Abstract

The invention belongs to the technical field of medical equipment, and concretely relates to a nail taking device for orthopedics, existing screw taking modes are mostly used through screwdrivers, thescrews often fall off, during twisting, the screw is stressed unevenly and is capable of easily slipping, proposed now is the following scheme, the device comprises a transverse plate, a threaded rodis in threaded connection with the central position of the transverse plate; the bottom end of the threaded rod is connected with a screw head; two telescopic legs are symmetrically mounted at the bottom of the transverse plate in a sliding manner; supporting legs are slidably mounted on the outer sides of the two telescopic legs correspondingly, two welding rods are fixedly mounted at the bottomof the transverse plate, the same welding plate is fixedly mounted at the bottoms of the two welding rods correspondingly, the threaded rod is in threaded connection with the welding plate, two adjusting holes are symmetrically formed in the welding plate, and two transverse supporting rods are transversely and fixedly mounted in the two adjusting holes correspondingly. According to the screw taking device, screws can be clamped during screw taking, the screws are prevented from falling off, and the screw taking device can adapt to screws of different sizes.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a nail removing device used in orthopedics. Background technique [0002] In orthopedic treatment, the fracture site is usually connected with a steel plate, and the steel plate connection needs to be fixed with screws. When performing bone fixation recovery treatment for patients with fractures and bone fractures, the steel plate needs to be removed. It is necessary to remove the steel plate and remove the nails. of. [0003] The existing nail removal methods are mostly used by a screwdriver, which often causes the screw to fall off, and the screw is unevenly stressed when twisted, and it is easy to slip off. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings that the existing screwdriver is often used for removing screws, and the screws often fall off, and the screws are unevenly stressed during twisting, and are ea...
