Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an easy-to-operate orthopedic nail removal device. Background technique [0002] During orthopedic surgery, it is often necessary to connect the broken bones together with steel plates and fix them with bone nails. After healing, the bone nails are pulled out to remove the steel plates. [0003] When using the existing screwdriver, insert the screw rod on the screwdriver into the nail groove on the bone screw cap, hold the first handle and rotate it, and drive the screw rod to rotate to take out the bone screw. After a long time of taking the nails, the palms of the operator are prone to sweating, which will cause the hands to slip when holding the first grip, resulting in inconvenient operation, delaying the time of taking the nails, and adding pain to the patient during the nail removal process. We propose an easy-to-operate orthopedic nail removal device. ...
