Retinal fabric and its attachment method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 망막용 택을 부착시키기 위한 시스템의, 일부를 개략적으로 나타낸 사시도이다.1 is a schematic perspective view of a portion of a system for attaching a tag for a retina of the present invention.

Claims

A retinal tag for anchoring the detached retina to the choroid, wherein the sharp anterior end for penetrating the retina, choroid and sclera.

An elongated retainer extending rearward from the anterior end and having a length approximately equal to the thickness of the patient's retina, choroid and sclera, wherein one or more annular grooves are formed to enter the sclera tissue displaced by the anterior end during insertion;

And a large head having a flange portion extending radially outward to contact the retina at a portion extending rearward from the retaining portion and surrounding the hole formed by the front end.

4. The tack of claim 1, wherein the tack is detachably carried by an outer end of the tubular probe that has a tip and is in fluid communication with a pressure source lower than atmospheric pressure;

A retinal tack contained in the head from a sheet received in a corresponding sheet at the probe tip to be in sealing contact.

3. The retinal tack of claim 2, wherein said sheet portion is tapered radially inward toward the rear.

4. The head of claim 3, wherein the head includes a collar extending rearward from a flange and a small diameter bag rearwardly extending from the collar; And the sheet includes a taper portion connecting the bag portion and the collar.

The device of claim 1, wherein the front end is generally conical; The holding part has a generally cylindrical outer surface; Each groove having a front rear sidewall extending radially outward, the front sidewall defining a sharp edge with the outer surface of the retaining portion.

6. The ophthalmic tag according to claim 5, wherein the rear sidewall of the hop is inclined outwardly toward the rear.

7. The ophthalmic tag according to claim 6, wherein the holding portions are formed with the plurality of grooves spaced along the length.

Preparing a tag for the retina having a large head suitable for insertion through the retina, choroid and sclera, and in contact with the retina after insertion; Accommodating a head of the retina tack to prepare a tubular probe having a front end sealingly coupled thereto and an inner passage extending from the front end; Positioning the head of the retina tack within the tip of the probe and reducing the pressure in the probe inner passageway below atmospheric pressure to maintain the tack detachably within the probe tip; The probe is inserted into the vitreous space through the eye hole and allows the nucleus for the retina to penetrate the retina, choroid and sclera until the head of the tack contacts the retina and the retina contacts the choroid near the detached area of the retina. step ; Applying a pressure slightly higher than atmospheric pressure to the inner passage of the probe to release the probe from the retinal tag; A method of anchoring the exfoliated retina to the choroid comprising the step of exiting the probe from the vitreous space through an eye hole.
