ABSTRACT:
A surgical knife especially suited for surgical procedures such as a tympanoplasty comprises a handle having a proximal and a distal end, with a curved blade rotatably carried on a post on the distal end of the handle. The blade extends radially outward from the post and beyond the end of the post in roughly an "S" shape. The cutting edge of the blade is on the end of the "S" and is thus spaced apart from and beyond the end of the post, where it can swivel about the axis of the post. When cutting, the blade will follow the direction the handle is moved, swiveling into alignment with that direction by the pressure of the tissue it is cutting.
