SURGICAL INSTRUMENTS AND METHODS FOR PERFORMING TONSILLECTOMY, ADENOIDECTOMY, AND OTHER SURGICAL PROCEDURES
First Claim
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.

Abstract
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.

9. A method of using a surgical instrument, comprising:
-
selecting a grasping configuration from between at least a first grasping configuration and a second gasping configuration; if the first grasping configuration is selected, grasping a surgical instrument such that a user'"'"'s thumb is disposed within a waist defined atop a housing of the surgical instrument, a user'"'"'s index finger is partially received within a saddle of a trigger of the surgical instrument, a user'"'"'s middle finger is partially received within a finger-retaining area defined atop a movable handle of the surgical instrument, and a user'"'"'s ring finger and pinky are positioned adjacent a grasping surface of the movable handle; and if the second grasping configuration is selected, grasping the surgical instrument such that the user'"'"'s pinky is partially received within the saddle of the trigger, the user'"'"'s ring finger is partially received within the finger-retaining area of the movable handle, and the user'"'"'s middle finger and index finger are positioned adjacent the grasping surface of the movable handle. - View Dependent Claims (10, 11, 12, 13, 14)
