In a surgical instrument comprising a tool which is oscillatingly pivotable about an axis of rotation and a rotatingly driven drive shaft which by means of an eccentric causes an oscillating lever which is rotationally fixedly connected to the tool to pivot oscillatingly back and forth, in order to achieve a simplified adaptation of the pivoting angle to the respective tool, it is proposed that the drive shaft comprise adjacent to each other at least two eccentrics with different eccentricity, that an oscillating lever pivotable about the axis of rotation of the tool be associated with each eccentric, and that the tool be rotationally fixedly connected to only one of the oscillating levers. |
