The running wheels (1, 2, 3) are suspended on wheel suspension units (20) and are arranged in a triangle in relation to one another, in such a way that the first running wheel (1) runs on a first rail (14) and the second running wheel (2) and the third running wheel (3) run one behind the other on a second rail (16). The rails (14, 16) form a runway (10) for the traveling cleaner (12) and are arranged next to one another above textile machines of the textile manufacturing plant.

Abstract: An insertion instrument for a pair of sliding prostheses, said instrument having, on a supporting plate (2), two clamps which are each intended to receive a sliding prosthesis and whose spacing is adjustable. The clamping jaws (10, 11) of the clamps have projections (18) which interact with the side edges of the sliding prostheses to provide positioning. Two vertically adjustable slide-surface supports (6) are provided. According to the invention, in order to adjust the spacing between the clamps on the supporting plate (2), a slide guide with adjustment spindle (22) is provided, and the slide-surface supports (6) are arranged in a fixed position on the supporting plate (2). They have a width which is large enough to support the sliding prostheses in any chosen spacing.

Abstract: A prosthesis system consisting of an endoprosthesis with a shank which is to be introduced into the medullary canal of a bone, and of a rasp (20) which is similar in shape to the shank and is used to prepare a cavity for receiving the shank. Along much of its length, the rasp has an untoothed profile part (25) which, instead of excavating the spongy bone substance, compacts the latter and thus ensures a secure fit of the prosthesis. In the area corresponding to the untoothed area of the rasp (20), the prosthesis shank preferably has a rib which cuts like a wedge into the compacted spongy substance.

Abstract: An implant, in particular an intervertebral endoprosthesis, with a connection plate (3) which is to be fixed so as to bear on a bone surface and which is to be applied to the bone surface in a direction of application running transverse to its main extension. For protection against a shearing force running parallel to its main extension, the connection plate (3) has teeth (6) projecting in the direction of application. These teeth (6) are delimited by surfaces (11, 12, 13) which include a main surface (11) arranged in the direction of application and transverse to the direction of shearing. Two teeth or groups of teeth in each case lie opposite one another in the direction of shearing and point in opposite directions.

Abstract: A cotyloid cavity prosthesis consists of an outer shell (1) and a bearing insert (2) held together by a locking device (3). The locking device comprises an elastic lip (6) and an undercut surface (4) interacting with the latter. The dimensions are chosen such that, once mounted, the tip (9) of the lip rests on the undercut surface (4), with bending deformation of the lip (6). In order to accomplish the latter, the undercut surface (4) forms a smaller angle with the center axis of the prosthesis than does the deformation line of the tip (9) of the lip.

Abstract: Disclosed is a device for securing a bone during surgery. The devices includes a band portion, a tightening buckle, and a tightening shaft. The band portion can be wrapped around a bone during surgery to secure the bone. The tightening buckle and tightening shaft are used to fasten the band portion. The tightening buckle has a wall with a tooth for engaging the tightening shaft.

Abstract: A plastic implant has a circumferential channel (3) for receiving a radiographic contrast wire (9). The channel (3) is completely or partially closed off from the outside. The wire advantageously forms an open loop.

Abstract: An acetabular cup is supported by a pelvic bone and includes an outer surface which rests in a cavity, and a bearing surface which receives an articular body of an artificial hip joint and bounded in surrounding relation by a receiving edge. The receiving edge is provided at least at one area with an elevation which partially surrounds the articular head received by the bearing surface. The elevation is provided at a location in which the articular head is least obstructed in its freedom of movement, and has at its apex projecting furthest from the receiving edge a distance from a lowest point of the bearing surface which guides the articular head in substantially surrounding relation.

Abstract: A hip-joint endoprosthesis with a stem to be anchored in the femur, and with a joint head supported by the stem via a neck. In order, upon implantation, to be able to use one and the same prosthesis with a different choice of resection plane within the neck of the head, the stem of the prosthesis is curved in a substantially uniform circular arc; the neck adjoins the upper end of the stem approximately in the same direction; the length of the stem is not greater than 150 mm; and the hip-joint endoprosthesis, while keeping the same stem shape, is available with different neck lengths, of which several are smaller than the length of an average natural femoral neck.

Abstract: An endoprosthesis for replacing at least part of a tibia, includes an elongate shaft extending longitudinally in the direction of a lower leg and having an upper end facing a knee joint and a lower end facing a natural talus. An endoprosthetic knee joint having a tibial plateau is secured to the upper end of the shaft. The talus supports a coupling portion which is connected to the lower end of the shaft.

Abstract: A surgical instrument includes a stem to be inserted into the medullary cavity of a proximal femur and a grip part slightly offset from and extending approximately parallel to the direction of the stem. The grip part is releasably connected to the upper end of the stem by mutual coupling parts including a peg protruding obliquely from the upper end of the stem and a bore located in the lower end of the grip part. Releasable means for arresting the peg in the bore are formed by the end of a rod which is guided movably in the longitudinal direction of the grip part and by a recess in the peg for receiving this end. The recess in the peg is a continuous bore and the rod, in its arrested position, extends completely through the bore. The upper end of the rod is connected to a handle located in the middle to upper region of the grip part. The rod or the handle is provided with a catch mechanism for securing the rod in the arrested position.

Abstract: The present invention provides an endoprosthesis for a joint between two bones which cannot be distracted, or which can be distracted only with difficulty. A suitable joint for the endoprosthesis is the sternoclavicular joint. The endoprosthesis has two components, one of which may be attached to the collar bone, and the other which may be attached to the breastbone. One component has a joint head which is insertable into the enclosure part of the second component. The joint head on one component is introduced from the side of the enclosure part on the second component by means of a lateral installation opening in the enclosure part. This arrangement allows little or no distraction of the bones to which the endoprosthesis components are attached when the components are connected.

Abstract: An endoprosthesis adapted for permitting the disconnection of components of the endoprosthesis from one another for the purpose of providing mutual position securing includes a first component having a connection plug and a second component having a connection bore for receiving said connection plug. The first component also has a securing bolt within a bolt bore in the first component, and the second component has a recess formed therein for receiving part of the length of the securing bolt. The securing bolt is brittle or soft or has a predetermined break point selected so that a load that breaks or shears off the securing bolt is of an amplitude not to be expected during normal use of the endoprosthesis.
