Abstract
An ultrasonic osteotome in accordance with the present invention comprises a shaft having a distal end portion with a lateral outer surface and further comprises a cutting blade connected to the distal end portion of the shaft at least in part at the lateral outer surface. The lateral outer surface extends so far on opposite sides of the blade as to block or stop penetration of the shaft into an incision formed in bone tissue by the blade. The blade can include a cutting notch or have a variable cutting depth depending on the angle of the distal end of the instrument to the surface of a target tissue mass.
Claims14
An ultrasonic osteotome comprising:
- a shaft having a distal end portion with a lateral outer surface;
- and
- a planar or flat cutting blade connected to said distal end portion of said shaft at least in part at said lateral outer surface, at least a portion of said blade extending a longitudinally along said distal end portion of said shaft and being disposed laterally on one side thereof so that a portion of said shaft is distal to at least part of said blade,
- said lateral outer surface extending so far on opposite sides of said blade as to block or stop penetration of said shaft into an incision formed in bone tissue by said blade wherein said blade has an edge formed on at least one side with a notch adjacent to said lateral outer surface and a protruding bulge on a side of said notch opposite said lateral outer surface, said shaft extending in a distal direction beyond said notch, thereby serving to define said notch along one side thereof.
