Title
(EN) METHOD AND APPARATUS FOR STRENGTHENING THE BIOMECHANICAL PROPERTIES OF IMPLANTS
(FR) PROCEDE ET APPAREIL DE RENFORCEMENT DES PROPRIETES BIOCHIMIQUES D'IMPLANTS
Abstract
(EN) A method for agitating a surgical fluid (40) using a vibrating probe is disclosed. The agitation method drives entrapped air voids (44) out of the surgical fluid and forces the fluid into a plurality of pores (130) of various sizes in the adjacent bone (100). The vibrating apparatus (10) in one embodiment includes a probe tip (30) disposed upon a graspable elongate shaft (20) and a series of fins (34) extending into the fluid. The apparatus in one embodiment may include a set of probe tips of different shapes and sizes. The agitation and interdigitation method may facilitate any procedure involving any type of surgical fluid, with or without a prosthetic device such as an intramedullary nail (356) or femoral prosthesis (358).
(FR) L'invention concerne un procédé permettant d'agiter un fluide chirurgical (46) au moyen d'une sonde de vibration. Le procédé d'agitation entraîne des vides d'air piégé (44) hors du fluide chirurgical et pousse celui-ci dans une pluralité de pores (130) de tailles différentes dans l'os adjacent (100). L'appareil de vibration (10), dans un mode de réalisation, comporte un bout de sonde (30) au-dessus d'une tige allongée saisissable (20) et d'une série d'aubes (30) s'étendant dans le fluide. L'appareil, dans un mode de réalisation, peut comporter un ensemble de bouts de sonde de différentes formes et tailles. Le procédé d'agitation et d'interdigitation peut faciliter toute opération impliquant un quelconque fluide chirurgical, avec ou sans prothèse, notamment un clou médullaire (356) ou une prothèse fémorale (358).
