Abstract
The utility model provides a synchronous equivalent infusion-aspiration syringe for ophthalmologic operation, and relates to the technical field of medical appliances. The synchronous equivalent infusion-aspiration syringe comprises a needle cylinder, pistons, catheters, bearings, screw rods, sleeves, gears and a crank, and is characterized in that the interior of the needle cylinder is divided into two cavities which have the same size and respectively have a square cross section; the cavities are respectively and internally provided with the corresponding pistons; the front end of each cavity is provided with the catheter communicated with the cavity; the inner wall of the rear end of each cavity is connected with the bearing; the screw rods are fixedly sheathed in the bearing, the screw rods arranged in the cavities are respectively connected with the sleeves fixedly arranged at the back surfaces of the pistons by threads; the outer ends of the two screw rods are respectively connected with the two gears which are meshed with each other; and the center of one gear is fixedly connected with the crank. The synchronous equivalent infusion-aspiration syringe is simple in structure and simple and convenient to operate, can be used for completing the synchronous infusion-aspiration action by the operation of a single person, and enabling the amount of liquid injected into the anterior chamber and the amount of liquid discharged from the anterior chamber to be equal, thus maintaining the anterior chamber to be stable and reducing the complication.
Description
Technical field: this utility model relates to the medical instruments technical field, 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 implant surgery, make cataractopiesis become the cataractous means for the treatment of, 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, namely constant for maintenance anterior chamber pressure when drawing anterior chamber's residual liquid, must be synchronously toward interior water filling, this just requires two people to operate simultaneously, one is carried out the drain suction, another past interior water filling, and must work good.So not only troublesome poeration is wasted time and energy, nor easily synchronously, can not remain the constant of intraocular pressure.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of one man operation can finish synchronous notes and inhales action, can make intraocular pressure remain constant ophthalmologic operation with synchronous equivalent injection aspirator.
The purpose of this utility model is achieved in that this ophthalmologic operation comprises syringe, piston, conduit, bearing, screw rod, sleeve pipe, gear, crank with synchronous equivalent injection aspirator, syringe inside is divided into two identical cross sections of size and is respectively square cavity, cavity inside is respectively equipped with the piston that adapts with it, and each cavity front end is respectively equipped with the conduit that communicates with it; Each cavity rear end inwall is connected with bearing respectively, be set with fixing screw rod in the bearing inner sleeve, screw rod in the cavity is connected with the casing threads that is fixed on the piston back side respectively, two screw rod outer ends link to each other with two pitch wheels respectively, one of them gear centre place fixedly connected crank.
Rotate crank and can make a piston reach, a piston retreats, and the piston that moves forward is released the infusion liquid in its cavity, and Yi Dong piston sucks the liquid aliquot in the anterior chamber in its cavity simultaneously backward.
Advantage of the present utility model: simple in structure, easy and simple to handle, the one man operation can finish synchronous notes and inhale action, and the amount of liquid that pours in the anterior chamber and discharge is equated, stablizes thereby keep the anterior chamber, reduces complication and takes place.
Description of drawings: Fig. 1 is structure cutaway view of the present utility model.
The specific embodiment: describe in further detail below in conjunction with this utility model of Fig. 1: this ophthalmologic operation comprises syringe 1, piston 2, conduit 3, bearing 4, screw rod 5, sleeve pipe 6, gear 7, crank 8 with synchronous equivalent injection aspirator, syringe 1 inside is divided into two identical cross sections of size and is respectively square cavity, cavity inside is respectively equipped with the piston 2 that adapts with it, and each cavity front end is respectively equipped with the conduit 3 that communicates with it; Each cavity rear end inwall is connected with bearing 4 respectively, be set with fixing screw rod 5 in the bearing 4 in the cover, screw rod 5 in the cavity is threaded with the sleeve pipe 6 that is fixed on piston 2 back sides respectively, two screw rod 5 outer ends link to each other with two pitch wheels 7 respectively, one of them gear 7 center fixedly connected crank 8.
