摘要： One aspect relates to a device for producing a bone cement paste from a monomer liquid and a cement powder as parent components of the bone cement paste and for delivering the mixed bone cement paste. The device has a cartridge with a cylindrical interior. The interior of the cartridge is closed at a front side apart from a delivery opening for discharging the bone cement paste. In the interior of the cartridge a delivery plunger is arranged which is pushable in the direction of the delivery opening. The cement powder is arranged in the interior of the cartridge between the delivery opening and the delivery plunger. A hollow cylinder is arranged at a front side of the delivery plunger facing the delivery opening. The hollow cylinder is open at its front face facing the delivery opening and extends from the front side of the delivery plunger at least 3 mm into the interior of the cartridge.

摘要： A storage and mixing system for pasty two-component polymethyl methacrylate bone cements comprises a tubular cartridge having a cylindrical inner chamber, a dispensing plunger that is axially displaceable in the inner chamber of the cartridge, a partition disposed axially in the tubular cartridge, and a cartridge head which closes one end of the tubular cartridge. The cartridge head has a slot-shaped opening, wherein the partition protrudes from the inner chamber of the cartridge through the slot-shaped opening of the cartridge head, wherein the partition divides the cylindrical inner chamber of the cartridge bounded by the dispensing plunger and the cartridge head into two cavities that are spatially separated from one another. A first pasty cement component is present in the first cavity and a second pasty cement component is present in the separate second cavity, wherein the partition is removable through the slot-shaped opening of the cartridge head so that the two separate cavities are connected to one another after the partition is removed.

摘要： A modular articulated spacer system provides for screw-based assembly of an articular spacer intended to replace an artificial joint temporarily, whereby the articulated spacer system comprises at least two modules connectable by means of a screw connection, whereby a first module of the articular spacer system comprises a surface for formation of a sliding surface of the joint of the articular spacer and a second module of the articular spacer system comprises a stem for connection to a bone. The modules are connectable by means of the screw connection comprising at last one screw-locking device for each screw connection, whereby the screw-locking device is connected to one of the modules or is provided in the form of the same part as one of the modules. A method builds-up an articular spacer using said articulated spacer system, in which the articular spacer is screwed together using at least two modules, whereby the modules are screwed together appropriately such that the screw-locking devices prevent the modules from detaching or being unscrewed.

摘要： The invention relates to an articulating joint spacer for temporary replacement of a joint, whereby the joint spacer comprises two spacer parts which each comprise one sliding surface on which the spacer parts, in the patient-inserted state, touch against each other in mobile manner and roll off on each other, and the remaining spacer parts are made, at least in part, of a second bone cement that contains at least one water-soluble antibiotic. The invention also relates to a method for producing a two-part articulating joint spacer, in which a sliding surface is formed in both spacer parts from a low-abrasion first bone cement and at least the surfaces of the remaining spacer parts, at least 50% thereof, are formed with a second bone cement that contains at least one water-soluble antibiotic.

摘要： A vacuum motor comprising a working plunger, an internal space, in which the working plunger is arranged such that it is mobile in linear direction, a resetting element that exerts, at least for part of the time, a force on the working plunger that acts in the direction of a front side of the internal space, a gas inlet opening for supplying ambient air or a compressed gas into the internal space, and a gas outlet opening for discharging the gas from the internal space. The gas outlet opening is connectable to a negative pressure source, whereby a control plunger is arranged between the working plunger and a rear side of the internal space such as to be mobile in linear direction in the internal space. The control plunger is supported as in a bearing such as to be mobile with respect to the working plunger, and a catch element and/or a spacer is arranged on said working plunger and/or control plunger, whereby the catch element, upon a motion of the working plunger towards the front side of the internal space, transfers the control plunger into the first position, and whereby the catch element or the spacer, upon a motion of the working plunger towards the rear side of the internal space, transfers the control plunger into the second position.

摘要： An antiseptic composition for use as bone cement, in particular an antiseptic polymethylmethacrylate bone cement. The composition can be cured and comprises a pharmacologically tolerable salt of a monoperoxy dicarboxylic acid, whereby the salt of the monoperoxy dicarboxylic acid can be dissolved from the composition in the presence of water. Preferably, the salt of the monoperoxy dicarboxylic acid in the composition is used in the form of a powder, whereby the powder has a mean particle size of not more than 250 μm. Preferably, the salt of the monoperoxy dicarboxylic acid, in solution at room temperature, is not degraded within 5 min by the catalase enzyme.
