Smoke evacuating tissue guard for tissue removal and other surgical procedures

A smoke evacuating tissue guard, comprising:

• a tubular body having an outwardly flared proximal end portion and a distal end portion, the tubular body defining a longitudinally-extending passageway;
• a collar attached to the proximal end portion of the tubular body and defining an annular channel, the collar including:
• an outer annular section;
• an inner annular section facing the passageway and spaced from the proximal end portion of the tubular body to define a first gap therebetween;
• and
• a lip extending radially inward from the inner annular section and spaced from the proximal end portion of the tubular body to define a second gap therebetween;
• and
• an outlet extending from the collar and defining an inner channel in fluid communication with the annular channel, wherein the first gap is less than a diameter of the annular channel and the second gap, such that the smoke evacuation tissue guard is configured to establish a pressure differential in the first gap upon application of suction through the smoke evacuating tissue guard.
