0-135
0, very sword (3) back is provided with groove.Very the angle between sword (3) and tappet (2) is 105
0-115
0, very sword (3) inner side abdominal part is provided with groove.Described beak shape is endured the long 15-25mm of being of processus coracoideus of sword (3).This utility model is simple in structure, easy to use, is particularly useful for to pull out lower molar root fracture " being completely cured " in tooth socket and because of bad " undesirable root " causing of corona dental caries, and the person that makes operation technique can be fast, take out and remain in the root of the tooth in tooth socket accurately.
Description
Technical field
This utility model relates to teeth groove surgery instruments for tooth extraction, particularly a kind of root elevator.
Background technology
Clinical oral is rolled over because exodontia causes root, is completely cured and is trapped in tooth socket, or because the bad rear undesirable root forming of dental caries is retained in tooth socket, all need it in tooth socket, to take out, otherwise human body can exist and cause discomfort with foreign body.Take out residual root of the tooth multiselect and wedge the gap between root of the tooth and tooth socket with dental elevator, use wheel shaft principle or lever force to be prized, traditional yet " root elevator " has the following disadvantages textural, it is consuming time that the person that often causes operation technique sled is got undesirable root effort, and patient is also because often the time feels exhausted in mouth-open.
(1) " straight-bar root elevator " due to sword very with tappet in same axis, make blade very when the gap of wedging root of the tooth and tooth socket wall, the near middle adjacent teeth tooth of the root that is subject to have tooth pulled out in advance blocks and insert can not be (because of from existing one approximately 90 between occlusion of dentition plane and adjacent teeth gap
0while angle), causing sled to endure root of the tooth, have no way of putting forth effort; (2) " curved root elevator " is although have tappet and endure the bent angle between sword, to allow the very beak portion of sword to insert the gap between root of the tooth and tooth socket, but this pair of very groove of sword beak portion is positioned at beak side, also can only be from its cheek side or the tongue side wedging application of force when sled is got residual root of the tooth, according to the configuration of tooth socket and biomechanics, cheek side and the levum plate of tooth socket are thin, and this is unfavorable for getting and adhering to firm root of the tooth as balance pivot sled; (3) clinical sled is got a kind of " the triangle dental elevator " in addition of root of the tooth, this dental elevator not only very sword beak portion short, make the periodontal spaces that stretches into dark in limited and affect outside the application of force, and the point of application is also in cheek side or the tongue side of root of the tooth, and what cut application is that the efficiency of wheel shaft principle, its displacement is also poor compared with curved elevator.Thereby design a efficient, laborsaving, exodontia " root elevator " safely, be the needs of clinical oral medical treatment.
Utility model content
For solving the problem existing in background technology, this utility model provides a kind of root elevator, and its concrete technical scheme is as follows:
A root elevator, comprises very handle (1), and tappet (2), is characterized in that: described tappet (2) top is provided with very sword (3), and described very sword (3), with respect to tappet (2) bending, is beak shape, and very the angle between sword (3) and tappet (2) is 125
0-135
0, very sword (3) back is provided with groove.
Angle between described very sword (3) and tappet (2) is 130
0.
A root elevator, comprises very handle (1), and tappet (2), is characterized in that: described tappet (2) top is provided with very sword (3), and described very sword (3), with respect to tappet (2) bending, is beak shape, and very the angle between sword (3) and tappet (2) is 105
0-115
0, very sword (3) inner side abdominal part is provided with groove.
Angle between described very sword (3) and tappet (2) is 110
0.
Described beak shape is endured the long 15-25mm of being of processus coracoideus of sword (3).
This utility model divides and carries out configuration design again blade very, very the styma of sword and traditional metal dental elevator are with value, be not all and partly redesign enduring beak, design concept and know-why are as follows: 1. this dental elevator is exclusively used in and pulls out being completely cured and undesirable root of lower molar, and the suitable especially sled to lower jaw wisdom teeth root of the tooth is got.2. tappet divides and is designed to " beak shape " with blade very, the long 15-25mm of processus coracoideus, and minute A.B. amphitypy, endures between the processus coracoideus of sword and tappet and has angle (A. type 125
0-135
0, B. type 105
0-115
0), cheaply to endure sword when sled is got root of the tooth, successfully insert in root week gap.3. the groove of A. type processus coracoideus is designed in the very dorsal part of sword, aim at the nearly middle root of the tooth of sled and design, after enduring the mesial surface wedging periodontal spaces of beak along mesial root, tappet and very handle are power arm, the wall of tooth socket forms strong fulcrum under the support of adjacent teeth root, in order to prize the de-mesial root in nest wall that is fixed on; B. the groove of type processus coracoideus is designed in the very veutro of sword, aim at sled middle root of the tooth far away and design, after enduring the distal surface wedging periodontal spaces of beak along distal root, tappet and very handle are power arm, on tooth socket wall, form fulcrum, this fulcrum, owing to there being the sclerotin of retromolar triangle to strengthen making drag to increase, becomes very easy thereby middle root of the tooth far away is dislocated.
The beneficial effects of the utility model are:
Be particularly useful for and pull out lower molar root fracture " being completely cured " in tooth socket and because of bad " undesirable root " causing of corona dental caries, the person that makes operation technique can be fast, take out and remain in the root of the tooth in tooth socket accurately.
