Problems solved by technology

However, since the piezoelectric element is not cut through, it is still connected together, and there will be a lot of crosstalk interference between the piezoelectric array elements.
And the layer-by-layer welding method is very cumbersome to calibrate each time, and it is not easy to calibrate to the precise position

Embodiment Construction

[0036] Such as figure 1 As shown, it is a flow chart of the preparation method of the large-scale area array ultrasound probe for deep brain stimulation and neuromodulation.

[0037] A method for preparing a probe of large-scale area array ultrasound for deep brain stimulation and neural regulation; comprising the following steps:

[0038] Before the step of getting the finely ground piezoelectric composite material, include:

[0039] The piezoelectric composite material 101 is finely ground until its thickness reaches a preset size.

[0040] Step S110, take the finely ground piezoelectric composite material, cut M rows of concave grooves along its transverse direction, and add decoupling material in the concave grooves; then cut N rows of concave grooves along its longitudinal direction, and The decoupling material is added in the shaped grooves; wherein, the direction of the M rows of concave grooves and the N columns of concave grooves is the same.

[0041] Specifically,...

Abstract

A deep brain-stimulated and nerve-regulated large-scale area array ultrasonic probe and a preparation method for the same are provided. First, MxN piezoelectric composite material is prepared; the piezoelectric composite material is cut through, so string sound interference between adjacent piezoelectric array elements can be greatly reduced. A technology method of sputtering electrode layer and electrode disperse cutting is employed. A first front electrode is dispersed according to array element arrangements; a ground electrode is not dispersely cut and led to a first front electrode layer via a binding electrode layer to reduce a ground electrode signal lead wire; meanwhile, single face concentrative wiring can be achieved; and the technology is simple and reliable. A multi-layered flexible circuit board is employed for wiring; an array of a lead wire end of the multi-layered flexible circuit board is the same as the array element arrangements; a two-side aligning method is employed to align the lead wire end of the multi-layered flexible circuit board and a lead wire end of the corresponding array element electrode signal; and an accurate position of the multi-layered flexible circuit board can be found and the electrode signal lead wire can be accurately lead out.

Description

technical field [0001] The invention relates to an ultrasonic radiation force probe, in particular to a large-scale area array ultrasonic probe with a simple process for deep brain stimulation and neural regulation and a preparation method thereof. Background technique [0002] Large-scale area array ultrasound probe for ultrasound deep brain regulation. Moreover, it is especially suitable for multi-point regulation for different brain neural function zones. In recent years, due to the global focus on research on the prevention and treatment of neurodevelopmental diseases and mental diseases, the Brain Science Program has officially started, and the majority of scientific and technological workers are looking for various means and methods to perform deep brain intervention and stimulation regulation on patients. The scale area array ultrasound probe is very convenient to adjust the size, intensity and direction of the focal point, so it can become a non-invasive tool and me...
