Abstract
Abstract A guiding device for treatment accessories of an endoscope includes a guiding tube and a fixing device. The guiding tube is long enough to extend from a forceps channel of the endoscope and is provided with a bent portion at a distal end thereof. The fixing device positions the guiding tube to having a predetermined positional relationship with respect to the entrance of the forceps channel such that the bent portion bends in a predetermined direction with respect to the exit of the forceps channel.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
159 words
A guiding device in combination with an endoscope, comprising a guiding tube inserted through a forceps channel of said endoscope to guide a treatment accessory which is inserted in said guiding tube, said guiding tube having a distal end and a proximal end, a distal portion of said guiding tube at said distal end extending by a predetermined amount from an exit of said forceps channel, said distal portion of said guiding tube being provided with a bent portion, said guiding tube being further provided with a directive bending portion, said guiding tube being formed to have a tendency to bend easily in one direction, said directive bending portion corresponding to, when said distal portion of said guiding tube is extended from said forceps channel, a bendable portion of said forceps channel, such that a direction in which said bent portion is bent and said direction in which said directive bending portion tends to bend have a predetermined relationship.
Claim 2
Dependent Claim
159 words
A guiding device in combination with an endoscope, comprising a guiding tube inserted through a forceps channel of said endoscope to guide a treatment accessory which is inserted in said guiding tube, said guiding tube having a distal end and a proximal end, a distal portion of said guiding tube at said distal end extending by a predetermined amount from an exit of said forceps channel, said distal portion of said guiding tube being provided with a bent portion, said guiding tube being further provided with a directive bending portion, said guiding tube being formed to have a tendency to bend easily in one direction, said directive bending portion corresponding to, when said distal portion of said guiding tube is extended from said forceps channel, a bendable portion of said forceps channel, such that a direction in which said bent portion is bent and said direction in which said directive bending portion tends to bend have a predetermined relationship.
Claim 3
Dependent Claim
89 words
The guiding device in combination with an enclosure according to claim 1, further comprising a fixing device being provided to said guiding tube at said proximal end, said fixing device detachably mounted to an entrance of said forceps channel such that said guiding tube may be oriented at any rotational direction with respect to an axis of said forceps channel at said entrance, wherein said distal portion of said guiding tube extends from said forceps channel by said predetermined amount when said fixing device is mounted to said entrance.
Claim 4
Dependent Claim
47 words
The guiding device in combination with an enclosure according to claim 1, further comprising a fixing device detachably mounted to an entrance of said forceps channel such that said guiding tube is inserted through said fixing device and is slidably and frictionally supported by said fixing device.
Claim 5
Dependent Claim
38 words
The guiding device in combination with an enclosure according to claim 1, wherein said direction in which said bent portion is bent and said direction in which said directive bending portion tends to bend are the same direction.
Claim 6
Dependent Claim
37 words
The guiding device in combination with an enclosure according to claim 1, wherein said direction in which said bent portion is bent and said direction in which said directive bending portion tends to bend are opposite directions.
Claim 7
Dependent Claim
150 words
A guiding device in combination with an endoscope, comprising a guiding tube inserted through a forceps channel of said endoscope to guide a treatment accessory which is inserted in said guiding tube, said guiding tube having a distal end and a proximal end, a distal portion of said guiding tube at said distal end extending by a predetermined amount from an exit of said forceps channel, said distal portion of said guiding tube being provided with a bent portion, wherein said guiding tube is further provided with a curved portion, said curved portion being formed to curve in one direction, said curved portion corresponding to, when said distal portion of said guiding tube is extended from said forceps channel, a bendable portion of said forceps channel, such that a direction in which said bent portion is bent and said direction in which said curved portion curves have a predetermined relationship.
Claim 8
Dependent Claim
150 words
A guiding device in combination with an endoscope, comprising a guiding tube inserted through a forceps channel of said endoscope to guide a treatment accessory which is inserted in said guiding tube, said guiding tube having a distal end and a proximal end, a distal portion of said guiding tube at said distal end extending by a predetermined amount from an exit of said forceps channel, said distal portion of said guiding tube being provided with a bent portion, wherein said guiding tube is further provided with a curved portion, said curved portion being formed to curve in one direction, said curved portion corresponding to, when said distal portion of said guiding tube is extended from said forceps channel, a bendable portion of said forceps channel, such that a direction in which said bent portion is bent and said direction in which said curved portion curves have a predetermined relationship.
Claim 9
Dependent Claim
35 words
The guiding device in combination with an enclosure according to claim 6, wherein said direction in which said bent portion is bent and said direction in which said curved portion curves are the same direction.
Claim 10
Dependent Claim
34 words
The guiding device in combination with an enclosure according to claim 6, wherein said direction in which said bent portion is bent and said direction in which said curved portion curves are opposite directions.
Claim 11
Dependent Claim
89 words
The guiding device in combination with an endoscope according to claim 6 further comprising a fixing device provided to said guiding tube at said proximal end, said fixing device being detachably mounted to an entrance of said forceps channel such that said guiding tube may be oriented at any rotational direction with respect to an axis of said forceps channel at said entrance, wherein said distal portion of said guiding tube extends from said forceps channel by said predetermined amount when said fixing device is mounted to said entrance.
Claim 12
Dependent Claim
46 words
The guiding device in combination with an endoscope according to claim 6, further comprising a fixing device mounted to an entrance of said forceps channel such that said guiding tube is inserted through said fixing device and is slidably and frictionally supported by said fixing device.
