Abstract
An artificial entire lachrymal canal relates to an ophthalmology medical appliance, which comprises two different size artificial canals. The canaliculus is the artificial lachrymal duct and the heavy canal is the artificial nasolacrimal duct. The canaliculus is provided with a plurality of outlet holes at the back end. The up side of the heavy canal is provided with a neck and its assorted hole for fixing, while the down side is provided with a spare hole. The middle and down parts of the canaliculus are installed in the heavy canal and the middle part is curved in the neck. The utility model has the simple structure, the convenient and fast production and application and the tears transfusion function instead of the lachrymal canal which enables it to treat all lachrymal canal obstruction.
Description
Technical field
This utility model relates to a kind of ophthalmic medical utensil.
Background technology
Ophthalmology lacrimal passage disease is China's commonly encountered diseases, frequently-occurring disease.At present, because the popularization of lacrimal passage intubation technology, success rate of operation descends, and the difficulty that the lacrimal ductule damage that causes is thus performed the operation once more is very big.In addition, because the increase of ocular injury, laceration of lacrimal canaliculus is also more and more, and the laceration of lacrimal canaliculus success rate of operation is not high, and second operation is also pretty troublesome, and some patient causes the tear that overflows throughout one's life.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of complete artificial tube of lacrimal passage, supports the expansion lacrimal passage, plays the effect of dredging tear, thus the lacrimal passage disease that the treatment a variety of causes causes.
The technical scheme that its technical problem that solves this utility model adopts is; Complete artificial tube of lacrimal passage adopts thick, thin two kinds of adopted pipes to combine, tubule footpath be that lacrimal ductule justice is managed, its rear portion correspondence is provided with some outflow holes, what caliber was thick is nasolacrimal duct justice pipe, and its top one side is provided with draw-in groove and supporting with it fixing hole, and nasolacrimal duct justice pipe lower part equipment is used the hole, fixing hole and standby hole are corresponding open-work, lacrimal ductule justice pipe middle and lower part places in the nasolacrimal duct justice pipe, and middle bent places in the draw-in groove of nasolacrimal duct justice pipe upper end, realizes that the justice pipe substitutes the effect of lacrimal passage.
Adopt good effect of the present utility model to be; Complete artificial tube of lacrimal passage is simple in structure, and it is convenient and swift to make application, laceration of lacrimal canaliculus anastomosis operation success rate height, and long service life, the patient has no adverse reaction and sequela, has successfully solved the difficult problem that laceration of lacrimal canaliculus coincide and repairs.
