摘要

A surgical instrument for dissection of bones or other tissue (b), wherein the surgical instrument (10) comprises: a motor (20) with a power output, a sezierwerkzeug (50) with a tool shaft (52), comprising a sezierkopf (54) at the distal end and a tool shaft clutch (56) at the opposite proximal end, a first switching network (30), which for the selective coupling of the power from gear with the tool shaft clutch (56) of the dissecting (50) is used in an operating position, wherein the switching network (30) comprises an unlocking position, in which the sezierwerkzeug (50) of the power output can be decoupled, wherein the first switching network (30) further comprises a distal direction of rotation of the actuating part (36) for controlling the movement of the first switching network (30) of the operating position into the unlocking position, the upper portion of casing tube (40), the at least a partial region of the tool shaft (52) is positioned, in order to at least this partial area of the tool shaft (52) in front of the sezierkopf (54) to support, wherein the upper portion of casing tube (40) is displaceable, in order to the position with the distal direction of rotation of the actuating part (36) between..
