Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] Reference Figure 1-Figure 5 As shown, this embodiment provides a specific implementation method for a negative pressure airflow control system of an electronic proctoscope, including a handle housing 10, wherein the handle housing 10 includes a handheld portion 101 and a horizontal portion 102, wherein the handheld portion 101 is obliquely arranged at the rear end of the horizontal portion 102;

[0029] It also includes a negative pressure air inlet pipe 20, a solenoid valve 30, a micro switch 40, a negative pressure air outlet pipe 50, and a trigger 60. The micro switch 40 is located at the inner corner of the handheld portion 101 and the horizontal portion 102. The trigger 60 is rotatably connected to the inner corner of the handheld portion 101 and the horizontal portion 102, and moves to squeeze the micro switch 40, so that the solenoid valve 30 located next to the micro switch 40 is powered on or powered off and stops working.

[0030] One end of the solenoid valve 30 is connected to a negative pressure air inlet pipe 20 , which is located inside the handheld portion 101 . The other end of the solenoid valve 30 is connected to a negative pressure air outlet pipe 50 , which is located inside the horizontal portion 102 .

[0031] Furthermore, the solenoid valve 30 and the micro switch 40 are electrically connected.

[0032] Furthermore, the head end of the negative pressure outlet pipe 50 is connected to the negative pressure interface of the anorectal ligation device.

[0033] Furthermore, the end of the negative pressure air inlet pipe 20 that is not connected to the solenoid valve 30 extends out from the bottom of the handheld part 101 and is connected to the negative pressure suction device, and a pressure relief pipe 70 is arranged next to the other end of the negative pressure air inlet pipe 20, so that a three-fork channel is formed at this end of the negative pressure air inlet pipe 20.

[0034] The utility model connects the end of the negative pressure air inlet pipe 20 exposed at the bottom of the handheld part 101 to an external medical negative pressure aspirator. When the trigger 60 is not activated, the solenoid valve 30 does not work, the negative pressure cannot pass, the anorectal ligation device is in a normal pressure-free state, and the three-pronged channel is in a pressure relief state.

[0035] The trigger 60 turns on the micro switch 40 and the electromagnetic valve 30. The negative pressure airflow passes through the electromagnetic valve 30 and enters the negative pressure outlet pipe 50 and then connects to the negative pressure interface of the anorectal ligation device, so that the end of the anorectal ligation device generates suction negative pressure.

[0036] The handle controls the micro switch 40 to control the solenoid valve 30. The operator has an obvious hand feeling, strong micro-sensitivity, and precise control. No matter whether the external negative pressure suction device is turned on or off, it only needs to control the trigger 60.

[0037] As a possible specific implementation of the utility model, the trigger 60 includes a pulling part 601 and a triggering part 602, and the pulling part 601 and the triggering part 602 are integrated. The pulling part 601 is rotatably connected to the inner wall of the handle housing 10 through rivets. The triggering part 602 and the micro switch 40 touch or separate, so that the trigger 60 connects the micro switch 40, prompting the solenoid valve 30 to be powered on or powered off to stop working.

[0038] Furthermore, a protrusion 603 is vertically provided on the side of the trigger portion 602 facing the micro switch 40, and a reset spring 604 is mounted on the protrusion 603. The other end of the reset spring 604 abuts against a fixing portion 605, and the fixing portion 605 is fixed to the inside of the handle housing 10 by bolts.

[0039] Furthermore, the solenoid valve 30 is a three-way solenoid valve, and the main function of the three-way solenoid valve is to control the flow of gas and liquid, allowing the flow direction and flow rate of the medium to be adjusted, thereby achieving precise control of the flow direction of the negative pressure gas.

[0040] As a possible specific implementation of the present invention, the other side of the trigger portion 602 away from the micro switch 40 is a rounded arc-shaped concave surface, which conforms to ergonomics, significantly improves the operator's experience, and saves more effort.

[0041] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
