Electric nerve stimulation module and preparation method thereof

Abstract

The invention relates to an electric nerve stimulation module and a preparation method thereof. The electric nerve stimulation module comprises soluble adhesives, an electrode guide pipe and a puncture pipe, wherein the electrode guide pipe comprises a protecting pipe and a first fixing part, the first fixing part is composed of a first fixing unit and a first fixing wing, the first fixing unit isfixedly in the protecting pipe in a sleeve mode, the first fixing wing comprises a first fixed end and a first free end, the first fixed end is connected with one end of the first fixing unit, and the first free end is adhered to the protecting pipe through the soluble adhesives; the puncture pipe is arranged in a sleeve mode on the electrode guide pipe; when the electrode guide pipe is implantedinto a target tissue and reaches a target, the soluble adhesives in contact with body fluid can be gradually dissolved to lose viscosity, and then the first free end can automatically expand and be embedded into the target tissue to achieve fixation between the electrode guide pipe and the target tissue. The electric nerve stimulation module saves fixation of the fixing part through a pipe casingand accordingly solves the problem of great inconvenience caused by large force of friction between the pipe casing and an electrode guide pipe fixing structure to operation of doctors.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a nerve electrical stimulation electrode assembly and a preparation method thereof. Background technique [0002] An electrical nerve stimulation system is an active implantable medical device. Similar to the widely used cardiac pacemaker system, the nerve electrical stimulation system also consists of a pulse generator that generates stimulation signals and an electrode catheter that transmits stimulation signals. The electrode catheter is implanted in the patient, and the signal generated by the pulse generator stimulates the target nerve or nerve nucleus through the electrode catheter, and the nerve is regulated by electrical stimulation to achieve the purpose of treating or improving disease symptoms. To achieve long-term and stable therapeutic effect, it is necessary to keep the position of the stimulating contact point and the target point on the electrode catheter...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to provide a nerve electrical stimulation electrode assembly and a preparation method thereof for the problem that the friction between the cannula and the electrode catheter fixing structure is relatively large, which causes great inconvenience to the doctor's operation.
