US 12,108,949 B2 · Cutting guard with ground connection

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.
