Abstract
The utility model provides a kind of lacrimal point forming device of ophtalmic treatments punctal stenosis, which is characterized in that including hollow body, the outside of hollow body is equipped with first annular fixed structure and the second annular anchoring structures for blocking the ampulla of puncta.The utility model complies fully with puncta physiology and anatomic form, is easily placed, and is not easy after implantation, and obstruction of lacrimal passage will not be caused after implantation.
Description
Technical field
The utility model relates to ophthalmic medical fields, specifically a kind of to be directed to punctal stenosis patient, and it is small to carry out tear
After point proliferation film resection operation, it is placed in puncta original position, keeps puncta fully formed, prevents punctal stenosis postoperative recurrence
Device.
Background technique
Punctal stenosis patient, because puncta is covered by proliferation film, tear cannot be introduced into lacrimal passage, usually cause patient's tear
It overflows, influences patients ' life quality.And treatment of the existing ophthalmology for punctal stenosis patient, it relies primarily on and is proliferated film under microscope
The incidence of resection operation, but simple excision, postoperative proliferation film recurrence is higher.Previously have operation after place lacrimal point embolus into
The report of row puncta forming, but the design of various puncta emboluses mainly plays Lacrimal plug at present, it can people after placement
It is postoperative to have the adverse consequences shed tears to cause tear drainage unsmooth, and lacrimal point embolus main body is hidden in lacrimal point and tear completely
In tubule, and the proliferation film of punctal stenosis is often positioned in the surface of puncta, therefore not for the forming of puncta effect
It is good.In the prior art, the device for the forming of punctal stenosis lacrimal point, yet there are no report.
Summary of the invention
The purpose of the utility model is to provide one kind to comply fully with puncta physiology and anatomic form, is easily placed, implantation
After be not easy, the punctal stenosis lacrimal point device special for shaping of obstruction of lacrimal passage will not be caused after implantation.
In order to achieve the above object, the utility model provides a kind of lacrimal point of ophtalmic treatments punctal stenosis into shape dress
It sets, which is characterized in that including hollow body, the outside of hollow body is equipped with the first annular of the ampulla for blocking puncta
Fixed structure and the second annular anchoring structures.
Preferably, the first annular fixed structure and the second annular anchoring structures are arranged in parallel, and it is small to be located at tear
The upper side and lower side of the ampulla of point.
Preferably, the hollow body is grouped by cylindrical part and the conical portion on the downside of cylindrical part
At first annular fixed structure and the second annular anchoring structures are set on the outside of cylindrical part.
It is highly preferred that the upper end opening of the cylindrical part, the lower end and side of conical portion are equipped with priming hole,
Upper end opening is all connected to the hollow space of hollow body with priming hole.
Preferably, the outer diameter of the first annular fixed structure and the second annular anchoring structures is greater than the ampulla of puncta
The internal diameter in portion.
Preferably, the first annular fixed structure is located at the upside of the second annular anchoring structures, first annular fixation
The outer diameter of structure is greater than the outer diameter of the second annular anchoring structures.
Compared with prior art, the utility model has the beneficial effects that
(1) the utility model complies fully with puncta physiology and anatomic form, is easily placed, and is not easy after implantation, plants
It will not cause obstruction of lacrimal passage after entering.
(2) global shape meets the form of puncta ampulla after the utility model is placed, and puncta is not influenced after implantation
The physiological function of sphincter.
(3) annular anchoring structures of the utility model use flat annular design, are greater than puncta diameter, therefore device will not
To lacrimal internal shift, cause artificial obstruction of lacrimal passage risk, and the design can well with conjunctiva around lacrimal point and skin histology
Fitting is not easy to cause postoperative because of foreign body sensation caused by device rubs.
(4) the utility model blocks the ampulla of puncta by annular anchoring structures to fix, and is not easy after implantation.
(5) the utility model is designed using hollow pipeline, and device head uses porous design, and puncta is not influenced after implantation
Tear drainage function.
(6) the utility model lower end uses conical design, is easy to fix by puncta implantation lacrimal initial part.

Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
Embodiment
As shown in Figure 1, the lacrimal point forming device of the ophtalmic treatments punctal stenosis of the present embodiment, including hollow body 1, in
The outside of empty ontology 1 is equipped with first annular fixed structure 2 and the second annular anchoring structures for blocking the ampulla of puncta
3.The first annular fixed structure 2 and the second annular anchoring structures 3 is arranged in parallel, and is located at the ampulla of puncta
The upper side and lower side.
The hollow body 1 is grouped as by cylindrical part and the conical portion on the downside of cylindrical part, the
One annular anchoring structures 2 and the second annular anchoring structures 3 are set to the outside of cylindrical part.The upper end of the cylindrical part
Opening, the lower end and side of conical portion are equipped with priming hole 4, upper end opening and hollow portion of the priming hole 4 all with hollow body 1
Divide connection.
The outer diameter of the first annular fixed structure 2 and the second annular anchoring structures 3 is greater than the ampulla of puncta
Internal diameter.The first annular fixed structure 2 is located at the upside of the second annular anchoring structures 3, first annular fixed structure 2 it is outer
Diameter is greater than the outer diameter of the second annular anchoring structures 3.
The material of the lacrimal point forming device of the ophtalmic treatments punctal stenosis of the present embodiment is medical grade silicone, can pass through height
Warm autoclave sterilization product material cost is cheap, convenient for production.Design has different diameter specifications, and the tear for being suitable for all size is small
Point.
After carrying out punctal stenosis proliferation film resection operation, conjunctival sac point surface anesthesia drug, with Special-purpose forceps clamping the
Cylindrical part between one annular anchoring structures 2 and the second annular anchoring structures 3 is small by device lower end aligned tear under microscope
Point is placed, firmly hold-down devices, and until the second annular anchoring structures 3 are by puncta ampulla, release Special-purpose forceps are placed in
