Abstract
The utility model discloses an ophthalmic infusion-aspiration syringe. The ophthalmic infusion-aspiration syringe comprises a tail-end closed push tube, a piston, a push rod, an outer connecting tube, a first hollow needle head and a second hollow needle head, wherein the piston is arranged inside the closed push tube; the push rod penetrates through the tail end of the closed push tube to be connected with the piston; one end of the outer connecting tube is connected to the middle part of the closed push tube and communicated with the closed push tube; the first hollow needle head is arranged at the other end of the outer connecting tube; the second hollow needle head is arranged at the top end of the closed push tube; the top end of the first hollow needle head is of a spherical structure and is provided with a plurality of through holes; and the top end of the second hollow needle head is of a concave structure and is provided with a plurality of through holes. The ophthalmic infusion-aspiration syringe has the advantages of simple structure, lower cost and convenience for use at the same time, and can be used for washing eye tissues effectively and safely before an ophthalmic operation and during operation debridement.
Description
Technical field
This utility model relates to a kind of medical apparatus, especially a kind of ophthalmology injection aspirator.
Background technology
The clinical ophthalmology operation will be washed eye usually, removes in the operation even more important for cataract.In general, irrigation and disinfection to be carried out before the art, in art, more wound surface will be in time cleared up.
Common mode adopts the injection aspirator of thin sebific duct or similar needle tubing to carry out eye and cleans.Thin sebific duct flushing is very inconvenient, can't in time clear up medicinal liquid; The injection aspirator of similar needle tubing often because syringe needle is too sharp-pointed, has careless manipulation slightly, will injure eyeball tissue.
Therefore, need a kind of new ophthalmology injection aspirator to solve before the ophthalmologic operation and the problem of safe and effective cleaning part tissue of eye in the operation debridement.
Summary of the invention
In view of this, this utility model is devoted to better to solve the preceding problem that reaches safe and effective cleaning part tissue of eye in the operation debridement of ophthalmologic operation, has proposed a kind of ophthalmology injection aspirator.
The technical scheme that this utility model adopts is:
A kind of ophthalmology injection aspirator comprises the closed ejector sleeve of tail end, be arranged on the inner piston of closed ejector sleeve, penetrate closed ejector sleeve tail end and the push rod that is connected with piston, an end is connected closed ejector sleeve middle part and be connected draw connection tube outward, be arranged on first hollow pinhead that draws the connection tube other end outward, be arranged on vertical second hollow pinhead of closed ejector sleeve; Wherein, the said first hollow pinhead top is spherical structure and is provided with a plurality of open-works; The top of second hollow pinhead is concave structure and is provided with a plurality of open-works.
The quantity that the top spherical structure of above-mentioned first hollow pinhead is provided with open-work is 5.
The above-mentioned outer connection tube that draws is fixedly connected with closed ejector sleeve employing with the concordant part of closed ejector sleeve.
The top of above-mentioned first hollow pinhead and second hollow pinhead is long together.
The beneficial effect of this utility model is:
This utility model is simple in structure, but efficiently solves the preceding problem that reaches safe and effective cleaning part tissue of eye in the operation debridement of ophthalmologic operation, and simultaneously, cost is lower, and is easy to use.
