AI Technical Summary
Existing flexible sinus endoscopes lack sufficient rigidity when pushing tissues within the nasal cavity, making it difficult to effectively reach the delivery site and limiting their use in complex nasal environments.
Design a rigid bending electronic sinus endoscope, including a rigid tube and an operating handle. The rigid tube is divided into a rigid bending section and a rigid straight section. A light source and a camera element are set at the distal end. The rigidity provides stable support and is used in conjunction with the operating port and channel for inspection and operation.
It ensures that the rigid curved part can be smoothly advanced into the nasal cavity, providing stable support, enabling effective examination and manipulation of the internal structures of the nasal cavity, adapting to different anatomical structures, and improving the accuracy and efficiency of examination and treatment.
