A surgical irrigation device ( 10 ) consists of a continuous outer wall ( 12 ) and a continuous inner wall ( 11 ) which are held apart and inter-connected by one or more spacers ( 20 ). The upper edges ( 13 ), ( 15 ) of the inner and outer walls ( 11 ), ( 12 ) define an upper vacuum channel ( 17 ) and the lower extremities ( 14 ), ( 16 ) of the inner wall ( 11 ) and outer wall ( 12 ) a lower vacuum channel. A vacuum tube ( 22 ) leads from outside the body ( 10 ) into the space between the inner and outer walls ( 11 ), ( 12 ). An irrigation tube ( 23 ) passes from outside of the body ( 10 ), through both the inner walls ( 11 ), ( 12 ) so as to terminate within the central space defined by the interior wall ( 11 ) and an aspiration tube ( 25 ) which originates externally to the body passes through both the inner and outer walls ( 11 ), ( 12 ) at a different location to the irrigation tube ( 23 ).
