摘要:
A powered surgical apparatus for use with a source of irrigation fluid and a source of suction and for powering a surgical tool such as a cutting blade. The surgical apparatus includes a handpiece and a cutting blade retention assembly integrated in passage in a distal end of the handpiece. The retention assembly includes an aligned, pair of radially movable buttons, aligned in axially extending passages in communication with the passage in the distal end of the handpiece, the movable buttons can engage with and cause rotational movement of a collet member assembly rotatably supported in the passage in the distal end of the handpiece. The collet assembly includes a plurality of rolling lock members which can be moved by the collet member from a first or lock position, in which the lock members are forced by the wall of the passage to extend inwardly of the collet member to engage a groove of the surgical tool, and a second or unlocked position, in which the lock members are aligned with a recess in the wall of the passage and are not forced to extend inwardly of the collet member.
