Claims24
A method comprising
- directing a suction flow through an input port of a body configured to couple with an electrosurgical instrument, wherein the body comprises a distal end and a proximal end and a narrow segment positioned between the distal end and the proximal end, wherein the input port is positioned at the distal end, wherein one or more intake ports are positioned at the distal end, and wherein the one or more intake ports are positioned so that they are in flud communication with the narrow segment;
- directing the suction flow through the narrow segment so that a velocity of the suction flow is increased as the suction flow passes through the narrow segment;
- and
- directing a flow of matter through the one or more intake ports, wherein a velocity of the flow of matter through the one or more intake ports is increased by a Venturi effect that is generated when the suction flow passes through the narrow segment, wherein the body comprises an emulsion segment positioned to receive the flow of matter.
