Description

Nasal bone surgery guide

The present invention relates to a nasal bone surgical guide plate.

The nose is made up of nasal bones, cartilage and soft tissue. It is a part of the respiratory system and has the function of filtering/absorbing dust and impurities, and moisturizing the inhaled air. Trauma to the nose may result in a deformed appearance of the nose or even functional impairment of the nose. Generally speaking, trauma to the nose can be subdivided into chemical trauma or mechanical trauma. Chemical trauma is mainly due to irritating chemicals or burns, while mechanical trauma is mostly from car accidents, fights, occupation-related accidents or sports injuries, etc.

The conventional nasal bone surgery relies on the experience of the surgeon, with the assistance of an endoscope, and corrects by touching the touch, so it is difficult to ensure the corrective effect, and it will vary depending on the surgeon, and human errors may occur, etc. . In addition, due to the need to use an endoscope for assistance, it is easy to cause tissue damage in the patient's nasal cavity. As described above, since the conventional technique cannot ensure the corrective effect, there are problems such as long operation time and poor corrective effect.

Therefore, there is an urgent need to provide a nasal bone surgical guide to eliminate or alleviate the above problems.

In view of this, the present invention proposes a nasal bone surgery guide, which has the advantages of shortening operation time, good correction effect, reducing tissue damage in the patient's nasal cavity, or reducing human errors. In order to achieve the above objective, according to an aspect of the present invention, a nasal bone surgical guide plate includes a fixing member, a first guiding member, a second guiding member, a third guiding member, and a supporting member. The fixture may have a first surface and a second surface, the first surface of the fixture may touch the patient's teeth lightly, and the second surface of the fixture may lightly touch the patient's gums, thereby fixing the fixture In the patient's mouth, a fixing member is used to support the nasal bone surgical guide, but the present invention is not limited thereto.
