Publication number: 20190142518Abstract: Robotic systems and methods for robotic arthroplasty. The robotic system includes a machining station and a guidance station. The guidance station tracks movement of various objects in the operating room, such as a surgical tool, a humerus of a patient, and a scapula of the patient. The guidance station tracks these objects for purposes of controlling movement of the surgical tool relative to virtual cutting boundaries or other virtual objects associated with the humerus and scapula to facilitate preparation of bone to receive a shoulder implant system. In some versions, planning for placement of a stemless implant component is based on a future location of a stemmed shoulder implant to be placed in the humerus during a revision surgery.Type: ApplicationFiled: November 6, 2018Publication date: May 16, 2019Applicant: MAKO Surgical Corp.Inventors: David Viscardi, Jan Heinsohn, Andrew Nelson, Phil Kemp, Rajan Yadav, Jetinder Singh, Koustubh Rao

Publication number: 20190142520Abstract: System and methods for simulating a surgical procedure are provided. The system includes a non-transitory computer-readable medium including instructions, which when executed by one or more processors, are configured to execute a surgical planning program. The surgical planning program is configured to track a tool relative to a model of an anatomy during a preoperative surgical simulation, generate a planning parameter based on the tracking of the tool relative to the model of the anatomy during the preoperative surgical simulation, and store the generated planning parameter. The system also includes a surgical system configured to load the generated planning parameter from the surgical planning program, and facilitate intraoperative surgery based on the generated parameter.Type: ApplicationFiled: November 12, 2018Publication date: May 16, 2019Applicant: Stryker CorporationInventor: Benjamin VanDyken
