Abstract
An ocular fixation device includes a body configured to be placed on an eye. The ocular fixation device also includes multiple twist picks configured to be turned to secure the body to the eye and to release the body from the eye. The body includes connection points on which a surgical tool is mountable on the body.
Claims22
An ocular fixation device comprising:
- a body comprising a central portion completely defining a central opening and four projections connected to sides of the central portion and extending from the central portion in four different directions, the projections not connected to one another, the projections having slanted inner edges configured to lie on an outer surface of an eye, the body also comprising multiple first openings;
- and
- multiple twist picks configured to be inserted into the first openings of the body, the twist picks also configured to attach the body to a sclera or a limbus of the eye and to release the body from the sclera or the limbus of the eye;
- wherein the body further comprises multiple connection points on which a surgical tool is mountable on the body, the connection points comprising second openings in top surfaces of the projections;
- wherein each projection comprises (i) one of the first openings and (ii) one of the second openings positioned such that the first opening of the projection is located farther away from the central portion of the body than the second opening of the projection;
- and
- wherein each twist pick comprises two angled projections at an end of the twist pick, each angled projection configured to (i) enter into the sclera or the limbus of the eye in response to rotation of the twist pick in a first direction and (ii) exit the sclera or the limbus of the eye in response to rotation of the twist pick in a second direction.
