A kind of operation flushing aspiratorTechnical field
The present invention relates to a kind of suction pump, particularly a kind of operation flushing aspirator, it is mainly applicable to, in abdominal cavity microtrauma operation, belong to medical apparatus and instruments.
Background technology
Due in operation, operative site is ceaselessly rinsed to tissue and ceaselessly aspirates waste liquid is simultaneous, this just needs the apparatus of an apparatus rinsed and a suction, two kinds of apparatuses ceaselessly change use in use, in operation, cooperate suitable trouble like this, waste operating time again simultaneously; Prior, flushing liquor likely flows to No operation position owing to can not be sucked at once, causes infection to tissue, and more troublesome is in microtrauma operation, may not stop like this to change hardly to use, and brings very large inconvenience to operation.
The flush valve cover of clinical flushing aspirator is all the same with aspirating valve gap profile with face color, so just there is no visual effect and feel effect, doctor is allowed to be difficult to understand fast the use of flushing aspirator, time has been grown doctor and may have forgotten the valve location rinsing and aspirate, and brings inconvenience to operation.
China Patent No. 2012101810492 discloses the patent of invention that a kind of name is called " operation suction apparatus of band illumination cleaning function ", although it has suction function, but it can only rinse optical fiber head, and can not carry out I & A to operative site, therefore it does not still overcome above-mentioned defect of the prior art simultaneously.
China Patent No. 2011100865671 discloses the patent of invention that a kind of name is called " built-in aspirator for laparoscope operation ", rinse and suction waste liquid although it can carry out tissue to operative site simultaneously, but it is that suction pump is placed on intraperitoneal all the time when performing the operation, to reduce the drawback changed apparatus and bring; So inevitably there is following shortcoming in it: during owing to using, doctor must catch with pliers and hold sucking head absorption oozing of blood and sepage, so doctor is difficult to accomplish to get express developed, aspirate fast, this just likely causes oozing of blood and sepage to infect No operation position because not aspirating.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, and provide a kind of structural design more reasonable, the operation flushing aspirator of tissue flushing and suction waste liquid can be carried out simultaneously to operative site.
The present invention's adopted technical scheme that solves the problem is: this operation flushing aspirator is characterized in that: it comprises forward part and the rear section of coupling mutually, forward part comprises probe, tee T, conduit, negative pressure suction tube joint, flushing valve and suction valve, and 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; Described adapter and the adjacent one side of conduit are at least provided with upper and lower two positions, and conduit is with these upper and lower two location matches and be connected with one of them, the another side of adapter respectively with described upper and lower tubes connection, 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 negative pressure suction tube joint are fixed on tee T.Make the present invention when needs rinse thus, open flushing valve and carry out tissue flushing, now aspirate valve and be in about state; When needs suction waste liquid, open suction valve and carry out waste liquid suction, now flushing valve is in closed condition, ensure that to rinse organize and can aspirate waste liquid.
Flushing valve of the present invention or suction valve in one on be provided with boss, this boss is connected with valve.To increase feel effect, allow doctor understand the use of flushing aspirator fast, and make doctor can not forget the valve location rinsing and aspirate, bring convenience to operation.
The present invention is respectively arranged with upper and lower vessel clamp on described upper and lower conduit.To control flushing speed and pumping velocity.
The present invention compared with prior art, has the following advantages and effect: reasonable in design is compact, rinses tissue and aspirate waste liquid to complete on a device, rinse freely, save operating time, avoid unnecessary postoperative infection, and easy to use and reliable, overall cost is low; Meanwhile, add the feel effect of doctor, make doctor can not forget the valve location rinsing and aspirate, operation uses simpler, and feel is clear and definite.

Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the invention will be further described.
See Fig. 1-Fig. 4, the present embodiment forms primarily of the forward part 1 of mutually mating and rear section 2.
The forward part 1 of the present embodiment comprises probe 11, tee T 12, conduit 13, negative pressure suction tube joint 14, flushing valve 15 and suction valve 16, and rear section 2 comprises adapter 21, upper conduit 22, downcomer 23 and upper syringe needle 24, lower syringe needle 25; Probe 11 wherein, tee T 12, conduit 13, adapter 21, upper conduit 22, downcomer 23, upper syringe needle 24, lower syringe needle 25 are arranged in order.
In the present embodiment, adapter 21 one side adjacent with conduit 13 is at least provided with upper and lower two positions 3,4, conduit 13 is connected with one of them when mating with these upper and lower two positions 3,4 and use, 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, and conduit 13 is arranged in one of upper and lower two positions 3,4, and is connected with in upper conduit 22, downcomer 23.
The probe 11 of the present embodiment, flushing valve 15 and suction valve 16 connect with three ends of tee T 12 respectively; Conduit 13 and negative pressure suction tube joint 14 are fixed on 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 is without boss.
For ensureing to control flushing speed and pumping velocity, upper conduit 22, downcomer 23 are respectively arranged with upper conduit folder 221, downcomer folder 231.
In the present embodiment, probe 11, tee T 12, conduit 13, adapter 21, upper and lower conduit 22,23 and upper and lower syringe needle 24,25 and negative pressure suction tube joint 14 are hollow structure.
When needs rinse, open flushing valve 15 and carry out tissue flushing, now aspirate valve 16 and be in about state; When needs suction waste liquid, open suction valve 16 and carry out waste liquid suction, now flushing valve 15 is in closed condition, ensure that to rinse organize and can aspirate waste liquid.
Concrete connection and use as follows: probe 11 and tee T 12 sealed attachment, flushing valve 15 and suction valve 16 assemble with tee T 12, and can move up and down according to operation needs in tee T 12, control to rinse and aspirate.
When one end of conduit 13 connects with tee T 12, the other end connects when connecting with upper conduit 22 and upper syringe needle 24 again with adapter 21, ensures that flushing liquor can be controlled by flushing valve 15, is connected to probe 11 from upper conduit 22, thus ensure pre-washing function.
When conduit 13 one end connects with tee T 12, when the other end is connected with negative pressure suction tube joint 14 by downcomer 23 and lower syringe needle 25, ensure that waste liquid can be controlled by suction valve 16, be connected to negative pressure suction tube joint 14 from probe 11, thus ensure pumping function.
Allly conceive according to the present invention the equivalence or simple change that described structure, feature and principle do, be included in the protection domain of patent of the present invention.
