Abstract
The present invention relates to a transducer for an ultrasonic tumour therapeutic instrument, which is composed of a spherical cap and piezoelectric crystals arranged at the inner surface of the spherical cap. A plurality of piezoelectric crystals are powered by a high-frequency signal source and have 800cm<2> to 1200cm<2> of ultra-large and ultrasonic emitting surface. When entering a human body, ultrasonic energy has an ultra-large incidence angle of 80 to 120 degrees; on the premise that the transducer has the same focal region and sound intensity as those of other equipment, the present invention greatly reduces the sound intensity of the ultrasonic energy on transmission paths of the skin and the tissue of a human body, and the ultrasonic wave energy is centralized on focus; thus, the present invention ensures that patients are treated by the therapeutic instrument without needing anesthesia articles and scalding the skin, and the patients do not feel pain.
Description
Technical field
The present invention relates to a kind of ultrasonic transducer, refer in particular to a kind of ultrasonic tumor machine transducer with overlarge area and super large angle of incidence.
Technical background
At present, the ultrasonic transducer of High Intensity Focused Ultrasound tumor-treating machine, ubiquity the little defective of the little and ultrasonic angle of incidence of ultrasonic emitting area, make emitted energy too concentrated, and make the energy perpendicular to acoustic energy transmission direction unit are is that the sound intensity is excessive, causes burning and pain of tissue on skin interface and the transmission path easily
Summary of the invention
The technical problem to be solved in the present invention is, provide the big and ultrasonic angle of incidence of a kind of ultrasonic emitting area big ultrasonic transducer, it is applied to the High Intensity Focused Ultrasound tumor-treating machine, can compare with miscellaneous equipment under the prerequisite with same burnt territory and sound intensity, reduce the sound intensity of ultrasonic energy on transmission path greatly, do not burnt with tissue on assurance skin interface, the transmission path and organ and eliminate patient's pain.
For reaching the technical scheme that this purpose takes be.A kind of ultrasonic tumor machine transducer comprises that internal diameter is spherical crown 1, piezoquartz 2, the high-frequency signal source 3 of R, crystal shell 4 and support.Symmetry offers several installing holes on the sphere of spherical crown 1, the piezoquartz 2 identical with installing hole quantity is separately fixed in the installing hole of spherical crown 1 by its shell 4, spherical crown 1 is supported on the support, the surface of piezoquartz 2 is a camber, the ultrasound wave incident angle of transducer is β, be connected with each piezoquartz 2 by lead respectively with piezoquartz 2 the same number of high-frequency signal sources 3, the number of installing hole of offering on the described spherical crown 1 and the corresponding piezoquartz of installing 2 is 20-50, and the radius of curvature of described piezoquartz 2 is identical with the radius of curvature of spherical crown 1.
The internal diameter R of spherical crown 1 is 15cm-50cm.
Transducer maximum incident angle degree 13 is 80 °-120 °.
The invention has the beneficial effects as follows: because the big and ultrasonic incident angle of ultrasonic emitting area of this ultrasonic transducer is big, it is applied to the High Intensity Focused Ultrasound tumor-treating machine, can be under the prerequisite of the same burnt territory and the sound intensity, greatly reduce ultrasonic energy human body skin and in-house sound intensity on transmission path, guaranteed killing to focus, the skin interface and the normal structure of human body are not burnt, under the prerequisite that need not anaesthetize, can eliminate patient's pain fully.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is done to describe in further detail.
Fig. 1 is a ultrasonic transducer vertical view of the present invention.
Fig. 2 is Figure 1A-A cutaway view.
