[0030] Embodiment
[0031] When performing an operation, first tie a traction wire in the clamping opening of the traction clip body 6, then sleeved the detachable end 2 on the tube sleeve 1. At the same time, the operating wire 10 is inserted into the limiting end 7, and the limiting protrusion 11 is used to prevent the limiting end 7 from coming off. After completing the above steps, the tube sleeve 1 is directly inserted into the patient's affected area from the surgical tube. Then the clamping opening of the traction clip body 6 is located at the affected area. Then pull the operating wire 10. The operating wire 10 drives the limiting end 7 to move. The limiting end 7 drives the wire pulling mounting table 8. The wire pulling mounting table 8 drives the wire pulling mounting frame 9. The wire pulling mounting frame 9 drives the wire 12. The wire 12 drives the upper clip body 15 and the lower clip body 16, so that the clamping opening of the traction clip body 6 is closed. The tooth structure 14 on the traction clip body 6 can pierce into the affected tissue of the patient to form a firm connection. After completion, pull the operating wire 10 again. Under the action of the limiting ribs 18, the operating wire 10 and the limiting end 7 are separated. At the same time, under the action of the clamping ribs 20, the limiting end 7 remains stationary, so that the clamping opening of the traction clip body 6 can always be in a closed state. According to the overall volume of the affected tissue of the patient, multiple traction clips can be implanted according to the original operation. After completion, the affected part of the patient is resected. In order to facilitate the surgical resection, the tube sleeve 1 can be taken out. After the resection of the patient is completed, the cut affected tissue is pulled out of the patient's body through the traction wire. The clamping firmness of this device is high, and the phenomenon of the traction clip body 6 slipping off is avoided.
