Abstract
A suction delivery system for removing surgical smoke from an operative site includes a hose having the configuration of a first tube and adapted to extend generally between a suction source and the operative site. A wand coupled to the distal end of the hose has the configuration of a second tube with first portions of the wand define a major suction inlet while second portions of the wand define a lateral opening which relieves suction pressure when the major inlet is blocked by tissue. A tip section of the wand includes a vane extending at least partially across the major opening and a strut extending to support the vane outwardly of the major opening. The tip section also includes means providing a laterally visible indication of the degree of contamination of the system.
