くきわめて不衛生であつた。 In general, an endoscope has an insertion channel formed from its operating section to the distal end of its insertion section, through which various treatment tools for performing biopsy or hemostasis are inserted. Further, in order to perform suction through the insertion channel, a suction pipe line leading to a suction pump is connected to the middle of the insertion channel via a switching valve. Then, dirt in the body cavity enters the insertion channel due to insertion and withdrawal of the treatment instrument or suction operation, and
There is a danger that the filth will be scattered outside from the entrance. For this reason, a slotted rubber stopper or the like is usually provided at the entrance to keep it closed and to wrap around the treatment instrument when it is inserted. however,
When the treatment tool is pulled out, a gap is inevitably created between the treatment tool and the rubber stopper, and dirt adhering to the treatment tool scatters from the gap and easily adheres to the surgeon's fingers and face, making it extremely unsanitary.
本考案は上記事情に着目してなされたもので、

支持されている。 Reference numeral 1 in FIG. 1 is an endoscope in which an insertion section 3 is connected to an operating section 2. As shown in FIG. The main body 4 of the operating section 2 has a grip section 5.
An eyepiece 6 is provided on the end surface of the main body 4 on the hand side. An angle knob 8, an air/water supply switching valve 9, and a suction switching valve 10 are provided on the side surface of the proximal end 7, and a cable 11 is connected thereto. Furthermore, the main body 4 of the operating section 2 is provided with an inlet 13 for an insertion channel 12 located on the insertion section 3 side. As shown in FIG. 2, the insertion channel 12 is inserted from the operating section 2 to the insertion section 3, and the distal end of the insertion channel 12 is open at the distal end portion 14 of the insertion section 3. Further, in the operation section 2, a suction pipe line 15 leading to a suction pump (not shown) is connected to the middle of the insertion channel.
This suction conduit 15 is led to a connector (not shown) through its operating portion 2 and cable 11, so that it can be connected to the suction pump. Note that the suction switching valve 10 is inserted in the middle of the suction conduit 15. Further, at the entrance 13 of the insertion channel 12, a blocking plug 18 formed by forming a slot 17 in the elastic member 16 is provided, and this blocking plug 18 is supported by a retaining ring 19.

衛生的に使用することができる。 When performing a biopsy or hemostasis, the treatment instrument 21 is inserted into the insertion channel 12 from the inlet 13, and after cell collection or hemostasis, the treatment instrument 21 is pulled out in the direction of the arrow as shown in FIG. Dirt, mucus, etc. attached to the circumferential surface of the treatment instrument 21 pass through the gap between the plug 18 and the inlet 1.
3 may scatter to the outside, but it is blocked by the partition member 20 and does not reach the hand of the operator who grips the grip portion 5, thereby preventing staining. That is, the endoscope 1 can be used hygienically because the vicinity of the grip portion 5 and the proximal end portion 7 are protected from flying dirt, mucus, and the like.
