Device for generating sine-wave excitation movement and detection system applying same

Abstract

The invention relates to a device for generating sine-wave excitation movement, which comprises a vibration unit. The vibration unit comprises a sine-wave vibration module for generating sine-wave excitation movement and a lock-up module for controlling the sine-wave vibration module to generate sine-wave excitation movement of single cycles, wherein the lock-up module locks the sine-wave vibration module to control the sine-wave vibration module to generate sine-wave excitation movement of single cycles when the lock-up module generates one cycle of sine-wave excitation movement on the sine-wave vibration module. By constructing the device capable of generating the sine-wave excitation movement, the lock-up module controls the sine-wave vibration module to generate sine-wave excitation movement of single cycles, thereby preventing subsequent mechanical vibration from generating interference on mechanical vibration of the former cycle in use and improving the service effect of the device.

Description

technical field [0001] The invention relates to a device and an application system for generating a sine wave excitation motion, in particular to a device and an application system for generating a single cycle sine wave excitation motion. Background technique [0002] Vibration devices are an important component in devices that measure the elasticity of human or animal organs. This device is usually used to measure the elasticity of human or animal organs (such as the liver). When used, it needs to generate mechanical vibrations of a certain frequency outside the organ to be measured (such as the liver), and then emit ultrasonic waves to the organ. The ultrasound returned by the organ judges the elasticity of the organ, thereby judging the hardness of the organ. For example, the degree of fibrosis in the liver. In the prior art, the commonly used vibrating components generate a series of mechanical vibrations on the outside of human or animal organs. This mechanical vibra...

Problems solved by technology

[0003] The technical problem solved by the present invention is to construct a device that generates a single-period sine wave excitation motion, which overcomes the fact that mechanical vibration in the prior art usually includes multiple vibration periods, and the mechanical vibration of the subsequent period will interfere with the previous mechanical vibration and thus affect Technical Issues in Measuring Effects of Elasticity
