  • Surgical instrument with offset jaw actuator
    Patent number: 5989277
    Abstract: A tool for grasping or cutting with an offset jaw actuator is shown. The offset provides a consistent width to the actuator discouraging buckling under heavy loading situations. The offset also provides for greater contact area between the actuator and inner tip. The interface of the actuator with the inner tip is machined into the inner tip from the side resulting in an instrument that is easier and cheaper to manufacture and clean while retaining maximum strength for cutting or grasping.
