Abstract: A bone nail apparatus includes a bone nail, a light source unit and a focalizing unit. The bone nail has a tube wall and at least one through hole. The tube wall is enclosed to form a receiving space. The at least one through hole extends through the tube wall and communicates with the receiving space. The light source unit includes a light emitter and at least one light transmission tube. The at least one light transmission tube is connected to the light emitter and receives a light therefrom. The at least one light transmission tube is received in the receiving space of the bone nail. Each light transmission tube has a light-outputting end aligned with a respective one of the at least one through hole. The focalizing unit has a light-receiving face facing one of the at least one through hole.
