The invention discloses a flexible bending minimally invasive tungsten needle electrode scalpel and a production method thereof. The cutter head of the flexible bending minimally invasive tungsten needle electrode scalpel is in a needle tip shape; an electrode diameter is of 1.5 to 2 mm; and the minimum needle tip diameter Phi is less than 20 [mu]m; the bleeding volume of an 8-cm incision surgeryof human body is less than 0.1 g; thermal burning loss is less than 2 g; knife edge adhesion is less than 0.5 g; the burning loss rate after a burning test at the current of 50 A for 20 min is less than 5 mg; and flexible bending of a needle bar is from 0 to 180 degrees. The flexible bendable minimally invasive tungsten needle electrode scalpel can realize fine cutting, less trauma, less blood loss, ablation resistance and durability, thereby providing a safe and reliable surgery electrode material for manufacturing high-end minimally invasive surgical instruments.
