Problems solved by technology

[0002] Medical screws are internal fixation devices used to fix fractures. Due to the different types of medical screws, the size of the cross groove at the head of the medical screw is also different. When medical staff use traditional medical screw extractors, medical staff need to select The extractor that matches the cross groove of the medical screw is used to remove the screw from the patient's body. From the above, it can be seen that when the medical staff needs to remove screws of different types and sizes, at this time, the medical staff needs to carry a large number of different types of screws. device, which greatly affects the convenience of medical staff to carry medical equipment, in view of the above defects, it is necessary to design a medical screw extractor

Abstract

The invention discloses a medical screw extractor which comprises a sleeve body, a driving mechanism, a mounting groove, a moving mechanism, an extruding mechanism, a cross-shaped hole and a sliding mechanism. According to the medical screw extractor, medical personnel use the driving mechanism, and the driving mechanism drives the extruding mechanism to drive the sliding mechanism to perform adjustment treatment; in other words, the size of the adjusted sliding mechanism matches the size of a cross-shaped groove in the position where a screw needs to be taken out; screws of different types can be conveniently taken out of the body of a patient by the medical personnel through the device; the medical personnel can carry the device and use the device in cooperation with screws of differenttypes; and due to the device, the medical personnel can conveniently carry medical instruments.
