Abstract
An end effector assembly of a forceps includes a first jaw member and a second jaw member. The first jaw member and the second jaw member are selectively positionable relative to one another. At least one of the jaw members includes an electrically conductive tissue engaging surface configured to connect to an electrosurgical energy source, and at least one of the jaw members includes two blade channels defined therein and extending therealong and a feed in member selectively positioned between the two blade channels. The end effector further includes a cutting blade that is translatable such that selective positioning of the feed in member enables the cutting blade to selectively enter into at least one of the two blade channels.
Claims20
An end effector assembly of a forceps comprising:
- a first jaw member;
- a second jaw member, the first jaw member and the second jaw member being selectively positionable relative to one another, at least one of the jaw members including an electrically conductive tissue engaging surface configured to connect to an electrosurgical energy source, at least one of the jaw members including two blade channels defined therein and extending therealong and a feed in member positioned between the two blade channels, the feed in member being selectively positionable;
- and
- a cutting blade that is translatable such that selective positioning of the feed in member enables the cutting blade to selectively enter into at least one of the two blade channels.
A forceps comprising:
- at least one shaft that includes an end effector assembly at a distal end thereof, the end effector assembly including:
- a first jaw member;
- a second jaw member, the first jaw member and the second jaw member being selectively positionable relative to one another, at least one of the jaw members including an electrically conductive tissue engaging surface configured to connect to an electrosurgical energy source, at least one of the jaw members including two blade channels defined therein and extending therealong and a feed in member positioned between the two blade channels, the feed in member being selectively positionable;
- and
- a cutting blade that is translatable such that selective positioning of the feed in member enables the cutting blade to selectively enter into at least one of the two blade channels.
A method of using forceps, the method comprising:
- opening a first jaw member and a second jaw member of the forceps, the first jaw member and the second jaw member being selectively positionable relative to one another, at least one of the jaw members including an electrically conductive tissue engaging surface configured to connect to an electrosurgical energy source, at least one of the jaw members including two blade channels defined therein and extending therealong and a feed in member positioned between the two blade channels;
- closing the first jaw member and the second jaw member to grasp tissue therebetween;
- selectively positioning the feed in member to enable a cutting blade to translate within at least one of the two blade channels;
- and
- moving the cutting blade through the at least one of the two blade channels to cut tissue grasped between the first jaw member and the second jaw member.
