A surgical device, comprising: a handle housing having an elongate shaft extending distally therefrom; an end effector at the distal end of the elongate shaft; a drive assembly configured to actuate the end effector; a trigger coupled to the handle housing and pivotable about a trigger pivot axis (T a) from an unactuated position to an actuated position; a pivot linkage having a first end coupled to the drive assembly and a second end, the pivot linkage being pivotable about the trigger pivot axis (T a); and an overload member comprising an overload linkage and a biasing element, the overload member coupled at least between the second end of the pivot linkage and the trigger; wherein the overload linkage has first and second ends (258a, 258b), the first end of the overload linkage coupled to the second end of the pivot linkage at an engagement point, and the second end of the overload linkage slidably coupled to the trigger via a movable pin and operably coupled to the biasing element, wherein pivotal movement of the trigger about the trigger pivot axis (T a) from the unactuated position to the actuated position is configured to transfer a closing force through the overload member to the second end of the pivot linkage thereby causing the pivot linkage to pivot about the trigger pivot axis (T a) such that the first end of the pivot linkage distally advances the drive assembly to cause actuation of the end effector, and wherein, when the closing force exceeds a predetermined threshold force, pivotal movement of the trigger about the trigger pivot axis (T a) from the unactuated position to the actuated position is configured to transfer the closing force to the overload member to cause the overload member to move in a manner that prevents transfer of the closing force to the pivot linkage such that the pivot linkage remains stationary relative to the handle housing, wherein the biasing element is configured to bias the overload linkage to a first position when the trigger pivots about the trigger pivot axis (T a) from the unactuated position to the actuated position until the closing force exceeds the predetermined threshold force. a handle housing having an elongate shaft extending distally therefrom; an end effector at the distal end of the elongate shaft; a drive assembly configured to actuate the end effector; a trigger coupled to the handle housing and pivotable about a trigger pivot axis (T a) from an unactuated position to an actuated position; a pivot linkage having a first end coupled to the drive assembly and a second end, the pivot linkage being pivotable about the trigger pivot axis (T a); and an overload member comprising an overload linkage and a biasing element, the overload member coupled at least between the second end of the pivot linkage and the trigger; wherein the overload linkage has first and second ends (258a, 258b), the first end of the overload linkage coupled to the second end of the pivot linkage at an engagement point, and the second end of the overload linkage slidably coupled to the trigger via a movable pin and operably coupled to the biasing element, wherein pivotal movement of the trigger about the trigger pivot axis (T a) from the unactuated position to the actuated position is configured to transfer a closing force through the overload member to the second end of the pivot linkage thereby causing the pivot linkage to pivot about the trigger pivot axis (T a) such that the first end of the pivot linkage distally advances the drive assembly to cause actuation of the end effector, and wherein, when the closing force exceeds a predetermined threshold force, pivotal movement of the trigger about the trigger pivot axis (T a) from the unactuated position to the actuated position is configured to transfer the closing force to the overload member to cause the overload member to move in a manner that prevents transfer of the closing force to the pivot linkage such that the pivot linkage remains stationary relative to the handle housing, wherein the biasing element is configured to bias the overload linkage to a first position when the trigger pivots about the trigger pivot axis (T a) from the unactuated position to the actuated position until the closing force exceeds the predetermined threshold force.
