Patent number: 11910995Abstract: The application relates to the problem of navigating a surgical instrument (at 301, 311) towards a region-of-interest (at 312) in endoscopic surgery when an image (300) provided by the endoscope is obscured at least partly by obscuring matter (at 303), wherein the obscuring matter is a leaking body fluid, debris or smoke caused by ablation. To address this problem, a computer-implemented method is proposed, wherein, upon detecting that the image from the endoscope is at least partly obscured, a second image is determined based on a sequence of historic images and based on the current position and orientation of the endoscope. Furthermore, a virtual image (310) is generated based on the determined second image.Type: GrantFiled: July 10, 2020Date of Patent: February 27, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Bernardus Hendrikus Wilhelmus Hendriks, Caifeng Shan, Marco Lai, Robert Johannes Frederik Homan, Drazenko Babic

Publication number: 20230240758Abstract: The invention relates to a system (8) for assisting a user in placing a penetrating device in tissue like a pedicle screw (7) in a vertebra’s pedicle. The system generates a virtual view (20) from a penetrating device tip perspective within the tissue in the direction of a path (21) through a model of the tissue. The virtual view is generated based on tracking information indicating a pose of the penetrating device, the model and the path, wherein the virtual view is configured such that it indicates a direction in which the user should move the penetrating device while placing it in the tissue. For instance, it can show a virtual tunnel (801) which is arranged along the path. If a user like a surgeon is provided with such a virtual view, the user can position the penetrating device along the path with a significantly increased accuracy.Type: ApplicationFiled: June 29, 2021Publication date: August 3, 2023Inventors: JARICH WILLEM SPLIETHOFF, BERNARDUS HENDRIKUS WILHELMUS HENDRIKS, DRAZENKO BABIC, JOHANNEKE GERRIGJE GROEN, CHRISTIAN REICH, RONALDUS FREDERIK JOHANNES HOLTHUIZEN, ROBERT JOHANNES FREDERIK HOMAN
