Figure 1-26 Electro surgical apparatus.
(1) Advantages of the use of electro surgery over mechanical (hand)
surgery are numerous. A discussion of these follows.
(a) The electrosurgery active electrode (operative tip) can perform two
processes simultaneously; it can seal as it cuts. The alternating current makes an
incision in an exceedingly fine line. By adjustment of the controls, this unit can also
cauterize, or literally cook, the tissue, thus closing (sealing) blood vessels instead of
tying each one individually with a suture. These two processes, cutting and sealing,
