DEEP BRAIN STIMULATION
DBS is a surgical treatment in which a device called a neurostimulator delivers tiny electrical signals to the areas of the brain that control movement.
• Dystonia (肌张力障碍) • Essential tremor (特发性震颤) • Chronic pain (慢性痛) • Obsessive-compulsive disorder
(强迫性精神障碍) • Major depression (重度抑郁)
Chronic Pain
Dystonia
Ø Make another small opening behind the ear and passes the extension wire under the skin of the head, neck, and shoulder.
APPLICATIONS
DBS can also be used to treat the flowing conditions:
Essential Tremor
RISKS

THE OPERATION PROCEDURE
STAGE 1
Ø Your head is placed in a special frame using screws to keep it still during the procedure.
l Implant （植入）
COMPONENT
PROCEDURE
l DBS is essentially a pacemaker for the brain.
Description l The device sends electrical impulses to specific parts of the brain accordingly. l DBS directly changes brain activity in a controlled matter.
