    • Surgical instrument comprising a handle with a main body having a central axis (C), a lever pivotable around a pivot axis (H) that is fixed with respect to the main body, wherein the lever is provided with a finger abutment section comprising a lower finger rest adapted for at least partially contacting the ventral sides of both a first and second finger of a user during pivoting movement of said finger abutment section towards the central axis, and an upper finger rest adapted for at least partially contacting the dorsal sides of both said fingers during pivoting movement of the finger abutment section away from the central axis; and a septum fixed to the lower and upper finger rest and extending therebetween to form a separate first and second finger receiving portion for respectively receiving a first and a second finger of the user; wherein the lever is arranged for pivoting around the pivot axis (H) in such a manner that during pivoting of the lever, a central plane (S) of the septum remains substantially coplanar with a plane parallel to the central axis. The handle (10) is further provided with a unitary user operable control (30) that is rotatable and bendable to cause rotation of the tubular body (40) and bending of the distal tool (50).
