Living tissue bonding system, treatment instrument control apparatus, and operation method of living tissue bonding system

A treatment instrument control apparatus configured to control treatment energy for living tissue to a clamping section configured to clamp the living tissue, the treatment instrument control apparatus comprising:

• a power source configured to generate the treatment energy for bonding the living tissue clamped by the clamping section;
• an output section provided on the clamping section and configured to output the treatment energy to the living tissue;
• a temperature measuring section configured to measure a temperature of the output section;
• a first calculating section configured to use a table or an equation stored beforehand and indicating a correlation between a temperature difference between the temperature of the output section measured in the temperature measuring section and a temperature of the living tissue clamped by the clamping section and an output value outputted from the power source to the clamping section, and to estimate the temperature difference from the table or the equation based on the output value from the power source according to an application time period of the treatment energy;
• a second calculating section configured to estimate the temperature of the living tissue from the temperature of the output section measured by the temperature measuring section and the temperature difference estimated by the first calculating section;
• and
• a control section configured to control the power source which generates power for the treatment energy, based on the temperature of the living tissue estimated by the second calculating section.

An operation method of a living tissue bonding system comprising:

• a step in which an output section provided on a clamping section outputs treatment energy by a power source generating the treatment energy for bonding living tissue clamped by the clamping section;
• a step in which a temperature measuring section measures a temperature of the output section;
• a step in which, using a table or an equation stored beforehand and indicating a correlation between a temperature difference between the temperature of the output section measured in the temperature measuring section and a temperature of the living tissue clamped by the clamping section and an output value outputted from the power source to the clamping section, a first calculation section estimates the temperature difference obtained from the table or the equation based on the output value from the power source according to an application time period of the treatment energy;
• a step in which a second calculating section estimates the temperature of the living tissue from the temperature of the output section measured by the temperature measuring section and the temperature difference estimated by the first calculating section;
• and
• a step in which a control section controls the power source based on the temperature of the living tissue estimated by the second calculating section.
