Referring to FIG. 2 , the smoking pipeline 1 of the present invention is arranged parallel to the instrument pipeline 5 of the endoscopic instrument. The smoking line 1 can be arranged parallel to the instrument line 5 of the endoscopic instrument in any suitable manner. For example, the smoking pipe 1 and the instrument pipe 5 can be fixed together by a plurality of locking straps arranged along the length of the pipe. A plurality of C-shaped elastic buckles can also be provided on the outside of the smoking pipe 1 . When the smoking pipeline 1 is compressed and fixed on the instrument pipeline 5 in parallel, the opening of the C-shaped elastic buckle is elastically opened, and is buckled on the instrument pipeline 5 , and then elastically hugs the instrument pipeline 5 .

In Fig. 2, the right end is the end (outer end) away from the human body, and the left end is the end (inner end) extending into the body cavity of the human body. That is to say, when exhausting or smoking, the smoke generated in the body cavity flows from left to right in the smoking pipeline 1 . When liquids such as cleaning liquid are injected into the body cavity, the external liquid flows from right to left in the smoking pipeline 1 .

Referring to FIG. 2 , a connection tee 2 is provided at the right end (outer end) of the smoking pipe 1 . The first branch connecting the tee 2 (the branch extending downward in FIG. 2 ) communicates with the smoking pipeline 1 . The second branch connecting the tee 2 (the branch extending to the left in Fig. 2) limits the suction port 21, and the suction port 21 is communicated with the exhaust pipe 3 for discharging the smog in the body cavity; Used to drain fluid from body cavities. The third branch connected to the tee 2 (the branch extending to the right in FIG. 2 ) defines a liquid supply port 22 , and the liquid supply port 22 communicates with the liquid inlet pipe 4 for receiving liquid from the liquid inlet pipe 4 .

It should be pointed out that the shape, structure and position of the connection tee 2 are not limited to those shown in the figure. For example, the connecting tee 2 can be integrated on the smoking pipe 1 .

Two ends of the exhaust pipe 3 are respectively a first joint 31 and a second joint 32 . The first joint 31 is connected to the suction port 21 of the connection tee 2 . The second joint 32 is connected with the suction device. Use the negative pressure provided by the aspirator to suck the smoke in the body cavity. It can also be used to aspirate liquids in body cavities when needed. It can be understood that a flow rate regulating device or a switching device can be provided on the exhaust pipe 3 to adjust the suction speed and suction intensity. The second connection 32 can also be connected to an ERBE smoking module or other devices capable of venting smoke.

The two ends of the liquid inlet pipe 4 are respectively a third joint 41 and a fourth joint (specifically, a cork piercer 44 ). The third joint 41 is connected with the liquid supply port 22 of the connection tee 2 . The fourth connection is for example connected to a rinsing liquid container. In the illustrated embodiment, the fourth connector is embodied as a cork piercer 44 for insertion into a bottle containing irrigating fluid. In order to protect the cork piercer 44, a needle shield 45 is provided. When the cork piercer 44 is pulled out, the needle shield 45 is sleeved on the cork piercer 44 .

Referring to FIG. 2 , a three-way control valve 6 is provided at the connection tee 2 . The three-way control valve 6 is used to control whether the smoking pipe 1 communicates with the exhaust pipe 3 or communicates with the liquid inlet pipe 4 . It can be understood that the three-way control valve 6 can also prevent the smoking pipe 1 from communicating with the exhaust pipe and the liquid inlet pipe 4 .

Further, in the communicating state, the three-way control valve 6 can also be set to control the size of the opening where the smoking pipe 1 communicates with the exhaust pipe 3 , or the size of the opening that communicates with the liquid inlet pipe 4 . In this case, the three-way control valve 6 is used not only for connection selection control, but also for flow control.

The three-way control valve 6 can adopt any suitable structure. For example, a rotary valve can be used to control through the swing or rotation of the spool; a linear valve can also be used to control through the linear movement of the spool.

The three-way control valve 6 can adopt any suitable driving method. For example, electric control drive can be used, and manual drive can also be used. Advantageously, manual driving is adopted to simplify the overall structure and reduce costs.

In the embodiment shown in FIG. 5 , the three-way control valve 6 includes a dial knob 61 and a valve core 62 . The toggle 61 drives the spool 62 to move linearly left and right to realize flow control. The valve core 62 is arranged at the outer end of the smoking pipe 1 and can seal and slide in the smoking pipe 1 . Advantageously, a sealing member (for example, a sealing ring 63, see Fig. 5 and Fig. 6 ) is provided between the valve core 62 and the inner wall of the smoking pipe 1 .

Specifically, a suction port 21 and a liquid supply port 22 are provided on the smoking pipe 1 . The suction port 21 and the liquid supply port 22 are spaced apart in the axial direction. Advantageously, the direction of the suction port 21 and the liquid supply port 22 are opposite.

Two through holes are provided on the side wall of the valve core 62 : a first valve core hole 621 and a second valve core hole 622 . The first spool hole 621 and the second spool hole 622 are disposed facing each other, that is, the axes of the first spool hole 621 and the second spool hole 622 coincide with each other. The first spool hole 621 is used to align with the suction port 21, and the second spool hole 622 is used to align with the liquid supply port 22.

It can be understood that if the direction of the suction port 21 and the liquid supply port 22 provided on the smoking pipe 1 are the same, only one through hole may be provided on the side wall of the valve core 62 . This through hole is aligned with the suction port 21 and the liquid supply port 22 respectively when the spool 62 is in different axial positions.

In the embodiment shown in FIG. 8 , the smoking pipe 1 is sleeved on the radial outer periphery of the instrument pipe. This technical solution is also within the protection scope of the present utility model.

Advantageously, a developing strip is arranged on the side wall of the smoking pipe. Thereby, if debris of the smoking line occurs, it is easy to find said debris.

Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solution of the present utility model, rather than to limit it. Those of ordinary skill in the art should understand that: the technical solutions described in the foregoing embodiments can be modified, or equivalent replacements can be made to some of the technical features; these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the utility model The spirit and scope of the technical solutions of each embodiment.
