Description

Technical Field

[0001] The invention relates to the technical field of nasal bone correction equipment, and in particular to a nasal septum rongeur. Background Art

[0002] The nasal septum is located between the left and right nasal cavities, and is composed of the vertical plate of the ethmoid bone, the vomer bone, and the nasal septum cartilage, with the surface covered by mucosa. The nasal septum of a normal person is rarely completely in the middle, and most of them are slightly deviated. Due to the structural deformity of the nasal septum caused by certain factors during its development, it is morphologically deviated to one or both sides, or partially protrudes, which can affect the physiological function of the nasal cavity and cause the sharp protrusions of the nasal septum to be called spinous processes or calcarine processes, and the long protrusions are called ridge processes. If the nasal septum cartilage protrudes into the nasal vestibule, it is called anterior dislocation of the nasal septum cartilage. Therefore, doctors need to use nasal septum rongeurs for treatment.

[0003] Most existing nasal septum rongeurs have an angle of 120°, which is not suitable for biting the front end of the nasal septum. The surgeon needs to adjust the angle by holding it. The bone at the front end of the nasal septum is thick, which makes it very inconvenient for medical staff to bite the bone and is time-consuming and laborious.

[0004] Therefore, there is an urgent need for a nasal septum rongeur to solve the above-mentioned problems. Summary of the invention
