[0002] In orthopedic surgery, it is often necessary to pass a Kirschner wire through the skin and soft tissue through a bone block and then drill into another preset bone block for fixation. During the operation, due to the long length of the Kirschner wire and a slight deviation in the drilling direction, the final drilling position will have a large deviation and cannot reach the expected position. Currently, when encountering this situation, the doctor will use a tool to move the Kirschner wire in the surgical incision to deflect the tip of the Kirschner wire in the preset direction and then continue drilling; because in most cases the deviation is within a few millimeters and the Kirschner wire has good elasticity, the accuracy of puncture is low.
