Abstract

An endoscope including; a fixing member detachably mounted to a distal end portion of an endoscope insertion part for detachably fixing and holding a distal end portion of an indwelling tube or a distal end portion of a guide member for guiding the indwelling tube, both of which are provided along the axial direction of the insertion part, to the distal end portion of the insertion part.

Claims

1. An endoscopic system comprising:

an endoscope including an elongate insertion part for insertion into a body cavity;

a guide member for guiding an indwelling tube into the body cavity; and

a fixing member mounted to a distal end portion of the elongated insertion part, at least a distal-most end portion of the guide member being detachably fixed to and held by the fixing member along an axial direction of the endoscope in such a way that the distal-most end portion of the guide member is accommodated within the fixing member.

2. The endoscopic system according to claim 1, wherein said fixing member is formed of an elastic member detachably mounted to the distal end portion by an elastic deformation.

3. The endoscopic system according to claim 2, wherein said elastic member is made from a group consisting of silicon or elastic elastomer.

4. The endoscopic system according to claim 1, wherein said fixing member is formed of an adherence member for adhering to the distal end portion.

5. An endoscopic system comprising:

an endoscope including an elongated insertion part for insertion into a body cavity;

an indwelling tube; and

a fixing member mounted to a distal end portion of the elongated insertion part, at least a distal-most end portion of the indwelling tube being detachably fixed to and held by the fixing member along an axial direction of the endoscope in such a way that the distal-most end portion of the indwelling tube is accommodated within the fixing member.

6. 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.

7. The endoscopic system according to claim 6, wherein said elastic member is made from a group consisting of silicon, elastic elastomer.

8. The endoscopic system according to claim 5, wherein said fixing member is formed of an adherence member for adhering to the distal end portion.

9. 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.

10. An endoscopic system comprising:

an endoscope including an elongate insertion part for insertion into a body cavity;

a guide member for guiding an indwelling tube into the body cavity; and

a fixing member detachably mounted to a distal end portion of the endoscope insertion part, at least a distal-most end portion of the guide member being detachably fixed to and held by the fixing member, said fixing member having a holding portion for accommodating at least said distal-most end portion of said guide member.

11. An endoscopic system comprising:

an endoscope including an elongate insertion part for insertion into a body cavity;

an indwelling tube; and

a fixing member detachably mounted to a distal end portion of the elongated insertion part, at least a distal-most end portion of the indwelling tube being detachably fixed to and held by the fixing member, said fixing member having a holding portion for accommodating at least said distal-most end portion of the indwelling tube.

12. An endoscopic system comprising:

an endoscope including an elongate insertion part for insertion into a body cavity;

a guide member for guiding an indwelling tube into the body cavity; and

a fixing member mounted to a distal end portion of the elongated insertion part, at least a distal end portion of the guide member being detachably fixed to and held by the fixing member along an axial direction of the elongated insertion part so that the guide member is to be released from the fixing member by pulling toward a proximal side of the endoscope during insertion.

13. An endoscopic system comprising:

an endoscope including an elongated insertion part for insertion into a body cavity;

an indwelling tube; and

a fixing member mounted to a distal end portion of the elongated insertion part, at least a distal end of the indwelling tube being detachably fixed to and held by the fixing member along an axial direction of said elongated insertion part so that the indwelling tube is to be released from the fixing member by pulling toward a proximal side of the endoscope during insertion.
