Abstract
The invention discloses a Schlemm tube probing and flushing support sleeve and a use method thereof, and relates to the technical field of glaucoma treatment. An inner layer microscopic elastic support (2) is arranged inside an outer layer flushing sleeve (1), and multiple outer layer sleeve wall holes (3) are formed in the outer layer flushing sleeve (1). The design of the double-layer sleeve is adopted, and the effects such as probing, flushing and supporting are achieved simultaneously; the sleeve has proprietary intellectual property rights, and the manufacturing cost and medical costs of patients are reduced; the stability is good, and displacement is not prone to occur; nonuniformity, caused by stitches applied in Schlemm tube plasty at present, of tangential force and supporting is relieved, and dilatation and supporting effects are more exact; the outer layer flushing sleeve can not only conduct probing and dilatation, but also can inject dye of sodium fluorescein and the like, evaluation is conducted on a Schlemm tube and liquidity of a far aqueous humor outflow pathway, and the effect of lowering intraocular pressure after an operation can be judged in advance.
Description
Technical field
The present invention relates to viscous tubule and visit logical flushing rack sleeve and using method thereof, belong to glaucomatous treatment technology field.
Background technology
Glaucoma is irreversibility diseases causing blindness the first in world wide.More than 40 years old crowd's prevalence of glaucoma of current China is 2.3%, blind rate about 30%.Expecting the year two thousand twenty, will there be the glaucoma patient of 21,000,000 in China, produce nearly 6,300,000 blind persons and the vision disabled more than 10,000,000, cause white elephant to patient home and society, be an important public health problem.Glaucomatous pathogeny is also not very clear, the rising of intraocular pressure is the risk factor of currently the only confirmation.Therefore current glaucomatous treatment is concentrated mainly on reduction intraocular pressure, protection optic nerve aspect.Aqueous humor produces and intraocular pressure adjustment is played a crucial role by the dynamic equilibrium of outflow.Under normal circumstances, aqueous humor is produced by the ciliary pigmented epithelium of ophthalmic, flows into aqueous veins and episcleral veins through back room, pupil, anterior chamber, trabecular reticulum, schelemm pipe, collector tube, and the final body that imports circulates.Trabecular reticulum and schelemm pipe are the main resistance positions that aqueous humor flows out.No matter open angle glaucoma or angle closure glaucoma, the intraocular pressure caused mainly due to impaired aqueous outflow raises.But ocular hypotensive agents thing reduces intraocular pressure mainly by the generation suppressing aqueous humor mostly at present, and resisting glaucoma operation treatment, especially most common trabeculectomy is applied at present, it is then by making a transparency cornea fistula mouth, ophthalmic aqueous humor is directly drained under conjunctiva, thus reducing the pressure of ophthalmic.Both approaches does not comply with the physiology of human normal to a certain extent, fails to solve glaucomatous essential problem.How visiting the aqueous humor flow pass under logical normal physiological conditions, re-establish the balance that aqueous humor produces and flows out, thus reducing intraocular pressure, protection optic nerve avoids the direction that apoptosis is glaucoma future therapeutic.
Current existing schelemm pipe holder, as sufficiently expensive in prices such as istent, existence simultaneously comes off still uncertain into its curative effects of factor such as anterior chamber, the problems failing to solve Schlemm pipe far-end aqueous humor outflow obstruction, and clinical practice is also restrained.The optical fibers price applied in viscous tubule dilatation plasty is sufficiently expensive, and some patients schelemm pipe cannot be visited logical simultaneously, causes the wasting of resources.On the other hand, the mechanical pressure of suture is likely to early postoperation again and causes the edema of trabecular reticulum, causes intraocular pressure to raise further.Other also all cause the failure of operation and the generation of related complication such as rejection, the excessive situations such as trabecular reticulum of tearing of thread tension.Develop a kind of cheap, Schlemm pipe that better tolerance, reducing iop are clear and definite to visit logical and timbering material and will bring new hope to glaucomatous treatment.
Summary of the invention
For the problems referred to above, the technical problem to be solved in the present invention is to provide viscous tubule and visits logical flushing rack sleeve and using method thereof.
The viscous tubule of the present invention visits logical flushing rack sleeve and using method thereof, it comprises outer layer irrigating canula 1, the micro-elastic holder 2 of internal layer and outer layer sleeve tube wall hole 3, outer layer irrigating canula 1 be internally provided with the micro-elastic holder 2 of internal layer, outer layer irrigating canula 1 is provided with several outer layer sleeve tube wall hole 3.
As preferably, described outer layer irrigating canula 1 is double-deck sleeve pipe.
The viscous tubule of the present invention visits the logical using method rinsing rack sleeve:
A, conventional making top conjunctival flap and scleral flap, search out Schlemm pipe, cut Schlemm pipe outer wall；
B, from Schlemm pipe side, the broken ends of fractured bone slowly inserts this sleeve pipe, carries out visiting logical to Schlemm pipe；
C, pass this sleeve pipe from the Schlemm pipe opposite side broken ends of fractured bone；
D, slow normal saline or the fluorescein sodium of injecting in this sleeve pipe, spy is led to and judges the unobstructed situation of Schlemm pipe and far-end aqueous humor drainage passage；
E, inject the micro-support 2 of internal layer and slowly withdraw outer layer irrigating canula 1, micro-for its interior internal layer elastic holder 2 being retained in Schlemm pipe, and makes it be expanded to maximum gauge 200um；
Saline injection in f, anterior chamber, observes conjunctiva blood vessel and bleaches degree and scope, it is judged that aqueous humor drainage pathway degree of mobility；
G, tight suture scleral flap and conjunctival flap, operation terminates.
Beneficial effects of the present invention: 1, adopt bilayer sleeve design, have that spy is logical simultaneously, rinse,
The effects such as support；2, there is independent intellectual property right, reduce the medical expense of cost of manufacture and patient；3, good stability, not easily shifts；4, reducing the inhomogeneities of the circumferential force caused by suture because applying in current viscous little Tuboplasty and support, expansion and supporting role are more definite；5, outer layer irrigating canula is possible not only to carry out visit logical, expansion, can inject the dyestuffs such as fluorescein sodium simultaneously, and the patency of Schlemm pipe and remote aqueous humor outflow pathway is estimated, and can the postoperative intraocular pressure lowering effect of anticipation.
Accompanying drawing illustrates:
For ease of illustrating, the present invention is embodied as and accompanying drawing is described in detail by following.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is that the micro-elastic holder of internal layer of the present invention is by the structural representation after injecting.
1-outer layer irrigating canula；The micro-elastic holder of 2-internal layer；3-outer layer sleeve tube wall hole.
Detailed description of the invention:
As shown in Figure 1-2, this detailed description of the invention is by the following technical solutions: it comprises outer layer irrigating canula 1, the micro-elastic holder 2 of internal layer and outer layer sleeve tube wall hole 3, outer layer irrigating canula 1 be internally provided with the micro-elastic holder 2 of internal layer, outer layer irrigating canula 1 is provided with several outer layer sleeve tube wall hole 3.
As preferably, described outer layer irrigating canula 1 is double-deck sleeve pipe.
The viscous tubule of this detailed description of the invention visits the logical using method rinsing rack sleeve:
