Abstract: A medical mechatronic male interface device couples a surgical assistance system to a mount. The male interface device includes a base including 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. The functional body includes a centering device that centers the surgical assistance system free of play relative to the base. The centering device includes a first functional surface, a second functional surface, and a third functional surface that together at least partially define a three-sided pyramid. The first mechanical coupling includes a first undercut and a second undercut on the functional body that each define a segment engageable from behind.

Abstract: A surgical manipulator device for positioning a surgical instrument has a frame, a first mount, a second mount, a first suspension arm arrangement supported on the frame and connecting the frame to the first mount in an articulated manner, and a second suspension arm arrangement supported on the frame and connecting the frame to the second mount in an articulated manner. The first and the second suspension arm arrangements are each displaceable relative to the frame in first and second motion planes parallel to each other and spaced apart, so that the first mount is displaceable in the first motion plane and the second mount is displaceable in the second motion plane.

Abstract: A medical mechatronic male interface device for coupling a surgical assistance system to a mounting structure has a base with an end face, a functional body, extending from the end face, first mechanical coupling means for positive and/or non-positive coupling to a corresponding medical mechatronic female interface device, and at least one first electronic interface for connecting to a corresponding second electronic interface of the female interface device. The functional body has a centring device to center the surgical assistance system free of play relative to the base. The centring device has a first functional surface, a second functional surface, and a third functional surface that are not parallel to each other and that have normals which do not lie in a common plane. A corresponding female interface device and a mounting arm and a surgical assistance system are also described.
