Abstract:
1. A surgical needle holder, comprising: a first elongate arm having a first annular finger grip at one end, said first elongate arm extending into a stationary first gripper jaw at a distal end opposite the finger grip; a fulcrum attachment member disposed between the opposing distal and finger grip ends of the first elongate arm; a vertical slot disposed in said fulcrum attachment member; horizontally aligned pivot through-bores disposed through the vertically slotted portion of said fulcrum attachment member; an extension of said fulcrum attachment member forming a horizontally disposed slotted portion; vertically aligned pivot through-bores disposed through said horizontally disposed slotted portion of said fulcrum attachment member; a second elongate arm having a second annular finger grip at one end, said second elongate arm extending into a planar attachment member at a distal end opposite the finger grip, said planar attachment member having a polygonal shape with an apical portion joined to a tapered region of the second elongate arm; lower and upper through-bores disposed in vertical alignment on the planar attachment member near an edge of the planar attachment member opposing its apical portion, the upper through-bore of the planar attachment member being in alignment with the horizontally aligned pivot through-bores of the fulcrum attachment member; a fastening pin disposed through said upper through-bore and said horizontally aligned pivot through-bores to pivotally fasten said first and second elongate arms to each other, portion of said planar attachment member that includes said lower through-bore being exposed, extending below said vertical slot of said fulcrum attachment member; a second gripper jaw tapering from a proximal thick end to a distal narrow end, shape of said second gripper jaw substantially and complementarily matching shape of said first gripper jaw; a horizontally extending planar attachment cam, a narrow portion thereof attaching said cam to said thick end of said second gripper jaw, a wide lobe portion of said cam opposing said narrow cam portion, first and second cam through-bores disposed in horizontal alignment near an edge of said wide lobe cam portion, said cam being disposed through a horizontal slot of said horizontally slotted portion placing said first cam through-bore in alignment with said vertically aligned pivot through-bores in the horizontally slotted portion of the fulcrum attachment member, said second cam through-bore being exposed through the horizontal slot; a fastening pin disposed through said first cam through-bore and said vertically aligned pivot through-bores to pivotally fasten said second gripper jaw with respect to said first gripper jaw; and an elongate actuator rod having a horizontal bend at a first end and a vertical bend at a second end, the first end being pivotally attached to said exposed lower-through-bore of said planar attachment member, said second end being pivotally attached to said exposed second bore of said cam thereby linking pivotal motion of said arms to pivotal opening and closing of said pivotal second gripper jaw with respect to said stationary first gripper jaw, said arm pivotal motion being displaced by 90° from said gripper jaw pivotal motion.
