Publication number: 20240180580Abstract: Systems, devices, and methods are operable to track usage of a surgical instrument and modify the performance of the surgical instrument based on the prior usage of the surgical instrument. Some surgical instruments are designed to have a limited service life beginning at their first use, or a limit to their overall usage in order to ensure safe use of the sensitive instruments. However, a lack of ability to track usage characteristics when the instrument is separated from an external power supply allows for user abuse and avoidance of such safety mechanisms. Adding a battery or capacitor to the instrument may allow for an ability to track usage when the instrument is separated from an external power supply. Implementing special user prompts, device use ratios, and device use half-life upon powering down of an instrument may additionally be used to prevent circumvention of safety features.Type: ApplicationFiled: January 2, 2024Publication date: June 6, 2024Inventors: Craig N. Faller, Benjamin D. Dickerson, Jeffrey L. Aldridge, Jeffrey A. Bullock, Richard W. Timm, Ryan M. Asher, Timothy S. Holland, Craig T. Davis, Christina M. Hough, Cory G. Kimball, Ashvani K. Madan, David C. Yates, Shan Wan, Jacob S. Gee, Joseph E. Hollo, Chad P. Boudreaux, John B. Schulte, Tylor C. Muhlenkamp, Brian D. Black

Publication number: 20230372743Abstract: In one general aspect, various embodiments are directed to a surgical instrument that can supply mechanical energy and electrical energy to an end effector of the surgical instrument. The surgical instrument may be operated in a first operating mode in which a transducer of the surgical instrument produces mechanical energy, or vibrations, that are transmitted to the end effector and a second operating mode in which electrical energy, or current, can flow through the end effector to perform electrosurgery. In another general aspect, the surgical instrument may comprise a clamp, or jaw, which can be moved into a closed position to hold tissue against a waveguide, or blade, of the end effector. In the second operating mode of the surgical instrument, current can flow from a power source, through the waveguide, and return to the power source through a path comprising the jaw.Type: ApplicationFiled: May 24, 2023Publication date: November 23, 2023Inventors: Eitan T.

Publication number: 20230181263Abstract: A robotic system is integrated with the laparoscope effectively creating a 3D scanner which can be used during laparoscopic surgery. This enables advanced surgical navigation and visualization to aid with the surgical process. It also acts as a core data set to be used by the Digital Health Platform. This acts as the starting point for Virtual Reality reconstruction of the surgical procedure for both real time surgical guidance and advanced AI/ML development. Furthermore, diagnostic capabilities could also be integrated into the system to enable real time diagnostic data to be generated for use during the procedure. Coupling the diagnostic capabilities with the vision system of the laparoscope and the ground truth reference coordinate system of the robot enables quick Augmented Reality visualization through the Digital Health Platform.Type: ApplicationFiled: December 12, 2022Publication date: June 15, 2023Inventors: Brendan Reimer, Bin Zhao, Shan Wan

Publication number: 20230172684Abstract: This disclosure describes a video-based surgery analytics and quality/skills assessment system. The system takes surgery video as input and generates rich analytics on the surgery. Multiple features may be extracted from the video that describe operation quality and surgeon skills, such as time spent on each step of the surgery, medical device movement trajectory characteristics, and adverse events occurrence such as excessive bleeding. Description of the surgery, related to its difficulty such as patient characteristics, may be also utilized to reflect surgery difficulty. Considering the various extracted features and the surgery description provided by surgeon, a machine learning based model may be trained to assess surgery quality and surgeon skills, by weighing and combining those factors. The system may solve 2 challenges in objective and reliable assessment: differing level of surgery difficulty caused by patient uniqueness and balancing multiple factors that affect quality and skills assessment.Type: ApplicationFiled: December 5, 2022Publication date: June 8, 2023Inventors: Bin Zhao, Ning Li, Shan Wan
