Abstract
Abstract An ultrasonic surgical cutting instrument includes a handpiece containing an ultrasonic generator. A hollow cutting probe is connected to the handpiece and is longitudinally moved at ultrasonic frequency when the generator is energized. The hollow probe has a cutting edge or edges formed thereon. One embodiment has a side cutting edge for side cutting action of skin, tissue, or bone. Other embodiments have a cutting edge formed on the tip of the probe. The hollow probe allows cut tissue or bone to be removed from the operative site by a vacuum applied thereto. The hollow probe also allows an irrigating fluid to be introduced to the operative site.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
An ultrasonic surgical cutting instrument comprising: a handpiece having a piezoelectric transducer therein for generating ultrasonic vibratory motion; and a hollow tube having an open end connected to said handpiece and transducer and a closed distal end, said tube having an opening formed in the side of said tube adjacent to said distal end, said opening having a sharpened cutting edge formed about the periphery of said opening with that portion of the cutting edge adjacent to the distal end facing away from the distal end substantially parallel to the longitudinal axis of said tube.
Claim 2
Dependent Claim
95 words
An ultrasonic surgical cutting instrument comprising: a handpiece having a piezoelectric transducer therein for generating ultrasonic vibratory motion; and a hollow tube having an open end connected to said handpiece and transducer and a closed distal end, said tube having an opening formed in the side of said tube adjacent to said distal end, said opening having a sharpened cutting edge formed about the periphery of said opening with that portion of the cutting edge adjacent to the distal end facing away from the distal end substantially parallel to the longitudinal axis of said tube.
Claim 3
Dependent Claim
17 words
An ultrasonic surgical cutting instrument as set forth in claim 1, wherein said distal end is blunt.
Claim 4
Dependent Claim
17 words
An ultrasonic surgical cutting instrument as set forth in claim 1, wherein said distal end is rounded.
Claim 5
Dependent Claim
33 words
An ultrasonic surgical cutting instrument as set forth in claim 1, wherein said opening is formed at an angle through the side of said probe and through a portion of the distal end.
Claim 6
Dependent Claim
22 words
An ultrasonic surgical cutting instrument as set forth in claim 4, wherein at least a portion of the cutting edge is serrated.
Claim 7
Dependent Claim
93 words
A cutting probe for use with an ultrasonic handpiece comprising: a hollow tube having an open end and a closed blunt distal end, said open end adapted to attach to said handpiece; and said tube having an opening formed in the side of the hollow tube adjacent to the distal end, said tube having a sharpened cutting edge formed about the periphery of the opening with that portion of the cutting edge adjacent to the distal end facing away from the distal end substantially parallel to the longitudinal axis of said hollow tube.
Claim 8
Dependent Claim
93 words
A cutting probe for use with an ultrasonic handpiece comprising: a hollow tube having an open end and a closed blunt distal end, said open end adapted to attach to said handpiece; and said tube having an opening formed in the side of the hollow tube adjacent to the distal end, said tube having a sharpened cutting edge formed about the periphery of the opening with that portion of the cutting edge adjacent to the distal end facing away from the distal end substantially parallel to the longitudinal axis of said hollow tube.
Claim 9
Dependent Claim
98 words
A cutting probe for use with an ultrasonic handpiece comprising: a hollow tube having an open end and a blunt distal end, said open end adapted to attach to said handpiece; and said tube having an opening formed at an angle through the side of said hollow tube and through a portion of the distal end, said tube having a sharpened cutting edge formed about the periphery of the opening with that portion of the cutting edge adjacent to the distal end facing away from the distal end substantially parallel to the longitudinal axis of said hollow tube.
Claim 10
Dependent Claim
98 words
A cutting probe for use with an ultrasonic handpiece comprising: a hollow tube having an open end and a blunt distal end, said open end adapted to attach to said handpiece; and said tube having an opening formed at an angle through the side of said hollow tube and through a portion of the distal end, said tube having a sharpened cutting edge formed about the periphery of the opening with that portion of the cutting edge adjacent to the distal end facing away from the distal end substantially parallel to the longitudinal axis of said hollow tube.
Claim 11
Dependent Claim
15 words
A cutting probe as set forth in claim 6, wherein said closed end is rounded.
