Patent number: 11937889Abstract: A robotic system and methods for performing spine surgery are disclosed. The system comprises a robotic manipulator with a tool to hold a screw and to rotate the screw about a rotational axis. The screw is self-tapping and has a known thread geometry that is stored by one or more controllers. A navigation system tracks a position of a target anatomy. Movement of the robotic manipulator is controlled to maintain the rotational axis of the surgical tool along a planned trajectory with respect to the target anatomy based on the tracked position of the target anatomy. In autonomous or manual modes of operation, the rotational rate of the screw about the rotational axis and/or an advancement rate of the screw linearly along the planned trajectory is controlled to be proportional to the known thread geometry stored in the memory.Type: GrantFiled: May 6, 2021Date of Patent: March 26, 2024Assignee: MAKO Surgical Corp.Inventors: Hyosig Kang, Jienan Ding, David Gene Bowling, Christopher Wayne Jones, Greg McEwan, Lucas Gsellman

Patent number: 11337766Abstract: Disclosed herein are techniques for preparation of a bone structure wherein a robotically controlled cutting bur is utilized for both milling the entry point at the outer cortical region and cannulation of the cancellous bone region for receipt of an implant. A robotic manipulator supports and moves the cutting bur and one or more controllers analyze measurements from sensors and, in response, control the robotic manipulator and/or the cutting bur for purposes such as landmark detection to determine entry point, avoiding tool skiving at entry point, and avoidance of cortical wall breach during cannulation. Also described are techniques for managing feed rate, rotational cutting speed, or mode of operation depending on operational conditions surrounding various stages of cannulation. A control interface is also provided to enable the user to manage or adjust cutting bur operation and feed rate.Type: GrantFiled: March 12, 2020Date of Patent: May 24, 2022Assignee: MAKO Surgical Corp.Inventors: Jamil Elbanna, Jienan Ding, Michael Prieto, Vijay Subramanian

Patent number: 10716630Abstract: A method for performing a revision surgery using a robotic-assisted surgery system includes determining information related to an interface area between an implant component and a bone, and generating a planned virtual boundary associated with a portion of the interface area to be removed in a representation of the implant and the bone, based at least in part on the information related to the interface area. The method further includes tracking movement in the physical space of a cutting tool such that movement of the cutting tool is correlated with movement of a virtual tool, and providing a constraint on the cutting tool while the cutting tool removes the portion of the interface area. The constraint is based on a relationship between the virtual tool and the planned virtual boundary. The portion of the interface area is removed to remove the implant component from the bone.Type: GrantFiled: July 13, 2017Date of Patent: July 21, 2020Assignee: MAKO Surgical Corp.Inventors: Viktor Krebs, Hyosig Kang, Snehal Kasodekar, Matt Harrow, Jienan Ding, Ta-Cheng Chang, Min Wu, Jean Gonzalez, Peter Ebbitt
