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 instr

대표청구항 ▼

1. 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; andc. 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. 2. The device of claim 1, wherein the width of the narrowing is adjustable. 3. The device of claim 1, comprising a suction port at the second end configured to couple with a suction source. 4. The device of claim 1, comprising a positive pressure port configured to receive a positive pressure gas flow so that the positive pressure gas flow generates an area of low pressure within the device through a Coanda effect, and wherein the area of low pressure generates the suction flow. 5. The device of claim 4, wherein a suction control is configured to modify the positive pressure gas flow. 6. The device of claim 1, wherein the body comprises an opening along at least a portion of the longitudinal channel that abuts the electrosurgical instrument when the body is coupled with the electrosurgical instrument so that a portion of the electrosurgical instrument covers the opening when the body is coupled with the electrosurgical instrument. 7. The device of claim 6, comprising a gasket configured to tightly couple the electrosurgical surgical instrument with the body so that the opening is tightly sealed when covered by the electrosurgical instrument. 8. The device of claim 7, wherein the body comprises a flexible membrane. 9. The device of claim 1, wherein the input port comprises one or more scalloped edges. 10. The device of claim 9, wherein the intake port is positioned on the input port. 11. The device of claim 1, wherein matter in the flow of matter comprises surgical smoke. 12. The device of claim 1, comprising one or more filters positioned to receive a flow of matter from the intake port. 13. The device of claim 1, comprising a suction control configured to open or close at least one of the intake port. 14. A device comprising: 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; andan emulsion segment positioned to receive the flow of matter. 15. The device of claim 1, wherein the input port is configured to couple with a suction nozzle. 16. The device of claim 1, wherein body is configured so that the electrosurgical instrument is operable when coupled with the body. 17. The device of claim 16, wherein the body is configured to be operable simultaneously with the electrosurgical instrument when coupled with the electrosurgical instrument.
