The specific embodiment
By describing technology contents of the present invention in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
The design of most critical of the present invention is: the direction of improving the flushing outlet of irrigating catheter realizes back flush and goes out foreign body, reaches better developing result.
Refer to Fig. 1 and Fig. 2, a kind of irrigating catheter, comprise catheter body 100, the two ends of described catheter body are respectively 10He operating side, working end 20, on the tube wall of described working end 10, be provided with at least one flushing liquor outlet 11, the interior flushing liquor exit passageway 12 for connecting tube body interior 101 and described flushing liquor outlet 11 of tube wall is towards the direction setting that deviates from working end end 13, between flushing liquor outlet 11 and working end end 13, be provided with developing ring 14, described operating side 20 enters mouthpart 21 with flushing liquor and is connected, described flushing liquor enters mouthpart 21 and is communicated with by the syringe pipe 110 being placed in catheter body 100 with flushing liquor outlet 11.
From foregoing description, beneficial effect of the present invention is: developing ring can demonstrate position and the degree of depth at irrigating catheter place under the perspective of X ray, thereby the flushing liquor exit passageway that deviates from working end end in the tube wall of catheter body by arranging makes flushing liquor from flushing liquor, export reverse ejaculation through this passage, the flushing liquor of reverse ejaculation can stretch into foreign body direction towards irrigating catheter is gone out, reach good developing result, and can reduce the damage to liver and vermiform appendix in operation.
Further, flushing liquor exit passageway 12 is barb-shaped, and the direction of its barb deviates from working end end 13.
Seen from the above description, flushing liquor exit passageway is set to barb-shapedly be conducive to flushing liquor reverse ejaculation from syringe pipe, thus the direction that foreign body is stretched into towards irrigating catheter go out, improve surgical effect.
Further, working end end 13 is provided with seal wire outlet 15, and operating side 20 is connected with seal wire and enters mouthpart 22, and seal wire outlet 15 enters between mouthpart 22 and is communicated with by the wire leading pipe 120 being placed in catheter body 100 with seal wire.
Seen from the above description, the effect of seal wire is the effect of playing guiding, and for example, after certain branch that seal wire wafts in human body viscera (, seal wire enters the branch that has microlith in left liver or right liver), irrigating catheter follows up to branch and rinses outward.
Further, flushing liquor outlet 11 is provided with two or three.
Seen from the above description, two or three flushing liquor outlets are set and just can make this device two or three directions be rinsed in the pipeline of human organ simultaneously, be conducive to improve developing result.
Further, developing ring 14 is socketed on the tube wall outside of catheter body 100.
Further, flushing liquor enters mouthpart 21 and is connected with the opening that is positioned at operating side end 24 places by female Luer 23.
Please refer to Fig. 1 and Fig. 2, embodiments of the invention are: a kind of irrigating catheter, comprise catheter body 100, and the two ends of catheter body are respectively 10He operating side, working end 20.
On the tube wall of working end 10, be provided with a plurality of flushing liquor outlets 11, the interior flushing liquor exit passageway 12 for connecting tube body interior 101 and flushing liquor outlet 11 of tube wall is towards the direction setting that deviates from working end end 13, flushing liquor exit passageway 12 is barb-shaped, the direction of its barb deviates from working end end 13, between flushing liquor outlet 11 and working end end 13, be provided with developing ring 14, developing ring 14 is socketed on the tube wall outside of catheter body 100.
Operating side 20 is connected with a flushing liquor and enters mouthpart 21, flushing liquor enters mouthpart 21 and is connected with the opening that is positioned at operating side end 24 places by female Luer 23, flushing liquor enters mouthpart 21 and is communicated with (for to distinguish with other lines by the syringe pipe 110 being placed in catheter body 100 with flushing liquor outlet 11, syringe pipe 110 in Fig. 1 has been stamped horizontal hatching, not represents that syringe pipe 110 is for solid construction).
Working end end 13 is provided with seal wire outlet 15, operating side 20 is connected with seal wire and enters mouthpart 22, seal wire outlet 15 enters between mouthpart 22 and is communicated with (for to distinguish with other lines by the wire leading pipe 120 being placed in catheter body 100 with seal wire, wire leading pipe 120 in Fig. 1 has been stamped cruciform cross-section line, not represents that wire leading pipe 120 is for solid construction).
In use, working end 10 is stretched into patient's affected area, then flushing liquor being entered to mouthpart 21 from flushing liquor imports, flushing liquor flows to 10 places, working end along syringe pipe 110, because the end of syringe pipe 110 is communicated with flushing liquor outlet 11, therefore the end of syringe pipe 110 is placed in flushing liquor exit passageway 12 and is also converted into barb-shaped, flushing liquor from syringe pipe 110 after flushing liquor outlet 11 is gone out, along the direction shown in arrow in Fig. 2 is reverse, inject in tube chamber, thereby intraluminal foreign body is rushed to the direction that irrigating catheter stretches into, realize best developing result.And the flushing liquor of traditional irrigating catheter is generally (the going out from seal wire outlet 15) of going out towards the below of Fig. 2, although can play the effect of cleaning focus, but if intralesional exists the foreign bodies such as calculus, gallbladder mud, pus or gastrolith, there is the more depths of foreign body being poured to tube chamber in such flushing.
To sum up, flushing conducting provided by the invention is crossed the direction that foreign body that the flushing liquor that produces reverse ejaculation can be positioned at the pipeline that is positioned at human organ diverse location stretches into towards irrigating catheter and is gone out, reach good developing result, and can reduce the damage to liver and vermiform appendix in operation.The application's scheme, except being applicable to cholangiopancreatography, is also applicable to common bile duct, vermiform appendix and various sinus tract to rinse.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalents of utilizing description of the present invention and accompanying drawing content to do, or be directly or indirectly used in relevant technical field, be all in like manner included in scope of patent protection of the present invention.
