Implantable flexible bioelectrode and manufacturing method thereof

Abstract

An implanted flexible biological electrode comprises an electrode simulation contact blade, a metal ring and a metal micro guide wire. The electrode simulation contact blade is communicated with the metal ring through the metal micro guide wire. Insulation layers formed by insulation materials in an injection molding mode are arranged outside the electrode simulation contact blade, the metal ring and the metal micro guide wire, and the surface of the electrode simulation contact blade and the surface of the metal ring are exposed out of the insulation layers. According to a manufacturing method of the implanted flexible biological electrode, the two ends of the helical metal micro guide wire are connected with the electrode simulation contact blade and the metal ring of a connecting end in sequence in a welding mode, the packaging is carried out, finally, finishing is carried out, a packaging sprue gate is removed, and the metal of the electrode simulation contact blade and metal of the metal ring of the connecting end are exposed out. The implanted flexible biological electrode is simple in process and easy to manufacture, the implanted flexible biological electrode is implanted close to the Phil neurons of the human leg, the metal ring is connected with an external circuit, electric signals are provided for the electrode simulation contact blade, and pulse electrical signal simulation is provided for the nerve at the position of the target spot of the leg. The implanted flexible biological electrode is suitable for treating lower limb behavior disorder diseases caused by hemiplegia in clinical medicine.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an implantable flexible bioelectrode and a manufacturing method thereof. Background technique [0002] Along with the change of dietary structure, the morbidity rate, mortality rate and disability rate of hemiplegia all increase year by year, have become one of the diseases that seriously endanger human life and health, and our country is wherein the country most seriously affected by hemiplegia. As our country enters an aging society, the number of elderly patients with hemiplegia caused by stroke is increasing day by day. According to the statistics of the World Health Organization, more than 10 million patients in my country suffer from hemiplegia every year. Modern medical treatment of hemiplegia usually adopts acupuncture, plaster, injection of western medicine, oral administration of traditional Chinese medicine and other treatment methods. These treatme...

Problems solved by technology

Modern medical treatment of hemiplegia usually adopts acupuncture, plaster, injection of western medicine, oral administration of traditional Chinese medicine and other treatment methods. These treatment methods only relieve symptoms, and the treatment and improvement of symptoms are not complete. Most patients gradually develop intractable sequelae.

Severe hemiplegia patients completely lose half of their limbs or completely lose their ability to move, which seriously affects the quality of life of the patient and brings a heavy burden to the family and society.
