Powered surgical apparatus, method of manufacturing powered surgical apparatus, and method of using powered surgical apparatus

A method of manufacturing a handle that is usable as a motorized surgical apparatus with a movable cutting blade assembly, the cutting blade assembly including an inner tube rotatable by a motor and defining a cutting surface, and an outer tube defining a cutting window, the method comprising:

• forming an upper portion having a distal section that is connectable to the movable cutting blade assembly, the distal section of the upper portion including a manually rotatable member, the member being connectable to the outer tube such that manual rotation of the member results in rotation of the outer tube and thereby reorientation of the cutting window;
• and
• connecting a lower portion to the upper portion such that the lower portion extends downwardly from the upper portion so as to define an angle of less than 90° with the distal section of the upper portion;
• the member being freely rotatable relative to a remainder of the upper portion without becoming disconnected from the remainder of the upper portion, the member being rotatable during operation of the powered surgical apparatus while the inner tube rotates, the member being rotatable by virtue of a rotational force applied by a tip of at least one of a user's fingers.
