Abstract
A cannula support serves in supporting a cannula relative to a non-contact lens assembly and a positioning mechanism for positioning the non-contact lens assembly. The cannula support includes a cannula holder and a gripper disposed relative to the cannula holder. The cannula holder is provided for receiving at least a portion of the cannula. The gripper is adapted to cooperatively engage a portion of one of the non-contact lens assembly and the positioning mechanism.
Claims26
A cannula support for supporting a cannula relative to a non-contact lens assembly and a positioning mechanism for positioning the non-contact lens assembly, the cannula support comprising:
- a cannula holder, said cannula holder receiving at least a portion of the cannula;
- and
- a gripper disposed relative to said cannula holder, said gripper adapted to cooperatively engage a portion of one of the non-contact lens assembly and the positioning mechanism.
A method of irrigating an eye during eye surgery, comprising:
- providing a cannula support and a cannula having a tip;
- fixing the position of a portion of the cannula with the cannula support;
- positioning the tip of the cannula adjacent the eye;
- and
- actuating the cannula to provide a supply of fluid to the eye.
A method of performing surgery on an eye, comprising:
- providing a surgical microscope having focal axis;
- positioning the eye along the focal axis;
- positioning a non-contact lens assembly between the eye and the surgical microscope;
- adjusting the position of the non-contact lens assembly along the focal axis to focus the surgical microscope on the eye;
- providing a cannula support;
- fixing the position of a portion of a cannula adjacent the eye using the cannula support;
- and
- actuating the cannula to irrigate the eye with a supply of fluid.
An irrigation system for irrigating an eye during surgery, the irrigation system comprising:
- a cannula;
- and
- a cannula support comprising a cannula holder, said cannula holder receiving at least a portion of the cannula, and a gripper disposed relative to said cannula holder, said gripper adapted to cooperatively engage a portion of one of a non-contact lens assembly and a positioning mechanism for positioning the non-contact lens assembly relative the eye, wherein said cannula can be actuated to release a supply of fluid.
A positioning and irrigating system for use during eye surgery, the system comprising:
- a non-contact lens assembly;
- a positioning mechanism for positioning said non-contact lens assembly relative to the eye;
- a cannula;
- and
- a cannula support comprising a cannula holder, said cannula holder receiving at least a portion of the cannula, and a gripper disposed relative to said cannula holder, said gripper adapted to cooperatively engage a portion of one of the non-contact lens assembly and the positioning mechanism, wherein said cannula can be actuated to release a supply of fluid.
A surgical microscope assembly for use during eye surgery, comprising:
- a surgical microscope having a focal axis;
- a non-contact lens assembly;
- a positioning mechanism for positioning the non-contact lens along the focal axis;
- a cannula;
- and
- a cannula support for supporting said cannula, said cannula support being attached to one of said non-contact lens assembly and said positioning mechanism.
