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.

  • Publication number: 20250090220
    Abstract: Aspects of the present disclosure are presented for a medical instrument configured to adjust the power level for sealing procedures to account for changes in tissue impedance levels over time. In some aspects, a medical instrument may be configured to apply power according to a power algorithm to seal tissue by applying a gradually lower amount of power over to time as the tissue impedance level begins to rise out of the “bathtub region,” which is the time period during energy application where the tissue impedance is low enough for electrosurgical energy to be effective for sealing tissue. In some aspects, the power is then cut once the tissue impedance level exceeds the “bathtub region.” By gradually reducing the power, a balance is achieved between still applying an effective level of power for sealing and prolonging the time in which the tissue impedance remains in the “bathtub region.

  • 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.
