  • Publication number: 20200352564
    Abstract: A surgical staple insertion system for compressing bone fragments includes a staple and an insertion tool. The staple has first and second legs and an elastically deformable bridge monolithically formed with the first and second legs. In a relaxed configuration, the free ends of the first and second legs are positioned closer to one another than are portions of the first and second legs connected to the bridge. The insertion tool retains the bridge in an elastically deformed configuration with the legs positioned relatively farther apart from one another during at least portion of the step of implantation of the staple. Then, the insertion tool is released from the staple so that the bone fragments between the legs are subject to compression.

  • Patent number: 10792075
    Abstract: An element with a shank (1) and a holding element (2) connected to it for connecting to a rod (100) is provided, wherein the holding element (2) has a recess (3) having a U-shaped cross-section for receiving the rod (100) with two legs (4, 5) open at one end (6) and an inner thread (7) on the open legs (4, 5) and a locking element (9) with an outer thread (8) which cooperates with the inner thread of the legs, wherein the inner thread (7) of the legs and the outer thread (8) of the locking element are constructed with a flat thread in which the two flanks (7a, 7b; 8a, 8b)) enclose an angle of 90° in each case with the screw axis (S, M). This prevents splaying of the open legs when the locking element is screwed in. The flat thread is easy to produce.
