  • Publication number: 20230355298
    Abstract: The present disclosure relates to devices, systems and methods for calculating the amount of energy delivered to tissue during an electrosurgical treatment. The present disclosure provides for a power supply that supplies electrosurgical energy to an applicator via a radio frequency (RF) output stage, a memory that stores at least one energy quantification function that determines an amount of energy delivered to patient tissue by the applicator and a controller that controls the power supply based on a selected power setting and determines the amount of energy delivered to the patient tissue based on the energy quantification function and the selected power setting. The controller counts the energy delivered to the patient tissue based on the selected power setting and a duration of activation time of the applicator at the selected power setting and displays the energy delivered in Joules.

  • Publication number: 20230305668
    Abstract: A detector is shown for detecting manually applied pressure. A substrate defines a position of activation and electrodes are mounted on this substrate. A processing device is energized such that the electrodes are configured to identify a position of applied pressure by detecting a change in resistance in response to a first energizing signal received from the processing device. Furthermore, the electrodes are configured to confirm this position of applied pressure by detecting a change in capacitance in response to a second energizing signal received from the processing device. The electrodes comprise a first electrode located on an upper surface which detects the change in capacitance, and second and third electrodes which detect the change in resistance.

  • Publication number: 20230079881
    Abstract: The present disclosure is directed to devices, systems, and methods for sensing and discerning whether a distal portion of a fat grafting cannula or probe is disposed in fat tissue or muscle tissue during fat grafting procedures. In one aspect of the present disclosure, a fat grafting cannula or probe is provided including first and second electrodes. Each electrode is coupled to a circuit, e.g., disposed in an electrosurgical generator. During a fat grafting procedure, the electrodes contact patient tissue. Based on signals received from each electrode, the circuit is configured to determine whether a distal portion of the fat grafting cannula is disposed in a fat tissue or muscle tissue. If the circuit determines that the fat grafting cannula is disposed in muscle tissue, the surgeon operating the fat grafting cannula is alerted to ensure that processed fat is not injected into the muscle tissue of the patient.
