A surgical device, comprising: a handle configured to be held by a hand of an operator; a shaft portion coupled to the handle, the shaft portion defining a shaft longitudinal axis; an end effector supported on a distal end of the shaft portion so as to rotate and pivot relative to the shaft portion; a first drive shaft extending through the shaft portion and operatively connected to the end effector to effectuate a rotation of the end effector about the shaft longitudinal axis of the shaft portion; a second drive shaft extending through the shaft portion and operatively connected to the end effector to effectuate a pivoting of the end effector relative to the shaft longitudinal axis of the shaft portion; and a controller supported on the handle so as to be actuated by a thumb of the hand of the operator holding the handle, the controller including: a first rotatable member; and a second rotatable member; the first rotatable member being configured to rotate the first drive shaft in one of a first direction and a second direction upon a corresponding first direction and second direction rotation thereof to effectuate a corresponding first direction rotation and second direction rotation of the end effector relative to the shaft portion; and the second rotatable member being configured to rotate the second drive shaft in one of a first direction and a second direction upon a corresponding first direction and second direction rotation thereof to effectuate a corresponding first direction pivoting and second direction pivoting of the end effector relative to the shaft portion; characterized in that a rate of rotation of the end effector is commensurate in scope with a rate of rotation of the first rotatable member, and wherein a rate of pivoting of the end effector is commensurate in scope with a rate of rotation of the second rotatable member. a handle configured to be held by a hand of an operator; a shaft portion coupled to the handle, the shaft portion defining a shaft longitudinal axis; an end effector supported on a distal end of the shaft portion so as to rotate and pivot relative to the shaft portion; a first drive shaft extending through the shaft portion and operatively connected to the end effector to effectuate a rotation of the end effector about the shaft longitudinal axis of the shaft portion; a second drive shaft extending through the shaft portion and operatively connected to the end effector to effectuate a pivoting of the end effector relative to the shaft longitudinal axis of the shaft portion; and a controller supported on the handle so as to be actuated by a thumb of the hand of the operator holding the handle, the controller including: a first rotatable member; and a second rotatable member; the first rotatable member being configured to rotate the first drive shaft in one of a first direction and a second direction upon a corresponding first direction and second direction rotation thereof to effectuate a corresponding first direction rotation and second direction rotation of the end effector relative to the shaft portion; and the second rotatable member being configured to rotate the second drive shaft in one of a first direction and a second direction upon a corresponding first direction and second direction rotation thereof to effectuate a corresponding first direction pivoting and second direction pivoting of the end effector relative to the shaft portion; characterized in that a rate of rotation of the end effector is commensurate in scope with a rate of rotation of the first rotatable member, and wherein a rate of pivoting of the end effector is commensurate in scope with a rate of rotation of the second rotatable member. a first rotatable member; and a second rotatable member; the first rotatable member being configured to rotate the first drive shaft in one of a first direction and a second direction upon a corresponding first direction and second direction rotation thereof to effectuate a corresponding first direction rotation and second direction rotation of the end effector relative to the shaft portion; and the second rotatable member being configured to rotate the second drive shaft in one of a first direction and a second direction upon a corresponding first direction and second direction rotation thereof to effectuate a corresponding first direction pivoting and second direction pivoting of the end effector relative to the shaft portion; characterized in that a rate of rotation of the end effector is commensurate in scope with a rate of rotation of the first rotatable member, and wherein a rate of pivoting of the end effector is commensurate in scope with a rate of rotation of the second rotatable member.
