Abstract
The utility model relates to a spherical crown type concave spherical-surface ultrasonic transducer, which comprises a concave spherical-surface piezoelectric ceramic sheet and an outer shell, wherein the concave spherical-surface piezoelectric ceramic sheet is a concave spherical-surface piezoelectric ceramic sheet in the shape of a spherical crown with uniform thickness; the concave spherical surface of the concave spherical-surface piezoelectric ceramic sheet is in a thin-shell structure; the piezoelectric ceramic sheet is arranged out of the outer shell, and is pressed and fixed with a helicoid by a pressure ring; the center of the piezoelectric ceramic sheet is provided with a circular hole capable of loading a probe. The ultrasonic transducer of the utility model is composed of the spherical crown type concave spherical-surface piezoelectric ceramic sheet and the outer shell. The center of the piezoelectric ceramic sheet is provided with a circular hole, so that the probe can be arranged in the circular hole. The outer shell and the pressure ring plays the role of fixation, which can prevent the back surface of the piezoelectric ceramic sheet from contacting with couple liquid. The adoption of the ultrasonic transducer of the utility model can avoid the defects in the prior art. The utility model can improve the ultrasonic focusing performance greatly. The focal point can be made smaller. Moreover, the loss of the sound wave is small.
Description
Technical field
This utility model relates to ultrasonic heater, particularly a kind of spherical cap type concave spherical surface ultrasonic transducer that adopts ultrasonic mode of heating treatment tumor.
Background technology
The ultrasonic tumor that heats to treat is a kind of effective method for treatment that development in recent years is got up.The ultrasound emission of this therapy equipment partly has various forms, as:
One, dull and stereotyped piezoelectric ceramic piece adds lens.
Two, be attached on the hardware of spherical cap type with some facet piezoelectric ceramic pieces, the normal of each piezoelectric ceramic piece is come together in a bit.
Three, several concave spherical surface piezoelectric ceramic pieces are divided into various piece and put together, and its each focus is converged at a bit.
More than three kinds of modes its merits and demerits is respectively arranged, wherein weak point is comparatively obvious.First kind of mode for example is because the effect of lens causes ultrasonic attenuation bigger.The ultrasound wave focus of the second way is bigger, and is difficult for concentrating.Though the third mode focus can be done lessly, the process of aiming at focus is comparatively complicated.
Summary of the invention
Task of the present utility model provides a kind of improved spherical cap type concave spherical surface ultrasonic transducer, and it has solved the lens problem and the ultrasound wave focal issue of prior art.
The technical solution of the utility model is as follows:
A kind of spherical cap type concave spherical surface ultrasonic transducer, it comprises concave spherical surface piezoelectric ceramic piece and shell, described concave spherical surface piezoelectric ceramic piece is the uniform concave spherical surface piezoelectric ceramic piece of spherical thickness, its concave spherical surface is a shell structure, piezoelectric ceramic piece is settled in the enclosure, and be fixed by pressure ring and bung flange, offer the circular hole that can adorn detector in the central authorities of piezoelectric ceramic piece.
Ultrasonic transducer of the present utility model is made of spherical cap type concave spherical surface piezoelectric ceramic piece and shell, and central authorities offer circular hole at piezoelectric ceramic piece, so that detector is installed; Shell and pressure ring have played fixation, can make the back side of piezoelectric ceramic piece avoid the contact of coupling liquid.
Adopt ultrasonic transducer of the present utility model to avoid the shortcoming of prior art, increased substantially hyperacoustic focusing performance, its focus can be done very for a short time, and the sound wave loss is little.
Description of drawings
Accompanying drawing is the structural representation of a kind of spherical cap type concave spherical surface ultrasonic transducer of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of spherical cap type concave spherical surface ultrasonic transducer of the present utility model is equipped with concave spherical surface piezoelectric ceramic piece and shell 2.The concave spherical surface piezoelectric ceramic piece is spherical concave spherical surface piezoelectric ceramic piece 1, and its thickness is even, and concave spherical surface is a shell structure, and its center of curvature promptly is a geometrical focus.
This spherical concave spherical surface piezoelectric ceramic piece 1 is placed in the shell 2, and is fixed by pressure ring 3 and bung flange 4.Bung flange 4 is pressed on piezoelectric ceramic piece 1 on the housing 2 by pressure ring 3, except the effect of playing fixing piezoelectric ceramic piece 1, also can prevent the back side of coupling liquid contact piezoelectric ceramic piece 1 like this.
Central authorities at piezoelectric ceramic piece 1 offer circular hole 5, so that detector is installed.
Spherical cap type concave spherical surface ultrasonic transducer of the present utility model is widely used in the ultrasonic tumor that heats to treat.
