Abstract: A composite of polymer or ceramic material has reinforcing fibers. The composite is for use in manufacturing medical implants like osteosynthesis plates, endoprostheses, screw coupling elements, surgical instruments, and similar components. The fibers and fibrous parts are made from a material that absorbs X-rays so that it can be seen during X-ray examination.

Abstract: A method and apparatus for identifying a place where a saw may be performed. An oscillating laser beam is provided to a target according to a user preference. The user selects at least one characteristic of the oscillating laser beam in order to identify the target in an outdoor environment. The selected at least one characteristic is then provided to a motor which executes the oscillating.

Abstract: An osteosynthesis screw (1) used especially for application by a translaminar vertebral screw, comprises a shaft (3) at least partially provided with a thread (2) and a head (4) formed at one of its ends and having a notch (5) for a tool. Said shaft (3) has a section (A) with a thread (2) on the end section oriented towards the head (4). The remaining section (B) of the shaft (3) up to the free end is produced without a thread. The head (4) has a diameter (D1) corresponding at least approximately to the outer diameter (DA) of the thread (2) and is provided with the inner notch (5) for a tool. The section (A) of the shaft (3) with the thread (2) has a configuration of uniform thickness, e.g. a trilobular configuration. Thus, the invention provides an osteosynthesis screw (1) exhibiting a short section (A) with a thread (2) and a long section (B) without a thread, said screw having a pull-out head (4) which is secured both axially and rotationally.

Abstract: The invention relates to an osteosynthesis screw (1) comprising a shaft (3) with a thread (2) and a head (4) formed at one end and having a notch (5) for a tool. The shaft region (3) with the thread has a configuration with a uniform thickness, ie. trilobular.

Abstract: A seal body formed of a pot-shaped element or housing and a cover contains a compartment within which there is inserted a holder. The holder comprises a substantially U-shaped metallic element having leg members from which protrude resilient tongues directed away from the holder ends towards the center region of the holder. The tongues extend at an inclination towards the oppositely situated holder leg or leg member. For each leg member there are provided two tongues and, in each case, one of the tongues of one of the leg members intersects, in the hollow space between the leg members, with one of the tongues of the other leg member and forms a locking or blocking element. Coacting with such locking element are catch elements provided at both ends of a metallic strip. These catch elements are formed by openings.
