Robot probe abdomen people

Researchers at the University of Nebraska have successfully created a robotic robot that can move inside the human abdomen, allowing the doctor to see where the surgery is going.

In addition, the robot is equipped with a needle for biopsy.

The robot consists of two rotating aluminum tubes, connected by a thick shaft. This shaft contains the camera. Spiral on the surface of the tube helps the robot cling to the abdominal wall and move around without damaging the tissue.

The robot is only 15mm in diameter. Thus, it can be inserted into the body through a small incision in the abdomen, as the doctor does when undergoing laparoscopy. The robot is controlled by joystick through a computer screen.

Dmitry Oleynikov and his colleagues used these robots to probe the live abdominal cavity as well as help cut their gallbladder. They are now improving so that robots can move more easily.

It is known that many robots can be inserted into the abdomen to clearly see a certain area at different angles.
