摘要： A differential pressure motor comprising two working pistons and a rod that move in a hollow space. Walls defining the hollow space have five openings. A valve piston moves between and against the working pistons and can be driven by the working pistons. The valve piston with the five openings forms a valve with which an alternate impact of a first pressure and a second pressure on the working pistons is controllable when the pressures are applied to three of the five openings such that the working pistons periodically move which drives a periodic movement of the valve piston. Also disclosed are a surgical drive system with, a medical lavage system for the debridement of soft tissue and/or bone tissue having, and a medical device for brushing, rasping or sawing soft tissue and/or bone tissue with such a differential pressure motor, and a method for operating a differential pressure motor.

摘要： One aspect relates to a device for mixing two liquids including a tube having an open end, a main line connected to the tube in a liquid-permeable manner, a rubber-elastic body delimiting a line wall of the main line, at least one secondary line in the rubber-elastic body, wherein the at least one secondary line extends from at least one secondary opening up to the main line and opens via at least one mouth into the main line, a main connection for introducing a first liquid into the main line, at least one feed line for introducing a second liquid into the at least one secondary line, which is connected to the at least one secondary opening in a liquid-permeable manner. The at least one secondary line is closed in the rubber-elastic body without the action of a force and is hydraulically openable by a pressure being exerted on a second liquid fed to the at least one secondary line by an elastic deformation of the at least one rubber-elastic body. The open at least one secondary line closes without a pressure being exerted on the supplied second liquid by the restoring force of the elastically deformed rubber-elastic body.

摘要： A storage and mixing device for PMMA bone cements having a cylindrical interior of the cartridge that is delimited on a front side by a cartridge head with a closed delivery opening, a plunger which is arranged to be axially movable in the cylindrical interior of the cartridge and which is spaced from the cartridge head. The plunger circumferentially rests against the inner wall of the interior, so that the plunger divides the interior of the cartridge into two sections in a gas-tight manner, a powdery first parent component of the bone cement, which is contained in the interior between the plunger and the cartridge head, a feed-through which is arranged in the cartridge head or in the cylinder barrel of the cartridge between the plunger and the cartridge head, wherein the feed-through is connected to a fluid line in which a monomer liquid as a second parent component of the bone cement is contained or into which a monomer liquid is fillable or introducible. A filter is arrangeable in the cartridge head, in the feed-through and/or in the fluid line, wherein the filter is permeable to the monomer liquid and impermeable to the first parent component, wherein the plunger is spaced from a back side of the cylindrical interior, located opposite the front side, to an extent that, by moving the plunger in the direction of the back side, a reduced pressure is producible in the interior of the cartridge between the plunger and the cartridge head, wherein the reduced pressure is able to suck the monomer liquid out of the fluid line into the interior of the cartridge.

摘要： Bone cement applicators and methods for application of a bone cement dough, the applicators and methods comprise a tubular cartridge with an internal space, a dispensing plunger for expelling the starting components through an opening of the cartridge opposite from the dispensing plunger, wherein the dispensing plunger is mobile in longitudinal direction in the internal space of the cartridge. The applicators and methods further comprise a hose, an application opening, a three-way valve operable from outside and arranged or arrangeable in the hose or on a side of the hose facing the cartridge, and a collecting container arranged on the three-way valve. The three-way valve is designed and arranged or arrangeable in the applicator such that it, being in a first position, provides a fluid connection between the application opening and the opening of the cartridge and closes a feed-through to the collecting container and, being in a second position, provides a fluid connection between the application opening and the collecting container and closes a passage to the opening of the cartridge.

摘要： Storage and mixing systems for pasty two-component polymethyl methacrylate bone cements comprise a tubular cartridge having a cylindrical inner chamber, a cartridge head, which closes one end of the tubular cartridge at the front side, a partition that is disposed axially in the cylindrical inner chamber of the cartridge. The partition divides the cylindrical inner chamber of the cartridge bounded by the cartridge head into two cavities that are spatially separated from one another, wherein a first pasty cement component is present in the first cavity and a second pasty cement component is present in the separate second cavity. The systems further comprising two dispensing plungers axially displaceable in the two cavities of the cartridge, wherein the dispensing plungers close the two cavities on the back side of the cavities situated opposite the cartridge head, a bending device for deforming the partition, wherein the bending device is axially movable in the cartridge and is disposed, or is to be disposed, behind the dispensing plungers, as seen from the cartridge head, wherein the bending device has a deflection surface that is inclined with respect to the axis of the cartridge and pushes the partition laterally in the direction of the inside wall of the cartridge when the bending device is pushed into the cartridge.
