A surgical instrument includes an elongate tubular member, an end effector at the distal end of the tubular member, a linkage rod slidably disposed within the tubular member, a distal connector fixed to the proximal end of the tubular member, a proximal connector fixed to the proximal end of the linkage rod, at least one resiliently flexible actuating member, and a lever pivotally to the proximal connector. The lever generally overlies and contacts the actuator member. Pivoting of the lever toward the flexible actuator member causes the linkage rod to move a movable jaw of the end effector. The surgical instrument has a relatively larger actuator surface for easier manipulation, and better balance. The actuator member also has a point of maximum leverage closer to the distal end, than other surgical instruments of the same general type.
