Abstract

The invention discloses a dental pulp cavity paste filling apparatus which comprises an injection syringe and a filling needle. The filling needle comprises a positioning trocar and an injection needle, a positioning trocar bed and an injection needle bed are mounted at the bottom of the positioning trocar and the bottom of the injection needle, the positioning trocar is communicated with the inside of the positioning trocar bed, the injection needle is communicated with the inside of the injection needle bed, and a three-edged needle head is arranged at the head end of the positioning trocar; paste outlets are formed in the outer wall of the head end of the positioning trocar, the injection needle is movably inserted into the positioning trocar, and a sealing plug is mounted at the head end of the injection needle bed. The dental pulp cavity paste filling apparatus has the advantages that the dental pulp cavity paste filling apparatus is reasonable in structure and convenient to use; connection gaps between the positioning trocar bed and the injection needle bed can be plugged by the sealing plug, and accordingly paste can be prevented from flowing out; a limit sleeve can rotate and can linearly move on a threaded tube, accordingly, limit effects of the limit sleeve can be adjusted, and the insertion depths can be accurately controlled.

Description

technical field [0001] The invention relates to a medical device, in particular to a pulp chamber paste filler. Background technique [0002] Dental pulp tissue mainly includes nerves, blood vessels, lymph and connective tissue, as well as odontoblasts arranged around the pulp, whose role is to build dentin. When there is caries or other lesions in a certain part of the crown, a layer of dentin, called restorative dentin, can be formed on the inner wall of the corresponding pulp cavity to compensate for the thickness of the crown, which is the protection of the dental pulp. reaction. [0003] The function of pulp tissue is to form dentin, which has the ability of nutrition, feeling and defense. The pulp nerve is particularly sensitive to external stimuli, which can produce unbearable severe pain. [0004] Dental pulp is loose connective tissue that contains cells, fibers, nerves, blood vessels, lymphatic vessels and other extracellular matrix. [0005] The pulp tissue is...
