Abstract

An insertion auxiliary implement of the present invention includes: a tubular part into which a flexible endoscope insertion part which is insertable into a body cavity, and one of a treatment tool and a channel into which the treatment tool is insertable, are insertable; and a sealing member which has through holes for supporting the endoscope insertion part and one of the treatment tool and the channel in the tubular part, and which airtightly and movably contacts each of a periphery of the endoscope insertion part, a periphery of the treatment tool or a periphery of the channel, and an inner surface of the tubular part, and thereby maintains airtightness between a distal end and a proximal end inside the tubular part.

the first slide portion is a convexity which contacts the inner surface of the tubular part;

the second slide portion is a convexity which contacts the periphery of the endoscope insertion part; and

the third slide portion is a convexity which contacts the periphery of the treatment tool or the periphery of the channel.

4. The insertion auxiliary implement, according to claim 3, wherein

in the case in which the first slide portion is a convexity which contacts the inner surface of the tubular part, the convexity has elasticity and external dimensions larger than internal dimensions of the tubular part.

5. The insertion auxiliary implement, according to claim 3, wherein

in the case in which the second slide portion is a convexity which contacts the periphery of the endoscope insertion part, the convexity has elasticity and internal dimensions smaller than external dimensions of the periphery of the endoscope insertion part.

6. The insertion auxiliary implement, according to claim 3, wherein

in the case in which the third slide portion is a convexity which contacts the periphery of the treatment tool or the periphery of the channel, the convexity has elasticity and internal dimensions smaller than external dimensions of the periphery of the treatment tool or the periphery of the channel.

7. The insertion auxiliary implement, according to claim 1, further comprising a reinforcing band which wraps around the sealing member so that an outer portion of the sealing member, which is away from the inner surface of the tubular part, is covered.

8. The insertion auxiliary implement, according to claim 7, wherein

the reinforcing band is non-contacting with the inner surface of the tubular part when the sealing member is inserted in the tubular part.

9. The insertion auxiliary implement, according to claim 1, further comprising a fastener which fastens the endoscope insertion part, and one of the treatment tool and the channel together.

10. The insertion auxiliary implement, according to claim 1, wherein

the channel in which the treatment tool is inserted is inserted in the through hole of the sealing member, and a sealing structure is provided between the inner surface of the channel and the periphery of the treatment tool.

11. The insertion auxiliary implement, according to claim 1, wherein

the sealing member comprises a first slide portion which airtightly and slidably contacts the inner surface of the tubular part, at at least two locations along the axial direction of the tubular part.

12. The insertion auxiliary implement, according to claim 1, wherein

the sealing member comprises a second slide portion which airtightly and slidably contacts the periphery of the endoscope insertion part, at at least two locations along the axial direction of the tubular part.

13. The insertion auxiliary implement, according to claim 1, wherein

the sealing member comprises a third slide portion which airtightly and slidably contacts the periphery of the treatment tool or the periphery of the channel, at at least two locations along the axial direction of the tubular part.
