Description
Technical field
The utility model relates to the field of medical instrument technology, specially a kind of stacked set for dacryocystorhinostomy
Pipe.
Background technique
Chronic dacryocystitis is apt to occur in female patient, it is treated at present in addition to the traditional operation of ophthalmology, most common method
It is dacryocystorhinotomy under transnasal endoscopic, has carried out at home nearly more than 20 years, however for Chinese women, lachrymal sac
And the volume of nasal cavity is relatively narrow, be easy to cause at pore-creating adhesion narrow or even locking, leads to operative failure and recur, even
It recurs again.And how to avoid always perplexing clinical problem, most of existing implanted device be for traditional ophthalmologic operation and
Design, it is not appropriate for the use of intranasal arthroscopic diagnosis, and there is implantation and be stranded in the device that Transnasal endoscopy operation few in number uses
The problems such as difficulty, complication is more and comfort is poor.
The existing implanted device that can be used for nasal endoscopes dacryocystorhinotomy is mostly lacrimal passage drainage tubes, is by upper and lower
Probe respectively enters upper and lower puncta and turnes down at pore-creating, then is pulled two end of probes in nasal cavity by draw hook, and
Knotting is fixed at pore-creating.The implantation of existing lacrimal passage drainage tubes is difficult, and time-consuming for tractor implantation, nose Endoscopic Knotting it is difficult,
It is time-consuming and be difficult to be accurately positioned at pore-creating, it is unfavorable for the pairing of bronchia mucosal valve Yu lachrymal sac wall, needs upper and lower puncta simultaneously
Implantation, may cause the complication such as shearing splitting puncta, and endocanthion has pipeline to occupy, and the strong comfort of foreign body sensation is poor, due to being real
Heart body, excessive tear aggravates during implantation, easy infection, and most importantly, and irrigation of lacrimal passage is not during implantation for prior art
It is convenient.
Utility model content

Between pass through the air ring that is fixed on internal surface of sleeve pipe.
In addition, the utility model additionally provides a kind of preparation method that casing is stacked for dacryocystorhinostomy, including
Following steps:
Step 100 chooses hollow silica gel catheter, and pierces through shape with syringe needle respectively in the end face center at silica gel catheter both ends
At the hollow microporous of connection as drainage general pipeline, and the hollow microporous to drain the both ends general pipeline draws as the fixed installation of center axis
Flow branch pipe；
Step 200 carries out frosted to the end face on the outside of drainage branch pipe, and adds inside longer one end wherein ellipse
Circular drainage disk adds end standing screw on the outside of shorter one end；
Drainage tube is heated moulding according to shape need by step 300 under the conditions of 50-60 DEG C, naturally cold after thermoplastic solid
But, it and carries out disinfection spare.
Compared with prior art, the utility model has the beneficial effects that the utility model implantation is convenient, it is only necessary to small by lower tear
At the i.e. reachable pore-creating of point implantation drainage general pipeline and drainage branch pipe, matched with clinically widely used lacrimal probe, no
Additional traction device is needed, it is only several minutes time-consuming, and without complex process such as knottings in nasal cavity, it is only necessary to it is inserted in casing and inserts
Enter fastener, meet nasal endoscopes patient's operating habit, based on above-mentioned, drainage general pipeline and drainage branch pipe are only moved at lower puncta
State is fixed, and foreign at endocanthion, patient perceptions are comfortable, no Accessory injury, and drainage tube is designed to hollow shape, can normal drainage tear
Liquid, not easy infection, remission is obvious during implantation, and can also pass through bubble pockets auxiliary when irrigation of lacrimal passage and carry out
It rinses.
