Learn about Cotton Candy and Robotic Surgery Female: Engineered human tissue is an effective way to replace severely injured or burned skin. But it does have limitations samples are limited in size and often die due to lack of blood supply. The solution, cotton candy and know it is not for eating. Male: When I say about cotton candies again it is inexpensive, it is very rapid for using – it is a very rapid way for producing micro channel and micro fiber. It is also non-toxic so even though you certainly don’t want large size of sugar in the body it is not by far making thing out of arsenic that kind of thing. So they are fewer words about that so I think it is a very nice material. Female: The fibers in cotton mass are used like a mold upon which to make new skin. Male: If you take cotton candy which is why water soluble material it will disappear as base in water. And you pour this PDMS on top which is not water soluble especially when it is cured. Then as the water dissolves away the fibers, you basically get a bunch of micro channels wherever the fibers were in the network. So you can imagine sort of the inverse of cotton candy. Female: A biodegradable molding solution is poured over the candy. And when it set, the sugar is dissolved out leaving capillary like channels. Male: There is really no limit to what is type of tissue engineered tissue can be applied to. People who have loss of tissue either are a result of cancer, trauma, and congenital deficits will all benefit. From replacement parts that ultimately can be made in the lab. Female: Once the molded is set and the sugar dissolved out. Cells for blood vessels can be seated into the channels of the mold and skin old bone cells growing around them. The multitude of tiny channels should allow for extensive blood flow to the new tissue. Aiding the delivery of nutrients and the removal of waste as cells are repaired, the cotton candy idea has only been used in synthetic molds with rat’s cells thus far. But scientists have hopes that they can continue working with this simple inexpensive substance. Rather than swap to another material for human tissue. Like the sun says a spoonful of sugar helps the medicine go down. Thanks to Hollywood films like Terminator and to Transformers. People are a little bit weary of having robots rummaging round inside them. But according to Guy’s Hospital in London, robots are the surgeons and patient’s best friend. Robots provide the surgeon with an ultra-clear greatly magnified 3D view of the inside of your body. In this case a surgeon is removing a prostate cancer from a patient and he is not even in the same room. His movements are being relayed to the robot who executes the maneuvers with unparallel precision. Not a human like trainer in sight because the image appear larger to the surgeon. He is free to make larger gestures which of course the robot translates back to micro maneuvers. Male: The 3D is fantastic it is like you are inside of the patient. It really feels like you are actually inside, seeing everything and because of that you can move much more intuitively. You can move just like you would with not normal surgery. Female: For the patient, the risk of damage to neighboring tissue and organs is minimized. Entry incisions are kept to a minimum making recovery less of an ordeal. In fact 24 hours after having his prostate cancer removed this patient is packing his bags and heading home. The first surgical robot was called ISOP the latest is called the Cyber Knife which delivers radio therapy to tumors with pinpoint accuracy.
