Miniature intrusive medical ultrasonic imaging front-end device based on acoustic prism

Abstract

The invention discloses a miniature intrusive medical ultrasonic imaging front-end device based on an acoustic prism. The miniature intrusive medical ultrasonic imaging front-end device comprises a probe and a control handle; the probe and the control handle are connected through a flexible pipe; the probe comprises a columnar shell, one end of the shell is open and installed on the flexible pipe, and the other end of the shell is closed; an ultrasonic imaging mechanism A and an ultrasonic imaging mechanism B are sequentially arranged in the shell; the ultrasonic imaging mechanism A is arranged at the closed end in the shell and used for transverse probing; the probing plane of the ultrasonic imaging mechanism B points to the side face of the shell and the ultrasonic imaging mechanism B is used for longitudinal probing; the ultrasonic imaging mechanism B is connected with an adjusting mechanism; and the adjustment mechanism is used for adjusting rotation of the ultrasonic imaging mechanism B around the axis of the shell. The device can conduct transverse probing and longitudinal probing on focus tissue, can conduct longitudinal probing on the focus tissue at different angles under the condition that it is guaranteed that the shell is not moved, and avoids the situation that in traditional probing, when probing is conducted at different angles, rotating of the probe brings pain to a patient.

Description

technical field [0001] The invention relates to the field of medical ultrasound imaging, in particular to a miniature interventional medical ultrasound imaging front-end device based on an acoustic prism. Background technique [0002] B-mode ultrasound is the main examination method of ultrasound, and the development of ultrasound is advancing by leaps and bounds, such as endoscopic ultrasound, contrast-enhanced ultrasound, three-dimensional imaging, elastography, etc., are all developed on the basis of B-mode ultrasound. [0003] Ultrasound imaging principle: Ultrasound examination is an examination method that uses the physical characteristics of ultrasound and the differences in the acoustic properties of human organs and tissues to display and record in the form of waveforms, curves or images for disease diagnosis. Various organs and tissues of the human body have their specific acoustic impedance and attenuation characteristics, thus forming differences in acoustic impe...

Problems solved by technology

[0005] The existing double-plane intracavity probe can be a combination of convex array and linear array, or a combination of convex array and convex array. This combination of two arrays can expand the scanning range, and can Observing the lesion from two cut planes is beneficial to the examination and location of the lesion. Through the research on the existing technology, although the existing dual-plane ultrasonic diagnostic probe can perform two-plane imaging in the cavity at the same time, due to the two The scanning planes are separated from each other, and there is no continuity in time and space, the status of the lesion cannot be visually evaluated, and the accuracy of locating the lesion is poor

In addition, the existing convex-convex intersecting dual-plane probe directly contacts the intracavity tissue during scanning, so there will be near-field blind spots and side lobe artifacts, and in order to fully detect the lesion tissue, it is necessary to rotate the probe to detect lesion tissue at different positions When turning the probe, the probe will touch and move the tissue in the cavity, which will bring pain to the patient and cannot meet the current use requirements
