Allogeneic bone filler device

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an allogeneic bone filler device which comprises a charging barrel. The top of the charging barrel is in threaded connection with an end cover, the center in the charging barrel is rotationally connected with a rotating shaft, the rotating shaft is rotationally connected with the end cover, the outer side of the rotating shaft is fixedly connected with a spiral plate, and the top end of the rotating shaft is fixedly connected with a hand wheel; a discharging opening is formed in the bottom of the charging barrel, and the discharging opening is in threaded connection with an extension pipe; in the prior art, clinical common allogeneic bones are long-strip-shaped, when the aperture of a bone defect is small, the strip-shaped allogeneic bones need to be smashed into powder, then the powder is filled into the aperture of the bone defect by hands, the allogeneic bones are possibly insufficiently filled by hands, meanwhile, the allogeneic bones are often scattered in surrounding tissues when the allogeneic bones are manually filled, and the scattered allogeneic bones are inconvenient to clean; according to the device, by arranging the extension tube, allogeneic bone powder can be conveniently filled into a bone defect area, and therefore the problems that filling is insufficient and scattering is likely to happen when the bone defect caliber is small are solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an allograft bone filler device. Background technique [0002] Allograft bone is one of the important ways to reconstruct bone defect after tumor resection, and it is generally divided into structural bone graft and filling bone graft. Its advantages are as follows: 1. A wide range of materials can be obtained, and the dosage is not limited; 2. The structure similar to that of the patient's resected bone can be obtained during structural bone grafting; 3. Better functions can be obtained after healing. [0003] For example, a Chinese patent with the application number CN201510458000.0 discloses a bone cement mixing and injection system, which is mainly composed of a screw handle, a bone cement mixer, a bone cement injection cylinder and a bone cement outlet tube; Stirring channel parts, stirring movable parts are arranged inside the stirring channel parts, and the stirri...
