Abstract
An actuation mechanism, and a handle assembly and a surgical clip applier including the same are disclosed. The actuation mechanism includes a drive bar movable through a stroke having first and second stroke portions and an output gear rack. First and second intermediate gears include input portions operably coupled to a trigger and output portions defining different diameters. In the first stroke portion, the output portion of the first intermediate gear is engaged with the gear rack such that the first intermediate gear drives the drive bar. In the second stroke portion, the output portion of the second intermediate gear is disposed in engagement with the gear rack such that the second intermediate gear drives the drive bar. A different mechanical advantage is provided in the first portion of the stroke length as compared to the second portion of the stroke length.
