relates to a surgical instrument comprising an instrument handle (1) linked to a proximal end portion of a tube shaft (2) to the distal end portion of which an instrument head (4) is linked so as to be bendable, in which instrument head an effector (3) including at least one pivotal engaging element (30) is rotatably supported. The instrument handle (1) has a number of manipulators and/or operating mechanisms for operating the instrument head (4) and/or the effector (3) via gear trains. According to the invention, a clutch (37) which permits a zero point adjustment individual at least over a predetermined pivoting range of the instrument handle (1) is interposed in the gear train effecting the bending motion of the instrument head (4). The zero point is defined as a relative position of the instrument handle (1) with respect to the tube shaft (2) in which the instrument head (4) adopts a predetermined bending position with respect to the tube shaft (2).
