Abstract
The invention discloses a flat strip-shaped drainage device which is applied to the operation implantation at the pars plana of a ciliary body to treat the refractory glaucoma. Aqueous humor in an eye is led out of the eye and oozed to the lower part of a conjunctiva through aqueous humor drainage ports and aqueous humor drainage grooves, the aqueous humor drainage volume which is needed in the treatment of the refractory glaucoma can be satisfied, the vitreous-body incarceration at an incision and the incision scar are avoided, and the anterior chamber complication is reduced. The special drainage device is processed by adopting material silica gel or absorptive biomaterial, and is provided with two aqueous humor drainage ports, two or three aqueous humor drainage grooves, and two suture holes. One end of the drainage device is an intraocular implanting end which is 3mm from the suture holes; a head takes the shape of a smooth oval flat strip; the aqueous humor drainage ports are respectively arranged in the two corresponding drainage grooves; when in operation, the implanting end is implanted in the eye and is fixed through suture; the other end of the drainage device is an extraocular drainage end which is relatively long and 10mm from the suture holes, and is provided with two or three drainage grooves.
Description
Affiliated technical field
Drainage device special for glaucoma ciliarotomy of the present invention is a kind of aqueous humor drainage device of implanting in the operation of human eyeball's orbiculus ciliaris, is applicable to the intractable glaucoma of treatment.
Background technology
Intractable glaucoma is meant and adopts conventional medicine and routine operation all to be difficult to the glaucoma that proves effective.
Being used for the treatment of intractable glaucomatous aqueous humor drainage device at present on the clinical medicine only is to be applicable to that human eyeball anterior chamber implants.This aqueous humor drainage device is made up of drainage tube and liquid trap.Aqueous humor is discharged to liquid trap outward by drainage tube, is seeped under the outer conjunctiva of eye again, reaches the reduction intraocular pressure, treats glaucomatous effect.But a lot of clinically patient's postoperatives often stop up because of drainage tube or the liquid trap fibers encapsulation is lost the drain function, and intraocular pressure raises, the glaucoma recurrence.The aqueous humor drainage device of anterior chamber's implantation is owing to its drainage tube caliber size of reason of post-operative complication is limited on the other hand, be difficult to obtain to treat the drainage flow of intractable glaucoma requirement, so effect is not too satisfied clinically, and this aqueous humor drainage device complex structure, cost an arm and a leg, be difficult to popularize.
Summary of the invention
In order to overcome the deficiency of existing anterior chamber's embedded type aqueous humor drainage device, drainage device special for glaucoma ciliarotomy of the present invention changes the operation approach at first innovatively, utilizes the orbiculus ciliaris otch that operates; In addition by the novel rational aqueous humor drainage device of design, shape, structure, material and technical the innovation, increase the aqueous humor drainage amount on the one hand, prevent the post-operative complication that anterior chamber's path often causes, prevent on the other hand that vitreous body is excessive, difficult problems such as incarceration and incisional scarization, reach the intractable glaucomatous purpose of treatment.
This drainage device special for glaucoma ciliarotomy is that the technical scheme that its technical problem of solution is adopted is: 1, drainage device is implanted rather than is implanted from angle of anterior chamber from the eye orbiculus ciliaris, to reach when increasing the aqueous humor drainage amount, can not cause multiple complications such as the postoperative anterior chamber shoals yet.2, replace drain tubule and liquid trap with the flat-shaped drainage device that has aqueous humor drainage opening and drainage trough, prevent line clogging.3, the flat-shaped drainage device can prevent the excessive and incarceration of incision vitreous body, can prevent otch surrounding tissue cicatrix and localization by the lengthening and the external drainage end of bifurcated, influence the effect in aqueous humor drainage amount and long term.4, adopt medical silica-gel or water absorption biomaterial also by technical finesse, can reach and keep secular aqueous humor drainage function and reduce the operative incision fibrous scarization.
The beneficial effect of this drainage device special for glaucoma ciliarotomy is can keep intractable glaucomatous aqueous humor external drainage function long-term effectively and reduce the operative incision scarring, and operation technique to be convenient, simple in structure, with low cost.
