Detailed Description
In order to explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following embodiments are described in detail with reference to the accompanying drawings.
As shown in fig. 1, a dental treatment instrument comprises a handle 10 and two holding arms 20, wherein the front ends of the holding arms 20 are respectively provided with a working tip 30, the outer sides of the two holding arms 20 are respectively provided with a finger pressing plate 21, the inner side of one holding arm 20 is provided with a positioning bolt 23, and the inner side of the other holding arm 20 is provided with a positioning hole 22 matched with the positioning bolt 23;
as shown in connection with fig. 2, the tip includes a gripping portion at the front end and a shearing portion at the rear end; grooves 31 are formed in the clamping portion, and a cutting edge 32 is arranged in at least one groove 31; the inner side surface of the head of the clamping part 30 is provided with anti-skid grains 33.
The utility model discloses an apparatus for paediatrics dental treatment, the main part is the tweezers of dentistry, and the finger pressure dish is for fixing the ellipse or the circular slab in the outside, can cover and have rubber membrane, antiskid, waterproof. The anti-skid grooves can be cross grains, also can be cross grains or elastic rubber particles. The rubber film and the elastic rubber particles can resist the high temperature and high pressure of moist heat sterilization.
