Patent number: 10682148Abstract: The invention concerns a system for partially cutting a bone, comprising a device for guiding a cutting tool. According to the invention, the device comprises: —an upper face forming a mechanical stop for a first part of the cutting tool, the upper face being non-cutting and thicker than the blade, so as to limit the insertion of the blade into said bone in order to partially cut said bone, the upper stop face having a profile that is a homothety of the edge profile of said hinge, the guide device having a pre-defined range to ensure the steering of the blade of the cutting tool in a pre-defined direction of partial cutting of the bone, —a second part that fastens to the bone and a first fastening means for fastening the guide device to the second part and —a means for adjusting the orientation of the guide device relative to the second part.Type: GrantFiled: December 10, 2013Date of Patent: June 16, 2020Assignee: OSTESYSInventors: Pierre-Yves Huet, Guillaume Dardenne, Stephane Lavallee, Eric Stindel, Christian Lefevre

Patent number: 10092305Abstract: The invention relates in particular to a system for attaching a first bone segment to a second bone segment, the two segments belonging to the same bone, in which the first and second segments are held together via a hinge resulting from the partial transverse cutting of said bone, characterized by the fact that said system comprises: two targets suitable for attaching to the two segments of said bone; a navigation system suitable for acquiring the three-dimensional positions and orientations of the targets; —a processing system suitable for calculating, based on the data sent from the navigation system, the angles corresponding to the three-dimensional alignment of said two segments; a display unit suitable for displaying the information to the surgeon; at least one milling guide; a plurality of implants of different sizes.Type: GrantFiled: July 26, 2013Date of Patent: October 9, 2018Assignee: OSTESYSInventors: Guillaume Dardenne, Pierre-Yves Huet, Stephane Lavallee, Christian Lefevre, Eric Stindel, Romain Gerard

Publication number: 20180000447Abstract: An ultrasound measuring device includes: a support bearing two ultrasound probes movable relative to each other by slide link, each of the two probes being movable relative to the support by ball-joint link, wherein the probes are capable of simultaneously acquiring two ultrasound images. The device includes a first set of measuring elements to measure a relative positioning of the probes, including one travel sensor and at least two orientation sensors. The device includes a second set of measuring elements to measure a positioning of the device relative to a reference plane, including at least one orientation sensor. The device localizes at least one point of interest on each of the two ultrasound images, and processes data coming from the first and second measuring elements, delivering a relative spatial position of the points of interest located in the images.Type: ApplicationFiled: December 17, 2015Publication date: January 4, 2018Inventors: Eric Stindel, Manuel Urvoy, Guillaume Dardenne, Julien Leboucher, Shaban Almouahed

Publication number: 20170014138Abstract: The invention relates to an instrument (1) for positioning osteotomy tool-holder baseplates (E1, E2). According to the invention, the instrument contains two supports (2, 3) of said baseplates, connected together by a connecting part (4) in a semi-rigid material allowing relative displacement of one of the supports (2, 3) with respect to the other (3,2).Type: ApplicationFiled: February 19, 2015Publication date: January 19, 2017Applicant: OSTESYSInventors: Pierre-Yves HUET, Guillaume DARDENNE, Eric STINDEL

Patent number: 8731253Abstract: A system and method are provided for helping implant a hip prosthesis in an individual, which includes an acetabulum intended to be placed in the hip bone of the patient and a femoral part intended to be integrally connected to the femur of the individual. The method includes: obtaining, before the operation, images issued by a device that images a human body and locates a position of images in space. The images are taken in at least three reference positions: standing; recumbent; and sitting. Before the operation, the method determines a pelvis version of the individual in different positions by analyzing the images. During the operation, the method measures a position of the acetabulum with relation to the pelvis of the individual, and simultaneously restores information representative of prosthetic mobility of the hip with relation to each of the reference positions, for a current position of the acetabulum.Type: GrantFiled: June 19, 2009Date of Patent: May 20, 2014Assignee: Universite de Bretagne OccidentaleInventors: Guillaume Dardenne, Eric Stindel, Chafiaa Hamitouche, Christian Roux
