  • METHODS AND ULTRASONIC DEVICES AND SYSTEMS FOR VESSEL SEALING
    Publication number: 20230277210
    Abstract: A method for sealing a vessel includes supplying electrical energy to an ultrasonic surgical instrument having an end effector and a transducer coupled to the end effector, when the end effector is grasping a vessel, sensing parameters of the vessel when the end effector achieves a predetermined velocity, estimating a size of the vessel based on the sensed parameters, controlling the electrical energy based on maintaining a predetermined initial heating rate of heating the vessel until a predetermined amount of energy corresponding to the estimated size of the vessel has been delivered, and controlling the electrical energy based on a predetermined heating rate curve of heating the vessel after the predetermined amount of energy corresponding to the estimated size of the vessel has been delivered.
    Type: Application

  • Methods and systems for ultrasonic vessel sealing
    Patent number: 11540856
    Abstract: A method includes providing electrical energy to a transducer for sealing a vessel, where a frequency of the electrical energy is in an ultrasound range, controlling the electrical energy to achieve a predetermined velocity of an end effector coupled to the transducer, when the end effector is grasping the vessel, sensing parameters of the electrical energy when the end effector achieves the predetermined velocity, calculating power of the electrical energy based on the sensed parameters and estimating a size range of the vessel based on the power, and controlling the electrical energy to achieve a target velocity, which is determined based on the estimated size range of the vessel, to seal the vessel.
