Ultrasound area array probe for deep brain stimulation and neuromodulation and preparation method thereof

Abstract

The invention relates to an ultrasound area array probe for deep brain stimulation and nerve regulation and control and a preparation method of the ultrasound area array probe. According to the method, M*N type piezoelectric composite materials are firstly prepared; electrode cutting division is performed after the electrode layer sputtering; by using a cutting process, electrode signal lead wires in opposite sides are led to the same side; then, a first matching layer, a second matching layer and a sound lens are added; finally, a hollow FPC (Flexible Printed Circuit) board is welded on a row electrode or a column electrode of an area array; next, a back lining layer is added; and a prepared probe is encapsulated by a case. A piezoelectric composite material array single-side row and line wiring mode is used; the work state of each array element is selected and controlled by the on-off state of voltage in a certain row (or line) and a certain line (or row); and the number of the lead wires is reduced. Meanwhile, the single-side concentrated wire leading mode is used, so that simplicity, high speed and reliability are realized. Therefore no limitation exists on whether the matching layers and the back lining layer conduct electricity or not; the matching layers and the back lining layer do not need to be cut; and the process difficulty and the complexity are reduced.

Description

technical field [0001] The invention relates to an ultrasonic radiation force probe, in particular to an ultrasonic surface array probe with a simple process for deep brain stimulation and neural regulation and a preparation method thereof. Background technique [0002] Ultrasound probes are key components in ultrasound equipment. For example, through the imaging of ultrasonic diagnostic equipment, ultrasonic diagnostic equipment transmits ultrasonic signals and processes echo signals reflected by tissues, and obtains images of the nature and structure of tissues through system post-processing. As we all know, this device is harmless to the human body and can obtain three-dimensional tomographic imaging, compared with X-ray diagnostic equipment, magnetic resonance imaging, and nuclear medicine diagnostic equipment. Moreover, ultrasound imaging also has the advantages of real-time imaging, small size, and low price. The two-dimensional area array ultrasound probe adopts the ...

Problems solved by technology

Each array element of a traditional two-dimensional area array ultrasonic probe is individually controlled by wires, so the M*N (M, N can be arbitrary values) two-dimensional area array ultrasonic probe array requires M*N lead wires. It is very complicated and inconvenient to operate
