Patent number: 12217442Abstract: Systems and methods for performing registration between a patient space and an image space are disclosed herein. Systems using such methods may identify a pose of a registration frame having one or more apertures within the patient space using a tracking system. Image data corresponding to the image space having an image of the registration frame is taken. A plurality of aperture locations within the image data (corresponding to the apertures of the registration frame) are identified in the image data. Aperture representations from a model of the registration frame are matched to these aperture locations to determine a pose of the registration frame within the image space. A transform between the patient space and the image space is generated based on the pose of the registration frame within the patient space and the pose of the registration frame within the image space. Optimization methods for this transform are discussed.Type: GrantFiled: February 4, 2022Date of Patent: February 4, 2025Assignee: Medtronic Navigation, Inc.Inventors: Ryan D.

Publication number: 20240156470Abstract: A surgical device for cutting or shaving bone or tissue includes a housing having an elongated tube extending therefrom, the elongated tube configured to support a surgical tool at a distal end thereof. A gear assembly is disposed within the housing and is configured to control oscillation of the surgical tool. A motor is operably coupled to the housing and is configured to drive the gear assembly upon activation thereof. The motor is moveable relative to the housing to adjust one or more gears of the gear assembly which, in turn, adjusts an oscillation angle of the surgical tool to control the aggressiveness of the surgical tool when cutting tissue or bone.Type: ApplicationFiled: November 16, 2023Publication date: May 16, 2024Inventors: Milton F. Barnes, Haoran Li, Steven Hartmann

Publication number: 20220198665Abstract: Systems and methods for monitoring one or more anatomical elements are provided. An image depicting one or more anatomical elements and a plurality of annotations may be received. The image may comprise a plurality of image elements. Each annotation may correspond to one of the one or more anatomical elements and may be associated with one of the plurality of image elements. Movement information about movement of at least a portion of a particular anatomical element may be received. Image elements corresponding to the particular anatomical element may be identified to yield a set of image elements. The set of image elements may be adjusted based on the movement information to yield an updated image reflecting changes to affected anatomical elements.Type: ApplicationFiled: November 1, 2021Publication date: June 23, 2022Inventors: Nikhil Mahendra, Shai Ronen, Victor D.

Publication number: 20220183764Abstract: Systems and methods for correcting experienced EM fields measured at each of one or more EM trackers of an EM tracking system as such measurements are influenced by a known distorter are disclosed herein. An EM emitter may transmit an EM field such that it contains the one or more EM trackers. The system then determines a pose of a distorter within the EM field. The system receives, from each EM tracker, data representing experienced EM fields as distorted by a distortion field caused by the distorter. The system proceeds to determine the distortion field using the pose and a model comprising one or more characteristics of the distorter. The system may first optimize the model. The system calculates data representing corresponding corrected experienced EM fields based on each respective experienced EM field and the determined distortion field at the same location.Type: ApplicationFiled: November 15, 2021Publication date: June 16, 2022Inventors: Bradley W. Jacobsen, Victor D. Snyder, Robert Pahl, Andrew J. Wald, Steven Hartmann, Dominic M. Graziani

Patent number: 10444624Abstract: A thermal frame of an imprinting apparatus has an motor and a cooling element. A metrology frame of the imprinting apparatus is coupled to an output end of the motor and receives an imprinting mold. Thermal isolation is provided between the motor and the metrology frame. Thermal sensors are disposed at locations of the frames. A digital controller applies a control signal for controlling a driving signal of the cooling element to maintain a thermal balance, such as thermal equilibrium, of heat flow between the frames. The digital controller uses output of the thermal sensors to identify transfer functions of heat flow used to calculate the control signal. The feedforward design avoids the very low control bandwidth that limits the performance of typical feedback designs.Type: GrantFiled: November 30, 2018Date of Patent: October 15, 2019Assignee: Canon Kabushiki KaishaInventors: Xiaoming Lu, Byung-Jin Choi, Steven Hartmann

Publication number: 20060025677Abstract: A surgical navigation system for navigating a region of a patient that may include a non-invasive dynamic reference frame and/or fiducial marker, sensor tipped instruments, and isolator circuits. The dynamic reference frame may be placed on the patient in a precise location for guiding the instruments. The dynamic reference frames may be fixedly placed on the patient. Also the dynamic reference frames may be placed to allow generally natural movements of soft tissue relative to the dynamic reference frames. Also methods are provided to determine positions of the dynamic reference frames. Anatomical landmarks may be determined intra-operatively and without access to the anatomical structure.Type: ApplicationFiled: July 11, 2005Publication date: February 2, 2006Inventors: Laurent Verard, Joel Hughes, Steven Hartmann, John Kappus, Joseph Moctezuma, Matthew DiCorleto, Bradley Jascob, John Clayton
