Bipolar electrosurgical hand shears

An apparatus for treating tissue, comprising:

• (a) a first jaw having:
• (i) a first grasping surface, and
• (ii) a first exterior surface arranged opposite of the first grasping surface;
• (b) a second jaw having:
• (i) a second grasping surface, and
• (ii) a second exterior surface arranged opposite of the second grasping surface,
• wherein the first and second grasping surfaces are configured to grasp tissue positioned therebetween when the first and second jaws are in a closed position;
• and
• (c) a tissue engagement feature disposed on the first exterior surface and protruding outwardly away from the first grasping surface and a longitudinal axis of the first jaw, wherein the tissue engagement feature is configured to engage tissue and thereby restrict movement of the first jaw relative to the tissue when the first and second jaws are in an open position.

An apparatus for treating tissue, comprising:

• (a) a first jaw having:
• (i) a first grasping surface, and
• (ii) a first exterior surface arranged opposite of the first grasping surface;
• (b) a second jaw pivotable relative to the first jaw, wherein the second jaw has:
• (i) a second grasping surface, and
• (ii) a second exterior surface arranged opposite of the second grasping surface,
• wherein the first and second grasping surfaces are configured to grasp tissue positioned therebetween when the first and second jaws are in a closed position;
• (c) a first tissue engagement feature disposed on the first exterior surface;
• and
• (d) a second tissue engagement feature disposed on the second exterior surface,
• wherein the first and second tissue engagement features are configured to engage tissue and thereby restrict movement of the first and second jaws relative to the tissue when the first and second jaws are in an open position.
