Title: TRACKED SURGICAL TOOL WITH CONTROLLED EXTENSION
Abstract:
A system, device, and method for controlling operation of a surgical tool (214) during a surgical procedure are described. For example, the system includes a tool assembly (210) and a surgical system (100). The tool assembly includes a rotating tool (214) and a sleeve (212) for holding the rotating tool. The surgical system includes a navigation system (200) configured to track at least a portion of the rotating tool and determine position information for the rotating tool, an alignment module (222) configured to receive the position information and determine whether the rotating tool is in a proper position for drilling a hole into a target bone (240), a robotic control component (220) configured to actuate and advance the rotating tool if the rotating tool is in the proper position, and a monitor (226) configured to determine if the rotating tool is advancing into the target bone along a predetermined path.
