PURPOSE: To make tips mobile of forceps and a tube for injecting a contrast medium for an endoscope. CONSTITUTION: A coil spring (1) bent is mounted on forceps for an endoscope to bend the tip of the forceps beforehand. A rope (2) is fixed at a fixing part (3) on the hand side of a bent part and the rope (2) is inserted through the tip of a bent part of the coil spring (1) bent to be pulled to the way of the hand. Thus, the coil spring (1) bent shrinks linearly to extend the tip of the forceps. |
