AI Technical Summary
The existing hemostatic clips have a flat clamping surface, which leads to unstable clamping and cannot effectively block blood flow.
Two rotating clamping plates are designed. Multiple parallel protrusions and ridges are provided on the inner side of the clamping plates. Stable clamping is achieved by the elastic force of the elastic component. The protrusions on the clamping plates interlock to enhance clamping stability, and the compression effect is improved by the ridges on the other clamping plate being squeezed by the ridges on the other clamping plate.
It achieves stable clamping of blood vessels, effectively blocking blood flow, and can adapt to blood vessels of different diameters, improving the flexibility and stability of clamping.
