Surgical Cutting Accessory With Malleable Tube Assembly

A cutting accessory configured to be removably coupled to a handpiece of a surgical cutting instrument including a motor, the cutting accessory comprising:

• an outer hub configured to be coupled with the handpiece;
• a drive hub rotatably disposed within the outer hub and configured to be operably coupled to the motor;
• and
• a tube assembly comprising an outer tube coupled to and extending distally from the outer hub, an inner tube coupled to the drive hub and coaxially disposed within the outer tube, and a cutting tip disposed on the inner tube, wherein the inner tube comprises at least one flexible region,
• wherein the outer tube is formed with a proximal malleable region and a distal malleable region that is spaced apart from the proximal malleable region to define a rigid proximal segment, a rigid intermediate segment, and a rigid distal segment of the tube assembly, and wherein the proximal and distal malleable regions are configured to be independently bent and/or rebent by a user to a shaped configuration, and maintain the tube assembly in the shaped configuration.

• wherein the outer tube is formed with a proximal slotted region and a distal slotted region in which a series of slots respectively form a proximal malleable spine and a distal malleable spine configured to be independently bent and/or rebent by a user to a shaped configuration, and maintain the tube assembly in the shaped configuration, and wherein spacing between adjacent slots of a series of slots of the proximal slotted region is greater than spacing between adjacent slots of a series of slots of the distal slotted region.
