Disclosed is a deep brain stimulation electrode, comprising at least two sets of output electrode contacts, and each set of output electrode contacts is at least provided with one output electrode contact. After installation, at least one output electrode contact of the first set of output electrode contacts is located at the nucleus accumbens septi part of the brain； after installation, at least one output electrode contact of the second set of output electrode contacts is located at the anterior limb of the internal capsule part of the brain. Further disclosed are a deep brain stimulation device comprising the electrode and a deep brain stimulation method for detoxification treatment. In the present invention, an electrode simultaneously stimulates the dual function zones of the nucleus accumbens septi and the anterior limb of internal capsule, and can selectively stimulate different intracerebral function zones, thus improving the effectiveness and safety of the deep brain stimulation in treating mental diseases such as drug addiction detoxification, obsessive-compulsive disorder, and depressive disorder.
