Auxiliary device for orthopedic joint replacement surgery

Abstract

The invention discloses an auxiliary device for orthopedic joint replacement surgery, and belongs to the field of orthopedic medical instruments. The auxiliary device comprises a long tube, a cleaning disc communicated with the long tube is mounted at the front end of the long tube, a rotating shaft and a spiral blade conveyor are rotatably mounted in the long tube and the cleaning disc,the spiral blade conveyor is mounted on the surface of the rotating shaft in a winding manner, a motor fixed to the long tube is installed at the rear end of the long tube, the rear end of the rotating shaft and a driving shaft of the motor are installed, a protective blocking piece is installed on the front side in the cleaning disc, a plurality of through holes are formed in the protective blocking piece, and the front end of the rotating shaft and the center of the protective blocking piece are rotationally installed. The device can conveniently and rapidly clean and collect bone residues and blood at an operation part, so that the operation view is better guaranteed, medical staff can conveniently perform an operation, the device is simple in structure, the operation process is rapid, the cleaning effect is good, the time occupied by cleaning operation in the operation is greatly shortened, and the operation can be smoothly performed.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to an auxiliary device for orthopedic joint replacement surgery. Background technique [0002] Femoral head necrosis is a disease in which the blood supply to the femoral head is interrupted or damaged, resulting in the death and subsequent repair of bone cells and bone marrow components, which in turn leads to structural changes in the femoral head, collapse of the femoral head, and joint dysfunction. Femoral head replacement surgery needs to remove the necrotic femoral head and then install the prosthesis. The femoral head prosthesis needs to be fixed by screws, so it is necessary to drill holes in the human bone. [0003] For example, Chinese Patent No. CN 109805983 B discloses an orthopedic joint replacement surgical device, which includes a host housing, a speed control device is provided on one side of the outer surface of the host housing, and a handle is f...

AI Technical Summary

Problems solved by technology

[0004] When drilling human bones, a large amount of bone residue will be produced. The bone residue mixed with blood and broken tissues will block the surgical site and reduce the surgical field of view. The cleaning operation of the bone residue and blood by medical staff is relatively slow, which prolongs the operation time and is not conducive to the smooth progress of the operation. Therefore, the present invention proposes an auxiliary device for orthopedic joint replacement surgery.
