A surgical suction device which includes a first tubular section with a first inlet end and a first outlet end. The first tubular section has a variable inside diameter which continuously expands from the first inlet end to the first outlet end. A curved tubular section is connected to the first outlet end, and the curved tubular section has a second inlet end and a second outlet end. The curved tubular section further includes a second inside diameter which extends from the second inlet end to the second outlet end, where the second inside diameter is approximately constant from the second inlet end to the second outlet end. The second inside diameter is also not less than the variable inside diameter at the first outlet end.
