Abstract
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.
