Lens insertion instrument
First Claim
1. A lens holder for a surgical instrument used or inserting an intraocular lens into the eye comprising:
- an elongated stylet having a proximal end and a distal end and having an exterior surface;
a flexible paddle;
means for affixing said paddle to the distal end of said stylet so that said paddle extends distally from the distal end of said stylet including a slot extending transversely into said exterior surface of said stylet for receiving a portion of said paddle; and
wherein the distal portion of said paddle includes a lens holding portion and the proximal portion of said paddle includes a mounting portion said mounting portion including margins to wrap around a distal portion of said stylet and fit into said slot.

Abstract
An insertion tool for an intraocular lens including a hollow barrel, a rigid annular tube extending from the distal end of the barrel, the stylet for reciprocating within the barrel and the rigid tube, an actuator extending through the side wall of the barrel and connected to the stylet to permit the user to move the stylet back and forth within the barrel. A paddle is attached to the distal end of the stylet. The intraocular lens is loaded into the paddle and then the paddle and the lens are retracted into the rigid tube for insertion into the eye through a small incision. The paddle unfolds the lens as it is retracted into the tube. When the distal end of the instrument is placed into the eye, the paddle and lens are ejected from the tube so that the lens may be deposited within the eye.

5. A surgical instrument for inserting an intraocular lens into the eye comprising:
-
an elongated stylet having a proximal end and a distal end and having an exterior surface; a flexible paddle having a proximal and a distal portion; means for affixing said flexible paddle to the distal end of said stylet so that said paddle extends distally from said stylet; an axially extending generally annular tube having a distal end and a proximal end adapted to permit said stylet to reciprocate axially within said tube to permit said paddle to be retrated within said tube or to be ejected out of said tube; a generally annular hollow barrel; means cooperatively disposed on the distal end of said hollow barrel and the proximal end of said tube for connecting the two together; a slot extending through the side wall of said barrel; means for mounting said stylet for axial reciprocation within said barrel; actuation means disposed along the outside surface of said barrel and at least partially projecting through said slot; and
,means for operably connecting said actuation means to said stylet so that as said actuation means is moved with respect to said slot, said stylet will move with respect to said barrel to eject a lens into the eye. - View Dependent Claims (6, 7, 8, 9, 10)

11. A lens holder for a surgical instrument used or inserting an intraocular lens into the eye comprising:
-
an elongated stylet having a proximal end and a distal end and having an exterior surface; a flexible paddle; means for affixing said paddle to the distal end of said stylet so that said paddle extends distally from the distal end of said stylet including an annular sleeve adapted to fit about the distal end of said stylet; wherein the distal portion of said paddle includes a lens holding portion and the proximal portion of said paddle includes a mounting portion wherein said mounting portion wraps around a distal portion of said stylet; and wherein said annular sleeve is adapted to fit tightly about the distal portion of said stylet and about the exterior surface of said mounting portion to provide a tight fit to hold said paddle in position. - View Dependent Claims (12)
