External fixing device, for treating bone fractures

An external fixing device for the treatment of bone fractures comprising a first member, a second member, a central body arranged between said first member and said second member, a first ball joint for the articulated connection of said first member with said central body, a second ball joint for the articulated connection of said second member with said central body, locking means operatively associated with said first ball joint and said second ball joint, said locking means being designed to allow/prevent the articulation of said first member and second member respectively, with respect to said central body, wherein said first member comprises a first clamp, said second member comprises a second clamp and said central body comprises a third clamp, wherein said first clamp, said second clamp and said third clamp are suitable for housing pins or screws, to ensure the connection of said fixing device to the bone portions to be treated, wherein said first clamp is associated in a moveable manner to said first member along a longitudinal direction (A, B), and said second clamp is associated in a moveable manner to said second member along a longitudinal direction (A′, B′), wherein said external fixing device comprises means for adjusting the position of at least one of said first clamp along said first member and the position of said second clamp along said second element, and wherein said adjustment means comprise an adjustment screw longitudinally oriented along said first member and associated with a base portion of said first clamp by a screw-and-nut type coupling, and a further adjustment screw longitudinally oriented along said second member and associated with a base portion of said second clamp by a screw-and-nut type coupling, wherein the position of said first clamp along said first member and the position of said second clamp along said second member is adjusted by rotating a respective of said adjustment screws.
