Dependent Claim
29 words
The endoscopic system according to claim 5 , wherein said fixing member is formed of an elastic member detachably mounted to the distal end portion by an elastic deformation.
Claim 9
Dependent Claim
22 words
The endoscopic system according to claim 6 , wherein said elastic member is made from a group consisting of silicon, elastic elastomer.
Claim 10
Dependent Claim
25 words
The endoscopic system according to claim 5 , wherein said fixing member is formed of an adherence member for adhering to the distal end portion.
Claim 11
Independent Claim
187 words
A method for positioning an indwelling tube comprising: detachably mounting a guide catheter fixing member to a distal end portion of an elongate insertion part to be inserted into the body cavity; fixing and holding a distal end portion of a guide catheter along the axial direction of said insertion part to said guide catheter fixing member; inserting said insertion part into a body cavity to a targeted position, while the distal end portion of said guide catheter is fixedly held; withdrawing the distal end portion of said guide catheter from said guide catheter fixing member; inserting a guide wire into said guide catheter to permit the end of said guide wire to protrude from the distal end of said guide catheter; permitting the end of said guide wire to reach said targeted position, while said guide catheter is pulled out of the body cavity; inserting said indwelling tube along said guide wire from the outside of the body cavity to said targeted position to position said indwelling tube at said targeted position inside the body cavity; and withdrawing said insertion part out of the body cavity.
Claim 12
Independent Claim
187 words
A method for positioning an indwelling tube comprising: detachably mounting a guide catheter fixing member to a distal end portion of an elongate insertion part to be inserted into the body cavity; fixing and holding a distal end portion of a guide catheter along the axial direction of said insertion part to said guide catheter fixing member; inserting said insertion part into a body cavity to a targeted position, while the distal end portion of said guide catheter is fixedly held; withdrawing the distal end portion of said guide catheter from said guide catheter fixing member; inserting a guide wire into said guide catheter to permit the end of said guide wire to protrude from the distal end of said guide catheter; permitting the end of said guide wire to reach said targeted position, while said guide catheter is pulled out of the body cavity; inserting said indwelling tube along said guide wire from the outside of the body cavity to said targeted position to position said indwelling tube at said targeted position inside the body cavity; and withdrawing said insertion part out of the body cavity.
