Abstract
A surgical tool such as a grasper or a pair of surgical scissors includes a hinge portion that spans between a handle proximal portion and a distal working portion to communicate mechanical actions of the handle proximal portion to the distal working portion. A programmable rotary module is coupled to the hinge portion and includes a sensor, an actuator, and a controller. The sensor, actuator, and controller may be enclosed in a common housing. The sensor measures rotation of the distal working portion and the actuator generates haptic effects to the proximal handle portion. A controller is electrically connected to the sensor and to the actuator. The controller receives the rotation measurements from the sensor and, based upon the rotation measurements, outputs a control signal to the actuator relating to the generation of haptic effects. The haptic effects may include force sensations such as detents and barriers.
