Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to an orthopedic nail extractor.

Background

The orthopedic instruments are specialized medical instruments specially used for orthopedic surgery, and are classified into the following parts according to the classification of the State food and drug administration: one type; the second and third types are mainly divided into an orthopedic knife, an orthopedic scissors, an orthopedic forceps, an orthopedic hook, an orthopedic needle, an orthopedic scraper, an orthopedic awl, an orthopedic drill, an orthopedic saw, an orthopedic chisel, an orthopedic file/shovel, an orthopedic active instrument and the like according to the use purpose and performance, and the fracture is one of the common diseases of bone trauma in medical clinic. The commonly used method for treating fractures is to perform internal fixation, i.e. after the fracture site is reduced, the reduced bones are connected by means of a bone plate and screws made of metal material.

At the in-process of taking out the screw, take out by the handheld apparatus of medical personnel more, nevertheless because the apparatus that medical personnel handed to easily lead to the screw rupture or get the nail apparatus because can't carry out steady fastening, and then lead to the patient to receive the secondary injury, and when using, have the device to remove inconvenient and adjust inconvenient problem.
