Japanese researchers said Tuesday they had developed a self-propelled remote controlled capsule endoscope that can “swim” through the digestive tract. pills that survey the wild and nauseating gastric landscape have been done before but how about one that can “swim” to input from a doctor controlled joystick!
They have succeeded in capturing images inside a person’s stomach and colon using the tadpole-shaped capsule as a first step toward its clinical application, the scientists said.
The device, nicknamed the “Mermaid”, is about one centimetre (0.4 inches) in diameter and 4.5 (1.8 inches) long and has magnetic driving gear that allows for precise control of its direction and location.
Doctors control the capsule’s by useing a joystick to movements, watching them on a monitor screen. It can be swallowed for examination of the stomach or inserted rectally for the colon.
The research was announced at an international conference on digestive diseases in Chicago, Illinois, in May, according to the team, which included scientists from Ryukoku University and Osaka Medical College.
The Mermaid was demonstrated before Japanese media at Osaka Medical College in Osaka’s suburbs on Tuesday.
“By remotely controlling the capsule, we can precisely photograph the area which needs to be tested,” Osaka Medical College professor Kazuhide Higuchi said.
“It can examine the digestive canal from the oesophagus to the colon in a few hours. It reduces burdens on patients and can led to the discovery of cancer,” he said.
