Description

Technical Field

[0001] The utility model relates to the technical field of split closing clips, in particular to an assembly structure of a split closing clip and an applicator forceps. Background Art

[0002] A closing clip is a clip for identifying and clamping blood vessels or duct tissues in a surgical operation (especially a laparoscopic operation). It usually has upper and lower arms. One ends of the two arms are connected to form a V shape, and the other ends can be locked and fixed after clamping. In the prior art, in order to make the closing clip absorbable and have all the clamping performances of a non-absorbable clip, a split closing clip is made of an absorbable biomaterial. However, since the split closing clip has no elasticity, there must be a good fixing and de-clamping assembly structure for assembly during use between the applicator forceps and the split closing clip, so as to avoid the high-cost use condition that the closing clip and the applicator forceps need to be pre-assembled during production, and when the closing clip is used up, the remaining applicator forceps are discarded. Summary of the Utility Model

[0003] The present application aims at the above-mentioned disadvantages in the existing production technology, and provides an assembly structure of a split closing clip and an applicator forceps with a reasonable structure. The split closing clip can be quickly assembled with the applicator forceps during use, thus ensuring that the split closing clip can be properly stored alone on the shelf without pre-assembly.

[0057] The split closing clip of the utility model can be quickly assembled with the clamping forceps when in use, ensuring that the split closing clip can be properly stored separately when not in use, and also enables the clamping forceps to be repeatedly used, reducing the cost of use; the connection structure of the split closing clip and the clamping forceps is convenient for quick assembly, and is also convenient for the closing clip to be separated from the clamping forceps after closing, improving the convenience of operation. The two arms of the split closing clip of the utility model are made separately and connected and combined together by a hinge structure. There is no elastic effect between the two arms, and it is impossible to achieve the same top support connection as the clamping forceps by relying on its own elasticity (top support connection means that the two arms of the closing clip are firmly supported in the jaws of the clamping forceps with the strong elasticity of the opening of the closing mouth, and can open and close with the jaws without losing the clamp. After the closing clip is closed and locked, the external support elastic force disappears, and the clamping forceps opens at this time, and the closing clip is separated from the clamping forceps to achieve the clamping.) Instead, the opening and closing, clamping, and clamping functions of the closing clip need to be handed over to the clamping forceps (such as patent CN116158803A) to complete.
