Abstract
A tissue guard includes a body defining an open proximal end, an open distal end, and a lumen extending through the body between the open proximal end and the open distal end. A lip extends radially outwardly from the open proximal end of the body, the lip including a finger extending from an exterior peripheral surface thereof. The finger includes a flange at a distal end thereof adapted to operably engage an underside of a proximal ring of an access device to secure the tissue guard therein.
Claims20
A tissue guard, comprising:
- a body defining an open proximal end portion, an open distal end portion, and a lumen extending through the body between the open proximal end portion and the open distal end portion;
- and
- a lip including a proximal end extending radially outwardly from the open proximal end portion of the body and a distal end extending inwardly towards the lumen to form an annular channel having an annular opening into the lumen, the annular channel configured to direct surgical exhaust and surgical fluids from an operating cavity to a port defined in the lip;
- a finger extending from an exterior peripheral surface of the lip;
- and
- a flange disposed at a distal end portion of the finger, the flange tapering inwardly towards the lumen of the body from the finger to an inner edge of the flange to facilitate insertion and engagement of the tissue guard with an access device, the flange adapted to operably engage an underside of a proximal end portion of the access device to secure the tissue guard within the access device.

A surgical system, comprising:
- an access device including a proximal end portion, a distal end portion, and a body portion extending between the proximal and distal end portions, the body portion defining a passageway extending therethrough, wherein the proximal end portion defines a ring extending radially-inwardly into the passageway;
- and
- a tissue guard, including:
- a body defining an open proximal end portion, an open distal end portion, and a lumen extending through the body between the open proximal end portion and the open distal end portion;
- a lip including a proximal end extending radially outwardly from the open proximal end portion of the body and a distal end extending inwardly towards the lumen to form an annular channel having an annular opening into the lumen, the annular channel configured to direct surgical exhaust and surgical fluids from an operating cavity to a port defined in the lip;
- a finger extending from an exterior peripheral surface of the lip;
- and
- a flange disposed at a distal end portion of the finger, the flange tapering inwardly towards the lumen of the body from the finger to an inner edge of the flange to facilitate insertion and engagement of the tissue guard with the access device, the flange adapted to operably engage the ring of the access device to secure the tissue guard within the access device.

A tissue guard, comprising:
- a body defining an open proximal end portion, an open distal end portion, and a lumen extending through the body between the open proximal end portion and the open distal end portion;
- a lip extending radially outwardly from the open proximal end portion of the body and including a distal end extending inwardly towards the lumen to form an annular channel within the lip, the annular channel being in direct open communication with the lumen of the body and configured to direct surgical exhaust from an operating cavity to a port defined in the lip;
- at least one finger extending from an exterior peripheral surface of the lip;
- and
- a flange disposed at a distal end portion of the at least one finger, the flange diminishing in thickness along a length of the flange extending from the at least one finger to an inner edge of the flange, the at least one finger adapted to mount atop a proximal end portion of an access device such that the flange operably engages an underside of the proximal end portion of the access device to secure the tissue guard within the access device.
