The future of robotic surgery

© 2018 Royal College of Surgeons.For 20 years Intuitive Surgical’s da Vinci® system has held the monopoly in minimally invasive robotic surgery. Restrictive patenting, a well-developed marketing strategy and a high-quality product have protected the company’s leading market share.1 However, owing to the nuances of US patenting law, many of Intuitive Surgical’s earliest patents will be expiring in the next couple of years. With such a shift in backdrop, many of Intuitive Surgical’s competitors (from medical and industrial robotic backgrounds) have initiated robotic programmes – some of which are available for clinical use now. The next section of the review will focus on new and developing robotic systems in the field of minimally invasive surgery (Table 1), single-site surgery (Table 2), natural orifice transluminal endoscopic surgery (NOTES) and non-minimally invasive robotic systems (Table 3).Peer reviewedFinal Published versio

Nanorobotics in Medicine: A Systematic Review of Advances, Challenges, and Future Prospects

Nanorobotics offers an emerging frontier in biomedicine, holding the potential to revolutionize diagnostic and therapeutic applications through its unique capabilities in manipulating biological systems at the nanoscale. Following PRISMA guidelines, a comprehensive literature search was conducted using IEEE Xplore and PubMed databases, resulting in the identification and analysis of a total of 414 papers. The studies were filtered to include only those that addressed both nanorobotics and direct medical applications. Our analysis traces the technology's evolution, highlighting its growing prominence in medicine as evidenced by the increasing number of publications over time. Applications ranged from targeted drug delivery and single-cell manipulation to minimally invasive surgery and biosensing. Despite the promise, limitations such as biocompatibility, precise control, and ethical concerns were also identified. This review aims to offer a thorough overview of the state of nanorobotics in medicine, drawing attention to current challenges and opportunities, and providing directions for future research in this rapidly advancing field

Microdispositivos:: herramientas para aplicaciones médicas

Abstract: This article reviews the literature on the latest advances in microdevices for medical applications. The objective is to show an overview of the latest devices and their applications, as well as future development vectors in the area. A search of about 170 articles was performed, most of them published between the years 2015 and 2021, of which 53 were chosen as they were the most topical and impactful in the research fields referred to drug delivery, minimally invasive surgery, and cranial and vascular intromissions. It is concluded that, although microdevices are at an advanced stage of research, they still have many challenges to be solved, which has not allowed clinical trials to be completed in many cases. One of the great challenges ahead is to increase the precision in locomotion and to make the devices capable of performing more complex tasks with the help of smaller-scale electronic devices.Resumen: El presente artículo realiza una revisión de la literatura sobre los últimos avances en cuanto a los micro dispositivos para aplicaciones médicas. El objetivo es mostrar un panorama general de los últimos dispositivos y sus aplicaciones, así como los futuros vectores de desarrollo en el área. Se realizó una búsqueda de alrededor de 170 artículos, la mayoría de ellos publicados entre los años 2015 y 2021, de los cuales se eligieron 53 al ser los de mayor actualidad e impacto en los campos de investigación referidos a la administración de fármacos, la cirugía mínimamente invasiva, y las intromisiones craneales y vasculares. Se concluye que, si bien los micro dispositivos están en una etapa avanzada de investigación, aún tienen muchos desafíos por solucionar, lo cual no ha permitido completar en muchos casos las pruebas clínicas. Uno de los grandes desafíos futuros es incrementar la precisión en locomoción y conseguir que los dispositivos puedan realizar tareas más complejas con ayuda de dispositivos electrónicos de menor escala

Nanotechnology and medicine improvement

Nanotechnology has become an extraordinarily hopeful area in several human domains. Many scientific disciplines are developing their works in this area since the emergence of nanoscale, giving their contribution to the development of nanosciences. Many recent researches in areas as physical sciences, molecular engineering, biology, biotechnology and medicine for example are contributing for the investigation of biosystems at a nanoscale. Nanotechnology and nanobiosystems are becoming a privileged domain to reach an advanced level in the human development in many fields, as the examples of the biotechnology processes, the synthesis of new drugs and their delivery on a live body, the regenerative medicine and the new technologies in medicine (biotechnology and nanotechnology), body area networks for telemedicine (nanomedicine, nanoimaging, nanotechnological implants, in-body diagnostic systems, nanobiomedical wired devices, etc), or the application on the sustainability of the environment. Nanoscale may provide the tools to get improved conditions to investigate biosystems and to get advances with nanomaterials. These nanoscales, used in biosystems, contribute to enhance very innovative and promising results in medical area. Improvements in the telemedicine and on health are expectable with new systems operations and new nanotechniques.
