A surgical device, comprising: a jaw portion (11 a) including a first jaw and a second jaw moveable relative to the first jaw, wherein the jaw portion includes a first longitudinal axis; a shaft portion (11 b) coupled to a proximal end of the jaw portion, wherein the shaft portion defines a second longitudinal axis; and a driver assembly configured to cause a portion of the jaw portion to rotate relative to the shaft portion (11 b) about the first longitudinal axis, the driver assembly further being configured to cause the jaw portion (11 a) to pivot relative to the shaft portion (11 b) about a pivot axis that is perpendicular to the second longitudinal axis, wherein the pivot axis is also perpendicular to the first longitudinal axis, wherein the first and second jaws (50,80) are moveable relative to each other in a plane, such that the pivot axis may be arranged parallel to the plane, characterised in that: the driver assembly is adapted to be driven by a first rotatable drive shaft and a second rotatable drive shaft, wherein the driver assembly is configured such that: (a) rotation of the first and second rotatable drive shafts in opposite directions relative to each other causes the jaw portion (11 a) to pivot relative to the shaft portion (11 b) about the pivot axis, and (b) rotation of the first and second rotatable drive shafts in a same direction relative to each other causes the said portion of the jaw portion (11 a) to rotate relative to the shaft portion (11 b) about the first longitudinal axis. a jaw portion (11 a) including a first jaw and a second jaw moveable relative to the first jaw, wherein the jaw portion includes a first longitudinal axis; a shaft portion (11 b) coupled to a proximal end of the jaw portion, wherein the shaft portion defines a second longitudinal axis; and a driver assembly configured to cause a portion of the jaw portion to rotate relative to the shaft portion (11 b) about the first longitudinal axis, the driver assembly further being configured to cause the jaw portion (11 a) to pivot relative to the shaft portion (11 b) about a pivot axis that is perpendicular to the second longitudinal axis, wherein the pivot axis is also perpendicular to the first longitudinal axis, wherein the first and second jaws (50,80) are moveable relative to each other in a plane, such that the pivot axis may be arranged parallel to the plane, characterised in that: the driver assembly is adapted to be driven by a first rotatable drive shaft and a second rotatable drive shaft, wherein the driver assembly is configured such that: (a) rotation of the first and second rotatable drive shafts in opposite directions relative to each other causes the jaw portion (11 a) to pivot relative to the shaft portion (11 b) about the pivot axis, and (b) rotation of the first and second rotatable drive shafts in a same direction relative to each other causes the said portion of the jaw portion (11 a) to rotate relative to the shaft portion (11 b) about the first longitudinal axis. the driver assembly is adapted to be driven by a first rotatable drive shaft and a second rotatable drive shaft, wherein the driver assembly is configured such that: (a) rotation of the first and second rotatable drive shafts in opposite directions relative to each other causes the jaw portion (11 a) to pivot relative to the shaft portion (11 b) about the pivot axis, and (b) rotation of the first and second rotatable drive shafts in a same direction relative to each other causes the said portion of the jaw portion (11 a) to rotate relative to the shaft portion (11 b) about the first longitudinal axis.
