摘要:
A device for supporting and controlling the translational movement of an elongated body, the body extending along the longitudinal axis thereof in the form of a rod, such as a needle intended for a percutaneous medical procedure. The device is designed to be mounted to a support that can be controlled in terms of position and orientation, and includes: (i) a first member for gripping the body, whose movement can be controlled in the translation direction with a pre-determined maximum stroke; and (ii) a second fixed member which can guide the elongated body when the body is moved by the first mobile gripping member and which can maintain the body in position when the body is not engaged with the first member.

摘要:
Robotized installation for the guided and controlled positioning and movement of a component or an instrument for diagnostic or surgical treatment at or around the head of a patient, whereby the installation includes a robotic device that forms a serial kinematic chain and carries component or instrument at its free and position-controlled end. The robotic device has three kinematic sub-assemblies that are mutually combined in series and include, a first sub-assembly in the form of a rotary-articulation mechanism corresponding to a serial-type, spherical kinematic arrangement with three degrees of freedom, a second sub-assembly in the form of a mechanism with linear translation along an axis, and a third sub-assembly in the form of a second rotary-articulation mechanism, integral with the moving part of the second sub-assembly and also corresponding to a serial-type spherical kinematic arrangement with three degrees of freedom.

摘要:
A flexible endoscope device includes an elongated flexible body having an end segment bearing or defining the endoscope head, and provided with an optical system that can be curved or bent in at least two mutually perpendicular directions, the elongated body being functionally connected at the other end thereof to a control element capable of controlling at least the movements and/or the arrangement of the end segment. The device includes automatic flexion and positioning elements of the end segment by visual control, the elements essentially including a video processing element for receiving the images or video signals provided by the optical system of the endoscope head using a computer element capable of carrying out visual control operations on the basis of the processed video signals and of transmitting control signals, and actuation members that are part of or associated with the control elements.
摘要:
A device for controlled translational displacement of an elongated element that terminates in a frontal functional end, in particular an instrument/tool that is designed to be brought to an internal site in a patient, more particularly an exploratory instrument/surgical tool placed in a catheter or in an operating channel or working channel of a flexible endoscope, whereby the device includes a linear actuator that acts at the rear end of the elongated element that is located opposite its frontal functional end. The device that is characterized in that the actuator includes of a direct-drive electromagnetic linear motor with a shaft that moves in translation relative to a stator and that drives the elongated element, whereby the shaft can also be coupled to a rotary motor.
