AI Technical Summary

Technical Problem

Traditional DBS electrodes cannot obtain angle information of the stimulation end of the electrode wire after implantation in the human body, making it impossible to conveniently control the segmented contacts in a specific direction.

Method used

An electrode wire is designed with a radiopaque component, including a first marking part and a second marking part. The orientation of the electrode sheet is identified by X-ray imaging and CT technology. The radiopaque component includes marking holes and a display film. The angle of the electrode sheet is determined using X-ray radiopaque images and CT images.

Benefits of technology

It improves the success rate of surgery, reduces the number of radiological examinations for patients, lowers surgical costs, enhances ease of operation, and allows for convenient control of electrode pads in specific directions.

Abstract

This application relates to the field of medical product technology, disclosing an electrode lead, a stimulation system, and a method for identifying the orientation of electrode pads. The stimulation section of the electrode lead is provided with a imaging marking component, which has a first marking portion and a second marking portion connected to each other along the axial direction of the electrode lead. The first marking portion has at least one through-hole, through which the angle of the imaging marking component can be marked in the X-ray imaging image. The second marking portion includes two imaging films extending along the axial direction of the electrode lead, the two imaging films being arc-shaped and circumferentially spaced. A first notch is provided between the circumferentially close ends of the two imaging films, and a second notch is provided between the circumferentially opposite ends of the two imaging films. The first notch is smaller than the second notch. This application allows for the naked eye to obtain the orientation information of the electrode pads using both X-ray imaging and CT technology, improving operational convenience.
