Furthermore, a communication hole 21 is formed on the inner surface of the lower part of the injection hole 12, and communicates with the lower part of a ventilation hole 20, which will be described later.The communication hole 21 is normally open, but when the slider 15 is pushed in, It is closed by the slider 15.

That is, the communication hole 21 is opened and closed by the slider 15.

On the other hand, the ventilation hole 20 is integrally formed in the side wall portion of the adapter body 7, and the injection hole 14 of the injection hole 12 is formed integrally with the side wall of the adapter body 7.
A vent hole 22 opening to the outside is provided alongside.

The communication hole 21 is formed to pass through the side wall of the adapter body 7, and is connected to the injection hole 12 and the ventilation hole 2.
The bottom comrades of 0 are directly connected to each other.

Furthermore, a rubber cap 23 is fitted onto the outer end of the adapter body 7, and the cap 23 has two openings 24 and 25 formed therein corresponding to the injection port 14 and the ventilation port 22. It has been.

That is, the inlet 14 and the vent 22 have their openings 24 . It opens to the outside through 25.

Then, as shown in FIG. 3, the opening 24. 25 can be closed at the same time with the same finger 26.

On the other hand, the second adapter section 5 is connected to the first adapter section 4.
Although it has a structure partially similar to that of the endoscope, the adapter body 28, which is approximately cylindrical, is removably fitted into the adapter receiver 27, which is fixed and attached to the operating section body 1 of the endoscope. Connected to the inner end 29 of the body 28 is a tube 31 forming a second channel 30 of the endoscope.

Further, the adapter main body 28 is adapted to be locked and fixed to the adapter receiver 27 by a bayonet 32 in a fitted state.

The adapter main body 28 has an insertion hole 33 inside thereof through which a treatment instrument is inserted and removed and suction is performed, and a substantially cylindrical slider 34 is installed inside this insertion hole 33. It can be slid up and down along the inner surface of the insertion hole 33.

Further, a protrusion 35 that protrudes laterally is provided on the outer surface of the upper end of the slider 34, and this protrusion 35 moves up and down within a groove 36 formed on the inner surface of the adapter body 28.
When the cap 37, which will be described later, is opened, the cap 37 is stopped against a stopper part 38 formed at the upper end of the groove part 36, as shown in FIG.

That is, the slider 34 is pushed up by a return coil spring 39, which is wound around the outer periphery of the slider 34 in the groove 36, hits the lower surface of the projection 35, and is pushed up from below. slider 3
4.

The outer end of the slider 34 is formed with a relatively small-diameter insertion opening 41 through which a treatment instrument, such as forceps 40, is inserted, so that a gap is created as little as possible when the forceps 40 is inserted.

Furthermore, the above-mentioned rubber cap 37 is fitted onto the outer end of the adapter body 28.

That is, the cap 37 is tightly fitted and engaged with the flange edge 42 of the adapter body 28 by utilizing its elasticity, and is detachably fitted. A truncated conical protrusion 4 protruding toward the mouth 41 side
3 is integrally formed, and when it is fitted as shown in FIG. 2, the slider 34 is pushed in by its protrusion 43.

That is, when the cap 37 is closed, the slider 34 is pushed in, and when the cap 37 is opened, the slider 34 is "protruded".

The slider 34 is formed with a communication port 46 that matches the connection port 45 of the second adapter connection pipe 44 when the slider 34 is pushed in. The two adapter connecting pipes 44 are made to communicate with each other.

Further, when the cap 37 is removed and the slider 34 is raised, the communication port 46 is shifted from the connection port 45 and closed.

On the other hand, the second adapter connecting pipe 44 is connected to the first adapter connecting pipe 48 via a rubber connector 47, which will be described later.

That is, the connector 47 inserts and fits the tip of the first adapter connecting pipe 48, and is normally connected in a fixed manner so that it cannot be removed.

Of course, since it is fitted, it can also be removed.

Furthermore, a communication port 50 that opens into the cavity 49 in the connector 47 is formed on the side surface of the insertion side tip of the first adapter connecting pipe 48 .

Furthermore, the connector 47 is formed with a connection socket 51 into which the tip of the second adapter connecting pipe 44 is inserted and fitted, and the tip of the pipe 44 is inserted into the socket 51. For example, connect the tip of the connecting pipe 44 to the connector 4.
7 and can communicate with each other.

Further, when the tip of the connecting pipe 44 is pushed into the socket 51, it is easily contracted due to the elasticity of both, and can be elastically fitted.

That is, the second adapter connection pipe 44 can be easily attached to and detached from the socket 51 of the connector 47.

