Patent number: 11076890Abstract: Various rod-to-rod connectors having robust rod closure mechanisms and related methods are disclosed herein, e.g., for enhancing the locking or clamping force on a rod. An exemplary connector can provide a robust closure mechanism for rod-to-rod connections in which the run-on length of a rod slot is minimal. The connector can include a moveable jaw that is partially disposed within a connector body and configured to pivot or translate relative to the connector body to form a fully or substantially closed rod slot around a first rod. The closed rod slot can be formed between a first rod-receiving recess defined in the connector body and a counterpart first rod-receiving recess defined in the moveable jaw. The locking or clamping force of the moveable jaw can be amplified by a mechanical advantage caused by the force exerted to lock a second rod in a second rod-receiving slot of the connector body.Type: GrantFiled: December 1, 2017Date of Patent: August 3, 2021Assignee: Medos International SàrlInventors: Aubrey Ortiz, Kevin Lee, Frank Spratt, Robert Carruth, Samuel Jacobs, Mark Hall
