摘要： A method for calculating the capacitance of a transducer (C0) without knowing the exact resonance frequency of a transducer/blade combination is achieved by sweeping across a broad frequency range which contains resonant and non-resonant frequencies where C0 can be measured. A pre-defined frequency range is set independently of the resonance frequency of a specific transducer/blade combination. C0 of the transducer/blade is measured at several different frequencies within the pre-defined frequency range to ensure that invalid C0 measurements are disregarded, and the temperature of the transducer is calculated based on valid C0 measurements. The determined transducer temperature, based on C0 measurements, can be used to optimize performance and/or provide a safety shutdown mechanism for the generator.

摘要： A surgical device. The surgical device may comprise a transducer, an end effector, a generator and a control circuit. The transducer may be configured to provide vibrations. The end effector may be coupled to the transducer and may extend from the transducer along the longitudinal axis. The generator may provide an electrical signal to the transducer. Also, the control circuit may modify a current amplitude of the electrical signal in response to a change in a vibration frequency of the end effector. Accordingly to various embodiments, the control circuit may detect a first contribution to a vibration frequency of the end effector, the first contribution originating from tissue in contact with the end effector. Also, according to various embodiments, the control circuit may indicate a change in a vibration frequency of the end effector.

摘要： An apparatus includes an end effector, an energy component, a control module, and a directional force sensor assembly associated with the energy component and control module. The directional force assembly can include a piezoelectric disc, a piezoresistive element, an accelerometer, and/or a Hall Effect sensor. The end effector of the apparatus can include ultrasonic blade, an RF electrode, or a staple driving assembly. In some versions, the energy component includes an ultrasonic transducer. The control module may be configured to operate the energy component at a first energy setting in response to a first detected force and at a second energy setting in response to a second detected force. The apparatus may also include an activation feature to be operated by a user. In some versions the piezoelectric disc may include a plurality of segments and may be configured to induce movement in at least part of the energy component.
