Abstract: The present invention provides a focus ultrasonic wave source including an ultrasonic wave emitting component for emiting the ultrasonic wave and a focusing component for focusing the the emited ultrasonic wave, wherein the emitted ultrasonic wave is transmitted to a focal point in a manner similar to a spherical wave after it is focused by said focusing component, and wherein an angle ? included between the two lines connecting two end points of the outer peripheral diameter of said focusing component to the focal point respectively is from 50° to 120°.

Abstract: The present invention provides a containing means for receiving the transmission medium for use With an ultrasonic wave source of an extracorporeal HIFU therapeutic apparatus, wherein the containing means for transmission medium is a semispheric membrane with a seating arragnment on an upper open end thereof for sealing connecting the containing means to the ultrasonic wave source, so that the membrane closes the ultrasonic wave emitting surface. The membrane is made from a material with an acoustic impedance close to that of the water, lower ultrasound transmission loss, perfect heat conductivity and good elasticity, such as latex, natural rubber, silicon rubber etc. The containing means can be used in the case that the ultrasonic wave source is mounted above the bed surface. It is easy to make the ultrasonic wave source rotated and tilted so that the inclining angle of the ultrasonic wave source may be adjusted as required so as to adapt to the variety of treatment requirements.

Abstract: The present invention provides an extracorporeal HIFU therapeutic apparatus including a HIFU source and a driving circuit thereof for providing HIFU; a locating system for searching the object to be treated and moving it to the focal point of the ultrasound transducer, which includes a medical imaging system, a carrying device for the patient, and a displacement system for causing the spatial movement of the carrying device with respect to the HIFU source; and a high intensity ultrasonic wave transmitter and a processing system for the transmission medium, the ultrasonic wave adapted to the HIFU being transmitted into the patient body through a transmission medium; a container for receiving the transmission medium in front of an emitting surface of the HIFU source and means for filling, discharging and processing the transmission medium, wherein the HIFU source is supported on a supporting means and is placed above the carrying device so as to form an upper-mounted ultrasonic wave source.

Abstract: the present invention provides a seat frame for use with an extracorporeal HIFU therapeutic apparatus, in which the HIFU therapeutic apparatus includes a HIFU source for providing HIFU; a carrying device for patient and a displacement system for causing the spatial movement of the carrying device for patient with respect to the HIFU source, a containing means for receiving the transmission medium in front of an emiting surface of the HIFU source, said containing means for the transmission medium is an open-type water tank, wherein said seat frame includes a cushion which may be submerged in said open-type water tank, in said cushion is provided an arrangement through which the power ultrasonic wave may pass, said seat frame further includes a cushion supporting arrangement for supporting said cushion on said carrying device for patient.
