Abstract
The utility model relates to a self-lock silicon-oil aspirator, comprising a soft needle, an aspirating tube, a plunger and a plunger rod, wherein the soft needle is sleeved at the front end of the aspirating tube, the plunger is fixedly positioned on a head portion of the plunger rod, and the plunger moves axially inside the aspirating tube. The plunger rod is manufactured as an integral body with uniformly distributed fan blades structured along the same axial and the same diameter. Each fan blades of the plunger rod is axially and uniformly equipped with a groove along the same diameter. Flanges of chases which can clamp the fan blades of the plunger rod are uniformly disposed on the inner edge of the aspirating tube along the same diameter. The utility model employs stable suction mode to automatically aspirate silicon-oil, thereby having the advantages of being simple, secure, fast, high effective, economical and the like. Besides, the aspirating speed is relatively uniform and fast, effectively reducing the surgery time, improving the surgery efficiency, reducing the bitterness of patients and greatly reducing the expenditure of medical care. The utility model is adaptable for grass-root units.
Description
Technical field
This utility model belongs to medical instruments field, is the employed a kind of self-locking silicone oil aspirator of ophthalmologic operation.
Background technology
Eyes are visual organ that body weight for humans is wanted, mainly by eyeball, look the road and appendages three parts are formed.And the vitreous body tissue as one of vitals tissue of vision, occupy 4/5 of eyeball total capacity.Vitreous body is the transparent colloid tissue within the eye, and major function is that light can be passed through smoothly to arrive on the retina.The forfeiture of vitreous body transparency (muddiness, degeneration, propagation) is modal pathological change, and in a single day this tissue pathological changes takes place, can cause the multiple complications of eye to take place, thereby can influence or lose visual function.
Vitreous body tissue as serious pathological change takes place need oozy glass body cutting operation, the order of severity that postoperative ophthalmic implant is looked the eye pathological change, the lighter fills artificial vitreous or long-acting gas, weight person's filling silicon oil.Gas can absorb voluntarily, but silicone oil is difficult for filling ophthalmic for a long time because of its physicochemical property, treats that the ophthalmic pathological changes needs to take out after stable.Silicone oil concentration is 1300-5000Cs, and the concentration of domestic application is all at 5000Cs, and the silicone oil viscosity is higher.The common removing method of silicone oil is: use the special-purpose armarium-phaco of ophthalmology, utilize negative pressure 500mmhg that silicone oil is taken out.Though this operation method is laborsaving, the preceding preparation of art is loaded down with trivial details, and materials used is more, and operating time is grown (about about 30-60 minute), and the big negative pressure of equipment makes complication easily takes place in the operation process, the safety less stable, and surgery cost is higher.The ophthalmologist attempts to study several different methods and solves.Attempt with manually extracting silicone oil as some doctor, because of the silicone oil viscosity is big, manually the dynamics of extraction method varies with each individual, and has some inconveniences.Therefore studying a kind of practicable method is pendulum problem demanding prompt solution in face of the ophthalmologist.
By retrieval, also do not find special-purpose manual silicone oil aspirator at present.
Summary of the invention
But the purpose of this utility model is to provide a kind of simple in structure, easy to operate and self-locking silicone oil aspirator by stable negative pressure auto-pumping ophthalmic silicone oil.
The technical scheme that this utility model is taked is:
A kind of self-locking silicone oil aspirator, constitute by soft syringe needle, suction cylinder, plunger and plunger rod, soft pinhead sleeve is contained in the suction cylinder front end, the plunger rod head installs plunger and this plunger axis shift in suction cylinder, it is characterized in that: plunger rod is integrally formed coaxial with the uniform fan wing structure in footpath, fan wing is uniform in the axial direction all is shaped on groove with the footpath for each of this plunger rod, but at suction cylinder inner edge position with the uniform flange that is shaped on the made recessed noise of the setting-in plunger rod fan wing in footpath.
And the uniform fan wing quantity in coaxial footpath together that described plunger body is made is 2-6.
And the uniform in the axial direction groove quantity that all is shaped on the footpath of each fan wing of described plunger rod is 3-10.
And described the uniform made number of flanges in same footpath is 1-6 at suction cylinder inner edge position.
And, on the suction cylinder outer cylinder, axially being shaped on scale, this scale is corresponding with the made recessed noise of the plunger rod fan wing.
And the uniform made flange in same footpath, described suction cylinder inner edge position is built in the uncovered position of suction cylinder.
Advantage of the present utility model and good effect are:
1. with the uniform flange that can clamp the made recessed noise of the plunger rod fan wing that is shaped in footpath, this flange can have in suction cylinder under the pressure condition by the column spinner stopper rod and groove is installed on the auto-lock function of realizing plunger rod on the flange of suction cylinder this silicone oil aspirator at suction cylinder inner edge position.Aspirate silicone oil for the ophthalmologist, plunger rod can be extracted assigned scale and the column spinner stopper rod is stuck on the flange, the negative pressure in the suction cylinder can be in suction cylinder auto-pumping silicone oil; Because this negative pressure is more stable, the flow velocity that therefore aspirates silicone oil is comparatively even, and pumping velocity is very fast, generally can finish the silicone oil of 5-8ml in about 5-10 minute, has reduced operating time thus, has improved operation efficient, has alleviated patient's misery.
2. this silicone oil aspirator greatly reduces patient's health care expenditures owing to adopt manual mode instead of dedicated armarium.In addition, this silicone oil aspirator also has the function of disposable syringe, can be used as common syringe and uses, and function ratio is more.
3. this utility model overall structure is simple, rationally novel in design, adopt stable negative pressure mode auto-pumping silicone oil, and the suction flow velocity is comparatively even, pumping velocity is very fast, has reduced operating time effectively, has improved operation efficient, alleviate patient's misery, also greatly reduced patient's health care expenditures.
