zouzui@smmu.edu.cnOpen Accesszouzui@smmu.edu.cnWith the evolution of traditional direct laryngoscopes into video-assisted laryngoscopes, the viewing angle provided by video laryngoscopes has been substantially enlarged, enabling more intuitive and clearer visualization of pharyngeal structures and the glottis. However, the design of video laryngoscopes generally retains the relatively bulky blade carrier of traditional direct laryngoscopes. During routine use, this design may still limit the field of view, necessitating significant jaw elevation to obtain a clear view [1, 2]. To address this limitation, our team developed a slim exquisite easy-exposing video laryngoscope (SEE-VL), a slender and refined device designed to facilitate easier glottic visualization (Registration Certificate No.: Su Xie Zhun 20252082044).
The most significant difference between SEE-VL and traditional video laryngoscopes (e.g., UESCOPE® video laryngoscope) lies in the optimized cross-sectional design of blade carrier. While ensuring adequate exposure of the laryngeal structures, SEE-VL minimizes additional trauma to the oral cavity and larynx, providing more intraoral space for establishing an artificial airway. Additionally, SEE-VL is equipped with a high-resolution display, enabling clearer visualization of the laryngeal structures and glottis (Figure 1).
