Abstract
A counter assembly includes a first housing half, a second housing half, a stationary post, a counting wheel, an actuation wheel, and an actuator. The stationary post is positioned within the first housing half and includes a plurality of locking teeth. The counting wheel includes indicia. The actuation wheel includes a plurality of actuation features and a plurality of inner fingers configured to selectively engage with the plurality of locking teeth of the stationary post. The engagement of the plurality of inner fingers and the plurality of locking teeth prohibit multidirectional rotation of the counting wheel. The actuator includes a protrusion projecting therefrom. The actuator is positioned to translate between a proximal position and a distal position. The protrusion of the actuator engages the plurality of actuation features to rotate the counting wheel to adjust the indicia thereof when the actuator transitions from the proximal position and the distal position.
