Problems solved by technology

[0002] In the reconstruction of the extensor tendon insertion, the medical screwdriver is used to implant the threaded anchor into the bone. The medical screwdriver in the prior art includes a screwdriver body and a handle. The upper end of the screwdriver body is connected with the handle, and the lower end is provided with a seam Thread groove, during operation, the suture passes through the threading hole on the anchor with thread and enters the thread groove at the lower end of the screwdriver body, and the lower part of the driver body extends into the hole groove on the upper surface of the anchor with thread, and then turns the screwdriver to tighten the anchor with thread The nail is implanted into the bone. When the anchor with thread is implanted into the bone, the suture passes through the suture groove at the lower end of the driver body, allowing one person to hold the suture and the driver at the same time, which saves manpower, but because the suture penetrates into the driver body Therefore, when the screwdriver is turned, the suture is easy to wrap around the screwdriver body, which has increased the complexity of the operation
