Description

Devices for installing dental mirrors

technical field

The present invention relates to the field of tools and accessories related to dental surgery, in particular, the invention related to dental mirrors.

Background technique

The dental mirror is an important instrument for the user. During the dental operation, the user observes the subtle movements in the patient's oral cavity through mirror reflection, so as to control the purpose of treatment.

Various dental mirrors of the prior art are constructed of an inclined reflective surface mounted on the end of a handle. Some similar dental mirror assemblies have an integral steel structure, and at the end of the handle, the smooth surface of a metal sheet forms the mirror.

The use of these familiar dental mirrors during the operation is a very careful and cumbersome process. The surgeon must hold the entire dental mirror handle assembly, and to do this he must use the handle with one hand, and at the same time he has to use it. The other hand manipulates surgical tools. In this way, both of his hands were occupied during the operation, and as a result, he could not perform other operations at the same time, such as suctioning water and debris. Therefore, the surgeon must take the dental tool out of the oral cavity, then take another tool that is needed, and put it into the oral cavity to continue the operation.

Another inconvenience of the dental mirrors of the prior art is the congestion caused by the dental mirrors in the patient's mouth, because generally speaking, there is basically always a suction needle tip left there to occupy the oral cavity. space.

Someone has proposed a device for installing a dental mirror, comprising a dental mirror support body (seeing for example patent US-A-4 521 185, WO-95/15113, US-A-5 230 622 or US-A-1500 798).

These known devices are mounted on the outer edge of the suction needle tip, with the result that they still congest the oral cavity.

We also know a kind of dental mirror support body by patent US-A-3 928 912 simultaneously, and it has a head that places mirror surface, and has suction hole, and the main body structure of support body has a ventilation groove. This device is complicated, expensive and greatly reduces the effectiveness of the suction. The head of the support is actually a part of the suction needle head.

Contents of the invention

The invention provides a device for installing a dental mirror, which can be combined with other instruments used by the user in the oral cavity during the operation, so that the user can control and observe the ongoing work conveniently and freely, And can also use other equipment at the same time. It also facilitates the user's ability to diagnose what needs to be done before implementing therapeutic measures.

For this reason, the purpose of the present invention is to propose a dental mirror mounting device, which contains a dental mirror support body and is installed as one with a suction needle head, and its feature is that the above-mentioned support body is composed of a separate part Composition, the part contains a main body part, the main part is pushed into the inside of the above-mentioned suction needle tube head and installed in it to determine the size of the main part, the above-mentioned main part extends a section of mirror support body, and the support body is composed of The direction of the longitudinal axis of the main body is inclined outwards.

According to the device of the present invention, no matter for the user or the patient, it will bring significant advantages. These advantages are reflected in the integrated design of the dental mirror and the suction needle head, so that the operation of the suction needle head and the placement of the dental mirror Synchronous and consistent, it not only avoids the uncomfortable feeling of the patient due to the congestion of the oral cavity, but also prevents the aspiration needle from being blocked.

The support mentioned above is preferably made of synthetic material. Another advantage is that said section of mirror support consists of two inclined fingers extending into a corrugated sheet, said main body having a protrusion perpendicular to the center of said corrugated sheet shaft, the dental mirror is fixed on two inclined fingers, its shank rests on the corrugated lamina and maintains its position when the main body part is pushed into the interior of the above-mentioned suction needle head and fits in it .

Description of drawings

Fig. 1 is the structural representation of dental mirror mounting device of the present invention;

Fig. 2 is a side vertical projection view of the dental mirror mounting device described in Fig. 1;

Figure 3 is a rear view of the dental mirror mounting device described in Figures 1 and 2;

Figure 4 is an exploded view of a combination described in the present invention being installed on the aspiration needle head.

Detailed ways

The following is an example, reading this description will help to understand the invention, the illustration of this example is in the attached drawing:

In the preferred embodiment of Figs. 1 to 4, the mounting device or dental mirror support 1 is made of a single part, which contains a main structure of a corrugated thin layer 2, which is wave-shaped; a protrusion 3, which is perpendicular to the central axis of the corrugated thin layer 2 above. The shape and size of the corrugated thin layer 2 and the protrusion 3, that is, the size of the main body part that constitutes the installation device, is just the size that this main body part can be put into the inside of the suction needle tube head (the suction needle tube head is shown in Fig. 1 to Fig. 1 ). 3), the corrugated sheet 2 and the sides 4 of the protrusions 3 are under pressure inside the aspiration needle head. The main structures 2, 3 can also be forced into and installed inside the suction needle head 9 through elastic deformation, and remain in this position without moving and without affecting the suction.

In a position opposite the protrusion 3, the body parts 2, 3 are extended by two oblique fixed clips, which are external to the suction needle head and which can hold a dental mirror 6 (Fig. 4) , and keep it at an angle and axis. In the groove 8 of the corrugated thin layer 2, the handle 7 of the dental mirror 6 is fixed therein, like this, after the support body 1 is pushed into the suction needle head 9, the dental mirror 6 will remain still along the axis.

Claims (3)

1. The dental mirror installation device is a device that contains a support body (1) of a dental mirror (6) and is integrated with a suction needle head (9). It is characterized in that the above-mentioned support body (1) It is composed of a single part, which contains a main body part (2, 3), which is pushed into the interior of the above-mentioned aspiration needle tube head (9) and installed therein to determine the size of the main body part, the above-mentioned A segment of mirror support body (5, 5) is extended from the main body part (2, 3), and the support body is inclined outward from the longitudinal axis direction of the main body part (2, 3). 2. The device according to claim 1, characterized in that said support (1) is made of synthetic material. 3. The device according to claims 1 and 2, characterized in that said one section of mirror support (5, 5) is made of two inclined fingers extending into a corrugated thin layer (2), The above-mentioned body part has a protrusion (3), which is perpendicular to the central axis of the above-mentioned corrugated thin layer (2).
