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 method comprising: providing a device to a user, wherein the device is configured to couple with an electrosurgical instrument and comprises a first port for liquid intake and a second port for smoke intake, wherein the second port is positioned proximally to the first port along the device so that when liquid flows from the first port through a narrowing in the device, a Venturi effect is generated that enhances smoke intake at the second port, wherein the second port is positioned along the device so that it opens into the narrowing. 2. The method of claim 1, wherein the flow of matter is passed through narrowing in the device using a suction source that is coupled with the device. 3. The method of claim 1, comprising one or more filters positioned to receive a flow of matter from the one or more intake ports. 4. The method of claim 2, wherein the device comprises a central horizontal axis and the narrowing comprises one or more surfaces positioned at an angle of 15 degrees relative to the central horizontal axis. 5. The method of claim 1, wherein the narrowing is adjustable. 6. The method of claim 4, wherein the angle is adjustable. 7. The method of claim 1, wherein the device is further configured to generate a Coanda effect by passage of a pressurized gas through the device so that an area of low pressure is generated within the device. 8. The method of claim 7, wherein a suction control is configured to modify the pressurized gas flow. 9. The method of claim 1, wherein the device comprises a gasket configured to tightly couple the electrosurgical instrument with the device so that the opening is tightly sealed when covered by the electrosurgical instrument. 10. The method of claim 1, wherein the first port is configured to couple with a suction nozzle. 11. The method of claim 1, wherein the first port comprises one or more scalloped edges. 12. The method of claim 1, wherein the device comprises a suction control configured to open or close at least one of the second port. 13. A method comprising: providing a device to a user, wherein the device is configured to couple with an electrosurgical instrument, the device is configured to generate one or more of a Venturi effect and a Coanda effect, and wherein the device comprises an emulsion segment positioned to receive the flow of matter. 14. The method of claim 1, wherein device is configured so that the electrosurgical instrument is operable when coupled with the device. 15. The method of claim 14, wherein the device is configured to be operable simultaneously with the electrosurgical instrument when coupled with the electrosurgical instrument. 16. A method comprising: coupling a suction device to an electrosurgical instrument so that a first port of the suction device configured for liquid suction is positioned towards a distal end of the electrosurgical instrument and a second port of the suction device configured for smoke suction is positioned proximally to the first port;generating a liquid flow through the first port and through a narrow portion of the suction device; andgenerating a Venuri effect that enhances a flow of smoke through the second port as a result of the liquid flow through the narrow portion of the suction device, wherein the second port is positioned along the device so that it opens into the narrow portion. 17. The method of claim 16, comprising one or more filters positioned to receive a flow of matter from the one or more intake ports. 18. The method of claim 16, wherein the suction device comprises a central horizontal axis and the narrow portion comprises one or more surfaces positioned at an angle of 15 degrees relative to the central horizontal axis. 19. The method of claim 16, wherein a diameter of the narrow portion is adjustable.
