    摘要: Dynamic, flexible wrought Nickel/Titanium alloy spinal rods for spinal fusion or dynamic stabilization vertebral implants and methods and processes related to their manufacture. The dynamic and flexibility properties of the wrought Nickel/Titanium alloy spinal rod may be varied by altering processing parameters during manufacture that develop the shape memory characteristics, mechanical properties, and product workability characteristics to achieve custom manufacture of spinal rods having desired flexion in desired lengths. Such a custom manufactured spinal rod may be affixed to an inferior vertebral body at a standard lamina or pedicle location and to one superior vertebral body at a standard lamina or pedicle location using pedicle screws, lamina hooks, or pedicle hooks to provide dynamic stabilization between superior and inferior vertebrae in connection with a spinal fusion procedure.

    摘要: The present invention discloses a method for removing iodine compounds from acetic acid, in which the iodine compound is removed by using a solid adsorbent in the form of an activated carbon fiber having a large strength, a large bulk density, and a large specific surface, so that the treatment of large amounts should be possible, that the acetic acid should not be contaminated during the extraction of foreign materials from the adsorbent, and that the adsorbent can be repeatedly used by regenerating it. The method includes the steps of: preparing a filter in the usual manner by using an activated carbon fiber as the adsorbent; and making acetic acid containing an iodide pass through the activated carbon fiber filter, whereby the iodide in acetic acid is removed by being adsorbed by the activated carbon fiber filter.

    摘要: Apparatus, systems and methods for decompression and dynamic stabilization of the vertebrae. A flexion construct is formed from a medial loop of a cylindrical member in a first plane that is generally parallel to the long axis of the member, and two outlying loops, generally residing in a common second plane that is generally parallel to the long axis of the member and generally perpendicular to the first plane formed by the medial loop. The medial loop and outlying loops of the flexion construct may aid in controlling distraction, compression and flexion of the assembly. Multiple level constructs may include multiple sets of loops, one set for each spinal level. The member may also include two legs that terminate in hooks or include a straight portion for attachment by another attachment means. A protective sleeve may be used between the member and any attachment means.
