Patent number: 8920433Abstract: A manipulator includes a control unit (1), with handle (4) and control buttons (4a-4d), and a connecting arm (2) which, at its proximal end (2a), carries the control unit (1) and, at its distal end (2b), carries a work unit (3). The control buttons (4a-4d) control at least a first inclination motor, which causes a movement of inclination of a tool support (5) of the work unit (3) about a transverse inclination axis (11), and they control the actual rotation of the tool support (5) about its direction of inclination (II) and control the orientation of the direction of inclination (II) about the longitudinal axis (I-I) of the connecting arm (2). A particularly ergonomic manipulator is thus obtained which is easy to learn to use and which efficiently separates the stresses arising from movements of the tool support (5) and the stresses arising from holding and moving the manipulator itself.Type: GrantFiled: July 30, 2010Date of Patent: December 30, 2014Assignee: Dexterite SurgicalInventors: Pascal Barrier, Jérémy Ollagnier, Rémi Rosset-Lanchet, Christine Melennec épouse Barthod, Max Giordano

Patent number: 8821512Abstract: A manipulator includes a control unit (1), with handle (4) and control buttons (4a-4d), and a connecting arm (2) which, at its proximal end (2a), carries the control unit (1) and, at its distal end (2b), carries a work unit (3). The handle (4) is articulated about at least one transverse articulation axis (4e), which is itself situated at an intermediate position along the handle (4). A particularly ergonomic manipulator is thus obtained which is easy to learn to use and which efficiently separates the stresses arising from movements of the tool support (5) and the stresses arising from holding and moving the manipulator itself.Type: GrantFiled: July 30, 2010Date of Patent: September 2, 2014Assignee: Dexterite SurgicalInventors: Pascal Barrier, Jérémy Ollagnier, Rémi Rosset-Lanchet

Patent number: 8696651Abstract: A manipulator includes a main arm, of which the proximal end bears a drive, and a proximal manipulation structure, and of which the distal end bears a controlled distal structure that may itself bear a surgical tool. The main arm passes through a surgical trocar. The proximal manipulation structure includes two opposed contact zones and stress sensors positioned in a central zone between the two opposed contact zones. The stress sensors operate the drive as a function of the stresses applied to the contact zones in order to produce the pivoting and rotating movements of the surgical tool with respect to the main arm. This ensures that there is optimal decoupling of the movements in the various degrees of freedom, thus making it easier to obtain movements through stressing operations that are natural to the operating surgeon.Type: GrantFiled: January 31, 2009Date of Patent: April 15, 2014Assignee: Dexterite SurgicalInventors: Pascal Barrier, Jérémy Ollagnier, Gérard Gautier

Patent number: 8613740Abstract: A hand-held manipulator includes a handle (4) fixedly mounted on the end of a connecting arm (2), the distal end (2b) of which carries a work unit (3). The handle (4) includes a grip section (4e) having a surface of revolution about a longitudinal handle axis (III), which is aligned with the longitudinal axis (I) of the arm. Control elements (4a-4c) are shaped in an annular structure near the distal end (4f) of the grip section (4e) so as to be accessible in any angular orientation of the hand holding the handle.Type: GrantFiled: July 30, 2010Date of Patent: December 24, 2013Assignee: Dexterite SurgicalInventors: Pascal Barrier, Jérémy Ollagnier, Rémi Rosset-Lanchet
