Abstract
The utility model relates to ophthalmosurgery surgical equipment, in particular to a lacrimal canaliculi stent, which is used for supporting and communicating the lacrimal canaliculi of a patient. The lacrimal canaliculi stent is characterized by comprising a support tube (1),the support tube (1) is a cylindrical tubular structure with two through ends, and a ball sac (2) is disposed on the support tube (1). The lacrimal canaliculi stent can realize full support, expansion and drainage effect on the body of the lacrimal canaliculi of the patient. By the aid of the lacrimal canaliculi stent, liquid medicine is more effective in an irrigation function, fester and lesion positions can be directly irrigated, and the liquid medicine can be added in a more concentrative manner. The lacrimal canaliculi stent can be widely applied to blockage due to inflammation, is used as a main method for treating lacrimal canaliculi rupture caused by trauma, can realize supporting and bridging efficacy and greatly improves permanent success rate of surgeries. In addition, tube arrangement for the lacrimal canaliculi stent can be easily implemented, surgical risks are low, the lacrimal canaliculi stent can be fixed in a buried suture manner, barbs, the ball sack and a structure consisting of two larger ends and a smaller middle portion can be disposed on the lacrimal canaliculi stent so as to prevent the lacrimal canaliculi stent from slipping and being blocked.
Description
Technical field
This utility model relates to the eye surgery device, especially a kind of lacrimal ductule support that is used for lacrimal ductule support, conducting.
Background technology
A pipeline is arranged between people's canthus and the nasal cavity, be called lacrimal passage, be made up of puncta, lacrimal ductule body, tear house steward, lachrymal sac, nasolacrimal duct from top to bottom, its function is the drain tear.If lacrimal passage stops up because of reasons such as narrow, inflammation, wounds, tear drainage is obstructed, a large amount of tears is accumulated in the lachrymal sac, will cause multiplying in a large number of antibacterial, thereby cause chronic dacryocystitis, find that through the lacrimal passage splanchnoscopy reason of lacrimal passage postoperative recurrence is needed badly and in time taked the associated treatment measure based on granulation and hypertrophy.
Laceration of lacrimal canaliculus is one of common ocular injury emergency case, and the lacrimal ductule of surgical stapling fracture is the only method of this emergency case of treatment.The nasolacrimal anastomosis method of report is multiple at present, and the lacrimal ductule supporter also has lumbar anesthesia pipe, silica gel tube silk thread etc. to have nothing in common with each other.
The ring-type tissue that the lacrimal ductule broken ends of fractured bone is white in color, make the lacrimal ductule supporter with the lumbar anesthesia pipe and have many drawbacks, the lumbar anesthesia pipe is thinner, and the lacrimal ductule broken ends of fractured bone is difficult for being close to and sewing up, and also bring difficulty for corresponding stitching of endocanthion portion, put Guan Houhui and find to cause eversion of lacrimal punctum, laceration of canaliculus.Though silica gel tube is soft, be difficult for putting pipe, slippage easily.
Because the special physiological structure of lacrimal ductule, the thin and inside of its tube chamber does not have skeleton to support, and after pipe was put in operation, the soft tissues such as granulation, cicatrix of very easily growing resulted in blockage.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and a kind of lacrimal ductule support is provided.
The technical solution of the utility model is:
A kind of lacrimal ductule support, it comprises stay pipe, described stay pipe is the cylindrical tubular structure that two ends connect.
Described stay pipe is provided with sacculus.
Described stay pipe one end is provided with horn mouth.
Two ports of described stay pipe are respectively equipped with a horn mouth.
The outer wall of described stay pipe is provided with one or more projection granules.
Described stay pipe is provided with agnail.
Described stay pipe is provided with wears fairlead.
The beneficial effects of the utility model are:
1, this utility model is one-body molded makes, simple for production, bulk strength height, long service life;
2, this utility model can play the omnidistance expansion drainage that supports to the lacrimal ductule body;
3, this utility model makes that in use the flushing action of medicinal liquid is more effective, can directly wash the suppuration diseased region, makes applying of medicinal liquid concentrated, can directly effectively arrive areas of inflammation;
4, of the present utility modelly can prevent to injure cornea, the uncomfortable disease after having avoided causing pathological changes and having put pipe has effectively improved patient's comfort level.
5, when settling lacrimal ductule support of the present utility model, the end of draught line can be lain in the fairlead of wearing of lacrimal ductule support end, just lacrimal ductule support of the present utility model can be delivered to assigned address, highly effective and safe smoothly.
6, lacrimal ductule support of the present utility model can be widely used in the obstruction that inflammation causes, causes the main means of laceration of lacrimal canaliculus as wound, and the effect of can bring into play support, putting up a bridge improves the permanent success rate of operation greatly.
7, lacrimal ductule of the present utility model props up and mounts pipe easily, and operation risk is little, can adopt the mode of sunkening cord to fix, and the little structure in the big centre in agnail, sacculus and two can be set on it, can effectively prevent slippage and obstruction,
8, lacrimal ductule support of the present utility model reproduces with lacrimal point applicable to lacrimal ductule and reproduces.
