Abstract: A tissue guard for use with a surgical access device includes an upper portion having: a proximal ring with proximal and distal ends, the distal end having a first mechanical interface disposed therearound; a plurality of fingers extending about the proximal ring that the access device; an inner peripheral surface having an upper channel; and a plurality of second mechanical interfaces disposed about a distal end of the inner peripheral surface. The lower portion includes: a body having a proximal end including a corresponding first mechanical interface disposed therearound configured to engage the first mechanical interface of the upper portion; a lower channel defined within the body including a plurality of corresponding second mechanical interfaces configured to engage the plurality of second mechanical interfaces of the upper portion; and long and short petals disposed of the lower portion to facilitate insertion of the tissue guard within an incision.

Abstract: Access assemblies include an instrument valve housing and a valve assembly disposed within the cavity of the instrument valve housing. The valve assembly includes a guard assembly, and a seal assembly disposed distal of the guard assembly. The seal assembly includes a support member including a ring portion and a seal portion disposed within the ring portion. The seal assembly further includes a plurality of seal sections extending from the ring portion of the support member. The support member and the plurality of seal sections are integrally formed.

Abstract: A tissue specimen retrieval bag assembly includes a tissue specimen bag having an open proximal end and a closed distal end, the proximal end including a cuff defined therein and extending therearound. A flexible bag brim is disposed within the cuff and is transitionable between a first, collapsed configuration and a second, expanded configuration. The flexible bag brim includes a cross section configured to facilitate both furling the tissue specimen bag onto itself around the bag brim when the bag brim is disposed in the second, expanded configuration and securing the tissue specimen bag in a desired furled configuration.
