Shown in Fig. 3, this utility model embodiment provides a kind of hepatobiliary drainage device, comprises drainage tube 10, negative-pressure adsorption device and syringe pipe 30.
Specifically, the inflatable spring cylinder 13 that drainage tube 10 comprises mozzle 11, conical head 12 and is arranged between the front end of described mozzle 11 and described conical head 12, described conical head 12 connects a control line 14, described control line 14 forms an exit through described inflatable spring cylinder 13 by the rear end extraction of described mozzle 11, when applying a pulling force at described exit, described inflatable spring cylinder 13 compresses vertically and radially expands; Described inflatable spring cylinder 13 is connected with described mozzle 11, and described inflatable spring cylinder 13 is provided with conduction hole 131.
That is, the conduction hole 131 that inflatable spring cylinder 13 surface is arranged to for being introduced in inflatable spring cylinder 13 by the hydrops in liver and gall, then is excreted by the mozzle 11 that inflatable spring cylinder 13 rear end connects.And this inflatable spring cylinder 13 can compression-expansion.Corresponding, control line 14 is for controlling inflatable spring cylinder 13 expansion change, concrete, by applying pulling force to control line 14, this pulling force acts on conical head 12, force conical head 12 move backward and extrude inflatable spring cylinder 13, make inflatable spring cylinder 13 be compressed and expand laterally.And when removing the pulling force to control line 14 applying, because inflatable spring cylinder 13 has elasticity, therefore, original state can be returned to, the naturalness that original state is namely close with the diameter of mozzle 11.
Negative-pressure adsorption device comprises liquid storage container 20 and for described liquid storage container 20 evacuation is with the negative pressure generator 21 making described liquid storage container 20 inside form negative pressure, described liquid storage container 20 is connected with the rear end of described mozzle 11.
That is, liquid storage container 20 is connected with mozzle 11, for collecting the hydrops that mozzle 11 is discharged.Negative pressure generator 21 is then for liquid storage container 20 evacuation, negative pressure is formed in liquid storage container 20, so, hydrops in liquid storage container 20 pairs of mozzles 11 produces negative-pressure adsorption effect, hydrops around inflatable spring cylinder 13 can be sucked into fast in mozzle 11, finally, in mozzle 11, be expelled to liquid storage container 20, to reach the effect of quick drainage.
Syringe pipe 30 is arranged in described mozzle 11, and one end of described syringe pipe 30 stretches in described inflatable spring cylinder 13, and the other end passes from the rear end of described mozzle 11.
Owing to being provided with conduction hole 131 on inflatable spring cylinder 13 surface, when negative-pressure adsorption, hydrops around inflatable spring cylinder 13 is sucked in inflatable spring cylinder 13 from conduction hole 131, after long-time use, the hydrops with certain viscosity may be formed in inflatable spring cylinder 13, so, cause discharge opeing portion in inflatable spring cylinder 13 or even mozzle 11 unobstructed.In this utility model, this syringe pipe 30 for passing into flushing liquor in inflatable spring cylinder 13, flushing liquor can rinse in inflatable spring cylinder 13, so, can make can not form viscosity hydrops in inflatable spring cylinder 13, guarantee that mozzle 11 discharge opeing is smooth and easy, improve drainage effect.
According to the hepatobiliary drainage device that this utility model embodiment provides, the state of inflatable spring cylinder 13 can be controlled by control line 14, after drainage tube 10 is inserted in liver and gall, pulling force can be applied to control line 14, inflatable spring cylinder 13 is forced to become swelling state, so, the problems such as drainage tube 10 slippage can be avoided.In addition, can by flushing liquor in inflatable spring cylinder 13 in syringe pipe 30, so, hydrops in inflatable spring cylinder 13 can be rinsed, thus make inflatable spring cylinder 13 inwall there is no viscosity hydrops, guarantee that drain is unimpeded, there is better drainage effect.
In an embodiment of the present utility model, described one end of syringe pipe 30 is provided with a shower nozzle 301, and described shower nozzle 301 is provided with multiple spray holes circumferentially.So, utilize shower nozzle 301 to jet douche liquid in inflatable spring cylinder 13, the viscosity hydrops etc. that attachment is stronger can be rinsed, to improve the effect of flushing.
In a preferred embodiment of the present utility model, also comprise fluid supplier, this fluid supplier comprises liquid containing bottle 32 and elasticity extruding sacculus 31, and described elasticity extruding sacculus 31 has the inlet 311 be communicated with described liquid containing bottle 32 and the liquid outlet 312 be communicated with the described other end of described syringe pipe 30.That is, the inlet 311 of elasticity extruding sacculus 31 is communicated with liquid containing bottle 32, and the liquid outlet 312 of elasticity extruding sacculus 31 is communicated with syringe pipe 30.
Inlet 311 is provided with the first check valve 33, described first check valve 33 leads to the direction conducting of described elasticity extruding sacculus 31 along described liquid containing bottle 32, described liquid outlet 312 is provided with the second check valve 34, and described second check valve 34 leads to the direction conducting of described syringe pipe 30 along described elasticity extruding sacculus 31.
When extruding elasticity extruding sacculus 31, the flushing liquor in elasticity extruding sacculus 31 is expelled to syringe pipe 30 by the second check valve 34, then delivers to shower nozzle 301 through syringe pipe 30, finally sprays from shower nozzle 301.And when unclamping elasticity extruding sacculus 31, elasticity extruding sacculus 31 recovers deformation, the flushing liquor in liquid containing bottle 32 is entered in elasticity extruding sacculus 31 by the first check valve 33.So, can realize repeatedly extruding and flushing liquor being clamp-oned to syringe pipe 30 and sprayed by shower nozzle 301.
In the present embodiment, adopt the fluid supplier of said structure, with fashion of extrusion ejection flushing liquor, it is easy to operate, and meanwhile, the fluid pressure of injection is large, and developing result is good.This external structure is simple.
In a preferred embodiment of the present utility model, the appearance of inflatable spring cylinder 13 is provided with one deck and filters protecting film 132.Because the hydrops in liver and gall may block the conduction hole 131 on inflatable spring cylinder 13, so, in the present embodiment; one deck is set by the upper surface of inflatable spring cylinder 13 again and filters protective layer; can the larger tissue substance etc. of filter diameter, avoid blocking conduction hole 131, guarantee that drain is smooth and easy.
