This is a wire that responds to the need to give robots and medical devices/equipment a sense of touch. It is a product that integrates the functions of a wire cable that operates the tip and a wire harness that transmits electrical signals. It is very useful in situations where it is difficult to wire in narrow spaces. By attaching pressure, temperature, and various other sensors to the tip, it becomes possible to operate while obtaining various data in real-time from remote locations that are out of reach of human hands.

The torque loop is used for the operation of instruments in endoscopic surgery. Toxen can provide torque loops with various configurations. Toxen's products excel in torque transmission, with a very small difference between the rotation angle at the hand and the rotation angle at the tip. As a result, doctors can operate the instruments as intended.
