Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

In this embodiment, in order to clarify the interconnection of the characteristic configurations, detailed descriptions of the configurations that are the same as those of the prior art described above will be omitted.

A characteristic of this embodiment is that the tooth protection member 200 is manufactured by injection molding integrally with the guide tube 300 of the body 10.

Since the body 10 including the guide tube 300 is made of a material such as plastic, and the tooth protection member 200 is made of a material such as silicon with elastic force, the materials of both components are different from each other. It is formed of different materials, and by manufacturing each component formed of these different materials by injection molding as one piece, the manufacturing process can be simplified and productivity can be significantly increased.

The guide tube 300 and the tooth protection member 200 are integrated by injection molding, so that when the patient bites the tooth protection member 200 of the mouthpiece, the tooth protection member slides away from the guide tube 300. prevent.

In addition, when sterilizing products injection molded from different materials, the sterilization time is significantly reduced, and when the conventional tooth protection member 20 and the guide tube 30 are manufactured separately and then combined, the tooth protection member 20 It has the effect of fundamentally blocking the propagation of bacteria into the microspace of the contact area between the and the guide tube (30).

In the following embodiments, a structure that can maximize the wearing comfort and imaging efficiency of the endoscope will be described.

Since the width (ℓ) of the through hole 11 formed by the conventional mouthpiece guide tube 30 is formed to be long, the through hole 11 has an oval structure that is elongated in the left and right directions, so that the endoscope tube penetrates. It frequently occurs that the sphere 11 flows while shaking. Therefore, this embodiment is intended to provide a structure to solve the problem that the imaging efficiency of the endoscope camera is significantly reduced due to the endoscope shaking due to the conventional structure, and the patient is uncomfortable to wear.

Figure 2 is a schematic cross-sectional view showing that the cross-section of the through hole of the guide tube of the present invention has a structure close to circular.

As shown, a feature of this embodiment is that the width (L) of the guide pipe 300 of this embodiment is shorter than the width (L) of the conventional guide pipe 30.

In addition, compared to the outer surface curvature (r) of the conventional guide tube 30, the outer surface curvature (R) of the guide tube 300 of this embodiment is smaller, so that the cross-section has a structure close to a circular shape.

If the width (L) of the guide tube 300 of the mouthpiece having this structure is '0', it becomes a perfect circle, and when it becomes a perfect circle, the bite of the teeth decreases when the protective member is bitten after insertion into the patient's mouth. The ratio of the width (L) of the guide tube (300) of the mouthpiece to the outer curvature (R) of the guide tube is preferably 1:2 to 3.

Compared to the prior art, the guide tube 300 has a shorter width (L) and a structure with a smaller curvature (R), so the flow of the endoscopic tube inserted into the through hole 110 is minimized, thereby improving the imaging efficiency of the endoscopic camera. It has actions and effects that can be maximized.

In addition, since the guide tube 300 has a short width (L) and a small curvature (R), it minimizes the opening of the patient's jaw in the direction of both molars when the mouthpiece is inserted into the patient's oral cavity. Thus, it can have the action and effect of maximizing the patient's sense of stability and wearing comfort.

In the following embodiments, a structure that can maximize the patient's convenience in wearing the mouthpiece will be described.

Figure 3 is a plan view of the guide tube and tooth protection member and a partially enlarged view of the projections.

As shown, this embodiment is characterized in that an arc portion 310 is provided at the end of the guide tube 300 facing the oral cavity.

Another characteristic is that the protrusion 210 formed on the outer surface of the tooth protection member 200 is provided in a structure corresponding to the patient's tooth shape (tooth shape) imaginary line (T).

Since the guide tube 300 or the protrusion 210 having this structure forms a curvature corresponding to the patient's tooth shape, the guide tube 300 or the protrusion 210 that is bitten by the patient's teeth during the endoscopic procedure is shaped like the tooth. Since it is located in a position corresponding to the virtual line (T), it has the action and effect of maximizing the patient's convenience and stability in wearing the mouthpiece.

In the following embodiments, a structure that can minimize frictional resistance between the mouthpiece and the endoscope tube will be described.

Figure 4 is a cross-sectional view of a guide tube provided with a round portion.
