#Mini robot space surgeon to climb inside astronauts It could one day answer the prayers of astronauts who need surgery in deep space.
The miniature surgeon slides into the body through an incision in the belly button. Once inside the abdominal cavity which has been filled with inert gas to make room for it to work the robot can remove an ailing appendix, cut pieces from a diseased colon or repair a perforated gastric ulcer.
The feed relays to a control station, where a human surgeon operates it using joysticks.

or 100 iterations. et surgeons credit the genetically enhanced pigs with some recent successes. Muhammad Mohiuddin,
a transplant surgeon and researcher at the National Heart, Lung, and Blood Institute, in Bethesda, Maryland, says a heart from one of Revivicor pigs lasted two and a half years inside a baboon.
That is because surgeons still need to completely replace a baboon heart with one from these pigs
but lungs are very difficult. ransplant surgeons say one of the largest obstacles they face is the immense cost of carrying out xenotransplant experiments.
#Transplant Surgeons Revive Hearts After Death Transplant surgeons have started using a device that allows them to eanimatehearts from people who have died recently,
In at least 15 cases, surgeons in the United kingdom and Australia say they have used the system to successfully transplant hearts removed from patients after theye died.
surgeons at St vincent Hospital in New south wales described three cases in which they waited as little as two minutes after a person heart stopped before they began removing it.
Without such help, surgeons consider hearts from dead donors too damaged to use. he device is vital.
says Stephen Large, a surgeon at Papworth Hospital in the United kingdom, which has used the system as part of eight heart transplants.
Transplant surgeons recognize two major categories of death. People can be brain dead, or they die

But surgeons found that hearts that stop naturally often didn start again, or can pump blood,
says Large, the Papworth surgeon. The crisis is particularly severe in the U k, . where handguns and some other firearms are prohibited,
the ethical dilemma is how long surgeons should wait before swooping in to retrieve organs. In the U s.,the accepted standard is five minutes,
although Colorado surgeons in 2008 took hearts from brain-damaged newborns after waiting only 75 seconds.
#Bionic eye implant world first Surgeons in Manchester have performed the first bionic eye implant in a patient with the most common cause of sight loss in the developed world.
and was led by Paulo Stanga, consultant ophthalmologist and vitreo-retinal surgeon at Manchester Royal Eye Hospital and professor of ophthalmology and retinal regeneration at the University of Manchester.
Surgeons at Manchester Royal Eye Hospital implanted a chip at the back of Mr Flynn eye in a four-hour procedure last month.
Surgeons will now insert the Argus II retinal implant into more patients over the coming months to demonstrate that it can work for a variety of patients.
