Abstract

The invention provides a prosthesis extractor, a broach extractor and a prosthesis extraction device. The prosthesis extractor is characterized by comprising: a rod body, wherein the two opposite ends of the rod body are the near end and the far end respectively; an electric drill connector for being connected with an external electric drill, wherein the electric drill connector is arranged at the near end; and a cutter head for rotating at a prosthesis part to be taken out so as to cut the prosthesis part to be taken out, wherein the cutter head is arranged at the far end. According to the prosthesis extractor the broach extractor and the prosthesis extraction device provided by the embodiment of the invention, the prosthesis extraction time can be shortened, the damage to the to-be-extracted prosthesis part of a patient is reduced, and the patient can recover as soon as possible.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a prosthesis extractor, a medullary needle extractor and a prosthesis extractor. Background technique [0002] Several years after the prosthesis is implanted in the body, some patients will experience prosthesis fracture. Taking the medullary needle as an example, after the fracture of the prosthesis, the cross section of the prosthesis is flush with the bone interface, especially the bio-type fixed prosthesis, the prosthesis is integrated with the patient's own bone, so the prosthesis can be removed without damage Own bone problems have always plagued medical workers. In the related art, there is no special tool for removing the broken medullary needle. Generally, a bone knife or bone warp combined with forceps is needed to remove the marrow needle. This method of using a bone knife or bone warp to remove the prosthesis will cause The patient's bone destruction is rel...
