Description

Novel implanted nerve stimulation needle electrode

Technical Field

The utility model relates to the technical field of extension leads, in particular to a novel implantable nerve stimulation needle electrode.

Background

The deep brain electrical stimulation therapy is characterized in that a stimulating electrode is inserted into a specific nuclear group in a brain through a stereotactic technology and a microelectrode recording technology, and the abnormal brain nuclear group discharge is inhibited through continuous high-frequency pulse electrical stimulation to achieve a treatment effect. Since the needle electrode is entirely implanted in the body, there are stretching and squeezing conditions, and the smaller the volume, the better the performance requirements. The existing nerve stimulation needle electrode has the defect that the outer diameter of the catheter is larger and the comfort of a patient is poorer due to the adoption of the mode of 1.3mm in the outer diameter.

SUMMERY OF THE UTILITY MODEL
