Abstract
A synchronous equivalent infusion-aspiration syringe for ophthalmologic operation belongs to the technical field of medical appliances, which is composed of a tube cylinder, an infusion needle cylinder, an aspiration needle cylinder, pistons, a piston rod and a double-tube infusion-aspiration needle head. The synchronous equivalent infusion-aspiration syringes is characterized in that the tube cylinder is axially equipped with two rectangular through holes which are mutually symmetrical, two ends of the tube cylinder are respectively in threaded connection with the infusion needle cylinder and the aspiration needle cylinder, the pistons in the infusion needle cylinder and the aspiration needle cylinder are respectively connected through the piston rod, the lower end of a supporting rod with a finger ring respectively penetrates through the two rectangular through holes on the tube cylinder to connect with the middle portion of the piston rod, two hoses at the rear end of the double-tube infusion-aspiration needle head are respectively connected with an infusion connector and an aspiration connector on lateral walls of the front ends of the infusion needle cylinder and the aspiration needle cylinder. The utility model has the advantages of simple structure, convenient use, can complete synchronous equivalent infusion-aspiration actions by one person, enables infusion and aspiration to be completed synchronously and equivalently, enables pressure in eyes to keep constant, and reduces complication.
Description
Technical field
This utility model belongs to technical field of medical instruments, and specifically a kind of ophthalmologic operation is with synchronous equivalent injection aspirator.
Background technology
At present, in the clinical ophthalmology operation, because the success of artificial intraocular lenses's implantation surgery makes cataractopiesis become the cataractous main means of treatment, but the wound surface of this operation cleaning more complicated, anterior chamber's cleaning is an important ring in the art.Traditional method is that but not thorough, complication is many with the flushing of single needle pipe.The drainage device of using in the general operation does not reach requirement, this is because the ophthalmic anterior chamber pressure requirement of when operation is constant, and is promptly when drawing anterior chamber's residual liquid, constant for guaranteeing anterior chamber's pressure, must be synchronously toward interior water filling, this just requires two people to operate simultaneously, and one is carried out the drain suction, and another is toward interior water filling, and must work good, so promptly trouble is not easy again synchronously, is difficult to keep intraocular pressure constant.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of one man operation just can finish synchronous equivalent and annotates and inhale action, makes intraocular pressure keep constant ophthalmologic operation with synchronous equivalent injection aspirator.
The purpose of this utility model be achieved in that this ophthalmologic operation with synchronous equivalent injection aspirator by socket, the perfusion syringe, the suction syringe, piston, piston rod, two-tube notes suction spindle head constitutes, socket is axially arranged with two symmetrical rectangular through holes, two ends be threaded respectively the perfusion syringe and the suction syringe, the perfusion syringe links to each other by piston rod respectively with the interior piston of suction syringe, two rectangular through holes that the support bar lower end that has a finger ring is passed respectively above the socket are connected the piston rod middle part, and two flexible pipes of two-tube notes suction spindle head rear end are connected on perfusion syringe and the perfusion joint and suction joint above the suction syringe front end side wall.
Advantage of the present utility model: simple in structure, easy to use, the one man operation just can finish synchronous equivalent and annotate the suction action, makes and pours into and aspirate synchronous equivalent and finish, and makes intraocular pressure keep constant, reduces the complication generation.
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 with synchronous equivalent injection aspirator by socket 1, perfusion syringe 2, suction syringe 3, piston 4, piston rod 5, two-tube notes suction spindle head 6 constitutes, socket 1 is axially arranged with two symmetrical rectangular through holes 7, two ends be threaded respectively perfusion syringe 2 and suction syringe 3, perfusion syringe 2 links to each other by piston rod 5 respectively with suction syringe 3 interior pistons 4, two rectangular through holes 7 that support bar 9 lower ends that have a finger ring 8 are passed respectively above the socket 1 are connected piston rod 5 middle parts, and two flexible pipes of two-tube notes suction spindle head 6 rear ends are connected on perfusion syringe 2 and the perfusion joint 10 and suction joint 11 above suction syringe 3 front end side wall.
