Problems solved by technology

[0002] Ultrasound elastography is widely used clinically by obtaining information about tissue elasticity, and has become a research hotspot in elastography in January. The basic principle of elastography is to apply an internal or external dynamic or static excitation to the tissue. Under the action of physical laws such as mechanics and biomechanics, the tissue will produce a response, such as a certain change in the distribution of displacement, strain, and velocity. Using ultrasonic imaging methods, combined with digital signal processing or digital image processing technology, the internal tissue can be estimated. Correspondingly, in the elastography process, it is necessary to move the probe to detect the human body. After moving to a part each time, it needs to be pressed down several times to obtain a relatively stable elastography image. During the detection process, it is always kept The contact between the probe and the body surface prevents air from entering and affecting the elastography. Now most of the operations of elastography are done manually, which requires a high level of applicators and is labor-intensive. Moreover, manual work is more affected by human factors, and mistakes are prone to make the elasticity Imaging is not clear, so it is necessary to design a device to replace manual elastography

Embodiment Construction

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0016]The hydraulic ultrasonic probe used for elastography, as shown in the figure, includes a mounting base 1. The top left end of the mounting base 1 is equipped with a vertical column 2 through a rotating device. The rotating device can control the rotation angle of the column 2 and can align it For locking, the upper right side of the column 2...

Abstract

The invention provides a hydraulic ultrasonic probe for elasticity imaging. The hydraulic ultrasonic probe for elasticity imaging comprises an installing seat, wherein the installing seat is providedwith a vertical upright post through a rotating device; a first cylinder body is arranged on the upright post; the right end of the first cylinder body is provided with an opening; a first piston block is arranged in the first cylinder body in a cooperative way; a first rod body is fixedly arranged at the right side wall of the first piston block; vertical elastic telescopic rods are symmetricallyarranged at the upper and lower side walls of the first rod body; and a hemispheroid is arranged on each of the elastic telescopic rods. The ultrasonic probe is controlled to press the human body formany times through a reciprocating ascending and descending device; meanwhile, the reciprocating ascending and descending device does vertical reciprocating movement for a certain number of times, and then, the ultrasonic probe can be pushed to move a certain distance to detect the next region of the human body; in addition, in the moving process, the ultrasonic probe is enabled to be always in contact with the body surface of a patient; and in addition, through the cooperation of the elastic telescopic rod, the hemispheroids and arc-shaped grooves, the counting effect is achieved on the number of the vertical reciprocating movement times of the ultrasonic probe, so that the downwards pressing number of the ultrasonic probe in each time is identical, and the influence of the elasticity imaging result on the judgment of doctors is avoided.
