Abstract: A cleaning device for a surgical instrument can include a body; at least one passage extending through the body from a first open end of the body to a second open end of the body. The first and second open ends and the at least one passage can be dimensioned to receive and guide a shaft of a surgical instrument during a cleaning procedure. At least one aperture in flow communication with a port and the at least one passage can define a cleaning fluid path from the port to the passage.

Abstract: The present technology relates to a helmet of a layered and segmented design including impact attenuation structures. The helmet can include a series of layers that individually, or in combination, provide the necessary functions of the helmet. The helmet may feature a layer with a low coefficient of friction to act as a slip layer and slide due to rotational force. The present technology includes impact attenuation structures of predetermined geometries, layers, and materials to allow for an appropriate impact response with a certain degree of control over the buckling process and an adaptive impact response. The present technology of impact attenuation structures may be applicable where impact absorption and controlled buckling is desired, such as bike helmets.

Abstract: A blank etching apparatus is provided that positions an etching screen relative to a blank. The blank etching apparatus includes a worktable having a table top and a base. The table top has a pair of lateral sides and a pair of longitudinal sides. A first jig is movable with respect to the table top along an x-axis. The first jig includes a first pair of lateral segments and a first pair of longitudinal segments. A screen frame is received between the first pair of longitudinal segments and the first pair of lateral segments of the first jig. The screen frame is moveable relative to the first jig and the table top along a y-axis. The screen frame receives and carries the etching screen and cooperates with the first jig to accurately and repeatably position the etching screen relative to the blank.

Abstract: In accordance with at least one exemplary embodiment, a surgical instrument comprises a shaft comprising a distal end a proximal end, a wall extending from the distal end to the proximal end and having an exterior surface and an interior surface. At least a first portion of the shaft may include openings that penetrate the interior and exterior surfaces of the wall and provide flow communication from an exterior of the shaft to an interior of the shaft. At least one transverse cross-sectional plane and at least one longitudinal cross-section plane through the portion of the shaft including openings may each intersect multiple openings that penetrate the interior and exterior surfaces of the wall. The surgical instrument may include a manifold in flow communication with an interior of the shaft. The surgical instrument may include a flexible sleeve located inside the interior of the shaft.
