CLAMPING APPARATUS FOR EXTERNAL FIXATION AND STABILIZATION

摘要

Clamping devices and methods for external fixation systems include a post component having a yaw axis and a clamping system secured to the post component and rotatable about the yaw axis. The clamping system includes a outer jaw and a inner jaw having an inner surface facing the outer jaw. The outer and inner jaws together form an opening for receiving a fixation element of the external fixation system. The inner jaw and outer jaw have a roll axis alignable with a longitudinal axis of the fixation element. The clamping system and post component are rotatable about the roll axis. The inner jaw also includes a cylindrical outer-facing surface. The devices also include a base component having a cylindrical concave surface having a pitch axis. The concave surface of the base component interfaces with the cylindrical outer facing component on the inner jaw. The outer and inner jaws being rotatable relative to the base and the post component about the pitch axis.
