Abstract
A positioning mark apparatus of a surgery navigation system and an implementation instrument thereof are disclosed. The positioning mark apparatus includes a positioning base and a frequency modulated radio frequency positioning module. One end of the positioning base is a lock portion having a screw structure, another end is a head having a joint structure, and a free end of the head has a fitting structure. The frequency modulated radio frequency positioning module has a sleeving structure that cooperates with the head structure and buckles with the joint structure. The frequency modulated radio frequency positioning module includes an antenna unit, a printed circuit board unit electrically connected to the antenna unit, and an electronic component battery unit supplying power to the printed circuit board unit. The frequency modulated radio frequency positioning module may transmit, according to a received frequency modulated signal, a feedback signal including a radio frequency signal to the external.
