AI Technical Summary

Technical Problem

The rigid design of the guide scraper in existing gastroscopy catheter insertion aids leads to lubrication control failure, which cannot dynamically adapt to changes in the outer diameter of the catheter. This results in uneven lubricant distribution and increased friction, affecting examination efficiency and safety.

Method used

Multiple guide scrapers are used to form a conduit channel with elastic or movable connectors and support components. Adjustment components control the scraper spacing to achieve dynamic inner diameter matching and segmented scraping, reducing lubricant stripping and friction.

Benefits of technology

It achieves dynamic matching between the inner diameter of the catheter channel and the outer diameter of the catheter, ensuring uniform distribution of lubricant, reducing friction and viscous resistance, improving inspection efficiency and safety, and adapting to different catheter models without the need to replace the auxiliary device.

Abstract

This application relates to the field of medical auxiliary device technology, and more particularly to a gastroscopy catheter insertion assistance device, comprising N guide scrapers, N connectors, N adjusting components, and a support component, where N is an integer greater than or equal to 2. The N guide scrapers are elastically or movably connected to the support component via the N connectors, forming a catheter channel. The N adjusting components are connected to each other to adjust the distance between the guide scrapers and the support component. The catheter channel is formed by the discontinuous enclosure of multiple independent guide scrapers, and the elastic or movable connection between the connectors and the support component allows each guide scraper to have independent displacement capability. The movement of the guide scrapers is controlled by the adjusting components, thereby achieving dynamic adjustment of the effective inner diameter of the catheter channel. By adjusting the distance between the guide scrapers and the support component, the distance between the N guide scrapers can be adjusted, matching the inner diameter of the channel with the outer diameter of the catheter, thus improving the uniformity of the lubrication layer distribution.
