Robot Autonomy for Surgery
Autonomous surgery involves having surgical tasks performed by a robot
operating under its own will, with partial or no human involvement. There are
several important advantages of automation in surgery, which include increasing
precision of care due to sub-millimeter robot control, real-time utilization of
biosignals for interventional care, improvements to surgical efficiency and
execution, and computer-aided guidance under various medical imaging and
sensing modalities. While these methods may displace some tasks of surgical
teams and individual surgeons, they also present new capabilities in
interventions that are too difficult or go beyond the skills of a human. In
this chapter, we provide an overview of robot autonomy in commercial use and in
research, and present some of the challenges faced in developing autonomous
surgical robots
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
From Concept to Market: Surgical Robot Development
Surgical robotics and supporting technologies have really become a prime example of modern applied
information technology infiltrating our everyday lives. The development of these systems spans across
four decades, and only the last few years brought the market value and saw the rising customer base
imagined already by the early developers. This chapter guides through the historical development of the
most important systems, and provide references and lessons learnt for current engineers facing similar
challenges. A special emphasis is put on system validation, assessment and clearance, as the most
commonly cited barrier hindering the wider deployment of a system
Recent Advancements in Augmented Reality for Robotic Applications: A Survey
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
Origins of Surgical Robotics: From Space to the Operating Room
The rapid development of telerobotic systems led to novel applications beyond the
nuclear and industrial domains. Medical telerobotics enabled surgeons to perform medical operations from remote places, far from their patient. Telesurgery systems allow great flexibility, improved performance in general, and support the creation of ideal surgical conditions. The first attempts to develop telesurgical systems borrowed the idea from space research, where the need of novel robots emerged for invasive treatment, even under extremesituations, such as weightlessness. Telesurgical instruments on Earth appeared following the same concept, aiming first for military, then onward for civilian applications. Today, more than 1.5 million patients are receiving telerobotic treatment annually, worldwide. As the surgical robotics domain grew from the initial concepts, it developed along three major concepts: telesurgery, cooperatively controlled robots and automated (image-guided) applications. These domains continue to develop into application specific systems with the goal of
reaching the specificity and versatility of conventional surgical instruments
UMIRobot: An Open-{Software, Hardware} Low-Cost Robotic Manipulator for Education
Robot teleoperation has been studied for the past 70 years and is relevant in
many contexts, such as in the handling of hazardous materials and telesurgery.
The COVID19 pandemic has rekindled interest in this topic, but the existing
robotic education kits fall short of being suitable for teleoperated robotic
manipulator learning. In addition, the global restrictions of motion motivated
large investments in online/hybrid education. In this work, a newly developed
robotics education kit and its ecosystem are presented which is used as the
backbone of an online/hybrid course in teleoperated robots. The students are
divided into teams. Each team designs, fabricates (3D printing and assembling),
and implements a control strategy for a master device and gripper. Coupling
those with the UMIRobot, provided as a kit, the students compete in a
teleoperation challenge. The kit is low cost (< 100USD), which allows
higher-learning institutions to provide one kit per student and they can learn
in a risk-free environment. As of now, 73 such kits have been assembled and
sent to course participants in eight countries. As major success stories, we
show an example of gripper and master designed for the proposed course. In
addition, we show a teleoperated task between Japan and Bangladesh executed by
course participants. Design files, videos, source code, and more information
are available at https://mmmarinho.github.io/UMIRobot/Comment: Accepted on IROS 2023, 8 page
Robot Control for Remote Ophthalmology and Pediatric Physical Rehabilitation
The development of a robotic slit-lamp for remote ophthalmology is the primary purpose of this work. In addition to novel mechanical designs and implementation, it was also a goal to develop a control system that was flexible enough to be adapted with minimal user adjustment to various styles and configurations of slit-lamps. The system was developed with intentions of commercialization, so common hardware was used for all components to minimize the costs. In order to improve performance using this low-cost hardware, investigations were made to attempt to achieve better performance by applying control theory algorithms in the system software. Ultimately, the controller was to be flexible enough to be applied to other areas of human-robot interaction including pediatric rehabilitation via the use of humanoid robotic aids. This application especially requires a robust controller to facilitate safe interaction. Though all of the prototypes were successfully developed and made to work sufficiently with the control hardware, the application of advanced control did not yield notable gains as was hoped. Further investigations were made attempting to alter the performance of the control system, but the components selected did not have the physical capabilities for improved response above the original software implemented. Despite this disappointment, numerous novel advances were made in the area of teleoperated ophthalmic technology and pediatric physical rehabilitation tools. This includes a system that is used to remote control a slit-lamp and lens for examinations and some laser procedures. Secondly, a series of of humanoid systems suitable for both medical research and therapeutic modeling were developed. This included a robotic face used as an interactive system for ophthalmic testing and training. It can also be used as one component in an interactive humanoid robotic system that includes hands and arms to allow use of teaching sign language, social skills or modeling occupational therapy tasks. Finally, a humanoid system is presented that can serve as a customized surrogate between a therapist and client to model physical therapy tasks in a realistic manner. These systems are all functional, safe and low-cost to allow for feasible implementation with patients in the near future
