1. A device for moving tissue inside the body, in particular bone tissue, said device including: a reference part; a transport part which is slidably mounted relative to the reference part; a threaded rod comprising at least one thread, the threaded rod being pivotably mounted relative to the reference part; a control shaft; driving means connecting the control shaft to the threaded rod; a connecting nut linking the transport part and the threaded rod, the connecting nut being mounted onto the threaded rod and being rotatably guided relative to the reference part; and means for converting the movement of the connecting nut along the threaded rod into a movement of the transport part relative to the reference part; wherein in order to limit longitudinal translation of the threaded rod relative to the reference part, a first abutment and a second abutment rigidly connected to the threaded rod respectively cooperate with a first bearing and a second bearing, these bearings being rigidly connected to the reference part and being placed at a distance from one another between the first abutment and the second abutment, the connecting nut being movable along the threaded rod between the first bearing and second bearing.
