Abstract: Methods and systems for providing a safety mechanism for a robotically controlled surgical tool. Embodiments of the methods use sensors to detect parameters that vary by the tissue traversed by a surgical tool. The sensors detect signals arising from the interaction of the surgical tool with the tissue and provide this information to a robotic controller. For example, during drilling, the sensors may measure power, vibration, sound frequency, mechanical load, electrical impedance, and distance traversed according to preoperative measurements on a three-dimensional image set used for planning the tool trajectory. By comparing the detected output with that expected for the tool position based on the planned trajectory, identified discrepancies in output would indicate that the tool has veered from the planned trajectory. The robotic controller may then alter the tool trajectory, change the speed of the tool, or discontinue power to the tool, thereby preventing damage to underlying tissue.

Abstract: A method for determining a work volume includes receiving image information from an imaging device corresponding to an array of tracking markers fixed to a flexible mesh, the mesh placed over a patient and over at least one surgical instrument adjacent to or connected to the patient; determining a position of each tracking marker in the array of tracking markers based on the image information; defining a boundary for movement of a robotic arm based on determined tracking marker positions, such that the robotic arm does not contact the patient or the at least one surgical instrument during movement of the robotic arm; and controlling the robotic arm based on the defined boundary.

Abstract: A spinal stabilization system includes a plurality of anchors and at least one bridge. Each anchor includes a clamp configured to engage an anatomical element, the clamp movable between a fully open position and a fully closed position; a locking screw configured to selectively prevent the clamp from being moved into the fully open position; and a bridge interface. The at least one bridge is a rigid member having a first end and a second end opposite the first end, each of the first end and the second end having an anchor interface. The bridge interface is configured to receive the anchor interface.
