Description
Technical field
The utility model belongs to medical instruments field, is that one kind is applied in ophthalmologic operation and plays lacrimal passage again specifically
The drainage tube of logical effect.
Background technology
Lacrimal passage blocking is a kind of common ophthalmological disorder, including up/down obstruction of lacrimal canaliculus, tear duct obstruction, obstruction of naso lacrimal duct
Deng being often happened at puncta, lacrimal, lachrymal sac/nasolacrimal duct intersection.Lacrimal passage blocking can make patient shed tears for a long time, seriously affect
Daily life.
Currently, clinically mostly use lacrimal passage to lead to technology again blocks progress operative treatment, such as Chinese patent text to lacrimal passage
It offers CN 204306954U and CN 104066405A and discloses a kind of lacrimal passage of nunchakus type siphunculus again, pass through two lacrimal passages
Drainage catheter is inserted into up/down lacrimal passage and solves topic of corresponding again respectively.But the lacrimal passage of above structure again siphunculus use exist it is as follows
Problem：It needs two probing of lacrimal passage conduits being inserted into the up/down lacrimal passage regular hours in the process due to again leading to, at this time up/down
In lacrimal passage may because of material allergy, indwelling time be too long etc., reasons cause compromised internal inflammation, at this time according to common hand
Section, needs to lead two probing of lacrimal passage and release from up/down lacrimal passage, then by liquid such as the antiphlogistics, brine, antibiotic of anti-inflammatory
It injects in up/down lacrimal passage, then two probing of lacrimal passage conduits is reinserted in up/down lacrimal passage again, it is this due to stenosis of lacrimal passage
Method is not only troublesome, the extended treatment time, can also increase the pain of patient, it is difficult to be used widely in a practical situation.
Invention content
For lacrimal passage exists in the prior art, treatment time existing for siphunculus is long again, is easy to bring asking for pain to patient
Topic, the utility model provides one kind also can quickly treat inflammation problem in up/down lacrimal passage without extracting probing of lacrimal passage conduit
Lacrimal passage to mitigate patient's pain leads to drainage tube again.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
It includes that logical drainage tube and lower lacrimal passage lead to drainage tube to upper lacrimal passage again again, and the upper lacrimal passage leads to drainage tube and lower lacrimal passage again
The end for leading to drainage tube again is connected to by connecting tube, and upper lacrimal passage leads to drainage tube and lower lacrimal passage and leads to again in the tube wall of drainage tube again to be inserted with
Bougie, the end of bougie are equipped with handle, at least provided with a liquid-entering hole in the connecting tube, the upper lacrimal passage lead to again drainage tube and
The front end that lower lacrimal passage leads to drainage tube again is respectively equipped with fluid hole, and upper lacrimal passage leads to the week that drainage tube and lower lacrimal passage lead to drainage tube again again
If side, which is provided with, does liquid aperture.
Using above-mentioned technical proposal lacrimal passage again lead to drainage tube, in use, can according to normal method by upper lacrimal passage again
Logical drainage tube and lower lacrimal passage lead to drainage tube and are inserted into lacrimal passage and lower lacrimal passage respectively again, if there is sense in upper lacrimal passage and lower lacrimal passage
The problems such as hair dyeing is scorching at this time only needs to inject the liquids such as sterile saline or antibiotic from liquid-entering hole, these liquids
Leading to drainage tube and lower lacrimal passage again from upper lacrimal passage, the fluid hole of logical drainage tube front end and the liquid aperture that goes out of side are discharged again, to directly
It acts at the infection in lacrimal passage and lower lacrimal passage, avoids the need for first extracting lacrimal passage and lead to drainage tube again and carry out liquid injection again
Problem can shorten treatment time, mitigate the pain of patient.
It further limits, it is the blunt nosed shape of circular cone that the upper lacrimal passage leads to drainage tube and lower lacrimal passage and leads to the front end of drainage tube again again.
Front end is arranged to the blunt nosed shape of circular cone can both can smoothly enter into order to guide upper lacrimal passage to lead to drainage tube and lower lacrimal passage again and lead to drainage tube again
In up/down lacrimal passage, additionally it is possible to lacrimal passage be avoided to lead to the spiny structure pair in front end that drainage tube and lower lacrimal passage lead to drainage tube again again
Up/down lacrimal passage causes to damage.
It further limits, the upper lacrimal passage leads to drainage tube and lower lacrimal passage and leads to again on drainage tube again is respectively equipped with corresponding scale
Value.Lead to drainage tube and lower lacrimal passage again in upper lacrimal passage and lead to setting scale value on drainage tube again and is conducive to the observation of medical staff's accurate and effective
Upper lacrimal passage leads to drainage tube and lower lacrimal passage and leads to the length that drainage tube is inserted into up/down lacrimal passage again again, avoids the occurrence of and is inserted into too deep or is inserted into
Inadequate problem.
It further limits, there are two the liquid-entering holes, is separately positioned on connecting tube and leads to drainage tube and lower tear again with upper lacrimal passage
Road leads to the junction of drainage tube again.Above-mentioned restriction is that liquid enters upper lacrimal passage and leads to drainage tube and lower lacrimal passage again and lead to again and draws for convenience
In flow tube, to make liquid snap action at the infection of up/down lacrimal passage.
It further limits, it is 40mm that the upper lacrimal passage leads to drainage tube and lower lacrimal passage and leads to the length of drainage tube again again, connection
Length of tube is 8mm.
For the utility model since liquid-entering hole being arranged in connecting tube, lacrimal passage, which leads to again on drainage tube, over/under is set into out liquid
Hole and go out liquid aperture, this is conducive to when lacrimal passage over/under leads to drainage tube indwelling in lacrimal passage again directly entering from connecting tube
Fluid apertures notes people's liquid, then leads to fluid hole on drainage tube again by up/down lacrimal passage and goes out liquid aperture discharge liquid, to avoid out
It now needs to extract and leads to the process that drainage tube carries out liquid injection again again, shorten treatment time, alleviate the pain of patient.
Description of the drawings
Fig. 1 is the structural schematic diagram that the utility model lacrimal passage leads to drainage tube again；
Fig. 2 is the construction definition graph anatomically of up/down lacrimal passage；
Corresponding mark is respectively in figure：The upper lacrimal passages of 1- lead to drainage tube, 11- fluid holes again, and 12- goes out liquid aperture, lacrimal passage under 2-
Lead to drainage tube again, 3- connecting tubes, 31- liquid-entering holes, 4- bougies, handle after 41-, 5- scale values, the upper lacrimal passages of 6-, lacrimal passage under 7-.
Specific implementation mode
