Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
302 words
An ultrasound type treatment apparatus comprising: ultrasonic oscillation means for generating an ultrasonic oscillation; amplifying means for amplifying the ultrasonic oscillation generated by the ultrasonic oscillation means; ultrasound transmission means, connected to a forward end of the amplifying means, and having a first suction passage therein; a cover member for covering an outer periphery of the ultrasound oscillation means; an inner sheath covering the ultrasound transmission means and defining a first space between the inner sheath and the ultrasound transmission means, the inner sheath having a base end portion thereof extending in a direction toward the ultrasonic oscillation means and a distal end portion thereof extending in a direction toward a distal end portion of the ultrasound transmission means; an outer sheath covering the inner sheath and defining a second space between the outer sheath and the inner sheath, the outer sheath having a base end portion extending in the direction toward the ultrasonic oscillation means and a distal end portion extending in the direction toward the distal end portion of the ultrasound transmission means; a liquid medium supply passage provided at one of the first and second spaces to supply a liquid medium to the distal end portion of the ultrasound transmission means; and diverting means for providing at least one of backing up and diverting at least a portion of the liquid medium in the liquid medium supply passage, said diverting means including: a second suction passage provided at the other one of the first and second spaces; and connecting means for connecting the first suction passage to the second suction passage to thereby provide a fluid flow path from the diverting means to the another end portion of the ultrasound transmission means to cool both the distal end portion and the another end portion of the ultrasound transmission means.
Claim 2
Dependent Claim
302 words
An ultrasound type treatment apparatus comprising: ultrasonic oscillation means for generating an ultrasonic oscillation; amplifying means for amplifying the ultrasonic oscillation generated by the ultrasonic oscillation means; ultrasound transmission means, connected to a forward end of the amplifying means, and having a first suction passage therein; a cover member for covering an outer periphery of the ultrasound oscillation means; an inner sheath covering the ultrasound transmission means and defining a first space between the inner sheath and the ultrasound transmission means, the inner sheath having a base end portion thereof extending in a direction toward the ultrasonic oscillation means and a distal end portion thereof extending in a direction toward a distal end portion of the ultrasound transmission means; an outer sheath covering the inner sheath and defining a second space between the outer sheath and the inner sheath, the outer sheath having a base end portion extending in the direction toward the ultrasonic oscillation means and a distal end portion extending in the direction toward the distal end portion of the ultrasound transmission means; a liquid medium supply passage provided at one of the first and second spaces to supply a liquid medium to the distal end portion of the ultrasound transmission means; and diverting means for providing at least one of backing up and diverting at least a portion of the liquid medium in the liquid medium supply passage, said diverting means including: a second suction passage provided at the other one of the first and second spaces; and connecting means for connecting the first suction passage to the second suction passage to thereby provide a fluid flow path from the diverting means to the another end portion of the ultrasound transmission means to cool both the distal end portion and the another end portion of the ultrasound transmission means.
