Abstract: The invention relates to a disposable spoon with a bowl part (12) and, arranged thereon, a handle part (14) which comprises at least one hollow compartment (16, 18, 28) for accommodating and dispensing products, in particular foods or food ingredients, wherein the handle part (14) arranged on the bowl part (12) has a first hollow compartment (16) which is formed by an inherently rigid wall section, wherein the first hollow compartment (16) is assigned at least one further hollow compartment (18, 28), and wherein a predetermined breaking point for detaching the mutually assigned hollow compartments (16, 18, 28) is provided between the first hollow compartment (16) and at least one further hollow compartment (18, 28).

Abstract: To improve the reliability of a process for determining the position of a body part in which bone screws are screwed into the bone of the body part in question, each bone screw is provided with a radiation emitter or radiation receiver. A number of fixed receivers or emitters are used as appropriate to receive radiation from the bone screw transmitters or direct radiation towards the bone screw receivers. The radiation direction and/or radiation propagation time and/or radiation field strength or frequency is used to determine the position of each radiation emitter or receiver. A system for determining position based on this procedure and bone screws which can be used therefor are also disclosed.

Abstract: In order to reduce the risk that a bone screw, in particular one made of resorbing plastic material, with an externally threaded shaft will be destroyed by high screw-in torques, it is proposed that an insertion channel open at the top, arranged concentrically with the shaft and extending along most of the length of the shaft be located in the shaft for an insertion tool and have a cross-section which is non-circular and corresponds to the cross-section of the screwing-in tool.
