    Abstract: A surgical device comprising: a handle assembly; a locking collar; and a set of replaceable bits that load along an axis into the handle assembly; wherein the locking collar is fully removable from the handle assembly, the locking collar loads axially to a first position, and the locking collar rotates between the first position and a second position; wherein, in the first position, the locking collar is free to be axially removed from the handle assembly and the replaceable bits are free to be loaded or unloaded from the handle assembly; wherein, in the second position, the locking collar is prevented from axial movement relative to the handle assembly and the replaceable bits are prevented from being received within, or removed from, the handle assembly; and the locking collar is guided to the first position and between the first position and the second position by a groove in the handle assembly mating with a member carried by the locking collar. And a surgical device comprising: a handle assembly comprising a rotatable drive shaft; a removable handle assembly adapter for connection to the handle assembly, the removable handle assembly adapter comprising a rotatable transmission shaft for connection to the rotatable drive shaft of the handle assembly; and a removable nosepiece assembly for connection to the removable handle assembly adapter and for selectively securing the shaft of a working element to the rotatable transmission shaft of the removable handle assembly adapter; wherein the removable handle assembly adapter and the removable nosepiece assembly each comprise a locking collar; and wherein the removable handle assembly adapter and the handle assembly each comprise a connector assembly, the connector assembly comprising: a housing comprising an opening; a collet sleeve disposed within the opening and connected to an input shaft, the collet sleeve comprising a lumen for receiving an output shaft; a locking element movable relative to the collet sleeve between (i) a locked position in which the output shaft is secured to the collet sleeve, and (ii) an unlocked position in which the output shaft is not secured to the collet sleeve; and a cam element movable relative to the collet sleeve between (i) a first position in which the locking element is free to assume its unlocked position, and (ii) a second position in which the cam element cams the locking element into the locked position; such that movement of the locking collar causes the cam element to move between the first position and the second position.

    Abstract: A surgical apparatus which includes a handpiece having a passage. The retention assembly includes a pair of radially movable buttons, aligned in axially extending passages in communication with the passage and can engage with and cause rotational movement of a collet member assembly rotatably supported in the passage. The collet assembly includes rolling lock members which can be moved by the collet member from a lock position, in which the lock members are forced by the wall of the passage to extend inwardly of the collet member and an 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. The surgical apparatus may find particular use with irrigation fluid, suction, and powering of a surgical tool. The passage may include a cutting blade retention assembly integrated in the passage.
