  • Publication number: 20150088122
    Abstract: A surgical system includes an end effector assembly, a motor assembly, an energy source, and a controller. The controller activates the motor assembly, once it is determined that tissue is present between jaw members of the end effector assembly, to move the jaw members from a spaced-apart position to an approximated position to grasp tissue. The controller further activates the energy source, once tissue is grasped between the jaw members, to supply energy to the jaw members to seal tissue grasped between the jaw members. The controller further activates the motor assembly, once it is determined that tissue sealing is complete, to move the jaw members from the approximated position to the spaced-apart position to release sealed tissue. The system may further be configured to cut tissue once it is determined that tissue sealing is complete but before moving the jaw members to the spaced-apart position.

  • Publication number: 20140002056
    Abstract: Systems and corresponding methods for determining characteristics of an output signal generated by a high-frequency medical device using low-frequency measurement systems are disclosed. A digital measurement system includes an oscillator, a mixer, and a controller coupled to each other. The oscillator provides a reference signal having a second frequency. The mixer generates a down-converted signal based on the output signal and the reference signal. The controller then determines a characteristic of the output signal (e.g., frequency or phase) based on the down-converted signal. An analog measurement system includes a filter having a center frequency, a rectifier, and a controller. The filter filters the output signal and the rectifier rectifies the filtered signal. The controller samples the rectified signal and determines a characteristic of the output signal based on the level of the rectified signal.
