Such surgical instruments may be directly gripped and manipulated by a surgeo n or incorporatedinto robotically assisted surgery. In the case of robotically assisted surgery, the surgeon may operate amaster controller to remotely contro l the motion of such surgical instruments at a surgical site. Thecontroller may be separated from the patient by a significant distance (e.g., across the opera ting room,in a different room, or in a completely different building than the p atient). Alternatively, a controller maybe positioned quite near the patient in the operating room. Regardless, the controller may include one ormore hand inp ut devices (such as joysticks, exoskeletol gloves, master manipulators, or the l ike), whichare coupled by a servo mechanism to the surgical instrument. In one example, a servo motor moves amanipulator supporting the surgical instrument ba sed on the surgeon’s manipulation of the hand inputdevices. During the surgery, the surgeon may employ, via a robotic surgical system, a variety of surgical instruments including an ultrasonic blade, a tissue grasper, a needle driver, an e lectrosurgical cautery probes, etc. Each of these structures performs functions for the surgeon, for example, cutting tissue, coagulatingtissue, holding or dri ving a needle, grasping a blood vessel, dissecting tissue, or cauterizing tissue .
