In the utility model, the locating effect is good, the device can not move owning to gravity, muscular contraction and the like, friction of the device and eyeballs is avoided, granulation tissue hyperplasia can be effectively prevented, the drainage effect is good, the length can be regulated conveniently, the price is low, the processing is convenient and the ductility is good.
Description
Technical field
This utility model relates to a kind of medical apparatus, relates in particular to the guiding device of eye-eye-nose communication tear.
Background technology
The extremely atrophy of dacryocystorhinostomy operative failure, lachrymal sac, lachrymal sac are extractd, wound causes the heavy damage of lachrymal sac structure, congenital lachrymal sac dysplasia or lack as patient, need between conjunctiva and nasal cavity, artificial tear duct be installed, the tear of lacrimal secretion be arranged to nasal cavity by artificial tear duct.At present, general artificial tear duct is the straight pipe structure of glass material, and existing deficiency is:
1, the locating effect of artificial tear duct is relatively poor, because of reasons such as gravity, muscle contraction, easily is moved.
2, the eyeball that rubs easily causes scratch, excites granulation tissue hyperplasia, causes drainage effect not good enough.
3, length is uncontrollable, and general long partially, and one little section meeting of artificial tear duct lower end is stayed in nasal cavity on the one hand, causes patient's foreign body sensation strong, and comfortableness is relatively poor; On the other hand, easily expose outside the eyelid upper end of artificial tear duct, can influence the outward appearance of patient's eyes.
4, cost an arm and a leg, unit price is 5000-6000 yuan, and patient bears difficulty.
5, no ductility causes profiles such as eyelid to change easily.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of locating effect well, the guiding device that is used for eye-eye-nose communication tear that can not be moved.
The technical solution of the utility model is as follows: a kind of guiding device that is used for eye-eye-nose communication tear, constitute by body and pipe cap, lower end at body is provided with disk body, the upper end of body is sleeved on the lower end of pipe cap, the upper end of described pipe cap is uncovered, and the upper port of pipe cap is the closing in structure, and the opposite side of this pipe cap upper port stretches out dorsad, forms a pair of location flange.
This utility model is installed between conjunctiva and the nasal cavity, and when the guiding tear flowed to nasal cavity, the location was good between body and the pipe cap, can not relatively move; The location flange of the disk body of body lower end and pipe cap upper end all plays a part spacing, even influenced by gravity, muscle contraction etc., this utility model can not move up or down yet.In addition, the location flange can also prevent that granulation from growing in the pipe cap, to ensure the unobstructed property of drain.
Described body and pipe cap are made by the plastic type material, and the cost of material is low like this, and processing and fabricating is easy, surplus unit price only needs 1000 yuan; The upper end of body is inserted in by the lower port of pipe cap, is evenly distributed with a plurality of first annular boss on the circumference on body top from top to bottom, is formed with the projection that matches with first annular boss on the inwall of described pipe cap lower end.The lower port of pipe cap is inserted in after the upper end of body, and the closing in restriction body of pipe cap upper end prevents the body play that makes progress; The bottom of one of them first annular boss of body top just in time fits with the projection of pipe cap lower end inwall, and this first annular boss is limited by projection, can prevent the downward play of body, and effective like this having avoided relatively moves between body and the pipe cap.Simultaneously, in the process of operation, the length required according to reality can be blocked the redundance of body upper end with scalpel, and is both convenient and swift, eliminated the foreign body sensation of patient's nasal cavity again, guaranteed the outward appearance of patient's eyes.
Described body is sleeved on by being threaded between pipe cap, connects firm, easy accessibility between the two, and relative displacement can not take place.
The diameter of described body bottom is evenly distributed with a plurality of second annular boss from top to bottom more than or equal to its upper part diameter on the circumference of body bottom.Second annular boss works to increase friction, with auxiliary body and pipe cap location, prevents that body and pipe cap from moving.
On the circumference of described body bottom, be evenly distributed with little convex closure.Little convex closure also plays a part to increase friction, assist location, has further guaranteed the steadiness that body and pipe cap are installed.
In order to improve drainage effect, the reduce friction chance of eyeball, by the first concave arc limit and the second concave arc edge transition, described first, second concave arc limit is all towards the direction bending of pipe cap axial line, and the minimum point on the second concave arc limit is higher than the minimum point on the first concave arc limit between the flange of a pair of location.
The beneficial effects of the utility model are:
1, locating effect is good, can not be moved because of reasons such as gravity, muscle contraction.
2, can avoid rubbing with eyeball, and effectively prevent granulation tissue hyperplasia, drainage effect is good.
3, length can be regulated as required, has eliminated the foreign body sensation of patient's nasal cavity, has reduced to be exposed to the outer chance of eyelid.
4, easy to process, low price only needs about 1000 yuan, and patient is easy to bear.
5, ductility is good, can prevent that profiles such as eyelid from changing.
