Abstract
The utility model relates to the technical field of medical apparatus, and relates to an ophthalmologic syringe. The ophthalmologic syringe comprises an injection tube and a suction tube which are connected into a whole, wherein a piston is mounted inside each of the injection tube and the suction tube in a sliding manner; each piston is connected with a transmission rod; an injection needle is arranged at the end part of the injection tube; a suction needle is arranged at the end part of the suction tube; both the injection tube and the suction tube adopt a cylindrical structure with scales; a gear driven by a power unit is arranged between the two transmission rods; a tooth space meshed with the gear is formed in each of the two transmission rods; the pinhead ends of the injection needle and the suction needle are arc; and a plurality of through holes are formed in the pinhead ends. According to the ophthalmologic syringe, an electromotor driving device is adopted to drive the gear, so that synchronized injection and suction operations with equal quantity are achieved; the operation is swift and convenient; the work burden of an medical worker is relieved; unnecessary damage to a patient, caused by the medical worker due to fatigue, is avoided; and the operation effect is guaranteed.
Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of ophthalmology injection aspirator.
Background technology
The clinical ophthalmology operation will be washed eye usually, removes in the operation even more important for cataract.In general, irrigation and disinfection to be carried out before the art, in art, more wound surface will be in time cleared up.Because the requirement of ophthalmic anterior chamber pressure is constant when operation, promptly be to keep anterior chamber's pressure constant when drawing anterior chamber's residual liquid, must be synchronous toward interior fluid injection.
Existing ophthalmology injection aspirator, the medical worker is when operation, both the speed of GPRS notes suction changed the angle of annotating the position of inhaling and being also noted that the notes suction again, medical worker's work load is heavy, tired easily, for example hand vibration, needle body may cause damage to eyeball, perhaps annotate and inhale position and the mismate of annotating suction speed, the effect of influence operation.
The utility model content
The purpose of this utility model is to provide a kind of ophthalmology injection aspirator, be intended to solve the ophthalmology injection aspirator that prior art provides, medical worker's work load is heavy, tired easily annotating when inhaling operation, and patient is caused unnecessary damages or influences the technical problem of surgical effect.
This utility model is to realize like this, the ophthalmology injection aspirator, comprise two syringes that connect as one and suction tube, all be slidingly fitted with piston in described syringe and the suction tube, two described pistons respectively connect a drive link, the end of described syringe is provided with entry needle, the end of described suction tube is provided with aspiration needle, described syringe and suction tube are graduated columnar structured for indicating, be provided with the gear that drives by power set between the two described drive links, two described drive links are provided with the teeth groove with described gears engaged, and the needle end of described entry needle and aspiration needle is arc and is provided with several through holes.
As a kind of improvement, described entry needle and aspiration needle are combined as a whole and form two-chamber notes suction spindle head.
As further improvement, the described two-chamber notes suction spindle needle stand of portion end to end is provided with handle.
Owing to adopted technique scheme, the beneficial effects of the utility model are: be equipped with piston in syringe that is wholely set and the suction tube, when starting power set, the power set driven gear rotates, teeth groove engagement on gear tooth and two drive links, the drive link promotion piston that drives in the syringe moves inwards, the drive link traction piston that drives simultaneously in the suction tube outwards moves, and the two-piston range of movement is equated, the amount of liquid that makes syringe and suction tube discharge and suck equates, realize the suction of synchronous equivalent notes, ophthalmic anterior chamber constant pressure when guaranteeing operation; Inhale operation owing to adopt the motor driver driven wheel to realize annotating, alleviated medical worker's work load, avoid because medical worker's fatigue causes unnecessary damages to patient, when for example causing that in medical worker's fatigue hand tremor is trembled, the drive ejector sleeve trembles and can not cause trembling of needle body, avoid needle body to contact, guarantee surgical effect with the unnecessary of eyeball; The needle end of entry needle and aspiration needle is arc and is provided with several through holes, when guaranteeing to annotate the suction effect, has avoided sharp-pointed needle point that eyeball is caused damage, causes syringe needle to block when avoiding draws substance simultaneously, and influence is annotated and inhaled effect.
Entry needle and aspiration needle are combined as a whole and form two-chamber and annotate the suction spindle head, and compact conformation is easy to operate during use, and two-chamber is annotated suction spindle and on the needle stand of portion handle is set end to end, is convenient to install syringe needle, avoids the direct contact needle of hand to pollute.
