Fig. 1 is the sectional view that the high-intensity focusing ultrasonic wave (HIFU) illustrated according to illustrative embodiments treats head.Fig. 2 is the sectional view of the state illustrated before ultrasonic wave transmission medium is filled in accommodation space in FIG.
See figures.1.and.2, HIFU treats head and comprises HIFU transducer 110, housing 120, film 130 and film phonograph seal parts 140.
The HIFU being used for patient treatment launched by HIFU transducer 110.HIFU transducer 110 can have Ultrasonic Radiation surface 110a, and this Ultrasonic Radiation surface 110a is positioned at the lower end of HIFU transducer 110.Such as, HIFU transducer 110 can comprise supersonic generator 111 and Ultrasonic Radiation framework 116.Supersonic generator 111 can be arranged on Ultrasonic Radiation framework 116.Although not shown herein, supersonic generator 111 can be electrically connected to drive circuit board by electric wire etc.
Supersonic generator 111 can comprise piezoelectric element, and this piezoelectric element produces ultrasound wave by the resonance when voltage is applied by drive circuit board.Piezoelectric element can be made up of following: based on the piezoelectric ceramics of lead zirconate titanate (PZT), monocrystalline, the composite piezoelectric material etc. that these materials and polymeric material combined.In addition, supersonic generator 111 can comprise acoustic matching layer, and this acoustic matching layer is positioned on the side of piezoelectric element, suitably to mate resonance characteristics.Supersonic generator 111 is not limited to this illustrative embodiments, and reason is that supersonic generator 111 can construct in every way, as long as it can produce high-strength ultrasonic.
Ultrasonic Radiation framework 116 is by focusing on the high-strength ultrasonic produced by supersonic generator 111 and launching ultrasound wave.Ultrasonic Radiation framework 116 can have uniform thickness, and wherein, the center of this Ultrasonic Radiation framework 116 raises up.The lower surface of Ultrasonic Radiation framework 116 is Ultrasonic Radiation surface 110a.
Housing 120 at the accommodating HIFU transducer 110 of lower opening, with expose Ultrasonic Radiation surface 110a.Housing 120 can be formed as the cylindrical shape with inner space and unlimited lower end.The under shed of housing 120 can be closed because the edge of Ultrasonic Radiation framework 116 is attached to the under shed of housing 120.
Film 130 surrounds under shed and the excircle of housing 120, to form the accommodation space 131 of the ultrasonic wave transmission medium 101 be contained between film 130 and Ultrasonic Radiation surface 110a.Such as, film 130 can have cylindrical hollow portion and open upper.Film 130 can connect with the bottom of housing 120 in the mode of the under shed and excircle that surround housing 120.Ultrasonic wave transmission medium 101 can be made up of de aerated water etc.
Film 130 contacts with the excircle of housing 120.When ultrasonic wave transmission medium 101 is not contained in accommodation space 131, film 130 can be formed as shape as illustrated in Figure 2.Then, as shown in fig. 1, when the ultrasonic wave transmission medium 101 of scheduled volume is filled in accommodation space 131, the part of the under shed of the encirclement housing 120 of film 130 can be suitable near hemispherical shape.
Film 130 can be made up of following material: this material has the acoustic impedance similar with ultrasonic wave transmission medium 101, has low transmission loss, and has excellent elasticity.Such as, film 130 can be made up of the material of such as ethylene propylene diene monomer (EPDM) rubber, latex rubber, silicone rubber etc. and so on.
In addition, film 130 can have the thicker compared with the part of the under shed surrounding housing 120, and this thicker surrounds the excircle of housing 120.Therefore, when film 130 surrounds the excircle of housing 120, film 130 can remain firm shape.To seal the space between film 130 and housing 120 on the excircle that film phonograph seal parts 140 are positioned at housing 120.Therefore, ultrasonic wave transmission medium 101 can be prevented---be filled in film 130 and Ultrasonic Radiation surface 110a between---the connection part place between film 130 and housing 120 leaks.
As mentioned above, film 130 extends to the excircle surrounding housing 120 from the part of the under shed surrounding housing 120, and to cover Ultrasonic Radiation surface 110a, and the part of surrounding the excircle of housing 120 is sealed by film phonograph seal parts 140 with housing 120.Then, when when pressure is applied to ultrasonic wave transmission medium 101 while, the low portion of film 130 is pressed, pressure can distribute around film 130, thus improves sealing effectiveness.
In addition, compared with being sealed in the situation on the edge of Ultrasonic Radiation surface 110a with film 130, the distance moving to the sealing the excircle being positioned at housing 120 may be longer for ultrasonic wave transmission medium---this ultrasonic wave transmission medium is from ovfl of Ultrasonic Radiation surface 110a---.Therefore, even if when excessive pressure is applied to ultrasonic wave transmission medium 101 simultaneously film 130 contacts with the skin of the patient carrying out HIFU treatment, the effect that the connection part place that prevents ultrasonic wave transmission medium 101 between film 130 and housing 120 leaks can be improved.
