Abstract
A coupling device for coupling a bone anchor to a rod includes a receiving part having a longitudinal axis, a channel for receiving a rod, and an accommodation space for holding a head of a bone anchor, a pressure member having a first portion for holding and clamping the head and a deformable portion with a free end, and a locking member. The pressure member is expandable for inserting the head and adjustable to lock the head. When the deformable portion is at a first configuration, the free end of the deformable portion is supported by the receiving part, and at least part of the locking member is movable to exert a force on the deformable portion for adjusting the deformable portion to a second configuration where at least part of the deformable portion is farther away from the longitudinal axis compared to the first configuration.
