A surgical device, comprising: a first jaw; a second jaw in opposed correspondence to the first jaw; a shaft pivotably coupled to at least one of the first or second jaws, the shaft defining a longitudinal axis therethrough that is perpendicular to a pivot axis; a first driver coupled to a first rotatable drive shaft, the first driver configured to move the first jaw relative to the second jaw; a second driver coupled to a second rotatable drive shaft, the second driver configured to drive a cutting and stapling element included in the second jaw; a first gear train having a first gear element arrangement, the first gear train configured to meshingly engage the first rotatable drive shaft; a second gear train having a second gear element arrangement, the second gear train configured to meshingly engage the second rotatable drive shaft; wherein the first and second gear trains enable rotation of the first and second jaws relative to the longitudinal axis defined by the shaft; a first bevel gear element and a second bevel gear element each rotatably mounted about a pin, at least one of the first or second gear elements having a central axis coaxial with the pivot axis around which the at least one of the first or second jaws pivots relative to the shaft, wherein the first and second bevel gear elements are actuatable by the first and second rotatable drive shafts, respectively, to position the first jaw relative to the second jaw; and a wedge member mechanically cooperating with a wedge driver, the wedge driver actuated by one of the first gear train or the second gear train, wherein a displacement of the first jaw relative to the second jaw and a displacement of the wedge member is a function of a rotation of the first and second rotatable drive shafts.
