Expanding treatment device for nasal cavity and paranasal sinuses

An expanding treatment device for a nasal cavity and paranasal sinuses, the expanding treatment device comprising:

• a nasal insertion member inserted into an anterior portion of the nasal cavity of a human body;
• a treatment device main body member connected to the nasal insertion member, and having an inside that communicates with an inside of the nasal insertion member;
• and
• an expanding treatment member penetrating the nasal insertion member and the treatment device main body member together while being connected to the treatment device main body member, and having an end portion penetrating the nasal insertion member and expanded outward by air supplied from an outside,
• wherein the treatment device main body member is connected to the nasal insertion member such that a connected position is variable, and as the connection position of the treatment device main body member with respect to the nasal insertion member varies, a length of a portion of the expanding treatment member penetrating the nasal insertion member and connected to the treatment device main body member is variable, and
• since the length of the portion of the expanding treatment member that penetrates the nasal insertion member is variable, a position of an end portion of the expanding treatment member with respect to the nasal insertion member is also variable, so that the end portion of the expanding treatment member expanded by air applied from the outside is able to selectively stimulate at least one of a portion of the nasal cavity that is relatively deeper than a portion into which the nasal insertion member is inserted, a paranasal sinus, a sphenoid bone, and a temporomandibular joint.
