<p>A needle depth stop (20, 120) which is side loading and configured to accommodate a wide range of needle diameters. The needle depth stop (20, 120) includes jaws (36, 38, 136, 138) which are biased closed and indexed into place by a spring member (26, 126), such as a "C" ring. However, the jaws (36, 38, 136, 138) can be pivoted open for receiving a needle (40) by pinching together two finger grip portions (32, 34, 132, 134), the opening force deceasing at a decreasing rate as a result of the pivot (99) translating toward the springs load center. The needle depth stop (20, 120) preferably provides approximately one pound of resistance to longitudinal displacement along the needle, and only one hand is required to position and lock the needle depth stop (20, 120) into place. In order to accommodate a wide range of needle diameters, the jaws (36, 38, 136, 138) include a plurality of grooves, each configured to accommodate a different range of needle diameters.</p> |
