Abstract
The invention relates to a double focusing apparatus of an ultrasound tumor-treating system which comprises a ball-crown body, an ultrasonic power source and an ultrasonic piezoelectric transducer. The ultrasonic power source is connected with the ultrasonic piezoelectric transducer which comprises a piezoelectric wafer provided with a concave head face. The apparatus is characterized in that at least one mounting hole is arranged on the ball-crown body; one part of the ultrasonic piezoelectric transducer is arranged in the mounting hole, and the concave head face of the piezoelectric wafer thereof is arranged outside the mounting hole. The concave head face of the piezoelectric wafer is arranged outside the mounting hole, the curvature radius of the concave head face of the piezoelectric wafer is limited to be larger than that of the ball-crown body so as to lead the ultrasonic that is sent by the ultrasonic piezoelectric transducer to be point-focused really, so that the disadvantage of a biggish focal spot formed by the ultrasonic focusing by using the double focusing apparatus of the prior art is overcome.
Description
Technical field
The present invention relates to the ultrasound wave focusing arrangement, be specifically related to a kind of High Intensity Focused Ultrasound tumor therapeutic system doubling focusing apparatus.
Background technology
The doubling focusing apparatus of the High Intensity Focused Ultrasound system of tumor treatment of prior art, comprise ball-crown body, ultrasonic power source and excess sound pressure electric transducer, the ultrasonic power source is connected with the excess sound pressure electric transducer, the excess sound pressure electric transducer comprises that one has the piezoelectric chip of spill end face, the electric wafer of excess sound pressure electric transducer is distributed in the installing hole of ball-crown body inwall, and its spill end face also is positioned at installing hole inside, ultrasonic power source forcing excess sound pressure electric transducer emission ultrasound wave, different excess sound pressure electric transducer ultrasonic waves transmitted focus on some point of ball-crown body front end by the inwall of ball-crown body, form focal spot, focal spot is more little, accumulative ultrasonic energy is big more in the unit area, helps the treatment of focus more.Ideal state is that different excess sound pressure electric transducer ultrasonic waves transmitted converge at a bit, and the therapeutic effect of this moment is best.But the focal spot that the doubling focusing apparatus of prior art forms is bigger, can not accomplish to make ultrasound wave to converge at a bit, therefore can not reach preferable therapeutic effect.The doubling focusing apparatus of prior art is demanded urgently improving.
As shown in Figure 1, the doubling focusing apparatus of prior art comprises ball-crown body 101 and piezoquartz 102, and piezoquartz 102 places the inside of hat body 101 installing holes fully, so the focal spot that ultrasound wave focusing forms is bigger.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of ultrasound tumor therapeutic system doubling focusing apparatus, and the doubling focusing apparatus that overcomes prior art is bigger by the focal spot that ultrasound wave focusing forms, and ultrasound wave can not really converge at the defective of a bit.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be:
A kind of ultrasound tumor therapeutic system doubling focusing apparatus, comprise ball-crown body, ultrasonic power source and excess sound pressure electric transducer, the ultrasonic power source is connected with the excess sound pressure electric transducer, the excess sound pressure electric transducer comprises that one has the piezoelectric chip of spill end face, at least one installing hole is set on ball-crown body, the part of described excess sound pressure electric transducer places in the described installing hole, and the spill end face of its piezoelectric chip places the outside of described installing hole.
Described ultrasound tumor therapeutic system doubling focusing apparatus, wherein: described spill end face is made as the curved surface of rule.
Described ultrasound tumor therapeutic system doubling focusing apparatus, wherein: the radius of curvature of the described spill end face of piezoelectric chip is greater than the radius of curvature of described ball-crown body.
Described ultrasound tumor therapeutic system doubling focusing apparatus, wherein: the radius of curvature R r of spill end face and the radius of curvature R of ball-crown body satisfy following relational expression:
Wherein:
Beneficial effect of the present invention is: because the present invention places the spill end face of piezoelectric chip the outside of ball-crown body installing hole, and the radius of curvature of the spill end face of qualification piezoelectric chip is greater than the radius of curvature of ball-crown body, make the piezoelectric transducer ultrasonic waves transmitted really to focus on a bit, overcome prior art doubling focusing apparatus ultrasound wave and focused on the bigger defective of focal spot that forms.

Fig. 1 is a prior art doubling focusing apparatus structural representation;
Fig. 2 is a doubling focusing apparatus structural representation of the present invention;
Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
The specific embodiment
With embodiment the present invention is described in further detail with reference to the accompanying drawings below:
As shown in Figures 2 and 3, doubling focusing apparatus of the present invention comprises that the inner wall surface radius of curvature is 1, eight excess sound pressure electric transducer 2 of ball-crown body of R, and the part of excess sound pressure electric transducer 2 is installed in the installing hole of ball-crown body.Excess sound pressure electric transducer 2 comprises piezoelectric chip, the spill end face 21 of piezoelectric chip places the outside of the installing hole of ball-crown body, wherein spill end face 21 is the curved surface of rule, its radius of curvature is Rr, and Rr is greater than R, under the excitation in ultrasonic power source, the excess sound pressure electric transducer sends ultrasound wave, and converges in from a bit for Ra of center wafer point distance.
The radius of curvature R r of spill end face and the radius of curvature R of ball-crown body satisfy following relational expression:
Wherein:
λ is the ultrasound wave wavelength, and a is the radius of spill end face.
Those skilled in the art do not break away from essence of the present invention and spirit, can there be the various deformation scheme to realize the present invention, the above only is the preferable feasible embodiment of the present invention, be not so limit to interest field of the present invention, the equivalent structure that all utilizations description of the present invention and accompanying drawing content are done changes, and all is contained within the interest field of the present invention.
