The nanotechnology research space is rapidly growing, with vast implications for the healthcare, consumer electronics, surveillance, and defense industries. However, a major limitation to this research is the ability to create particles that vary in shape and function on a micrometer or nanometer scale. http://phys.org/news279986582.html Nanotechnology Wed, 13 Feb 2013 14:03:33 EST news279986582 Surgeries with the endoscope are exacting and require special capabilities of the surgeon. The suturing of the tissue and the setting of the knots, in particular, is very complicated due to the lack of space for movement. A new, minimally invasive suturing tool simplifies the procedure. In the future, the suture material will no longer be knotted, but welded with a laser. The device will be displayed at the MEDTEC Fair in Stuttgart, from March 22-24, 2011 http://phys.org/news218114533.html Medicine & Health Mon, 28 Feb 2011 11:23:12 EST news218114533 A comparison of two types of minimally invasive surgery to repair kidney blockages that prevent urine from draining normally to the bladder found that robot-assisted surgery was faster and resulted in less blood loss and shorter hospital stays. http://phys.org/news185943150.html Medicine & Health Sun, 21 Feb 2010 09:10:01 EST news185943150 This month Fox Chase Cancer Center performed the world's first successful minimally invasive distal pancreatectomy using the ViKY® system's revolutionary robotic, compact laparoscope holder. The technology, developed in France and tested on thousands of patients in Europe, made its debut in a cancer setting in the United States this week at Fox Chase. http://phys.org/news157127617.html Medicine & Health Tue, 24 Mar 2009 15:34:42 EST news157127617
