ABSTRACT:
An ultrasound type treatment apparatus includes an inner sheath covering an ultrasonic transmission member having a first suction passage and defining a space relative to the ultrasound transmission member and an outer sheath covering the inner sheath and defining a space relative to the inner sheath. In the treatment apparatus, a liquid medium supply passage is provided at one of the space between the ultrasound transmission member and the inner sheath and space between the inner sheet and the outer sheet to supply a liquid medium to the distal end of the ultrasound transmission member. A second suction passage is formed at the other of the space between the ultrasound transmission means and the inner sheath and space between the inner sheath and the outer sheath. The first suction passage is connected by a suction tube to the second suction passage.
