Abstract

A capsular retractor includes an elongated shaft, a hook portion extending from a distal end portion of the elongated shaft, a handle portion extending from a proximal end portion of the elongated shaft, and first and second grasping segments formed with or attached to the handle portion. The grasping segments are configured to be selectively grasped for manipulating the ophthalmic surgical instrument regardless of the rotational orientation of the handle portion.

Claims

1. An ophthalmic surgical instrument for stabilizing a lens capsule, comprising:

an elongated shaft having a proximal end portion and a distal end portion;

a hook portion extending from the distal end portion of the elongated shaft;

a handle portion extending from the proximal end portion of the elongated shaft;

a first arm extending laterally from and being monolithically formed with the handle portion; and

a second arm extending laterally from and being monolithically formed with the handle portion and longitudinally spaced along the elongated shaft from the first arm, the first and second arms oriented at a non-parallel angle relative to one another, wherein the first and second arms are configured to be selectively grasped for manipulating the ophthalmic surgical instrument, and wherein the first and second arms each extend laterally the same distance from the handle portion as one another.

2. The ophthalmic surgical instrument according to claim 1, wherein the angle between the first and second arms is from about 10 degrees to about 90 degrees.

3. The ophthalmic surgical instrument according to claim 1, wherein the first and second arms are perpendicular to one another and a longitudinal axis defined by the handle portion.

4. The ophthalmic surgical instrument according to claim 1, wherein the first arm has a first end portion projecting from a first side of the handle portion, and a second end portion projecting from a second side of the handle portion.

5. The ophthalmic surgical instrument according to claim 4, wherein the second arm has a first end portion projecting from a third side of the handle portion, and a second end portion projecting from a fourth side of the handle portion.

6. The ophthalmic surgical instrument according to claim 5, wherein the first and second sides of the handle portion oppose one another, and the third and fourth sides of the handle portion oppose one another.

7. The ophthalmic surgical instrument according to claim 1, wherein the hook portion extends at an acute angle relative to a longitudinal axis defined by the elongated shaft.

8. The ophthalmic surgical instrument according to claim 7, wherein the handle portion extends at an obtuse angle relative to the longitudinal axis of the elongated shaft.

9. The ophthalmic surgical instrument according to claim 7, wherein the elongated shaft defines:

a first longitudinally-extending plane; and

a second longitudinally-extending plane, perpendicular to the first plane, the hook portion and the handle portion being coplanar with the first plane, and the hook portion and the handle portion being disposed on opposite sides of the second plane.

10. The ophthalmic surgical instrument according to claim 1, wherein each of the first and second arms has a flat, rectangular shape.

11. The ophthalmic surgical instrument according to claim 1, further comprising a stopper disposed about the handle portion at a location distally of the first and second arms.

12. An ophthalmic surgical instrument for stabilizing a lens capsule, comprising:

an elongated shaft defining a longitudinal axis and having a proximal end portion and a distal end portion;

a hook portion extending at an acute angle relative to the distal end portion of the elongated shaft; and

a handle assembly attached to the proximal end portion of the elongated shaft and including;

an elongated handle portion;

a first arm extending outwardly from opposite first and second sides of the elongated handle portion; and

a second arm extending outwardly from opposite third and fourth sides of the elongated handle portion, wherein the first and second arms are configured to be selectively grasped for manipulating the ophthalmic surgical instrument, and wherein the first and second arms each extend outwardly the same distance from the elongated handle portion as one another.

13. The ophthalmic surgical instrument according to claim 12, wherein the first and second arms are oriented at a non-parallel angle relative to one another.

14. The ophthalmic surgical instrument according to claim 13, wherein the angle between the first and second arms is from about 45 degrees to about 90 degrees.

15. The ophthalmic surgical instrument according to claim 12, wherein the first and second arms are perpendicular to one another and the longitudinal axis of the elongated handle portion.

16. The ophthalmic surgical instrument according to claim 12, wherein the elongated shaft defines:

a first longitudinally-extending plane; and

a second longitudinally-extending plane, perpendicular to the first plane, the hook portion and the elongated handle portion being coplanar with the first plane, and the hook portion and the elongated handle portion being disposed on opposite sides of the second plane.

17. The ophthalmic surgical instrument according to claim 12, wherein each of the first and second arms has a flat, rectangular shape.

18. A capsular retractor, comprising:

an elongated shaft having a proximal end portion and a distal end portion;

a hook portion extending from the distal end portion of the elongated shaft; and

an elongated handle portion attached to the distal end portion of the elongated shaft and including;

a first depression formed in the elongated handle portion; and

a second depression formed in the elongated handle portion and disposed perpendicular to the first depression, wherein the first and second depressions are configured to be selectively grasped for manipulating the ophthalmic surgical instrument.

19. The ophthalmic surgical instrument according to claim 18, wherein the second depression is disposed distally of the first depression.

20. The ophthalmic surgical instrument according to claim 18, wherein each of the first and second depressions is flat relative to a remainder of the elongated handle portion and defines a plane, the plane of the first depression being perpendicular to the plane of the second depression, and wherein the first and second depressions extend longitudinally along a longitudinal axis defined by the elongated handle portion.
