AI Technical Summary

Technical Problem

In existing technologies, the sponge table is a single piece, which makes it difficult to clean root canal preparation instruments during use, resulting in low cleaning efficiency and difficulty in effectively removing residual tissue and debris.

Method used

An immediate cleaning device for root canal preparation instruments in endodontics has been designed, comprising a detachable sponge block and an elastic element mounting clip. The elastic element keeps the sponge block in close contact with the instrument. Combined with a liquid pump and a liquid reservoir, the device enables automatic wetting of the sponge block and cleaning of the instrument.

Benefits of technology

It improves instrument cleaning efficiency, effectively removes residual tissue and debris, and integrates a collection tank to collect cleaning materials, simplifying the cleaning process.

Abstract

The purpose of this invention is to provide an immediate cleaning device for root canal preparation instruments in endodontics, relating to the field of medical device technology. Two mounting clips are rotatably mounted on the housing, and sponge blocks are detachably mounted on the clips. Under the action of two elastic elements, the upper ends of the two mounting clips rotate towards each other, causing the sponge blocks on the clips to adhere tightly together. In use, pressing the pressure plate causes the two mounting clips to rotate in opposite directions, the instrument is placed between the two sponge blocks, and releasing the pressure plate allows the two sponge blocks to hold the instrument. Pulling the instrument allows for wiping and cleaning. A collection frame is provided on the housing to collect tissue debris that falls off during wiping. A liquid reservoir is also provided inside the housing to store alcohol, which is connected to the mounting clips via a conduit. A pump draws alcohol into the mounting clips to wet the sponge blocks.
