Abstract:
1. An assembly comprising: a sharp defining an outer diameter and a longitudinal axis, the sharp has a notch with a first shoulder and a second shoulder that are perpendicular or substantially perpendicular to the longitudinal axis, the notch extending along the longitudinal axis; a shield; and a disk-like lock having a main body portion that forms an outer frame and radially-inwardly directed compression springs that have outer ends attached to the main body and inner ends that define a central opening through which the sharp extends, the compression springs being radially-inwardly directed perpendicular or substantially perpendicular to the longitudinal axis of the sharp to provide an abutting interaction with both the first shoulder of the notch to prevent unwanted proximal movement of the sharp relative to the shield and the second shoulder of the notch to prevent unwanted distal movement of the sharp relative to the shield, the interaction being effective regardless of the rotational orientation of the sharp.
