Abstract
A surgical clip applier includes a counter assembly including a counting wheel with a plurality of actuation features, a locking spring assembly, a driver, and a pin assembly. The counting wheel includes indicia visible through the handle assembly. The locking spring assembly is positioned within the counting wheel and is configured to prohibit multidirectional rotation of the counting wheel. The driver includes a grasping protrusion and a positioning protrusion. The driver translates between a proximal position and a distal position, wherein the grasping protrusion engages the plurality of actuation features to rotate the counting wheel to change the indicia. The pin assembly is configured to engage with the positioning protrusion of the driver, wherein during transitioning of the driver from the proximal position to the distal position, the positioning protrusion engages the stationary pin to pivot the driver, whereby the driver disengages from the plurality of actuation features.
