可多次使用的多通道电极装置Reusable multi-channel electrode assembly

【技术领域】【Technical field】

本发明涉及医疗器械领域，具体涉及一种可多次使用的多通道电极装置。The invention relates to the field of medical equipment, in particular to a multi-channel electrode device that can be used multiple times.

【背景技术】【Background technique】

20世纪40年代，随着技术和各种测量仪器的发展，科研人员能够从活体神经元中记录细胞内的电信号。通过用纤细的金属丝微电极和具有“箝位”配置的高增益的放大器，柯蒂斯和科尔记录了鱿鱼轴突内的电信号。该实验方法和数学模型为霍奇森和贺胥黎成功阐释离子膜电流在运动电位产生中的作用奠定了基础。他们的工作使神经元膜兴奋模型取代了早期伯恩斯坦的不同的钾离子膜渗透性模型，并为人们接受。霍奇森和贺胥黎由此获得了1963年的诺贝尔奖。更具意义的是，他们的模型预测了门控膜离子通道的存在。In the 1940s, with the development of technology and various measuring instruments, researchers were able to record intracellular electrical signals from living neurons. Using thin wire microelectrodes and high-gain amplifiers in a "clamp" configuration, Curtis and Cole recorded electrical signals inside squid axons. The experimental method and mathematical model laid the foundation for Hodgson and Huxley to successfully explain the role of ionic membrane current in the generation of motion potential. Their work made the neuronal membrane excitation model replace the earlier Bernstein's different potassium ion membrane permeability model, and it was accepted by people. Hodgson and Huxley won the Nobel Prize in 1963. More significantly, their model predicted the existence of gated membrane ion channels.

目前，神经元网络的研究引起了人们极大的兴趣；为了更好地理解中枢神经系统神经元之间复杂的相互关系，和为开发实用的神经假体提供所需的高度保真的知觉和控制信息，这就需要具备一种有选择且具有良好空间分辨率，能记录和控制神经组织行为的能力。这对正确理解脑组织和感官知觉的过程十分重要。而这方面的发展，与微电极技术的发展息息相关。它要求微电极能够传输高质量和稳定的刺激信号，同时又能够长时间记录大量的神经束的电信息。通过对神经系统的理解，更好地治疗与中枢神经系统有关的疾病变得更为切实可行。更好地理解神经图谱和对感知过程的理解，为感觉或运动受损的患者设计假体装置，使其恢复正常的功能，变的更加容易。Currently, the study of neuronal networks is of great interest; to better understand the complex interrelationships between neurons in the central nervous system, and to provide the high-fidelity perception and Controlling information requires the ability to selectively record and control the behavior of neural tissue with good spatial resolution. This is important for a proper understanding of brain organization and the processes of sensory perception. The development in this area is closely related to the development of microelectrode technology. It requires that microelectrodes can transmit high-quality and stable stimulation signals, and at the same time be able to record a large number of electrical information of nerve bundles for a long time. Better treatment of diseases related to the central nervous system becomes more feasible through an understanding of the nervous system. With a better understanding of the neural map and understanding of perceptual processes, it becomes easier to design prosthetic devices for patients with sensory or motor impairments to restore normal function.

现有技术中，神经电信号采集电极最常用的是犹他电极和密歇根电极，前者适合大脑浅层区域的研究，后者适宜较深核团不同层神经元放电的信号采集。但是这两种电极均价格昂贵，且不可重复使用。此外，这两种电极并不能满足所有的实验要求。为了降低实验成本和最大限度地满足实验要求，现有技术中使用较多的另一类电极是金属丝电极。金属丝电极的优点是通道数和记录位点可以根据需要进行选择，适用范围广。该类电极虽然成本较低，但是制备过程非常耗费人力和时间，且不能多次使用。In the prior art, the most commonly used electrodes for collecting neuroelectric signals are Utah electrodes and Michigan electrodes. The former is suitable for the study of superficial areas of the brain, and the latter is suitable for signal collection of neuron discharges in different layers of the deeper nuclei. But both electrodes are expensive and not reusable. Furthermore, these two electrodes do not meet all experimental requirements. In order to reduce the cost of the experiment and meet the requirements of the experiment to the greatest extent, another type of electrode that is widely used in the prior art is the wire electrode. The advantage of wire electrodes is that the number of channels and recording sites can be selected according to needs, and the application range is wide. Although the cost of this type of electrode is low, the preparation process is very labor-intensive and time-consuming, and cannot be used multiple times.
