Title
(EN) TOOLS AND METHODS FOR CREATING CAVITIES IN BONE
(FR) OUTILS ET PROCEDES PERMETTANT DE CREER DES CAVITES DANS DES OS
Abstract
(EN)
Tools are disclosed for use in the creation of cavities in bones. The tools include a probe (10), a cannula (34) that provides percutaneous passageway to the interior of the treated bone, a bone tamp (44), and a system for delivering bone filler material into the cavity. The bone tamp (44) has a shaft that is inserted into the bone through the cannula (34). The end of the shaft that is inserted into the bone may have a flapper tip that extends out of axial alignment with the shaft upon deployment by the physician. Once the tip is deployed, the bone tamp (44) can be rotated to form the cavity. The cavity may then be treated with a medicament, filled with bone filler material, or both. Other tools and materials described herein may be used to lift or restore the treated bone closer to its natural anatomy.
(FR)
L'invention concerne des outils à utiliser dans la création de cavités dans des os. Les outils comprennent une sonde (10), une cannule (34) qui fournit un passage percutané à l'intérieur de l'os traité, un pilon à os (44) et un système d'administration de la matière de comblement osseux dans la cavité. Le pilon à os (44) comporte une tige introduite dans l'os par la cannule (34). L'extrémité de la tige introduite dans l'os peut comporter un embout à clapet qui s'étend hors d'alignement axial par rapport à la tige lorsque le médecin le déploie. Une fois que l'embout est déployé, le pilon à os (44) peut être tourné pour former une cavité. Celle-ci peut alors être traitée avec un médicament et/ou remplie d'une matière de comblement osseux. D'autres outils et matières décrits dans la présente invention peuvent être utilisés pour restaurer l'os plus proche de son anatomie naturelle.
