Description
Technical field
The present invention relates to the field of medical instrument technology, specially a kind of stacked casing for dacryocystorhinostomy and its
Preparation method.
Background technology
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 adhesion at pore-creating it is narrow in addition locking, lead 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 reaches 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 and lachrymal sac wall, needs upper and lower puncta simultaneously
Implantation, may cause the complication such as shearing splitting puncta, endocanthion to have 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.
Invention content
In order to overcome the shortcomings of that prior art, the present invention provide a kind of stacked casing for dacryocystorhinostomy

Cross the air ring being fixed on internal surface of sleeve pipe.
In addition, the present invention also provides a kind of preparation method being stacked casing for dacryocystorhinostomy, including it is as follows
Step：
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 manifold, and axis fixed installation is drawn centered on the hollow microporous to drain the both ends manifold
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；
Step 300, drainage tube heated under the conditions of 50-60 DEG C according to shape need it is moulding, it is naturally cold after thermoplastic solid
But, it and carries out disinfection spare.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is implanted into convenient, it is only necessary to be drawn by the implantation of lower puncta
It flows at manifold and the i.e. reachable pore-creating of drainage branch pipe, is matched with clinically widely used lacrimal probe, it need not be additional
Draft gear, take only several minutes, and in nasal cavity without knot etc. complex process, it is only necessary to be inserted in casing be inserted into fastener i.e.
Can, meet nasal endoscopes patient's operating habit, based on above-mentioned, drainage manifold and drainage branch pipe dynamic only at lower puncta are fixed,
Foreign at endocanthion, patient perceptions are comfortable, no Accessory injury, and drainage tube is designed to hollow shape, can normal drainage tear, be not easy
Infection, remission is apparent during implantation, and can also be assisted being rinsed by bubble pockets when irrigation of lacrimal passage.

Upper widely used lacrimal probe matches, and does not need additional draft gear, takes only several minutes, is grasped convenient for clinician
The pain of patient can also be mitigated while work.
It and further, can be to avoid at the complexity of nose Endoscopic Knotting by the connection type of casing 7 and fastener 6
Reason, only need to by be inserted in casing 5 can composite thin shell endoscopists operating habit.
As preferred embodiment, the shape of the drainage manifold 1 and the connector shape size and lacrimal passage that drain branch pipe 2
Shape size is identical, and drains manifold 1 and be located on the inside of nasal cavity, described sleeve pipe 7 in rounding mesa-shaped, and casing 7 and fastener 6 it
Between pass through the air ring 8 that is fixed on 7 inner wall of casing.
The dynamic that above-mentioned drainage manifold 1 and drainage branch pipe 2 is only limitted at lower puncta is fixed, and drains 1 Hes of manifold
The overall structure that drainage branch pipe 2 is formed meets human body lacrimal passage anatomical physiology structure, foreign at endocanthion, and patient perceptions are comfortable, nothing
Accessory injury.
In addition, as a preferred technical solution of the present invention, as shown in Fig. 2, additionally providing a kind of for lachrymal sac nasal cavity
Anastomosis is stacked the preparation method of casing, includes the 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 manifold, and axis fixed installation is drawn centered on the hollow microporous to drain the both ends manifold
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；
Step 300, drainage tube heated under the conditions of 50-60 DEG C according to shape need it is moulding, it is naturally cold after thermoplastic solid
But, it and carries out disinfection spare.
In the present embodiment, additionally provide and application method, it is specific as follows shown in：
First, open lower puncta, drainage manifold and drainage branch pipe be implanted by lacrimal probe, and make drainage manifold and
Branch pipe is drained to reach at pore-creating；
Secondly, the position of adjustment drainage manifold and drainage branch pipe so that oval drainage disc is bonded lachrymal sac inner wall；
