Ultrasonic probe for endoscope

Abstract

The invention relates to an ultrasonic probe for an endoscope. A rotating mechanism and a movement mechanism are arranged in a drive unit to drive a hollow flexible shaft to move and rotate, so that a minitype ultrasonic probe installed at the end of the hollow flexible shaft can move and rotate. The drive unit is arranged far from the minitype ultrasonic probe to avoid the image dithering, so that the image is clearer; and the ultrasonic probe can implement multiple annular section surface scanning, and can form a stereoscopic image at the imaging part of an ultrasonic scanning system of theendoscope or form a annular section image and a longitudinal section image passing through the axial line at the imaging part of the ultrasonic scanning system of the endoscope, thereby expressing the pathological change tissue conditions in a more visual, clearer and more accurate way, so that the image can be diagnosed in an easier and more accurate way.

Description

technical field [0001] The invention relates to an ultrasonic diagnostic device, in particular to an endoscopic ultrasonic probe. Background technique [0002] In the diagnosis of body cavity lesions, the method of inferring the lesions simply based on the morphological changes of the tissue surface has certain subjectivity and limitations. The endoscopic ultrasound imaging system can perform ultrasonic scanning through the transducer in the micro-ultrasound probe to obtain relatively clear and accurate tomographic images of tissues and organs, which provides an objective basis for doctors to treat symptoms. [0003] At the same time, the endoscopic ultrasound scanning system inserts its micro-ultrasound probe through the reserved channel of the endoscope (such as the forceps channel) such as the digestive tract, and inserts it into the body cavity organ, so that the lesion shape of the mucosal surface can be directly observed through the endoscope, and the Ultrasound scann...

AI Technical Summary

Problems solved by technology

Because the driving device is too close to the ultrasonic transducer, the ultrasonic transducer is affected by the driving device and vibrates, resulting in shaking and blurring of the obtained image

In addition, the above-mentioned micro-ultrasound probe can only obtain a circular slice scan image at a certain longitudinal depth, and it is difficult to make a diagnosis by relying on this circular slice scan image, and it is impossible to conduct a comprehensive exploration of the diseased tissue, and the diagnosis result is not accurate enough.
