20150305776 | DYNAMIZATION MODULE FOR EXTERNAL FIXATION STRUT - The present disclosure relates to an external fixation apparatus comprising a strut having a longitudinal axis defined therein, the strut comprising a strut housing having a housing adjustment aperture, an adjustment sleeve slidably disposed within the strut housing, and a fastener that releasably couples the strut housing with the adjustment sleeve. An embodiment of the adjustment sleeve comprises a first and a second bore extending from a top towards a bottom surface of the adjustment sleeve, a first sleeve member with a proximal end, a distal end, and an axial bore, and a second sleeve member adjoining the first sleeve member. In an embodiment, the second sleeve member comprises a body and a beveled end that is slidably disposed within the axial bore of the first sleeve member. The adjustment sleeve further comprises a biasing mechanism between the first sleeve member and the second sleeve member. | 10-29-2015 |
20150305777 | BONE TRANSPORT EXTERNAL FIXATION FRAME - Disclosed herein are systems and methods for manipulating the orientation of a plurality of bone fragments with respect to one another. A bone transport frame including first and second rings, a plurality of elongate struts, and a plurality of ring transport assemblies for orienting a first bone segment with respect to a second bone segment is disclosed. A third ring may be included in the bone transport frame for orienting a third bone segment with respect to the first and second bone segments. Manipulation of an adjustable member of the bone transport frame can transport a ring in either a proximal or distal direction with respect to other rings of the frame. Manipulation of another adjustable member of the bone transport frame can translate a central axis of one of the rings either toward or away from the central axes of the plurality of elongate struts. | 10-29-2015 |
20150313641 | FAST ADJUST EXTERNAL FIXATION CONNECTION ROD - The present disclosure provides various embodiments of an external fixation connection rod having articulatable joints that can be attached to external supports, such as rings. In some embodiments, the fixation connection rod includes a telescopic rod and connecting mechanisms for coupling the joints of the connection rod to the external supports. and the connecting mechanisms are operable to substantially lock the orientation of the joints. In some other embodiments, the connection rod includes a housing having parallel axial bores defined therethrough and sleeves slidably disposed in the axial bores. Also included in the present disclosure are methods of maintaining the orientation of first and second fixator rings for immobilizing bone segments. | 11-05-2015 |
20160000465 | COLLAPSIBLE FIXATOR SYSTEM - A collapsible fixator system comprising a first frame member and a second frame member and at least one strut. Each frame member comprises an upper surface, a lower surface, and a plurality of apertures extending from the upper surface to the lower surface. Each of the at least one struts comprises first and second strut connectors, such that the first and the second strut connectors are operable to releasably connect the strut to the first frame member and the second frame member. When the first and second strut connectors are in a first, collapsed position, the strut is releasably positioned substantially parallel to the upper and lower surfaces of the first and second frame members. When the first and second strut connectors are in a second, erect position, the strut may be fixedly positioned such that the first and second frame members are spaced apart from one another. | 01-07-2016 |
20160022314 | EXTERNAL BONE FIXATION DEVICE - The present application discloses embodiments related to an external bone fixation device configured to correct bone deformities or repair bone injuries. The device can include a plurality of bases configured to be attached to portions of a bone and a plurality of struts configured to be adjustable in length to change the position and orientation of the plurality of bases and the attached bone portions. | 01-28-2016 |
20160030085 | EXTERNAL FIXATOR STRUT - The present disclosure provides an external fixation strut for an external fixation device having a ball joints that can be attached to the outer or inner surface of the ring and locked to increase overall stability of the external fixation device. Some embodiments of the fixation strut include a first ball joint coupled to a first end portion of a strut housing, the strut housing having an axial bore defined therethrough. A second ball joint is coupled to a second end portion of an elongated member. The elongated member is coupled to an adjustment mechanism, which is coupled to an upper end portion of an adjustment sleeve. The adjustment sleeve is slidably disposed in the axial bore of the strut housing, and is used to effect coarse strut length adjustments. Gradual strut adjustments are effected by translating the elongated member. | 02-04-2016 |
20160066956 | External Fixation System - In embodiments of the invention, there is provided an external fixation system comprising a first plate and a second plate and connectors therebetween. Some or all of the connectors may be adjustable in length or angular position or both. Angular adjustment may comprise a fixed amount of friction and an adjustable amount of friction, and the permitted angular deflection can vary around the perimeter of the angular joint. An adjustable-length connector may comprise a tiltable nut that can either engage or not engage a threaded rod to provide both coarse adjustment and fine adjustment. Tactile or audible feedback may be provided. | 03-10-2016 |
