Abstract
The utility model discloses a modified surgical irrigating-aspirating device which comprises an irrigating-aspirating tube, a needle, a piston, a pusher, and a suction tube, wherein the irrigating-aspirating tube is cylindrical and is divided inside by the piston into an aspiration chamber and an irrigation chamber; the needle has two chambers, in which one is a syringe communicated with the irrigation chamber and the other one is a suction needle communicated with the aspiration chamber by the suction tube; and the pusher is fixed on the piston. The irrigating-aspirating device integrates the irrigation and aspiration functions, and forms a dynamic constant-pressure circulation system by the aspiration chamber and irrigation chamber with the anterior chamber. When the pusher is pushed, the water inside the irrigation chamber flows through the syringe into the anterior chamber and simultaneously the aspiration chamber has a negative pressure, therefore, the residual liquid in the anterior chamber is pumped to the aspiration chamber after flowing through the aspiration needle and suction tube. The utility model realizes simultaneous operation of aspiration and irrigation by only one operator.
Description
Technical field
This is practical to relate to the particularly injection aspirator tool used of ophthalmologic operation cleaning wound surface of a kind of clinical operation, belongs to medicine and hygiene fields.
Background technology
At present, in the clinical ophthalmology operation, because the success of artificial intraocular lenses's implant surgery, make cataractopiesis become the cataractous main means of treatment, but the wound surface of this operation cleaning more complicated, anterior chamber's flushing is an important ring in the art, it is to wash with the single needle pipe for traditional flushing worker, but not thorough, complication is many.The drainage device of using in the general operation does not reach requirement, this is because the ophthalmic anterior chamber pressure requirement of when operation is constant, promptly when drawing anterior chamber's residual liquid, for keeping anterior chamber's pressure constant, must be synchronously toward interior water filling, this just requires two people to operate simultaneously, and one is carried out the drain suction, another past interior water filling, and must work good.Seem like this and i.e. trouble be not easy to remain the constant of intraocular pressure synchronously again.
Summary of the invention
The purpose of this utility model is the problem that exists at cleaning wound surface in the above cataractopiesis, a kind of improved injection aspirator is provided, it only needs hand operated of people of patient to finish and annotates the suction action accurately synchronously, makes intraocular pressure keep constant, and simple in structure, easy to use.
The purpose of this utility model is to realize like this, this improved operation injection aspirator comprises annotates suction pipe, syringe needle, piston, push rod, suction pipe, described notes suction pipe is a cylindrical shape, be divided into suction chamber and injection room by the pipe inner carrier, described syringe needle is a two-chamber, and promptly a chamber is entry needle and communicates with the injection room, and a chamber is an aspiration needle, described aspiration needle communicates with suction chamber by suction pipe, and described push rod is connected on the piston.
Owing to adopt said structure, this injection aspirator is combined as a whole owing to injecting, aspirating, in injection room, suction chamber, anterior chamber, form a dynamic constant voltage blood circulation, when promoting the piston motion by push rod, water in the injection room enters in the anterior chamber by entry needle, form negative pressure at suction chamber simultaneously,, reach one man operation synchronous purpose fully because the residual liquid in the effect anterior chamber of negative pressure is inhaled into suction chamber by aspiration needle, suction pipe.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
Fig. 1 is a cutaway view of the present utility model
Fig. 2 is the cutaway view of Fig. 1 at the A-A place
Among the figure: 1, annotate suction pipe 2, suction chamber 3, injection room 4, entry needle 5, aspiration needle 6, suction pipe 7, piston 8, push rod
The specific embodiment
As shown in Figure 1 and Figure 2, this improved operation injection aspirator comprises annotates suction pipe 1, syringe needle, piston 7, push rod 8, suction pipe 6, annotating suction pipe 1 is cylindrical shape, be divided into suction chamber 2 and injection room 3 by pipe inner carrier 7, syringe needle is a two-chamber, and promptly a chamber is entry needle 4 and communicates with injection room 3, and a chamber is an aspiration needle 5, aspiration needle 5 communicates with suction chamber 2 by suction pipe 6, and push rod 8 is connected on the piston 7.This injection aspirator is combined as a whole owing to injecting, aspirating, in injection room 3, suction chamber 2, anterior chamber, form a dynamic constant voltage blood circulation, when promoting piston 7 motions by push rod 8, the water that the injection room is 3 li enters in the anterior chamber by entry needle 4, in suction chamber 2, form negative pressure simultaneously, because the residual liquid in the effect anterior chamber of negative pressure is inhaled into suction chamber 2 by aspiration needle 5, suction pipe 6, reach one man operation synchronous purpose fully.
