Here is an article on an idea that definitely raises the ick factor for surgery to a new level. Like something out of Stephen King's Creepshow, robotic cockroaches are being developed which can crawl into patients' bodies and remove diseased organs by dragging them back out through the mouth. This next step in robotic surgery is being developed by one of Britain's top doctors.
In the report titled, Robot insects to remove organs via patients' mouths,Sophie Goodchild, Health and Social Affairs Correspondent for the Standard, states "Keyhole surgery pioneer Lord Darzi is developing the "bug-bots", which are set to revolutionize scar-free surgery."
The insect bots would enter the patient's body via the mouth and be able to remove tumors or diseased organs by use of a laser. Then the surgeons can withdraw the surgical bots and diseased parts through the mouth. So, there would be no scarring on the patient's body. (I am not sure about the patient's mind!!!)
Seriously, this has great promise for surgery. Its not just the lack of scarring, it is the fact that this could reach tumors in difficult to reach areas and the patient's should recover much faster. Of course, you would have to get use to little robotic creatures crawling around your insides.
