Abstract
Abstract Surgical suction mat including a rib, or the like, pliable member of a predetermined geometrical shape, a longitudinal cylindrical hose connected to the plurality of holes and being of a finite length including a suction hose connecton at the other end where the rib design with the holes provides suction to remove fluids oriented at an angle to the suction ports. The longitudinal cylindrical hose can include a parallel wire hose or the like to maintain a predetermined position. The ribbed design or the like of the pliable member allows drainage of fluids and lifts vessels, tissue or the like above the fluids. The ribbed pliable member is preferably opaque blue as a preferred color for working in a body tissue environment. The suction hose can be encompassing within the pliable member. The surgical suction mat can also be made of porous material with or without ribs.
