Abstract:
1. A fixator system comprising: a first fixator base element; a second fixator base element; a first active strut connected between the first fixator base element and the second fixator base element, wherein the first active strut includes a joint comprising a driven element attached to the first fixator base element, a first drive system for rotating the driven element about a first axis of rotation, and a second drive system for rotating the driven element about a second axis of rotation, wherein the first and second axes intersect at a common point of rotation of the driven element; and a first passive strut connected between the first fixator base element and the second fixator base element; wherein the first passive strut is configured to be placed into a passive locked state such that the first passive strut is non-adjustable and resists relative positional changes between the first and second fixator base elements, and placed into an unlocked state such that the first passive strut freely allows relative positional changes between the first and second fixator base elements; wherein the first active strut is configured to be placed into an active locked state such that the first active strut resists relative positional changes between the first and second fixator base elements, and placed into an unlocked state such that the first active strut freely allows relative positional changes between the first and second fixator base elements; and wherein the first active strut is configured to allow for relative positional changes between the first and second fixator base elements while maintaining rigidity while the first active strut is in the active locked state.
