The heating element, and surgical apparatus employing

摘要

The present invention relates to a heating element, the dimensions of less than one centimeter, including: - a metal substrate (1) which is formed of a material having a conductivity or thermal conductivity greater than 5 w / m.k, and an ultimate tensile strength, measured at room temperature greater than 400 mpa and which comprises a working face adapted to be placed in contact with a medium or of an element to be heated, - a conductive layer (3) which is supported by a face of the substrate opposite to the working face and which forms a circuit comprising two components of the power supply connected by a resistive element and intended to be connected to a current source, and - a dielectric layer (2) is interposed between the conductive layer and the metal substrate.
