Novel dental forceps for department of stomatology

Abstract

The invention relates to the technical field of dental forceps, in particular to novel dental forceps for the department of stomatology. The novel dental forceps comprise two clamps and two clamp arms, wherein a connecting piece is arranged between the two clamp arms; a first mounting groove is formed in one end of each clamp arm; a driven shaft is rotationally connected to one end of each first mounting groove; the peripheral side face of each driven shaft is fixedly connected with one end of the corresponding clamp; a plurality of meshing teeth are arranged on the peripheral side face of each driven shaft, and a worm is further arranged on one side of each driven shaft; the worm is meshed with the corresponding driven shaft; the end, away from the driven shaft, of the worm is engaged with a driving gear. By using an adjusting knob, the driving gears, the worms, the driven shafts and the clamps, a doctor can rotate the adjusting knob, then force is transmitted step by step through thedriving gears, the worms and the driven shafts, the angle of the clamps can be changed, flexibility is improved, force exertion is convenient, and convenience is brought to the doctor; and by using telescopic arms, the doctor can extend the telescopic arms in the original length of the clamp arm, so that the practicability is improved.

Description

technical field [0001] The invention belongs to the technical field of tooth extraction forceps, in particular to a novel dental tooth extraction forceps. Background technique [0002] Dental extraction forceps are instruments used to hold the crown or root of a tooth and loosen and dislocate the tooth through wedging, shaking, twisting, and traction. Tooth extraction forceps are divided into adult tooth extraction forceps and children tooth extraction forceps, and the gill structure of the tooth extraction forceps has a penetrating gill structure and a stacked gill structure. [0003] For example, Chinese Patent No. CN201617964U, whose application date is March 2, 2010, discloses a new type of tooth extraction forceps, although it provides a new type of tooth extraction forceps with small jaws and a clamping direction perpendicular to the direction of the handle. However, it does not solve the problem that the existing tooth extraction forceps often need to change the angl...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings in the prior art, the present invention provides a new type of dental extraction forceps, which can effectively solve the problem that doctors in the prior art often need to change the angle or use other devices to extend Forceps arms, however, these have brought inconvenience to the doctor and reduced the efficiency of tooth extraction
