In one example, a system to make sterile a non-sterile optical sensor for use in navigational guidance during surgery includes a sterile drape having an optically transparent window to drape the optical sensor in a sterile barrier and a sensor alignment mechanism. The alignment mechanism secures the sensor through the drape in alignment with the window without breaching the sterile barrier and facilitates adjustment of the orientation of the optical sensor. The optical sensor may be aligned to view a surgical site when the alignment mechanism, assembled with the sterile drape and optical sensor, is attached to a bone. The alignment mechanism may be a lockable ball joint and facilitate orientation of the sensor in at least two degrees of freedom. A quick connect mechanism may couple the alignment mechanism to the bone.Type: GrantFiled: February 13, 2023Date of Patent: November 28, 2023Assignee: Intellijoint Surgical Inc.Inventors: Armen Garo Bakirtzian, Andre Novomir Hladio, Richard Tyler Fanson, Eric Ryterski

Patent number: 11806083Abstract: A system includes a processor and an output device. The processor is configured to: (a) receive electrical signals indicative of measured positions of (i) one or more chest position sensors attached externally to a chest of a patient, and (ii) one or more back position sensors attached externally to a back of the patient; (b) compare between (i) a first shift between the measured positions and respective predefined positions of the one or more chest position sensors, and (ii) a second shift between the measured positions and respective predefined positions of the one or more back position sensors; and (c) produce an alert in response to detecting a discrepancy between the first and second shifts. The output device is configured to output the alert to a user.Type: GrantFiled: May 14, 2018Date of Patent: November 7, 2023Assignee: Biosense Webster (Israel) Ltd.Inventors: Shaul Haim Raz, Avigdor Rosenberg

Patent number: 11806084Abstract: Embodiments consistent with the present disclosure allow the ring, arc, and linear offset values for a stereotactic frame to be determined for a cranial procedure without requiring a CT scan to be acquired with the fiducial frame attached. Having the ring, arc, and offset values available for a cranial procedure allows the surgeon to revert to traditional stereotactic ring-arc frame guidance as a fallback strategy in case a robot cannot be used. This disclosure also provides an alternate method for registering a ring-arc system to the medical image volume for facilities having no CT scanner or scanner with limited field of view such that the intended fiducial localizer cannot be used.Type: GrantFiled: March 18, 2020Date of Patent: November 7, 2023Assignee: GLOBUS MEDICAL, INC.Inventors: Hayden Cameron, Spiros Mantzavinos, Neil R. Crawford

Patent number: 11800991Abstract: A method of guiding an interventional instrument within a patient anatomy comprises processing a target location within the patient anatomy and receiving a position for a tip portion of an interventional instrument at a first location within the patient anatomy. The method also comprises determining a three-dimensional distance between the first location and the target location and displaying a symbol representing the target location and a symbol representing the tip portion of the interventional instrument.Type: GrantFiled: August 12, 2014Date of Patent: October 31, 2023Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Vincent Duindam, Carol Reiley

Patent number: 11797103Abstract: This patent provides a method and apparatus for improving display of images of a virtual scene on an extended reality display. Specifically, this patent provides a method and apparatus to use different portions of the display based on a look angle of a user. For example, if a user looks at a nearby virtual object, more medially positioned portions of the display are utilized.Type: GrantFiled: July 8, 2021Date of Patent: October 24, 2023Inventors: Robert Edwin Douglas, Kathleen Mary Douglas, David Byron Douglas

Patent number: 11786221Abstract: A system for determining location of an interventional medical device within a patient includes a controller that controls an ultrasound probe to emit imaging beams at different times and angles relative to the ultrasound probe. The system also includes an interventional medical device with an attached sensor that receives the imaging beams together with repetitive noise. The controller further identifies the repetitive noise received at the sensor, including identifying the rate at which the repetitive noise is repeated and identifying the times at which the repetitive noise is received at the sensor. The controller further offsets the repetitive noise in signals received at the sensor by interpolating the signals based on the imaging beams. The controller determines the location of the interventional medical device based on the offset signals.Type: GrantFiled: April 2, 2019Date of Patent: October 17, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Ramon Erkamp, Alvin Chen, Shyam Bharat, Kunal Vaidya, Francois Guy Gerard Marie Vignon, Ameet Kumar Jain

Patent number: 11786318Abstract: A system for tracking an instrument includes two or more sensors (22) disposed along a length of an instrument and being spaced apart from adjacent sensors. An interpretation module (45) is configured to select and update an image slice from a three-dimensional image volume in accordance with positions of the two or more sensors. The three-dimensional image volume includes the positions two or more sensors with respect to a target in the volume. An image processing module (48) is configured to generate an overlay (80) indicating reference positions in the image slice. The reference positions include the positions of the two or more sensors and relative offsets from the image slice in a display to provide feedback for positioning and orienting the instrument.Type: GrantFiled: March 14, 2022Date of Patent: October 17, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Shyam Bharat, Ameet Kumar Jain, Antonio Bonillas Vaca

Patent number: 11786294Abstract: A surgical instrument comprising a housing, a shaft assembly, a processor, and a memory is disclosed. The shaft assembly is replaceably connected to the housing. The shaft assembly comprises an end effector. The memory is configured to store program instructions which, when executed from the memory cause the processor to send an electrical interrogation signal to the attached shaft assembly, receive a response signal from the attached shaft assembly, cause a default function to be performed when a response signal is not received by the attached shaft assembly, determine an identifying characteristic of the attached shaft assembly as a result of the performance of the default function, and modify a control program based on the identifying characteristic of the attached shaft assembly.Type: GrantFiled: May 28, 2020Date of Patent: October 17, 2023Assignee: Cilag GmbH InternationalInventors: Frederick E.
