An assisted clearing device for salivary gland ducts
The application relates to the field of auxiliary unblocking technology of salivary gland ducts, and discloses an auxiliary unblocking device for salivary gland ducts, which comprises a conveying mechanism fixedly connected to the outer wall of a main body and used for conveying or extracting physiological saline, a pushing mechanism slidingly connected to the inner wall of the main body and used for plugging the salivary gland duct, and a drainage mechanism fixedly connected to the inner wall of the conveying mechanism and used for controlling the flow direction of the physiological saline. When the taper pipe passes through impurities, the impurities are arranged between the taper pipe and the main body, the operator pushes the push rod, the sponge ball reaches the inside of the salivary gland duct, the sponge ball is blocked by the elasticity of the sponge ball and the spring sheet, the physiological saline is arranged between the sponge ball and the end of the main body, the inside of the duct is rapidly accumulated with enough pressure, effective turbulent flow is formed, the impurity dispersion efficiency is improved, and the cleaning speed is accelerated.
