Abstract: The present invention relates to an end-effector for a surgical, microsurgical or super-microsurgical robot arm, wherein the end-effector at least comprises: an end-effector base, and a first movable finger and a second movable finger extending from the end-effector base, the first and second movable fingers being configured and adapted to hold and manipulate at least one surgical instrument.

Abstract: The present application relates to a device for conveying flat pieces. The device comprises a belt with a transport surface, wherein the belt is movable along a transport axis; a support element with a support surface for supporting the belt; and a vacuum supply for providing vacuum suction; wherein a suction distributing structure at the support surface of the support element is in fluid connection with the vacuum supply; and wherein the suction distributing structure has a belt suction region and a card suction region, wherein the belt suction region is configured to provide suction to the belt and the card suction region is configured to provide suction to flat pieces on the transport surface of the belt. The present application also relates to a system for treating flat pieces, the system comprising a treatment device, for example a print head.

Abstract: A method for contactless cleaning of a nozzle plate of a print head. The method may include: providing a suction element, the suction element causing a fluid to flow along a surface of the nozzle plate and toward the suction element for removing residue from the nozzle plate; sucking-in, by the suction element, the fluid together with the removed residue; and separating the sucked-in fluid from the sucked-in residue. Also, a suction element for cleaning of such a nozzle plate. The suction element may be configured to cause a fluid to flow along a surface of the nozzle plate and toward the suction element for removing residue from the nozzle plate and sucking-in the fluid with the residue. The suction element may include a mouth piece and a wheel, the wheel being arranged such that the mouth piece is spaced away from the surface of the nozzle plate.
