| 20120095462 | External Fixation Surgical Clamp with Swivel - A clamping device for an external fixation system includes a first clamp having an opening for receiving an external fixation element, the first clamp having an axle seat. A first base component includes a concave first surface and a second surface facing away from the first surface. The concave first surface is in selective engagement with the clamp. A swivel element comprises an axle component and a post component. The axle component is disposed on the axle seat of the first clamp. The post component extends from the axle component and has a length sized to extend from the axle component through a second external fixation clamp. The post component is arranged to swivel relative to the axle seat. Methods are also disclosed. | 04-19-2012 |
| 20120089142 | Single Lock External Fixation Clamp Arrangement and Method - A clamping device for an external fixation system includes a post component having a yaw axis, a first clamp secured to the post component and rotatable about the yaw axis, and a second clamp secured to the post component and rotatable about the yaw axis relative to the first clamp. The device includes a tightening component configured in a manner that an action of tightening the tightening component simultaneously locks both the first and second clamps in a gripping arrangement and substantially eliminates their relative rotation about the yaw axis. Interdigitating components can be spaced apart by high spring rate biasing elements that so as to allow for smooth adjustment of the clamping device components relative to each other until the appropriate position is achieved and until after a sufficiently high clamping load has been applied. | 04-12-2012 |
| 20120004659 | 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. | 01-05-2012 |
| 20110313419 | Hexapod External Fixation System with Collapsing Connectors - An external fixation system includes a first base member configured to attach to a first bone segment and a second base member configured to attach to a second bone segment. A plurality of single DOF controlling elements extend between the first and second base members. The single DOF controlling elements include a crank arm having a strut interface and a base member interface, the crank arm having a first longitudinal axis and being pivotably disposed relative to one of the first and second base members. The single DOF controlling elements also include a strut extending from the strut interface toward one of the first and second base members. The strut has a second longitudinal axis, and the crank arm and strut are structurally configured so that the first and second longitudinal axes form a non-zero angle. | 12-22-2011 |
| 20110172663 | ARTICULATION APPARATUS FOR EXTERNAL FIXATION DEVICE - An articulation element consisting of a plurality of adjustable jaw pairs for the purposes of fixating the relative position of coupled bars and/or bone pins of an external bone fixator. Each of the adjustable jaws consists of a pair of hemispherical jaw elements contained within a spherical housing. A passage is eccentrically arranged through the jaw elements to accept the pin or bar. The jaw elements have interposed between them a spring element that serves to bias the jaw elements in the closed position. Pins serve to provisionally lock the jaw elements in the closed position. Spring loaded buttons act to release the pins thereby allowing the jaw elements to open accepting the pin or bar. The jaws are attached in a back to back fashion through the use of a threaded collar which acts as a turnbuckle pulling the jaws together when tightened. | 07-14-2011 |
| 20110103676 | METHOD FOR USING A FIXATOR DEVICE - A method for determining the proper configuration of a fixator or other medical device to correct a given deformity by solving the simultaneous equations representing the kinematic chain for the device. One skilled in the art would appreciate that x-rays, clinical evaluations, or a combination of both may be used to determine the distal and proximal mounting characteristics, including the use of digital x-rays with images from an imaging device to reduce or eliminate the needs for a physician to take measurements. The technique can be expanded to other medical evaluations. Additionally, one skilled in the art would appreciate that the method of the present invention could be written as one or more sets of instructions stored on a computer-readable medium that could be executed by a computer. | 05-05-2011 |
| 20110098707 | METHOD AND CLAMPING APPARATUS FOR EXTERNAL FIXATION AND STABILIZATION - Clamping devices and methods for external fixation systems include a post component having a yaw axis and a clamping system secured to the post component and rotatable about the yaw axis. The clamping system includes a outer jaw and a inner jaw having an inner surface facing the outer jaw. The outer and inner jaws together form an opening for receiving a fixation element of the external fixation system. The inner jaw and outer jaw have a roll axis alignable with a longitudinal axis of the fixation element. The clamping system and post component arc rotatable about the roll axis. The inner jaw also includes a cylindrical outer-facing surface. The devices also include a base component having a cylindrical concave surface having a pitch axis. The concave surface of the base component interfaces with the cylindrical outer facing component on the inner jaw. The outer and inner jaws being rotatable relative to the base and the post component about the pitch axis. | 04-28-2011 |

| 20100087819 | Forward Kinematic Solution for a Hexapod Manipulator and Method of Use - The present disclosure provides methods, systems, and computer program product for treating a fractured bone using a hexapod manipulator. The hexapod manipulator has a first ring and a second ring, with the first and second rings being connected by six telescopic struts. The method includes the steps of determining a current position of the second ring relative to the first ring; determining a desired position of the second ring relative to the first ring; and computing with a processing system the difference between the current position and the desired position of the second ring relative to the first ring using a linear approach to a nonlinear problem. | 04-08-2010 |
