Fig. 2 is the schematic diagram of suction syringe needle.
Fig. 3 is the schematic diagram of perfusion syringe needle.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
A kind of ophthalmologic operation aspiration needle device as shown in Figure 1 comprises suction channel 1, suction syringe needle 2, perfusion syringe needle 3, union joint.
Suction channel 1 is one section of flexible pipe; Suction syringe needle 2 as shown in Figure 2 adopts No. 5 Syringe needle Irrigators of band side opening, and syringe needle is anterior is converted into 135 ° of angles from head end 10mm place in suction; Pouring into syringe needle 3 is as shown in Figure 3 that No. 8 conventional syringe needles cut off needle point, is polished smooth by head end, is being converted into 135 ° of angles from head end 10mm place; Union joint is provided with two altogether, is respectively syringe needle union joint 41 and injection union joint 42, and syringe needle union joint 41 and injection union joint 42 are arranged on the two ends of suction channel 1 respectively.
Small incision cataract surgery, the note suction spindle head entering ophthalmic from main otch brings certain difficulty to the removing of otch hypopallium, but can otch hypopallium be removed clean of crucial importance again, because it may sink to pupil central area and affect one's power of vision, and residual cortex of lens also can stimulate iris to produce inflammatory reaction; In addition there is the formation of report intraocular lens anterior membrane to have suitable relation with residual lens cortex, also have experimentation to show that cortex of lens can induce iris neovascularization.
Two incision group comparatively safety also can aspirate cortex more up hill and dale than single otch group.Cortex remain, Poster capsulorhexis complication are less; Although operative incision is more than single otch group, Postoperative visual acuity and single otch group no difference of science of statistics, the average Loss Rate of endothelial cell, postoperative complication and operating time do not increase.
Two incision cortex suction system is relative to routine two-tube pin list otch suction cortex in manual small incision cataract surgery, and because each side otch is relatively little, more main otch tunnel is shorter, not easily occur because apparatus to the sled of otch pressure obliteratio camerae anterior cause inhale by mistake after capsule.Perfusion use 8 syringe needle, be greater than suction use No. 5 syringe needles, such groundwater increment is just greater than aspiration, is easy to form stable anterior chamber.Suitable raising perfusion pressure, forms darker anterior chamber, and for suction cortex provides more working place, not easily cause the damage of iris, thus after-operation response is light.And stable darker anterior chamber can reduce the generation of the complication such as Poster capsulorhexis; Meanwhile, because perfusion and suction are respectively two passages, can adopt from the alternately suction of two passages for the cortex under otch, so just there is not operation blind area.Because extensively carrying out of present cataract operation strengthens with the control consciousness of cataract patient, the cataract in overripe stage and period of maturation is fewer and feweri.
Present stage metabolic cataract and non-mature cataract Transparent Cortex more, and comparatively thickness, use conventional two-tube pin suction more time-consuming, sometimes need to take the bulk cortex held out of anterior chamber, so just need two-tube pin turnover anterior chamber repeatedly, anterior chamber will repeatedly disappear and be formed, the probability of capsule, cystoid macular edema and infection after will increasing brokenly.And this structure does not need syringe needle turnover anterior chamber repeatedly, under adequately sustained perfusion, can be ground within the eye by two pins the cortex of bulk and thickness and be easy to sucking-off, easily suction is clean smoothly for cortex, so just can reduce the incidence rate of after cataract, shorten operating time, and economic, practical.
In economically less developed region or some grass-roots unit, when temporarily without cataract surgery equipment or technology, grasp and carry out technique there is realistic meaning.Certainly, because the increase of otch quantity may increase postoperative infection risk, the postoperative watertight more will noting each otch, the antibiotic medicine of strict preoperative and postoperative is applied and carries out detailed health mission to patient, the generation of avoiding infection; Meanwhile, when using the misoperation of this technology, to the ophthalmic injuries of patient, the mainly damage of corneal endothelium and breaking of rear capsule.Have statistics, all kinds of complication of cataract operation are about 51.02%.Wherein, the complication of cornea accounts for very large part.In cataract operation, above common complication is relevant with experience, the cooperation of assistant, microscopical use and definition with the operation skill of operative doctor, so, before the operation of this suction system of practical application, patient must repeat under the microscope by animal eye, coordinates exercise with assistant; Suction force should be controlled well when assistant aspirates, can not excessive suddenly and capsule after damage, and constantly sharpen understanding in practice, by this bimanualness technology of grasp of the skilled operation of short-term, postoperative complication incidence rate is dropped to minimum.
Two incision suction cortex technological borrowing bimanual microphacoemulsificaandn ultrasonic emulsification technology, by the operating theater instruments simply transformed, preferably resolves the problem of suction cortex, but more economical practicality.In a word, in small incision in cataract operation, by the application two incision surgical effect that coordinates equipment of the present utility model can reach desirable, be especially better vast cataract patient service at basic hospital.
