Embodiment Construction

[0013] The present invention will be further explained below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, an implantable nerve signal blocking device includes a flexible curled substrate 4 , and a first Kraft electrode 1 , a second Kraft electrode 2 , and a signal processing module 3 arranged on the surface of the flexible curled substrate 4 . When in use, the flexible curled substrate 4 will curl itself to form a cylinder and wrap the nerve bundle. The shapes of the first Kraft electrode 1 and the second Kraft electrode 2 are two parallel metal strips. The first Kraft electrode 1 and the second Kraft electrode 2 are arranged in parallel along the curling direction of the flexible curled substrate 4. The kraft electrode 1 is arranged at one end of the length direction of the flexible curled substrate 4 and connected to the input end of the signal processing module 3, and the second kraft electrode 2 is arranged at the other end of the length...

Abstract

An implantable nerve signal blocking device proposed by the present invention includes a flexible curled substrate, a first kraft electrode, a second kraft electrode, and a signal processing module arranged on the surface of the flexible curled substrate. The first Kraft electrode is placed at the source or proximal end of the nerve bundle that sends out the signal, and the second Kraft electrode is placed at the distal end of the nerve bundle. Use the first Kraft electrode to detect the motor nerve impulse signal that causes muscle spasm or the sensory nerve action potential signal that causes pain, amplify it, and perform necessary adjustments on the amplified signal according to the propagation speed of the action potential in the neuron Delay and reverse, so that it can appear on the second Kraft electrode before the action potential reaches the "intercept" site, so as to realize the cancellation of the action potential signal in the nerve segment where the block is applied, so as to eliminate muscle spasm or pain sense of purpose.

Description

technical field [0001] The invention belongs to the cross field of rehabilitation medicine and electronic science, and relates to an implanted nerve signal blocking device. Background technique [0002] Nerve signal blockade is of great significance to the clinical research and treatment of many diseases, and it is a research hotspot in the medical field at present. This technology has a wide range of uses, such as inhibiting muscle spasms on the affected side of hemiplegic patients; eliminating pain; selectively stimulating the bladder sphincter and detrusor muscles to rebuild and improve the voiding function of patients with spinal cord injuries; selectively stimulating the vagus nerve to regulate heart rate, etc. Wait. At present, pressure, local low temperature, drugs and other means are often used to suppress muscle spasm and pain, but the process of starting and stopping the blocking is slow. Contents of the invention [0003] Purpose of the invention: Aiming at th...
