New 'i-Snake' will provide platform for next generation of robotic technology
4 January 2008
Minimally invasive - or so called 'keyhole' - surgery was one of the great medical advances of the 20th century, allowing sophisticated surgical operations to be carried out with little trauma. However, there are limits to the types of procedures that can be carried out this way. A new surgical robot to be developed, the 'i-Snake', aims to provide a platform to extend the use of this surgical technique, breaking new ground across the fields of surgery and engineering.
The i-Snake will incorporate state of the art imaging and intuitive manipulation technologies, allowing surgeons to carry out more complex and demanding procedures within the body, previously only possible using more invasive surgical approaches.
A world-renowned team from Imperial College London has been awarded over £2.1 million from the Wellcome Trust to develop the i-Snake over the next four years. The multidisciplinary research team includes Professor Lord Ara Darzi, one of the UK's leading surgeons in the field of minimum invasive surgery (MIS), and Professor Guang-Zhong Yang, Director of Medical Imaging and Robotics at the Institute of Biomedical Engineering.
Using special motors, multiple sensing mechanisms and imaging tools at its 'head', the flexible i-Snake robot will act as the surgeon's hands and eyes, allowing them to navigate difficult and restrictive regions of the body. Among the many possible applications of i-Snake are the clinical investigation of the alimentary tract, and complex, multi-vessel coronary bypass surgery.
Professor Lord Ara Darzi comments: "The unrivalled imaging and sensing capabilities coupled with the accessibility and sensitivity of i-Snake will enable more complex diagnostic and therapeutic procedures than are currently possible. The cost benefits that i-Snake will introduce include earlier, cheaper and less invasive treatment, faster recovery and procedure times and intangible benefits through an increase in patient care and quality of life."
Professor Guang-Zhong Yang said: "The i-Snake uses a biologically-inspired articulation design to allow flexible articulation of the instrument tip. It combines both intra- and interoperative image guided surgical navigation with dynamic active constraints for improved surgical precision and safety. The project represents a unique cross-disciplinary collaboration within Imperial College in imaging, sensing and robotics."
Dr Ted Bianco, Director of Technology Transfer at the Wellcome Trust, said: "Gone are the days when the surgeon's knife ruled in the operating theatre. The future of surgery is in smart devices like i-Snake".

Notes to editors
1. 'I-Snake' is an imaging-sensing navigated and kinematically enhanced (i-Snake) robot.
2. The Wellcome Trust is the largest charity in the UK. It funds innovative biomedical research, in the UK and internationally, spending around £500 million each year to support the brightest scientists with the best ideas. The Wellcome Trust supports public debate about biomedical research and its impact on health and wellbeing.
3. Professor the Lord Darzi of Denham KBE is the Parliamentary Under Secretary of State for the Lords at the Department of Health. In addition to his ministerial duties, Professor Lord Darzi maintains two full days of research and clinical activities at Imperial College, where he holds the Paul Hamlyn Chair of Surgery at Imperial College London, and he is an honorary consultant at St Mary's Hospital and The Royal Marsden.
Professor Lord Ara Darzi has pioneered many new techniques and technologies, including the first fully integrated surgical robotics systems in the UK the 'da Vinci System' - a teleoperative machine featuring wristed instruments with seven degrees of freedom, which has allowed surgeons to perform procedures with increased precision.
4. Rated as the world's fifth best university in the 2007 Times Higher Education Supplement University Rankings, Imperial College London is a science-based institution with a reputation for excellence in teaching and research that attracts over 12 000 students and 6000 staff of the highest international quality.
Innovative research at the College explores the interface between science, medicine, engineering and management and delivers practical solutions that improve quality of life and the environment - underpinned by a dynamic enterprise culture.
With 66 Fellows of the Royal Society among its current academic staff and distinguished past members of the College including 14 Nobel Laureates and two Fields Medallists, Imperial's contribution to society has been immense. Inventions and innovations include the discovery of penicillin, the development of holography and the foundations of fibre optics. This commitment to the application of its research for the benefit of all continues today with current focuses including interdisciplinary collaborations to tackle climate change and mathematical modelling to predict and control the spread of infectious diseases.
