Description

Technical Field

[0001] The utility model relates to the technical field of dental forceps for stomatology, in particular to a pair of dental forceps for stomatology. Background Art

[0002] In oral medicine, tooth extraction is very common, and tooth extraction forceps are essential medical instruments for tooth extraction surgery. Tooth extraction forceps are instruments used to clamp the crown or root of the tooth and loosen and dislocate the tooth through wedging, shaking, twisting and pulling.

[0003] The utility model with the existing authorization application number CN211381865U discloses a dental extraction forceps for oral use, comprising a dental extraction forceps body, an elastic device for keeping the dental extraction forceps body in a normally open state is provided between the two clamp handles of the dental extraction forceps body, a accommodating cavity for containing a micro dental extraction tool is provided inside the two clamp handles, the accommodating cavity is provided with a detachable plug, the elastic device comprises an installation cavity, and a torsion spring passing through the installation cavity through a pin shaft, and limiting grooves provided at both ends of the inner side of the installation cavity, and movable pressure blocks provided at both ends of the installation cavity, the limiting groove is provided with a vertical notch on one side away from the inner wall of the installation cavity, the two ends of the torsion spring are respectively passed through the notch and arranged inside the limiting groove, and matched with the movable pressure block, and the two clamp handles are pressed on the movable pressure block.

[0004] With the above technical solution, the setting of the elastic device avoids manual stretching of the tooth extractor during the expansion process, avoids soreness of the doctor's fingers, and helps to improve the efficiency of the operator. However, with the above technical solution, when the doctor fixes and extracts the patient's teeth, the doctor cannot limit the handle after fixing the patient's teeth, so the doctor needs to continue to hold the handle. Holding it for a long time can easily cause soreness in the doctor's hands, and the angle of the pliers mouth cannot be adjusted, which makes it inconvenient to extract teeth in different positions of the patient, making it less practical.
