Device for ultrasonic stimulation of neural tissue

Abstract

The present invention relates to a device for the ultrasonic stimulation of a neural tissue. A control and data communication unit receives a control command to generate a pulse parameter and a beam-forming parameter. The ultrasonic echo radio frequency data outputted by an echo receiving unit is received and is transmitted to a control and ultrasonic imaging unit. A pulse excitation unit generates a high voltage pulse sequence according to the pulse parameter. The echo receiving unit composes ultrasonic echo radio frequency data according to the beam-forming parameter by using ultrasonic echo. The control and ultrasonic imaging unit emits a control command according to a user operation. The ultrasonic imaging of a target neural tissue scanning area is carried out according to the ultrasonic echo radio frequency data. An ultrasonic transducer array is controlled to be in a neural simulation state or an ultrasonic imaging state according to the high voltage pulse sequence. According to the technical scheme of the utility model, a method of sharing the ultrasonic transducer array by ultrasonic stimulation and ultrasonic imaging is employed, the real-time visualization of an ultrasonic neural stimulation process is realized, and the dynamic adjustment of stimulation target position and stimulation effect evaluation is helped.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for ultrasonic stimulation of nerve tissue. Background technique [0002] Nerve stimulation and regulation refers to the process of acting on the living nervous system (such as organisms, organs, tissues, cells, etc.) and causing responses by using physical stimuli such as electricity, light, sound, cold, heat, or machinery, as well as chemical stimuli. According to the effect of stimulation regulation, it can be divided into excitatory stimulation that makes function display or enhancement and inhibitory stimulation that makes function disappear or weaken. By stimulating and regulating neural activity, it is helpful to treat nervous system diseases and mental diseases, and it is also a basic means for studying human brain feelings, actions and cognitive functions. [0003] Electrical stimulation is the most widely used stimulation method. As early as 1870, the...
