    Full text link
    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

    elemedicine provides a transformative practice for access to and delivery of timely and high quality healthcare in resource-poor settings. In a typical scenario of telesurgery, surgical tasks are performed with one surgeon situated at the patient’s side and one expert surgeon from a remote site. In order to make telesurgery practice realistic and secure, reliable transmission of medical videos over large distances is essential. However, telesurgery videos that are communicated remotely in real time are vulnerable to distortions in signals due to data compression and transmission. Depending on the system and its applications, visual content received by the surgeons differs in perceived quality, which may incur implications for the performance of telesurgery tasks. To rigorously study the assessment of the quality of telesurgery videos, we performed both qualitative and quantitative research, consisting of semi-structured interviews and video quality scoring with human subjects. Statistical analyses are conducted and results show that compression artifacts and transmission errors significantly affect the perceived quality; and the effects tend to depend on the specific surgical procedure, visual content, frame rate, and the degree of distortion. The findings of the study are readily applicable to improving telesurgery systems

    Healthcare 5.0 is a system that can be deployed to provide various healthcare services. It does these services by utilising a new generation of information technologies, such as Internet of Things (IoT), Artificial Intelligence (AI), Big data analytics, blockchain and cloud computing. Due to the introduction of healthcare 5.0, the paradigm has been now changed. It is disease-centered to patient-centered care where it provides healthcare services and supports to the people. However, there are several security issues and challenges in healthcare 5.0 which may cause the leakage or alteration of sensitive healthcare data. This demands that we need a robust framework in order to secure the data of healthcare 5.0, which can facilitate different security related procedures like authentication, access control, key management and intrusion detection. Therefore, in this review article, we propose the design of a secure generalized healthcare 5.0 framework. The details of various applications of healthcare 5.0 along with the security requirements and threat model of healthcare 5.0 are provided. Next, we discuss about the existing security mechanisms in healthcare 5.0 along with their performance comparison. Some future research directions are finally discussed for the researchers working in healthcare 5.0 domain

    Background: The surgical telementoring is a technology that involves surgical procedures guided by an expert or mentor, performed by other surgeons from a distance, using information and knowledge technologies. This therapeutic innovation has generated new opportunities to improve the surgical attention and the training of the surgeons. However, their ethical implications should be analyzed to clarify their use, to check the patient's safety and eliminate uncertainties. The characteristics of surgical telementoring generate specific challenges and ethical dilemmas that must be identified, analyzed and solved. Results: In this paper the ethical challenges and dilemmas of surgical telementoring identified and analyzed cover multiple aspects such as patient safety, privacy and vulnerability, the surgeon-mentor-patient relationship and informed consent, professional responsibility, cost-effectiveness analysis and Solidarity and social justice regarding the use of healthcare resources, the systematic approach to validation of the proposed new technology and conflicts of interest. For many of these issues solutions are provided, but they are still to be solved. Conclusions: surgical telementoring potentially improves patient healing and surgeon education. It will have a rapid evolution in the next years. This rapid growth should not be anticipated to the solid implantation of ethical guarantees for its use due to the particular characteristics that this technology has in the field of telemedicine.Antecedentes: El uso de tele-tutoría en cirugía es una tecnología que incluye procedimientos quirúrgicos guiados por un experto o tutor, realizado por otros cirujanos a distancia usando tecnologías de información y conocimiento.

    Two healthcare domain related programs in which this author has curricular relationships are the undergraduate Diagnostic Ultrasound (DU), and the graduate Master of Science in Health Informatics (MSHI). He teaches one course in the former and is the program coordinator for the latter. The undergraduate course is titled, “Computers in Medicine”, and is a rough 50% combination of a first-semester computing hardware course taught to our IT undergrads and another 50% of material from a textbook covering all the ways in which computing has benefitted various healthcare domains like, surgery, pharmacy, imaging, dentistry, psychiatry, remote medicine and the like. The MSHI program is a 30 semester credit hour program offered in an online format with a capstone experience (no thesis required) that was designed for professionals expecting to retool themselves for continued employment in a healthcare setting. This paper will discuss the details of the DU course and the MSHI program, the kind of computing content covered in each, and the rationale for and program design input of each. In conclusion, the reader will be left with an understanding of the what, when, how and why computing topics are necessarily required by these curricula, our justification for such, and how we might use that information in the development of future healthcare-related computing courses and potential programs. Course definition and program outline documents will be attached as appendices to the paper
