The one end of more traction ropes (4) is passed down through release head (3) inside at the top of release head (3) and is arranged in gastroscope/intestines Mirror/looping and binding device end；

Downlink is distinguished along release head (3) lateral surface from the top of release head (3) in the other end of more traction ropes (4), and respectively Knot (5) are set below corresponding reducing marmem closure folder.

14. the multiple variable diameter marmem of stack according to claim 13 is closed clamp device, it is characterised in that:

A rope groove (6) axially arranged is arranged in the lateral surface of release head (3)；

Top rope groove (6) downlink of the other end of traction rope (4) from release head (3)；

The quantity of reducing marmem closure folder is 3 to 6.
