Publication number: 20220296803Abstract: The disclosure relates to a surgical device comprising a rod having a deformable sleeve at its distal end surrounding the rod, the control element being longitudinally movable for moving the proximal end of the sleeve between a rest position, in which the deformable sleeve has a tubular shape, and an active position, in which the sleeve is deformed by bringing together its distal and proximal ends. The rod is made up of an internal hollow tubular element surrounded by a sheath that can move in translation and rotation relative to the internal hollow tubular element. The distal end of the sleeve is fixed onto a peripheral strip of the internal hollow tubular element and the proximal end of the sleeve is fixed onto a peripheral strip of the sheath.Type: ApplicationFiled: August 31, 2020Publication date: September 22, 2022Applicants: INSTITUT HOSPITALO-UNIVERSITAIRE DE CHIRURGIE MINI-INVASIVE GUIDEE PAR L'IMAGE, INSTITUT DE RECHERCHE CONTRE LES CANCERS DE L'APPAREIL DIGESTIF IRCADInventors: Joël LEROY, Amilcar ALZAGA

Publication number: 20210128154Abstract: The disclosure relates to a surgical staple defining a median folding zone which is continued by a pair of branches, each branch having a pointed fastening end and an intermediate clamping zone situated between the median folding zone and the pointed fastening end. The staple is deformable so that each branch can be folded relative to the median folding zone by causing each fastening end to approach the other branch, the staple being formed by a metal cutout pre-shaped by folding, and is of constant thickness. Intermediate clamping zones of the two branches are cut out such as to form at least two teeth, the edges of which form two complementary clamping surfaces, parallel to the median plane when the staple is folded. The cross-section of clamping surfaces correspond to the cross-section of the metal cutout.Type: ApplicationFiled: January 3, 2018Publication date: May 6, 2021Applicant: INSTITUT HOSPITALO-UNIVERSITAIRE DE CHIRURGIE MINI-INVASIVE GUIDEE PAR L'IMAGEInventors: Amilcar ALZAGA, Peter HALVAX, Lee L.

Patent number: 10736497Abstract: A method and a system for anatomical site relocalisation using dual data synchronisation. Method for repositioning, possibly several times, at a specific location, which has been already explored during a first or “reference exploration”, a flexible endoscope during one or more successive endoluminal or extraluminal subsequent or “new exploration”, or similar procedures, wherein the repositioning is realized either manually, by a human user, or automatically, by a robotic system, from or by way of a synchronisation process between a “new exploration” flexible endoscope video and the “reference exploration” flexible endoscope video displayed in parallel on or in two different windows, on one or more screens.Type: GrantFiled: March 11, 2014Date of Patent: August 11, 2020Assignees: INSTITUT HOSPITALO-UNIVERSITAIRE DE CHIRURGIE MINI-INVASIVE GUIDEE PAR L'IMAGE, INSTITUT DE RECHECHE SUR LES CANCERS DE L'APPAREIL DIGESTIF—IRCADInventors: Stephane Nicolau, Anant Suraj Vemuri, Luc Soler, Jacques Marescaux
