Embodiment 1

[0029] This embodiment provides an ultrasonic device, such as figure 1 As shown, at least one miniature ultrasonic probe 1 is included, as well as an ultrasonic sending and receiving circuit 2 and a processor 3. The miniature ultrasonic probe 1, the ultrasonic sending and receiving circuit 2 and the processor 3 are connected in sequence, and an ultrasonic imaging module connected to the processor 3 is also included. 4. The miniature ultrasonic probe 1 includes at least one miniature single-element ultrasonic assembly 11 or miniature multi-element ultrasonic assembly 12 .

[0030] Preferably, the ultrasound device is implantable, that is, the micro-ultrasound probe 1 can be implanted in a living body; further, the micro-ultrasound probe 1 can be implanted into the brain to obtain accurate information of deep layers in the brain.

[0031] The research on the mechanism of neurovascular coupling in epileptic state verified the existence of neurovascular coupling in epileptic state...

Embodiment 2

[0042] This embodiment provides an ultrasonic device. The difference from the above-mentioned embodiment 1 is that in this embodiment, the miniature ultrasonic probe 1 includes more than one miniature multi-element ultrasonic assembly 12, and the miniature multi-array element ultrasonic assemblies 12 are arranged in parallel at least a row. Specific as Figure 4 As shown, 8 miniature multi-element ultrasonic assemblies 12 are arranged in two columns, each column has four. In addition, other numbers of miniature multi-element ultrasonic assemblies 12 can also be selected according to the needs of use to form miniature linear array ultrasonic probes in other arrangements. Specifically, the number of miniature multi-element ultrasonic components 12 can be 2, 4, 6 or 10, etc., and the number can be determined according to the approximate position of the lesion detected by using the existing non-invasive detection technology, or can be determined according to Other actual conditi...

Abstract

The invention provides an ultrasonic device and belongs to the technical field of medical devices. The ultrasonic device comprises at least one miniature ultrasonic probe, an ultrasonic receiving and transmitting circuit and a processor; the miniature ultrasonic probe, the ultrasonic receiving and transmitting circuit and the processor are connected in sequence. The ultrasonic device further comprises an ultrasonic imaging module connected with the processor; the miniature ultrasonic probe comprises at least one miniature single array element ultrasonic component or a miniature multi-array element ultrasonic component. According to the ultrasonic device provided by the invention, ultrasonic function imaging is finished by utilizing reflected ultrasound capable of reflecting deep brain activities acquired by the miniature ultrasonic probe on the surface of an intracranial brain in real time, so that according to an ultrasonic image acquired by a patient during the period of epileptic seizure, the epileptogenic focus can be accurately positioned or lesion areas of other cerebral diseases are accurately positioned; deep tissue information can also be accurately obtained by implanting the miniature ultrasonic probe into other tissues.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an ultrasonic device. Background technique [0002] Epilepsy is a common and frequently-occurring disease worldwide. There are more than 40 million people suffering from epilepsy in the world, and there are more than 10 million epilepsy patients in my country, of which 6 million patients still have seizures every year, and there will be 400,000 new cases every year. Drug control is the first choice for epilepsy treatment, but about 30% of epilepsy patients are resistant to antiepileptic drugs and can only choose surgery. The principle of epilepsy surgery is to remove the epileptogenic focus, that is, the dysfunctional area that generates or spreads epilepsy, and then alleviates or eliminates the seizures. However, surgical cure rates for patients with cryptogenic epilepsy of neocortical origin are only 10-30%. The reason for the low cure rate is the lack of a metho...
