1. An ophthalmic surgery instrument comprising:
- an instrument handle having a hollow interior bore;
a rigid tubular sleeve projecting from the handle, the sleeve having reduced dimensions that allow insertion of the sleeve through an eye incision in ophthalmic surgery procedures, the sleeve having a hollow interior bore that communicates with the handle interior bore;
an optic fiber extending through the handle interior bore and the sleeve interior bore to a distal end portion of the fiber, the optic fiber being movable relative to the handle and the sleeve, the sleeve surrounding the optic fiber in close proximity to the optic fiber with a majority of the sleeve interior bore being occupied solely by the optic fiber whereby cross-sectional dimensions of the sleeve and optic fiber are minimized for use in minimally invasive surgery; and
a mechanism on the handle and connected to the optic fiber to selectively move the optic fiber between a pushed forward position of the optic fiber where the optic fiber projects a first distance from the handle and a pulled back position of the optic fiber where the optic fiber projects a second distance from the handle that is less than the first distance.

Abstract
A microsurgical laser probe is provided with a distal end portion of an optic fiber that projects from a tubular sleeve of the probe and can be caused to bend relative to the probe sleeve by manual manipulation of a mechanism on a handle of the probe.

19. An ophthalmic surgery instrument comprising:
-
an instrument handle having a hollow interior bore; a rigid tubular sleeve projecting from the instrument handle, the sleeve being fixed stationary relative to the handle, the sleeve having reduced dimensions that allow insertion of the sleeve through an eye incision in ophthalmic surgery procedures and the sleeve having a hollow interior bore through the sleeve that communicates with the handle interior bore; an optic fiber extending through the handle interior bore and the sleeve interior bore to a distal end portion that projects from the sleeve, the distal end portion of the optic fiber having an adjustable bend therein, the optic fiber being movable relative to the handle and the sleeve, and the sleeve surrounding the optic fiber in close proximity to the optic fiber with a majority of the sleeve interior bore being occupied solely by the optic fiber whereby cross-sectional dimensions of the sleeve and optic fiber are minimized for minimally invasive surgery. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A surgical instrument comprising:
-
an instrument handle; a rigid tubular sleeve projecting from the instrument handle, the sleeve being fixed stationary relative to the handle; an optic fiber extending through the handle and the sleeve to a distal end portion that projects from the sleeve, the distal end portion of the optic fiber having an adjustable bend therein, the optic fiber being movable relative to the handle and the sleeve; the tubular sleeve has an interior surface and a layer of sliding material between the sleeve interior surface and the optic fiber in the sleeve; and
,the layer of sliding material is located in only a portion of the sleeve creating an air gap between the sleeve interior surface and the optic fiber where the layer of sliding material is not located.

37. An ophthalmic surgery instrument comprising:
-
an instrument handle having a hollow interior bore; a rigid tubular sleeve projecting from the instrument handle, the sleeve having reduced dimensions that allow insertion of the sleeve through an eye incision in ophthalmic surgery procedures, the sleeve having a hollow interior bore that communicates with the handle interior bore; an optic fiber extending through the handle interior bore and the sleeve interior bore to a distal end portion that projects from the sleeve, the distal end portion of the optic fiber having an adjustable bend therein, the optic fiber being movable relative to the handle and the sleeve, the sleeve surrounding the optic fiber in close proximity to the optic fiber with a majority of the sleeve interior bore being occupied solely by the optic fiber whereby cross-sectional dimensions of the sleeve and optic fiber are minimized for use in minimally invasive surgery; and
,the handle has a mechanism that is connected to the optic fiber and selectively moves the optic fiber between pushed forward and pulled back positions of the optic fiber relative to the handle. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44)
