Endoscopic surgical clip applier including counter assembly
First Claim
1. A surgical clip applier, comprising:
- a handle assembly;
an elongated tubular member extending distally from the handle assembly;
a rack bar translatably supported in the handle assembly;
a counter assembly supported in the handle assembly, the counter assembly including;
a housing including a first housing half and a second housing half;
a stationary post positioned within the first housing half and including a plurality of locking teeth;
a counting wheel positioned to rotate within the housing, the counting wheel including indicia visible through the handle assembly;
an actuation wheel including 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, wherein the engagement of the plurality of inner fingers of the actuation wheel and the plurality of locking teeth of the stationary post prohibit multidirectional rotation of the counting wheel; and
an actuator supported on the rack bar for translation therewith, the actuator including a protrusion projecting therefrom, the actuator positioned to translate between a proximal position and a distal position, wherein transitioning between the proximal position and the distal position, the protrusion of the actuator engages the plurality of actuation features to rotate the counting wheel to adjust the indicia of the counting wheel.

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.
