Abstract: An apparatus for the preparation of a femoral condyle for the insertion of monocondylar knee implants. In one embodiment, at least one combined cutting and drilling jig can be fixed to the femoral condyle, when the knee is in flexion, at a desired spacing from a tibia plateau dependent on the thickness of a tibia implant to be inserted. The jig can include a concave side facing the femoral condyle and curved in accordance with a femur implant to be inserted. The jig can further include at least one fixing passage in a drilling section of the jig for a drill and for a fixing element, with the fixing passage being positioned and orientated with respect to a curved side in accordance with the femur implant to be inserted.

Abstract: The invention relates to an apparatus for setting a cutting block having at least one guide surface for a resection of the tibia, the apparatus being capable of being anchored to the tibia in both an extramedullary and an intramedullary manner, and comprising a column which can be aligned with respect to the tibia and which is connected to a transverse arm provided for the anchoring at the natural tibia platform, with the cutting block being vertically adjustable relative to the transverse arm, wherein a carrier device which is vertically adjustable at the column is provided for the cutting block and has a joint arrangement by which different inclinations of the guide surface of the cutting block toward lateral/medial and/or toward posterior can be set.

Abstract: A pistol for the pressing out of bone cement (1) comprises an attachable cement syringe (2) which has a cylinder (3) with an ejection piston (4) and a narrower neck (5) which adjoins at the cylinder (3), with a displacer bar (6) being insertable into the pistol in order to additionally eject residual cement with a second advance mechanism (8). A first piston (9) acts via a piston rod (7) on the ejection piston (4). A second piston (11), which is displaceably journalled in the piston rod (7) and can be activated independently of the first piston, acts on the displacer bar (6). A fluid (10) which is under pressure is controlled via a control device (12) in such a manner that the displacer bar (6) moves relative to the first piston (9) only when the latter has reached a predetermined end position.

Abstract: The ink reservoir comprises a bottle (1) into which is installed a foil bag (2). The bag (2) is designed at both axial ends as a standing bag. In one end of the bag (2) includes a thermoplastic connector (23) having an elastomer stopper (27) disposed therein. The stopper is piercable by a first hollow needle of the plotter. The connector (23) is snapped into a lid (4) of bottle (2) below a passage opening (44). The lid (4) is snapped onto the bottle (1). Below the lid (4), an absorbent body (3) is installed in the bottle (1) which surrounds the bag. By means of another opening (45) in lid (4) a second hollow needle of the plotter is inserted into the absorbent body (3). The absorbent body serves for acceptance of waste ink. With the described design, one attains simple handling during shipping and installation in the plotter.

Abstract: An ink receptacle includes a housing (1) having a tub-shaped bottom part (2) and a lid (3). Around the periphery of an upper edge (16) of the tub (4) extends a circumferential groove (17). A port (8) sealed by a stopper (10) is defined in the bottom (7) of the tub (4) which is adapted to be pierced by a hollow needle. A tub-shaped membrane (18) is installed in the tub (4) and has, at its edge, a bulge (20) which is fitted with radial compression in groove (17). The lid (3) is snapped onto the bottom part (2) and has an interior wall (36) whose lower edge is pressed upon the bulge (20). In addition to the tub (4), the receptacle has another chamber (26) with an absorbent filling (28) for acceptance of residual ink. The receptacle has a large volumetric capacity and is specifically suitable for plotters or printers.
