変調器を備えた超音波手術器具
Document Type and Number:
Japanese Patent JP5687058
Kind Code:
B2
Abstract:
Methods for driving a surgical instrument are disclosed. The 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.
