BIPOLAR ULTRASONIC SURGERY |
摘要 |
An ultrasonic oscillator drives a tool at a set frequency. An amplitude control (47) runs the oscillator to set the vibration level. A frequency regulator (48) joins the amplitude and the oscillator. A handpiece supports a tranducer and a vibrating tool. A flue (17) surrounds the tool. Electrodes (42) associated with the flue (17) and/or the tool extend to be at or near the distal tip (18) of the tool and/or the flue (17) and provide bipolar electrosurgery with or without ultrasonic vibration of the tool. A method of performing ultrasonic surgery and bipolar electrosurgery has an ultrasonic handpiece with bipolar electrodes (42) associated with the tool or the flue (17).
