Negative pressure device attached to dental tissues

Abstract

The invention provides a negative pressure device attached to hard dental tissues. The negative pressure device attached to the hard dental tissues is used for clinically treating odontogenic noninfectious diseases (such as adamantoblastoma and keratocyst) and odontogenic infectious diseases (such as pulpitis, periapical periodontitis, periapical abscess and periapical cyst) and comprises a closing component, a negative pressure machine, a negative pressure measurer, a liquid recoverer and a medicine holder. The negative pressure device, which is a dental negative pressure drainage device, is made of medical polymer materials and metal materials and is small in size and free from obvious foreign matter sense, the closing component can be fixed to the hard dental tissues, and a local negative pressure state is kept through the negative pressure machine, the negative pressure measurer and a negative pressure control valve, so that symptoms such as tissue absorption and tissue pain caused by positive pressure are decreased, and ossification generated by negative pressure is improved; exudation in the dental pulp cavity and the periapical part is drained to be sucked out, secondary pollution to oral microorganisms is avoided, infection risk is reduced, treatment period is shortened greatly and clinical efficacy of related odontogenic disease treatment is improved.

Description

technical field [0001] The present invention relates to the field of medical equipment, more specifically the present invention relates to a negative pressure device attached to dental tissue, which is used for clinical treatment of odontogenic non-infectious and infectious diseases, and can be used in ameloblastoma, Treatment of odontogenic jaw cyst, pulpitis, periapical periodontitis, periapical cyst, periapical abscess, periapical granuloma and other diseases. Background technique [0002] At present, decompression and drainage are mostly used in the clinical treatment of odontogenic diseases such as ameloblastoma and odontogenic jaw cyst. Open drainage is usually used for periapical granuloma. Clinical evidence-based medicine and scientific experiments have proved that these treatments have good curative effect. The purpose of decompression or open drainage is to make a channel for local inflammation, release pressure and relieve pain. And local damage, reduce the press...

Problems solved by technology

However, this will lead to many follow-up problems, such as the long treatment period of decompression and drainage currently used clinically, which increases the chance of postoperative cyst infection, and the gums are easy to grow into the drainage port, requiring a second fenestration operation; while open drainage will Bring such as oral saliva, food debris, various oral microorganisms and infected tissues into the open pulp cavity and even periapical, which may lead to more serious inflammation and infection
