Description

TECHNICAL FIELD [0001] The present invention relates to a handpiece for treating rhinitis in a focused ultrasound stimulation type. [0002] RTHINITIS THERAPEUTIC HAND PIECE OF INTENSITY FOCUSED ULTRASONIC TYPE [0003]

The present invention relates to a handpiece for treating rhinitis, and more particularly, to a concentrated-type ultrasound-stimulated rhinitis treatment handpiece for subcutaneously treating each part of the nasal cavity including the mucosa of the inferior turbinate inserted into the nasal cavity.

The thickening of the inferior turbinate mucosa caused by various rhinitis causes nasal obstruction and dyspnea, and patients suffering from such symptoms are increasing. The term "rhinitis" refers to inflammation in which the nasal mucosa congestion or swelling causes secretion of serous exudate into the nasal cavity.

Surgical knife ablation, electrocautery, cryotherapy, laser ablation, and high-frequency resection are suggested as techniques for reducing the volume increased to the lower turbinate hypertrophy.

Here, in the case of hypertrophy accompanied by thickening of the inferior turbinate bones, there was a traditional inferior turbinate, a submandibular submucosal resection, and submucosal resection, which resected the bony and lateral mucosa and covered the resected mucosa. In addition, in the case of chronic hypertrophic rhinitis or allergic rhinitis with thickening of the mucous membrane, there was a technique of directly supporting the mucous membrane with a coblator, which is a type of electrosurgery generator unit that oscillates a laser or a high frequency .

However, since the conventional method for treating the enlargement of the mucous membrane is a method of directly heating the surface of the mucous membrane of the nasal cavity, there is a problem that the nasal cavity may appear after the injection, the scar can remain, and the restoration period becomes longer.

Meanwhile, since the rhinitis treatment device used in the above-described conventional treatment method generates heat during driving of the rod-shaped probe inserted into the nasal cavity, the nasal mucosa other than the treatment point can be burned and only the front nostril, There is a limit to be inserted. Therefore, it was difficult to treat the posterior nostrils with a coin duo (nasopharyngeal). Therefore, the conventional probe was manufactured to a length enough to be inserted only into the nostrils.

Further, even if the nasal insert is formed short, the nasal insert inscribed by the oscillation drive can not maintain a long time in the nasal cavity, so that the effect of treating the rhinitis is also relatively low.

The tip pipe 150 has a length and a diameter that can be inserted into the nasal cavity and forms a through hole 151 at the front end side so that the oscillating ultrasonic waves of the transducer 113 are irradiated to the outside.

The holder 110 closes the front end hole of the tip pipe 150 and constitutes a seating hole 112 for seating the transducer 113. The seating hole 112 is formed at one point of the body 111 which can face the holder 110 when the body 111 of the holder 110 is inserted into the front end hole of the tip pipe 150.

The rear end of the body 111 may be formed into a panel shape so that the front end cavity of the tip pipe 150 is divided into an upper part and a lower part of the body 111. The seating hole 112 is formed in the rear end of the body 111 And is formed so as to penetrate vertically.

The transducer 113 is seated and fixed in the seating hole 112 so that the front end 115 and the bottom of the seating hole 112 are arranged to maintain a space. That is, the transducer 113 is disposed at the front end 115 of the seating hole 112 so that the upper space and the lower space 116 communicate with each other.

As a result, the front end hollow of the tip pipe 150 around the transducer 113 is communicated only through the front end 115 of the seating hole 112. Subsequently, the transducer 113 oscillates an ultrasonic wave having a frequency specified by the supply current, and the transducer 113 of this embodiment can oscillate the ultrasonic wave. For reference, the holder 110 of the present embodiment may include a pin-shaped holder 117 for supporting the transducer 113, and the transducer 113 may be fixed by various seating means.
