Abstract
A counter assembly is supported in a handle assembly of a clip applier. The counter assembly includes a counting mechanism, a ratchet mechanism, and an actuator. The counting mechanism is positioned to rotate within the handle assembly and includes indicia visible through the handle assembly. The ratchet mechanism is rotationally coupled to the counting mechanism and prohibits multidirectional rotation of the counting mechanism. The actuator includes a protrusion projecting therefrom. The actuator is positioned to translate between a proximal position and a distal position, wherein the protrusion of the actuator engages the counting mechanism to rotate the counting mechanism, in a first direction, to adjust the indicia of the counting mechanism, which is visible through the handle assembly. In the proximal position, the protrusion of the actuator is disposed proximal of the counting mechanism. In the distal position, the protrusion of the actuator is disposed distal of the counting mechanism.
