Abstract

Dual-beak dental forceps system comprises dual-beak dental forceps and the rubber finger sleeve that matches, and compares with single-beak type dental forceps in the past, has overcome no support point, tooth around easy-breaking-tooth or the damage, and wound reaches shortcomings such as operation easier is big greatly.Its technical characterictic is: two pincers are the upper end one external beak, and lower outer edge can rotate around institute's anchoring forceps handle.Two outer beaks include the interior beak that there is torsion spring a pair of centre.Interior beak be fixed in by axle have lower outer edge pincers last.Outer beak inner face all has an inclined guide rails that can supply interior beak to slide therein.Pincers are tightening up a half, and inside and outside beak is all closed, interior beak folder tooth, and outer beak props up the periodontal osseous tissue; Continue to tighten up the pincers handle, then interior beak clamps also to be slided behind guide rail, and tooth is pulled out.Rubber finger sleeve is similar to dental forceps outward, in order to cover dental forceps, is disposable use, can simplify disinfectant program.

Description

Dual-beak dental forceps system

The present invention relates to a kind of dental instruments, specifically, is Dual-beak Ba Ya system.It comprises Dual-beak Ba Ya and rubber finger sleeve.From exodontia invention so far, the employed tooth that pulls out is the single-beak type structure.Promptly similar with Dian Gong , have only Yi Dui beak, can be referred to as single-beak type Ya .As HEIMANNW (PAT-NO:DE3026151) Shang Ya and FREUDE W (PAT-NO:DE3320844) Xia Ya .Its exodontia mode is that:Kao clamps tooth, and Bing swings back and forth, and makes odontoseisis, in swing tooth is pulled up.Its shortcoming is:(1) Wei Insurance is big:it is right that fracture of tooth, Huo Damage wound easily takes place in swing

Tooth and adjacent teeth, (2) Chong hinders big, and by the swing of tooth, in the time of odontoseisis, tooth surrounding bone Group knits and is squeezed, and alveolar bone is subjected to Chong hinders, and it is big that tooth groove Waterloo becomes, and is unfavorable for pulling out tooth Waterloo healing.(3) reach can Jin Kuai Shake pine tooth for strength, the rate request of the moving tooth of operation easier Da ， Shake, but unlikely fractureing.This just needs hundreds and thousands of De Ti Experience, comprises the tooth De Ti Experience that fractures.(4) efficient is low, and labor intensity is big: for preventing fracture of tooth, amplitude of fluctuation Xu Zhu Getting increases, and a firm tooth be pulled out needs suitable De Shi Inter and muscle power.

The present invention provides a kind of safety and reliability, and Chong hinders little, and the instruments for tooth extraction that efficient is high becomes exodontia Ji Intraoperative and dentist Light easily lifted fast and reliable; Concerning patient, shorten Ya Chi with painful Shi Inter locked in a stalemate.

The application value of this invention and advantage:

1. Dual-beak Ba Ya system exodontia Shi Ya integral body does not need swing, has avoided hindering adjacent teeth and right

The possibility of tooth.

2. that wrecks may reduce or eliminate, and the vertical Shaft of the relative tooth of power of single beak tooth exodontia is horizontal or oblique, the tooth frangibility, and the power of Dual-beak tooth is longitudinally.

3. the Chong wound is little, is beneficial to healing, when Dual-beak Ba Ya system has tooth pulled out, generally need not swing, and tooth is to not bump and the extruding of surrounding bone wall.

4. improve and pull out tooth hands Intraoperative efficient, Inter when shortening exodontia:utilize Dual-beak to pull out tooth system and can exempt to remove Shake pine Inter that tooth takes.

5. reduce the exodontia difficulty:with the single-beak type tooth that Now has, Shake pine tooth is a high job of difficulty, and both having made is to have Feng Fu can not guarantee the tooth that do not fracture fully through the dentist of Experience, and Dual-beak pulls out tooth system and do not need Shake moving, or it is moving to subtract few Shake.

6. processing ease:than single-beak type Ya easy operating.

Dual-beak Ba Ya system comprises rubber finger sleeve and Dual-beak Ba Ya , and rubber finger sleeve covers Ya , can increase frictional force, clamps tooth, simplifies disinfectant program simultaneously.

