[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] The utility model realizes the removal of the harmonic clip by setting a thimble seat at the upper end of a fixed seat, setting a thimble at the upper end of the thimble seat, inserting the thimble seat into the inner part of a cylindrical groove when the harmonic clip needs to be removed. When inserting, two thimbles respectively apply upward forces to two harmonic clip bodies from bottom to top, so that the two harmonic clip bodies expand in two directions respectively, thereby realizing the opening of the harmonic clip by the thimble. At this time, the fixed seat is inserted into the inner part of the cylindrical groove, and the edge of the protruding seat is arc-shaped and is compressed into the adjusting groove when stressed. When reaching the buckle groove, after losing the extrusion force, the protruding seat is snapped into the buckle groove by the resilience of the compression spring, realizing the fixation of the sheath tube and the cylinder, and then the harmonic clip can be disassembled by pulling out the guide wire, solving the problem that after the existing harmonic clip is used, it is clamped on the tissue and waits to fall off automatically after the wound prognosis. Generally, the clip does not need to be removed, but there are often situations where it does not fall off after prognosis, or the clamping position is inappropriate and needs to be adjusted. In this case, the clip needs to be removed, but currently, this clip cannot be opened again after being clamped, and there is no corresponding tool to operate and open it. Usually, it is directly dragged and forcibly removed, causing secondary damage to the patient.

[0016] By arranging spring pressing plates at both ends of the compression spring, the two spring pressing plates are respectively clamped at both ends of the compression spring, between two spring coils. The two ends of the spring pressing plate with the spring pressing plate are respectively inserted into the first spring seat and the second spring seat. Two fixing screws respectively pass through the spring pressing plate first, and then pass through the first spring seat and the second spring seat respectively, and are fixed to the buckle plate and the fixed seat respectively. The spring structure is used to replace the existing elastic plate structure. When the elastic plate loses its elasticity, the entire fixed seat needs to be replaced. When the compression spring loses its elasticity, only the compression spring needs to be replaced, and the others do not need to be replaced, reducing the replacement cost.
