Method for manufacturing flexible spiral electrode and nerve tract detection and treatment device

Abstract

The disclosure relates to a method of manufacturing a flexible spiral electrode and a nerve tract detection and treatment device. The method comprises: a substrate is heated to be at a transformationtemperature and the substrate winds around a first forming rod spirally to form a to-be-formed substrate; the temperature of the to-be-formed substrate is kept to be larger than or equal to a first plastic deformation within first time and thus a spiral substrate is formed; the spiral substrate is heated to be at a transformation temperature and the substrate is flattened to obtain a flattened substrate; a metal electrode is transferred to the flattened substrate; a lead is connected to a lead connection end of the metal electrode, so that an electrical stimulation signal is sent to the metalelectrode through the lead and/or an electrical signal of a nerve tract in contact with the metal electrode is obtained; heating is carried out to reach a transformation temperature and thus the shapeof the flattened substrate is transformed into a spiral shape, so that a flexible spiral electrode is obtained. The manufactured flexible spiral electrode has high extensibility and the contact degree and the matching degree with the nerve tract are high; and the operation is carried out conveniently. Moreover, the service life is long; the stability is high; and the side effects are low.

Description

technical field [0001] The present disclosure relates to the technical field of medical devices, and in particular, to a manufacturing method of a flexible spiral electrode and a nerve bundle detection and treatment device. Background technique [0002] As an important branch of neural regulation, peripheral nerve bundle stimulation plays an important role in the treatment of some drug-resistant diseases such as epilepsy, hypertension, and heart failure. In addition, the monitoring and stimulation of electrical signals in peripheral nerve bundles are also crucial in the recent development of neuroprostheses for the treatment of paralyzed patients. The nerve electrodes used for peripheral nerve bundle electrical stimulation and electrical signal acquisition mainly include Cuff electrodes and spiral structure electrodes. Among them, the spiral structure electrode has been proved to reduce the entrapment or frictional damage to the nerve, so it has gradually become the first c...

AI Technical Summary

Problems solved by technology

[0003] However, in related technologies, the metal electrodes in the spiral structure electrode are easy to debond, which is easy to cause mechanical damage to nerves and surrounding tissues.

At the same time, the metal electrode after debonding produces leakage current, which stimulates non-target tissues and causes great side effects, such as nausea, vomiting, headache, etc.

Moreover, the matching between the spiral structure electrode and the nerve bundle is poor. During the nerve deformation process, the spiral structure electrode still has a large binding and compression effect on the nerve, causing unnecessary side effects and inconvenient for doctors to operate.
