Medical mechatronic male and female interface device

An interface device configured to couple a surgical assistance system to a mount, the interface device comprising:

• a medical mechatronic male interface device comprising:
• a base comprising an end face and a functional body extending from the end face;
• a first mechanical coupling for positive and/or non-positive coupling to a medical mechatronic female interface device;
• and
• at least one first electronic interface configured to connect to a second electronic interface of the female interface device,
• wherein the functional body comprises a centring device configured to center the surgical assistance system free of play relative to the base, and
• wherein the centring device comprises a first functional surface, a second functional surface, and a third functional surface that are non-parallel to each other and that have normals which do not lie in a common plane;
• and
• a medical female interface device configured to be coupled to the male interface device, the female interface device comprising:
• a frame defining a central recess for receiving the functional body of the male interface device;
• and
• a second mechanical coupling for positive and/or non-positive coupling to the first mechanical coupling of the male interface device,
• wherein the central recess comprises another centring device configured to center the surgical assistance system free of play relative to the base of the male interface device,
• wherein the another centring device comprises a first functional surface, a second functional surface, and a third functional surface for contacting the corresponding first, second and third functional surfaces of the male interface device, and
• wherein the second mechanical coupling comprises at least a first displaceable bolt configured to engage a first undercut of the first mechanical coupling.
