Abstract
The utility model relates to a single probe of a transducer for a high-intensity focusing ultrasonic tumor therapeutic machine. The piezoelectric crystal which is installed in an annular shell is then reversely buckled and pressed by a clamping ring through an insulating pad, and a reflecting cavity is formed between the piezoelectric crystal and the clamping ring. The outer surface of the piezoelectric crystal is welded together with the shell by a grounding wire, and a high-frequency large-power signal source through is welded together with the inner surface of the piezoelectric crystal through a signal wire. The utility model can regularly reflect ultrasonic energy which is reversely transmitted, so that the reversely transmitted ultrasonic energy can be added with ultrasonic energy which is forwardly transmitted. The utility model improves the utilization efficiency of a transducer, reduced the heat loss of the transducer, saves a radiation device of the transducer, avoids the interference to an ultrasound field due to multiple reflection, refraction and diffusion, and enhances the therapeutic effects on foci of patients.
Description
Technical field
This utility model relates to a kind of transducer probe, refers in particular to a kind of transducer list probe that is used for the High Intensity Focused Ultrasound tumor-treating machine.
Background technology
The High Intensity Focused Ultrasound tumor-treating machine is the relatively more effective forward position of the treatment tumor equipment that is in developmental stage, wherein need launch ultrasound wave along different angles by a plurality of transducer lists probes, thereby constitute a ultrasound field.The operation principle of transducer as shown in Figure 1, it produces ultrasound wave by piezoquartz 2, its gross energy is divided into the P to the positive direction transmission
1With P to the opposite direction transmission
2, and P
1=P
2The structure of existing transducer list probe is bonded in piezoquartz 2 on metal-backed 9 through bond layer 8 as shown in Figure 2, wherein the ultrasonic energy P that transmits to positive direction
1Can be utilized, and remove some by bonding agent and metal-backed the absorption to the ultrasonic energy of transmission in the other direction, cause outside a large amount of unnecessary heat energy, some is by piezoquartz, bonding agent and metal-backed multiple reflection, refraction and scattering, this multiple reflection, refraction and scattering have not only caused the waste of energy, also upset forward and transmitted hyperacoustic field structure, brought hidden danger to medical effect.
Summary of the invention
The technical problems to be solved in the utility model is, providing a kind of can reflect the ultrasonic energy of reverse transfer regularly, make itself and positive direction transmit the ultrasonic energy addition, do not cause the heating of metal shell, do not upset the transducer list probe of ultrasound field structure simultaneously yet with the form of multiple reflection, refraction and scattering.
The technical scheme of taking for solving the problems of the technologies described above is: a kind of transducer list probe that is used for the ultrasonic tumor machine is made of piezoquartz 2, earth lead 5, holding wire 6, high-frequency high-power signal source 7 and shell 1, felt pad 3 and snap ring 4.Shell 1 is an annular, the one side round platform that extended internally, snap ring 4 is the dome shape, the centre of cover is a hollow, snap ring 4 is crimped on piezoquartz 2 on the round platform of shell 1 from the inside of shell 1, and felt pad 3 pads are connected between piezoquartz 2 and the snap ring 4, are formed with cavity between piezoquartz 2 and the snap ring 4, the outer surface of piezoquartz 2 welds together through earth lead 5 and shell 1, and the inner surface of piezoquartz 2 welds together through holding wire 6 and high-frequency high-power signal source 7.
Piezoquartz 2 is an arc.
The inside and outside surperficial evaporation of piezoquartz 2 has conductive silver slurry layer.
Compared with prior art the utility model has the advantages that:
1, improves the utilization ratio of transducer: owing between piezoquartz and snap ring, form a reflecting chamber, it can reflect the ultrasonic energy of reverse transfer regularly, the ultrasonic energy addition that itself and positive direction are transmitted reaches more than 90% the utilization ratio of transducer.
2, reduce the thermal losses of transducer: owing to avoided being produced a large amount of heat energy by bonding agent and metal-backed absorption, reduce the thermal losses of transducer, save the heat abstractor of transducer to the ultrasonic energy of transmission in the other direction.
3, reduced interference:, strengthened the curative effect of therapy apparatus to patient's focus because this structure has been avoided because of multiple reflection, reflected and be scattered in the interference that ultrasound field is constituted to ultrasound field.
