Abstract

A powered surgical apparatus can be used with a source of irrigation fluid and a source of suction. The powered surgical apparatus can include a cutting blade assembly and a handle. The handle can include an upper portion defining a distal section connectable to the cutting blade assembly and a lower portion extending downwardly from the upper portion. The handle can be connectable to the source of irrigation fluid and the source of suction. The system can also include a manually actuable input device that provides at least one signal relevant to at least one operation of the system, and a controller that receives the at least one input signal and provides an output signal to perform the at least one operation of the system.

Claims

1. A collet assembly usable with a powered surgical apparatus that includes a handle and a movable cutting blade assembly that includes an outer hub secured to an outer tube that defines a cutting window, the collet assembly comprising:

a base mount secured to the handle;

a stationary cam secured to the base mount, the stationary cam defining teeth along a distal face of the stationary cam;

a sliding cam that defines teeth along a proximal face of the sliding cam and at least one groove, the teeth of the sliding cam being directly engageable with the teeth of the stationary cam to prevent relative rotation between the stationary cam and the sliding cam;

at least one ball disposed in the at least one groove of the sliding cam;

a swivel shell attached to the sliding cam via the at least one ball such that rotation of the swivel shell moves the teeth of the sliding cam out of engagement with the teeth of the stationary cam; and

a retention sleeve that receives a proximal end of the outer hub of the cutting blade assembly, the retention sleeve being secured to the sliding cam and rotatable relative to the stationary cam;

wherein rotation of the swivel shell causes a corresponding rotation of the retention sleeve and a reorientation of the cutting window of the outer tube of the cutting blade assembly.

2. The collet assembly according to claim 1, wherein the at least one groove of the sliding cam includes two grooves.

3. The collet assembly according to claim 1, wherein the at least one groove of the sliding cam is V-shaped such that the groove extends along an annular surface of the sliding cam and is directed along a longitudinal direction of the sliding cam.

4. The collet assembly according to claim 1, wherein the retention sleeve includes a flange that is trapped in a gap defined between the stationary cam and the base mount, the retention sleeve being rotatable relative to the stationary cam and the base mount.

5. The collet assembly according to claim 1, wherein the retention sleeve defines at least one key that communicates with at least one interior groove of the sliding cam so as to secure the sliding cam to the retention sleeve.

6. The collet assembly according to claim 1, further including a spring that applies a pressing force to the sliding cam such that the teeth of the sliding cam are engaged with the teeth of the stationary cam preventing relative rotation therebetween unless the swivel shell is rotated to overcome the pressing force and thereby disengage the teeth of the sliding cam from the teeth of the stationary cam.
