Medical mechatronic male and female interface device
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.
1. A medical mechatronic male interface device configured to couple a surgical assistance system to a mount, the male interface device comprising:
a base comprising an end face and a functional body extending from the end face;

wherein the functional body comprises a centering device configured to center the surgical assistance system free of play relative to the base,
wherein the centering device comprises a first functional surface, a second functional surface, and a third functional surface that together at least partially define a three-sided pyramid,
wherein the first mechanical coupling comprises a first undercut and a second undercut on the functional body, and
wherein the first undercut and the second undercut each define a segment engageable from behind.
2. The male interface device of claim 1 , wherein the first, second, and third functional surfaces are each inclined at least 20° relative to a central axis of the functional body.
3. The male interface device of claim 1 , wherein the first and/or second undercuts comprise a radially aligned opening such that the first and/or second undercuts are configured to radially engage a corresponding protrusion.
4. The male interface device of claim 1 , wherein the first mechanical coupling further comprises a third undercut on the functional body.
5. The male interface device of claim 4 , wherein the third undercut is substantially opposite the first and/or second undercuts and configured to radially engage a corresponding protrusion in a direction opposite the first and/or second undercuts.
6. The male interface device of claim 5 , wherein the third undercut of the functional body is disposed substantially centrally between the first and second undercuts.
7. The male interface device of claim 1 , wherein the first, second, and third functional surfaces radially taper off into a circumferential surface of a base body of the functional body.
8. The male interface device of claim 1 , wherein the first electronic interface is on the end face of the base.
9. The male interface device of claim 8 , wherein the first electronic interface comprises two or more blocks having electronic contacts.
10. The male interface device of claim 8 , wherein the first electronic interface comprises at least two grounding contacts disposed such that at least one of the at least two grounding contacts, when coupled to the female interface device, first comes into contact with at least one corresponding grounding contact of the female interface device before further electrical contacts are closed.
11. A medical female interface device configured to couple a surgical assistance system to a mount, the female interface device configured to be coupled to the male interface device of claim 1 , 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 centering device configured to center the surgical assistance system free of play relative to the base of the male interface device, and
wherein the another centering 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.
12. The female interface device of claim 11 , further comprising at least one second electronic interface configured to connect to the first electronic interface of the male interface device.
13. A surgical assistance system comprising the medical female interface device of claim 11 .
14. A passive adapter device comprising:
a bowl-shaped base body; and
the medical female interface device of claim 11 .
15. A mounting arm configured to mount a surgical assistance system, the mounting arm comprising:
a proximal end configured to attach the mounting arm to a base;
a distal end configured to receive the surgical assistance system;
two or more arm segments and two or more joints connecting the arm segments in an articulated manner;
a first interface at the proximal end configured to connect the mounting arm to a power source and to an external control unit that transmits signals to and from the mounting arm;
a second interface at the distal end configured to couple the mounting arm to the surgical assistance system for controlling the surgical assistance system; and
a transmission device disposed within the mounting arm and configured to connect the first interface to the second interface for transmitting energy and signals between the first and second interfaces,
wherein the second interface comprises the medical mechatronic male interface device of claim 1 .
