Background
At present, most of clinical treatment of odontogenic diseases such as ameloblastoma and odontogenic jaw cyst adopt decompression drainage, open drainage is generally adopted in treatment of pulpitis, periapical periodontitis, periapical cyst, periapical abscess, periapical granuloma and the like, clinical evidence-based medicine and scientific experiments prove that the therapies have good curative effect, and decompression or open drainage aims to ensure that local inflammation has a channel, so that pressure is released, pain and local injury are relieved, pressure in a sac cavity is reduced, new bones around a pathological change area are formed after pressure is eliminated, the sac cavity is reduced, and accordingly jaw and tooth anatomical structures can be preserved, surgical wounds are reduced, and recurrence rate is reduced. However, such a method causes many subsequent problems, for example, the treatment period of the currently clinically adopted reduced pressure drainage is long, the chance of postoperative infection of the capsular cavity is increased, the gingiva is easy to grow into the drainage opening, and a secondary windowing operation is needed, and the open drainage can cause saliva, food debris, various microorganisms and infected tissues in the oral cavity to enter the open dental pulp cavity or even around the root tip, and more serious inflammation and infection may possibly occur. Therefore, how to shorten the treatment period, reduce the infection chance and reduce the traumatic treatment becomes a research hotspot. The jaw is the most active part in human tissue, and the osteoclast can be activated when meeting pressure, so that bone absorption is caused, the osteoblast can be activated when meeting tension, so that the bone formation process is caused, the principle of negative pressure is similar to that of the negative pressure, so that the apical inflammation or jaw cyst sac cavity hydrostatic pressure can be changed into negative pressure stress, lesion expansion growth factors caused by the hydrostatic pressure in the sac cavity are eliminated, and the bone tissue grows towards the sac cavity, so that the disease course is shortened, and the infection is reduced.
The inconvenient regulation of current department of stomatology negative pressure device can't come height-adjusting according to medical personnel's demand, and when carrying out the negative pressure suction treatment, is inconvenient to be collected.
