Patent number: 9872687Abstract: The nucleotomy device makes it possible to produce a nuclear space Es in an intervertebral disc Di using a transosseous approach previously pierced in the body of a vertebra Va. The device includes a tool holder (2) provided with first connection elements (3) ensuring the placement of an electric rotary driving motor (4), second connection elements (5) for the placement of a blade cutting tool (6), driving elements (7) imparting rotational and longitudinal translational movements to the cutting tool (6), and injection and suction elements (8) making it possible to evacuate the debris from the nucleus resulting from cutting when it is formed inside the intervertebral disc.Type: GrantFiled: July 19, 2013Date of Patent: January 23, 2018Assignee: CLARIANCEInventors: Alain Tornier, Guy Viart, Jean Yves Leroy, Adrien Billon, Brice Krier, Sebastien Shuller, Afshin Gangi, Orlando Ortiz

Publication number: 20170319251Abstract: The secured guiding device for positioning and guiding a bone anchoring screw during a surgical procedure according to the present invention, includes a guide pin having a deformable bifid free end which is elastically deformable and consists of two blades having, on the one hand, a first so-called “closed” configuration obtained, for example, by a manual stress so as to position the blades in the prolongation of the longitudinal axis of the guide pin so that the latter can be introduced into a guide tube for its positioning at the surgical site and, on the other hand, a second so-called “open” configuration so as to position the blades in two opposite directions and substantially perpendicular to the longitudinal axis of the guide pin when the blades are outside the guide tube in order to provide a bone support during the positioning of the anchoring screw.Type: ApplicationFiled: November 9, 2015Publication date: November 9, 2017Inventors: Guy VIART, Jean Yves LEROY, Brice KRIER, Sebastien SHULLER
