US 6,740,085 B2 · Heating treatment system

Abstract

A heating treatment system consists mainly of coagulating/incising forceps in which a plurality of heating elements are incorporated, and a main unit that feeds power to the heating elements incorporated in the coagulating/incising forceps and that drives and controls the heating elements. The main unit can be connected to coagulating/incising forceps in which up to four heating elements are incorporated. The main unit includes element temperature measurement/output control units and temperature setting units which are associated with four channels allocated to the heating elements. A control unit controls the element temperature measurement/output control units and temperature setting units. The control unit judges the type of connected forceps by referencing data stored in advance in a memory using information of the type of forceps received from the coagulating/incising forceps, and controls power feed to the heating elements.

Dependent claims

A heating treatment system or treating a living tissue comprising:

a therapeutic instrument having a plurality of heating elements, which generate heat based on fed driving power, the therapeutic instrument further having a heat transfer plate that includes a first surface for contact with the living tissue, and a second surface, other than the first surface and coupled to said heating elements, said second surface not coming into contact with the living tissue;
a temperature level switch used to input an instruction for adjusting the temperature of said heat transfer plate;
a temperature-of-heating element setting circuit for setting temperature values, to which said plurality of heating elements should be heated, according to the instruction given using said temperature level switch;
and
a plurality of output circuits for feeding driving power to said heating elements according to the plurality of temperature values to which said heating elements should be heated and which are set by said temperature-of-heating element setting circuit.
