1. A surgical instrument, comprising:
a housing; and
a trigger assembly operably coupled to the housing for selectively deploying a deployable component distally relative to the housing, the trigger assembly including:
a trigger including a drive portion and a manipulation portion, the trigger pivotably coupled to the housing at a position between the drive portion and the manipulation such that the drive portion and the manipulation portion are moved in different directions in response to pivoting of the trigger relative to the housing;
a rocker, wherein the drive portion of the trigger is pivotably coupled to the rocker about a first pivot axis;
a linkage including a first end portion pivotably coupled to the rocker about a second pivot axis spaced-apart from the first pivot axis and a second end portion pivotably coupled to the housing about a third pivot axis fixed relative to the housing; and
a slider slidably disposed within the housing, pivotably coupled to the rocker about a fourth pivot axis different from the first pivot axis and second pivot axis, and operably coupled to the deployable component,
wherein proximal actuation of the manipulation portion of the trigger moves the drive portion of the trigger distally to thereby urge the rocker distally, pivot the linkage about the second end portion thereof, and slide the slider distally relative to the housing to deploy the deployable component distally.
