Publication number: 20190223961Abstract: A system for robot-assisted surgery includes an image sensor and a display. The system further includes a controller coupled to the image sensor and the display, where the controller includes logic that when executed by the controller causes the system to perform operations. The operations may include acquiring first images of a surgical procedure with the image sensor, and analyzing the first images with the controller to identify a surgical step in the surgical procedure. The operations may further include displaying second images on the display in response to identifying the surgical step; the second images may include at least one of a diagram of human anatomy, a preoperative image, an intraoperative image, or an annotated image of one of the first images.Type: ApplicationFiled: January 9, 2019Publication date: July 25, 2019Inventors: Joëlle K. Barral, Martin Habbecke, Xing Jin, Lin Yang

Publication number: 20190223962Abstract: A system and method of use thereof are provided for dynamically generating an environmental map for use in robotic assisted surgery. The generated environmental map is used to plan a recovery tool path that an end-effector tool can safely and efficiently follow to re-position the tool back to a cutting position following the displacement of the tool from the cutting position. Additionally, the environmental map is used to update a virtual representation of a bone to provide a user with visual feedback as to the progression of the end-effector tool as the tool removes material from the bone during a surgical procedure.Type: ApplicationFiled: January 17, 2019Publication date: July 25, 2019Inventors: Jay Roldan, Randall Hanson

Publication number: 20190223966Abstract: A computer-assisted teleoperated system includes a pre-load assembly in an instrument manipulator that is under the control of a controller. The controller can automatically cause the preload assembly to engage and disengage a preload. A surgical apparatus includes an instrument manipulator assembly and a sterile adapter assembly. The sterile adapter assembly is mounted in the distal face of the instrument manipulator assembly. When the preload assembly configures the instrument manipulator assembly to apply a preload force on the sterile adapter assembly, the sterile adapter assembly is removable from the distal face of the instrument manipulator. The sterile adapter assembly includes a mechanical sterile adapter assembly removal lockout and a mechanical instrument removal lockout.Type: ApplicationFiled: June 21, 2017Publication date: July 25, 2019Inventors: Robert E.

Publication number: 20190223967Abstract: A teleoperated manipulator system includes a manipulator assembly and a tool actuation assembly coupled to the manipulator assembly. The tool actuation assembly inserts a tool, such as a surgical instrument, along an insertion axis and also rotates the tool around the insertion axis. The manipulator assembly includes an arm that rotates with reference to amounting base to rotate the tool around a yaw axis that intersects the insertion axis. A distal portion of the arm defines an arcuate pitch arc, and a center of the pitch arc is coincident with the intersection of the insertion axis and the yaw axis. The tool actuation assembly is driven along the pitch arc to pitch the tool. The manipulator system is optionally a telesurgical system, and the tool is optionally a therapeutic, diagnostic, or imaging surgical instrument.Type: ApplicationFiled: October 4, 2017Publication date: July 25, 2019Inventors: Ryan Charles Abbott, Daniel H.
