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.
