Publication number: 20240225753Abstract: Methods, non-transitory computer readable media, surgical tracking devices, and systems that facilitate improved tracking in surgical environments are disclosed. With this technology, a fiber optic shape sensing (FOSS) device is rigidly attached to patient anatomy and/or surgical instrument(s) to facilitate location and/or flexibility tracking. The data provided by the FOSS device can be analyzed and registered to preoperative or intraoperative 3D anatomy model(s). The FOSS device can be attached to a surgical instrument to provide intraoperative guidance, used to locate a hollow needle for tracking bones in a minimally invasive manner, and/or used to detect bending in an instrument such as an arthroscope or tissue removing burr shaft, for example. The tracked location and/or flexibility data provided by the FOSS device can also be used to automatically control the location and/or operation of a surgical instrument during a surgical proceeding to facilitate improved surgical accuracy and patient outcomes.Type: ApplicationFiled: February 20, 2024Publication date: July 11, 2024Applicants: Smith & Nephew, Inc., Smith & Nephew Orthopaedics AG, Smith & Nephew Asia Pacific Pte.

Publication number: 20240122671Abstract: Disclosed are systems and methods for a computerized framework that provides novel mechanisms for arthroscopic applications using real-time blood flow information. The disclosed framework operates by determining a real-time (or near real-time or substantially simultaneous) visualization of blood vessels or perfusion within anatomical structures during intraoperative procedures, and leveraging this determined information for the performance of an arthroscopic procedure. The disclosed framework can enable an arthroscopic camera to see blood flow and perfusion in tissues in real-time, which allows for differentiation of various parts of the anatomy that may otherwise be undetectable.Type: ApplicationFiled: April 27, 2022Publication date: April 18, 2024Applicants: Smith & Nephew, Inc., Smith & Nephew Orthopaedics AG, Smith & Nephew Asia Pacific Pte.

Publication number: 20240000513Abstract: Systems for fusing arthroscopic video data are described. A system comprises an arthroscopic assembly, an inertial measurement unit (IMU) mounted on the arthroscopic assembly, a processor, and a processor-readable storage medium. An arthroscopic surgical plan, images from the arthroscopic assembly, and measurements from the IMU may be obtained. The images and the measurements may be combined to form a data combination. The data combination may be filtered to form a fused data set. The fused data set may control a device. A map of an arthroscopic surgical site may be created based on the fused data set, and a position of the arthroscopic assembly with respect to the arthroscopic surgical site may be calculated. The arthroscopic surgical plan may be updated based on at least one of the map of the arthroscopic surgical site and the position of the arthroscopic assembly.Type: ApplicationFiled: January 21, 2022Publication date: January 4, 2024Applicants: Smith & Nephew, Inc., Smith & Nephew Orthopaedics AG, Smith & Nephew Asia Pacific Pte.

Publication number: 20230225822Abstract: Optical tracking of objects in arthroscopic surgery. Examples comprise a resection instrument system including: a handpiece; a mechanical resection device comprising a stationary outer hub, an elongate outer tube coupled to and extending away from the stationary outer hub, and a cutter disposed at a distal end of the elongate shaft, the stationary outer hub coupled to the handpiece; a fiducial array; and a sleeve connector. The sleeve connector may include: a sleeve defining a distal end, a proximal end, and a through bore, the sleeve concentrically arranged with the elongate shaft; an array connector coupled to the proximal end of the sleeve, the array connector coupled to the fiducial array.Type: ApplicationFiled: June 30, 2021Publication date: July 20, 2023Applicants: SMITH & NEPHEW, INC., SMITH & NEPHEW ORTHOPAEDICS AG, SMITH & NEPHEW ASIA PACIFIC PTE.

Publication number: 20230210542Abstract: Treating femoroacetrabular impingement. At least one example is a method comprising: monitoring, by a procedure controller, location of a first member of an acetabulofemoral joint in a three-dimensional coordinate space; tracking, by the procedure controller, an amount of bone resected from the first member of the acetabulofemoral joint by tracking a distal end of a resection device in the three-dimensional coordinate space; and controlling, by the procedure controller, a rate of resection of the resection device based on the location of the distal end of the resection device relative to a planned resection volume associated the first member of the acetabulofemoral joint.Type: ApplicationFiled: June 29, 2021Publication date: July 6, 2023Applicants: SMITH & NEPHEW, INC., SMITH & NEPHEW ORTHOPAEDICS AG, SMITH & NEPHEW ASIA PACIFIC PTE.

Methods for Autoregistration of Arthroscopic Video Images to Preoperative Models and Devices Thereof
Publication number: 20230200928Abstract: Surgical methods and devices that facilitate registration of arthroscopic video to preoperative models are disclosed. With this technology, a machine learning model is applied to diagnostic video data captured via an arthroscope to identify an anatomical structure. An anatomical structure in a three-dimensional (3D) anatomical model is registered to the anatomical structure represented in the diagnostic video data. The 3D anatomical model is generated from preoperative image data. The anatomical structure is then tracked intraoperatively based on the registration and without requiring fixation of fiducial markers to the patient anatomy. A simulated projected view of the registered anatomical structure is generated from the 3D anatomical model based on a determined orientation of the arthroscope during capture of intraoperative video data. The simulated projected view is scaled and oriented based on one or more landmark features of the anatomical structure extracted from the intraoperative video data.Type: ApplicationFiled: June 16, 2021Publication date: June 29, 2023Applicants: SMITH & NEPHEW, INC., SMITH & NEPHEW ORTHOPAEDICS AG, SMITH & NEPHEW ASIA PACIFIC PTE.

Publication number: 20230065449Abstract: Systems and methods for performing an osteotomy with robotic assistance are disclosed. The disclosed systems and methods includes receiving a three-dimensional model of a patient bone, receiving a surgical plan, determining, based on the three-dimensional model and the surgical plan, one or more corrective cuts to be made to the patient bone, and performing, using a tracked end effector interfaced to a robotic arm, the one or more corrective cuts. A surgeon may utilize software, tracking, robotics, and the like to plan and execute bone resection in complex and/or intricate shapes not previously possible.Type: ApplicationFiled: February 4, 2021Publication date: March 2, 2023Inventors: Paul Alexander Torrie, Nathan Anil Netravali
