Publication number: 20240407867Abstract: Surgical systems and methods involve a surgical robot and an end effector attached to the surgical robot. The end effector includes a drive assembly, a manual interface, a trigger assembly, and a tool attached to the drive assembly and being rotatable about a first axis. Controller(s) control the surgical robot to position the tool relative to a surgical site to align the first axis with a predetermined trajectory associated with the surgical site. The controller(s) detect input from the trigger assembly to rotate the tool about the first axis with the drive assembly and advance the tool along the predetermined trajectory at the surgical site to a first depth. The manual interface is configured to receive force to rotate the tool about the first axis and advance the tool along the predetermined trajectory to a second depth greater than the first depth.Type: ApplicationFiled: August 21, 2024Publication date: December 12, 2024Applicant: MAKO Surgical Corp.Inventors: Peter L. Ebbitt, Oscar Williams, Victor Soto, Hyosig Kang, Xiao H. Gao, Kana Nishimura, Ezra Johnson

Patent number: 11160620Abstract: End effectors for driving tools at surgical sites along trajectories maintained by surgical robots. A tool has interface and working ends. An end effector has a mount to attach to the surgical robot, and an actuator configured to generate torque. A drive assembly with a geartrain translates rotation from the actuator into rotation of a drive conduit supported about an axis. A rotational lock operatively attached to the drive conduit releasably secures the tool for concurrent rotation about the axis, and an axial lock releasably secures the tool for concurrent translation with the drive conduit along the trajectory maintained by the surgical robot. The axial lock is operable between a release configuration where relative movement between the drive assembly and the tool is permitted along the axis, and a lock configuration where relative movement between the drive assembly and the tool is restricted along the axis.Type: GrantFiled: January 25, 2019Date of Patent: November 2, 2021Assignee: MAKO Surgical Corp.Inventors: Peter L.
