The controller is configured to define a predetermined operational plan including positions of a procedure object over time, assign a desired time milestone for each position of the object in the predetermined operational plan, and automatically monitor progress of the procedure based at least in part upon one or more positions of the procedure object over time. The controller is further configured to compare the one or more positions with the desired time milestone, record data relating to an actual time for each position of the object compared with the desired time milestone, and use the data to provide a recommendation for a change to a future predetermined operational plan.Type: ApplicationFiled: July 25, 2019Publication date: December 19, 2019Applicant: MAKO Surgical Corp.Inventors: Rony Abovitz, Hyosig Kang

Publication number: 20190380794Abstract: A surgical robot system includes a robot. The robot includes a robot base and a robot arm coupled to the robot base. The robot also includes an end-effector coupled to the robot arm. The robot is configured to control movement of the end-effector to perform a surgical procedure. The robot also includes an inertial measurement unit coupled to the robot arm. The surgical robot system also includes camera that is configured to capture one or more pictures or videos used to determine a location of the end-effector. The inertial measurement unit is configured to capture one or more measurements used to determine the location of the end-effector when a view of the camera is occluded.Type: ApplicationFiled: June 5, 2019Publication date: December 19, 2019Inventors: Bessam Al Jewad, Thomas Calloway, Norbert Johnson, Neil R.

Publication number: 20190380796Abstract: Devices, systems, and methods are provided in which movement of a tool is controlled based on sensed parameters. In one embodiment, an electromechanical tool is provided having an instrument shaft and an end effector formed thereon. The electromechanical tool is configured to be mounted on an electromechanical arm, and the electromechanical tool is configured to move with or relative to the electromechanical arm and perform surgical functions. A controller is operatively coupled to the electromechanical arm and the electromechanical tool and is configured to retard advancement of the electromechanical tool toward a tissue surface based on a sensed amount of displacement of a tissue surface, a strain on the tissue of the patient, the temperature of the electromechanical tool, or the like.Type: ApplicationFiled: August 27, 2019Publication date: December 19, 2019Inventors: Chad E. Eckert, Jason L. Harris, Frederick E. Shelton, IV

Publication number: 20190380797Abstract: Medical instruments having a translatable spool are disclosed. In one aspect, a medical instrument configured for use with a robotic system includes an instrument base configured to couple to a robotic drive mechanism of the robotic system and an elongate shaft coupled to the instrument base. The elongate shaft has a distal end. The medical instrument also includes a pull wire fixedly coupled to the distal end of the elongate shaft, the pull wire being configured to actuate the elongate shaft, and a rotatable spool in the instrument base. The rotatable spool is configured to direct the pull wire to the elongate shaft at an angle. The rotatable spool is configured to translate in coordination with actuation of the elongate shaft to control the angle of the pull wire relative to the elongate shaft.Type: ApplicationFiled: August 29, 2019Publication date: December 19, 2019Inventors: Alan Yu, Jason Lee

Publication number: 20190380798Abstract: A system comprises a medical tool including a shaft having proximal and distal ends and an articulatable distal portion coupled to the distal end of the shaft. The system also comprises a processing unit including one or more processors. The processing unit is configured to determine a target in a medical environment. The articulatable distal portion is directed toward the target. The processing unit is also configured to determine a motion of at least a portion of the shaft, and in response to the determined motion, control a pose of the articulatable distal portion so that the articulatable distal portion remains directed toward the target.Type: ApplicationFiled: March 7, 2018Publication date: December 19, 2019Inventors: Brandon D. Itkowitz, David W. Robinson
