Abstract
In a forceps 1 of the present invention, an operating section 12 is provided with a main body 12 and a pair of slider sections 13 which advance and retract an operating wire 11 by relative closing-and-departing motions thereof; the slider section 13 is provided with a thumb hole section 16 to which a thumb is engaged to operate the operating section 12; the main body 12 is provided with a second finger-receiving section 21 having a sandwiched section 21a to be sandwiched between a first finger and a second finger and thereby being engaged with the first finger and the second finger; and when an operating duct section 6 is inserted within a forceps channel, a distance from the second finger-receiving section 21 to a forceps opening is longer than a distance from a thumb hole section 16 to the forceps opening.
Claims21
A treatment tool for an endoscope comprising:
- an operating duct section which is to be inserted into a forceps channel of the endoscope;
- a treatment tool distal section which is provided on a distal end side of this operating duct section;
- and an operating section which is provided on a bottom end side of the operating duct section, wherein:
- the operating duct section includes an operating wire of which one end is joined to the treatment tool distal end;
- and
- the operating section includes a pair of driving-operation sections which advance and retract the operating wire by relative closing-and-departing motions thereof;
- and wherein:
- one of the pair of driving-operation sections is provided with a first finger-receiving section to which a finger which operates the operating section is engaged, while the other is provided with a second finger-receiving section which has a sandwiched section to be sandwiched between the other fingers, and onto which the other fingers are to be engaged;
- and an arrangement thereof is made such that, when the operating duct section is inserted within the forceps channel, a distance from the second finger-receiving section to an opening of the forceps channel, on the operating section side of the endoscope, becomes longer than a distance from the first finger-receiving section to the opening of the forceps channel, on the operating section side of the endoscope.
A treatment tool for an endoscope comprising:
- an operating duct section which is to be inserted into a forceps channel through a forceps opening of the endoscope;
- a treatment tool distal section which is joined to a distal end side of this operating duct section;
- and an operating section which is joined to a bottom end side of the operating duct section and operates the treatment tool distal section, wherein:
- the operating duct section includes an operating wire which drives the treatment tool distal section;
- the operating section includes:
- a body of which one end is joined to a bottom end of the operating duct section, and stands on the forceps opening while the operating duct section is inserted within the forceps channel;
- and a slider section which is joined to a bottom end of the operating wire, and is advanceable and retractable between one end and another end of the body;
- and
- the slider section is provided with one first finger-receiving section, while another end of the body is provided with a second finger-receiving section.
Comprising:
- a flexible operating duct section which is to be inserted into a forceps channel through a forceps opening of an endoscope;
- a treatment tool distal section which is joined to a distal end side of this operating duct section;
- and an operating section which is joined to a bottom end side of the operating duct section and operates the treatment tool distal section, wherein:
- the operating duct section includes an operating wire which drives the treatment tool distal section;
- and
- the operating section includes:
- a first driving-operation section which is supported beside the operating duct section;
- a second driving-operation section which is provided on a side of the treatment tool distal end section than the first driving-operation section, and advances and retracts with respect to the first driving-operation section;
- and
- a turning member which joins between the second driving-operation section and a bottom end of the operating wire, and has hardness and a substantial U-shape.
