The Enduring Legacy of Nāḍī Yantra: From Sushruta's Wisdom to Modern Surgical Innovation

Surgery has long stood at the forefront of medical science, and among the earliest contributors was Ayurveda—the ancient Indian medical system. Acharya Sushruta, a pioneering figure in surgery, not only documented operative techniques but also introduced specialized instruments, including Nāḍī Yantras, whose design and utility strikingly resemble modern endoscopic devices. This paper critically explores these historical instruments, evaluates their structural and clinical integrity, and compares them to contemporary surgical tools. The study highlights the relevance of Sushruta’s contributions in today's minimally invasive procedures and underscores the scientific foresight embodied in ancient Ayurvedic literature.
