<p>A soft tube for use in a medical endoscope. The soft tube is provided with a channel running along the axial direction. The channel is divided into a steering control channel (1), an imaging and lighting sensor channel (2), and a working channel (3). The cross-sectional area of the working channel (3) is greater than the cross-sectional area of the steering control channel (1) or that of the imaging and lighting sensor channel (2). The present invention merges the working channel and a flushing channel into one channel, providing an enlarged cross-sectional area, an expanded range available for movement during operation, improved convenience in equipment operation, and increased flow, while the three cavity-channel design allows for further simplified manufacturing, low manufacturing costs, conserved costs, and facilitated promotion.</p> |
