Abstract
The utility model discloses a lacrimal passage device, which comprises a tube body, and is characterized in that: the tube body comprises solid pipelines at the two ends inserted into a lacrimal passage, and a solid soft pipeline positioned between the solid pipelines at the two ends, wherein the side wall of the hollow soft pipeline which is exposed outside the lacrimal passage is provided with an injection hole; and the side wall of the hollow soft pipeline which is positioned in the lacrimal passage is provided with a liquid outlet hole. The lacrimal passage device has the beneficial effects that: 1, soft and hard parts are combined, and an integral design is adopted, so that the lacrimal passage device is easy to place and take out, small pain is caused, time and labor are saved, and operation is easy; 2, hollow and solid pipelines are combined, so that damages are reduced, and convenience is brought to flushing; and 3, the lacrimal passage device is consistent with the physiological structure and shape of the lacrimal passage.
Description
[technical field]
This utility model relates to medical apparatus and instruments, more specifically to a kind of lacrimal passage device that can be used for rebuilding lacrimal passage or repair the lacrimal passage wound.
[background technology]
The Lacrimal Passage Block that various inflammation, wound cause is the commonly encountered diseases of ophthalmology, with symptoms such as excessive tear and pyorrheas, brings great inconvenience and misery to the patient.
Lacrimal passage intubation is the method for the treatment Lacrimal Passage Block commonly used.At present the lacrimal passage intubation of usefulness is rigid dura mater outer tube or soft silica gel tube.The compatibility of lumbar anesthesia tubing is poor, and quality is hard, and irritation is obvious, easily causes patient's sense of discomfort, and easily causes tearing of puncta, even deviates from voluntarily, brings inconvenience to patient's life, can't Preserving time.Although the compatibility of soft silicon sebific duct is better, but the quality softness can't directly be implanted lacrimal passage, need to guide with tinsel and silk thread or dura mater outer tube more, this intubation procedure is not only time-consuming but also require great effort, not easy to operate, and the operation also usually cause puncta, lacrimal ductule, nasal cavity and pharyngeal equivalent damage, bring larger misery to the patient.
More than two kinds of common shortcomings of lacrimal passage intubation be, the band pipe during in can't irrigation of lacrimal passage.If irrigation of lacrimal passage needs inserting needle in the narrow slit between lacrimal passage wall and lacrimal passage intubation, Syringe needle Irrigator easily causes iatrogenic injury to the lacrimal passage wall, even forms iatrogenic obstructed lacrimal passage, causes the failure for the treatment of.
[utility model content]
The purpose of this utility model provides a kind of be easy to place and take out, be easy to irrigation of lacrimal passage, eutherapeutic lacrimal passage device.
For above-mentioned purpose, this utility model by the following technical solutions:
A kind of lacrimal passage device, include body, it is characterized in that described body includes the solid pipeline in two ends and the hollow hoses road between the solid pipeline in two ends that inserts in the lacrimal passage, the sidewall of described hollow hoses road outside exposing lacrimal passage is provided with injection orifice, and the sidewall that described hollow hoses road is positioned at lacrimal passage is provided with liquid outlet.
Aforesaid a kind of lacrimal passage device is characterized in that being provided with solid in the solid pipeline in described two ends, and described solid is metal material or ceramic material.
Aforesaid a kind of lacrimal passage device is characterized in that described liquid outlet is a plurality of, radially distributes along tube wall.
Aforesaid a kind of lacrimal passage device is characterized in that described hollow hoses road is arc.
Aforesaid a kind of lacrimal passage device, the end that it is characterized in that the solid pipeline in described two ends are round and smooth projected curved surface shape.
The beneficial effects of the utility model have: lacrimal passage device described in the utility model can be used for obstructed lacrimal passage disease such as chronic dacryocystitis, the fracture of obstructed lacrimal passage lacrimal ductule wound, also can be used for treating the stricture of lacrimal passage sexually transmitted disease (STD) and becomes, and it has the following advantages:
1. soft or hard combination, integrated design is easy to place and take out, and is painful little, time saving and energy saving easy operating.
2. hollow and solid combination reduces damage, is convenient to flushing.Avoided damage for the lacrimal passage wall from the side opening inserting needle, can wash from side opening, flushing liquor can flow out from the side opening that is arranged in lacrimal passage by side opening, for the obstructive position administration more directly effectively.To Lacrimal Passage Block, especially can wash with the Lacrimal Passage Block that infects, injection so support, prevent the better effects if of adhesion, has significant advantage than the tear channel pipe of prior art;
3. flexible pipe has two turnovers, meets lacrimal passage physiological structure and shape.First be up and down between the puncta and radian, second invayination that enters lachrymal sac for lacrimal ductule.
[description of drawings]
Fig. 1 is structural representation of the present utility model.
[specific embodiment]
As shown in Figure 1, a kind of lacrimal passage device of this utility model indication includes body 1, and described body 1 includes the solid pipeline 2 in two ends and the hollow hoses road 3 between the solid pipeline 2 in two ends that inserts in the eyes lacrimal passage, and described hollow hoses road 3 is arc.The sidewall of described hollow hoses road 3 outside exposing lacrimal passage is provided with injection orifice 4, and the sidewall that described hollow hoses road 3 is positioned at lacrimal passage is provided with liquid outlet 5.Described liquid outlet 5 is a plurality of, radially distributes along tube wall.
In this utility model, be provided with solid 6 in the solid pipeline 1 in described two ends, described solid 6 is metal material or ceramic material.Judge its position when being conducive to according to X-ray.The end of the solid pipeline 1 in described two ends is round and smooth projected curved surface shape.
This utility model in use, behind the probing of lacrimal passages, expansion is puncta up and down, lacrimal passage device solid section is inserted in the lachrymal sac from puncta up and down respectively, from the medium pore irrigation of lacrimal passage medicated pillow is inserted in the hole flushing liquors such as injection of medicine (such as tobramycin) or normal saline, inject flushing liquor, because the bottom is solid section, so flushing liquor is from all overflowing the flushing of finishing the lacrimal passage different parts from different side openings, flushing liquor is partly stayed and is played the lubricated effect of sterilization in the lacrimal passage simultaneously.
