Recent Advances in Surgical Instrumentation for Minimally Invasive Cardiac Surgery

低侵襲心臓手術（minimally invasive cardiac surgery：MICS）は，従来の開胸手術と比較して術後の回復が早く，患者の負担を軽減する新しい手術法として発展してきた．安全なMICS の普及には，継続的な手術機器の進歩が不可欠である．本稿では，MICS における最新の手術機器について解説する．

Minimally invasive cardiac surgery （MICS） has revolutionized the field of cardiac surgery by offering reduced surgical trauma, shorter hospital stays, and faster patient recovery compared to conventional median sternotomy. The success of MICS heavily depends on the continuous advancements in surgical instrumentation. This review discusses the recent innovations in surgical tools and technologies designed to enhance precision, safety, and efficiency in MICS. Key developments include robotic-assisted systems, endoscopic instruments, percutaneous devices, and novel visualization techniques. We further explore the clinical impact of these technologies and future prospects in the field.
