EXTERNAL FIXATOR SYSTEM

摘要

An external fixator system comprising at least two fixation plates which are arranged at a distance to each another, at least one adjustable length strut having a first end region and a second end region which are in connection with the fixation plates and at least one actuation unit to adjust the length of the strut in order to adjust the distance and/or orientation between the fixation plates. The actuation unit is in a fixed connection with at least one of the fixation plates as well as with at least one of the end regions of the respective strut in order to connect the strut with the fixation plate. The actuation unit comprises a feedback unit which provides the user with a feedback concerning the degree of the actuation.
