Embodiment Construction

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

[0014] Such as 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 len...

Abstract

The invention provides an implantable neural signal blocking device which comprises a flexible curling substrate, a first Kraft electrode, a second Kraft electrode and a signal processing module. The first Kraft electrode, the second Kraft electrode and the signal processing module are arranged on the surface of the flexible curling substrate, the first Kraft electrode is disposed at a nerve bundle source end or near end transmitting signals, and the second Kraft electrode is disposed at a far end of a nerve bundle. The first Kraft electrode is adopted to detect motor nerve impulse signals causing muscle spasm or sensory nerve action potential signals causing pain, the motor nerve impulse signals or the sensory nerve action potential signals are amplified, amplified signals are delayed and reversed necessarily according to transmission speed of action potential in neurons to enable the amplified signals to appear on the second Kraft electrode before the action potential reaches an interception site, offset of the action potential signals in a nerve segment on which blocking is applied is realized, and the objective of eliminating muscle spasm or pain is achieved.

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...
