Description

Injectable medicine-carrying gel device for periodontitis treatment Technical Field The invention relates to the technical field of medical equipment, in particular to an injectable medicine-carrying gel device for treating periodontitis. Background Periodontitis, also known as destructive periodontal disease, is a chronic inflammatory disease that is mainly caused by the destruction of periodontal tissue by bacteria in dental plaque, which affects periodontal support tissues (including gums, periodontal membranes, alveolar bone, and cementum). The treatment of periodontitis often needs to directly send medicine into periodontal pocket depths, traditional method mainly uses ordinary syringe or gingival sulcus flusher, but traditional medicine device is when using, and ordinary sharp needle is liable to stab the bag bottom, causes pain or hemorrhage, and the syringe needle is difficult to adapt to the crooked route of periodontal pocket, leads to the medicine to only stay at the sack, can't evenly distributed in whole bag inner wall, and needs artifical manual push medicine, can't accurate accuse volume, so proposes an injectable medicine carrying gel device that periodontitis treatment was used and solves above-mentioned problem.
