A handpiece for a surgical irrigator and suction device includes a drip-free valve arrangement in which the portion of the flexible irrigation conduit is kinked in a V-shape. The handpiece carries a suction wand and an irrigation wand. The wands are easily detachable from the handpiece and can be substituted for wands having other configurations. A retainer clip is provided to prevent inadvertent separation of the wands. The irrigation wand may be used with a debridement nozzle which emits a plurality of distinct irrigation streams in a plane which provides an approved degree of manipulative control for the irrigation procedure.
