    © 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

    Assumptions Advanced MIS procedures in neonates & infants <5 kg are a very demanding field because of: • very small anatomical structures • limited operative spaces (5-7 cm3) Postulate 3D laparoscopy improves operative time & precision in small spaces Advantages in 3D laparoscopy are mostly described in adults for better depth perception, more precise visualization of anatomical structures, as well as for complex manoeuvres such as suturing. In the pediatric field these data are lacking. In collaboration with Neuromed (Neuromed Spa, Torino) and Storz (Karl Storz, Tuttlingen, Germany) we tested 3D 4mm scopes specific for pediatric laparoscopy with a 3D HD camera, with the possibility to shift from 3D to 2D. In vitro setting – 1 With Visionsense III Stereoscopic Endoscopy System (Neuromed Spa), FDA and CE approved for pediatric surgery, we performed a comparative study between surgical skills achievements in subjects without any surgical experience, using 2D and a 3D laparoscopic equipment. 3 skills were evaluated in 2D and 3D modalities. 20 pediatrics residents without any previous laparoscopic experience were randomly divided in two groups and evaluated doing object transfer and basic surgical manoeuvres in a laparoscopic simulator validated for pediatric surgery. Switching the type of vision from 2D to 3D we evaluated bimanual dexterity, efficiency, tissue handling in both modalities. Time and error rates (missed attempts, dropped objects, and failure to complete the task) were recorded. In vitro setting – 2 Experimental project comparing 2D vs 3D laparoscopic camera in a set-up standardized and validated for Pediatric Surgeons. With Storz TipCam 4mm, we performed a comparative study between surgical skills achievements in experienced pediatric surgeons. Four skills were evaluated in 2D and 3D modalities. 10 pediatric surgeons with more than 50 MIS procedures were randomly divided in two groups and evaluated doing 3 training modules (“threading”, “suturing”, “tension suturing” and “intestinal anastomosis”) in a laparoscopic simulator (iSIM2 – iSurgicals, Chorley, UK). Switching the type of vision from 2D to 3D we evaluated bimanual dexterity, efficiency, tissue handling in both modalities. Time and error rates (missed attempts and failure to complete the task) were recorded. Inconveniences related to the 3D vision were also recorded. Surgical Application Using Visionsense III Stereoscopic Endoscopy System and Storz TipCam 4mm we performed 40 laparoscopic/thoracoscopic procedures in children and neonates hospitalized at the Regina Margherita Children’s Hospital. Operative time and intra- or post-operative complications were recorded

    Augmented reality (AR) for surgical robotic and autonomous systems: State of the art, challenges, and solutions

    Get PDF
    Despite the substantial progress achieved in the development and integration of augmented reality (AR) in surgical robotic and autonomous systems (RAS), the center of focus in most devices remains on improving end-effector dexterity and precision, as well as improved access to minimally invasive surgeries. This paper aims to provide a systematic review of different types of state-of-the-art surgical robotic platforms while identifying areas for technological improvement. We associate specific control features, such as haptic feedback, sensory stimuli, and human-robot collaboration, with AR technology to perform complex surgical interventions for increased user perception of the augmented world. Current researchers in the field have, for long, faced innumerable issues with low accuracy in tool placement around complex trajectories, pose estimation, and difficulty in depth perception during two-dimensional medical imaging. A number of robots described in this review, such as Novarad and SpineAssist, are analyzed in terms of their hardware features, computer vision systems (such as deep learning algorithms), and the clinical relevance of the literature. We attempt to outline the shortcomings in current optimization algorithms for surgical robots (such as YOLO and LTSM) whilst providing mitigating solutions to internal tool-to-organ collision detection and image reconstruction. The accuracy of results in robot end-effector collisions and reduced occlusion remain promising within the scope of our research, validating the propositions made for the surgical clearance of ever-expanding AR technology in the future

    Robots are expanding from industrial applications to daily life, in areas such as medical robotics, rehabilitative robotics, social robotics, and mobile/aerial robotics systems. In recent years, augmented reality (AR) has been integrated into many robotic applications, including medical, industrial, human–robot interactions, and collaboration scenarios. In this work, AR for both medical and industrial robot applications is reviewed and summarized. For medical robot applications, we investigated the integration of AR in (1) preoperative and surgical task planning; (2) image-guided robotic surgery; (3) surgical training and simulation; and (4) telesurgery. AR for industrial scenarios is reviewed in (1) human–robot interactions and collaborations; (2) path planning and task allocation; (3) training and simulation; and (4) teleoperation control/assistance. In addition, the limitations and challenges are discussed. Overall, this article serves as a valuable resource for working in the field of AR and robotic research, offering insights into the recent state of the art and prospects for improvement

