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, an open distal end, and a lumen extending through the body between the open proximal end and the open distal end;
- and
- a lip extending radially outwardly from the open proximal end of the body, the lip including a finger extending from an exterior peripheral surface thereof, the finger including 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.
A surgical system, comprising:
- an access device including a proximal end portion, a distal end portion, and a body extending between the proximal and distal end portions, the body 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, an open distal end, and a lumen extending through the body between the open proximal end and the open distal end;
- and
- a lip extending radially outwardly from the open proximal end of the body, the lip including a finger extending from an exterior peripheral surface thereof, the finger including a flange at a distal end thereof adapted to operably engage an underside of the proximal ring of the access device to secure the tissue guard therein.
A tissue guard, comprising:
- 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;
- and
- a lip extending radially outwardly from the open proximal end of the body, the lip including at least one finger extending from an exterior peripheral surface thereof, the at least one finger including a flange at a distal end thereof, the at least one finger adapted to mount atop a proximal ring of an access device such that the flange operably engages an underside of the proximal ring to secure the tissue guard therein.
A tissue guard, comprising:
- a body including a first section and a second section each defining an open proximal end, an open distal end, and a lumen extending therethrough, the distal end of the first section including a plurality of grooves defined therein and the proximal end of the second section including a corresponding plurality of threads disposed thereon configured to operably engage the grooves to form the body, wherein relative rotation of the first section relative to the second section adjusts the height of the body when disposed within an access device.
