  • Patent number: 10159520
    Abstract: A device for fixing a femur for hip endoprosthesis surgery is disclosed. The device has a femur support including a hook configured to support the femur in a region of the femur between a greater trochanter and a lesser trochanter, and a shaft connected to the hook. A lever arm includes a column and a cantilever, wherein the femur support is disposed on the cantilever. An adjustment device is attached to an operating table. A holder is configured to couple the column of the lever arm to the adjustment device. The adjustment device has a drive motor for rotating the holder about an axis of rotation perpendicular to an adjustment plane to move the column in the adjustment plane. The adjustment plane is perpendicular to a support surface of the operating table and parallel to a longitudinal axis of the operating table.

  • Publication number: 20150094780
    Abstract: A device (10) for fixing a femur in hip endoprosthetics is described, comprising a femur support (18) having a bent hook part (36) that forms a supporting rest for the femur to be fixed in the region between greater trochanter and lesser trochanter, and having a shaft (38) connected to the hook part (36), a lever arm (20) having a column (22) and a cantilever (24), which has a receptacle (26) for attaching the shaft (38), an adjustment device (28) attached to an operating table (12) and a holder (30) coupleable to the adjustment device (28), at which holder (30) the column (22) of the lever arm (20) is attachable. The adjustment device (28) has a drive (32) for moving the column (22) in an adjustment plane, which is placed perpendicularly to the lying surface (16) of the operating table (12) and in parallel to the longitudinal direction thereof.

  • Publication number: 20120204351
    Abstract: In an X-rayable patient positioning plate with an outer shell, enclosing a hollow space filled with filler material, the shell consists of a tub-like upper part (36) and a tub-like lower part (38), each having a tub floor (40, 42) forming the plate top side and the plate bottom side, respectively, which forms with the tub margin (44, 46) an inner angle of more than 90°, while the top part (36) and the bottom part (38) are dimensioned and fitted into each other such that the tub margins (44, 46) of the two parts (36, 38) lie flat against each other and their tub floors (40, 42) bound the hollow space of the shell between them.

  • Patent number: 5611638
    Abstract: At least two connecting elements are fastened to the patient support and are insertable into pin receivers of the column and carriage. Each connecting element has two latching elements each movable between a latching position and an unlatching position, and during relative movement between the transport carriage and the support column resulting in the transfer of the patient support from the column to the transport carriage, or the reverse, each connecting element becomes received at the same time in a column pin receiver and a carriage pin receiver. Each receiver has a detent recess for receiving one of the latching elements of a received connecting element in its latching position and a control surface associated with the other latch element of the received connecting element which control surface upon the reception of the connecting element transfers this latching element to its unlatched position.
