A navigable probe system and method of use is provided.The system may include a handle assembly having a lockingmechanism enclosed and a stylus, a cannula, and a trackingdevice extending from the handle assembly. Thestylus mayinclude undercuts for receiving pins of the locking mechanism.A cam of the handle assembly may rotate such that in a firstposition, the pins of the locking mechanism may be engagedwith the undercuts and in a second position, the pins of thelocking mechanism may be disengaged from the undercutsreleasing the stylus from the locking mechanism. Thestylusmay be slidably engaged with an inner diameter of the cannula.In some arrangements, the handle assembly may include a quickconnect system that in a first position attaches the cannulato the handle assembly and in a second position releases thehandle assembly and thus stylus from the cannula.
