Abstract
The utility model provides a dental elevator which comprises an elevator handle (1) and an elevator rod (2), and is characterized in that an elevator edge (3) is arranged on the top end of the elevator rod (2); a groove is formed in the abdomen of the elevator edge (3); a bulge which corresponds to the groove is formed in the back of the elevator edge; the top end of the elevator edge (3) is in a three-tooth shape; the tooth height in the middle is 1-1.5mm; the tooth height on two sides is 0.4-0.9mm. The dental elevator is simple in structure and convenient to use and is particularly suitable for allowing extracted teeth to separate from a tooth socket of a patient during tooth extraction, so that pain of tooth extraction to the patient is reduced, and the labor intensity of a surgical operator is lightened.
Description
Technical field
This utility model relates to teeth groove surgery instruments for tooth extraction, relates in particular to a kind of dental elevator.
Background technology
Dental elevator has another name called tooth sledge, it is the conventional medical equipment of pulling out patient's cacodontia of a kind of clinical oral, it uses the attachment relationship between " lever principle, wheel shaft principle and wedge mechanics principle " sledge pine root of the tooth and the alveolus in physics, the body that makes to be had tooth pulled out dislocation, to assist " dental forceps " to implement fast, effortlessly treatment clinical course.
Adhering mode between tooth body and alveolus is periodontal ligament, this ligament is tough and tensile and fine and close, under animation, can tolerate the impulsive force of 30-50 kilogram, thereby conventionally need to auxiliaryly prize the annexation between loose root of the tooth and alveolus in dental elevator before using dental forceps to dislocate, root of the tooth and alveolar bone could be dissociated; Particularly for " impacted tooth, malposed tooth " and " undesirable root, be completely cured " non-use dental elevator and can not from tooth socket, root of the tooth be peeled off.
Dental elevator is that all-metal forms apparatus, and profile is made up of three parts: endure handle, tappet and endure sword.Very sword is the key component of instruments for tooth extraction and the conversion of tooth body dislocation power, the very sword end of the dental elevator of current clinical use is circular arc, the very sword of this form in use has the following disadvantages: (1) is in extraction, very difficulty between sword wedging root of the tooth and alveolus, causes the not enough luxated tooth that affects of moment for the follow-up application of force lacks fulcrum; (2) the very not enough and easily slippage of coefficient of friction between sword and root of the tooth, makes the power that prizes of lever can not be transferred to stably periodontal and forms dislocation power, thus impact exodontia effect; Therefore, be necessary the form of the blade of improveing traditional dental elevator.
Utility model content
For solving the problem existing in background technology, this utility model provides one to be particularly useful in exodontia and has been dislocated from patient's alveolus by exodontia tooth, to reduce the dental elevator of extraction to patient's the pain of injury and the person's labor intensity that alleviates operation technique.
Its concrete technical scheme is as follows:
A kind of dental elevator, comprise very handle (1), tappet (2), it is characterized in that: described tappet (2) top is provided with very sword (3), very sword (3) abdominal part is provided with groove, back has and groove projection accordingly, very sword (3) top is three dentations, and middle tooth depth is 1-1.5mm, both sides tooth depth 0.4-0.9mm.
This utility model divides and redesigns profile blade very, and very sword is arc, is designed to zigzag at sword end very, and profile is " three flute profiles " (middle tooth depth 1-1.5mm, the each high 0.4-0.9mm of both sides tooth).This dental elevator in use, " concave surface " of its arc can make dental elevator slide between wedging root of the tooth and alveolus along the column of root of the tooth, when the very sword of wedging is during at periodontal spaces double swerve, jagged blade isolates the connection ligament of periodontal fast, stumbles for luxated tooth has dissociated to arrest; In the time that dental elevator uses lever force to prize luxated tooth, very the tooth of sword end is fastened on root surface with anti-slip (principle is for having increased coefficient of friction) under the promotion of power, the now power arm application of force taking alveolar ridge as fulcrum, is easy to root of the tooth to prize from tooth socket pine and makes its dislocation.
The beneficial effects of the utility model are.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 endures blade to divide close up view (sword head is groove shape, and there are three outstanding teeth on top) in this utility model;
Wherein endure handle-1, tappet-2, endure sword 3.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is further described.
A kind of dental elevator, comprise very handle (1), tappet (2), it is characterized in that: described tappet (2) top is provided with very sword (3), very sword (3) abdominal part is provided with groove, back has and groove projection accordingly, very sword (3) top is three dentations, and middle tooth depth is 1-1.5mm, both sides tooth depth 0.4-0.9mm.
This utility model divides and redesigns profile blade very, and very sword is arc, is designed to zigzag at sword end very, and profile is " three flute profiles " (middle tooth depth 1-1.5mm, the each high 0.4-0.9mm of both sides tooth).This dental elevator in use, " concave surface " of its arc can make dental elevator slide between wedging root of the tooth and alveolus along the column of root of the tooth, when the very sword of wedging is during at periodontal spaces double swerve, jagged blade isolates the connection ligament of periodontal fast, stumbles for luxated tooth has dissociated to arrest; In the time that dental elevator uses lever force to prize luxated tooth, very the tooth of sword end is fastened on root surface with anti-slip under the promotion of power, and the now power arm application of force taking alveolar ridge as fulcrum, is easy to root of the tooth to prize from tooth socket pine and makes its dislocation.
