AI Technical Summary

Technical Problem

The existing methods for treating inflammatory bowel disease (IBD) have many adverse drug reactions, poor clinical efficacy, and traditional implantable sacral nerve stimulation devices require surgical implantation, which poses surgical risks and high costs.

Method used

An in vitro sacral nerve electrical stimulation system was designed, through directed guides and nerve electrical stimulation devices, a metal guidewire and pulse emitter were used to achieve minimally invasive and painless sacral nerve electrical stimulation, and a control terminal connected with Bluetooth was adjusted according to specific needs.

Benefits of technology

Non-surgical implantation is realized, reducing operational risks and costs, and can adjust stimulation parameters according to actual conditions, improving the accuracy and safety of treatment, which is suitable for home use and at home.

Abstract

The invention discloses an in-vitro sacral nerve electrical stimulation system, which comprises a directional guide piece and a nerve electrical stimulation device, the directional guide piece is embedded under the skin of a user and is integrally disc-shaped, the upper surface of the directional guide piece is downwards provided with a groove, the bottom end of the directional guide piece is connected with a metal guide wire, the metal guide wire is left in a sacral foramen, the nerve electrical stimulation device is externally arranged in vitro, and the nerve electrical stimulation device is fixedly connected with the directional guide piece. Corresponding to the position of the directional guide piece, a sharp needle matched with the groove is arranged at the bottom of the electrical nerve stimulation device, a pulse transmitter is arranged in the electrical nerve stimulation device, and a signal transmitted by the pulse transmitter is transmitted to the sacral foramen through the sharp needle and the metal guide wire so as to realize nerve stimulation. In-vitro sacral nerve electrical stimulation is accurately carried out in a non-surgical implantation mode, parameter adjustment can be carried out through an external program, operation is convenient, the risk is small, and the curative effect is outstanding.
