Seminar - Manipulating Tissue Using Magnetic Retraction in Minimal Access Surgery by Dr Yu-Sheng Lin
Date: 06 January 2016 (Wednesday)
Time: 11:00 am – 12:00 pm
Venue: EF305, The Hong Kong Polytechnic University
Nanoscale Iron-Oxide ferrofluid presents a special superparamagnetism while responses to an external magnetic field and there is induced an attraction force. The aim of this project was to investigate the use of ferrofluid to retract tissue and provide a protocol of use, in particular Minimal Invasive Surgery (MIS). The experimental method included a series of ex-vivo experiments with ferrofluids using the self-built device and in-vivo experiments conducted in a pig model via a laparotomy to measure the attraction and adhesion. The performance was presented by the retracted distance of raising bowel up to a desired distance for operation. This is a stage of proof of concept and the result has shown the potential to assist in tissue manipulation.
Dr. Yu-Sheng Lin was a research fellow in the Department of Mechanical and Aerospace Engineering at Queen’s University Belfast. He worked on instrumentation and mechanical design on several topics of applied science. His recent research was about establishing a testing method to carry a portable inspection of the thermoform polymers prior to the forming process. However, he is going to present his previous work on the alternative method of tissue manipulation for minimal access surgery. He received his Ph.D. in Mechanical Engineering from University of Leeds in the UK in 2014, M.S. in Aeronautics and Astronautics Engineering from National Cheng Kung University in Taiwan in 2008 and B.E. in Mechanical and Automation Engineering from I-Shou University in Taiwan in 2004.
