This electric-stimulation spasm point location syringe pinhead contains: metallic pinhead, plastic pin cap, and electric stimulation. Its characteristics are: the outer surface of the metallic pinhead is coated with insulation material Teflor, but the inner surface doses not do insulation treatment; the plastic pin cap is made of innoxious and degradable plastic, and inside the pin cap there is a electric stimulation terminal near metallic pinhead; the electric stimulation terminal is fixed by circling screw in to prevent the terminal from running down, and the terminal is interconnected with electrolyte in pin when injecting, thereby translate the conductance to the metallic pinhead. |
