CN201179147Y - Cortex aspirator for cataract surgery - Google Patents

Abstract

The utility model relates to a cortex aspirator used for cataract operation, which consists of a needle body 1 and a needle tail injector connector 2, wherein, the needle body 1 is hollow so as to form an aspirating pipeline 3 that is communicated with the needle tail injector connector 2; the front end 4 of the needle body 1is of an semicircular blunt nose, and an opening 5 of the aspirating pipeline is arranged at one side of the front end 4 of the needle body. The possibly accidental damage that can be caused by a needlepoint of the common injector to the eye tissue can be avoided. The needle body 1 has three forms of right angle, bending angle and arc so as to facilitate the operation. The cortex aspirator used for cataract operation has the advantages that the structure is simple, the use is convenient and safe, basically no damage can be caused to the eyes of patient and the use as a disposable medical apparatus is available.

Description

A kind of cataract operation cortex aspirator

Technical field

This utility model relates to medical instruments field, is specifically related to a kind of cortex aspirator that uses in the ophthalmology cataract operation.

Background technology

Cataract is domestic and international at present primarily one of diseases causing blindness, and blind rate is 10～20%.The cataract main cause is that the smooth and crystalline lens metabolism protein of eye microcirculation can not decompose absorption fully, causes in the eyes crystalline lens to take place muddyly to become opaquely by transparent, and obstruction light enters ophthalmic, thereby has influenced vision.No matter be senile cataract, congenital cataract, aftercataract or traumatic cataract, operative treatment is to treat the most effective means of cataract at present, the modern day cataract ECCE is meant the microsurgery under the axis light illumination, basic modus operandi is a capsule middle body before puncturing and tearing off, crystal nuclear is given birth to, annotate exhaust cortex in the peripheral capsule bag of suction spindle head synchronously with cataract, keep the preceding capsule of complete posterior lens capsule and periphery.As can be seen, the cortex sucking-off is the important step of cataract operation, the cataract operation of present domestic use is exactly the ordinary syringe syringe needle with the cortex aspirator, there is certain problem during use, ocular tissue's damage may be caused in the tip that the syringe needle front end is sharp keen, the generation problem not only influences the carrying out of operation, in case may cause the bigger treatment of patient to incur loss through delay.In view of above reason, the cortex aspirator that is used for cataract operation haves much room for improvement, and it is little to press for a kind of damage, causes tissue defect, medical apparatus and instruments simple to operate, that be used for the sucking-off of cataract operation cortex hardly.

The utility model content

This utility model provides a kind of simple in structure for overcoming above-mentioned the deficiencies in the prior art, causes tissue defect hardly, and operation time is short, cataract operation easy to use cortex aspirator.

The technical solution of the utility model is as follows:

A kind of cataract operation comprises the needle body and backshank syringe adapter with the cortex aspirator, the needle body and backshank syringe adapter are all made with medical metal, similar with the syringe needle profile, the needle body one end is connected with the backshank syringe adapter, the centre is a hollow, it is the suction extraction channel runs that is communicated with the backshank syringe adapter, different with general syringe needle is cataract operation is not a sharp-pointed tip but half garden shape is blunt nosed with cortex aspirator needle body front end, the suction extraction channel runs opening is arranged on a side of needle body front end, the accidental injury that can avoid the sharp-pointed tip of general syringe needle that ocular tissue is caused like this.

In addition, cataract operation can adopt versions such as right angle, bent angle and arc with the cortex aspirator needle body, so that the operation that undergos surgery.

This utility model is simple in structure, and safety easy to use to the basic not damaged of patient's eye, can be used as disposable medical article and uses.

Description of drawings

Fig. 1 is this utility model structural representation.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is further specified.

As shown in Figure 1, this cataract operation comprises the needle body 1 and backshank syringe adapter 2 with the cortex aspirator, the needle body 1 rear end is connected with backshank syringe adapter 2, hollow forms the suction extraction channel runs 3 that is communicated with backshank syringe adapter 2 in the middle of the needle body 1, needle body front end 4 is that half garden shape is blunt nosed, suction extraction channel runs opening 5 is opened the side at needle body front end 4, and the needle body 1 can adopt forms such as right angle, bent angle and arc.

Using method: when in the cataract patient art, needing by predetermined way cortex sucking-off successively, the backshank syringe adapter 2 of syringe and cortex aspirator is connected firmly, then the cortex aspirator needle body 1 is stretched into interior otch, the piston of pulling syringe, cause negative pressure, make cortex enter suction extraction channel runs 3 by the suction extraction channel runs opening 5 of needle body front end 4, arrive in the syringe at last, move or rotate cataract operation cortex aspirator gently, control needle body position, cortex is drawn totally, extracted out the cortex aspirator then and get final product.

Claims (2)

1, a kind of cataract operation cortex aspirator, it is made up of the needle body (1) and backshank syringe adapter (2), and the needle body (1) hollow forms the suction extraction channel runs (3) that is communicated with backshank syringe adapter (2); It is characterized in that: the front end (4) of the described needle body (1) is that half garden shape is blunt nosed, and suction extraction channel runs opening (5) is arranged on a side of needle body front end (4).

2, cataract operation according to claim 1 cortex aspirator is characterized in that: the described needle body (1) has right angle, bent angle and three kinds of forms of arc.
