From flintstone to diamond blade: a new multifunctional instrument for use in coronary surgery

We report on the development and clinical application of a diamond surgical
knife specially designed for the preparation, initial incision, and
bidirectional enlargement of coronary arteries. The ergonomic design of the
knife enables the performance of all the necessary steps in a coronary
incision with a single instrument and obviates the need for different
shaped knives and scissors during preparation. The lasting sharpness of the
diamond blade results in a far cleaner, less traumatic, cutting edge as can
be demonstrated by scanning electron micrographs of incised coronary walls
after the use of various types of coronary knives and scissors.
