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： An ultrasonic surgical hand piece is caused to be driven with an output displacement that is correlated with the phase margin, which is the difference of the resonant frequency and the anti-resonant frequency of the hand piece. A frequency sweep is conducted to find the resonant frequency and the anti-resonant frequency for the hand piece. The resonant frequency is measured at a point during the frequency sweep where the impedance of the hand piece is at its minimum. The anti-resonant frequency is measured at a point during the frequency sweep where the impedance of the hand piece is at its maximum. Using a target or specific output displacement, a drive current is calculated based on the phase margin which is the difference between the resonant frequency and the anti-resonant frequency. The hand piece is caused to be driven with the output displacement, by accordingly controlling the current output from a generator console for driving the hand piece.

摘要： Apparatus and method to permit selective cutting and coagulation required in fine and delicate surgical procedures. The apparatus includes two body members having proximal ends and distal ends with jaw members located adjacent the body member's distal ends. The body members are joined at a pivot located adjacent to the first and second jaw members joining the first and second body members where the body members' rotation about the pivot defines a plane of rotation. The scissors are adapted for selective application of energy to at least one jaw member by a switch located in the plane of rotation.

摘要： Ultrasonic instruments, and particularly solid core ultrasonic instruments, are advantageous because they may be used to cut and/or coagulate organic tissue using energy in the form of mechanical vibrations transmitted to a surgical end-effector at ultrasonic frequencies. The present invention provides a surgical instrument including force feedback system, in a closed loop arrangement that modulates the force applied to tissue from a surgical instrument. A generator provides electrical energy to the surgical instrument and an electrical signal representative of the generator load. The surgical instrument includes a handle that includes an actuating lever, and an end-effector located at the distal end of the handle. A force responsive element is operatively coupled to the actuating lever and the end-effector, wherein the force responsive element is adapted to alter a force on the end-effector in response to the electrical signal from the generator.
