[0002] In the current field of medical ultrasound, single-element ultrasound small probe technology plays an important role in the screening of early cancer and submucosal lesions. This technology mainly relies on B-mode imaging, which can penetrate the tissue structure under the surface of the cover point and provide detailed information about the changes in the tissue for the doctor. However, the existing single-element ultrasound small probe has some limitations in use.

[0003] Specifically, due to the high-speed rotation of the transducer, as well as the vibration of the catheter itself and the transmission of the ultrasound wave through the curved surface of the outer catheter, the position of the transducer will change significantly, which will cause a large energy loss. This not only affects the quality of imaging, but also can cause image distortion or resolution degradation. In addition, when trying to add Doppler mode on the basis of single-element ultrasound probe to obtain more comprehensive diagnostic information, it will be found that this will have a significant impact on the frame rate of imaging and Doppler, thus greatly reducing the practicability of the Doppler mode.

[0029] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be described clearly and completely below by combining with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0030] It should be noted that the endoscopic ultrasonic small probe is a kind of instrument that enters human body through endoscopic forceps channel to carry out ultrasonic examination on various natural cavities inside human body. It adopts higher ultrasonic frequency to carry out diagnosis, and compared with external ultrasonic, its imaging resolution and delicate degree have obvious improvement. It is mainly divided into single array rotating probe and multi-array probe. Single array rotating probe realizes circumferential scanning through mechanical rotating component, obtains ultrasonic image of the whole section, so as to understand diagnostic information such as lesion nature, stenosis degree, source level or infiltration depth of the disease cavity tissue. At present, the probe is mainly applied to early cancer screening, diagnosis in the fields such as submucosal lesion and stenosis lesion in digestive system, respiratory system, urinary system and biliary and pancreatic duct system.

[0031] Doppler ultrasound is to use the principle of acoustic Doppler, the reflected echo of moving organs and blood (mainly red blood cells) Doppler frequency shift signal detection processing, conversion into sound, waveform, color and brightness signals. This is mainly divided into continuous wave Doppler (continuous wave Doppler-CW), pulsed wave Doppler (pulsed wave Doppler-PW) and color Doppler flow imaging (color Doppler flow image-CDFI). Among them, continuous wave Doppler and pulsed wave Doppler belong to one-dimensional Doppler technology (also known as spectral Doppler or sound Doppler), can only reflect one-dimensional beam on the Doppler blood flow information. These two are very convenient and effective for the need to determine the blood flow information at a certain position, can measure the blood vessel position, blood flow direction and speed information. Continuous wave Doppler uses two transducers, one for transmitting ultrasonic waves, the other for receiving reflected echoes, all blood flow signals in the scanning range will be recorded, but the feature is no distance resolution for high-speed blood flow measurement. Pulsed wave Doppler uses the same transducer to transmit and receive ultrasonic waves intermittently, which can accurately display the position, depth and flow rate of blood flow information, but is mainly suitable for low-speed blood flow measurement. Continuous and pulsed Doppler transducers and system development design is relatively easy, cost is more economical and practical, at present in the fetal heart monitoring and transcranial blood flow and other abnormal diagnosis has been widely used. CDFI has strong blood flow display capability, according to the moving direction, speed and dispersion of red blood cells, adjusts the red, green and blue three primary colors, and changes its brightness, superimposed on the B-ultrasound two-dimensional section tissue image, displays the blood flow distribution, blood flow direction, blood flow velocity and blood flow type is laminar flow, vortex or turbulent flow and other characteristics. In CDFI, the speed is represented by different color tones, the higher the flow rate, the higher the color tone and the brighter the color; on the contrary, the lower the flow rate, the lower the color tone and the darker the color. The direction of the speed is represented by red and blue colors, the blood flow towards the probe, i.e. positive frequency shift, is marked as red, and the blood flow away from the probe, i.e. negative frequency shift, is marked as blue. Therefore, CDFI can more directly reflect the relationship between structural abnormalities and hemodynamic abnormalities, but its overall system technology threshold is higher, the development cycle is long and the cost is expensive.
