Abstract
The utility model provides an open form provides an in same direction as inserting formula tear way expansion strip, has long and thin round strip, and it is protruding that its characterized in that, this tear say that the middle part of expansion strip has the several diameter to be greater than sphere or the spheroidicity of expanding strip body diameter. It is protruding that this tear says that expansion strip both ends respectively have the several diameter to be greater than sphere or the spheroidicity of expanding strip body diameter. Should state tear and say that two ends of expansion strip slightly were coniformly. The utility model discloses an in same direction as inserting formula tear way expansion strip, simple structure, the processing ease, the fixity is good, and the curative effect is reliable, does not harm normal tear way, does not influence people's eye outward appearance, takes out the convenience, is favorable to popularizing and applying. Sphere or spheroidicity have swollen for barb greatly reduced the stimulation that tear was said. Two ends slightly are coniform also tear and say that the expansion strip has reduced the stimulation of saying to tear when inserting the tear way.
Description
Technical field
This utility model belongs to the tear duct dilating bar of control obstructed lacrimal passage.
Background technology
Modern medicine focuses on Minimally Invasive Surgery day by day, especially the simple effectively therapy of No operation.The obstructed lacrimal passage caused by a variety of causes belongs to ophthalmology common frdquently encountered disease, accounts for ophthalmology outpatient's 1/10 ~ 1/5, at present such illness many employings lacrimal passage intubation art for the treatment of, but retrograde catheterization is more difficult from nasal cavity operation, and conduit easily comes off.
The conduit that general direct motion intubate uses or human body is stimulated and Lacrimal path damage and can not being long placed in because of material, or can not drain because conduit very easily blocks, or fix bad being easy to because of conduit and come off, or dilatancy is poor because of hollow tubing conductor easy compressive deformation, maybe can not solve the problems such as lacrimal passage epimere and full obstructed lacrimal passage, all make intubation clinical practice be extremely restricted.Dacryocystorhinostomy complicated operation, patient is painful and can only solve lacrimal passage hypomere obstructing problem.Great saphenous vein transplantation is except to except human body wound, and curative effect is also imprecise.Special installation and equipment is needed as the therapy such as air bag expansion, lacrimal stent, expensive, be difficult to promote.
Chinese patent Authorization Notice No. CN202446653U, this utility model relates to the full lacrimal passage expansion line of a kind of ophthalmic medical instrument.Adopt the disposable cast molding of nylon material, point draught line, lacrimal ductule expansion path and lachrymal sac and nasolacrimal duct expansion path three part, after draught line, taper is thicker at twice.Coordinate lacrimal probe for irrigation, lacrimal passage pull wire to import lacrimal passage and implement full tear duct dilating and drug treatment.This patent does not solve caducous technical problem yet.
Chinese patent Authorization Notice No. CN204306933U discloses a kind of lacrimal stent, and nasolacrimal duct body is provided with agnail, and down, agnail is wedge-like, taper, column, strip or thorn-like in agnail direction; This agnail also can be larger to the stimulation of lacrimal passage.
Summary of the invention
The technical problems to be solved in the utility model is to provide the positive inserted tear duct dilating bar of the simple and effective control obstructed lacrimal passage of a kind of energy and difficult drop-off.
The technical solution of the utility model is:
A kind of positive inserted tear duct dilating bar, has elongated round strip, it is characterized in that, the middle part of this tear duct dilating bar has several diameter to be greater than the spherical or elliposoidal projection of expansion bar body diameter.
Further, above-mentioned tear duct dilating bar upper and lower part respectively has several diameter to be greater than the spherical or elliposoidal projection of expansion bar body diameter.
Further, the spherical or elliposoidal projection at above-mentioned middle part is 2.
Further, each 1 of above-mentioned spherical or elliposoidal projection upper and lower part.
Further, above-mentioned body long 60 ~ 80mm, diameter 0.8mm, the spherical or elliposoidal protrusion diameter 1.2mm in described middle part, described tear duct dilating bar two ends are far from the spherical of 15mm place, middle part or elliposoidal protrusion diameter 1.0mm.
Further, above-mentioned tear duct dilating bar two end is slightly in coniform.
Further, above-mentioned tear duct dilating bar is medical silica-gel preparation.
Positive inserted tear duct dilating bar of the present utility model, structure is simple, processing ease, and stationarity is good, and curative effect is reliable, does not damage normal lacrimal passage, does not affect human eye outward appearance, convenient to remove, is conducive to applying.
Spherical or elliposoidal projection greatly reduces the stimulation of lacrimal passage relative to agnail.
Two ends slightly reduce the stimulation to lacrimal passage when inserting lacrimal passage in coniform also tear duct dilating bar.
Accompanying drawing explanation
The structural representation of Fig. 1 to be this utility model be positive inserted tear duct dilating bar.
Accompanying drawing is masked as: 1-tear duct dilating bar body; 2-holds spherical or elliposoidal projection; The coniform end of 3-.
detailed description of the invention
In this utility model, the noun of locality such as " upper and lower, left and right " of use typically refers to reference to upper and lower, left and right shown in the drawings; " inside and outside " refers to profile inside and outside relative to each parts itself.
Be further described below in conjunction with accompanying drawing:
See accompanying drawing 1, the tear duct dilating bar body 1 of elongated round strip is divided into upper and lower from intermediate point, and middle part and upper and lower two can have several diameter comparatively to expand the large spherical or elliposoidal projection 2 of bar body diameter; Middle part projection 2 that is spherical or elliposoidal can be 2, the spherical or elliposoidal projection 2 of upper and lower two can be each 1, tear duct dilating bar body 1 two ends be coniform end 3.
Preferably, for preventing expanding bar slippage, being convenient to direct motion insertion and having the effect better expanding lacrimal passage, following parameters can be adopted: tear duct dilating bar is about 60 ~ 80mm, diameter 0.8mm, in the middle part of expansion bar, diameter that is spherical or elliposoidal projection 2 is about 1.2mm, and spherical or elliposoidal projection 2 diameter at expansion about 15mm place far from middle part, bar two ends is about 1.0mm; Expansion bar two end is slightly in coniform.
This positive inserted tear duct dilating bar can adopt the materials such as medical silica-gel to make.
Below do illustrating of a straight step in conjunction with example:
Patient lies supine, suffer from eye conjunctival sac table fiber crops 2 times, lignocaine 2mm makes anterior ethmoidal nerve and trochlear nerve local anaesthesia, lacrimal passage probing (note normal saline confirms) routinely, to enter from lower lacrimal point with 0.8 ~ 1.3mm lacrimal probe successively and expand lacrimal passage, take out probe, slowly expansion bar is brought into lacrimal passage near the end elongated for No. 5, dentistry syringe needle being inserted tear duct dilating bar (having sterilized for subsequent use) one end, again syringe needle is exited spherical or elliposoidal projection 2 place inserting expansion bar one end to enter one and downwards advance expansion bar until spherical or elliposoidal projection 2 arrives at lower lacrimal point place in the middle part of expansion bar.The bar other end will be expanded with same method again and insert lacrimal passage until nasal cavity from upper lacrimal point.Art finishes.Sub-conjunctival injection gentamycin and dexamethasone.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; this utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
