Ultrasonic device

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...

Problems solved by technology

ECoG can only locate the epileptogenic focus originating from the gyrus, but cannot locate the epileptogenic focus located in the brain sulci, which affects the success rate of the operation
