Innovative Channel-Less High-Resolution Dacryoendoscope

Akemi Iwasaki


Purpose

Conventional Ruido dacryoendoscopes® (Fibertech Co., Japan) incorporate a 0.3 mm irrigation channel, necessitating gas sterilization and prone to clogging. We report a novel dacryoendoscope design that removes the irrigation channel from the lacrimal duct insertion part, thereby enhancing usability and cleanliness.


Methods

The dacryoendoscope comprises two main components: the insertion segment and the grip. The insertion segment contains the lens, image guide fiber, and light guide fiber, excluding the irrigation channel. In contrast, the grip includes a 1.1mm diameter irrigation channel. A specialized adapter links the grip to the insertion segment, enabling attachment of an 18-gauge, 51-mm catheter, allowing saline to flow from the grip’s irrigation channel, through the adapter, and along the gap between the catheter and the dacryoendoscope’s insertion segment. The adapter can be easily slid back and forth with the fingers. By moving the adapter, it is possible to extend or retract the catheter from the tip of the dacryoendoscope.


Results

The minimum diameter of the grip’s irrigation channel is 1.1mm, making it suitable for low-temperature hydrogen peroxide plasma sterilization and brush cleaning. Furthermore, the imaging resolution has been enhanced from 10,000 to 15,000 pixels, significantly improving the visual detail obtainable within the lacrimal duct.


Conclusion

The innovative channel-less dacryoendoscope design significantly improves cleanliness and provides detailed visualization of the lacrimal duct, marking a substantial advancement in dacryoendoscopy technology.
