Abstract
[Problem to be Solved] To provide an otologic syringe needle for accurately injecting and dispersing a medical agent into an extremely small region such as a middle ear within an eardrum. is in the range of 10 to 16 degrees, and a diameter D of the needle has gauge of not less than 27. The above-mentioned constitution enables accurate injection and dispersion of a medical agent into a desired place of cartilage located in a middle ear within an eardrum. In more detail, since the needle is reduced in diameter and cutting angle compared with conventional needle, the damage of an eardrum generated when the needle is passed through the eardrum can be avoided as much as possible. Further, aches generated in general injection treatments including an injection treatment for child in an otologic treatment can be reduced.
