Ultrasonic neural control device with automatic take-up function

Abstract

The invention provides an ultrasonic neural control device with an automatic take-up function. The device includes an ultrasonic signal emitting module used for emitting a low-energy pulse voltage signal, an automatic take-up module used for transmitting the pulse voltage signal emitted by the ultrasonic signal emitting module to a transducer module through a cable and automatically stretching andcontracting the cable in the process of ultrasonic stimulation, and the transducer module used for receiving the pulse voltage signal, converting the pulse voltage signal into an acoustic pressure signal and emitting a low-frequency pulse ultrasonic signal needed by experiment. Through the automatic take-up module, a conscious animal can freely move in a behavioral tester without being wound by along cable or limited in movement area, so that the real-time behavioral and electrophysiological effects of ultrasound on animal stimulation can be explored, and the neural control effect of ultrasound can be evaluated in real time without anesthetizing an animal.

Description

technical field [0001] The invention relates to the field of ultrasonic nerve regulation, in particular to an ultrasonic nerve regulation device for automatic wire take-up. Background technique [0002] With the increasing number of patients with functional brain diseases such as Parkinson's, depression, and Alzheimer's disease, their effective treatment methods have gradually become the focus of modern medical research. Circuit of nerve conduction pathways. Compared with the electrical stimulation and magnetic stimulation of the existing control technology, ultrasonic stimulation has attracted increasing attention due to its safety and non-invasiveness. Many laboratories at home and abroad are conducting research on ultrasonic animal stimulation of the nervous system. [0003] In the existing ultrasonic neuromodulation device, since there is a long cable between the ultrasonic signal transmitting module and the transducer module, its length cannot be adjusted. During the u...

Problems solved by technology

[0003] In the existing ultrasonic neuromodulation device, since there is a long cable between the ultrasonic signal transmitting module and the transducer module, its length cannot be adjusted. During the ultrasonic stimulation of conscious animals, the animal is easily entangled by the long cable when moving, which limits The free movement of animals is affected, which in turn affects the effect of ultrasound stimulation, which is not conducive to evaluating the therapeutic effect of ultrasound on brain functional diseases
