The invention relates to a device for simulating a rod-shaped virtual surgical instrument, in particular for simulating an endoscopic instrument comprising a handle. Said device is provided with a virtual trocar and is equipped with force feedback apparatus. The force feedback apparatus has two connecting pieces, one connecting piece being connected to one half of the handle and the other connecting piece being connected to the other half of the handle. The two connecting pieces are interconnected in a detachable engagement in such a way, that said two connecting pieces can be displaced freely in relation to one another in a first control position and in a second control position and can only be displaced in relation to one another by means of the spring by applying a force to the handle.
