Laryngeal lesions can cause great inconvenience to patients. Early diagnosis and corresponding treatments are critical to the survival of patients. However, the diagnosis and precise removal of tumors remain a challenge under the use of a white light laryngoscope. In this work, an integrated, multifunctional laryngoscope was designed and tested for the imaging evaluation and precision laser surgery for laryngeal tissue. This integrated diagnostic and therapeutic endoscopic system included two imaging modes (i.e., optical coherence tomography and white light endoscopy) and a laser ablation treatment mode. The endoscope had a common-path design to ensure that the same position could be imaged and treated simultaneously. The ex vivo porcine larynx experimental results showed that the system imaging modes could simultaneously acquire both superficial and cross-sectional images of the sample tissue, and the ablation treatment could be performed under imaging guidance. This multifunctional laryngoscope has great potential for the early diagnosis of and accurate laser ablation surgery for laryngeal tumors.

集成式多功能喉镜用于医疗诊断和治疗

喉部病变会给患者带来极大的不便。早期诊断和相应的治疗对患者的生存至关重要。然而，在使用白光喉镜的情况下，诊断和精确去除肿瘤仍然是一个挑战。在这项工作中，设计并测试了集成的多功能喉镜，以对喉组织进行成像评估和精密激光手术。这种集成的诊断和治疗性内窥镜系统包括两种成像模式（即，光学相干断层扫描和白光内窥镜检查）和激光消融治疗模式。内窥镜具有共通路径设计，以确保可以同时对相同位置进行成像和处理。猪喉的离体实验结果表明，系统成像模式可以同时获取样本组织的表面和横截面图像，并且可以在成像指导下进行消融治疗。这种多功能喉镜在早期诊断和精确的激光消融手术中具有巨大的潜力。
