Electrosurgical instrument

The medical devices for electrosurgeries and the method (Fig. 8A) for forming heat welding in the 嵌合 (ed) organization are indicated. In one mode, at least one Joe of an instrument specifies the organization 嵌合 side holding conductive-resistance matrix of the non-conductive elastomer added by conductivity. Thus, 嵌合 surface portions are those each selected temperature covering the target-ized processing range that rose, and can be explained as a material of the positive temperature coefficient which has the original selected conductivity which decreased. Conductive - resistance matrix is about 60 °C * 80 °C, for example -- then, it fits in the heat treatment range made into the target for organization welding to be realized (bracket) -- it can be operated like. In one operation style, from Rf energy application, a 嵌合 side crosses mum scale portion on the surface of 嵌合, in the 嵌合 (ed) organization, modulates automatically and localizes ohmic heating spatially (155A). In another operation style, in order to cross and carry out the sweep of the organization, conductive - resistance matrix can guide the "wave" of Rf energy density, and, thereby, can carry out 融 arrival of the organization.
