Patent number: 10537441Abstract: Disclosed herein are systems and methods for bone preparation with designed areas having accurate tolerance profiles to enable improved initial fixation and stability for cementless implants and to improve long-term bone ingrowth/ongrowth to an implant. A method of preparing a bone surface to receive a prosthetic implant thereon having an articular surface and a bone contacting surface includes resecting the bone surface at a first location to create a first resected region having a first tolerance profile with a first cross-section, resecting the bone surface at a second location to create a second resected region having a second tolerance profile with a second cross-section less dense than the first cross-section, and contacting the bone contacting surface of the prosthetic implant with the first resected region.Type: GrantFiled: March 12, 2018Date of Patent: January 21, 2020Assignee: Stryker CorporationInventors: Stuart L.

Patent number: 10512509Abstract: Systems and methods for establishing and tracking virtual boundaries. The virtual boundaries can delineate zones in which an instrument is not permitted during a surgical procedure. The virtual boundaries can also delineate zones in which the surgical instrument is permitted during the surgical procedure. The virtual boundaries can also identify objects or structures to be treated by the instrument or to be avoided by the instrument during the surgical procedure.Type: GrantFiled: January 26, 2017Date of Patent: December 24, 2019Assignee: Stryker CorporationInventors: David Gene Bowling, Donald W.

Patent number: 10420619Abstract: A surgical manipulator operates in a manual mode in which a user applies forces and torques to the surgical instrument to cause movement of the energy applicator. The surgical manipulator also operates in a semi-autonomous mode in which the surgical manipulator moves the energy applicator along a tool path. A controller monitors output of a force/torque sensor as the energy applicator is being moved along the tool path in the semi-autonomous mode and transitions from the semi-autonomous mode to the manual mode in response to the output exceeding a limit.Type: GrantFiled: January 24, 2017Date of Patent: September 24, 2019Assignee: STRYKER CORPORATIONInventors: David Gene Bowling, John Michael Stuart, Joel N.

Publication number: 20190008596Abstract: A system includes a robotic manipulator comprising an arm and an end effector coupled to the arm and being moveable by the arm for interacting with a target site in a manual mode and an autonomous mode of operation. A navigation system is configured to track a position of the end effector and the target site. One or more controllers are configured to define a first virtual boundary relative to the target site, prevent the end effector from penetrating the first virtual boundary in the manual mode, and allow the end effector to penetrate the first virtual boundary in the autonomous mode.Type: ApplicationFiled: September 13, 2018Publication date: January 10, 2019Applicant: MAKO Surgical Corp.Inventors: David Gene Bowling, John Michael Stuart, Jerry A.

Patent number: 10098704Abstract: Surgical systems and methods for manipulating an anatomy with a tool include defining a first virtual boundary associated with the anatomy and a second virtual boundary associated with the anatomy. The first virtual boundary is activated in a first mode. Movement of the tool is constrained in relation to the first virtual boundary in the first mode. The first virtual boundary is deactivated in a second mode. Movement of the tool is constrained in relation to the second virtual boundary in the second mode.Type: GrantFiled: May 18, 2016Date of Patent: October 16, 2018Assignee: MAKO Surgical Corp.Inventors: David Gene Bowling, John Michael Stuart, Jerry A.

Patent number: 9921712Abstract: A system for providing substantially stable control of a surgical instrument is provided. The system includes a surgical manipulator for manipulating the surgical instrument and at least one computer configured to identify a first subset and a second subset of interaction geometric primitives associated with a virtual tool; determine, based on the first subset, control forces in a first subspace; and determine based on the second subset, control forces in a second subspace having at least one additional dimension. Control forces in the additional dimension are only determined based on the second subset of primitives, which is different than the first subset of primitives. The computer is further configured to determine a torque to constrain an orientation of the surgical instrument, wherein determining the torque comprises defining a virtual tool normal and a control plane normal and using the virtual tool normal and control plane normal to calculate the torque.Type: GrantFiled: March 6, 2017Date of Patent: March 20, 2018Assignee: MAKO Surgical Corp.Inventors: Christopher Alan Lightcap, Hyosig Kang, David Gene Bowling, John Michael Stuart, Jerry A.

Patent number: 9812035Abstract: Surgical systems and methods of demonstrating planned autonomous manipulation of an anatomy by a tool of a robotic surgical system include generating manipulation parameters representing planned constraints on autonomous manipulation of a volume of the anatomy by the tool in a first mode and generating demonstrative parameters relating to the manipulation parameters and defined in relation to a surface of the anatomy. The demonstrative parameters are less invasive to the anatomy than the manipulation parameters. The tool is moved in accordance with the demonstrative parameters in a second mode thereby demonstrating planned constraints on autonomous manipulation of the anatomy in relation to the surface of the anatomy.Type: GrantFiled: May 19, 2016Date of Patent: November 7, 2017Assignee: MAKO SURGICAL CORP.Inventors: John Michael Stuart, Jerry A.
