  • Publication number: 20250099163
    Abstract: An electrosurgical system includes an instrument, an RF energy generator, and two ground pads. The instrument includes an electrode and a conductive shield that is configured to collect a capacitive coupling current that is induced by the application of RF energy to tissue by the electrode. A first electrical lead couples the first ground pad with the ground return of the conductive shield and the generator. The ground return is configured to divert a first portion of the capacitive coupling current to the generator via the first electrical lead. A second electrical lead couples the second ground pad with the ground return of the conductive shield and the generator. The ground return is configured to divert a second portion of the capacitive coupling current to the generator via the second electrical lead. The first and second portions of the capacitive coupling current are substantially equal.

  • Patent number: 12254977
    Abstract: A computing device, such as a surgical hub, may obtain performance data associated with a device, such as a surgical device in an operation room. Based on the performance data, a computing device may identify a performance signature associated with the surgical device. A computing device may determine whether the surgical device is an original equipment manufacturer (OEM) device or a counterfeit device. A computing device may compare the operation data and/or the performance signature to data (e.g., data from a ML trained model) associated with OEM devices. Based on the comparison, a computing device may determine whether the operation data associated with the surgical device is within a normal operation parameter. If a computing device determines that the operation data outside of the normal operation parameter, the computing device may send a message to a health care professional.
