Description

A car needle, dentistry low-speed cell-phone and dentistry high-speed cell-phone for periodontal operation

Technical Field

The application relates to the technical field of medical instruments, in particular to a machine needle, a dental low-speed handpiece and a dental high-speed handpiece for periodontal surgery.

Background

Periodontitis has become the sixth most chronic disease in humans. The most important pathological change of periodontitis is that the combined epithelium of the gum moves towards the root of the tooth to form periodontal pockets, which further cause the absorption of alveolar bone below the gum, and gradually lead to tooth loosening, displacement and falling off. The bone defects caused by the deepened periodontal pocket and alveolar bone resorption in turn become factors that promote the accumulation of plaque, thus aggravating the condition and treatment difficulty of the patient. For the deep periodontal pocket or the periodontal pocket with the bifurcation lesion, the periodontal basic treatment such as scaling, curettage and the like is difficult to completely eliminate, and the condition is that the deep periodontal pocket and the exposed periodontal pocket area are cleaned of plaque, tartar and a large amount of inflammatory granulation tissue under direct vision by adopting the periodontal operation, namely flap surgery.

In periodontal surgery, the instruments currently used to clean the area of the root bifurcation are primarily curettes. The application method of the curette comprises the following steps: the instrument is inserted into the bifurcation area and then the dental calculus and inflammatory granulation tissue are manually scraped. The method is time-consuming and labor-consuming, and the granulation tissue is tightly adhered to the tooth root surface and the alveolar bone; if two (or three) posterior teeth are too close to each other, the entry of the scaling device is obstructed; and complex factors such as root surface concave ditches, bone morphological damage and the like greatly increase the difficulty of manually scraping granulation tissues in the root bifurcation area.

An ultrasonic scaler equipped with an ultrasonic head for a bifurcation is currently commercially available, fig. 1 shows a schematic structural view of a conventional ultrasonic scaler, fig. 2 is an enlarged view of a circled portion in the ultrasonic scaler of fig. 1, fig. 3 is a view illustrating one use state of the ultrasonic scaler of fig. 1, and fig. 4 is a view illustrating another use state of the ultrasonic scaler of fig. 1. The ultrasonic working head of the ultrasonic scaling instrument has a good effect on hard root surface sediments such as tartar and the like, but has a poor effect on cleaning soft tissues such as granulation and the like. Therefore, how to develop a surgical tool capable of scraping all granulation tissues as quickly as possible to prevent the progression of the disease or recurrence and striving for a certain degree of new attachment base of periodontal tissues has become a problem to be solved in the field of periodontal surgery.
