The invention relates to an endoscopic instrument (1) having an elongate body with a distal end (4) designed to be introduced into the body of the patient so as to come into proximity with an internal organ, the distal end carrying a tool (7) for intervention on the internal organ. The endoscopic instrument has a fool (10) rigidly connected to the distal end and designed to bear on the internal organ, and also controllable means (13) for conferring movements on the tool, at least in directions transverse to a longitudinal axis (X) of the distal end of the endoscopic instrument, when the foot is bearing against the internal organ.

A miniaturized scanning system to generate movement of a flexible device positioned at a distal part of a medical tool. The miniaturized scanning system includes an inner shaft with a longitudinal axis, adapted to guide said flexible device along the longitudinal axis, an abutment comprising an external surface and adapted to maintain said device, and a pusher mechanism adapted to engage with said abutment. The miniaturized scanning system includes at least one end portion adapted to contact said external surface of the abutment at a contact point, wherein said end portion is configured to translate along said longitudinal axis of the inner shaft and wherein the translation of said end portion results in a bending of the device in a bending plane defined by the longitudinal axis of the inner shaft and said contact point.

The ID2U project deals with the development of core technologies dedicated to the conception of a dexterous instrument for minimally invasive surgery. First, a prospective study on distal cinematic has been carried out. Then, flexible structures associated with fluidic actuators have been developed to build the distal tool. Finally, an ergonomic external mechanical structure has been proposed to achieve a whole new concept of surgical instrument. © 2011 Published by Elsevier Masson SAS.

This article presents work carried out as part of the robot sécurisé d'assistance à la chirurgie endoscopique (Rosace) project (funding ANR TecSan06), involving both academic and clinical partners along with an industrial partner in charge of technology integration. The main subject is a lightweight and compact robot for assistance in the endoscopic surgery field. The goal of the project has been to improve then transfer on a medical-grade product some technologies initially developed by the two academic partners. These technologies are: a first prototype of a robotic endoscope holder, an original method for visual servoing based on instrument tracking and some work done on comanipulation concept which consists in synergic interaction between robot and user. In accordance with the initial goals, major improvements have been obtained on these three aspects of the project. Robotic architecture improvement has contributed to enhance robot's versatility while robot command has been made more efficient and simple to use thanks to instrument tracking and comanipulation. After this 3-year project, initial prototype has turned into a commercially available product integrating (or that will integrate in a few months) these new technologies. © 2010 Elsevier Masson SAS.
