Latest Innovations in Illumination and Engineering Equipment for Thoracic Surgery

胸部外科領域の手術では，きわめて高い精密性と安全性が要求される．術野を明瞭かつ均一に照らす照明器具や，高度な光学技術による視野確保は，術後成績の向上や患者負担の軽減に直結する重要な要素である．近年，胸腔鏡下手術やロボット支援下手術などの低侵襲手術が普及し，それに対応した照明技術および光学デバイスが著しく進歩してきた．本稿では，胸部外科領域における照明器具・光学機器の種類や最新動向を概説するとともに，今後の展望について述べる．

In thoracic surgery, where precision and safety are paramount, advanced lighting and optical technologies play a critical role in enhancing surgical outcomes. Recent developments in lighting systems have improved brightness, reduced heat generation, and enabled more accurate color rendering, supporting safer and more efficient procedures. The shift toward minimally invasive techniques, such as thoracoscopic and robot-assisted surgeries, has further accelerated the need for high-quality visualization tools. Three-dimensional （3D） imaging, high-resolution displays, and fluorescence-guided visualization now allow for better identification of anatomical structures. Furthermore, augmented reality （AR） and artificial intelligence （AI） are being integrated into surgical practice. Preoperative imaging data can be reconstructed in 3D and overlaid during surgery to enhance accuracy in tumor localization and vascular mapping. Wearable optical devices and digital operating room systems are also improving communication and collaboration among surgical teams, allowing for real-time sharing of visual information and remote guidance. These technologies are increasingly contributing not only to surgical precision but also to team-based workflows, education, and training. Looking ahead, real-time AI-AR fusion systems and remote navigation support may further transform thoracic surgery by enabling safer, more informed decision-making in complex procedures.
