Abstract: A push shovel assembly facilitates pushing snow in a desired direction by permitting limited pivoting of a shovel blade in a selectable direction left or right during use. The assembly includes a blade and a pair of arms. Each arm has a lower end pivotally coupled to the blade. Each of a pair of wheels is rotatably coupled to an associated one of the arms. A brace is pivotally coupled to and extends between the arms. Each of a pair of stop pins is coupled to the brace proximate an associated one of the arms wherein pivoting of the brace relative to the arms is restricted by each stop pin when each stop pin abuts the associated arm.

Abstract: A disposable vascular tourniquet for controlling the constriction of a blood vessel during surgery. The vessel occluder comprises a flexible tubular sheath having a clamping structure disposed at its proximal end. The clamping structure is a unitary molded plastic part which has a tubular base portion adapted to be inserted into the proximal end of the flexible sheath and projecting from this base portion are bifurcated fingers, one of which includes a transversely extending latch portion which is adapted to mate with a recess on the other finger. A retractor or snare having a hook at one end and a ring-type handle at the other end may be inserted between the fingers of the clamp when in its unlatched condition and through the tubular base of the clamp and the sheath so as to extend outwardly from the distal end of the sheath. A cord may be looped around a vessel to be constricted and the ends of the loop are captured in the hook of the retractor.
