Title (EN) SURGICAL UNIVERSAL POSITIONING BLOCK AND TOOL GUIDE
(FR) BLOC DE POSITIONNEMENT CHIRURGICAL UNIVERSEL ET GUIDE D'OUTIL
Abstract:
(EN) A positioning block (10) for use in total knee replacement surgery, permitting five degrees-of-freedom movement relative to a bone element (39) to which it is fixed. The positioning block (10) comprises a mounting member (14) including a fastener receiving mount element (24) by means of which mounting member (14) is removably engaged to the bone element such that the mounting member (14) is selectively rotatable relative to the bone element, about three substantially perpendicular axes of rotation. Fastener receiving mount element (24) slides within a central guide slot (22) disposed within a mounting member body (20) which also forms part of mounting member (14) A guide body portion (12) is engaged with the mounting member (14) such that it is translatable relative there to along a proximal-distal axis (43) and together with the mounting member-body(20) is translatable relative to the fastener receiving mount element(24) along an anterior-posterior axis (47), while being rotationally fixed relative to the mounting member(14) such that the guide body portion(12) and the mounting member(14) rotate together relative to the bone element(39). Computer means identify and display the position of the positioning block(10).
(FR) L'invention concerne un bloc de positionnement (10) s'utilisant en arthroplastie totale du genou, qui permet d'effectuer un mouvement à cinq degrés de liberté par rapport à un élément osseux (39) auquel il est fixé. Le bloc de positionnement (10) comprend un élément de fixation (14) rotatif qui s'assemble amovible à l'élément osseux, de sorte que l'élément de fixation (14) peut tourner de manière sélective par rapport à l'élément osseux autour de trois axes de rotation sensiblement perpendiculaires. Une partie corps de guidage (12) est mise en contact avec l'élément de fixation (14) de façon à pouvoir effectuer un mouvement de translation par rapport à celui-ci le long d'un axe proximal-distal (43) et d'un axe antérieur-postérieur (47), cette partie étant fixée en rotation par rapport à l'élément de fixation (14), de sorte que la partie corps de guidage (12) et l'élément de fixation (14) tournent ensemble par rapport à l'élément osseux (39).
