Abstract

A manipulating handle for a successive clipping device comprises: a cylindrical handle main body connected to a sheath with a manipulating wire extending from the sheath being arranged in an interior thereof; a slider engaged with the manipulating wire for moving the manipulating wire in the axial direction of the handle main body; and a slider-movement-amount regulating member attached onto the outer circumferential surface of the handle main body so as to be rotatable in a circumferential direction of the handle main body, for regulating, according to a rotational position in a circumferential direction thereof, an amount of movement of the slider in the axial direction of the handle main body to one of a plurality of different amounts of movement required for respective clipping manipulations using a plurality of clips connected to the manipulating wire.

Claims

1. A manipulating handle for a successive clipping device, the manipulating handle comprising:

a sheath;

a manipulating wire, which is arranged in an interior of the sheath, and has a forward end to which a plurality of clips are connected;

a cylindrical handle main body connected to the sheath, with the manipulating wire extending from the sheath being arranged in an interior thereof;

a slider, which is attached onto an outer circumferential surface of the handle main body to be movable in an axial direction thereof, and engaged with the manipulating wire, for moving the manipulating wire in the axial direction of the handle main body; and

a slider-movement-amount regulating member attached onto the outer circumferential surface of the handle main body so as to be rotatable in a circumferential direction of the handle main body, for regulating, according to a rotational position in a circumferential direction thereof, an amount of movement of the slider in the axial direction of the handle main body to one of a plurality of different amounts of movement required for respective clipping manipulations using the plurality of clips connected to the manipulating wire,

wherein the slider is moved in the axial direction of the handle main body so as to move the manipulating wire arranged in the interior of the sheath in an extending direction of the sheath, to thereby move the plurality of clips connected to the manipulating wire.

2. The manipulating handle for the successive clipping device according to claim 1, wherein:

the slider-movement-amount regulating member has a plurality of regulating portions, which correspond to the plurality of different amounts of movement, and are arranged at respective different axial positions according to circumferential positions thereof; and

the slider has an engagement member which is engaged with one of the plurality of regulating portions selected according to the rotational position of the slider-movement-amount regulating member.

3. The manipulating handle for the successive clipping device according to claim 2, wherein:

the handle main body has a guide groove of a predetermined length formed along the axial direction thereof; and

the slider is movable in the axial direction in a state in which the engagement member is guided by the guide groove of the handle main body.

4. The manipulating handle for the successive clipping device according to claim 1, further comprising a position regulating member, which is fixed to the handle main body and fit-engaged with the slider-movement-amount regulating member, for regulating a position of the slider-movement-amount regulating member in at least one of a rotating direction thereof and an axial direction thereof.

5. The manipulating handle for the successive clipping device according to claim 4, wherein the position regulating member and the slider-movement-amount regulating member have, in respective contact surfaces thereof, a plurality of indented projections and recesses each formed along respective circumferential directions thereof, and the plurality of indented projections and recesses of one of the contact surfaces and the plurality of indented projections and recesses of another contact surface are caused to mesh with each other so that the position of the slider-movement-amount regulating member is regulated.

6. The manipulating handle for the successive clipping device according to claim 5, further comprising:

a biasing means for biasing the contact surface of the slider-movement-amount regulating member toward the contact surface of the position regulating member.

7. The manipulating handle for the successive clipping device according to claim 5, wherein the plurality of respective projections and recesses of the position regulating member and the slider-movement-amount regulating member have shapes of saw teeth to allow the slider-movement-amount regulating member to be rotatable only in a single predetermined direction.

8. The manipulating handle for the successive clipping device according to claim 1, wherein at least a part of the slider-movement-amount regulating member is replaceable so as to differentiate, according to a type of each of the clips to be used, the amount of movement of the slider to be regulated.

9. The manipulating handle for the successive clipping device according to claim 8, further comprising:

a single cylindrical slider guide base portion fit-engaged with the handle main body; and

a plurality of replaceable cylindrical slider guide attachment/detachment portions corresponding to a plurality of types of the clips,

each of the slider guide attachment/detachment portions being detachably attached to the slider guide base portion and having a plurality of regulating portions correspond to the plurality of different amounts of movement and arranged at different axial positions according to circumferential positions thereof;

one of the plurality of slider guide detachment/attachment portions, which is selected according to the type of each of the clips to be used, and the slider guide base portion forming the slider-movement-amount regulating member.

10. The manipulating handle for the successive clipping device according to claim 9, wherein the slider has an engagement member to be engaged with one of the plurality of regulating portions which is selected according to a rotational position of the slider guide attachment/detachment portion used in the slider-movement-amount regulating member.

11. The manipulating handle for the successive clipping device according to claim 9, wherein each of the slider guide attachment/detachment portions includes a pair of substantially semicircular tubular members, the pair of substantially semicircular tubular members are combined with the handle main body interposed therebetween to provide a cylindrical shape, and a forward end portion thereof is fitted into the slider guide base portion so that the slider guide attachment/detachment portion is attached to the handle main body.

12. The manipulating handle for the successive clipping device according to claim 9, wherein the plurality of slider guide attachment/detachment portions have respective marked portions which allow visual recognition of the types of the clips corresponding thereto.

13. The manipulating handle for the successive clipping device according to claim 12, further comprising a plurality of clip cases corresponding to the plurality of types of the clips for accommodating therein the corresponding clips,

the marked portion of the slider guide attachment/detachment portion and the clip case which correspond to the same type of clip being colored in the same color.

14. A successive clipping device comprising:

the manipulating handle for the successive clipping device according to claim 1;

a plurality of clips loaded in an interior of a forward end of the sheath each in a state of being engaged with another of the clips arranged in a front-rear direction; and

a connecting member connected to the rearmost one of the plurality of clips,

wherein a forward end of the manipulating wire is detachably connected to the connecting member in the sheath.
