Document Type and Number:
WIPO Patent Application WO/2017/156649
Kind Code:
A1
Abstract:
Disclosed a disposable digestive tract soft tissue clamp, belonging to the field of medical instruments. The disposable digestive tract soft tissue clamp is provided with a handle, a delivery mechanism, a hook (4) and a release mechanism, wherein the release mechanism comprises a metal clamp (1) and a tightening barrel, the metal clamp (1) being provided with an arc-shaped root (11) and a pair of clamping jaws (12) extending forwards from the arc-shaped root (11), and extending arms of the clamping jaws (12) being in a crosswise arrangement; and an inner wall of the tightening barrel is provided with a circle of protrusions (31), the arc-shaped root (11) of the metal clamp (1) is located at the front end of the tightening barrel, and the tail end of the hook (4) stretches into the tightening barrel from the back end of the tightening barrel and is connected to the arc-shaped root (11) of the metal clamp (1). The hook (4) drives the metal clamp (1) to move into the tightening barrel to enable the clamping jaws (12) of the metal clamp (1) to be closed, the arc-shaped root (11) of the metal clamp (1) enters the tightening barrel and passes through the protrusions (31), and the protrusions (31) tightly wrap around the metal clamp (1) to prevent the metal clamp (1) from being disengaged towards the front end of the tightening barrel to be opened. The head end of the hook (4) is connected to the conveying mechanism, thereby omitting the glue filling operation and enabling the assembling technology of the disposable digestive tract soft tissue clamp to be simpler.
