Surgical procedures often incorporate the use of various energy-driven cautery and tissue dissection instruments which thermally ablate human tissue. A significant drawback of these systems is the generation of a surgical smoke plume. This smoke contains hazardous compounds including particulates, volatile organic compounds, toxic gases, and pathogenic microorganisms. This smoke plume contaminates the operating room air, which is detrimental to the occupational health of the surgical staff and patient.
The prior art describes multiple systems for the evacuation of a surgical smoke plume. However, these systems have significant human factor drawbacks. In prior art evacuation systems, a sterilized suction instrument needs to be placed directly into the surgical field. These devices include cautery pencils with integral vacuum lumens, suction handpieces, or surgical tubing. In each case, the suction device alters the visual and/or tactile access to the surgical site. This alteration can be detrimental to the surgeon, resulting in reduced visualization, access, and tactile feedback from the surgical site.
What is needed, therefore, is a surgical smoke evacuation device which is proximate to but does not intrude upon the surgical site.
In the current invention, a sterile self-supporting conformable tube is placed in proximity to the surgical site but positioned outside of the surgeon's line of sight. In order to safely and effectively accomplish this, several innovations are required. These include sterilization means for the self-supporting tube, means to isolate the tube and associated filter from a vacuum system, integration of a filtration means, and a means to incorporate different tube shapes for different anatomical needs/positions. These and further innovations shall be elucidated in the claims and drawings below.
