The Sleeve-Type Endotracheal Tube (STET) is an innovative airway management device designed to address the limitations associated with traditional double-lumen tubes (DLTs) and bronchial blockers (BBs). Utilizing a modular structure comprising an outer sheath tube, inner sheath tube, and blocking tube, the STET offers increased flexibility in one-lung ventilation (OLV) and airway clearance, thereby reducing airway trauma and improving ventilation efficiency. Its dual-cuff system ensures stable positioning, while its versatile design accommodates diverse patient populations, including pediatric patients and those with difficult airway anatomy. This review explores the structural characteristics, manufacturing processes, clinical advantages, potential limitations, and practical applications of the STET. After multiple rounds of structural optimization, the STET design has successfully advanced into pilot production. Preliminary validation results from small-scale manufacturing and functional testing demonstrate promising structural stability, operational flexibility, and safety performance. The STET represents a significant advancement in airway management, holding substantial potential to improve patient outcomes and transform clinical practice in thoracic surgery and critical care anesthesiology.
袖式气管内导管（STET）是一种创新的气道管理设备，旨在解决与传统双腔导管（DLT）和支气管阻塞器（BB）相关的局限性。STET采用模块化结构，包括外鞘管、内鞘管和阻塞管，在单肺通气（OLV）和气道清理方面具有更高的灵活性，从而减少气道创伤并提高通气效率。其双套囊系统确保定位稳定，而其通用设计适用于不同的患者群体，包括儿科患者和气道解剖结构复杂的患者。本综述探讨了STET的结构特点、制造工艺、临床优势、潜在局限性和实际应用。经过多轮结构优化，STET设计已成功进入试生产阶段。小规模制造和功能测试的初步验证结果表明，其结构稳定性、操作灵活性和安全性能前景良好。STET代表了气道管理方面的重大进步，在改善患者预后以及改变胸外科和重症监护麻醉学的临床实践方面具有巨大潜力。
