Prevalence of haptic feedback in robot-mediated surgery : a systematic review of literature

© 2017 Springer-Verlag. This is a post-peer-review, pre-copyedit version of an article published in Journal of Robotic Surgery. The final authenticated version is available online at: https://doi.org/10.1007/s11701-017-0763-4With the successful uptake and inclusion of robotic systems in minimally invasive surgery and with the increasing application of robotic surgery (RS) in numerous surgical specialities worldwide, there is now a need to develop and enhance the technology further. One such improvement is the implementation and amalgamation of haptic feedback technology into RS which will permit the operating surgeon on the console to receive haptic information on the type of tissue being operated on. The main advantage of using this is to allow the operating surgeon to feel and control the amount of force applied to different tissues during surgery thus minimising the risk of tissue damage due to both the direct and indirect effects of excessive tissue force or tension being applied during RS. We performed a two-rater systematic review to identify the latest developments and potential avenues of improving technology in the application and implementation of haptic feedback technology to the operating surgeon on the console during RS. This review provides a summary of technological enhancements in RS, considering different stages of work, from proof of concept to cadaver tissue testing, surgery in animals, and finally real implementation in surgical practice. We identify that at the time of this review, while there is a unanimous agreement regarding need for haptic and tactile feedback, there are no solutions or products available that address this need. There is a scope and need for new developments in haptic augmentation for robot-mediated surgery with the aim of improving patient care and robotic surgical technology further.Peer reviewe

Intégration sur silicium et caractérisation de films minces de polyuréthane nanocomposite pour le développement de micro-actionneurs MEMS électrostrictifs

Ce travail de thèse s'inscrit dans le cadre général du développement de micro-actionneurs MEMS, à bas coût et de technologie simple, pour de futures applications dans le domaine de la microfluidique, notamment. La motivation de ce travail est d'évaluer la faisabilité d'un micro-actionneur électrostricitf à base de film mince polymère électroactif nanocomposite. Le polyuréthane, chargé en nanoparticules de carbone ou carbure de fer, encore peu étudié mais aux propriétés électrostrictives prometteuses, est choisi comme matériau à intégrer dans une filière MEMS silicium classique. Le premier chapitre dresse un état de l'art sur les actionneurs MEMS, présente les différentes familles de polymères électroactifs et définit ce qu'est l'électrostriction. Le second chapitre est consacré à l'intégration sur silicium de films minces de polyuréthane et au développement de différentes structures de tests. L'accent est mis sur la levée de plusieurs verrous technologiques. Le chapitre trois présente les méthodes de caractérisations mécaniques et électriques et les résultats obtenus sur films purs et nanocomposites. Le quatrième et dernier chapitre concerne la réalisation et la caractérisation de premiers démonstrateurs MEMS. Ces micro-actionneurs sont caractérisés de manière statique et dynamique.This thesis is part of the general development of MEMS microactuators, low cost and simple technology for future applications in the domain of microfluidics. The motivation of this work is to evaluate the feasibility of an electrostrictive microactuator based on electroactive nanocomposite polymer thin films. Polyurethane, loaded with carbon or iron carbide nanoparticles is chosen to be integrated in a conventional silicon MEMS process. The first chapter provides a state of the art of MEMS actuators, presents the different families of electroactive polymers and defines what is electrostriction. The second chapter is devoted to the integration of polyurethane thin films on silicon and to the development of different mechanical and electrical test structures. The emphasis is on identifying and overcoming technological barriers. Chapter three presents the mechanical and electrical characterization methods and the obtained results for pure and nanocomposites films. The fourth and final chapter concerns the realization and the static and dynamic characterizations of first MEMS demonstrators.VILLEURBANNE-DOC'INSA-Bib. elec. (692669901) / SudocSudocFranceF