Note that the first adapter connection pipe 48 is connected to a connection port 5 that opens on the inner wall surface of the ventilation hole 20 of the first adapter section 4.
Connected to 2.

In other words, the first adapter connection pipe 48 is connected to the ventilation hole 20.
It communicates with the bottom of the.

A connection port 54 to which a suction pipe 53 is connected is provided on the bottom side surface of the ventilation hole 20 .

At the bottom of the ventilation hole 20, there are connection ports 52 for connecting the first adapter connection pipe 48 and the suction pipe 53.
．． 54 and a communication hole 21 communicating with the injection hole 12, respectively, so as to communicate with each other.

Further, the suction pipe 53 is connected to a suction tube 56 via a tube connection cap 55 at its tip, and the suction tube 56 is connected to a suction device (not shown).

Furthermore, the connector 47 is located in the middle of the suction pipe 53.
It is fitted and held in a mounting groove 57 which is shaped like this.

That is, each connecting pipe 44 . 48 and the suction pipe 53 are held together by a connector 47 so as not to come apart.

Next, each usage state will be explained.

First, FIG. 3 shows a state in which suction is simultaneously carried out through both channels 9 and 30.

That is, while simultaneously closing the openings 24 and 25 of the first adapter part 4 with the palm of the finger 26, the second adapter part 5
By covering the cap 37 and closing the insertion port 41, the channels 9 and 30 are airtightly communicated with the ventilation hole 20.

Therefore, if a suction action is applied to the ventilation hole 20 through the suction pipe 53, suction can be drawn from the injection hole 12 and the first channel 9 through the communication hole 21 in the first adapter section 4. At the same time, the second adapter part 5
In this case, suction can be carried out from the second channel 30 through the connecting pipe 48, the connector 47, the connecting pipe 44, the communication port 46, and the insertion hole 33.

FIG. 4 shows a case where only the first channel 9 is suctioned, and in this case, the cap 37 of the second adapter part 5 is removed and the opening 2 of the first adapter part 4 is removed.
4.25 with the palm of the finger 26 at the same time.

That is, in order to remove the cap 37 of the second adapter section 5, the slider 34 is pushed up by the coil spring 39, hits the stopper section 38, and stops.

Therefore, the communication port 46 of the slider 34 is connected to the connection port 45.
Since the connection port 45 is closed by the slider 34, it is airtight with respect to the ventilation hole 20.

Therefore, only the first channel 9 can be suctioned, and a treatment tool such as forceps 40 can be inserted through the insertion hole 33 and the second channel 30 in the second adapter part 5 regardless of the suction operation. Can be done independently.

That is, in this case, air leakage in the second adapter section 5 is completely eliminated.

Note that when suction is also performed through this second channel 30, by fitting the cap 37 as described above, the insertion port 41 is completely closed by the cap 37, and the communication port 46 is connected. Since it communicates with the opening 45 and the vent hole 20, it is possible to provide a suction effect as described above.

Further, FIG. 5 shows a state in which a chemical solution is injected through the first channel 9, and the injection port 1 of the first adapter section 4 is injected.
When the syringe 13 is attached to the syringe 4, the lowering of the slider 15 closes the communication port 21 and blocks it from the ventilation hole 20 side.

Therefore, when injecting the drug, it is possible to inject only through the first channel 9 without causing leakage to the suction tube 53 side.

In the above embodiment, the adapter bodies 7 and 28 of the respective adapter parts 4 and 5 are configured to be removable from the operation part main body 1 together with other members. Pipes 44, 48 are connected via connectors 47.

The second adapter connecting pipe 44 can be easily attached and detached from the connector 47.

That is, the tip of the second adapter connection pipe 44 can be easily connected to the socket 51 of the connector 47 by simply inserting and fitting it.

In addition, the suction circuit is formed by connecting the connecting pipes 44 and 48 via the connector 47, without individually connecting the suction pipes 53 to each of the adapter parts 4 and 5. .

Therefore, the structure of the suction system can be simplified and the suction circuit can be connected with one touch using the connector 47.

As explained above, the present invention allows each adapter section to be detachably attached to the operating section body of an endoscope, and to connect each adapter section with each other to construct one suction circuit. Each suction connecting pipe connected to the hole in the adapter part is connected removably by a connector. Therefore, each adapter part can be connected and disconnected independently, and each connecting pipe can be easily connected. The suction circuit can be configured by

That is, the mounting operation can be performed quickly and easily.

Furthermore, since each connecting pipe can be easily separated, it is also easy to remove them, which is convenient for cleaning and disinfecting the suction control device section.
