Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic nail removal equipment, in particular to an orthopedic nail removal equipment for clinical use. Background Art

[0002] In orthopedic surgery, bone screws are often used to fix fractured bones. After the operation, when the bones have healed to a certain extent, the bone screws need to be removed to reduce the stimulation of the bone screws on the bones, promote local blood circulation, and thus promote further recovery of the remaining fracture healing sites; at the same time, it can reduce the discomfort caused by the bone screws remaining in the body and avoid long-term retention of the bone screws in the body causing infection, loosening, breakage or compression of surrounding tissues.

[0003] Currently, nail removal surgery typically uses two methods. The first involves hospital staff using a handheld nail remover, which is inefficient and difficult to operate. The second method involves mounting the nail remover on a bracket, which allows for manual operation without the need for handheld manipulation. However, the nail remover is typically fixed to the bracket and can only be moved vertically, preventing adjustment of the direction of removal. This results in the nail remover being unable to adapt to the position of the bone nail, making the removal process time-consuming and labor-intensive, and potentially increasing trauma. Therefore, it is necessary to develop an orthopedic nail removal device that can better adapt to the position of the bone nail. Utility Model Content
