BRIEF DESCRIPTION OF THE DRAWINGS

[0023] FIG. 1 is a schematic structural diagram of Embodiment 1;

[0024] FIG. 2 is a schematic structural diagram of Embodiment 2; and

[0025] FIG. 3 is a schematic structural diagram of Embodiment 3.

DETAILED DESCRIPTION

[0026] The present disclosure will be further described below with reference to the drawings and embodiments.

[0027] As shown in FIGS. 1 to 3, the present disclosure comprises a host computer 1, an irrigation tube 2, a check valve 3, a tee joint 4, an aspiration tube 5, a negative pressure aspiration device, a pump 6, an electronic choke device 7, an irrigation and aspiration common tube 8, and a terminal execution device. In an embodiment, a pump 6 is disposed on the irrigation tube 2 for delivering the irrigation fluid, and the pump 6 is preferably a peristaltic pump. One end of the irrigation tube 2 is connected to an irrigation fluid container (not shown in the figures), and the other end of the irrigation tube 2 is connected in series with the check valve 3 and then connected with the first port of the tee joint 4. Preferably, the tee joint 4 has a “T” shape, and a check valve 3 is installed at the first port of the tee joint 4, and the second port and the third port of the tee joint 4 are located on a straight line. The second port of the tee joint 4 is connected to the suction, tube of the negative pressure device through the aspiration tube 5. An electronic choke device 7 is installed on the aspiration tube 5. The electronic choke device 7 is preferably an electronic tube clip. The third port of the tee joint 4 is connected with an irrigation and aspiration common tube 8 which is also connected to a terminal execution device.

[0028] As shown in FIGS. 1 to 3, the electronic choke device 7 and the pump 6 are both controlled by the host computer 1. The electronic choke device 7 is turned off when the pump 6 works; the pump 6 is stopped when the electronic choke device 7 is turned on. Preferably, the electronic choke device 7 is controlled by the first delayer provided in the host computer 1 and may be turned off in a delayed manner. The host computer 1 is provided with a first selection rotary knob 9 by which the turn-off of the electronic choke device 7 is delayed. The first selection rotary knob 9 has a plurality of tap positions. For instance: the first selection rotary knob has 4 tap positions, with the shortest time being 0 seconds, and the longest time being 3 seconds. The pump 6 is controlled by an automatic controller provided in the host computer 1. When the turn-off of the electronic choke device 7 is delayed, the pump 6 is automatically turned on to irrigate for a certain period, and the irrigation time is controlled by the second delayer provided in the host computer 1. The host computer 1 is provided with a second selection rotary knob 10 that controls the automatic irrigation time after the turn-off of the electronic choke device 7 is delayed. The second selection rotary knob 9 has multiple tap positions. For instance, the second selection rotary knob has 5 tap positions, with the shortest time being 0 seconds, and the longest time being 4 seconds.

[0029] According to different terminal execution devices, the present disclosure has various variations, specifically as follows:

EMBODIMENT 1

[0030] As shown in FIG. 1, this embodiment improves the function of the existing gastrointestinal endoscopes. The terminal execution device is a gastrointestinal endoscope 11 of which a suction port is connected to the irrigation and aspiration common tube 8. The startup and stop of the pump 6 is controlled by the foot pedal 13. A wireless or wired button 12, which replaces the original gastrointestinal endoscope suction button and is installed in the original location, is provided to control the turn-on and turn-off of the electronic choke device 7, and the wireless or wired button 12 seals this location of the gastrointestinal endoscope 11 and keeps the suction channel unobstructed.

[0031] The working principle of embodiment 1 is as follows:

[0032] The delayed turn-off time is set by the first selection rotary knob 9, and the pre-lavage time is set by the second selection rotary knob 10. The medical staff holds the handle of the gastrointestinal endoscope 11 and presses the wireless or wired button 12 to turn on the electronic choke device 7, and stop the pump 6, and thus the aspiration function is achieved under the action of the negative pressure device. When the aspiration is completed, the wireless or wired button 12 is released, and the electronic choke device 7 continues to be turned on for a certain period of time until the negative pressure device automatically stops working; at this time, the pump 6 automatically starts, so that the irrigation fluid passes through the irrigation tube 2 and the irrigation and aspiration common tube 8 sequentially, and then enters the irrigation and aspiration common channel of the gastrointestinal endoscope 11 to realize pre-irrigation, the pump 6 automatically stops after it works for a few seconds; in order to achieve continuous irrigation and lavage, the foot pedal 13 is pressed so that the pump 6 continue to work.

EMBODIMENT 2

[0033] As shown in FIG. 2, this embodiment relates to novel gastric lavage machine, and the terminal execution device is a gastric lavage tube 14. An electronic suction button 15 that controls the turn-on and turn-off of the electronic choke device 7 is installed on the host computer 1, and an electronic irrigation button 16 that controls the startup and stop of the pump 6 is also installed on the host computer 1. The working principle of irrigation and aspiration in this embodiment is the same as that in Embodiment 1, so details are not described herein.

EMBODIMENT 3

[0034] As shown in FIG. 3, this embodiment is used for irrigation and aspiration of minimally invasive surgery, and the terminal execution device is a surgical instrument 17. An electronic suction button 15 that controls the turn-on and turn-off of the electronic choke device 7 is installed on the surgical instrument 17, and an electronic irrigation button 16 that controls the startup and stop of the pump 6 is also installed on the surgical instrument 17. The working principle of irrigation and aspiration in this embodiment is the same as that in Embodiment 1, so details are not described herein.
