Technical Field

[0001] The utility model relates to the field of endoscopes, in particular to a double-channel endoscope. Background Art

[0002] With the development of technology, endoscopes have better served as the hands and eyes of doctors, playing an irreplaceable role in places that doctors cannot see or are difficult to handle. The double-channel endoscope used in the digestive tract can more delicately handle difficult and complicated diseases inside the digestive tract and minimize damage and pain to patients.

[0003] At present, endoscopic technology is relatively mature, but it still needs to be optimized in practical application. According to feedback from many doctors, some large endoscope controllers will cause soreness in the hands when used continuously, which will affect the accuracy of subsequent work. In addition, doctors often need to control the controller with one hand when performing endoscopic operations. Existing one-handed operation controllers usually only support one hand operation, which means that when changing hands, doctors may not be able to complete the operation smoothly due to differences in hand holding methods.
