Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bone nail remover. Background Technology

[0002] With the continuous development of technology, medical standards have also improved. For example, orthopedics has evolved from simply treating fractures later in their course with external fixation to directly fixing the bone with plates for more severe fractures. Therefore, when a fracture occurs, open reduction and internal fixation or external fixation are commonly used. Internal fixation uses plates, screws, intramedullary nails, and other instruments to fix the fracture ends, allowing them to heal in the correct position. External fixation uses external fixation devices to fix the fracture site from outside the body, and is suitable for some complex or open fractures, achieving better rehabilitation.

[0003] After bone healing and rehabilitation, the steel plates and nails in the body need to be removed. However, the position and angle of the nails in some special locations are different, and they need to be removed according to the specified position. Currently, the limb is simply laid flat. However, because the steel nails are located at specific angles in the limb, the limb needs to be reinforced and the specified support adjusted, which makes the removal of the steel nails difficult.
