Clip counting mechanism for surgical clip applier
Abstract:
A clip counting mechanism for use with a surgical clip applier includes a display gear rotatably supported within a handle housing of the surgical clip applier and including an outer surface having a plurality of numbers disposed thereon, a biasing element in mechanical communication with the display gear and rotatably biasing the display gear, a counter switch reciprocally disposed within the handle housing and defining a cam slot therethrough, and an escapement gear rotatably supported within the handle housing and defining a proximal end portion in mechanical communication with the display gear and a distal end portion in mechanical communication with the cam slot. Translation of the counter switch causes the cam slot to cam the escapement gear and selectively disengage and then re-engage the display gear to enable the display gear to rotate a predetermined angle of rotation.
