Abstract
A coupling device for coupling a rod to a bone anchor includes a receiving part having first and second ends, a central axis, and two legs defining a recess at the first end for receiving the rod, a pressure member configured to exert pressure on an inserted head, and an actuating member with an engagement surface configured to engage the pressure member. When a first portion of the actuating member moves axially in a first direction, the engagement surface is configured to move from a first axial position to a second axial position to adjust the pressure member from a non-locking position where the head is pivotable to a locking position where the head is locked. When a second portion of the actuating member moves in the first direction, the pressure member is adjusted from the locking position back to the non-locking position.
