Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a bendable steering endoscope. Background technique [0002] The current endoscope generally controls its bending and steering through scissor handles and steering wires. The operation accuracy is not high, the control of the steering angle is not accurate enough, and the viewing angle is small. Due to the technical bottleneck caused by the size of the pipe and the blind angle, Bring hidden danger to the safety of operation. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned background technology, and provide a bendable steering endoscope, which has the characteristics of simple operation and convenient control of the steering angle. [0004] The invention provides a bendable steering endoscope, which includes a handle with a central through hole and a catheter, a steering channel and a working chann...
