The base and the two extension members are structured for connection to a plurality of struts which may be variably and selectively disposed in interconnecting relation to the ankle stabilization area and/or other portions of the external fixator assembly. | 01-29-2015 |
20150133933 | ROD COUPLER WITH VARIABLE ANKLE POSITION - The rod coupler according to the present invention comprises two clamping jaws and locking means for locking said clamping jaws against one another. Each clamping jaw comprises an outside surface and a clamping surface, the latter providing at least a first and a second groove. Each groove runs laterally from a different part of the outside surface extending into the rod coupler, wherein longitudinal axis of the first groove and the second groove include an angle that is equal to or less than 160 degrees. Opposing grooves form an aperture. The apertures are adapted for receiving a rod if the locking means is released. Clamping jaws that are locked by the locking means clamp the rods received in said apertures. | 05-14-2015 |
20150351800 | MULTI-LOCKING EXTERNAL FIXATION CLAMP - A clamping device for attaching to an external fixation element of an external fixation system includes a first jaw having an inner surface and an outer surface and includes a second jaw having an inner surface and an outer surface, with the inner surface of the first jaw and the inner surface of the second jaw together forming a passage configured to receive the external fixation element of the external fixation system. A locking system is engageable with the first and the second jaws. A portion of the locking system is moveable relative to the first and the second jaws between a first position where the locking arrangement is configured to prevent release of the external fixation element having a first size from between the first jaw and the second jaw and a second position where the locking arrangement is configured to prevent release of the external fixation element having a second size from between the first jaw and the second jaw. | 12-10-2015 |
20160022315 | EXTERNAL FIXING DEVICE, FOR TREATING BONE FRACTURES - An external fixing device for the treatment of bone fractures includes a first member, a second member, a central body arranged between the first member and the second member, a first ball joint for the articulated connection of the first member with the central body, a second ball joint for the articulated connection of the second member with the central body, locking means operatively associated to the first ball joint and with the second ball joint, respectively, the locking means being suitable for allowing/preventing the articulation of the first member and second member with respect to the central body, wherein the first member includes a first clamp, the second member includes a second clamp and the central body includes a third clamp for connection of the external fixing device to respective fractured bone portions to be treated. | 01-28-2016 |
20160066955 | IMPROVED EXTERNAL FIXATORS - A resilient external fixator between first and second bone portions includes a spring | 03-10-2016 |
20160089194 | TRANSOSSEOUS RIBBON WIRE DEVICES AND A SYSTEM AND METHOD FOR USING THE DEVICES - Devices for use in performing external fixation orthopedic surgery are provided. More particularly, a specialized transosseous wire having a rectangular cross-section is provided. The specialized wire is installed using a reciprocating motion. Thereafter, the specialized transosseous wires are affixed to a frame. Methods of using the transosseous wire are also disclosed. | 03-31-2016 |
20160095625 | ANATOMIC EXTERNAL FIXATION SYSTEM - A system includes a first fixation component, a second fixation component, and a first fastener. The first fixation component includes a first pivot structure including a first engagement surface and a first engagement feature, and can support one or more first clamping devices that secure bone pins inserted within a first bone. The second fixation component includes a second pivot structure including a second engagement surface configured to engage the first engagement surface, and is configured to support one or more second clamping devices that secure bone pins inserted within a second bone. The first fastener is configured to couple the first pivot structure to the second pivot structure and includes a first fastening element including a second engagement feature configured to engage the first engagement feature to maintain a first angle between a first axis of the first fixation element and a second axis of the second fixation element. | 04-07-2016 |
20220133356 | CLAMPING DEVICES FOR EXTERNAL FIXATION DEVICE - A clamping system includes a first clamp body including a first jaw, a second jaw, and a first aperture configured to receive a bone pin, the first clamp body is configured to receive a first connector rod between the first jaw and the second jaw, a second clamp body coupled to the first clamp body and including a third jaw, a fourth jaw, and a second aperture configured to receive the bone pin, the second clamp body configured to receive a second connector rod between the third jaw and the fourth jaw, and a securing assembly movable between a first position and a second position, such that moving the securing assembly from the first position to the second position reduces a distance between the first jaw and the second and reduces a distance between the third jaw and the fourth jaw. | 05-05-2022 |