The primary structure of Ba Ya is:

* by beak (7,9) in Shaft (a 10) Even couple together, be used to clamp tooth;

* Yi is (1) and Er (2);

* a pair of upper and lower outer beak (16,6) is used to prop up periodontal Gu Group and knits;

* going up outer beak (16) Yu Yi is a Gang body;

* (6) Tong Guo Shaft (5) and Er are (2) Even connect, and Bing Ke Rao Shaft (5) rotates for lower outer edge;

* ((13) Even meet Bing Ke Rao Shaft (13) and rotate 6) Tong Guo Shaft Yi with lower outer edge (1);

* upper and lower outer beak (16,6) is gone up Fen other Let and is led Rail (14,19), be used to guide upper and lower interior beak (9,7), make upper and lower interior beak after clamping the tooth that will pull out, can lead Rail (14 in the edge, 19) slide backward with respect to outer beak (16,6), thereby tooth is pulled out.

Details carefully schemes explanation (content of invention)

Ginseng See Fig. 1, Dual-beak Ba Ya comprises two parts on the whole:first is 1 based on Yi ; Second portion be based on Er 2, beak 9 in going up, down in beak 7 and torsion spring 8 Yong Yi Pins 10 Gu Ding Zai on 2, Tong Shi 2 and lower outer edge 6 usefulness posts 5 tight, but turn.Second portion and the Tong Guo Pins of first 13 Jin, Even are connected together. is last two sweeps (21,22) in order to hang rubber finger sleeve.Figure 1A be Xian Shi 1 2, the profile that lower outer edge 6 usefulness posts 5 Even connect.In Fig. 1, can by with Pins 4 with torsion spring 3 solid fixed 1 on, two are opened 1,2 minute, outer beak 6,16 Zhang are opened.Stage clip, 11 is put into hole 15, stage clip 11 hold-down columns 12.Fig. 1 C has shown the relation of

interior beak

7,9 and outer beak 6,16.

The, Ji of first of figure 2 Shi is 1, and its head has the lead Rail of a skewed slot 14 as beak 9 in last, and Fig. 2 B has shown the shape of leading Rail 14.Outer beak 16 has a thread form groove on the front portion.Endoporus 15 is put into stage clip 11, with hold-down column 12.

Figure 3 Shi are 2 the second portion of main body.Beak 9 in going up, down in beak 7 and torsion spring 8 You Pins 10 Gu Ding Zai on 2.Lower outer edge 6 (has a thread form groove) tight by post 5 Yu 2 , can utilize torsion spring 8 will go up interior beak 9 and separate with down interior beak 7.Also have the convex that through hole 17 is arranged on the lower outer edge 6, spacing hole 20 is arranged on 2 at as stopping means.The head of lower outer edge also has a tipper 19, as the Rail that leads of down interior beak 7.The part of folder tooth of

beak

9,7 is all made thread form (Fig. 3 A) in upper and lower, go up outer beak 16 and lower outer edge 6 interior lead Rail 14,19, a very little inclination angle is arranged, be convenient to tooth is clamped.

Post 5 is that lower outer edge 6 He are 2 De Zhuan Shaft, Pins 13 first and second portion De Zhuan Shaft.

When afterburning, torsion spring 3 is compressed 1,2 for ginseng See Fig. 4, Dang Gei , and second portion Rao Shaft 13 closes two couples of beak Tong Shi Closed with respect to first's rotation,

interior beak

9,7 clamping teeth, and torsion spring 8 is compressed.

(Fig. 5) external beak props up dentale when continuing reinforcing, and rotates 2 with respect to lower outer edge 6 around Shaft 5, and Bing and clamp the interior beak 9 of going up of tooth to 2 Even together, and down interior beak 7 and torsion spring 8 slide backward with respect to first, can reach to limit the position, and tooth is pulled out.Simultaneously, post 12 is moving Xiang Hou Roll in company with 2.After power was removed, torsion spring 3 was opened to 1,2 minute, post 12 with Roll return original position, outer beak 16,6 Zhang open,

interior beak

9,7 Zhang under the effect of torsion spring, 8 opens, and sets back.

Fig. 6 is the rubber finger sleeve shape, and it is disposable use, its role is to, and simplifies disinfectant program; Increase frictional force, make tooth be difficult for slippage; Simultaneously, also Ke Jian Light hinders Ya Gu Group Zhi De Damage.Two groove parts of rubber finger sleeve are clipped in one pair, the Inter of beak down, when interior beak is clamped tooth, slide backward, with outer beak have one apart from the time, this splits not cause rubber finger sleeve.Its underpart is drawn back, in the

bending

21,22 of Gua Zai handle.
