Description

Vitreous chamber suction and injection aid

Technical field

This utility model relates to eye medical instruments field, is specially the suction of a kind of vitreous chamber and injection aid.

Background technology

Along with age-related macular degeneration, diabetic retinopathy, the retinal vein occlusion etc. improve constantly with the retinopathy sickness rate that cystoid macular edema and choroidal neovascularization are main manifestations, various treatment means is targetedly used widely clinical, and treatment means comparatively conventional at present comprises: Fundus laser treatment and intravitreal Drug therapy.Wherein the intravitreal anti-neovascularization growth factor has become the therapeutic modality of a lot of doctor's first-selection.But, present stage, the operational approach of intravitreal was main or carry out subjective individuation operation according to the international operating guidance constantly updated, the generation of injection related complication depends on experience and the operation skill of doctor to a great extent, especially select the position of inserting needle, angle and the degree of depth these in, this also makes under medical environment comparatively nervous at present, intravitreal can not be popularized at basic hospital, even if be also in most cases by the doctor of the high age and service seniority in provincial, and municipal level hospital or have the doctor of Vitrectomy experience to complete.

In a word, clinically or in scientific experiment intravitreal or sampling main still foundation operating guidance are operated in conjunction with personal experience at present, there is the problem such as retina shedding, intraocular infection, injection port seepage caused owing to lacking experience in operation.

Summary of the invention

The purpose of this utility model is to provide a kind of novel vitreous chamber to aspirate and injection integrated auxiliary device, by medelling simple to operate, can reduce or reduce at present owing to operating the lack of standardization or intraocular injection complication caused of lacking experience.

This utility model adopts following technical scheme to realize:

A kind of vitreous chamber suction and injection aid, comprise main connector, the lateral symmetry of described main connector arranges connecting lateral plate, and described connecting lateral plate arranges syringe rest area; The bottom of described main connector arranges cornea running-on, arranges sclera cover outside described cornea running-on; The top of described main connector arranges hand-held apical ring.

During normal use, after the topical anesthesia of injection eye, by hand-held apical ring, by cornea running-on position accurately and patient's limbus of corneae connect, then dextrorotation rotary device about 30 ° centered by corneal vertex, thus make the bulbar conjunctiva on sclera cover surface that a certain amount of displacement occur, the syringe that medicine is housed is positioned over corresponding syringe rest area and carries out drug injection.As larger milliliter number drug injection need be carried out, for preventing the problem operating the rising of rear patient's intraocular pressure, syringe can be placed from offside syringe rest area, pump out precalculated volume vitreous chamber amount of liquid, then cartridge syringe will be housed directly inject the medicine of scheduled volume.The position of placing due to syringe is 3.5-4.0mm after corneoscleral junction, in auxiliary device, the annexation of connecting lateral plate and syringe rest area is determined by calculating, ensure that in practical operation, syringe keeps specific injection angles, so can farthest reduce accidental injury crystalline lens, reduce iatrogenic cataractous incidence rate; In addition, by dextrorotation rotary device before injection, there is displacement to a certain degree in bulbar conjunctiva, complete in injection, extract injection needle and bulbar conjunctiva resets after removing injection device, play closed injection pin hole, avoid the problem of drug leakage, ensure that safety and the effectiveness of injection.

Compared with operating with subjective experience, this utility model device realizes intravitreal position, injection angles Accurate Design, and realized by two injection ports that suction and injection operation are simultaneously simplified, safe, the risk brought thus the subjective operation of reduction and patient compliance's difference eyeball in operation are not independently shifted, operation sequence is simplified, promotes health care safety.

The advantage that this utility model has is as follows:

1, hand-held apical ring and cornea running-on can fix eyeball position, prevent patient from working poor in operation or occur not moving from dominant eye the operational risk brought.

2, rotate sclera cover, realize the displacement of scleral surface conjunctival tissue, after injection completes, conjunctival tissue automatically resets and plays the effect of closed injection mouth.

3, the syringe rest of accurate Calculation design, reduces iatrogenic cataractous generation, injection site, inserting needle direction and depth of needle can be limited preferably, ensures the safety of operation further.

4, double injection suction entrance, injection and suction once can complete without on the basis of repeatable operation.

This utility model is reasonable in design, and the suction of this vitreous chamber and injection aid can the operation more standards, safer of assist physician, effectively reduce the generation of iatrogenic injury and intravitreal related complication, have good market application foreground.
