Treating apparatus and treating device for treating living-body tissue

Abstract

In a treating apparatus, a forceps body as a treating device is connected to a generator as a control device. The forceps body mainly includes a pair of handle portions, which are used for manipulation by being held by an operator, a pair of jaws provided between the handle portion and the pair of jaws, which are used to coagulate/resect by grasping living-body tissue to be treated and a pair of scissors component members. A heating member, which is a heat generating source as a heat generating portion for applying heat energy to living-body tissue, is embedded at least one of the jaws. A pair of electrode portions, which is a treating energy generator, is provided to the pair of jaws. By supplying bipolar electric surgical knife current between the pair of electrode portions, high frequency current as treating energy is applied to the grasped living-body tissue.
