Abstract: A control interface (I) for a robotic system for the vitreoretinal surgery includes a haptic device (1) equipped with an articulated chain (2) having a free end (3). The interface includes a guiding device (10). The guiding device (10) includes a stationary surface (11), a guiding (20) mounted on the stationary surface by a ball joint (21), and a rod (30) mounted on the guide (20) by a sliding connection (25) with an axis corresponding to that of the rod (30). The rod includes a first end (32) mounted stationary on the free end (3) of the haptic device (1) and a second end (33) on which a gripping member (5) is mountable.

Abstract: A control unit for a surgical device, said surgical device (2) comprising: at least one surgical tool comprising an end, called distal, adapted to come into contact with a patient (5), and adapted to be positioned in the patient (5), at least one robotic mobile element (7) on which the surgical tool is mounted, the robotic mobile element (7) being adapted to move said surgical tool, at least one depth imaging tool (8) adapted to acquire a depth image (22) at an acquisition area on the patient (5), said imaging tool (8) being adapted to move the acquisition area on the patient (5), said control unit (1) being adapted to send information to the at least one robotic mobile element (7) and/or the imaging tool (8) so that the position of the acquisition area substantially coincides with the position of the distal end of the surgical tool.

Abstract: An actuation mechanism for a surgical instrument (100) includes a sleeve (202) configured to receive the surgical instrument and including one or more parts (208, 210, 226), with studs (250, 252) provided on each part, on some parts only, or distributed over the different parts. At least two wheels (204, 206) are mounted on the sleeve on either side of the part or parts, each wheel being equipped with at least one groove (242) and a mechanical transmission element (244). The groove of each wheel movably receives one of the studs in the groove. At least two drive shafts (212, 214), each being equipped with a first mechanical transmission element (254), cooperate with the mechanical transmission element (244) of one of the wheels.
