Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to a kind of nasolacrimal duct sacculus dilating catheters.
Background technique
Obstruction of naso lacrimal duct is ophthalmology common disease, is often caused by inflammation or wound, patient be often accompanied by shed tears, pyorrhea, pain
Equal malaise symptoms, come big inconvenience and pain to minimal invasive treatment and work belt.Obstruction of naso lacrimal duct can lead to tear and bacterium is stagnant
It stays in lacrimal passage, causes the severe complications such as pyogenic infection, ulcer of the cornea, entophthamia.In addition to this, neonatal dacryocystitis is one
The kind very common congenital eye disease of infant and pediatric ophthalmology common disease, frequently-occurring disease.Conventional Nasolacrimal duct obstruction operation is controlled
Treatment mode has: probing of lacrimal passage, artificial tear duct implantation, lacrimal Laser operation, dacryocystorhinostomy.Probing of lacrimal passage is short-term
It is curative for effect but easy to recur.Lacrimal Laser operation can block the abnormal structure of lacrimal passage in lacrimal passage pipe intracavity resecting with gasification, extensive
The tubular structure of multiple lacrimal passage itself obtains preferable curative effect in terms for the treatment of obstruction of lacrimal passage, but new due to being formed after laser photocoagulation
The surface of a wound, fibroblast proliferation under mucous membrane, cicatricial tissue formed, and occludes lumen again, pure laser Postoperative recurrent rate is high.
Artificial tear duct implantation needs second operation to take out, and in early days because blood clot and secretion cause to block, later period lachrymal sac internal cause can not
The stimulation for absorbing lacrimal canal bracket, causes fibrous connective tissue formation granulation tissue hyperplasia, and blocks lacrimal canal bracket opening,
Cause to be difficult to take out.Dacryocystorhinostomy can effectively cure the nose lacrimal passage of obstruction, but have higher operating difficulty and to patient
Wound is larger, is unfavorable for post-operative recovery, it is easy to which the damage for causing eye and nose destroys original lacrimal passage structure, and face is left
The disadvantages of scar, more patient are not easily accepted by.
Summary of the invention
