Abstract
The utility model relates to a lacrimal passage drainage stent, in particular to a micropore drainage stent with micropores and fixed tubes, being suitable for the treatment of lacrimal passage obstruction. The utility model reserves the advantages of the existing retrograde naso lacrimal duct intubation, and takes advantage of the micropore siphon theory on the lacrimal passage drainage stent and the fixed tubes under the stent, preventing the embedded micropore drainage stent from falling off. Because of the osmosis function of the pores on the micropole lacrimal passage drainage stent, medical staff can wash the stent and the lacrimal passage conveniently. When the medical staff medicate, medical liquid can be infiltrated by the micropole lacrimal passage drainage stent; inflammation can be relieved and resisted; reconglutination and reconstruction can be prevented. The utility model has the advantages of simple structure, low cost, easy planting and taking, convenient handling, and evident curative effects.
Description
Technical field
This utility model relates to the probing of lacrimal passage support, and particularly a kind of micropore probing of lacrimal passage support that has micropore and fixed sleeving uses when being suitable for the hospitalize obstructed lacrimal passage.
Technical background
Owing to the chronic dacryocystitis that stenosis or occlusion causes appears in lacrimal ductule, tear house steward, lachrymal sac, nasolacrimal duct, simple property obstruction of naso lacrimal duct is common ophthalmic diseases.This sick present Therapeutic Method one is to use the pulsed YAG laser lacrimal passage plastic surgery, the 2nd, implement the naso lacrimal duct intubation that drives in the wrong direction.Though the former can obtain curative effect preferably, because of the equipment price costliness, general curative mechanism is unable to be purchased; The latter implants drainage stent, rebuilds the nasolacrimal duct passage, recovers the physiology circulating function, and it is cheap to implant the probing of lacrimal passage support, and certain curative effect is arranged in the recent period, and face do not have vestige, and the patient is acceptant.But the drainage stent that the patient implants is easily got rid of voluntarily, is come off, and drainage stent can't clean, no cleaning function, still have year in and year out by the possibility of secretions and tear clogged with deposits, even medical worker's administration, do not reach antiinflammatory, antiphlogistic purpose yet, thereby cause adhesion again, the generation of congestion situations again because of drainage stent has infiltration function.
Summary of the invention
The purpose of this utility model provides a kind of micropore probing of lacrimal passage support, it is when keeping existing probing of lacrimal passage support naso lacrimal duct intubation advantage, drainage stent just can not come off voluntarily once implanting, and be convenient to the medical worker and wash support and lacrimal passage, during medical worker's administration, the medicinal liquid porous plays antiinflammatory, antiinflammatory action to lacrimal passage, can prevent adhesion again, block again, thereby improve medical effect.
This utility model is finished with following method: this utility model is made up of probing of lacrimal passage support, cus lacrimalis siphon hole, lacrimal ductule hole, lachrymal sac hole, nasolacrimal duct hole and sleeve pipe.
The probing of lacrimal passage support adopts the medical grade silicon rubber pipe to make.There are three cus lacrimalis siphon micropores the position, intermediate portion, i.e. cus lacrimalis siphon hole, and a fixed sleeving is arranged at the bottom of the lateral symmetry in this hole and uniform distribution lacrimal ductule hole, lachrymal sac hole, nasolacrimal duct hole, probing of lacrimal passage support.Utilize the siphon principle and the telescopic fixation of above-mentioned all micropores that micropore probing of lacrimal passage support can not come off after implantation voluntarily.Because of the infiltration function in all holes of micropore probing of lacrimal passage support, make the medical worker can conveniently wash support and lacrimal passage again, during medical worker's administration, medicinal liquid plays antiinflammatory, antiinflammatory action by the micropore permeation on the support.During use, respectively send into a nose lacrimal passage draught line made from No. zero silk thread through upper and lower tear stains, lachrymal sac is gone in this line upper end, pulling is up and down removed and is blocked tissue, again with guide line tractive micropore probing of lacrimal passage support termination gently, go into to following lacrimal point from the nostril, go into to the nostril from last lacrimal point again, micropore probing of lacrimal passage support is planted in the nose lacrimal passage, extract the support lead out, reuse stricture of vagina formula pincers expanded casing, insert the bottom of micropore probing of lacrimal passage support, cut off unnecessary support, send into the nostril.When forward washing, insert cus lacrimalis siphon hole, just flushable support and lacrimal passage with pure No. 5 syringe needle.During back flush, pull out support termination, nostril, insert micropore probing of lacrimal passage support pore, just flushable support and lacrimal passage with pure No. 5 syringe needle.Use same quadrat method, the medical worker can give patient's medication, to improve curative effect.
This utility model is simple in structure, easily plants, easily gets, and is easy to operate, implant micropore probing of lacrimal passage support and can not come off voluntarily, flushing, convenient drug administration are effective, can prevent adhesion again, the generation of blocking again, use this utility model is cheap, and is evident in efficacy, has obvious social.
