The underwater penetration (10.7cm-16.3cm, the internal pressure 8-12 millimetres of mercury of corresponding endoscope-assistant surgery) of pressure regulation tube 2, thus
Mass rate of emission and body intracavity pressure are adjusted, is applied to closed body cavity at this time.
And the sorption channel of massive texture clamping stagnation aspirator 1 in order to prevent, while in order to promote the absorption of 1 end of aspirator
Efficiency, the input terminal of aspirator 1 are spherical or ellipsoid the adsorption head of expansion, which is evenly equipped with multiple suction holes
36, to guarantee that internal flue gas or internal liquid can enter from all directions of aspirator 1, adsorption efficiency is improved, is kept away
Exempt from the damage to in-vivo tissue or adsorbs the blocking of people having a common goal.
Embodiment two:
In the present embodiment, as shown in figure 5, it is used be the liquid level of liquid 5 move up and down, regulation pipe 2 it is motionless
Mode, wherein pressure adjusts and is provided with liquid level adjusting mechanism on bottle 4, and liquid level adjusting mechanism includes a sliding casing 13 and piston
14, the lower end for slipping casing 13 extends to the bottom that pressure adjusts bottle 4, and piston 14 is arranged along sliding casing 13 and slides up and down
So that the liquid level that pressure adjusts liquid 5 in bottle 4 rises or falls, concrete principle is: when piston 14 moves downward, 14 meeting of piston
The liquid 5 in sliding casing 13 is discharged, liquid 5 is discharged from the hole of sliding 13 bottom of casing, adjusts in bottle 4 so as to cause pressure
Liquid level rises, and same regulation pipe 2 can submerge liquid 5, and the height by adjusting liquid level is the discharge speed of adjustable aspirator 1
Degree, regulation pipe 2 submerge it is deeper, discharge it is slower, submerge it is more shallow, discharge it is faster, when breather valve 32 close when, be converted to common suction
Device active negative-pressure ward function, and realize maximum negative-pressure ward.
Specifically, in the present embodiment, liquid level adjusting mechanism further includes solenoid valve 15 and is arranged in sliding casing 13
Spring 16, sliding casing 13 is fixed in by screw 30 to be adjusted on bottle cap 24, the top of one end of spring 16 and sliding casing 13
Portion's connection, the other end are connect with piston 14, and the top of sliding casing 13 is provided with positive pressure interface 17, positive pressure interface 17 and solenoid valve
15 connections, wherein positive pressure interface 17 can be connect with the positive pressure connector of hospital, convenient and efficient, and when the closing of solenoid valve 15, it can
To play the pressure maintaining effect that pressure adjusts bottle 4.
Likewise, in the present embodiment, negative port 6 and pressure adjust and are additionally provided with filter 18, filter between bottle 4
18 upper end is provided with threaded strainer cover 33, and strainer cover 33 and filter 18 pass through the removable sealed connection of screw thread,
Be provided with negative port 6 on strainer cover 33, be provided with the filter core 34 that can be replaced in filter 18, filter core 34 include sponge and
Active carbon, the smoke particle of intraperitoneal generation when for adsorbing operation.
