Abstract
Suction-irrigation apparatus for medical use in relation to wound and surgical sites comprises a probe projecting from a handpiece which also carries a valve, there being a through-conduit opening at the probe tip for suction, a first irrigation conduit opening at the tip, and a second irrigation conduit communicating with the suction conduit adjacent the tip, and with the valve normally operable to control the flow of fluid through the irrigation conduits. Preferably the valve operation has a normal position with both irrigation conduits closed, a fully operated position with only the first such conduit open, and a partially operated intermediate position with only the second such conduit open.
