Description

A kind of operation flushing aspirator

Technical field

The present invention relates to a kind of suction pump, a kind of operation flushing aspirator particularly, it mainly is applicable in the abdominal cavity microtrauma operation, belongs to medical apparatus and instruments.

Background technology

Because in operation, the flushing tissue that operative site is not stopped and the suction waste liquid that does not stop are simultaneous, this just needs the apparatus of a flushing and the apparatus of a suction, two kinds of replacing uses that apparatus does not stop in use, in operation, cooperate suitable trouble like this, waste operating time simultaneously again; Prior, flushing liquor might flow to non-operative site owing to can not be sucked at once, causes infection to tissue, and more trouble is in the microtrauma operation, may not stop so hardly to change and uses, and brings very big inconvenience to operation.

The flush valve cover of clinical flushing aspirator all is the same with suction valve gap profile with the face color, so just there are not visual effect and feel effect, allow the doctor be difficult to understand fast the use of flushing aspirator, time has been grown the doctor and may forget flushing and the valve location that aspirates, and brings inconvenience to operation.

China Patent No. 2012101810492 discloses the patent of invention that a kind of name is called " the operation suction device of band illumination cleaning function ", although it has the attraction function, but it can only wash optical fiber head, and can not carry out I ﹠ A simultaneously to operative site, so it does not still overcome above-mentioned defective of the prior art.

China Patent No. 2011100865671 discloses the patent of invention that a kind of name is called " the built-in suction pump of laparoscopic surgery ", although it can organize flushing and suction waste liquid to operative site simultaneously, but it is that suction pump is placed on intraperitoneal all the time when performing the operation, and changes the drawback that apparatus was brought to reduce; So there is following shortcoming inevitably in it: during owing to use, the doctor must catch to hold and attract head to absorb oozing of blood and sepage with pliers, so the doctor is difficult to accomplish to get express developed, suction fast, this just might cause oozing of blood and sepage to infect non-operative site because not aspirating.

Summary of the invention

The objective of the invention is to overcome above shortcomings in the prior art, and provide a kind of structural design more reasonable, can organize the operation flushing aspirator of flushing and suction waste liquid simultaneously to operative site.

The present invention addresses the above problem the technical scheme that adopts: this operation is characterized in that with flushing aspirator: it comprises forward part and the rear section of mutual coupling, forward part comprises probe, tee T, conduit, vacuum suction pipe joint, flushing valve and suction valve, and the rear section comprises adapter, upper and lower conduit and upper and lower syringe needle; Described probe, tee T, conduit, adapter, upper and lower conduit and upper and lower syringe needle are arranged in order; The one side that described adapter and conduit face mutually is provided with two positions up and down at least, conduit with should about two location matches and be connected with one of them, the another side of adapter is connected with described upper and lower conduit respectively, and upper and lower conduit matches with conduit; Described probe, flushing valve and suction valve connect with three ends of tee T respectively, and conduit and vacuum suction pipe joint are fixed on the tee T.Make thus the present invention when needs wash, open flushing valve and organize flushing that aspirate valve and be in about state this moment; When needs suctions waste liquid, to open the suction valve and carry out the waste liquid suction, this moment, flushing valve was in closed condition, had guaranteed to wash to organize and can aspirate waste liquid.

One in flushing valve of the present invention or the suction valve is provided with boss, and this boss is connected with valve.To increase the feel effect, allow the doctor understand the use of flushing aspirator fast, and make the doctor can not forget the valve location of flushing and suction, bring convenience to operation.

The present invention is respectively arranged with upper and lower vessel clamp at described upper and lower conduit.So that control flushing speed and pumping velocity.

The present invention compared with prior art has the following advantages and effect: the reasonable in design compactness, and flushing tissue and suction waste liquid are finished at a device, flushing is saved operating time freely, has avoided unnecessary postoperative infection, and easy to use and reliable, overall cost is low; Simultaneously, increased doctor's feel effect, made the doctor can not forget the valve location of flushing and suction, operation is used simpler, and feel is clear and definite.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing and by embodiment.

Referring to Fig. 1-Fig. 4, present embodiment mainly is made up of forward part 1 and the rear section 2 of mutual coupling.

The forward part 1 of present embodiment comprises probe 11, tee T 12, conduit 13, vacuum suction pipe joint 14, flushing valve 15 and suction valve 16, and rear section 2 comprises adapter 21, upper conduit 22, downcomer 23 and last syringe needle 24, following syringe needle 25; Probe 11 wherein, tee T 12, conduit 13, adapter 21, upper conduit 22, downcomer 23, last syringe needle 24, following syringe needle 25 are arranged in order.

In the present embodiment, the one side that adapter 21 and conduit 13 face mutually is provided with up and down two

positions

3,4 at least, conduit 13 is connected with one of them with up and down two

positions

3,4 couplings and when using, the another side of adapter 21 is connected with described upper conduit 22, downcomer 23 respectively, and this upper conduit 22, downcomer 23 match with conduit 13; Matching here refers to: during use, conduit 13 is arranged in up and down two

positions

3,4 one, and with upper conduit 22, downcomer 23 in one be connected.

The probe 11 of present embodiment, flushing valve 15 and suction valve 16 connect with three ends of tee T 12 respectively; Conduit 13 and vacuum suction pipe joint 14 are fixed on the tee T 12.

In the present embodiment, for increasing visual effect and feel effect, the face color of flush valve cover 15 is avy blue, and a boss 151 is arranged at top, and this boss 151 is connected with flush valve cover 15; The face color of suction valve gap 16 is red, and upper smooth does not have boss.
