    摘要: A surgical instrument includes a transducer configured to produce vibrations along a longitudinal axis at a predetermined frequency. An end effector is adapted to couple to the transducer and extends along the longitudinal axis. The end effector includes a body having a proximal end and a distal end. The distal end is movable relative to the longitudinal axis by the vibrations produced by the transducer. A drive module is coupled to the transducer to generate a modulated drive signal. The distal end of the end effector is movable in response to the vibrations produced by the transducer in response to the modulated drive signal.

    摘要: A biopsy system having a lateral tissue access port includes an energy based tissue penetration system that can advantageously penetrate hard tumors, improve hemostasis, and provide greater tissue access. The energy based tissue penetration system has a vibrational member removeably disposed within the biopsy system, and a distal tip of the vibrational member extending from the biopsy system for tissue penetration. A sleeve is located between the vibrational member and the lateral access port to prevent tissue contact with the vibrational member through the lateral access port.

    摘要: An ultrasonic surgical blade, and an instrument, having a gain step. The blade body has, in any half wave length of the ultrasonic-surgical-blade body, a first vibration antinode, a vibration node, a second vibration antinode, and a gain step. The gain step is located between the second vibration antinode and the first vibration antinode. The gain step is spaced apart from the vibration node by a gain-step distance greater than 5% of the distance between the second vibration antinode and the first vibration antinode. The instrument includes the blade, a handpiece having an ultrasonic transducer, and an ultrasonic transmission rod whose proximal end is operatively connected to the ultrasonic transducer and whose distal end activates the blade. In one option, the first vibration antinode is the distal tip, and the gain step is located between the vibration node and the distal tip, resulting in an increased active length of the blade.

    摘要: A temperature monitoring device and/or method which control the tissue temperature at the end-effector of a therapeutic ultrasonic cutting and coagulating instrument as the tissue is being heated with ultrasonic vibrations from the end-effector. One or more temperature sensors are located at the end-effector, preferably on a clamping member. The temperature sensors measure the temperature of the tissue engaged by the end-effector either directly or indirectly. An alternate method and apparatus provides an electrical tissue impedance measure in combination with an ultrasonic cutting and coagulating instrument to provide active feedback control of an ultrasonic generator.

    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.
