Embodiment approach

[0026] As an embodiment of the present invention, a vibration motor 3 is fixedly connected to the outer side of the barrel 1, and a control button 31 is fixedly connected to the side close to the vibration motor 3 outside the barrel 1; 3. When it is difficult to unload the barrel 1, press the control button 31 to start the vibration motor 3. The motor of the vibration motor 3 drives the eccentric wheel to rotate, and the center mass of the eccentric wheel is not on the center of rotation of the motor, so that the motor is constantly out of balance. , Due to the vibration caused by the inertial action, the vibrating barrel 1 loosens the blockage, which facilitates feeding and improves the filling efficiency of the allogeneic bone powder.

[0027] As an embodiment of the present invention, a slide rail 32 is provided between the barrel 1 and the vibration motor 3, the slide rail 32 is fixedly connected with the barrel 1, and a slide block 33 is slidably connected to the slide rai...

Abstract

The invention belongs to the technical field of medical devices, in particular to an allogeneic bone filler device, comprising a material barrel; an end cover is threadedly connected to the top of the material barrel; , a screw plate is fixedly connected to the outside of the rotating shaft, and a hand wheel is fixedly connected to the top of the rotating shaft; the bottom of the barrel is provided with a feeding port, and the feeding port is threadedly connected with an extension pipe; Strip-shaped, when the diameter of the bone defect is small, the strip-shaped allogeneic bone needs to be crushed into pieces, and then filled in from the diameter of the bone defect by hand. Packing allogeneic bone by hand may be insufficient, and manual packing of allogeneic bone is often scattered. In the surrounding tissue, it is inconvenient to clean the scattered allogeneic bone; in the present invention, the extension tube is arranged to facilitate the filling of the allogeneic bone powder into the bone defect area, thereby solving the problems of insufficient packing and easy scattering when the diameter of the bone defect is small.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an allogeneic bone filler device. Background technique [0002] Allogeneic bone is one of the important ways to reconstruct bone defects after tumor resection. It is generally divided into structural bone grafting and filling bone grafting. Its advantages are: 1. Wide range of materials and unlimited dosage; 2. Structure similar to the patient's resectioned bone can be obtained during structural bone grafting; 3. Better function can be obtained after healing. [0003] For example, a Chinese patent with application number CN201510458000.0 discloses a bone cement mixing and bolus injection system, which is mainly composed of a screw handle, a bone cement mixer, a bone cement injection cylinder and a bone cement outlet pipe; The stirring channel part is provided with a stirring movable part inside the stirring channel part, and the stirring movable part is slidably connecte...
