Clamp channel pipe for endoscope

The utility model discloses a forceps channel pipe for endoscope, which comprises a polytetrafluoroethylene hose, two annular clamping components and a spring, the right end of the polytetrafluoroethylene hose is provided with a bending part which is integrated with the polytetrafluoroethylene hose, the spring is sleeved on the bending part, and the two annular clamping components are connected with the spring. One end of the spring is fixedly connected with one end of the bending part through one annular clamping assembly, and the other end of the spring is fixedly connected with the other end of the bending part through the other annular clamping assembly. According to the forceps channel pipe for the endoscope, the spring is clamped and fixed to the bent part through the annular clamping assembly, so that the wall thickness of the polytetrafluoroethylene hose and the wall thickness of the bent part can be properly reduced, the inner diameter of the forceps channel pipe is increased as much as possible on t
