| Abstract: |
High incision velocity vibrating scalpel structure and method comprising motor means including a motor having a drive shaft rotatable on energizing the motor, an eccentric fly wheel secured to the drive shaft for rotation therewith and scalpel blade support structure rigidly secured to the motor, all resiliently mounted in a elongated hollow body member, to which motor means a scalpel blade may be secured and vibrated on energizing of the motor means to rotate the fly wheel and alternating or direct current means for selectively energizing the motor. A resilient pivot may also be provided for the motor means and a resilient boot is provided over one end of the body member between the body member and motor means for sealing the one end of the body member. In use, on energizing the motor means, the motor means, scalpel blade support structure and scalpel blade are caused to vibrate at a high velocity to incise tissue with the scalpel blade. Movement of the scalpel blade is primarily arcuately about the pivot mounting for the motor means, and this is primarily perpendicularly to the axis of rotation of the drive shaft, to a lesser extent longitudinally of the high incision velocity scalpel structure.

I claim:
1. High incision velocity vibrating scalpel structure comprising a body member, motor means positioned within the body member, means connected to the motor means for energizing the motor means, said motor means including an eccentric fly wheel member mounted in the motor means for rotation on energizing of the motor means, means resiliently mounting the motor means in the body member for permitting vibration of the motor means on rotation of the eccentric fly wheel member, wherein the motor means includes a motor having an axis of rotation and a drive shaft bent at an angle of approximately 1 degree to the axis of rotation of the motor, rotatable on energizing the motor and the eccentric fly wheel member is mounted on the drive shaft, and a scalpel blade secured to the motor means for vibration with the motor means on energizing of the motor means and rotation of the eccentric fly wheel member.
