Curette for orthopedics department

Abstract

The invention discloses a curette for the orthopedics department. The curette comprises a curette bottom plate, curette side plates are rotationally connected to the three side walls of the curette bottom plate through rotating assemblies, each rotating assembly comprises a rotating cylinder and a rotating rod, a plurality of elastic torsion rods are fixedly connected between the rotating rod and the inner wall of the rotating cylinder, the rotating rod is at least fixedly connected with a pull rope, the pull ropes are at least movably wound around the rotating rod for half a circle, an adsorption space is formed in the curette bottom plate, and the end, stretching into the adsorption space, of a connection rope is fixedly connected with an elastic adsorption plate. During use of the curette, pathological tissue of a patient is scraped through overturn of the curette side plates, which not only expands the range of curettage, but also improves the efficiency of curettage; and the adsorption space comprising a first adsorption cavity, a second adsorption cavity and an extrusion cavity is formed, the elastic adsorption plate is further arranged in the adsorption space, and adsorbs blood in the adsorption cavities and discharges the blood in the extrusion cavity, so that the blood is pumped and removed, and the situation that the blood flows randomly and contaminates an operation environment is avoided.

Description

technical field

[0001] The invention relates to the technical field of orthopedic surgical instruments, in particular to an orthopedic curette. Background technique

[0002] When performing intraosseous implantation surgery, it is generally necessary to use a bone curette to scrape off bone tuberculosis and bone lesion tissue, and remove the scraped bone residue and necrotic tissue from the wound, and then perform intraosseous implantation. But the traditional bone curette is inconvenient to take out the scraped bone residue and excess tissue after scraping the bone residue and diseased tissue.

[0003] In the prior art, a bone curette with the application number "201811480005.3" includes a handle and a spoon body, the spoon body is provided with a concave surface, the concave surface defines the first groove and forms the inner surface of the first groove, the first groove The bottom wall and / or side wall of the bottom wall is provided with a first through hole, which faci...
