Surgical instrument with a handle

A surgical instrument comprising:

• a handle;
• a shaft extending from the handle into a distal direction along a longitudinal axis;
• and
• a medical forceps or scissor at a distal end of the shaft,
• wherein the handle comprises a plurality of manual actuating members configured to manipulate the medical forceps or scissor for rotating, tilting and open-closing movements, and the plurality of manual actuating members comprises:
• a first actuating member being rotatable around a first rotational axis that is collinear or parallel with the longitudinal axis of the shaft,
• a second actuating member being rotatable around a second rotational axis that collinear or parallel with the longitudinal axis of the shaft, the second actuating member being movable along the longitudinal axis of the shaft,
• wherein a rotation of the second actuating member relative to the handle rotates a distal end section of the shaft with the medical forceps or scissor around the longitudinal axis, and
• wherein an axial movement of the second actuating member causes the open-closing movements of jaw parts of the medical forceps or scissor.
