Abstract
A surgical instrument controller and actuating system that allows precise hand operated control of a powered instrument based on the detection of variations on the gripping force by means of pressure sensors located on the instrument handle. The grip pressure signal is processed by an electronic actuator controller which in turn drives an actuator system. The actuator system produces an actuation force that is proportional to the gripping force change detected at the instrument handle. The actuation force is transmitted to the active members of the instrument allowing precision proportional activation of surgical instruments such as micro forceps and micro scissors. The system allows an operator to precisely regulate the action of a surgical instrument by variation of the griping force applied over the handle of the instrument.
