Patent number: 10765412Abstract: The invention relates to an endoscopic instrument (1) having an elongate body with a distal end (4) designed to be introduced into the body of the patient so as to come into proximity with an internal organ, the distal end carrying a tool (7) for intervention on the internal organ. The endoscopic instrument has a fool (10) rigidly connected to the distal end and designed to bear on the internal organ, and also controllable means (13) for conferring movements on the tool, at least in directions transverse to a longitudinal axis (X) of the distal end of the endoscopic instrument, when the foot is bearing against the internal organ.Type: GrantFiled: June 25, 2012Date of Patent: September 8, 2020Assignees: UNIVERSITE PIERRE ET MARIE CURIE (PARIS 6), CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, MAUNA KEA TECHNOLOGIES, ENDOCONTROLInventors: Benoît Rosa, Benoît Herman, Jérôme Szewczyk, Guillaume Morel, Clément Vidal, Patrick Henri, François Lacombe, Jérôme Lopez

Patent number: 10582977Abstract: The invention relates to a device and a method to assist with the operation of an instrument by means of said device, the device and the method using leverage effects in order to calculate the data relative to any point of an instrument axis, instead of using low-accuracy sensors. Other improvements are also described that allow higher-quality usage performance for the operator, which reduces the risk of errors and simplifies the operations.Type: GrantFiled: February 5, 2016Date of Patent: March 10, 2020Assignees: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (CNRS), SORBONNE UNIVERSITE, ENDOCONTROLInventors: Guillaume Morel, Lin Dong, Florian Richer, Nicolas Perrin, Clément Vidal, Bérengère Bardou

Patent number: 9655499Abstract: A miniaturized scanning system to generate movement of a flexible device positioned at a distal part of a medical tool. The miniaturized scanning system includes an inner shaft with a longitudinal axis, adapted to guide said flexible device along the longitudinal axis, an abutment comprising an external surface and adapted to maintain said device, and a pusher mechanism adapted to engage with said abutment. The miniaturized scanning system includes at least one end portion adapted to contact said external surface of the abutment at a contact point, wherein said end portion is configured to translate along said longitudinal axis of the inner shaft and wherein the translation of said end portion results in a bending of the device in a bending plane defined by the longitudinal axis of the inner shaft and said contact point.Type: GrantFiled: April 8, 2013Date of Patent: May 23, 2017Assignees: Mauna Kea Technologies, EndoControl, Universite Pierre Et Marie Curie, Centre National De La Recherche Scientifique-CNRSInventors: Mustafa Suphi Erden, Benoit Rosa, Jérôme Szewczyk, Guillaume Morel, Clément Vidal, Patrick Henri, Nicolas Boularot

Patent number: 8961499Abstract: A surgical instrument having an elongated arm and a distal end mounted with a pivot joint on the elongated arm. A drive shaft substantially coaxial with the elongated arm forms a universal joint facing the pivot joint. A distal tool is securely fastened on the drive shaft and rotatively mounted on and in the extension of the distal end of the elongated arm, such that the distal tool has two rotational degree of freedom, distinct and independent of each other, one being around an axis substantially perpendicular to the longitudinal axis of the elongated arm and the other being around an axis substantially collinear to an own axis of the distal tool. The elongated arm includes a plurality of linking elements mounted in series to form the pivot joint. The universal joint is a Cardan joint.Type: GrantFiled: April 2, 2010Date of Patent: February 24, 2015Assignees: Universite Pierre et Marie Curie (Paris 6), Endocontrol, Centre National de la Recherche Scientifique (CNRS)Inventors: Jamie Paik, Guillaume Morel, Clément Vidal, Patrick Henri, Hervé Collet
