In this case, the gap between the curved surfaces 214a and 224a of the pair of clips facing each other is narrowed, while the opening angles of the first intersecting plates 213 and 223 intersected in the X-shape with the inclined plates 212 and 222 are larger than the initial state. It can be wide open.

Then, inclined plates 212 and 222 having the tong pieces spread outward to the human tissue, and as shown in Figure 7d, when the wire 120 is reversed again (in the right side in the drawing) in the insertion tube, the clip As the first intersecting plates 213 and 223 enter the inner hole of the holder 230, the inclined plates 212 and 222 are closed so as to contact the tong pieces 211 and 221, and the biological tissue is formed by the pair of tongs of the clip tip. It can be easily taken out by clamping.

Finally, as shown in FIGS. 7E and 7D, the operation of separating the clip part 200 from the insertion pipe together with the connection port of the wire is performed when the wire in the insertion pipe is reversed again (right side in the drawing). The elastic piece is in contact with the end of the insertion tube by separating and detaching the connector 125 from the grooves 216a and 226a of the bending plate formed up and down to form a coupler correspondingly coupled to the connector 125 of the wire 120. Along with the clip holder will be separated and separated a pair of clips (210, 220).

Then, the plane 236 formed in the inner hole of the clip holder 230, as shown in Figure 8, in the bundle 126 on the rectangular cross section extending from the connector 125 when the connection between the connector and the clip. By contacting the formed contact surface (126a), the clip disposed in the insertion tube during the rotation operation of the wire is to be able to rotate with the wire in the insertion tube together with the clip holder.

On the other hand, the guide cover is inserted in the rear end of the clip holder 230 at the inlet of the guide path 320 is provided in the split cover (301, 302) of the cartridge 300 is inserted into the end of the insertion tube 110 ) May be provided with a latching elastic piece 345 which protrudes toward the guide path 320 to prevent separation from the outside, so that the free end is in contact with the rear end of the guide moving ring 240 to generate a locking force.

Accordingly, the locking elastic piece 345 allows the insertion through the inlet of the guideway while allowing the clip holder and the guide ring to enter through the inlet of the guideway while being elastically opened. It is to prevent the departure of the guide movement ring.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
