Abstract
A device configured for use in an ocular surgical procedure is provided. The device, such as a sleeve or a needle, includes a proximal portion, a distal portion including at least one fluid opening formed at a predetermined orientation, and at least one visual marking provided at the proximal portion at a predetermined marking orientation relative to said predetermined orientation. The visual marking or markings provide a visual indication of orientation of the fluid opening when the device is employed in the ocular surgical procedure.
Claims20
A device configured for use in an ocular surgical procedure, comprising:
- a proximal portion substantially oriented along a central axis;
- a needle that includes a distal portion substantially oriented along the central axis and comprising a first fluid opening that is formed at a predetermined orientation with regard to the central axis;
- a sleeve that includes a second fluid opening and a third fluid opening, wherein the second fluid opening and the third fluid opening are orthogonal to the first fluid opening;
- at least one first visual marking located on a surface of the proximal portion suitable for providing a first visual indication of the predetermined orientation when the first fluid opening is at least partially obscured during the ocular surgical procedure;
- at least one second visual marking located on a surface of the sleeve and suitable for providing a second visual indication of a location of the second fluid opening;
- and
- at least one third visual marking located on the same surface of the sleeve as the at least one second visual marking and suitable for providing a third visual indication of a location of the third fluid opening.
A sleeve device configured for use with a needle in a surgical procedure, the needle forming a central axis, the sleeve device comprising:
- a proximal sleeve portion substantially oriented about the central axis;
- a distal sleeve portion substantially oriented about the central axis and comprising:
- an opening configured to enable the needle to pass therethrough, wherein the needle includes a first opening formed at a predetermined orientation with respect to the central axis
- a second opening orthogonal to the first opening that is configured to enable fluid to pass therethrough, and
- a third opening orthogonal to the first opening that is configured to enable fluid to pass therethrough;
- at least one first visual marking located on a surface of the proximal sleeve portion suitable for providing a visual indication of the predetermined orientation when the first opening is at least partially obscured during the surgical procedure;
- at least one second visual marking located on a surface of the sleeve for providing a second visual indication of a location of the second opening;
- and
- at least one third visual marking located on the same surface of the sleeve as the at least one second visual marking for providing a third visual indication of a location of the third opening.
A device configured for use in a surgical procedure, comprising:
- a proximal portion oriented along a central axis;
- a needle that includes a distal portion oriented along the central axis and comprising a first opening formed in a predetermined orientation relative to a plane that crosses the central axis, wherein the first opening is configured to permit fluid to pass therethrough;
- a sleeve that includes a second opening formed orthogonal to the first opening, wherein the second opening is configured to permit fluid to pass therethrough, and a third opening formed orthogonal to the first opening, wherein the third opening is configured to permit fluid to pass therethrough;
- at least one first visual marking comprising at least one protrusion formed in and raised outward from a surface of the proximal portion and located at the proximal portion and suitable for providing a visual indication of the predetermined orientation when the first opening is at least partially obscured during the surgical procedure;
- at least one second visual marking located on a surface of the sleeve and suitable for providing a second visual indication of a location of the second opening;
- and
- at least one third visual marking located on the same surface of the sleeve as the at least one second visual marking and suitable for providing a third visual indication of a location of the third opening.
