The color indicator light can be a single-color indicator light or a multi-color indicator light, and a static luminous indicator light or a dynamic flashing indicator light can be selected. For example, the indicator lights that can generate different colors can be flashed, and the pressure is changed from strong to weak from red→yellow→green in sequence. The image indicator device can adopt multiple indicator lights, and the pressure change detected by the corresponding pressure detection component 4 is displayed by the number of the indicator lights that are lit.

The warning component 6 can be installed in any suitable position, for example, it can be installed on the side of the opening rod 2 away from the opening head 1 or on the opening handle 3, or it can be independent of the opening rod 2 and the side of the open-circuit head 1 and the open-circuit handle 3 exist. Preferably, the warning component 6 is mounted on the side of the opening rod 2 away from the opening head 1 and/or the opening handle 3 .

Since the warning component 6 needs to be installed in a place where the medical staff can see or hear, and when the nail path is established, the side of the open-circuit rod 2 away from the open-circuit head 1 and the open-circuit handle 3 It will not enter the patient's body, so the warning component 6 can be installed at any suitable position on the side of the open-circuit rod 2 away from the open-circuit head 1 and the open-circuit handle 3 .

When the present invention is in use, the medical personnel hold the open-circuit handle 3, align the open-circuit head 1 of the columnar structure 7 with the position where the nail path needs to be established in the patient, and push it slowly. The part of the open-circuit head 1 should be located in the bone and be blocked by the bone. The axial column 8 of the columnar structure 7 will move to the open-circuit handle 3 and squeeze the pressure detection part 4 when it is under greater pressure. When a relatively large pressure is detected, if the pressure detection part 4 is a spring pressure sensing part, it will retract, and the pressure information processing module 5 processes the pressure information detected by the pressure detection part 4, and compares the pressure. Normally, it should be greater than the preset If the pressure value is lower than the pressure value, the warning component 6 is not notified to warn the medical personnel, indicating that the nail path is established normally; when the open circuit head 1 and the part of the open circuit rod 2 close to the open circuit head 1 leave the normal position, the bone breaks through and enters the When the surrounding soft tissue is blocked by the surrounding soft tissue, the pressure detection part 4 detects a small pressure, and the pressure information processing module 5 processes the pressure information detected by the pressure detection part 4, and compares the pressure. Once it is less than the preset pressure value, Then notify the warning part 6 to warn the medical staff, indicating that the nail track has been deviated, so that the medical staff can adjust in time; , being blocked by the bone again, the pressure detection part 4 will detect a larger pressure again, and the pressure information processing module 5 processes the pressure information detected by the pressure detection part 4, and compares the magnitude of the pressure. Once it is greater than the preset pressure value, Then the control warning part 6 stops working, showing that the nail path is set up normally.

Therefore, the present invention detects the pressure received by the other end of the axial column of the columnar structure, that is, the open-circuit head, through the pressure detection part abutting against the end of the axial column of the columnar structure located in the open-circuit handle, and then judges by the pressure information processing module Whether an alarm is required, if the pressure is lower than the preset value, the warning component will be used to alarm, if the pressure is higher than the preset value, the warning component will not be used to alarm, so as to ensure that the nail path is established correctly, does not deviate, and avoids additional damage to the patient. even endanger the life of the patient.

Therefore, the present invention is novel in concept, simple in structure, and easy to use. The operator can adjust the direction in which the surgical device enters the bone according to the pressure information detected by the pressure detection components of each axial column, and establish the screw implantation channel for the fixed instrument, which can be compared Good protection of the safety requirements of clinical operations has greater application value.

To sum up, the real-time monitoring device for nail track establishment with a columnar structure of the present invention can monitor the nail track establishment process in real time.