    Methods and Tools for Objective Assessment of Psychomotor Skills in Laparoscopic Surgery

    Get PDF
    Training and assessment paradigms for laparoscopic surgical skills are evolving from traditional mentor–trainee tutorship towards structured, more objective and safer programs. Accreditation of surgeons requires reaching a consensus on metrics and tasks used to assess surgeons’ psychomotor skills. Ongoing development of tracking systems and software solutions has allowed for the expansion of novel training and assessment means in laparoscopy. The current challenge is to adapt and include these systems within training programs, and to exploit their possibilities for evaluation purposes. This paper describes the state of the art in research on measuring and assessing psychomotor laparoscopic skills. It gives an overview on tracking systems as well as on metrics and advanced statistical and machine learning techniques employed for evaluation purposes. The later ones have a potential to be used as an aid in deciding on the surgical competence level, which is an important aspect when accreditation of the surgeons in particular, and patient safety in general, are considered. The prospective of these methods and tools make them complementary means for surgical assessment of motor skills, especially in the early stages of training. Successful examples such as the Fundamentals of Laparoscopic Surgery should help drive a paradigm change to structured curricula based on objective parameters. These may improve the accreditation of new surgeons, as well as optimize their already overloaded training schedules

    Kidney targeting and puncturing during percutaneous nephrolithotomy: recent advances and future perspectives

    Get PDF
    Background and Purpose: Precise needle puncture of the kidney is a challenging and essential step for successful percutaneous nephrolithotomy (PCNL). Many devices and surgical techniques have been developed to easily achieve suitable renal access. This article presents a critical review to address the methodologies and techniques for conducting kidney targeting and the puncture step during PCNL. Based on this study, research paths are also provided for PCNL procedure improvement. METHODS: Most relevant works concerning PCNL puncture were identified by a search of Medline/PubMed, ISI Web of Science, and Scopus databases from 2007 to December 2012. Two authors independently reviewed the studies. RESULTS: A total of 911 abstracts and 346 full-text articles were assessed and discussed; 52 were included in this review as a summary of the main contributions to kidney targeting and puncturing. CONCLUSIONS: Multiple paths and technologic advances have been proposed in the field of urology and minimally invasive surgery to improve PCNL puncture. The most relevant contributions, however, have been provided by the application of medical imaging guidance, new surgical tools, motion tracking systems, robotics, and image processing and computer graphics. Despite the multiple research paths for PCNL puncture guidance, no widely acceptable solution has yet been reached, and it remains an active and challenging research field. Future developments should focus on real-time methods, robust and accurate algorithms, and radiation free imaging techniques.The authors acknowledge Foundation for Science and Technology (FCT) for the fellowships references: SFRH/BPD/46851/2008 and SFRH/BD/74276/2010

    Tell me your story: digital storytelling as a teaching and communication tool

    Get PDF
    The paper describes an exploratory study focused on the use of Digital Storytelling (DS) as a tool for design students to communicate their self-reflection process and reveal their soft skills to a future employer. Digital Storytelling is widely recognised in the literature, as an innovative learning strategy supported by practical cases with implementation in classrooms. Based on the premise that DS can be used as a vehicle to help students “think about your own identity”, the creative process of finding students’ narratives led them to reflect on themselves and their life experiences. This study aimed to help students to reflect on their own cognitive profile during problem design solving and communicate creatively their soft skills to a future employer using a digital narrative. Product design students worked on their narratives for four weeks in practical classes during a course concerned with visual communication techniques. Students used digital technologies and computer software to create an individual short videos and communicate autobiographical narratives with original images and audio where the narrator is the story’s protagonist. The stories were visualized in a group session with an invited DS specialist and a focus group was held to find out teachers' perceptions about the suitability of the DS as a tool for students' self-reflection. As an outcome, students' narratives focused on remarkable personal life experiences or academic involvements, some of them showing a significant emotional charge, others trying to highlight singular characteristics which may be appreciated and valued by a future employer.publishe
