Abstract

A smoke evacuation device that evacuates smoke from a surgical site and filters the smoke from the air. The smoke evacuation device can include a fluid trap for removing moisture from the smoke. The smoke evacuation device can also include a filter with a compression mechanism for compressing a filter medium. The smoke evacuation device can also include features for controlling flow parameters, noise, and vibrations of the device. A remote activation device can also be used to activate the smoke evacuation device upon detection of certain system parameters.

First claim

What is claimed is:

1. A smoke evacuation system, comprising:
a housing at least partially surrounding an enclosure;
an airflow path extending inside the enclosure from an inlet port to an outlet port of the smoke evacuation system; and
a cooling mechanism configured to induce airflow through the enclosure to cool the enclosure, the cooling mechanism comprising:
a first rotary element disposed within the airflow path, the first rotary element being configured to rotate when a pressurized gas flows through the airflow path; and
a second rotary element disposed outside the airflow path and within the housing, the second rotary element being linked to the first rotary element such that rotation of the first rotary element causes the second rotary element to rotate, rotation of the second rotary element circulates air throughout the enclosure.

2. The smoke evacuation system of claim 1 , further comprising a pump configured to pressurize a gas within the airflow path.

3. The smoke evacuation system of claim 2 , further comprising a motor configured to power the pump.

4. The smoke evacuation system of claim 3 , wherein the motor has a work output and wherein the induced airflow is proportional to the work output of the motor.

5. The smoke evacuation system of claim 1 , wherein the second rotary element is linked to the first rotary element by a rotary element coupler.

6. The smoke evacuation system of claim 5 , wherein the rotary element coupler comprises one or more ball bearings and wherein the rotary element coupler is disposed in-line with the airflow path so as to prevent leaking at the rotary element coupler.

7. A smoke evacuation system, comprising:
a housing at least partially surrounding an enclosure;
an airflow path extending inside the enclosure from an inlet port to an outlet port of the smoke evacuation system; and
a cooling mechanism configured to induce airflow through the enclosure to cool the enclosure, the cooling mechanism comprising:
a first rotary element disposed within the airflow path, the first rotary element being configured to rotate when a pressurized gas flows through the airflow path; and
a second rotary element disposed outside the airflow path and within the housing, rotation of the second rotary element being configured to circulate air throughout the enclosure.

8. The smoke evacuation system of claim 7 , further comprising a pump configured to pressurize a gas within the airflow path.

9. The smoke evacuation system of claim 8 , further comprising a motor configured to power the pump.

10. The smoke evacuation system of claim 9 , wherein the motor has a work output and wherein the induced airflow is proportional to the work output of the motor.

11. The smoke evacuation system of claim 7 , wherein the first rotary element and the second rotary element are linked together such that rotation of the first rotary element causes the second rotary element to rotate.

12. The smoke evacuation system of claim 11 , wherein the first and second the second rotary elements are linked together by a rotary element coupler.

13. The smoke evacuation system of claim 12 , wherein the rotary element coupler comprises one or more ball bearings and wherein the rotary element coupler is disposed in-line with the airflow path so as to prevent leaking at the rotary element coupler.

14. A smoke evacuation system, comprising:
a housing at least partially surrounding an enclosure;
an airflow path extending inside the enclosure from an inlet port to an outlet port of the smoke evacuation system, the airflow path comprising a filter, a pump, and an exhaust mechanism; and
a cooling mechanism configured to induce airflow through the enclosure to cool the enclosure, the cooling mechanism comprising:
a first rotary element disposed within the airflow path, the first rotary element being configured to rotate when a pressurized gas flows through the airflow path; and
a second rotary element linked to the first rotary element, the second rotary element being disposed outside the airflow path and within the housing, rotation of the second rotary element being configured to circulate air throughout the enclosure.

15. The smoke evacuation system of claim 14 , further comprising a motor configured to power the pump.

16. The smoke evacuation system of claim 14 , wherein the first rotary element and the second rotary element are linked together such that rotation of the first rotary element causes the second rotary element to rotate.

17. The smoke evacuation system of claim 16 , wherein the first and second the second rotary elements are linked together by a rotary element coupler.

18. The smoke evacuation system of claim 17 , wherein the rotary element coupler comprises one or more ball bearings and wherein the rotary element coupler is disposed in-line with the airflow path so as to prevent leaking at the rotary element coupler.

19. The smoke evacuation system of claim 14 , wherein the exhaust mechanism comprises a cover over the outlet port, the covering being mounted on one or more resilient members.

20. The smoke evacuation system of claim 14 , wherein the exhaust mechanism comprises a diffuser having a plurality of vanes that are spaced apart and angled such that the diffuser is configured to disperse the airflow in a variety of directions as the airflow exits the smoke evacuation system.
