Abstract
The invention provides a composite probe for cirrhosis detection, which comprises a shell, a shearing wave vibration generator, an ultrasonic transducer bracket, a shearing wave probe and an ultrasonic transducer, wherein the shearing wave probe is connected with the shearing wave vibration generator; and the ultrasonic transducer is fixed to the shell by the ultrasonic transducer bracket. Because the ultrasonic transducer and the shearing wave probe are not connected, the ultrasonic transducer is not shifted along with the vibration of the shearing wave probe, and the ultrasonic transducer and the shearing wave probe relatively independently work, the ultrasonic transducer is less influenced by the vibration of the shearing wave probe; and accordingly, the invention is beneficial to ensuring the precision and stability of detection, can prevent or simplify a compensating algorithm and solves the technical problems of easy influence on precision and stability and larger software calculation amount in the prior art.
Description
Technical field
The present invention relates to a kind of composite probe for cirrhosis detector, belong to medical instruments field.
Prior art
The liver cirrhosis detector is based on Ultrasonic Elasticity Imaging, by the hardness that detects liver or the process that elasticity is estimated hepatic fibrosis and liver cirrhosis.At present the existing patent No. is that 03819132.6 patent has been described the elastic device of a kind of measurement human or animal organ, be used in particular for the elastic measurement of liver, be primarily characterized in that, used an actuator, comprise that a servo-electric actuator is fixed on ultrasonic transducer.In this technology, ultrasonic transducer is followed actuator vibration, this structural design easily affects the emission of ultrasonic transducer signal and receives, easily stability and the accuracy of measuring impacted, and when carrying out the ultrasonic signal processing, need to the displacement of ultrasonic transducer generation of vibration be compensated, thereby increased the software operand.In addition, because actuator is connected with ultrasonic transducer, limited the quantity of available ultrasonic transducer, detected or two-dimensional imaging thereby be difficult to carry out multiple spot simultaneously.
Summary of the invention
The invention provides a kind of for composite probe for cirrhosis detector, to solve precision and stability susceptible in prior art, technical problem that the software operand is larger.
In order to solve above technical problem, the technical scheme that the present invention takes is:
A kind of composite probe for cirrhosis detector, comprise housing, shearing wave vibration machine, shearing wave probe and ultrasonic transducer, the shearing wave probe is connected with the shearing wave vibration machine, it is characterized in that, also comprise the ultrasonic transducer support, described ultrasonic transducer is arranged on described ultrasonic transducer support, and the ultrasonic transducer support is fixedly connected with housing.
Be provided with feet on described ultrasonic transducer support, be provided with opening on described shearing wave probe, the feet of described ultrasonic transducer support passes and is fixed on housing by the opening on described shearing wave probe.
Described ultrasonic transducer exceeds shearing wave probe certain distance, between described ultrasonic transducer and ultrasonic transducer support or between ultrasonic transducer support and housing, the resilient support thing is arranged.
Described ultrasonic transducer has a plurality of, and described a plurality of ultrasound transducer arrays are arranged.
Carriage and certain sliding space are arranged between described a plurality of ultrasonic transducer and ultrasonic transducer support.
Described ultrasonic transducer support and shearing wave probe can bend to certain radian for flexible material.
Described shearing wave vibration machine, shearing wave probe, ultrasonic transducer support, one or more ultrasonic transducer consist of an independently detecting unit, and described detecting unit has a plurality of, and described a plurality of array of detection units are arranged on the base of flexible material.
Carriage and certain sliding space are arranged between described a plurality of detecting unit and described base.
After having adopted technique scheme, owing to not being connected between ultrasonic transducer and shearing wave probe, ultrasonic transducer does not produce displacement with the vibration of shearing wave probe, ultrasonic transducer and shearing wave probe are worked relatively independently, therefore ultrasonic transducer is subjected to the impact of shearing wave probe vibration less, therefore be conducive to guarantee the precision that detects and stable, can avoid or simplify backoff algorithm, solved precision and stability susceptible in the prior art, technical problem that the software operand is larger.Be conducive to improve the speed of system works.Adopt in addition a plurality of ultrasonic transducers or a plurality of detecting unit, can realize easily that multiple spot detects and two-dimensional imaging simultaneously.The employing ultrasonic transducer exceeds the scheme of the also subsidiary resilient support thing of certain distance, can guarantee ultrasonic transducer and person under inspection's body surface close contact when detecting, and in guaranteeing to detect, ultrasonic signal emission and reception is unimpeded.Adopt ultrasonic transducer or detecting unit to contain the scheme of carriage, can adjust flexibly according to person under inspection's build difference position and the spacings of ultrasonic transducer.Adopt shearing wave probe and ultrasonic transducer support or the detecting unit base of flexible material, can crooked certain radian, to adapt to rib intermittently as the feature of arc.
