A master interface device for remotely controlling at least one instrument mounted in an endoscope. The device includes at least one control handle device in the form of a subassembly able to be manipulated in the same degrees of freedom as the associated control instrument. The control device includes on the one hand a gripping and manoeuvring shaft, designed for gripping with the whole hand by the operator, and on the other hand a mounting bracket supporting said shaft. Translation and pivoting of the bracket controls respectively translation and rotation around itself of the associated instrument, and the pivoting of the shaft relative to the bracket controls the bending of the end of the instrument concerned.

Master interface device for a motorised endoscopic system and installation comprising such a device

A motorized, modular instrumentation device and an endoscopy system including such device. The motorized, modular instrumentation device includes at least one operational unit mounted on at least one support structure and integrating a motorized medical instrument module including, first, an elongated medical instrument with a tool arranged on one distal end, it being possible to bend the corresponding end portion of the instrument, and second, at least one electrical actuating element controlling the operation of the tool and/or the bending of the distal end portion, via transmission elements extending within the elongated body of the instrument. The actuating element(s) is/are installed in a hollow body connected to the proximal end of the instrument and the hollow body is itself arranged, with rotational guiding, within a reception housing adapted to move, at least translationally, on the support structure, the movements of the hollow body and the reception housing being motorized.

Motorised and modular instrumentation device and endoscopy system comprising such a device

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.
