a cavity; the locking and drawing assembly is glidingly arranged on the barrel body in a direction of an axis of the cavity and used for locking the bone fixation nail and driving the bone fixation nail to move in a direction away from the bone. With the adoption of the device and the system, the problem that time and labor are consumed when the bone fixation nail nailed in the bone of a human body is pulled out by an orthopedic nail puller in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone fixation nail removal device and a bone fixation nail removal system. Background technique [0002] In the field of modern medicine, artificial joint replacement has appeared and been used for a long time. Artificial joint replacement mainly refers to the removal of lesions at the joint position of the human body through medical equipment and then implanting artificial joint prosthesis, so as to eliminate the pain and improve the patient's quality of life. [0003] During artificial joint replacement, in order to better match the artificial joint prosthesis with the patient's own bones and improve the movement flexibility of the artificial joint prosthesis in the patient's body, it is usually necessary to perform osteotomy on the patient's bone with lesions , in the process of osteotomy, bone fixation nails need to be used to position and fix the patient's bones, ...
