Abstract
A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector. The surgical dissector can apply mechanical and/or electrosurgical energy to treated tissue.
Claims29
A surgical dissector, comprising:
- a first jaw member, comprising:
- a proximal end;
- a distal end;
- a first tissue contacting surface;
- a second tissue contacting surface;
- a metallic core, wherein said metallic core of said first jaw member is configured to transmit electrosurgical energy;
- and
- a nonmetallic layer disposed over at least a portion of said metallic core of said first jaw member, wherein said metallic core of said first jaw member is recessed relative to said nonmetallic layer of said first jaw member, and wherein said metallic core of said first jaw member is configured to contact tissue through a tissue-receiving recess defined in said nonmetallic layer of said first jaw member;
- a second jaw member, comprising:
- a proximal end;
- a distal end;
- a first tissue contacting surface;
- a second tissue contacting surface;
- a metallic core, wherein said metallic core of said second jaw member is configured to transmit electrosurgical energy;
- and
- a nonmetallic layer disposed over at least a portion of said metallic core of said second jaw member, wherein said metallic core of said second jaw member is recessed relative to said nonmetallic layer of said second jaw member, and wherein said metallic core of said second jaw member is configured to contact tissue through a tissue-receiving recess defined in said nonmetallic layer of said second jaw member;
- and
- a joint, wherein said first jaw member and said second jaw member are rotatable about said joint between closed and open positions, wherein said first jaw member and said second jaw member are configured to separate tissue by applying:
- a mechanical force to the tissue upon opening said first jaw member and said second jaw member from a said closed position to a said open position;
- and
- an electrosurgical force to the tissue.
18 more elements
A surgical instrument, comprising:
- a jaw, comprising:
- a metallic core;
- and
- an outer skin, wherein said outer skin comprises:
- an outer skin surface;
- a plurality of first through holes exposing said metallic core to an outer skin surface, wherein said plurality of first through holes comprise a first through hole size, and wherein said first through holes define a first recessed depth between said outer skin surface and a first tissue-contacting surface of said metallic core;
- and
- a plurality of second through holes exposing said metallic core to said outer skin surface, wherein said plurality of second through holes comprise a second through hole size, wherein said first through hole size is different than said second through hole size, and wherein said second through holes define a second recessed depth between said outer skin surface and a second tissue-contacting surface of said metallic core.
5 more elements
A surgical dissector, comprising:
- a first jaw member, comprising:
- a first tissue contacting surface, comprising:
- a first electrically conductive portion;
- and
- a first electrically insulative portion;
- a second jaw member, comprising:
- a second tissue contacting surface, comprising:
- a second electrically conductive portion;
- and
- a second electrically insulative portion;
- a pivot, wherein said first jaw member and said second jaw member are rotatable about said pivot;
- and
- means for separating tissue, comprising:
- means for applying a mechanical force to tissue of a patient through rotation of at least one of said first jaw member and said second jaw member into an open configuration from a closed configuration;
- and
- means for applying electrosurgical force to the tissue through at least one of said first electrically conductive portion and said second electrically conductive portion.
