Compared with prior art, advantage of the present utility model just is:
When 1, adopting artificial lacrimal duct of the present utility model that the patient is implemented the lacrimal passage tube planting operation, earlier drainage tube not being established an end of collar flange and wing stator implants in patient's the lacrimal ductule through last puncta or following puncta, and should hold and draw from nasal meatus, introduce lacrimal ductule until an end that drainage tube is provided with the wing stator through last puncta or time puncta, and be positioned puncta or descend the puncta place by the end of collar flange with drainage tube.Make artificial dacryocanalicular silica gel material and be and have necessarily elasticly, the wing stator is located on the outer wall of drainage tube, forms angle with drainage tube, during its implanted patient's lacrimal ductule, can draw in, is convenient to install; After drainage tube was located by collar flange, the wing stator can provide tension force, plays fixation; And wing stator volume is little, and is few to the compressing area of conjunctiva, can alleviate patient's foreign body sensation.
2, because the angle opening of wing stator and drainage tube towards collar flange, is that small end is introduced into when the wing stator enters lacrimal ductule, be convenient to install, can alleviate patient's pain.
3, collar flange is provided with the drain scrobicular ring, is convenient to the collection of tear, helps tear is imported in the drainage tube.
4, drainage tube is arranged with a guiding steel wire away from an end of collar flange, and guiding steel wire rigidity is better, is convenient to its implant into body lacrimal ductule, can play the effect that the guiding drainage tube is implanted; The guiding steel wire end is provided with jut, can pass through crochet hook tractive guiding steel wire easily, and guiding steel wire is taken out from nasal cavity, is convenient to artificial lacrimal duct is implanted lacrimal passage.
