1. A clipping device comprising:
- a clip having a pair of arm portions diverging elastically; and
a tubular clamping member fitted onto the pair of arm portions of the clip, for releasing the clip when being situated on a proximal end side of the pair of arm portions so as to cause the pair of arm portions to diverge, and for clamping the clip when being situated on a forward end side of the pair of arm portions so as to cause the pair of arm portions to close,each of the pair of arm portions including a projection portion which is formed in a vicinity of a forward end portion thereof to have a width inhibiting passage of the clamping member, and an engagement portion which is formed in a region adjacent to a proximal end side of the projection portion to be engaged with the clamping member,the clamping member being engaged with the engagement portion of each of the pair of arm portions to maintain clamping of the clip so that the pair of arm portions holds an object to be treated.

9. A clipping device comprising:
-
a sheath having a proximal end portion and a forward end portion; a plurality of clips which are loaded into the forward end portion of the sheath while being engaged with other clips connected together in front and back directions, and each of which comprises a pair of arm portions diverging elastically; a plurality of tubular clamping members corresponding to the plurality of clips and fitted into the sheath so as to be capable of advancing and retreating, each being fitted onto the pair of arm portions of the corresponding clip, each releasing the corresponding clip when being situated on a proximal end side of the pair of arm portions so as to cause the pair of arm portions to diverge, and each clamping the corresponding clip when being situated on a forward end side of the pair of arm portions so as to cause the pair of arm portions to close; a plurality of retaining members corresponding to the plurality of clamping members and connected to the corresponding clamping members, and each covering an engagement portion of the clip, onto which the corresponding clamping member is fitted, so as to maintain the plurality of clips in a connected state; and a manipulating wire connected to a rearmost one of the plurality of clips, for pulling a clip string constituted by the plurality of clips, each of the pair of arm portions of each clip including a projection portion which is formed in a vicinity of a forward end portion thereof to have a width inhibiting passage of the clamping member, and an engagement portion which is formed in a region adjacent to a proximal end side of the projection portion to be engaged with the clamping member, each of the clamping members being engaged with the engagement portion of each of the pair of arm portions of the corresponding clip to maintain clamping of the clip. - View Dependent Claims (10)
