A surgical instrument for cutting and grasping tissue comprising a handle assembly, an elongated member and first and second jaws. A first movable member moves the second jaw in a first direction about a first pivot axis in a grasping action and a second movable member moves the second jaw in a second direction different than the first direction and about a second pivot axis in a cutting action. A switch is positioned at the proximal portion of the instrument and a selecting member is actuated by movement of the switch, the selecting member movable between a first position to enable movement of the second jaw in the first direction and prohibit movement in the second direction and a second position to enable movement of the second jaw in the second direction and prohibit movement in the first direction.
1. A surgical instrument for performing first and second different functions on tissue comprising: an elongated member;a first jaw positioned adjacent a distal portion of the elongated member;a second jaw positioned adjacent the distal portion of the elongated member and mounted for movement with re
1. A surgical instrument for performing first and second different functions on tissue comprising: an elongated member;a first jaw positioned adjacent a distal portion of the elongated member;a second jaw positioned adjacent the distal portion of the elongated member and mounted for movement with respect to the first jaw, the first and second jaws relatively movable between open and closed positions in a first orientation and further movable between open and closed positions in a second different orientation;a first actuating mechanism for moving the jaws in the first orientation;a first handle for moving the first actuating mechanism;a second actuating mechanism for moving the jaws in the second orientation;a second handle for moving the second actuating mechanism; anda switch for choosing the first or second actuating mechanism, wherein the switch can be activated only when the jaws are in the closed position, and the switch preventing movement of one of the first and second handles while enabling movement of the other of the first and second handles. 2. The instrument of claim 1, wherein the first jaw has a first upper surface with a first edge and a second edge and the second jaw has a second lower surface with a third edge and a fourth edge, wherein when the jaws move between open and closed positions in the first orientation to perform a cutting function, the first and third edges pass each other in substantially parallel planes and when the jaws move between open and closed positions in the second orientation in a grasping function, the first and third edges pivot away from each other in transverse planes. 3. The instrument of claim 1, wherein movement of the switch moves a link in a clockwise or counterclockwise direction to effect operative engagement of one of the actuating mechanisms to prevent movement thereof. 4. The instrument of claim 1, further comprising a safety member operably associated with the switch, the safety member movable between a first position to lock the switch against movement and a second position to allow movement of the switch, the safety automatically locking the switch when the jaws are in the open position. 5. The instrument of claim 4, wherein the safety member engages an aperture in the switch.
