Abstract
The utility model relates to an ophthalmic operation-used synchronous and isometrical injection and absorbing device, which belongs to the technical field of a medical appliance device, and comprises a micron-motor, a speed change box, a box body, a gear, syringes and a double-tube cannula I/A, and is characterized in that the micron-motor is connected with the gear in the box body through the output end of the transmission shaft of the speed change box; control buttons which can ensure the micron-motor to be rotated in the positive direction and reverse direction and to be stopped are respectively arranged on the outer wall on the upper panel of the box body; the two syringes with identical sizes are fixed on the right panel; a gear rack which is meshed with the gear is connected with the upper surface of a piston in each syringe, and a limiting guide rail is arranged on the other side of each gear rack; a handle is sleeved on the outer wall at the rear end of the double-tube cannula I/A, and hoses on the upper surfaces at the rear end of the two tube cavities of the double-tube cannula I/A are respectively connected with nipples at the front ends of the two syringes. The ophthalmic operation-used synchronous and isometrical injection and absorbing device has the advantages that the volume of the liquid injected into and discharged from the anterior chamber can be equal, the stable anterior chamber can be ensured, and the number of the occurrence of the complication is reduced.
Description
Technical field
This utility model belongs to technical field of medical instruments, and specifically a kind of ophthalmologic operation is annotated with synchronous equivalent and inhaled device.
Background technology
At present, in clinical cataract operation or anterior chamber's flush operation, usually use injection aspirator, injection aspirator relies on the height of regulating the infusion liquid transfusion bottle to regulate the amount that infusion liquid enters ophthalmic, come the negative pressure of suction Controlled needle tubing to regulate aspiration by the doctor with hands, both are asynchronous, are difficult to accomplish the synchronous equivalent of groundwater increment and aspiration, cause that easily the anterior chamber fluctuates.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of making to pour into and aspirate synchronous equivalent and finish, and guarantees that the anterior chamber is stable, reduces the ophthalmologic operation of complication generation and inhales device with synchronous equivalent notes.
The purpose of this utility model is achieved in that this ophthalmologic operation is annotated with synchronous equivalent and inhales device and be made up of micromachine, change speed gear box, casing, gear, syringe, two-tube notes suction spindle head, micromachine links to each other with the intravital gear of case by the jack shaft outfan, be respectively equipped with the control knob that can make micromachine just change, reverse and stop operating at casing upper face outer wall, fixing two syringes that size is identical on the right panel face, all be connected with the tooth bar that is meshed with gear above the piston in each syringe respectively, the tooth bar opposite side all is respectively equipped with spacing track; Two-tube notes suction spindle head rear end outer wall is with handle, and the flexible pipe above two tube chamber rear ends of two-tube notes suction spindle head is connected on the nipple of two syringe front ends.
Advantage of the present utility model: starter motor can make gear rotate, can make a piston reach in the syringe with the tooth bar of gears engaged, piston in another syringe retreats, the piston that moves forward is released the infusion liquid in the syringe, the piston of Yi Donging sucks the liquid aliquot in the anterior chamber in another syringe simultaneously backward, the amount of liquid that pours in the anterior chamber and discharge is equated, stablize, reduce complication and take place thereby keep the anterior chamber.
Description of drawings
Accompanying drawing is a structural representation 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 with synchronous equivalent and is inhaled device by micromachine 1, change speed gear box 2, casing 3, gear 4, syringe 5, two-tube notes suction spindle head 6 is formed, micromachine 1 links to each other with gear 4 in the casing 3 by change speed gear box 2 power transmission shaft outfans, be respectively equipped with at casing 3 upper face outer walls micromachine 1 is just being changeed, counter-rotating and the control knob that stops operating, fixing two syringes 5 that size is identical on the right panel face, all be connected with the tooth bar 7 that is meshed with gear 4 respectively above the piston in each syringe 5, tooth bar 7 opposite sides all are respectively equipped with spacing track 8; Two-tube notes suction spindle head 6 rear end outer walls are with handle 9, and the flexible pipe 10 above 6 two tube chamber rear ends of two-tube notes suction spindle head is connected on the nipple of two syringe 5 front ends.
