Specific implementation mode
The embodiment of the utility model is described in further detail with reference to the accompanying drawings and examples.Following embodiment For illustrating the utility model, but cannot be used for limiting the scope of the utility model.
Fig. 1 to Fig. 5 show a specific embodiment of the utility model:A kind of rotatable extraction for preventing tooth from falling Pincers include the first tong arm 1 and the second tong arm 2 being hinged by articulated shaft 3, and first tong arm 1 is equipped with can be around the hinge The first binding clip 4 that spindle 3 rotates, second tong arm 2 are equipped with the second binding clip 5 that can be rotated around the articulated shaft 3.In reality In tooth extraction procedure, often the mouth of patient is strutted using mouth expander first, according to the difference of extraction option, then with tools such as tweezers The corresponding mouth of patient is pushed aside outward, so both so that tooth extraction procedure becomes trouble and patient feels under the weather.This practicality Novel dental forceps only need to adjust the first binding clip 4 and second pincers when having tooth pulled out to patient according to the difference of extraction option First 5 can have tooth pulled out with corresponding tong arm at suitable angle, simply, conveniently, it is not necessary to again with tools such as tweezers by patient's Mouth is pushed aside outward.
Accommodating cavity 6 is offered on the side wall of first binding clip 4, being equipped with tooth Anti-fall in the accommodating cavity 6 fills 7 are set, the rotating control assembly for controlling corresponding binding clip rotation is equipped in first tong arm, 1 and second tong arm 2.In practical extraction In the process, during dental forceps clamps tooth, tooth anti-dropping apparatus 7 clamps tooth and fixation, after pulling up tooth When taking-up, tooth anti-dropping apparatus 7 is fixedly clamped tooth always, prevents tooth from falling into disease population since dental forceps opens In.
The tooth anti-dropping apparatus 7 includes the slide guide column 8 being set in the accommodating cavity 6, is set to the slide guide The first tooth splint 9 on column 8 and the second tooth splint 10, first tooth splint, 9 and second tooth splint 10 pass through Spring 11 is abutted against with the accommodating cavity 6.During dental forceps gradually clamps tooth, the first tooth splint 9 and second Tooth splint 10 slides into from the both sides of tooth respectively, under the action of spring 11, the first tooth splint 9 and the second tooth splint 10 Therebetween by tooth clamping, realization grips tooth.
The coaxial Double-gear that the rotating control assembly includes idler wheel 12, is sequentially connected by chain 13 with the idler wheel 12 14, first gear 14-1 and the chain 13 of the coaxial Double-gear 14 are sequentially connected, and the second of the coaxial Double-gear 14 Gear 14-2 is meshed with the semi-circle gear 15 on corresponding binding clip.When needing to carry out angular adjustment to binding clip, doctor only needs to use Hand scroll wheel 12, idler wheel 12 drives the first gear 14-1 of coaxial Double-gear 14 to rotate by chain 13, while coaxial bidentate The second gear 14-2 of wheel 14 drives the semi-circle gear 15 being meshed therewith to rotate, and semi-circle gear 15 takes corresponding binding clip to and carries out Rotation, and then realize the adjusting of binding clip angle, it is easy to operate, quick.
As a kind of preferred implementation:The top of fixed idler whell 12 is equipped on the side wall of first tong arm, 1 and second tong arm 2 Silk 16.When needing rotation roller 12 to carry out the adjusting of binding clip angle, jackscrew 16, then swing roller 12 are first unscrewed.Wait for binding clip angle After the completion of degree is adjusted, jackscrew 16 is screwed again, idler wheel 12 is fixed, and then realize the fixation to binding clip.
As a kind of preferred implementation:First tooth splint 9 is by sliding part 9-1, interconnecting piece 9-2 and clamping part 9-3 one " Z " the font clamping plate being formed by connecting, the clamping part 9-3 are equipped with the tooth receiving portion 9-4 being recessed outward and are inclined outwardly and set The guide sliding part 9-5 set.When actually being had tooth pulled out, during dental forceps gradually clamps tooth, guide sliding part 9-5 is gradually inserted at this time Enter by the gap of extraction tooth both sides, while the first tooth splint 9 and the second tooth splint 10 being driven gradually to be flared out, until Dental forceps clamps tooth, and tooth slides into tooth receiving portion 9-4 at this time, and by the first tooth splint 9 and the second tooth splint 10 Clamping.
It is preferably implemented as another kind:The idler wheel 12 is equipped with anti-slip tank.
Implement as a further preference:The articulated shaft 3 is equipped with torsional spring 17, the two side arms of the torsional spring 17 respectively with First tong arm, 1 and second tong arm 2 abuts against.On condition that an external force is not applied, torsional spring 17 is so that dental forceps keeps opening State is convenient for doctor to use in this way, convenient for operation.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model, rather than its limitations; Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: It can still modify to the technical solution recorded in previous embodiment, or be equal to which part technical characteristic It replaces;And these modifications or replacements, the utility model embodiment technical solution that it does not separate the essence of the corresponding technical solution Spirit and scope.
