Powered surgical apparatus, method of manufacturing powered surgical apparatus, and method of using powered surgical apparatus
First Claim
1. A handle assembly usable as a powered surgical apparatus with a source of suction and a source of irrigation fluid, comprising:
- a movable cutting blade assembly that includes a rotatable inner tube defining a cutting surface and an outer tube defining a cutting window, the inner tube extending within the outer tube so as to define a tube gap therebetween;
a handle having an upper portion and a lower portion, the upper portion defining a distal section that is connectable to the movable cutting blade assembly, the upper portion defining a integral proximal end having a suction coupling and an irrigation fluid coupling, the suction coupling and the irrigation fluid coupling each forming a proximally extending convex projection, the handle defining an irrigation fluid channel that extends from the irrigation fluid coupling to the cutting blade assembly, and a suction channel extending from the suction coupling to the cutting blade assembly, the irrigation fluid channel being in fluid communication with the tube gap; and
a connector connected to the proximal end of the handle at the irrigation fluid coupling and the suction coupling, the connector defining an irrigation fluid entry channel that is contiguous with the irrigation fluid channel of the handle, and a suction entry channel that is contiguous with the suction channel of the handle.

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.

15. A method of manufacturing a handle assembly that is usable as a powered surgical apparatus, comprising:
-
forming a handle having an upper portion and a lower portion, the upper portion defining a distal section that is connectable to a movable cutting blade assembly, the movable cutting blade assembly including a rotatable inner tube defining a cutting surface and an outer tube defining a cutting window, the inner tube extending within the outer tube so as to define a tube gap therebetween; forming an irrigation fluid coupling and a suction coupling at a proximal end of the upper portion, the irrigation fluid coupling, the suction coupling, and the proximal end of the upper portion being integral with the upper portion, the irrigation fluid coupling and the suction coupling each forming a proximally extending convex projection; forming an irrigation fluid channel in the handle from the irrigation fluid coupling to the cutting blade assembly, the irrigation fluid channel being in fluid communication with the tube gap; forming a suction channel in the handle from the suction coupling to the cutting blade assembly; connecting a connector to the proximal end of the handle at the irrigation fluid coupling and suction coupling; forming an irrigation fluid entry channel in the connector that is contiguous with the irrigation fluid channel of the handle; and forming a suction entry channel in the connector that is contiguous with the suction channel of the handle.
