Abstract
(EN)
An acetabular cup detaching apparatus for an artificial hip joint, according to an embodiment of the present invention, comprises: a body part that rotates with power transmitted thereto; and a cutting part brought in close contact with the inner circumferential surface of the acetabular cup and rotating together with the body part to cut the surface of the acetabular cup. According to the present invention, an operation can be easily performed by rotating a blade, together with a rotary shaft part, along the outer circumferential surface of the acetabular cup in the radial direction of the acetabular cup through electric control, which makes it possible to rapidly and accurately detach the acetabular cup from an acetabular bone irrespective of an operator's skill. In addition, it is possible to prevent damage to the blade in advance, minimize damage to an acetabular bone, and accurately detach only the acetabular cup from the acetabular bone by forming a support cup and the blade in sizes corresponding to the outer and inner circumferential surfaces of the acetabular cup and gradually cutting the acetabular bone part, to which the acetabular cup is attached, by rotating the blade at a predetermined angle according to predetermined steps.

Un mode de réalisation de la présente invention concerne un appareil de détachement de cupule acétabulaire pour une articulation artificielle de la hanche, comprenant : une partie de corps qui se met en rotation avec l'énergie transmise à celle-ci ; et une partie de coupe amenée en contact étroit avec la surface circonférentielle interne de la cupule acétabulaire et se mettant conjointement en rotation avec la partie de corps pour couper la surface de la cupule acétabulaire. Selon la présente invention, une opération peut être facilement réalisée en mettant en rotation une lame, conjointement avec une partie d'arbre rotatif, le long de la surface circonférentielle externe de la cupule acétabulaire dans la direction radiale de la cupule acétabulaire à travers une commande électrique, qui permet de détacher rapidement et avec précision la cupule acétabulaire d'un os acétabulaire indépendamment d'une compétence de l'opérateur. En outre, il est possible de prévenir les dommages à la lame à l'avance, de réduire au minimum les dommages causés à un os acétabulaire, et de détacher avec précision uniquement la cupule acétabulaire de l'os acétabulaire grâce à la formation d'une cupule de support et la lame dans des tailles correspondant aux surfaces circonférentielles interne et externe de la cupule acétabulaire et à la découpe progressive de la partie d'os acétabulaire, auquel la cupule acétabulaire est fixée, en mettant en rotation la lame à un angle prédéterminé selon des étapes prédéterminées.

본 발명의 실시예에 따른 인공고관절용 비구컵 탈거 장치는 동력을 전달받아 회전하는 바디부, 그리고 비구컵의 내주면에 밀착되고 상기 바디부와 함께 회전하여 상기 비구컵의 표면을 절삭하는 커팅부를 포함한다. 본 발명에 의하면, 전동제어를 통하여 블레이드를 회전축부와 함께 비구컵의 반경 방향으로 회전시킴과 동시에, 비구컵의 외주면을 따라 회전시킴으로써, 시술이 용이하여 시술자의 숙련도와 상관없이 신속하고 정확하게 비구컵을 비구골로부터 탈거할 수 있다. 또한, 지지컵 및 블레이드를 비구컵의 외주면 및 내주면에 대응되는 크기로 형성하고, 블레이드를 미리 정해진 단계별로 소정의 각도로 회전시켜 비구컵이 부착된 비구골 부위를 점진적으로 절삭함으로써, 블레이드의 파손을 예방함은 물론, 비구골의 손상을 최소화하며 비구컵만을 비구골로부터 정확하게 탈거할 수 있다.
