[0027] The present utility model will now be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only schematically showing the basic structure of the present utility model. Therefore, they only show the components related to the present utility model, and directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalents.

[0028] Embodiment 1:

[0029] As Figure 1 - Figure 3 shown, a self-cleaning negative pressure mechanism of an electric ligator, the ligator includes a housing 1 and a negative pressure mechanism located inside the housing 1, and is characterized in that: the negative pressure mechanism includes:

[0030] A negative pressure generating device 2, which can be a negative pressure pump, having an air inlet 201 and an air outlet 202;

[0031] An air suction pipe 3, the front end of which is facing the lesion site for adsorbing the lesion site, and the rear end of which is communicated with the air inlet 201 of the negative pressure generating device 2;

[0032] And an air outlet pipe 4, the front end of which is communicated with the air outlet 202 of the negative pressure generating device 2, and the rear end of which is inserted into an absorbent body 5 for absorbing the liquid flowing out therein.

[0033] When the negative pressure generating device 2 is started, the air suction pipe 3 starts to suck air to suck the lesion site, and at the same time, the air outlet pipe 4 discharges the inhaled gas. When a small amount of blood and water enters the air outlet pipe 4 from the air suction pipe 3 under the action of suction, the absorbent body 5 can absorb the small amount of blood and water mixed in the gas, thereby preventing the short circuit of the circuit caused by the diffusion of blood and water everywhere.

[0034] In some examples, the air outlet pipe 4 includes a first branch pipe 401 communicated with the air outlet 202 and a second branch pipe 402 bent downward from the rear end of the first branch pipe 401. A handle 101 is provided at the bottom of the housing 1, and the second branch pipe 402 is located inside the handle 101 and extends along the direction of the handle 101. The downward extending second branch pipe 402 can make the blood and water in it completely enter the absorbent body 5 under the action of gravity and thus be completely absorbed by the absorbent body 5, avoiding the remaining blood and water dripping into the inside of the housing 1 during the flipping process of the ligator.

[0035] In some examples, a housing 6 for installing a power source is fixedly provided inside the handle 101. The power source is located inside the housing 6 and is enclosed. The absorber 5 is clamped between the inner wall of the handle 101 and the outer wall of the housing 6 to limit the lateral position of the absorber 5. The absorber 5 is provided with an insertion hole 501 for inserting the air outlet pipe 4. The air outlet pipe 4 is inserted into the insertion hole 501 so that the blood and water inside it completely flow into the absorber 5. The insertion hole 501 is not through, that is, the air outlet pipe 4 does not extend downward out of the absorber 5.

[0036] In some examples, a plurality of positioning plates 1013 for positioning the air outlet pipe 4 are provided inside the handle 101. The plurality of positioning plates 1013 are spaced apart along the extending direction of the handle 101. Each positioning plate 1013 is provided with a positioning hole 1014 for inserting the air outlet pipe 4. The plurality of positioning holes 1014 fix the position of the air outlet pipe 4 to prevent it from shaking during the exhaust process.

[0037] In some examples, an upper limiting member 1011 and a lower limiting member 1012 for limiting the absorber 5 are provided inside the handle 101. The absorber 5 is located between the upper limiting member 1011 and the lower limiting member 1012 to limit the longitudinal position of the absorber 5. The upper limiting member 1011 can also be used as the lowermost positioning plate 1013. The lower limiting member 1012 can be a connecting portion that connects two half-shells to form a complete outer shell. The connecting portion protrudes inside the half-shell to support and limit the absorber 5 located inside the outer shell from below.

[0038] In some examples, the absorber 5 is a water-absorbing sponge, and can also be a water-absorbing material such as a water-absorbing cotton strip. It only needs to satisfy allowing gas to pass through while blocking liquid from passing through, and intercepting and absorbing the liquid.

[0039] In some examples, an electric ligator includes the above self-cleaning negative pressure mechanism. A display screen 7 is provided at the rear end of its outer shell 1. The display screen 7 is inclined backward from top to bottom, and the included angle between it and the horizontal plane is α, 90° < α < 130°. The inclined setting of the display screen 7 is more ergonomic, and the inclined display screen 7 can obtain a larger display surface, which is beneficial for the operator to observe the information on the display screen 7 during the operation.

[0040] Working principle:

[0041] Start the negative pressure generating device 2. The suction pipe 3 starts to suck air to suck the lesion site. At the same time, the air outlet pipe 4 discharges the inhaled gas. When a small amount of blood and water enters the air outlet pipe 4 from the suction pipe 3 under the action of suction, the absorber 5 can intercept and absorb the small amount of blood and water mixed in the gas, realizing self-cleaning during the external discharge process of the air outlet pipe 4, thereby avoiding short circuits caused by the spread of blood and water everywhere.

[0042] Based on the above inspiration from the ideal embodiments of the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
