Description
technical field
This utility model relates to ophthalmology conventional operating equipment, particularly a kind of Lacrimal passage irrigator.
Background technology
Current, irrigation of lacrimal passage technology is the conventional means of diagnoses and treatment lacrimal passage disease, and from lower puncta water filling, the position judgement of flowing out from water has position clog-free and that block, and the character judgement of current has or not lacrimal apparatus inflammation.Yet in hospital, multi injector syringe needle is made (as shown in Figure 1), grinds off needle point with 5ml empty needle, needle body is held into certain camber, and irrigation of lacrimal passage is carried out in sterilization repeatedly.
Traditional Lacrimal passage irrigation syringe, meets puncta obturation or narrow person, also needs puncta dilator to expand, then carries out irrigation of lacrimal passage.Postoperative at lacrimal Laser, due to early stage lacrimal passage mucosal tissue edema, when doing irrigation of lacrimal passage with anti-inflammatory medicaments, resistance is larger, tradition Lacrimal passage irrigation syringe is because needle tubing diameter is thin, flow is low, cause flushing pressure inadequate, cause and can not rinse unobstructedly, medicine can not well act on lacrimal passage mucosal tissue.Because syringe needle is elbow, the entire length of elbow needle tubing is too short, can not well stretch into lacrimal passage, in the process of irrigation of lacrimal passage diagnosis lacrimal passage disease, can accurately not distinguish the position of obstructed lacrimal passage, for further therapeutic scheme brings difficulty.Therefore at the traditional Lacrimal passage irrigation syringe of the postoperative use of lacrimal Laser, usually rinse effect undesirable.
Utility model content
The purpose of this utility model is to overcome existing deficiency in prior art, and a kind of puncta dilator and straight Lacrimal passage irrigator of syringe needle of carrying is provided.
In order to realize above-mentioned utility model object, this utility model provides following technical scheme:
A Lacrimal passage irrigator, comprises syringe and Syringe needle Irrigator, and described syringe is comprised of syringe, push rod and needle stand, and described Syringe needle Irrigator is straight peen draw point, and the front end sleeve of described Syringe needle Irrigator has puncta dilator.
In above-mentioned Lacrimal passage irrigator, the front end of described straight peen draw point is blunt nosed smooth, prevents from damaging lacrimal passage.
In above-mentioned Lacrimal passage irrigator, described puncta dilator is tapered, the cecum that its front end is closed, and taper puncta dilator guarantees not damage patient when carrying out puncta expansion.
In above-mentioned Lacrimal passage irrigator, the material of described puncta dilator is rigid plastics.
In above-mentioned Lacrimal passage irrigator, the needle tubing diameter of described straight peen draw point is 0.8mm, and pressure when thicker needle tubing diameter can make to rinse is larger.
In above-mentioned Lacrimal passage irrigator, the needle tubing length of described straight peen draw point is 20mm, longer needle tubing length can directly stretch into the through lachrymal sac wall of lacrimal passage, can distinguish the particular location of obstructed lacrimal passage when irrigation of lacrimal passage, also syringe needle can be propped up if desired to the downward pressure flush of vertical 90 degree after lachrymal sac wall.
compared with prior art, the beneficial effects of the utility model:this utility model has puncta dilator at the front end sleeve of Syringe needle Irrigator, is applicable to the expansion of various punctas, and puncta dilator is tapered, and the cecum that its front end is closed guarantees not damage patient when carrying out puncta expansion.The more traditional syringe needle of Syringe needle Irrigator diameter is thick, and pressure during flushing is larger, can play the effect of pressure flush.Syringe needle Irrigator is straight peen draw point, and needle length is longer, can directly stretch into the through lachrymal sac wall of lacrimal passage, can distinguish the particular location of obstructed lacrimal passage when irrigation of lacrimal passage, also syringe needle can be propped up if desired to the downward pressure flush of vertical 90 degree after lachrymal sac wall.By this utility model, irrigation of lacrimal passage can better be used for to diagnostic techniques and the Therapeutic Method of lacrimal passage.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
In order to make object, technical scheme and the advantage of utility model clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, and be not used in restriction this utility model.
embodiment 1
As shown in accompanying drawing 2, accompanying drawing 3, the Lacrimal passage irrigator of the present embodiment, comprise syringe 1 and Syringe needle Irrigator 2, described syringe 1 is comprised of syringe, push rod and needle stand, described Syringe needle Irrigator 2 is straight peen draw point, the front end sleeve of described Syringe needle Irrigator 2 has puncta dilator 3, and the needle tubing diameter of described straight peen draw point is 0.8mm, and the needle tubing length of straight peen draw point is 20mm.
The use procedure of the present embodiment:
(1) the present embodiment, with puncta dilator 3, is applicable to the expansion of various punctas.During use, patient takes dorsal position, with after times promise happiness topical anesthesia, the puncta dilator 3 expansion punctas that first carry with the present embodiment, then puncta dilator 3 is taken off, again Syringe needle Irrigator 2 is stretched into irrigation of lacrimal passage lacrimal passage, in the process of rinsing, probes into forward, with the position of detecting obstructed lacrimal passage at lacrimal ductule, tear house steward or nasolacrimal duct.
(2) the more traditional syringe needle of Syringe needle Irrigator 2 diameter of the present embodiment is thick, and pressure during flushing is larger, can play the effect of pressure flush.Running into neonatal dacryocystitis needs pressure flush, utilizes the syringe needle diameter that the present embodiment is thicker to carry out pressure flush, can play good effect.
(3) Syringe needle Irrigator 2 is straight peen draw point, and needle length is longer, can directly stretch into the through lachrymal sac wall of lacrimal passage.In the face of lacrimal Laser postoperative patient, if syringe needle stretches into lacrimal ductule, can not rinse unobstructedly, can prop up after lachrymal sac wall the downward pressure flush of vertical 90 degree again, anti-inflammatory type eye hydroful can be distributed in to lacrimal passage tube wall, play the object that alleviates tube wall edema.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
