Publication number: 20240135519Abstract: Technologies for determining the accuracy of three-dimensional models include a device having circuitry to obtain two-dimensional images of an anatomical object (e.g., a bone of a human joint), to obtain a candidate three-dimensional model of the anatomical object, and to produce two-dimensional silhouettes of the candidate three-dimensional model. The circuitry is also to apply an edge detection algorithm to the two-dimensional images to produce corresponding edge images and to compare the two-dimensional silhouettes to the edge images to produce a score indicative of an accuracy of the candidate three-dimensional model.Type: ApplicationFiled: October 4, 2023Publication date: April 25, 2024Inventors: Shawnoah S.

Publication number: 20240081912Abstract: A model production device generates one or more contact bodies of a patient-specific surgical instrument model based on a parameterized model of a patient's bone. The parameterized model includes a predetermined number of polygons each having a predetermined position relative to the patient's anatomy. The parameterized model may be generated based on a three-dimensional model that was generated based on multiple images of the patient's bone. The model production device adds parametric fixed geometry to the patient-specific surgical instrument model based on the parameterized model and subtracts the three-dimensional model of the patient's bone from the patient-specific surgical instrument model. Each contacting body may be positioned at a high-confidence part of the parametric model, and the parametric fixed geometry may be positioned at a low-confidence part. A patient-specific surgical instrument may be manufactured based on the patient-specific surgical instrument model.Type: ApplicationFiled: November 17, 2023Publication date: March 14, 2024Inventors: Shawnoah S.

Patent number: 11925426Abstract: Systems, methods, and devices are disclosed for surgical instruments, systems, and methods for preventing skiving of a drilling instrument during a robotic or robot-assisted surgery are disclosed. In one embodiment, a scan of a patient's anatomy can be performed to produce a model of the bone to be drilled into and analysis of the surface can determine if the curvature is such that, if a target trajectory for a bore were followed, skiving of the drilling instrument is likely. If so, an alternate anti-skiving trajectory can be determined. The anti-skiving trajectory of a bore differs from the target trajectory by at least one of entry point, diameter, axis, or depth.Type: GrantFiled: July 16, 2021Date of Patent: March 12, 2024Assignee: DePuy Synthes Products, Inc.Inventors: William J Frasier, Robert Brik, Richard Patrick Courtis, Tarik Yardibi, Marc Puls, Matias De La Fuente Klein, Lukas Theisgen, Manuel Vossel, Klaus Radermacher

Patent number: 11883220Abstract: Technologies for determining the spatial orientation of input imagery to produce a three-dimensional model includes a device having circuitry to obtain two-dimensional images of an anatomical object (e.g., a bone of a human joint), to determine candidate values indicative of translation and rotation of the anatomical object in the two-dimensional images, and to produce, as a function of the obtained two-dimensional images and the candidate values, a candidate three-dimensional model of the anatomical object. The circuitry is also to determine a score indicative of an accuracy of the candidate three-dimensional model, to determine whether the score satisfies a threshold, and to produce, in response to a determination that the score satisfies the threshold, data indicating that the candidate three-dimensional model is an accurate representation of the anatomical object.Type: GrantFiled: October 4, 2021Date of Patent: January 30, 2024Assignee: DePuy Synthes Products, Inc.Inventors: Shawnoah S.
