A surgical navigation probe assembly (700, 900) comprising: a receiver (702, 902) having: a receiver channel (706, 906) extending in a longitudinal direction and configured to receive a navigation probe shaft in a proximal open end of the receiver channel, and limit movement of the navigation probe shaft in a lateral direction that is perpendicular to the longitudinal direction, and a first threaded surface (712, 908); and a lock (714, 914) having: a central passage extending in the longitudinal direction, and a second threaded surface; wherein the lock and receiver are movable between a first configuration in which the lock and receiver allow the navigation probe shaft to move relative to the lock and receiver along the longitudinal direction, and a second configuration in which the lock and receiver prevent the navigation probe from moving relative to the lock and receiver along the longitudinal direction; and, wherein the lock is rotatable relative to the receiver to engage the first threaded surface with the second threaded surface to thereby move the lock and receiver between the first configuration and the second configuration. a receiver (702, 902) having: a receiver channel (706, 906) extending in a longitudinal direction and configured to receive a navigation probe shaft in a proximal open end of the receiver channel, and limit movement of the navigation probe shaft in a lateral direction that is perpendicular to the longitudinal direction, and a first threaded surface (712, 908); and a receiver channel (706, 906) extending in a longitudinal direction and configured to receive a navigation probe shaft in a proximal open end of the receiver channel, and limit movement of the navigation probe shaft in a lateral direction that is perpendicular to the longitudinal direction, and a first threaded surface (712, 908); and a lock (714, 914) having: a central passage extending in the longitudinal direction, and a second threaded surface; wherein the lock and receiver are movable between a first configuration in which the lock and receiver allow the navigation probe shaft to move relative to the lock and receiver along the longitudinal direction, and a second configuration in which the lock and receiver prevent the navigation probe from moving relative to the lock and receiver along the longitudinal direction; and, wherein the lock is rotatable relative to the receiver to engage the first threaded surface with the second threaded surface to thereby move the lock and receiver between the first configuration and the second configuration. a central passage extending in the longitudinal direction, and a second threaded surface; wherein the lock and receiver are movable between a first configuration in which the lock and receiver allow the navigation probe shaft to move relative to the lock and receiver along the longitudinal direction, and a second configuration in which the lock and receiver prevent the navigation probe from moving relative to the lock and receiver along the longitudinal direction; and, wherein the lock is rotatable relative to the receiver to engage the first threaded surface with the second threaded surface to thereby move the lock and receiver between the first configuration and the second configuration.
