US 2003/0171762 A1 · Instrument dispenser

Abstract

An instrument dispenser having an actuation handle made from springy material having a memory. Squeezing the handle causes the dispenser to elongate, thereby causing movement in the distal end of the dispenser tip. The tip has a ratcheting mechanism so that the movement is in the forward direction only. The tip further contains a sclerotomy lance with a shaft slightly larger in diameter than an aperture in the wound clamp. A plurality of wound clamps may be held on the tip about the lance so that the shaft of the lance spreads the halves of the wound clamps apart slightly. The wound clamps are pushed forward by the ratcheting movement of the tip and deposited at the surgical site. The dispenser of the present invention may be held and actuated in any position by a single hand.

Dependent claims

An instrument dispenser, comprising:

a) a compressible actuation handle having a proximal end and a distal end;
b) an actuation sleeve on the distal end of the actuation handle;
c) a ratcheting sleeve connected to the actuation sleeve;
d) a ridged sleeve telescopically received within the ratcheting sleeve;
and
d) a lance telescopically received through the ridged sleeve, the ratcheting sleeve and the actuation sleeve, the ridged sleeve being fixed to the lance so that compression of the actuation handle causes elongation of the actuation handle and resulting reciprocal movement of the actuation sleeve and the ratcheting sleeve along the lance.
