A forceps includes an end effector assembly including first and second jaw members, a blade, a lever member operably coupled to the end effector, a trigger member operably coupled to the blade and defining an actuation path therealong. A trigger safety member is pivotably coupled to the lever member such that, when the lever member is disposed in an initial position, the trigger safety member is disposed in a position blocking the trigger member. When the lever member is disposed in a compressed position, the trigger safety member is disposed in a position, wherein the trigger safety member is displaced from the actuation path to permit movement of the trigger member, wherein the safety member rotates relative to the lever member as a function of movement of the lever member to block/unblock the trigger member.
1. A forceps, comprising: an end effector assembly including first and second jaw members, at least one of the jaw members movable relative to the other between an open position and a closed position for grasping tissue therebetween;a blade movable between a retracted position wherein the blade is p
1. A forceps, comprising: an end effector assembly including first and second jaw members, at least one of the jaw members movable relative to the other between an open position and a closed position for grasping tissue therebetween;a blade movable between a retracted position wherein the blade is proximal to the jaw members and a deployed position wherein the blade extends at least partially between the jaw members to cut tissue grasped therebetween;a lever member movable between an initial position and a compressed position;a drive assembly operably coupled to the at least one jaw member, the drive assembly selectively translatable between first and second positions for moving the at least one jaw member between the open and closed positions;at least one driving member operably coupled to the drive assembly at a first end and to the lever member at a second end such that movement of the lever member between the initial and compressed positions translates the drive assembly between the first and second positions to move the at least one jaw members between the open and closed positions;a trigger member operably coupled to the blade and positionable to move the blade between the retracted position and the deployed position, the trigger member defining an actuation path therealong; anda trigger safety member directly pivotably coupled to the lever member about a first pivot and directly pivotably coupled to the driving member about a second pivot such that, when the lever member is disposed in the initial position, the trigger safety member is disposed in a position blocking actuation of the trigger member and when the lever member is disposed in the compressed position, the trigger safety member is disposed in a position wherein the trigger safety member is displaced from the actuation path to permit movement of the trigger member, wherein the trigger safety member rotates relative to the lever member about the first pivot as a function of movement of the lever member to block/unblock the trigger member. 2. The forceps of claim 1, further comprising a housing enclosing at least a portion of the lever member, the trigger member, and the trigger safety member. 3. The forceps of claim 2, wherein the lever member and the trigger member are operably coupled to the housing at different pivots. 4. The forceps of claim 2, wherein the lever member and the trigger member are operably coupled to the housing at a single pivot. 5. The forceps of claim 1, further comprising at least one blade deployment member operably coupled to the blade at an engagement pin and pivotably coupled to the trigger member. 6. The forceps of claim 1, wherein the lever member is operably coupled to the trigger safety member about a trigger pivot. 7. The forceps of claim 1, further comprising a latch mechanism configured to releasably secure the lever member in the compressed position. 8. The forceps of claim 1, wherein the trigger safety member is further configured to kickback and forcibly return the trigger member to an un-actuated position. 9. The forceps of claim 1, further comprising a spring to bias the trigger member towards an un-actuated position. 10. The forceps according to claim 1, wherein the trigger safety member includes an intermediate portion, a distal portion extending distally from the intermediate portion, and a proximal portion extending proximally from the intermediate portion, and wherein the first pivot pivotably couples the intermediate portion of the trigger safety member to the lever member. 11. The forceps according to claim 10, wherein the distal portion of the trigger safety member is positioned to block actuation of the trigger member when the lever member is disposed in the initial position and is displaced from the actuation path to permit movement of the trigger member when the lever member is disposed in the compressed position. 12. The forceps according to claim 10, wherein the second pivot pivotably couples the proximal portion of the trigger safety member to the driving member. 13. A forceps, comprising: a housing;an end effector assembly including first and second jaw members, at least one of the jaw members movable relative to the other between an open position and a closed position for grasping tissue there between;a blade movable between a retracted position wherein the blade is proximal to the jaw members and a deployed position wherein the blade extends at least partially between the jaw members to cut tissue grasped therebetween;a lever member coupled to the housing and movable between an initial position and a compressed position;a trigger member operably coupled to the housing and coupled to the blade via a blade deployment member, wherein the blade deployment member is operably coupled to the blade at an engagement pin, wherein the trigger member is positionable to move the blade between the retracted position and the deployed position, the trigger member defining an actuation path therealong;a drive assembly operably coupled to the at least one member, the drive assembly selectively translatable between first and second positions for moving the at least one jaw member between the open and closed positions;at least one driving member operably coupled to the drive assembly at a first end and to the lever member at a second end such that movement of the lever member between the initial and compressed positions translates the drive assembly between the first and second positions to move the at least one jaw member between the open and closed positions; anda trigger safety member directly pivotably coupled to the lever member about a first pivot and directly pivotably coupled to the driving member about a second pivot such that, when the lever member is disposed in the initial position, the trigger safety member is disposed in a position blocking actuation of the trigger member, and when the lever member is disposed in the compressed position, the trigger safety member is disposed in a position wherein the trigger safety member is displaced from the actuation path to permit movement of the trigger member, wherein the trigger safety member rotates relative to the lever member about a first pivot and the driving member about the second pivot as a function of movement of the lever member to block/unblock the trigger member. 14. The forceps of claim 13, further comprising a latch mechanism configured to releasably secure the lever member in the compressed position. 15. The forceps of claim 13, wherein said trigger safety member is further configured to kickback and forcibly return the trigger member to an un-actuated position. 16. The forceps of claim 13, further comprising a spring to bias the trigger member towards an un-actuated position. 17. The forceps according to claim 13, wherein the trigger safety member includes an intermediate portion, a distal portion extending distally from the intermediate portion, and a proximal portion extending proximally from the intermediate portion, and wherein the first pivot pivotably couples the intermediate portion of the trigger safety member to the lever member. 18. The forceps according to claim 17, wherein the distal portion of the trigger safety member is positioned to block actuation of the trigger member when the lever member is disposed in the initial position and is displaced from the actuation path to permit movement of the trigger member when the lever member is disposed in the compressed position. 19. The forceps according to claim 17, wherein the second pivot pivotably couples the proximal portion of the trigger safety member to the driving member.
