Abstract
A tissue guard for use with a surgical access device includes a proximal ring having proximal and distal ends, the distal end configured to operably couple to a ground ring that ultimately electrically connects to an electrical ground. One or more mechanical interfaces extend about the proximal ring and are configured to mechanically engage a rim of an access device to secure the tissue guard thereon. A retention body is configured to operably couple to a distal end of the ground ring, the retention body including a distal end configured to operably engage the access device to secure the tissue guard therein.

1-15. (canceled)
A tissue guard configured for positioning within an opening in tissue, comprising:
- a body configured for positioning within an opening in tissue, the body defining an open proximal end portion, an open distal end portion, and a lumen extending therethrough between the open proximal and distal end portions, the body including an inner peripheral surface surrounding the lumen;
- an electrically conductive ground ring disposed on the inner peripheral surface of the body between the proximal and distal end portions thereof;
- and
- a ground wire electrically coupled to the electrically conductive ground ring and configured for ultimate connection to an electrical ground.
A tissue guard configured for positioning within an opening in tissue, comprising:
- an outer shell configured for positioning within an opening in tissue, a portion of the outer shell including a conductive material disposed on an inner peripheral surface thereof;
- an inner shell disposed within the outer shell, the inner shell defining a lumen configured to provide access to an internal surgical site and including an inner peripheral surface surrounding the lumen, the inner shell including a plurality of connectors disposed on an outer peripheral surface thereof, the plurality of connectors configured to electrically connect to the conductive material;
- and
- a ground wire electrically connected to the plurality of connectors and configured to ultimately connect to an electrical ground.
A tissue guard configured for positioning within an opening in tissue, comprising:
- a body configured for positioning within an opening in tissue, the body defining an open proximal end portion, an open distal end portion, and a lumen extending therethrough between the open proximal and distal end portions, the body including an inner peripheral surface surrounding the lumen;
- and
- a ground clip including a proximal mechanical interface configured to engage the proximal end portion of the body to attach the ground clip thereto and an electrically conductive section configure to extend distally at least partially along the inner peripheral surface of the body, the electrically conductive section configured for ultimate connection to an electrical ground.
