TISSUE CLAMPING AND CLOSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/022905
Kind Code:
A1
Abstract:
A tissue clamping and closing device, comprising: an operation assembly (1) and a clamp head assembly (2). In practical application, an operation wire (4) in the operation assembly (1) may drive an elastic release piece (11) to move so that a clamp (21) in the clamp head assembly (2) may slide in a sleeve (22), and the clamp (21) may be opened and closed multiple times by means of the self-elasticity of the clamp (21) and the wall function of the sleeve (22). By means of the restriction and restriction release of the inner wall of the sleeve (22) for the elastic release piece (11), a separable connection of a groove in the middle of the clamp (21) to connection parts at the far end of the elastic release piece (11) is achieved. The tissue clamping and closing device is simple in structure, stable in connection and is easy to fabricate stably and in batch, and the production process costs and the quality control costs are greatly reduced.
