態を解き、クリツプ１を留置するものである。 Therefore, Japanese Utility Model Application No. 62-170010 discloses a clipping device that solves the above-mentioned problems. As shown in FIGS. 10 and 11, this clip device has a hook 2 provided at the base end of a clip 1, and this hook 2 is engaged with a connecting plate 3 that engages with a hook provided at the tip of an operating wire. This is then inserted into the presser tube 4, and the presser tube 4 is filled with a filler to make the clip 1 into a cassette type. This results in
When placing the clip 1, move the connecting plate 3 toward the proximal side via the operating wire, and press the hook 2 of the clip 1.
The clip 1 is released from the engagement between the clip 1 and the connecting plate 4, and the clip 1 is left in place.
しかしながら、クリツプ１は、鉤２が引き伸ば
