The present disclosure describes a three-pronged forceps. The forceps are particularly useful for removing an intraocular lens from an eye.

Claims13

Dependent claims

A grasping device, comprising:

a first prong including a proximal end, a distal end, an inner surface extending between the proximal end and the distal end, and an outer surface opposite the inner surface and extending between the proximal end and the distal end;
a second prong including a proximal end, a distal end, an inner surface extending between the proximal end and the distal end of the second prong, and an outer surface opposite the inner surface of the second prong and extending between the proximal end and the distal end of the second prong;
a third prong including a proximal end and a distal end, the third prong being positioned between the first prong and the second prong;
a first guide coupled to the first prong;
a second guide coupled to the second prong;
and a third guide coupled to the third prong, wherein the proximal end of the first prong, the proximal end of the second prong, and the proximal end of the third prong are coupled to one another, and wherein the distal end of the first prong, the distal end of the second prong, and the distal end of the third prong are movable relative to one another between a first position and a second position, wherein in the first position, the outer surface at the distal end of the first prong and the outer surface at the distal end of the second prong are spaced apart from one another by a first distance and the distal end of the third prong is positioned below the distal ends of the first prong and the second prong;
and wherein in the second position, the outer surface at the distal end of the first prong and the outer surface at the distal end of the second prong are spaced apart from one another by a second distance that is smaller than the first distance and the distal end of the third prong is positioned above the distal ends of the first prong and the second prong wherein when the first prong and the second prong move between the first position to the second position, the third guide on the third prong moves along the first guide and the second guide to move the third prong between the first position and the second position.
