Abstract
The utility model discloses an injector used in an ophthalmological operation, which comprises a syringe, a syringe needle and a pintle equipped with a piston. The core space of the syringe is divided into a suction chamber and a liquid injection chamber by the piston. The syringe needle comprises an inner tube and an outer tube. The core space of the inner tube is directly communicated with the liquid injection chamber. The chamber sandwiched between the inner tube and the outer tube is communicated with the suction chamber through a conduit. The front segments of both the inner tube and the outer tube are respectively provided with a curved part. Due to the adoption of the injector, the liquid injection and the liquid suction can be realized at the same time. The injector has the advantages of simple structure, low manufacturing cost and reasonable design.
Description
Technical field
This utility model is that a kind of ophthalmologic operation is used injection aspirator.
Background technology
At present, clinically to the treatment of cortical cataract, traditional method is with implantable artificial crystal behind the cataract extraction.The concrete employing is use injection aspirator, and on one side with the cortex sucking-off of cataract half jelly, one side is to the ophthalmic fluid injection; This is that this requires two people to operate simultaneously, and must work good because the ophthalmic anterior chamber pressure requirement of when operation is constant; It is synchronous just to reach suction and water filling, but this is a kind of perfect condition, because operation easier is big; Therefore, in operation process, can not remain the constant of intraocular pressure.
Summary of the invention
To the deficiency that prior art exists, this utility model provides the technical scheme of a kind of ophthalmologic operation with injection aspirator, adopts this technical scheme to make that the doctor is simple to operate, the patient is comfortable, and the one man operation can accomplish synchronous notes and inhale action, makes the intraocular pressure maintenance constant.
This utility model is realized through following technical measures: a kind of ophthalmologic operation is used injection aspirator; It comprises syringe, syringe needle, has the pintle of piston; Piston is divided into suction chamber and fluid injection chamber with the syringe inner chamber, pipe and outer tube in said syringe needle comprises, interior tube cavity and fluid injection chamber direct connection; Folder chamber in said between pipe and the outer tube is through conduit and suction chamber UNICOM, and the front end of said interior pipe and outer tube is provided with bending section.
The concrete improvement of this utility model also has, and the bending section of above-mentioned interior pipe and outer tube front end and the angle between the syringe are 30 degree.
During use; Earlier the fluid injection intracavity is filled normal saline; Syringe needle is inserted ophthalmic, promote piston forward and move, the saline of fluid injection intracavity gets into eyeball through interior tube cavity; Produce negative pressure this moment in suction chamber, water unnecessary in the surgical field of view enters in the suction chamber through folder chamber and conduit between interior pipe and the outer tube.
The beneficial effect of this utility model is: adopt this technical scheme to realize the purpose that aspirate on marginal not liquid, limit, it is simple in structure, low cost of manufacture, reasonable in design.This shows that this utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Fig. 1 is the structural representation of this utility model specific embodiment.
Among the figure, 1, syringe, 2, syringe needle, 3, piston, 4, pintle, 5, suction chamber, 6, the fluid injection chamber, 7, interior pipe, 8, outer tube, 9, the folder chamber, 10, conduit, 11, bending section.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme,, and combine it below through a specific embodiment
Accompanying drawing is set forth this programme.
Shown in accompanying drawing, a kind of ophthalmologic operation is used injection aspirator, and it comprises syringe 1, syringe needle 2, has the pintle 4 of piston 3; Piston 3 is divided into suction chamber 5 and fluid injection chamber 6 with syringe 1 inner chamber; Pipe 7 and outer tube 8 in its said syringe needle 2 comprises, interior pipe 7 inner chambers and fluid injection chamber 6 direct connections, the folder chamber 9 between said interior pipe 7 and the outer tube 8 is through conduit 10 and suction chamber 5 UNICOMs; The front end of pipe 7 and outer tube 8 is provided with bending section 11 in said, and the angle between bending section 11 and the syringe 1 is 30 degree.
This utility model can pass through existing techniques in realizing without the technical characterictic of describing, and repeats no more at this.Certainly; Above-mentioned explanation is not to be the restriction to this utility model; This utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of this utility model also should belong to the protection domain of this utility model.
Claims (2)
