Abstract: An ultrasound apparatus of a body cavity insertable type includes: a handpiece; a supporting rod which is elongated from the handpiece; an ultrasound probe which is connected to the supporting rod and is configured to be able to be inserted in the body cavity; and a sealing cover which is separably coupled to the ultrasound probe to at least partially surround the ultrasound probe in a longitudinal direction from a distal end thereof. The ultrasound probe includes: a piezoelectric element; and a housing to which the piezoelectric element is mounted. An end of the housing is connected to the supporting, and the housing is provided with an ultrasound passing hole which is disposed outside the supporting rod. The sealing cover has an ultrasound passing window which is formed at a position corresponding to the ultrasound passing hole.

Abstract: An ultrasound apparatus of a body cavity insertable type includes: a handpiece; a supporting rod that is elongated from the handpiece; an ultrasound probe that includes a housing that is connected to the supporting rod and an ultrasound transducer that is fixed to the housing; and an ultrasound transmission medium circulation mechanism that is configured to discharge an ultrasound transmission medium filled in an ultrasound transmission space that is formed at a front of the ultrasound transducer and to inflow the discharged ultrasound transmission medium to the ultrasound transmission space again. The housing and the ultrasound transducer are configured such that the ultrasound transmission medium filled in the ultrasound transmission space is prevented from inflowing to a rear space of the ultrasound transducer.

Abstract: The present invention has been made in an effort to provide a line-focused ultrasound transducer and a high intensity line-focused ultrasound generation device including the same in which ultrasound is focused in a line so that the treatment time can be reduced and the structure can be simplified. A line-focused ultrasound transducer which focuses in a line shape includes: a therapeutic piezoelectric member having a hollow semi-cylindrical shape; a first electrode portion which is provided on an inner surface of the therapeutic piezoelectric member; and a second electrode portion which is provided on an outer surface of the therapeutic piezoelectric member in correspondence with the first electrode portion.

Abstract: An ultrasonic wave generating device includes: an ultrasonic transducer; and a variable pulse generating device which generates and outputs an electric pulse. The ultrasonic transducer comprises a piezoelectric element which receives electric pulse from the electric pulse generating device and vibrates, and a memory which stores characteristic information of the ultrasonic transducer.

Abstract: An apparatus for generating high intensity focused ultrasound includes: a housing which is filled with ultrasound transmitting medium; an ultrasound transducer which is movably disposed inside the housing; and a driving unit which linearly moves the ultrasound transducer.
