The detected pressure information is compared and the pressure is compared. Once it is less than the preset pressure value, the warning component 6 will be notified to warn the medical staff, indicating that the establishment of the nail path has deviates, so that the medical staff can adjust in time; The part of the open-circuit rod 2 close to the open-circuit head 1 returns to the bone, and is blocked by the bone again, and the movable body 7 is subjected to greater pressure, and the pressure detection component 4 will detect the greater pressure again, The pressure information processing module 5 processes the pressure information detected by the pressure detection component 4, and compares the magnitude of the pressure. Once the pressure is greater than the preset pressure value, the warning component 6 is controlled to stop working, indicating that the nail road is established normally.

Therefore, the present invention detects the side protruding from the open head and/or the open rod close to the open head by abutting against the pressure detection member located at the other end of the movable body in the open head body. Then the pressure information processing module judges whether an alarm is required. If the pressure is lower than the preset value, it will alarm through the warning component.
