Referring to FIGs. 9A and 9B, the navigation guide 900 includes a longitudinal axis 940 and a coupler 942 between the proximal end 902 and the distal end 904. The coupler 942 is configured to hold or keep the proximal end 902 and the distal end 904 together until a user operates the coupler 942 to separate the proximal end 902 and the distal end 904. Thus, the coupler 942 can temporarily hold the proximal end 902 and the distal end 904 and also release the proximal end 902 and the distal end 904 when needed. Those of skill in the art will appreciate that the coupler 942 can be implemented in a variety of ways using a variety of structures. In the illustrated embodiment, the coupler 942 implemented using a threaded shaft with a head and a driver and a set of holes in the body 906. At least one of the holes of the set of holes has internal threads configured to engage the external threads of the shaft.
