Abstract
The utility model provides a composite probe used for detecting liver cirrhosis, which comprises a shell body, a shear wave vibration generator, an ultrasonic energy converter bracket, a shear wave probe and an ultrasonic energy converter. The shear wave probe is connected with the shear wave vibration generator, and the ultrasonic energy converter is fixed at the shell body by the ultrasonic energy converter bracket. As the ultrasonic energy converter is not connected with the shear wave probe, the ultrasonic energy converter doe not generate displacement along with the vibration of the shear wave probe, and the ultrasonic energy converter and the shear wave probe can work independently; therefore, the ultrasonic energy converter is affected a little by the vibration of the shear wave probe, so as to be beneficial for ensuring the detecting precision as well as stability and to avoid or simplify the compensating algorithm, thereby solving the technical problems in the prior art that the precision and stability can be easily affected and the software computing quantity is large.
Description
Technical field
This utility model relates to a kind of liver cirrhosis detector combined probe, belongs to medical instruments field.
Prior art
The liver cirrhosis detector is estimated the hardened process of hepatic fibrosis regulating liver-QI based on the ultrasonic elastograph imaging technology by the hardness or the elasticity that detect liver.The at present 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 the ultrasonic transducer.Ultrasonic transducer is followed actuator vibration in this technology, this structural design influences the emission of ultrasonic transducer signal easily and receives, easily measuring stability and accuracy are impacted, and when carrying out the ultrasonic signal processing, need the displacement that the ultrasonic transducer vibration produces be compensated, thereby increased the software operand.In addition,, limited the quantity of available ultrasonic transducer, detected or two-dimensional imaging thereby be difficult to carry out multiple spot simultaneously because actuator links to each other with ultrasonic transducer.
The utility model content
This utility model provides a kind of liver cirrhosis detector combined probe that is used for, to solve precision and stable susceptible in the prior art, technical problem that the software operand is bigger.
In order to solve above technical problem, the technical scheme that this utility model is taked is:
A kind of liver cirrhosis detector combined probe, 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 the described ultrasonic transducer support, and the ultrasonic transducer support is fixedlyed connected with housing.
Described ultrasonic transducer support is provided with feet, and described shearing wave probe is provided with opening, and the feet of described ultrasonic transducer support passes by the opening on the described shearing wave probe and is fixed on the housing.
Described ultrasonic transducer exceeds shearing wave probe certain distance, between described ultrasonic transducer and the ultrasonic transducer support or between ultrasonic transducer support and the housing 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 constitute 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 the described base.
After having adopted technique scheme, because ultrasonic transducer and shearing wave are not connected between popping one's head in, 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 influence of shearing wave probe vibration less, therefore help guaranteeing the precision that detects and stable, can avoid or simplify backoff algorithm, solved precision and stable susceptible in the prior art, technical problem that the software operand is bigger.Help improving the speed of system works.Adopt a plurality of ultrasonic transducers or a plurality of detecting unit in addition, 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 that ultrasonic transducer closely contacts with person under inspection's body surface when detecting, and ultrasonic signal emission and reception is unimpeded in guaranteeing to detect.Employing ultrasonic transducer or detecting unit contain the scheme of carriage, can be according to different position and the spacings that adjust ultrasonic transducer flexibly of person under inspection's build.Adopt shearing wave probe and the ultrasonic transducer support or the detecting unit base of flexible material, can crooked certain radian, intermittently be arcual feature to adapt to rib.
