Olympus Endoscopy Technology Innovation: Leading the New Trend of Gastrointestinal Diagnosis and Treatment

1. Olympus' new technology

1.1 Innovation of EDOF Technology

On May 27, 2025, Olympus announced its EZ1500 series endoscope. This endoscope adopts a revolutionary Extended Depth of Field (EDOF) technology ™ The technology has successfully obtained FDA 510 (k) approval. This important milestone means that this endoscope will bring unprecedented changes to the examination, diagnosis, and treatment of gastrointestinal diseases.

EDOF technology divides light into two beams by using two prisms, providing clearer fully focused images and significantly improving the accuracy of gastrointestinal examinations. Compared with the previous generation of products, it has higher visibility and lower blurriness. EDOF technology, as the core concept of this endoscope, cleverly uses two prisms to accurately split the light entering the lens into two beams, capturing near focus and far focus images respectively, and ultimately fusing them into a fully focused image. In clinical applications, this technology provides doctors with a clearer field of view, allowing them to focus on the lesion throughout the entire process, significantly improving the accuracy of gastrointestinal mucosal lining examination.

Compared to the previous generation Olympus scope, EDOF technology has demonstrated significant advantages, including higher visibility and lower ambiguity. Taking CF-EZ1500DL/I colonoscope as an example, in conventional mode, its focusing distance is closer (3mm compared to -5mm) and there is no blurring phenomenon, thereby reducing the need for mode switching and improving examination efficiency.

1.2 Improvement of Operation Design

In addition, the GIF-EZ1500 gastroscope and CF-EZ1500DL/I colonoscope are also ingeniously designed in terms of operation. They are equipped with lightweight ErgoGrip ™ The control part, when connected to the EVIS X1 CV-1500 video system center, is compatible with texture and color enhanced imaging (TXI) ™）、 Red Bicolor Imaging (RDI) ™） And narrowband imaging ™ （NBI ™） Waiting for various advanced technologies. The new device features a lightweight ErgoGrip ™ The control part makes the operation more ergonomic, compatible with various advanced technologies, and enhances the user experience.

It is worth mentioning that the ErgoGrip of EVIS X1 endoscope ™ The control part is 10% lighter than the 190 series, and its circular handle and easy-to-use angle control knob and switch design fully consider the needs of small hand users, effectively improving the operability of the endoscope.

2. The significant importance of the product

EVIS X1 ™ The endoscopic system has brought revolutionary changes to the detection, characterization, and treatment of gastrointestinal diseases through its innovative and user-friendly diagnostic and treatment technology, as well as improved endoscopic operating performance. This system provides excellent patient care to countless endoscopists and surgeons on a daily basis.

Olympus' EZ1500 series endoscope introduces revolutionary EDOF technology, which improves diagnosis and treatment effectiveness through various auxiliary functions, marking technological progress in the diagnosis and treatment of gastrointestinal diseases and bringing hope for precise and efficient services. In addition to revolutionary EDOF technology, the system is also equipped with a series of powerful auxiliary functions, such as TXI ™ Technology enhances the visibility of lesions and polyps by enhancing the color and texture of images; RDI ™ Technology focused on enhancing the visibility of deep blood vessels and bleeding points; NBI ™ Technology that utilizes specific wavelengths absorbed by hemoglobin to enhance visual observation of mucosal and vascular patterns; And BAI-MAC ™ Technology corrects the brightness level of endoscopic images through contrast maintenance function. However, it is worth noting that these auxiliary technologies such as TXI, RDI, BAI-MAC, and NBI cannot replace histopathological sampling as a diagnostic tool. They are designed to be compatible with Olympus ® White light imaging complements each other and jointly improves the diagnosis and treatment level of gastrointestinal diseases.

The approval of the Olympus EZ1500 series endoscope will undoubtedly bring new hope to the diagnosis and treatment of gastrointestinal diseases, promote technological progress in this field, and provide patients with more accurate and efficient medical services.
