International Classification:

A61B 1732

US Classification:

128305

Abstract:

An ophthalmic surgical instrument (10) is provided for incising the anterior lens capsule of the crystalline lens of an eye. The surgical instrument (10) includes a handle (12) adapted for support in a hand of a user. A tubular member (16) extends from the handle (12) and terminates in a loop (18). A circular cutting device (20) is rotatably mounted within the loop (18). A flexible elongate wire (24) is disposed within the tubular member (16) and is interconnected to the circular cutting device (20) and the handle (12) such that the circular cutting device (20) is rotated upon compression of the handle (12).

Abstract:

A ski exercise device (500) includes a stationary mainframe (502) and an arcuate track (520) having first (520a) and second (520b) ends. The ends (520a, 520b) of the arcuate track (520) are connected to the stationary mainframe (502). A support platform (540) is slidably mounted to the arcuate track (520). The support platform (540) moves along the arcuate track (520) between the ends (520a, 520b). Biasing structure (720) biases the support platform (540) to the arcuate track (520) such that the support platform (540) acts against the force created by the biasing structure (720) as the support platform (540) moves along the arcuate track (520). The support platform (540) supports the user of the ski exercise device (500) and allows for rotational and vertical motion of the user's feet during movement along arcuate track (520).

Abstract:

A contact lens (14) for insertion into the cornea (20) of a patient is provided. The contact lens (14) includes a circular portion of a donor cornea (10) anteriorly curved for correction of the patient's vision. The contact lens (14) is posteriorly ground (16) to correspond to the curvature of the patient's eye. The posterior portion (16) of the lens (14) includes a depending axially posteriorly directed integral ring (18) for insertion into and retention by the patient's cornea (20).

International Classification:

A61B 1720

US Classification:

604 22

Abstract:

An ophthalmic surgical instrument includes a handle adapted for support in the hand of a user. A rod is attahed to the handle. An elongated tubular member is disposed adjacent to the rod and is attached to the handle. The elongated tubular member is shorter than the rod. An actuator is mounted to the handle for movement between a forward position and a rearward position with respect to the handle. A flexible elongated wire is partially disposed within the elongated tubular member. The wire is attached to the second end of the rod and is attached to the actuator, such that movement of the actuator to the forward position causes the flexible elongated wire not disposed within the elongated tubular member to bow outwardly to partially encircle the lens of the eye thereby positioning the lens between the flexible elongated wire and the rod. Movement of the actuator to the rearward position causes the flexible elongated wire to retract within the elongated tubular member and move generally parallel to the rod to cut the lens.

Abstract:

An improved tip for a phacoemulsification needle having a proximal end attached to a phacoemulsification device, a distal end, a central longitudinal axis extending from the proximal end to the distal end with a bore within the needle concentric to the central axis thereof, so as to form a lumen, the lumen includes needle sidewalls having an inner and outer surface with an opening at the proximal and distal ends of the needle, the tip is formed by the distal opening which, when viewed from an angle perpendicular to the central longitudinal axis has a side view including a top wall located at a needle sidewall on one side of the central longitudinal axis. The top wall terminates in a top wall end face. The needle tip further includes a bottom wall located at a needle sidewall on the opposite side of the central longitudinal axis and extending distal of the end face of said top wall to form a tip projection. An end wall is disposed generally perpendicular to the tip projection.

Abstract:

A ski exercise device (20) includes a stationary mainframe (22) and an arcuate track (50) having first (50a) and second (50b) ends. The ends (50a, 50b) of the arcuate track (50) are connected to the stationary mainframe (22). A rail (70) having ends (70a, 70b) is provided. The rail (70) is pivotally mounted to the stationary mainframe (22) and includes a wheel (78) for engaging the arcuate track (50). The rail (70) moves along the arcuate track (50) between the ends (50a, 50b). Biasing structure (200) biases the rail (70) to the stationary mainframe (22) such that the rail (70) acts against the force created by the biasing structure (200) as the rail (70) moves along the arcuate track (50). Structure (90, 92) is provided which is mounted to the rail (70) for supporting the user of the ski exercise device (20) and which allows for longitudinal and rotational motion of the user's feet.

International Classification:

A61B 310

US Classification:

Abstract:

An instrument with a microscope brings into focus the cornea of a patient's eye for measurement of the radius of curvature of the cornea. Included is a pair of parallel spaced apart linear objects in a plane perpendicular to the optical axis of the eye and of the microscope. A square rod of refractile transparent material is mounted in the field of view of the microscope with a diagonal of the cross-section thereof common to the optical axis of the microscope. Structure is provided for rotating the rod around the optical axis of the microscope to produce a parallel line offset-overlap pattern of the objects as viewed through the rod. Structure is further provided for measuring the angle between a perpendicular from the long axes of the objects, and the orientation of the rod at which the pattern is produced.
