Abstract
An injector for ophthalmic operation belongs to the technical field of medical apparatuses, comprises a syringe (1), a piston (2), a pintle (3) and a two-chamber injecting needle (4), and is characterized in that the inner wall on the rear end of the syringe (1) is provided with a seal ring (5), the cylindrical pintle (3) on the upper side of the piston (2) in the syringe (1) is threaded through the seal ring (5), and is connected with the seal ring (5) in sliding and sealing mode, the outer wall of the syringe (1) is axially provided with a guide pipe (6) which is communicated with a rear cavity of the syringe (1), and two connectors on the rear end of the two-chamber injecting needle (4) are respectively sleeved on the front end of the guide pipe (6) and a nipple on the front end of the syringe (1). The injector for ophthalmic operation has simple structure and convenient use, and synchronous and equivalent injecting action can be finished by one person, which enables injected liquid to be equal to pumped liquid, thereby anterior chamber pressure in an eye keeps constant, which is beneficial for operations.
Description
Technical field
This utility model belongs to technical field of medical instruments, the ophthalmologic operation injection aspirator that specifically a kind of ophthalmologic operation cleaning wound surface is used.
Background technology
At present, in the clinical ophthalmology operation, because the success of artificial intraocular lenses's implant surgery, make cataractopiesis become the cataractous means of treatment, but the wound surface of this operation cleaning more complicated, washing before the room in the art is an important ring, traditional developing technique is to wash with the single needle pipe, but not thorough, complication is many.The drainage device of using in the general art does not reach requirement again, 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 to overcome above-mentioned deficiency, provides a kind of simple in structure, easy to use, and the one man operation can finish synchronous notes and inhale action, makes intraocular pressure keep constant ophthalmologic operation injection aspirator.
The purpose of this utility model is achieved in that this ophthalmologic operation annotates the suction spindle head with injection aspirator by syringe, piston, pintle, two-chamber and form, the back end of syringe inwall is provided with sealing ring, and the cylindrical pintle above the syringe inner carrier passes sealing ring and is connected with the sealing ring slipper seal; The syringe outer wall is axially arranged with the conduit that communicates with the back end of syringe inner chamber, and two joints that two-chamber is annotated suction spindle head rear end are set on the nipple of catheter proximal end and syringe front end.
During use, promoting pintle forward can release by the pin chamber that piston is annotated the liquid in the syringe in the suction spindle head by two-chamber, form negative pressure in the syringe of piston back simultaneously, can be by in the syringe that is drawn into the piston back of conduit with the synchronous equivalent of residual liquid in the anterior chamber.
Advantage of the present utility model: simple in structure, easy to use, the one man operation can finish synchronous equivalent and annotate the suction action, and the injection and the aspirated liquid scale of construction are equated, thereby makes ophthalmic anterior chamber pressure keep constant, helps performing the operation and carries out.
Description of drawings
Accompanying drawing is a structure cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this ophthalmologic operation is annotated suction spindle head 4 with injection aspirator by syringe 1, piston 2, pintle 3, two-chamber and is formed, syringe 1 rear end inwall is provided with sealing ring 5, and the cylindrical pintle 3 above syringe 1 inner carrier 2 passes sealing ring 5 and is connected with sealing ring 5 slipper seals; Syringe 1 outer wall is axially arranged with the conduit 6 that communicates with syringe 1 rear end inner chamber, and two joints that two-chamber is annotated suction spindle head 4 rear ends are set on the nipple of conduit 6 front ends and syringe 1 front end.
Claims (1)
1, a kind of ophthalmologic operation injection aspirator, annotating suction spindle head (4) by syringe (1), piston (2), pintle (3), two-chamber forms, it is characterized in that syringe (1) rear end inwall is provided with sealing ring (5), the cylindrical pintle (3) above syringe (1) inner carrier (2) passes sealing ring (5) and is connected with sealing ring (5) slipper seal; Syringe (1) outer wall is axially arranged with the conduit (6) that communicates with syringe (1) rear end inner chamber, and two joints that two-chamber is annotated suction spindle head (4) rear end are set on the nipple of conduit (6) front end and syringe (1) front end.
