Abstract
A suction device is shown and described. The suction device includes a body, an input port configured to receive a flow of matter, a suction port, and a suction lumen that couples the suction port to the input port. In some embodiments the suction device is configured to couple with a surgical instrument for use in a surgical procedure.
Claims17
A device comprising:
- a body having an outer surface and an inner surface, and configured to couple with an electrosurgical instrument and provide suction to a surgical field, the body comprising:
- a. a longitudinal channel having a first end having a first diameter, a second end having a second diameter, and a narrowing positioned between the first end and the second end and having a third diameter which is smaller than the first diameter and the second diameter;
- b. an input port positioned at the first end and configured to receive a suction flow;
- and
- c. an intake port having a first opening positioned on the outer surface and a second opening position on the inner surface;
- wherein the first opening is positioned between the first end and the second end and configured to intake a flow of matter;
- wherein the second opening is positioned to open into the narrowing so that the intake port is in fluid communication with the narrowing, and so that a velocity of the flow of matter received into the intake port increases when the suction flow passes through the narrowing.

- a body configured to couple with an electrosurgical instrument and provide suction to a surgical field, the body comprising:
- a longitudinal channel having a first end and a second end;
- an input port at the first end of the longitudinal channel for receiving a suction flow;
- one or more intake ports positioned between the first end and the second end of the longitudinal channel and configured to intake a flow of matter;
- one or more narrowings in fluid communication with the one or more intake ports and positioned to receive the flow of matter from the one or more intake ports so that the flow of matter increases in velocity as the matter passes through the one or more narrowings;
- and
- an emulsion segment positioned to receive the flow of matter.
