Title:
METHOD FOR DRIVING CLIP BIN SHAFT OF CLIP APPLIER AND CLIP APPLIER
Document Type and Number:
WIPO Patent Application WO/2022/057732
Kind Code:
A1
Abstract:
A clip applier, wherein a driving shaft (11) of the clip applier and a clip bin shaft (21) located at an initial position of a proximal end of the clip bin shaft forms a separable connection under the action of an axial external force, the driving shaft (11) pushes the clip bin shaft (21) to move from the initial position of the proximal end of the clip bin shaft to an end position of a distal end of the clip bin shaft, and after the clip bin shaft (21) leaves the initial position of the proximal end of the clip bin shaft, the driving shaft (11) and the clip bin shaft (21) are locked and remains in a locked state; and the driving shaft (11) drives the clip bin shaft (21) to move from the end position of the distal end of the clip bin shaft towards the direction of the proximal end, and when the clip bin shaft (21) is pulled back to the initial position of the proximal end of the clip bin shaft, the connection of the driving shaft (11) with the clip bin shaft (21) becomes a separable connection under the axial external force. The clip applier has a stable and reliable pulling back effect, avoiding the problem of being unable to trigger again caused by inability of the clip bin shaft to be reset. Also disclosed is a method for driving a clip bin shaft of a clip applier.
