Publication number: 20240008933Abstract: Systems and methods for defining a relationship between a surgical object and a tracker coupled to the surgical object. A first optical sensor senses light in an infrared spectrum or a near-infrared spectrum. A second optical sensor senses light in a visible light spectrum. Controller(s) acquire one or more first images of the tracker from the first optical sensor and acquire one or more second images of the surgical object from the second optical sensor. The controller(s) recognize a pose of the tracker based on the one or more first image and recognize a geometry of the surgical object based on the one or more second images. The controller(s) correlate the recognized pose of the tracker and the recognized geometry of the surgical object to define a relationship between the tracker and the surgical object.Type: ApplicationFiled: September 20, 2023Publication date: January 11, 2024Applicant: MAKO Surgical Corp.Inventors: Jean Stawiaski, Fadi Ghanam, David Hofmann

Patent number: 11723726Abstract: Systems and methods to track objects within an operating room with a navigation system that includes an optical sensor including sensing elements and a controller in communication with the optical sensor. The controller controls the optical sensor to process a first quantity of the sensing elements to view a first region of interest. The object is tracked within the first region of interest with the optical sensor. The controller obtains data related to the object within the operating room. The data may include a type of the object and/or prior pose data of the object being tracked. Based on the data, the controller controls the optical sensor to process a second quantity of the sensing elements, different from the first quantity, to view a second region of interest different from the first region of interest. The object is tracked within the second region of interest with the optical sensor.Type: GrantFiled: October 25, 2022Date of Patent: August 15, 2023Assignee: MAKO Surgical Corp.Inventors: Jochen Breisacher, David Hofmann, Emeric Umbdenstock, Jonathan Morgan, Paul Hoekstra

Patent number: 11553970Abstract: A method, a controller, and a surgical hybrid navigation system for transferring a registration of three dimensional image data of a surgical object from a first to a second surgical navigation system are described. A first tracker that is detectable by a first detector of the first surgical navigation system is arranged in a fixed spatial relationship with the surgical object and a second tracker that is detectable by a second detector of the second surgical navigation system is arranged in a fixed spatial relationship with the surgical object. The method includes registering the three dimensional image data of the surgical object in a first coordinate system of the first surgical navigation system and determining a first position and orientation of the first tracker in the first coordinate system and a second position and orientation of the second tracker in a second coordinate system of the second surgical navigation system.Type: GrantFiled: March 6, 2020Date of Patent: January 17, 2023Assignee: Stryker European Holdings I, LLCInventors: Hans Schöpp, Florian Herrmann, David Hofmann, Udo Pfrengle, Fabian Riegelsberger
