Abstract

Current articulating clip appliers store clips proximal to the end effector and distal to the articulation joint, which lengthens the region being articulated. Packing clips more efficiently in the distal region of an articulation joint could reduce the articulating length of a clip applier. This can be achieved through a system of vertically stacked clips with a passively driven, screw-fed advancement mechanism.

ARTICULATING CLIP APPLIER VERTICAL CLIP STACK: SCREW-FED ADVANCEMENT MECHANISM

SUMMARY

Current articulating clip appliers store clips proximal to the end effector and distal to the articulation joint, which

lengthens the region being articulated. Packing clips more efficiently in the distal region of an articulation joint

could reduce the articulating length of a clip applier. This can be achieved through a system of vertically stacked

clips with a passively driven, screw-fed advancement mechanism.

DESCRIPTION

A novel method for tighter packing of clips in a multiple clip articulating clip applier, with a screw-fed clip

advancement mechanism. The stacked clips would be placed distal to the articulation joint to allow for maximum

maneuverability of the jaws.

After firing, the screw-fed platform would apply enough force to push the next clip onto the firing sled to be

loaded into the jaws. The screw is driven by a pulley and cable system which powers the rotation.
