Abstract: Techniques and instrumentation for elbow reconstruction, specifically, for repairs of the ulnar collateral ligament (UCL). The instrumentation provides for precise formation of sockets and tunnels along with easy suture/graft passage while accommodating all forms of elbow UCL reconstruction techniques. A V-drill guide is provided with a handle and two drill sleeves having intersecting trajectories for creating an intersecting V-shaped bone tunnel in the ulna. An adjustable humeral guide has an adjustable arm with an arc shape, and a peg and a block extending from each end of the adjustable arm. The peg is shaped to fit within an already-formed humeral socket. The block allows a drill to pass through and form other tunnels which intersect with the originally-formed tunnel at various positions.

Abstract: An overload relay trip mechanism includes a housing, a reset button, a leaf spring, a test button, a coil spring, and an actuator. The reset button can be actuated from a normal position to a reset position to cause the leaf spring to transition from a first position to a second position, which causes a reset actuator-engaging element to move the actuator from a tripped position to a closed position. The test button can be actuated from a normal position to a test-stop position to cause a first test actuator-engaging element to move a moveable contact from an electrically connected position to an electrically disconnected position. The test button can further be moved from the test-stop position to the test-trip position to cause a second test actuator-engaging element to move the actuator from the closed position to the tripped position.

Abstract: A method for conducting nondestructive internal inspection of a rotary drill bit used for drilling subterranean formations comprises communicating ultrasonic waves into a drill bit and detecting ultrasonic waves that are reflected by at least a portion of the drill bit.
