Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a nail remover. Background Art

[0002] In clinical medicine, fracture is one of the common diseases of bone trauma. The commonly used method for treating fracture is to perform internal fixation surgery, that is, after the fracture site is reduced, the reduced bones are connected with the help of bone plates and screws made of metal materials. During the internal fixation and the process of removing the bone plates after surgery, the screws need to be removed. Due to various reasons, the screws are often broken, and it is difficult to unscrew the screws with tools such as screwdrivers. The process of removing the screws is time-consuming and laborious, and it is easy to increase trauma and operation time. Even giving up the removal of the nails, leaving them in the bones for life, brings many inconveniences to patients.
