Abstract

The utility model discloses a dental elevator which comprises a handle and an elevator rod and is characterized in that a hollow through hole is formed in the elevator rod; two first elevator blades are symmetrically arranged at the end part of the elevator rod; a telescopic round rod is arranged in the hollow through hole; a second elevator blade is arranged at the end part of the round rod. According to the dental elevator disclosed by the utility model, the tissue around gingiva can be conveniently cut by use of a vibrating second elevator blade instead of hammering to increase the gap, and the operation does not need the lever force, thereby greatly improving the comfort of a patient.

Description

Dental elevator

Technical Field

The utility model relates to a medical tool, in particular to a dental elevator.

Background

In the operation process of extracting teeth, often can use the operation that the gap was extracted to the elevator and the chisel eleven increases the tooth, need use the hammering to increase the means in gap, and the hammering increases the gap and causes the patient to be uncomfortable very easily, in the operation process of extracting teeth now in addition, the elevator instrument is through using lever power, wheel axle power and wedge power to extract teeth, mainly uses lever power, uses lever power often can cause the condition emergence that the gum is torn, alveolar bone breaks.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the present invention is to provide a dental elevator to reduce or avoid the aforementioned problems.

Particularly, the utility model provides a dental elevator, it includes handle, tappet, the tappet is provided with a cavity through-hole, tappet tip symmetry is provided with two first stiff sword, be provided with the telescopic round bar in the cavity through-hole, the round bar tip is provided with the stiff sword of second.

Preferably, a vibration mechanism connected with the round rod is arranged in the handle.

Preferably, the vibration mechanism is a motor-driven linkage mechanism.

Preferably, the second straight edge is semicircular.

Preferably, the round bar has a diameter of 2 mm.

In order to solve the technical problem, the utility model provides a dental elevator. The second straight blade capable of vibrating is utilized, the peripheral tissues of the gum can be cut conveniently without using a hammering clearance increasing means, and the operation is not carried out by means of lever force any more, so that the comfort level of a patient is greatly improved.

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

The structure and the principle of a dental elevator according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a schematic view of a dental elevator according to an embodiment of the present invention; FIG. 2 is a schematic cross-sectional view of the dental elevator shown in FIG. 1; fig. 3 is an enlarged schematic view of a portion a in fig. 2. Referring to fig. 1-3, the utility model provides a dental elevator, it includes handle 1, tappet 2 is provided with a cavity through-hole, 2 tip symmetries of tappet are provided with two first sharp sword 200, be provided with telescopic round bar 3 in the cavity through-hole, 3 tip of round bar are provided with second sharp sword 300.

The handle 1 is used for holding, an adjusting switch 5 for adjusting and locking the telescopic position of the round rod 3 can be arranged on the handle, the first straight blade 200 and the second straight blade 300 are both of sheet structures, sharp cutting edges are arranged on the peripheries of the first straight blade 200 and the second straight blade 300, and when the first straight blade 200 is limited by periodontal tissues and cannot be further cut, the second straight blade 300 can be extended and fixed to further cut the deep periodontal tissues. Of course, the handle 1 may be swung and the round bar 3 may be reciprocally extended and retracted, so that the second blade 300 may repeatedly cut the periodontal tissue that is difficult to cut, thereby achieving a cutting effect.

In a preferred embodiment, a vibration mechanism 4 connected to the round bar 3 is provided in the handle 1. The vibration mechanism 4 allows the round bar 3 to oscillate transversely or longitudinally at a high frequency, thereby allowing the second pusher 300 to cut periodontal tissues more effectively.

In a preferred embodiment, the vibration mechanism 4 is a motor-driven linkage mechanism.

In a preferred embodiment, the second straight edge 300 has a semicircular shape. Therefore, when the vibration is performed, the tissue can be cut more smoothly.

In a preferred embodiment, the round rod has a diameter of 2 mm. This makes it possible to manufacture the round bar 3 and the second straight edge 300 using a high carbon steel material, and to secure sufficient rigidity and strength.

The utility model provides a dental elevator. The second straight blade capable of vibrating is utilized, the peripheral tissues of the gum can be cut conveniently without using a hammering clearance increasing means, and the operation is not carried out by means of lever force any more, so that the comfort level of a patient is greatly improved.

It is to be understood by those skilled in the art that while the present invention has been described in terms of several embodiments, it is not intended that each embodiment cover a separate embodiment. The description is given for clearness of understanding only, and it is to be understood that all matters in the embodiments are to be interpreted as including all technical equivalents which are encompassed by the claims.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes, modifications and combinations that may be made by those skilled in the art without departing from the spirit and principles of the invention should be considered within the scope of the invention.
