Description

Auxiliary tool Technical Field The utility model relates to the technical field of medical instruments, in particular to an auxiliary tool. Background Deep brain stimulation (Deep Brain Stimulation, DBS for short) is used as an important nerve regulation and control treatment means and is widely applied to clinical treatment of nervous system diseases such as Parkinson's disease, epilepsy and the like. The core components include electrode leads implanted in the brain, pulse generators (Implantable Pulse Generator, abbreviated as IPGs) implanted in the chest, and extension leads connecting the two. In the operation process, the electrode lead is accurately implanted into a target brain region through a stereotactic technology, the IPG is embedded under the chest skin of a patient, and the electrode lead and the IPG form an electric signal transmission path through the extending lead. The two ends of the extension lead are respectively connected with the electrode lead and the IPG channel, and the reliable contact between the contacts is relied on to ensure the conduction of the circuit.
