A device for assisting surgery includes means for offsetting a rotation of a first type and a second type, a mechanism for transmitting a rotation of a third type, and a mechanism for transforming the rotation of a third type into a translation. An elastic element is connected at one end to the mechanism for transmitting the rotation of a third type. The mechanism for transmitting the rotation of a third type is connected to a rotary motor, the rotation of the motor in a first direction causing the lowering of a tool and an elongation of the elastic element, the rotation of the motor in a second direction causing the raising of the tool and a contraction of the elastic element, and, when the tool is lowered and the rotary motor is not exerting any torque, the elastic element returns to an initial shape causing the raising of the tool.

Surgery-assistance device

A hand intended to equip a humanoid robot, the hand includes a palm and at least one finger extending along a first axis, the hand being capable of picking up an object, the finger comprising a first phalanx linked to the palm by a first motorized pivot link and a second phalanx consecutive to the first phalanx linked to the first phalanx by a second pivot link. The finger comprises a first mechanism linking the palm to the second phalanx configured such that the rotation of the first phalanx about the second axis causes the second phalanx to rotate about the third axis, and a second mechanism linking the palm to each of the phalanges configured to actuate the finger in such a way that the finger wraps around the object to be picked up, and the second mechanism is configured to deform the first mechanism.

Hand intended to equip a humanoid robot

A system is provided. The system includes a C-arm with an X-ray source and an X-ray detector mounted thereon opposite each other. The system also includes a carrier coupled to the C-arm and configured to rotate the C-arm relative to the carrier. The system further includes a base and a multiple robotic arms coupling the carrier to the base. Each robotic arm of the multiple robotic arms includes two articulated segments and at least two rotary joints.
