Abstract
The utility model discloses an injection and inhalation instrument for ophthalmic operating. The utility model is characterized in that the utility model is composed of an injection and inhalation instrument with a valve for regulating the water stream, a negative-pressure bottle communicated with the injection and inhalation instrument, a negative-pressure source, a manual regulation valve, a selector valve and a pedal adjusting valve. When the clouding cortex is sucked in the domestic excision operation out of the cataract bursa carried out, the method adopted is usually the bimanual suction with hollow needles. The method whose stability is poor can easily damage the corneal endothelium. In addition, the water injection amount is regulated via controlling the perfusion tube by the assistant; because the inner diameter of the perfusion tube is thick, the regulation is inaccurate. According to the situation of the operation, the utility model can arbitrarily regulate the suction force and precisely regulate the water injection amount by the operator via the pedal regulator valve. The utility model which makes the operation convenient is favorable to enhance the operation quality.
Description
This utility model belongs to technical field of medical instruments.
In descending modern day cataract ECCE of microscope or posterior chamber implantable artificial intraocular lenses operation simultaneously, it is a new technique that rises the seventies in the world, along with carrying out of this technology, the cataract injection and inhalation instrument has appearred in the world, have at present cataract injection and inhalation instrument unit and with two types in vitreous cutter and the comprehensive instrument of cataract emulsator, this injection and inhalation instrument function of two types is identical, the switch of instrument is regulated by surgical doctor, and captivation will be regulated by the nurse, and this makes operator feel inconvenience.Usually domestic when carrying out ophthalmologic operation, generally adopt the method for bimanualness empty needle suction, this method poor stability, easy damaged corneal endothelium.Show the domestic two kinds of cataract injection and inhalation instruments that occurred, a kind of injection and inhalation instrument is to annotate to inhale synchronously, in the operation along with erratic excessive by otch liquid, can making at the moment, atrial pressure is tending towards uneven, and in a single day the also difficult correction of imbalance appears, make the suction process difficulty, another kind of injection and inhalation instrument, operator can not directly be controlled negative pressure, need be controlled by other people, this is unfavorable for that operator chooses at random gravitation according to situation in the art, easily accidentally injures normal structure, what of this instrument water injection rate, will control tube for transfusion by the assistant and regulate, the camera oculi anterior capacity is little owing to tube for transfusion internal diameter thick (4mm), so when adjusting and extrusion pipe, anterior chamber's water injection rate is changed significantly, regulate inaccurate.
Main points of the present utility model are a kind of ophthalmologic operation injection and inhalation instruments of annotating suction spindle head, negative pressure bottle, negative pressure source, manual adjustments air valve that comprise.It is characterized in that by the injection aspirator that has flow control valve (1) (2) and be attached thereto logical negative pressure bottle (3), negative pressure source (4), manual modulation valve (5) selector valve (6) and several parts of foot-operated control valve (7) forming.
The said injection aspirator (2) that has flow control valve (1) is formed by annotating suction spindle head (8) and flow control valve (1).The inner chamber top of its flow control valve has a water filling flexible pipe and walks hole (9), and the bottom has an air flue hole (10).One end of flow control valve (1) is connected with notes suction spindle heads (8), and the other end is connected with negative pressure bottle (3) by a pipeline (11).
The purpose of design of flow control valve is: when current through the water filling flexible pipe when the control valve, operator can be regulated discharge arbitrarily according to situation oneself in the operation, has avoided being intended to make current regulate problem improperly because of the assistant can not well understand operator in the past.
Said negative pressure bottle (3) also is communicated with another pipeline (12) and communicates with negative pressure source (4).On pipeline (12), also connect another pipeline (13), be connected to display instrument (14), manual modulation valve (5) and selector valve (6) on this pipeline.
Said selector valve (6) is the top that turns on pipeline (13).The bottom connecting pipe (15) of selector valve (6), the other end of its pipeline (15) is connected to foot-operated control valve (7).
Said foot-operated control valve (7) is to be the T type pedal (16) of bullet by the bottom, be contained in the valve body that spring (17) on the pedal and bottom and sidewall one place have a pore (18,19) and form, the pore (18) of said valve body (7) bottom is located to be connected with the top of connecting leg (15).
The purpose of design alternative valve and foot-operated control valve is: when carrying out extracapsular cataract extraction operation and posterior chamber intraocular lens implant surgery and draw muddy cortex, the patient can regulate captivation arbitrarily by foot-operated control valve, make and draw automatization, reduced and with the hands operated the problem that empty needle is drawn camera oculi anterior normal tissue injury due to the cortex instability in the past.Because the patient is own to foot adjusting captivation, so avoided other type to need the nurse help to regulate institute's suction that causes problem improperly, has overcome the deficiency of simple manual modulation valve instrument.
When being expert at other operation, can adjusting selector valve and cause on the manual control valve, remove hematocele and pigmented film to be suitable for operations such as ball content ecochleation, nasal cavity lachrymal sac anastomosis and lachrymal sac excision, but a tractor serves several purposes, bring convenience to the doctor, shorten operating time, alleviate patient's misery.
Description of drawings and embodiment.
Accompanying drawing is the sketch map of explanation ophthalmic injection and inhalation instrument.
Embodiment:
Critical piece of the present utility model comprises the injection aspirator (2) that has flow control valve (1), and a termination of control valve (1) has the suction spindle head (8) of notes.The other end is linked to each other with negative pressure bottle (3) by pipeline (11), negative pressure bottle links to each other with negative pressure source (4) by pipeline (12) again, on pipeline (12), pick out a pipeline (13) again, be connected with display instrument (14) on this pipeline, manual modulation valve (5) and selector valve (6), pipeline (15) is connected in the bottom of selector valve, and foot-operated control valve is connected on the top of pipeline (15).
