An electrosurgical forceps, comprising: first and second shaft members each defining a proximal end and a distal end; first and second jaw members engaged with the respective first and second shaft members and coupled to each other such that moving the first and second shaft members relative to each other from an open position to a closed position moves the first and second jaw members relative to each other from a spaced-apart position to an approximated position; a knife assembly operably coupled to one of the first shaft member or the second shaft member and including a knife blade disposed within one of the first jaw member or the second jaw member, the first and second shaft members movable from the closed position to a cutting position to move the knife blade from a retracted position to an extended position, wherein the knife blade extends at least partially between the first and second jaw members; an activation button disposed on the first shaft member, the activation button configured for selective activation to supply energy to the first and second jaw members; characterised by an activation assembly disposed within the second shaft member and positioned to oppose the activation button, the activation assembly including a foot movably disposed within a cavity defined within the second shaft member, wherein moving the first and second shaft members relative to each other from the open position to the closed position urges the foot into contact with the activation button to supply energy to the first and second jaw members, and wherein moving the first and second shaft members relative to each other from the closed position to the cutting position urges the activation button into contact with the foot such that the foot is recessed into the cavity and at least a portion of the activation button is accommodated within the cavity. first and second shaft members each defining a proximal end and a distal end; first and second jaw members engaged with the respective first and second shaft members and coupled to each other such that moving the first and second shaft members relative to each other from an open position to a closed position moves the first and second jaw members relative to each other from a spaced-apart position to an approximated position; a knife assembly operably coupled to one of the first shaft member or the second shaft member and including a knife blade disposed within one of the first jaw member or the second jaw member, the first and second shaft members movable from the closed position to a cutting position to move the knife blade from a retracted position to an extended position, wherein the knife blade extends at least partially between the first and second jaw members; an activation button disposed on the first shaft member, the activation button configured for selective activation to supply energy to the first and second jaw members; characterised by an activation assembly disposed within the second shaft member and positioned to oppose the activation button, the activation assembly including a foot movably disposed within a cavity defined within the second shaft member, wherein moving the first and second shaft members relative to each other from the open position to the closed position urges the foot into contact with the activation button to supply energy to the first and second jaw members, and wherein moving the first and second shaft members relative to each other from the closed position to the cutting position urges the activation button into contact with the foot such that the foot is recessed into the cavity and at least a portion of the activation button is accommodated within the cavity.
