1. A device for implantation to reduce sleep apnea, comprising:
a worm drive assembly, including:
a worm having a longitudinal axis and a spiral thread positioned on a surface of the worm along the longitudinal axis; and
a worm wheel rotatably coupled to the worm, wherein teeth of the worm wheel engage with the spiral thread of the worm and the worm wheel has a rotation axis that intersects the longitudinal axis of the worm;

a pull line fixing device fixedly positioned on a first surface of the worm wheel and configured to rotate with the worm wheel about the rotation axis simultaneously, the pull line fixing device including a fixing through hole and a line slot, wherein a center line of the fixing through hole is crossed with the line slot in a three-dimensional manner and the center line of the fixing through hole is perpendicular to the line slot; and
a pull line connected to the pull line fixing device by securing the pull line to the pull line fixing device via the fixing through hole and the line slot, wherein:
during operation of the device, a rotation of the worm about the longitudinal axis causes (i) a corresponding rotation of the worm wheel and the pull line fixing device about the rotation axis and (ii) a winding/unwinding of the pull line on the pull line fixing device, thereby adjusting a tension of the pull line.
