    摘要: 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.

    摘要: 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. This configuration prevents inverse rotation due to rapid further growth of tissue

    摘要: 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. If one end of the strip is introduced into a receiving opening of the seal body and which opening is accommodated to the dimension of the strip end, and into the space between the leg members of the holder, then the opening is caught at the tongues of the one locking element and no longer can be retracted. To close the seal the other end of the metallic strip is guided into the seal body between the tongues of the other locking element until it is irreversibly caught by means of its strip opening in the same manner.
