Alignment jig for a bone fixation device

摘要

A jig for a bone fixation device, including those that comprise a guide; and a connecting element reversibly engagable with the bone fixation device; wherein the guide defines a non-rectilinear path and is adapted to receive the connecting element; and wherein the connecting element is remotely operable, and is adapted to permit a tool to be engaged with the bone fixation device. Other embodiments of the present invention include methods for placing a bone fixation device in a bone, using a jig of the present invention comprising the step of reversibly engaging the bone fixation device with the jig.

主权项

1. A jig for a bone fixation device, the jig comprising a guide; and a connecting element reversibly engagable with the bone fixation device; wherein the guide defines a non-rectilinear path and has a hollow cylindrical body and first and second open ends to allow the passage of the connecting element therethrough; and wherein the first end of the guide is in non-parallel orientation with respect to the second end of the guide; and wherein the connecting element is remotely operable, and is adapted to permit a tool to be engaged with the bone fixation device; and wherein the connecting element comprises an actuator arranged for rotational motion relative to the guide; and wherein the actuator comprises a hollow cylindrical body, which is, in use, co-axial with, and extends between the first and second ends of, the guide and wherein the actuator comprises at least two segments, which are each arranged for reciprocal movement relative to the other segment with respect to the longitudinal axis of the actuator, and wherein each segment is crenulated and comprises crenels arranged to receive crenels of an adjacent segment.
