[0043] Instructions for use: In the initial state, under the elastic force of the supporting spring assembly 3, the handle is in the open state, i.e. Figure 1 The state is shown. The titanium clip is placed between the moving rotor 16 and the stationary rotor 11. When the handle is closed, the supporting spring plate assembly 3 deforms and the elastic force gradually increases. The upper end of the front handle 1 moves forward, pushing the push rod assembly 6 forward, causing the fixed clamp head 7 to rotate downward. The titanium clip deforms and clamps onto the broken end of the blood vessel. Depending on the needs near the blood vessel, if flushing is required, the flushing connector 9 is connected to the flushing equipment, and flushing water flows out from the front end of the outer tube 5.

[0044] Depending on the surgical situation, if it is necessary to change the clamping angle of the fixed clamp head 7 and the movable clamp head 8 around the axis of the outer tube 5 in order to better operate the titanium clip to the blood vessel, one hand continues to hold on the handle, while the index finger is placed on the pull rod 26. Tighten the pull rod 26, and the pull rod 26 will drive the chuck head 23 away from the positioning wheel 21 through the bracket 24. The other hand can then rotate the rotating wheel assembly 4 until the fixed clamp head 7 and the movable clamp head 8 are rotated to the required angle. Then release the pull rod 26. Under the action of the tension spring 25, the chuck head 23 re-enters the chuck head 22 in the chuck groove 22 of the positioning wheel 21, and the rotating wheel assembly 4 is fixed, and the angle of the fixed clamp head 7 and the movable clamp head 8 is fixed.

[0045] Depending on the surgical situation, if it is necessary to change the clamping angle of the fixed clamp head 7 and the movable clamp head 8 relative to the plane where the handle is located, simply rotate the fixed clamp head 7 and the movable clamp head 8. The guide rod 20 ensures that the fixed clamp head 7 and the movable clamp head 8 always rotate synchronously, preventing the fixed clamp head 7 and the movable clamp head 8 from becoming misaligned and causing the titanium clamp to slip off.
