Technical Field
The utility model relates to a medical device, in particular to ultrasonic testing device.
Background
The radial artery-cephalic vein internal fistula is a preferred path for hemodialysis of a patient with renal failure, a cephalic vein is matched with a radial artery operation before the operation, the inner diameter of the cephalic vein and proper position selection are critical to the success rate of fistula formation, if the measurement of the inner diameter of the cephalic vein is inaccurate, the fistula formation operation fails, and if the position selection of the cephalic vein is too high, the cephalic vein resources of the later-stage re-fistula formation are wasted.
The traditional method for measuring the internal diameter of the head vein is to directly contact the skin to measure after the ultrasonic probe is smeared with the couplant, but the position of the head vein is shallow, so that the head vein is easily deformed by the pressure of the ultrasonic probe of an operation doctor, the measurement of the internal diameter of the head vein is inaccurate, and the measurement value is possibly smaller. The results of two measurements performed by the same doctor and two measurements performed by different doctors have large difference and poor operation repeatability, which affects the success rate of the later operation.
Moreover, the position of the cephalic vein is shallow, the distance between the cephalic vein and the ultrasonic probe is short, and the cephalic vein is positioned in the near field of ultrasonic waves, so that the image quality is poor, and the measurement is inaccurate. The wrist is uneven because of the human body shape, the ultrasonic probe can not be in good contact with the wrist skin, and the tissue range which can be displayed by ultrasonic is limited.
In addition, ultrasound testing is also used to detect median nerve stiffness. The hardness of the median nerve can be changed due to diseases such as carpal tunnel syndrome and peripheral neuropathy caused by diabetes, so that the measurement of the hardness of the median nerve is particularly important for diagnosing and evaluating the diseases. Shear wave elastography is a new technology for measuring median nerve hardness, but in the measuring process, the requirements on an operator are high, the probe of the operator is required to be stable, and the pressure action on the skin cannot be generated, because if the probe generates the pressure action on the median nerve, the median nerve pre-hardness is increased, so that the measured value has errors and inaccuracy. The median nerve is positioned on the superficial surface of the skin, is very close to the skin and is easily stressed by the pressure of the probe, and the pressure used by different operators is different, so the pre-hardness of the median nerve is different, and the final measured value is inaccurate and unstable. Meanwhile, in the measuring process, an operator needs to keep the ultrasonic probe stable, does not press the skin as much as possible, keeps long-time observation, and is easy to fatigue arms.
