Claim 0:
1. An implantable nerve stimulation device comprising:
a body part which is formed of a metal that transmits ultrasonic waves, and includes a stimulation surface and a charging surface facing each other;
a header part which is made of a non-metal and is located at one end of the body part;
a cover which includes a stimulation electrode, a hinge part rotatably coupled to one side of the stimulation surface, and a coupling part detachably coupled to the side of the stimulation surface opposite the hinge part, is positioned above the stimulation surface to interpose a nerve between the electrode and the stimulation surface;
power generation elements which are located inside the body part and are electrically connected to the electrode;
a first connection part which extends from the coupling part;
a second connection part which is provided at a connection point between the stimulation surface and the charging surface; and
a connection member which binds the first connection part and the second connection part,
wherein the first connection part includes a plurality of through-holes,
wherein a portion of the second connection part is spaced apart from the connection point, and has an insertion space between the portion of the second connection part and the connection point,
wherein the connection member includes a medical wire which continuously passes through at least one of the plurality of through-holes and the insertion space to bind and tighten the first connection part and the second connection part,
wherein the power generation elements generate power based on friction caused by ultrasonic waves penetrating the charging surface, and includes an inducer vibrating by the ultrasonic waves, an electrified body generating frictional electricity by friction with the inducer, and a spacer interposed between the inducer and the electrified body to mutually separate the inducer and the electrified body.
