Claim Text:
1. A power operated rotary knife comprising: a handle assembly including an elongated cylindrical handle housing defining a handle assembly longitudinal axis extending through a throughbore in the handle housing; a head assembly coupled to and extending from a distal end of the handle assembly, the head assembly including a rotary knife blade supported by a blade housing for rotation about a central axis of rotation, the rotary knife blade including an annular body having an inner wall and a radially spaced apart outer wall, the inner wall defining a central open region extending from a first end to a spaced apart second end of the annular body and a drive section adjacent a first end of the annular body, the drive section defining a driven gear including a set of gear teeth formed in the outer wall of the annular body, and a blade section adjacent a second end of the annular body, the head assembly further including a frame securing the blade housing to the distal end of the handle assembly in a position radially offset from the handle housing such that the central axis of rotation of the rotary knife blade is spaced apart from and is substantially parallel to the handle assembly longitudinal axis; and a vacuum attachment assembly including a vacuum adapter and a vacuum hose, the vacuum adapter including an adapter body having an inner wall defining a central open region extending from a first end to a spaced apart second end of the adapter body, the first end of the vacuum adapter secured to the vacuum hose and the second end of the vacuum adapter including a housing clamp secured to the blade housing, the adapter body defining an adapter central axis extending through the central open region and the central open region being in fluid communication with the central open region of the annular body of the rotary knife blade, the adapter body extending at an angle away from the handle housing such that the adapter central axis is transverse with respect to the central axis of rotation of the rotary knife blade and the handle assembly longitudinal axis.
