Abstract:
1. A lancer system comprising a lancer body assembly and an adjustment assembly, the adjustment assembly attachable to the lancer body assembly and comprising: an outer member, having a distal portion and a proximal portion, the distal portion having an exterior surface, an interior surface and an orifice, a portion of the outer member being rotatable with respect to the lancer body assembly; and an inner member, having a distal portion and a proximal portion, the distal portion having an interior surface, an exterior surface and an orifice; wherein the inner member is fully contained within the outer member and positioned relative to the outer member such that when the outer member is rotated, the inner member moves relative to the body assembly, thereby adjusting the distance between the orifice of the inner member and the orifice of the outer member; and wherein the outer member is prevented from axial motion relative to the body assembly.
