| 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 an 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 thus 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. Scalpel structure comprising a body member, motor means within the body members, said motor means having a longitudinal axis and including a motor, a scalpel blade support structure rigidly secured to the motor, a substantially flat scalpel blade rigidly secured to the scalpel blade support structure, said blade support structure extending exteriorly of the body member and having a longitudinal axis parallel to a longitudinal axis of the body member, means for vibrating the motor means on energizing the motor, said means for vibrating being connected to the motor means, pivot means including a fixed pivot axis extending perpendicularly of the longitudinal axis of the motor means, said pivot means pivotally supporting the motor means from the body member for reciprocating pivotal movement of the motor means and scalpel blade in the plane of the scalpel blade and in a plane perpendicular to the axis of the pivot means on energizing the motor, and means connected to the motor for energizing the motor.
