摘要：
In a laser surgical apparatus having a laser oscillator operable to oscillate to produce a laser beam, and an optical path connected to the laser oscillator for transmission of the laser beam, a hand piece at the fore end of the optical path is equipped with a vibrator element comprised of a piezoelectric transducer, and the vibrator element applies a vibration to the hand piece.
