Patent number: 12272017Abstract: A method of generating a custom three-dimensional (3D) model of a patient bone from one or more 2D images is disclosed. The method includes obtaining a 2D image of a bone, optionally of a joint, and identifying a 3D bone template for a candidate or representative bone from a pre-aligned library of representative bones. The method further includes repositioning one or more views of the 3D model or 2D images (e.g., with respect to rotation angle or caudal angle). In an iterative process, another 3D bone model for another candidate bone can be identified based on the repositioning until an accuracy threshold is satisfied. When the accuracy threshold is satisfied, surface region(s) of the current 3D bone model can then be modified to generate the resulting 3D model for the patient bone. The process can then be repeated for other bone(s) associated with the joint of the patient.Type: GrantFiled: December 21, 2020Date of Patent: April 8, 2025Assignees: Smith & Nephew Orthopaedics AG, Smith & Nephew Asia Pacific Pte.

Patent number: 12268577Abstract: Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a driving circuit that supplies a driving signal to a negative pressure source to cause the negative pressure source to provide negative pressure via a fluid flow path to a wound dressing. The apparatus furthers include a controller that adjusts a frequency of the driving signal supplied by the driving circuit according to a comparison of a previous magnitude and a subsequent magnitude of the driving signal while the negative pressure source provides negative pressure. The transfer of power to the negative pressure source can thereby be tuned to maximize an amount of power transferred to the negative pressure source.Type: GrantFiled: November 15, 2021Date of Patent: April 8, 2025Assignee: Smith & Nephew PLCInventors: Ben Alan Askem, Victoria Beadle, John Philip Gowans, Mark Hesketh, Allan Kenneth Frazer Grugeon Hunt, William Kelbie, Damyn Musgrave, Joseph William Robinson
