Title (EN) SMALL-SIZED AIR PRESSURE MEDICAL APPARATUS AND ADAPTOR THEREOF
(FR) APPAREIL MEDICAL A PRESSION D'AIR DE PETITE DIMENSION ET SON ADAPTATEUR
(KO) 소형 공압 의료 장치 및 그 어댑터
Abstract:
(EN) The present invention relates to an air pressure turbine handpiece which is commonly used today. More specifically, the air pressure turbine handpiece of the present invention reduces noise substantially while providing enough torque for a medical bur. The air pressure turbine handpiece of the present invention comprises: a housing including a chamber; a hub installed in the housing and rotating axially; and a plurality of disks which are perpendicular to the axis and connected to the hub. The housing includes: a hole formed along the axis to accept the bur; and an input port formed to guide the fluid to flow into the chamber in a direction substantially tangential to the axis. The hub includes an axial channel to selectively mesh with the bur. The force caused by the boundary layer effect between the disks and the fluid allows the hub and the bur to rotate axially.
(FR) L'invention concerne une pièce à main à turbine à pression d'air aujourd'hui d'usage courant. Plus précisément, la pièce à main à turbine à pression d'air selon l'invention réduit le bruit sensiblement tout en produisant un couple suffisant à une fraise médicale. Ladite pièce à main selon l'invention comprend: un logement comportant une chambre; un moyeu installé dans le logement et tournant de manière axiale; et plusieurs disques qui sont perpendiculaires à l'axe et reliés au moyeu. Le logement comporte: un trou formé le long de l'axe de façon à accepter la fraise; et un port d'entrée formé de manière à guider le liquide s'écoulant dans la chambre dans une direction sensiblement tangentielle à l'axe. Le moyeu comporte un canal axial pour sélectivement être en prise avec la fraise. La force due à l'effet de la couche limite entre les disques et le liquide permet au moyeu et à la fraise de tourner de manière axiale.
(KO) 본 발명은 현재 일반적으로 사용되는 추진 터빈 공압 핸드피스와 관련하여, 실질적인 소음 감소를 나타내는 반면 의료용 버에 대해서는 충분한 토크를 제공하는 장치를 제공하고자 하는데 그 목적이 있다. 이를 위해 본 발명은, 챔버를 구비한 하우징과, 축회전하도록 하우징 내에 설치되는 허브와, 상기 축에 실질적으로 직교하며, 상기 허브에 연결되어진 복수개의 디스크를 포함하되, 상기 하우징은 버를 수용하기 위해 축을 따르는 단부홀을 형성함과 아울러 유체가 축에 대해 실질적으로 접선방향을 이루며 챔버로 유입되도록 안내하는 입력포트를 형성하고, 상기 허브는 버와의 선택적인 맞물림을 위한 축방향 채널을 형성하며, 상기 복수개의 디스크들과 유체 사이에서의 경계층 효과의 작용력은 허브와 버가 축 회전하도록 하는 것을 특징으로 하는 소형 의료 장치가 제공된다.
