An auxiliary extension device for stomatology

Abstract

The invention discloses an auxiliary extension device for stomatology, which comprises a tube body, one end of the tube body is fixedly connected with a drive box, and two extruding mechanisms are provided for sliding sealing in the drive box, and the tube body and the drive box are rotated through a same device. A rotating shaft, the upper end of the driving box is slidably inserted with an insertion rod that is clamped with the rotating shaft, and a liquid storage tube is fixedly installed in the tube body, and the liquid storage tube is connected to the driving box through the first air guide tube. There is a first piston plate, a plurality of elastic mechanisms are fixedly connected between the left side wall of the first piston plate and the inner wall of the liquid storage pipe, and a partition is fixedly installed in the liquid storage pipe on the right side of the first piston plate, and the upper end of the partition An air guide port is provided, and the rotating shaft rotates through the liquid storage tube, the first piston plate and the separator, and the liquid storage tube and the tube body on the right side of the separator are provided with connected medicine inlet holes. The invention is not only convenient for cleaning and administering medicine to the lesion in the oral cavity, but also does not stir and mix the medicine liquid.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary extension device for stomatology. Background technique [0002] The oral cavity is the initial part of the digestive tract. The front opening is connected with the outside world, and the back is continuous with the pharynx through the pharynx. There are teeth, tongue and other organs in the oral cavity. The front wall of the oral cavity is the lips, the side wall is the cheeks, the roof is the palate, and the floor of the mouth is the mucosa and muscles. The oral cavity is divided into the anterolateral oral vestibule and the posteromedial oral cavity by the upper and lower dental arches; when the upper and lower teeth occlude, the oral vestibule and the oral cavity proper can be communicated through the gap behind the third molars. Clinically, when the patient's teeth are tightly closed, the mouth gag or cannula can be placed through this channel to inject...
