First, an endoscope is provided with a channel for introducing a treatment tool such as forceps into a body cavity.
This channel opens to the outside at the open end on the hand operation section side. Therefore, there is a problem that air, dirt, etc. in the living body cavity leaks from this open end, so the open end is closed with a plug.

By the way, the above-mentioned closure plug is made of an elastic material such as rubber, and is provided with a slit for inserting a treatment tool therethrough. This slit is normally closed airtight and is opened by pressing the treatment instrument against it. However, since the conventional closure plug is simply formed into a cap shape and fitted into the open end of the above-mentioned open end,
For example, when the pressure inside the body cavity increases, the slit opens and air leaks, or when the suction operation is stopped, the dirt that was sucked into the channel flows into the open end, and due to the pressure, the slit opens and air leaks. This caused problems such as the slits opening and filth flowing out.

On the other hand, the other end of the main passage 25 provided with the collar 29 is arranged close to one side of the lower part of the grip cover 9. A treatment instrument insertion opening 34 is provided in a portion of the grip cover 9 adjacent to the collar 29.
is configured. The treatment instrument insertion opening portion 34 is formed by providing an attachment hole 35 in the grip cover 9, and an insertion opening body 36 is inserted into the attachment hole 35 through a ring packing 37 in an airtight manner. The insertion port body 36
is formed into a cylindrical shape as a whole, and is provided with a bayonet receiver 38 at its inner end that engages with the bayonet pawl 30 to restrict axial movement of the insertion port body 36. Further, the inner diameter of the inner end portion of the insertion port body 36 is formed to be relatively larger than that of other portions. A tubular damper member 39 that is elastically deformable in the axial direction is fitted into this large diameter inner cavity 39a. When the insertion port body 36 is connected to the branch pipe body 23, the damper member 39 is compressed in the axial direction. A seal portion 39b is formed at the end of the damper member 39, which is compressed by the outer circumferential surface of the branch pipe body 23 and the inner circumferential surface of the insertion port body 36 to maintain airtightness between them. Furthermore, a flange portion 40 is formed at the outer end of the insertion port body 36 . This flange portion 40 is the large diameter portion 4
1, and a small diameter part 42 formed on the outer end side of the large diameter part 41, and a screw 43 is provided on the outer peripheral surface of this small diameter part 42. Further, a first mounting groove 44 that is open to the outer end surface and outer peripheral surface of the large diameter portion 41 is formed along the axial direction. On the other hand, a second mounting groove 45 is formed in the inner peripheral surface of the mounting hole 35 along the axial direction, and one end thereof is open to the outer end surface of the insertion port 34 . This second
The mounting groove 45 faces the first mounting groove 44 when the insertion port body 36 is connected to the branch pipe body 23. A stopper member 46 having a width spanning both of the mounting grooves 44 and 45 facing each other is inserted into the first and second mounting grooves 44 and 45 facing each other.
6 restricts movement of the insertion port body 36 in the circumferential direction. A tongue piece 48 in which a locking hole 47 is bored is protruded from the end surface of the stopper member 46, and the stopper member 46 can be removed by engaging a tool (not shown) with the locking hole 47. I'm starting to be able to do it. Further, a retainer ring 49 is screwed onto the small diameter portion 42 of the collar portion 40, thereby preventing the stopper member 46 from falling off. In addition,
A locking groove 50 is formed in the end face of the presser ring 49, and the presser ring 49 can be attached and removed through the locking groove 50 using a tool (not shown).

On the other hand, a cylindrical portion 51 having a smaller diameter than the small diameter portion 42 of the flange portion 40 is formed at the outer end of the insertion port body 36, and the end of the cylindrical portion 51 has a manual operation portion for a channel for inserting a treatment instrument. Mounting part 52 as side opening end
is provided. The mounting portion 52 includes a protrusion 53 having a larger diameter than the cylindrical portion 51, and the insertion port body 36.
It has a pressing surface 54 that slopes low toward the inside in the radial direction. A plug 55 made of an elastic material such as rubber is attached to the attachment portion 52. That is, the plug 55 has a cap shape with an open lower end surface, and the inner surface of its peripheral wall 55a has a contact portion 56 that presses against the outer peripheral surface of the cylindrical portion 51, and an inner peripheral groove that fits into the protrusion 53. 57 are formed. Further, a truncated conical protrusion 58 is provided on the inner surface of the end wall 55b of the plug 55, and an outer peripheral tapered surface 59 of the protrusion 58 is in pressure contact with the pressing surface 54. Furthermore, the end wall 55b of the occlusion plug 55 has a + or - shape into which a treatment instrument (not shown) can be inserted into the center.
A shaped slit 60 is formed, and an arcuate concave surface 61 is formed on the outer surface so that the treatment tool can be easily inserted into the slit 60. That is, as shown in FIG. 3, the blocker 55 is formed such that the inner diameter d 1 of the abutting portion 56 is smaller than the outer diameter d 2 of the cylindrical portion 51 of the insertion port body 36 , and the outer periphery of the protrusion 58 is tapered. The inclination angle θ 1 of the surface 59 with respect to the horizontal line L is larger than the inclination angle θ 2 of the pressing surface 54 . Therefore, the circumferential wall of the plug 55 attached to the insertion port body 36 is elastically deformed radially outward, and the protrusion 58
is compressed radially inward.

When the closure plug 55 having such a configuration is used, the peripheral wall 55a is elastically deformed radially outward, and a force in the direction indicated by the arrow A is generated on the end wall 55b as shown in FIG. Also, as the protrusion 58 is compressed radially inward, a force in the direction indicated by arrow B is generated on the end wall 55b. Therefore, the forces in the directions indicated by arrows A and B act in the direction of closing the slit 60 formed in the end wall 55b, which may cause pressure to increase in the body cavity or dirt to enter the insertion port body 36. Even if it flows in, there is almost no leakage in the slit 60.

Further, since the end wall 55b of the occluding plug 55 is curved inward as a whole into the insertion port body 36, the slit 60 opens when a treatment instrument (not shown) is pressed against the concave surface 61. Because it is easy to use, it is easy to insert the treatment tool. Furthermore, when the pushing force of the treatment instrument is weakened, the forces in the directions of arrows A and B acting on the end wall 55b as described above act in the direction of closing the slit 60, so that the treatment instrument and the inner surface of the slit 60 are in close contact with each other. , the airtightness of that part is maintained relatively well. In this embodiment, the treatment instrument insertion channel is constituted by the tube 22, the main passage 25, and the internal passage of the insertion port body 36.

As described above, the present invention provides a closure plug for an endoscope that is made of an elastic material and has a slit through which the treatment instrument is passed, which closes the opening end on the hand operation section side of the channel for guiding the insertion of the treatment instrument. The inner diameter of the inner surface of the peripheral wall that abuts the outer peripheral surface of the open end of the plug is smaller than the outer diameter of the outer peripheral surface of the open end, and the inner surface of the end wall of the plug is formed into a truncated conical protrusion. Since the tapered surface of the outer periphery of the plug is pressed against the inner surface of the opening end, when the plug is attached to the opening end, the peripheral wall is elastically deformed radially outward, and the end wall of the plug closes the slit. A directional force acts. This effect increases the airtightness of the slit, which has the advantage of making it difficult for air and dirt in the body cavity to leak through the slit.
