Abstract
A surgical suction system and method includes a source of suction and a conduit having a distal end and a proximal end. At its distal end, the conduit has a diameter not greater than about 5/8 inch to provide limited access to the surgical site and an inside diameter not less than about 1/4 inch to accommodate the bone fragments in the waste slurry. A coupling is provided for connecting the proximal end of the conduit to the suction source in order to provide suction at the distal end of the conduit at a velocity not less than about ninety miles per hour. A fluid containment vessel can be connected between the conduit and the source of suction to provide a liquid trap for the waste slurry passing along the conduit. An associated method includes the step of activating the suction source to provide suction at the distal end of the conduit with a velocity not less than ninety miles per hour.
