Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of apparatus for the treatment of ophthalmology lacrimal passage disease, particularly a kind of obstructed lacrimal passage that a variety of causes causes and full lacrimal passage silica gel drainage tube of stricture of lacrimal passage for the treatment of.
Background technology
Obstructed lacrimal passage is a kind of commonly encountered diseases of ophthalmology, comprises upper and lower obstruction of lacrimal canaliculus, the total pipe choking of tear, obstruction of naso lacrimal duct or narrow.Obstructed lacrimal passage stays the storage of lachrymal sac content, makes bacteria breed, and severe one causes acute and chronic suppurative dacryocystisis, corneal ulcer etc.This disease adopts surgical operation or lacrimal passage intubation treatment conventionally at present, but all drawbacks of various degrees of two kinds of methods: surgical operation therapy has improved curative effect, but complicated operation, and facial area residual cicatrix etc. again, and lacrimal ductule, quite difficulty of the total pipe choking operation of tear.The main utensil of lacrimal passage intubation treatment is that two harder rustless steel probe both ends connect one section of silica gel tube; silica gel tube is fixed on the lacrimal passage intubation art of carrying out on probe; usually can run into insert difficulty, puncta tears, hook probe from nasal cavity easily causes the complication such as nasal bleeding, and the silica gel tube of indwelling is easily come off.
Summary of the invention
This utility model is to solve the problems referred to above that prior art exists, and a kind of full lacrimal passage silica gel drainage tube is provided, and intubate is convenient, be difficult for deviating from, and supports, prevents the effective of adhesion, can expand narrow lacrimal passage, and have good histocompatibility.
The purpose of this utility model is achieved through the following technical solutions:
A kind of full lacrimal passage silica gel drainage tube, comprise: indwelling tube, it is characterized in that, described indwelling tube is the silica gel tube of hollow, one section of solid convergent divergent channel of the each connection in two ends of described indwelling tube, the end of described convergent divergent channel is taper, and the convergent divergent channel taper end at described indwelling tube two ends is all connected with lead-in wire, and described lead-in wire inserts convergent divergent channel and runs through whole convergent divergent channel.
Improvement to technique scheme: the maximum outside diameter of described convergent divergent channel is slightly larger than the external diameter of indwelling tube, and the joint portion of convergent divergent channel and indwelling tube is rounding off.
Further improvement to technique scheme: described convergent divergent channel is silica gel tube, described convergent divergent channel and indwelling tube are one-time formed integrative-structure.
Further improvement to technique scheme: the outer surface of described convergent divergent channel and indwelling tube joint portion arranges fracture trace line.
Further improvement to technique scheme: described lead-in wire is polypropylene or nylon lead-in wire, and the total length that described lead-in wire exposes outside convergent divergent channel is 100mm.
Further improvement to technique scheme: the external diameter of described indwelling tube is that 0.8mm, internal diameter are that 0.6mm, length are 100-120mm; The external diameter of the convergent divergent channel at described indwelling tube two ends is 1.0mm, length and is respectively 50-55mm.
This utility model compared with prior art has the following advantages and good effect:
This utility model is applicable to tear little (always) pipe, obstruction of naso lacrimal duct and tear little (always) and manages narrowly, and dacryocystorhinostomy and stenosis of naso lacrimal duct sexually transmitted disease (STD) become.The full lacrimal passage silica gel of this utility model drainage tube is difficult for damage eye in the time of operation, runs through the lead-in wire of convergent divergent channel and the taper end of convergent divergent channel and has ensured that drainage tube enters smoothly tear stains and do not rupture, and is difficult for causing damage.The setting of fracture trace line is cut off and split extension pipe after being convenient to indwelling tube and putting in place, guarantees good operation effect, and postoperative appearance looks elegant.Intubate is convenient, drainage pipe is difficult for deviating from, and can expand narrow lacrimal passage, and histocompatibility is good, supports, prevents that the effect of adhesion is good.Drainage tube is simple in structure, and cost of manufacture is lower, is easy to universal and applies.

Detailed description of the invention
Referring to Fig. 1, the embodiment of a kind of full lacrimal passage drainage tubes of this utility model, the silica gel tube that middle indwelling tube 1 is hollow, at one section of solid convergent divergent channel 2 of the each connection in the two ends of indwelling tube 1, the end of described convergent divergent channel 2 is taper, the convergent divergent channel 2 taper ends at described indwelling tube 1 two ends are all connected with lead-in wire 3, and described lead-in wire 3 inserts convergent divergent channel 2 and runs through whole convergent divergent channel 2.
The maximum outside diameter of convergent divergent channel 2 is slightly larger than the external diameter of indwelling tube 1, and convergent divergent channel 2 is rounding off with the joint portion of indwelling tube 1, after putting in place for the ease of indwelling tube 1, cut off and split extension pipe 2, at convergent divergent channel 2 and the outer surface of indwelling tube 1 joint portion, fracture trace line 4 is set.
In actual use, conventional specification is: the external diameter of indwelling tube 1 is that 0.8mm, internal diameter are that 0.6mm, length are 100-120mm, and the external diameter of the convergent divergent channel 2 at indwelling tube 1 two ends is 1.0mm, length and is respectively 50-55mm., lead-in wire 3 total lengths that expose outside convergent divergent channel 2 are 100mm.
Convergent divergent channel 2 is solid silicon sebific duct, and convergent divergent channel 2 and indwelling tube 1 are one-time formed integrative-structure; Lead-in wire 3 is for polypropylene or nylon lead-in wire and in the time that molding is manufactured, implant convergent divergent channel 2.Due to being smoothly connected of polypropylene or nylon lead-in wire 3 and convergent divergent channel 2, full lacrimal passage drainage tubes can slip into lacrimal passage like a cork, then draws from nasal cavity.
When obstructed lacrimal passage or the operation of narrow row Lacrimal passage tube, after the probe dredging lacrimal passage with memory guide wire, lead-in wire 3 drives in the wrong direction or slowly introduces lacrimal passage from lacrimal point direct motion from nasal cavity, convergent divergent channel 2 slips into lacrimal passage gradually, convergent divergent channel 2 is blocking in narrow lacrimal passage after fully expansion, convergent divergent channel 2 is drawn to lacrimal passage, indwelling tube 1 enters lacrimal passage smoothly, lead-in wire 3 and the convergent divergent channel 2 of one end are stayed outside lacrimal passage, lead-in wire 3 and the convergent divergent channel 2 of the other end are drawn from lacrimal point or nasal cavity then, tailing edge fracture trace line 4 places cut off and with convergent divergent channel 2 with go between and 3 separate, indwelling tube 1 indwelling in lacrimal passage, nasal cavity knotting is fixing, complete operation.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and this utility model is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, variation, remodeling, interpolation or the replacement done, also should belong to protection domain of the present utility model.
