    摘要： A rotatable fixation bridge as described herein may include a first end fixedly connectable to a reference and defining at least a portion of a first joint; a second end fixedly connectable to an anchor and defining at least a portion of a second joint; and a bridge member extending between and rotatably secured to the first end and the second end, the bridge member rotatable relative to an axis and comprising a central portion offset from the axis.

    摘要： Disclosed herein are systems and methods for a robotic arm guide used as a depth stop. For example, a system for positioning a surgical tool includes a surgical robotic system having a robot arm with a guide sleeve, the guide sleeve defining axial and lateral directions. The system is further configured to (i) receive a surgical plan associated with a subject, the surgical plan including three-dimensional preoperative data related to the subject, (ii) determine, based on the surgical plan, a desired trajectory of a distal end of the surgical tool as the surgical tool is inserted into the guide sleeve, and (iii) transmit one or more control signals to the surgical robotic system, causing the surgical robotic system to orient and position the guide sleeve such that the distal end of the surgical tool follows the desired trajectory when the surgical tool is inserted in the guide sleeve.

    摘要： 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.

    摘要： 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.
