Modular design—— The end of the laser guide wire and the suction port of the device are configured through modules to meet the different needs of surgical, respiratory, and urological procedures. This lowers material consumption in compliance with the design principle of sustainability.Intuitive GUI——The handle of the device has a high degree of fit with the palm, ensuring flexible and efficient operation while effectively reducing the fatigue caused by long-time holding.Wide application——Conventional electronic endoscopes are limited to use within hospitals and fail to meet the needs of out-of-hospital surgeries in case of disasters and accidents. The device comes with two types of clients, and the mobile pad client can meet the needs of out-of-hospital surgeries.
