A circuit board device includes a fixing member and a circuit board having a first hole. The fixing member includes abase having a second positioning portion and an opening, a first fixing component and a pillar structure having a first pillar body and a positioning pillar extending downward from the first pillar body and having a first positioning portion and a clamping portion. The clamping portion clamps the circuit board with the first pillar body when the first positioning portion is engaged with the first hole. The base is disposed in the first hole and abuts against the positioning pillar when the second positioning portion hooks the first hole and the opening is engaged with the positioning pillar. The first fixing component is detachably inserted into the pillar structure for clamping a first interface card with the first pillar body.

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.

An apparatus according to one embodiment includes a landing pad having a mating portion configured to mate with a mating feature of a removable element as the removable element approaches the landing pad in a first direction. The apparatus also includes a mount along which the landing pad is movable in a second direction. A lever is positionable between a disengaged position and an engaged position, the lever being coupled to the landing pad for translating the landing pad along the mount in the second direction during movement thereof from the disengaged position toward the engaged position. The first direction is different than the second direction.
