Embodiment Construction

[0015] The above and other embodiments and advantages of the present invention are clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are only some, not all, embodiments of the present invention.

[0016] In one embodiment, as Figure 2-4 shown. The spoon-shaped tool for subgingival scaling provided in this embodiment includes a handle 1 and a working end 2 . The working end 2 includes a neck 21, which is very thin for inserting between the teeth. A spoon-shaped fixing block 22 is provided at the end of the neck 21 , and the spoon-shaped fixing block 22 is larger than the neck 21 , and the spoon-shaped fixing block 22 is integrally arranged at the end of the neck 21 . The opening direction of the spoon-shaped fixed block 22 is perpendicular to the direction of the neck 21 and the one-way tooth groove 23 along the circumferential direction. The one-way tooth groove 23 includes an inner groove area 231 and...

Abstract

The invention provides a spoon-shaped device for subgingival curettage in the department of stomatology, which includes a handle and a working end. The working end includes a neck, and a spoon-shaped fixing block is provided at the end of the neck. The direction of the unidirectional alveolar is vertical and along the circumferential direction. The unidirectional alveolar includes an inner groove area and an outer groove area from the inside to the outside. The side wall of the inner groove area is set to be rigid, and the side wall of the outer groove area is set to be flexible. The one-way tooth groove is provided with a tension spring along the slotting direction, and the tension spring is connected to the spoon-shaped movable block opposite to the spoon-shaped fixed block. block, and the one-way tooth block is set as rigid; under the tension of the tension spring, the one-way tooth block is inserted into the one-way tooth groove and its movement is limited by the inner groove area. When the spoon-shaped movable block is pulled outward so that the one-way tooth block is located In the outer groove area, the spoon-shaped movable block can be unidirectionally rotated along the circumferential direction to adjust the angle of the blade surface and the neck end surface.

Description

technical field [0001] The invention relates to the technical field of precision instruments for stomatology treatment, in particular to a spoon-shaped device for subgingival curettage in the stomatology department. Background technique [0002] Subgingival curettage is the use of fine instruments to scrape subgingival plaque, subgingival calculus and diseased cementum, etc., so as to form a smooth and smooth root surface with good histocompatibility, which is conducive to the formation of new periodontal attachments. [0003] The current commonly used instruments are spoon-shaped devices. Because they need to fit the tooth surfaces of different teeth, there are two specifications for the working end of the spoon-shaped device, such as figure 1 shown. On the left working end, the blade surface 01 and the neck end surface 02 form an angle of 90 degrees, which is used for ordinary tooth surfaces. The working end on the right has a 70-degree angle between the blade face 01 an...
