A single use integrated disposable rotational speed reduction assembly having a shaft assembly, a housing, an output assembly, and a plurality of planetary gears each having a plurality of gear teeth. The shaft assembly is configured to cause rotation of the planetary gears with a sun gear. The rotation of the planetary gears is configured to cause rotation of an output shaft, with a reduction of rotational speed relative to the rotation of the shaft assembly. One or more gear components or spacers can be configured to fail after a predetermined number of use cycles.

The present disclosure relates to a powered screwdriver. The powered screwdriver includes a housing, a motor housed in the housing and a tool holder driven by the motor. The tool holder selectively holds both a screwdriver bit and a hex key. The hex key includes a bend such that legs of the hex key are transverse to one another.

Methods and apparatus to remove frangible fastener remnants are disclosed. A disclosed example apparatus to install a frangible fastener includes a drive tool having a drive socket operable to rotate a separable nut portion of the frangible fastener, and a fastener interface defining an interior for receiving at least the nut portion, the fastener interface being disposed on a drive end of the drive tool, where the drive socket is movable within the fastener interface and operable to rotate the frangible fastener, and where the separable nut portion of the frangible fastener is removed when the frangible fastener is installed. The apparatus also includes a nut-portion removal tube depending from the interior of the fastener interface, and a vacuum generator in fluid communication with the removal tube and configured to cause the separable nut portion to be removed from the interior and through the removal tube.

A system and method and fastening tool that utilizes ultrasonic or acoustic energy and a horn that focuses the energy into the fastener at a predetermined location in order to facilitate tightening or loosening the fastener.

The disclosed subject matter relates to a visual guide for aiding the surgeon in the insertion of a k-wire. The guide including a ring for receiving a guide wire, the guide wire extending from the ring parallel to the center axis of the ring; and, a ring attachment mechanism configured to attach the visual guide to a wire driver. The guide wires representing the trajectory of the k-wire in two orthogonal planes thus allowing the surgeon to free hand the insertion by visually referencing the guide wires and the actual trajectory of the k-wire within the bone.

A method of providing cueing signals to a user of a tool. Engagement sensors are positioned, for obtaining engagement data regarding the user's engagement with the tool. The engagement data is compared to a preselected acceptable range of engagement data. If the engagement data is outside the preselected acceptable range of engagement data, then an alert signal is transmitted to an alert device. Upon receipt of the alert signal, the alert device generates a cueing alert signal to indicate that the engagement data is outside the preselected acceptable range.
