The traditional endoscope has its limitations: 1. The observed picture always has the same angle, meaning there is a blind spot during examinations; 2. Only a partial picture can be transmitted; 3. It is not convenient to adjust lens direction when space is limited. The panoramic endoscope was conceived to solve these problems. The lens angle can be adjusted by turning the dial on the handle, providing the doctor a comfortable experience. The device provides 360 degrees of observation with no blind spots, and transmits full 360° panoramic images.
