Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a quick-change dental cleaning device working tip. Background Technology

[0002] During dental treatment, working tips are connected to various devices to clean teeth. Currently, cleaning the front, left, and right sides of the mouth is done using straight working tips connected to a connecting handle. A straight working tip consists of a vertically extending connecting section connected to the connecting handle at one end and a cleaning section connected to the upper end of the connecting section at the other end. A drive mechanism connected to the other end of the working handle drives the working tip to move to the left to achieve cleaning. This type of working tip is uncomfortable when cleaning the left and right sides of the teeth. Utility Model Content
