Abstract
The invention relates to an expanding artificial duct for a nasolacrimal canal. The artificial tube comprises a tear guide duct, an expanding sac, a soluble plugging bolt and a pull wire, wherein the expanding sac is sleeved outside the tear guide duct; the soluble plugging bolt is arranged in the tear guide duct; the pull wire is arranged at the upper end of the tear guide duct; the upper end of the expanding sac is fixedly connected with the tear guide duct; the lower end of the expanding sac is fixedly connected with the tear guide duct through a ligature; the tear guide duct is communicated with the expanding sac through a water injection hole; and a valve sleeve is sleeved on the tear guide duct outside the water injection hole. The expanding artificial tube has the advantages of easy implantation into and extraction from the nasolacrimal canal, small trauma and good treatment effect.
Description
Technical field
The present invention relates to a kind of expanding nasolacrimal duct justice pipe.
Background technology
Present widely used nasolacrimal duct justice pipe complicated operation is difficult for entering nasolacrimal duct during implantation, bigger to nasolacrimal duct epithelium wound when implanting or taking out, and can not effectively expand nasolacrimal duct, and therapeutic effect is undesirable.
Summary of the invention
Technical problem to be solved by this invention provides a kind of being easy at nasolacrimal duct implantation and taking-up, wound is little, therapeutic effect is good expanding nasolacrimal duct justice pipe.
The present invention adopts following technical scheme:
The draught line that the present invention includes a tear duct, is sleeved on the outer expansion capsule of tear duct, is arranged on the solubility suppository for blocking in the tear duct and is arranged on the tear duct upper end, fixedly connected with tear duct in the upper end of described expansion capsule, described expansion capsule lower end adopts ligature to fixedly connected with tear duct, described tear duct is connected by water injection hole and expansion capsule, is set with valve sleeve on the tear duct outside water injection hole.
The present invention is provided with throttling ring in the lower end of tear duct.
Good effect of the present invention is as follows:
Use the present invention, simple to operate, the present invention is provided with the expansion capsule, to expand the capsule dilation by water injection after the present invention is implanted to nasolacrimal duct, can effectively expand nasolacrimal duct after the water filling of expansion capsule, and make tear duct in official hour, be fixed in the nasolacrimal duct effectively, strengthened curative effect, nasolacrimal duct is unobstructed after treating, and can emit the liquid in the expansion capsule when taking-up is of the present invention from nasolacrimal duct, and volume was all less when the present invention implanted from nasolacrimal duct or takes out like this, so be easy to implant and take out at nasolacrimal duct, wound is little, uses when of the present invention in order to observe the shape of adopted pipe, position and degrees of expansion can be injected contrast agent in the expansion capsule.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is sectional structure sketch map of the present invention;
Accompanying drawing 3 is expanded structural representation behind the capsule water-filling for the present invention;
Accompanying drawing 4 is expanded sectional structure sketch map behind the capsule water-filling for the present invention.
In the accompanying drawings, 1 tear duct, 2 ligatures, 3 throttling rings, 4 expansion capsules, 5 draught lines, 6 water injection holes, 7 solubility suppository for blocking, 8 valve sleeves.
The specific embodiment
Be depicted as a specific embodiment of the present invention as accompanying drawing 1,2,3, the present invention includes a tear duct 1, be sleeved on the outer expansion capsule 4 of tear duct 1, be arranged on solubility suppository for blocking 7 in the tear duct 1 and the draught line 5 that is arranged on tear duct 1 upper end, fixedly connected with tear duct 1 in the upper end of described expansion capsule 4, described expansion capsule 4 lower ends adopt ligature 2 to fixedly connected with tear duct 1, described tear duct 1 is connected by water injection hole 6 and expansion capsule 4, is set with valve sleeve 8 on the tear duct 1 outside water injection hole 6.The present invention is provided with throttling ring 3 at an end of tear duct 1.
Use the present invention to expand nasolacrimal duct justice pipe operating procedure following (not as a limitation of the invention):
(1) at first does trochlear nerve and block anesthesia of infraorbital nerve, the nasal mucosa cotton sheet topical anesthesia of tetracaine adnephrin;
(2) visit logical lacrimal passage with hollow lacrimal probe and wash unobstructedly, described hollow lacrimal probe adopts the transformation of the way of lumbar anesthesia piercing needle to form (be about to lumbar anesthesia piercing needle needle point polish get final product);
(3) seal wire is inserted in the nasal meatus from hollow lacrimal probe upper end, and with seal wire traction to the nostril, it is the nylon wire of 0.1～0.4mm that described seal wire can adopt diameter, adopt 1 milliliter of syringe to inhale normal saline or contrast agent, syringe is connect No. 6 bareheaded pins (being about to needle point polishes), connect tight tear duct 1 lower end after draining air;
(4) draught line 5 of tear duct 1 upper end is connected with seal wire outside being positioned at the nostril, at the upper end of hollow lacrimal probe traction seal wire, seal wire pulling draught line 5, move up along nasal cavity, nasolacrimal duct from bottom to top by the whole tear duct 1 of draught line 5 pullings, after the lower end of the upper end of tear duct 1 and hollow lacrimal probe contacts, under the pulling function of seal wire and draught line 5, tear duct 1 and hollow lacrimal probe upwards move in nasolacrimal duct simultaneously, when throttling ring 3 moves to the nasolacrimal duct collar extension, this moment, pulling was obstructed, and stopped to draw seal wire;
(5) adopt syringe to push contrast agent or normal saline to the tear duct 1 that is positioned at nasolacrimal duct, enter normal saline in the tear duct 1 or contrast agent under the prevention of solubility suppository for blocking 7, can only pass through water injection hole 6 under pressure, valve sleeve 8 enters in the expansion capsule 4, expansion capsule 4 is expanded reach the purpose of expansion nasolacrimal duct, valve sleeve 8 of the present invention adopts rubber finger sleeve, make liquid can only pass through water injection hole 6, valve sleeve 8 enters in the expansion capsule 4, and can not flow out outside the expansion capsule 4 by water injection hole 6, pull up the water filling syringe needle that the tear duct lower end connects, take off syringe, pull up hollow lacrimal probe from lacrimal point, to expose a side of the draught line 5 of lacrimal point and cut off, and draught line 5 will be removed from tear duct 1;
(6) annotate normal saline with Syringe needle Irrigator in lacrimal passage, be interrupted the flushing lacrimal passage, the solubility suppository for blocking 7 that is positioned at tear duct 1 is dissolved until unobstructed lacrimal passage, described solubility suppository for blocking 7 adopts the sucrose or the glucose of meeting water-solubleization to make;
When (7) two weeks, the present invention's justice pipe was taken out in the back, unclamp tear duct 1 lower end ligature 2 earlier, the liquid in the expansion capsule 4 flows out from the gap between tear duct 1 and the expansion capsule 4, emits in the expansion capsule 4 and tear duct 1 is pulled out from nasolacrimal duct, nasal cavity behind the liquid again.
