Patent number: 11730389Abstract: A method for supporting medical interventions using an augmented reality system is disclosed, which comprises determining, using a position marker and an electronic tracking system, positions of a set of points; calculating a geometric shape using the determined positions of the set of points; and displaying, on an optical head mounted display the calculated geometric shape in the field of view of a bearer of the display. Furthermore, a system and a position marker adapted to be used for this method are disclosed.Type: GrantFiled: January 28, 2019Date of Patent: August 22, 2023Assignee: INCREMED AGInventors: Mazda Farshad, Till Bay, Simon Roner, Florentin Liebmann, Florian Wanivenhaus

Publication number: 20230245589Abstract: A computer implemented method of assisting bending of a reinforcing rod (10) includes the steps of receiving spatial positions (P1-n) of chirurgical implants (201-n), in particular pedicle screws, captured by a camera-based positioning device (50), the chirurgical implants (201-n) configured to attach to the reinforcing rod (10); calculating a rod shape (10c) corresponding to the spatial positions (P1-n), allowing the chirurgical implants (201n) to be attached to the reinforcing rod (10); based on the calculated rod shape (10c), calculating a sequence of bending parameter set(s); and generating tool operation guidance for bending tool(s) (70) based on the bending parameter set(s), the tool operation guidance indicating a sequence of prescribed operation steps (S1-n), wherein the sequence of prescribed operation steps (S1-n) are determined such, that when carried out using the bending tool(s) (70), causes the bending tool(s) (70) to shape the reinforcing rod (10) corresponding to the calculated rod shape (10c)Type: ApplicationFiled: December 9, 2022Publication date: August 3, 2023Applicant: 25SEGMENTS AGInventors: Philipp FÜRNSTAHL, Mazda Farshad, Marco Von Atzigen

Publication number: 20220398848Abstract: A method for monitoring and maintaining the sterility of objects in an operation room (1) is proposed, comprising: •registering target objects (3) and reference objects (4); •attributing to each target object (3) a set of reference objects (4); •attributing to each target object (3) a forbidden zone (90) and/or an allowed zone (91) based on a space occupied by the reference objects (4) attributed to this target object (3); tracking the target objects (3) and the reference objects (4); •determining, using data of the tracking, if a violation has occurred, the violation comprising that at least a part of a target object (3)—has entered the forbidden zone (90) attributed to that target object (3), and/or—has left the allowed zone (91) attributed to that target object (3). Furthermore, a surveillance system for performing this method is proposed.Type: ApplicationFiled: September 14, 2020Publication date: December 15, 2022Inventors: Till Bay, Andreas Pedroni, Mazda Farshad

Publication number: 20210378757Abstract: An augmented reality system for displaying a medical image (in particular an image stream) and a respective method are disclosed. The augmented reality system includes an optical head mounted display, a medical imaging device, a tracking system that is adapted to measure data concerning a position and orientation of at least one object, and a processing unit. The processing unit is configured to transform an image from a coordinate system in which the image was taken to a coordinate system of the display. This transformation is performed using data measured by the tracking system, where the ARS is adapted to display the transformed image on the display in a position, orientation and scale that corresponds to the perspective of a position and orientation of the bearer of the display.Type: ApplicationFiled: October 16, 2019Publication date: December 9, 2021Inventors: Till Bay, Christoph Krautz, Judith Gull, Ueli Peter, Samuel Hertig, Mazda Farshad

Patent number: 9439753Abstract: A graft anchor has first and second arms each having a leading end, a trailing end, an inner surface, and an outer bone contactable surface. The graft anchor also has a resilient bridge extending between the inner surface of the first arm and the inner surface of the second arm to space apart the first arm and the second arm. The resilient bridge defines a graft receiving pathway between the inner surfaces of the first and second arms. The resilient bridge also defines a deflection point about which a force acting upon the resilient bridge in a direction from the leading end to the trailing end causes the leading ends of the first and second arms to move toward one another and the trailing ends of the first and second arms to move away from one another.Type: GrantFiled: July 10, 2015Date of Patent: September 13, 2016Assignee: DePuy Synthes Products, Inc.Inventors: Nicolas Bouduban, Beat Lechmann, Patrick Burki, Jess Snedeker, Mazda Farshad
