A surgical instrument includes a housing having a barrel defining an axis and a fixed handle extending from the barrel. The barrel includes at least one elongated indentation and the fixed handle defines a waist. A shaft extends from the barrel along the axis and couple to an end effector at a distal end thereof. A movable handle coupled to the housing is configured to manipulate the end effector. The movable handle includes a proximal leg, a distal tail, an arcuate segment defining a finger-retaining area, and a proximal foot. A deployable member is slidably disposed within the shaft. A trigger coupled to the housing is configured to deploy the deployable member. The trigger defines a saddle portion. The housing, movable handle, and trigger are configured to facilitate operable grasping by a hand of a user in at least first and second different grasping configurations. |

1. A surgical instrument, comprising:
a housing including a barrel portion defining a longitudinal axis and a fixed handle portion extending from the barrel portion transversely relative to the longitudinal axis, the barrel portion including at least one elongated indentation, the fixed handle portion defining a recessed waist adjacent the barrel portion; a shaft extending distally from the barrel portion of the housing along the longitudinal axis; an end effector assembly coupled at a distal end of the shaft; a movable handle coupled to the housing and configured to manipulate the end effector assembly, the movable handle including a proximal leg defining a first end and a second end, a distal tail, an arcuate segment interconnecting the proximal leg and distal tail at the first end of the proximal leg to define a finger-retaining area therebetween, and a proximal foot disposed at the second end of the proximal leg to define a grasping surface between the first and second ends of the proximal leg; a deployable member slidably disposed within the shaft; and a trigger coupled to the housing and configured to deploy the deployable member relative to the end effector assembly, the trigger defining a saddle portion configured to receive a finger of a user, wherein the housing, movable handle, and trigger are configured to facilitate operable grasping by a hand of a user in at least first and second grasping configurations and wherein, in each grasping configuration, a user's fingers are arranged differently relative to the elongated indentation, recessed waist, finger-retaining area, grasping surface, and saddle portion. |
