Abstract
Treatment equipment for treating body tissue comprises heater elements which are heated by electric power supplied from an electric power supply circuit, and the heat of the heater elements is provided to the body tissue through a heat transmitting member. The state of thermal connection between the heater elements and the heat transmitting member is determined by a determining device for determining the thermal connection state.
Claims29
A heat-emitting treatment device comprising:
- heater elements for emitting heat to treat body tissue;
- an electric power supplying circuit for supplying electric power so that the heater elements emit heat;
- a heat-transmitting member connected with the heater elements so as to provide the heat from the heater elements, heated by supplying electric power thereto, to the body tissue;
- and
- a determining device for determining the heat connection state of the heater elements and the heat-transmitting member;
- wherein the determining device is configured for detecting an amount of change in a temperature during a predetermined period of time of the heater elements, determining the heat connection state of the heater elements and the heat transmitting member, and comparing the detected amount of change in a temperature and a preset threshold value.
A control method for a heat-emitting treatment device comprising heater elements for emitting heat to treat body tissue and a heat-transmitting member for transmitting heat from the heater elements to body tissue, the method comprising:
- an electric power supplying step for supplying electric power so that the heater elements emit heat;
- a determining step for detecting an amount of change in a temperature during a predetermined period of time of the heater elements and determining the connection state of the heater elements and the heat-transmitting member by comparing the detected amount of change in a temperature and a preset threshold value;
- and
- an electric power changing step for changing the electric power supplied, based on the determination results of the determining step.
A control method for a heat-emitting treatment device comprising heater elements for emitting heat to treat body tissue and a heat-transmitting member for transmitting heat from the heater elements to body tissue, the method comprising:
