Low impact cutting guard

A tissue guard for use with a surgical access device, comprising:

• a body including a proximal end, a distal end and a lumen defined therebetween;
• and
• a proximal lip extending radially from the proximal end and configured to mount atop a rim of an access device;
• a neck disposed at a junction between the lumen and the proximal lip and monolithically forming a narrowed channel extending along a circumference of the proximal end of the body;
• and
• an annular channel defined in the proximal lip and disposed in fluid communication with the lumen through the neck, the annular channel configured to direct surgical gases from the lumen, through the neck, and to a smoke evacuation system, the neck including geometry configured to induce the evacuation of surgical gases from the lumen to the annular channel of the proximal lip, wherein the proximal lip is an uninterrupted extension of the body to create an uninterrupted flow of surgical gases from the lumen through the neck and to the annular channel along an internal surface of the body to an internal surface of the proximal lip.
