A Nebraska researcher has developed a robot that can be inserted into a patient's abdomen to give surgeons a new perspective during operations.
The robot, developed at the University of Nebraska Medical Center in Omaha, is designed to provide additional information for surgeons performing minimally invasive "keyhole" procedures.
The device can move around inside a patient's abdomen to give surgeons a new perspective on the area. The robot is also equipped with a retractable needle, allowing it to perform biopsies.
The device is 15 millimeters in diameter and can be inserted through the small incisions used in keyhole surgery. It consists of two rotating aluminum cylinders connected by an axle that carries the camera. The spiral pattern on the surface of the cylinders allows them to grip the walls of the abdominal cavity and move without slipping or damaging tissue.
Dmitry Oleynikov, who developed the device, will present his device during April's annual meeting of the Society of American Gastrointestinal and Endoscopic Surgeons in Dallas.

Surgery by satellite -- New possibilities at medicine's cutting edge
Robotic surgery may be coming to your town. Robots that perform surgery can be driven by surgeons who no longer stand by the patient, but direct the operation from a computer console. In most cases the surgeon is seated at a console within the theatre, only a few metres away from the patient. Now a team of surgeons and scientists have shown that the surgeon and robot can be linked via a 4,000 mile Internet connection, or by satellite, reported in the journal The International Journal of Medical Robotics and Computer Assisted Surgery.

Tufts to develop morphing 'chemical robots'
Tufts University has received federal funding to develop chemical robots that will be able to squeeze into spaces as tiny as 1 centimeter, then morph into something 10 times larger, and ultimately biodegrade. The "chembots" could access urban environments, tunnels, caves and debris fields, and carry out other risky operations in complex environments.
