Embodiment Construction

[0016] As described above, according to the structure of the present invention, it is possible to make an ultrasonic probe with excellent reliability, which can suppress the occurrence of a gap between the window and the frame and the accompanying liquid in the sound propagation medium even when the temperature changes. Leakage or air bubbles mixed in.

[0017] In the above-mentioned ultrasonic probe, in the above-mentioned window, it is preferable that the part where the above-mentioned metal part is embedded in the inside of the above-mentioned resin part is not simply a uniform flat plate shape, but has a through hole, a concave-convex structure, and is roughened, for example. parts, and bending parts, etc. According to this preferred example, the bond between the metal part and the resin part can be further strengthened, and the positional displacement, drop-off, etc. of the metal part can be suppressed.

[0018] In addition, in the ultrasonic probe described above, the w...

Abstract

In the ultrasonic probe in which the ultrasonic element unit and the ultrasonic propagation medium are stored in the storage unit formed by combining the window and the frame, it is possible to suppress the occurrence of a gap between the window and the frame when the temperature changes or the like. The ultrasonic probe of the present invention has: an ultrasonic element part (1) for transmitting and receiving ultrasonic waves, a frame (4) supporting the ultrasonic element part (1), and a window (5) combined with the frame (4) to surround the ultrasonic element part (1) , and the ultrasonic propagation medium filled in the space surrounded by the frame (4) and the window (5). The window (5) includes an ultrasonically transparent resin portion (5b), and a metal portion (5a) partially embedded in the resin portion (5b) and partially exposed to the outside of the resin portion (5b). The connection between the window (5) and the frame (4) is realized by bonding the part of the metal part (5a) exposed to the outside of the resin part (5b) to the frame (4).

Description

technical field [0001] The present invention relates to an ultrasonic probe used for, for example, medical ultrasonic diagnosis and the like. Background technique [0002] As an ultrasonic probe used in an ultrasonic diagnostic apparatus, there is known an ultrasonic probe in which an ultrasonic element portion for transmitting and receiving ultrasonic waves is rotated or oscillated in a storage portion enclosing an ultrasonic propagation medium having an acoustic impedance close to that of a living body. [0003] Figure 4 as well as Figure 5 It is a sectional view showing the structure of such a conventional ultrasonic probe. In these ultrasonic probes, the window 15 and the frame 14 are combined to form a storage unit, and the storage unit is filled with an ultrasonic propagation medium (not shown). In addition, an O-ring 16 is provided at the boundary between the window 15 and the frame 14 in order to prevent leakage of the medium. The ultrasonic element unit 11 and ...
