Abstract
The utility model relates to an infusion and suction device for a cataract surgery. The technical scheme is that the infusion and suction device includes an outer sleeve, an inner sleeve, a piston, a push-pull rod, a handle, a negative pressure tube, a negative pressure bottle, a control valve, a first connecting tube, a second connecting tube, a dual-cavity infusion and suction needle and a sleeve cover, wherein the inner sleeve is fixed inside the outer sleeve; the piston and the push-pull rod are arranged inside the inner sleeve; the first connecting tube and the second connecting tube are arranged at one end of the outer sleeve; the sleeve cover is arranged at the other end of the outer sleeve; the dual-cavity infusion and suction needle is connected with the outer parts of the first connecting tube and the second connecting tube; the first connecting tube is connected with the outer sleeve; the second connecting tube is connected with the inner sleeve; the negative pressure tube is connected with the outer part of the first connecting tube; and the negative pressure tube is connected with the negative pressure bottle through the control valve. The infusion and suction device has the benefits that the structure is simple, the use is convenient, synchronous and equivalent infusion and suction can be completed by one man, infusion liquid and suction liquid are equal in volume, pressure of an intraocular anterior chamber is kept constant, so that the surgery is facilitated, and the achievement ratio of surgery is improved.
Description
Technical field
This utility model relates to a kind of armarium, and particularly a kind of cataract operation is inhaled device with annotating.
Background technology
At present, in the clinical ophthalmology operation, success due to artificial intraocular lenses's implant surgery, make cataractopiesis become the cataractous means for the treatment of, but the wound surface of this operation cleaning more complicated, rinsing before the room in art is an important ring, traditional developing technique is to rinse with the single needle pipe, but not thorough, complication is many.The drainage device of using in general art does not reach again requirement, this is because the ophthalmic anterior chamber pressure requirement of when operation is constant, namely constant for maintenance anterior chamber pressure when drawing anterior chamber's residual liquid, must be synchronous toward interior water filling, this just requires two people to operate simultaneously, one is carried out the drain suction, another past interior water filling, and must work good.Be troublesome poeration like this, waste time and energy, be not easy again synchronously can not remain the constant of intraocular pressure.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of cataract operation to inhale device with annotating, and is simple in structure, easy to use.
its technical scheme is: comprise outer sleeve, inner sleeve, piston, push-pull bar, the hands handle, negative tube, negative pressure bottle, control valve, first takes over, second takes over, two-chamber is annotated the suction spindle head, socket cover, inner sleeve is fixed on outer sleeve inside, inner sleeve inside is provided with piston and push-pull bar, one end of outer sleeve is provided with first and takes over and the second adapter, the other end of outer sleeve is provided with socket cover, first takes over and is connected the outside connection two-chamber notes suction spindle head of taking over, the first adapter is connected with outer sleeve, the second sleeve pipe is connected with inner sleeve, first takes over the outside negative tube that connects, described negative tube connects negative pressure bottle by control valve.
The beneficial effects of the utility model are: simple in structure, easy to use, the one man operation can complete synchronous identical size injection and inhale action, and injection and the aspirated liquid scale of construction are equated, thereby makes ophthalmic anterior chamber pressure keep constant, is conducive to operation and carries out, and has improved success rate of operation.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: outer sleeve 1, inner sleeve 2, piston 3, push-pull bar 4, handle 5, negative tube 6, negative pressure bottle 7, control valve 8, first are taken over the 9, second adapter 10, two-chamber is annotated suction spindle head 11, socket cover 12.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
this utility model comprises outer sleeve 1, inner sleeve 2, piston 3, push-pull bar 4, handle 5, negative tube 6, negative pressure bottle 7, control valve 8, first takes over 9, second takes over 10, two-chamber is annotated suction spindle head 11, socket cover 12, inner sleeve 2 is fixed on outer sleeve 1 inside, inner sleeve 2 inside are provided with piston 3 and push-pull bar, one end of outer sleeve 1 is provided with first and takes over the 9 and second adapter 10, the other end of outer sleeve 1 is provided with socket cover 12, first takes over 9 takes over 10 outside connection two-chamber notes suction spindle head 11 with being connected, first takes over 9 is connected with outer sleeve 1, the second sleeve pipe 10 is connected with inner sleeve 2, first takes over the 9 outside negative tubes 6 that connect, described negative tube 6 connects negative pressure bottle 7 by control valve 8.
This utility model is simple in structure, and is easy to use, and the one man operation can complete synchronous identical size injection and inhale action, and injection and the aspirated liquid scale of construction are equated, thereby makes ophthalmic anterior chamber pressure keep constant, is conducive to operation and carries out, and improved success rate of operation.
