Abstract

A control device for an ablation treatment tool includes: a target-value storage unit that stores a target value for the total treatment area; an energy-source output unit that outputs, to the ablation treatment tool, an energy source for performing ablation treatment; an area calculation unit that calculates the total treatment area of the ileal mucosa on which the ablation treatment has been performed; and a control unit that controls termination of the ablation treatment performed by the ablation treatment tool. The control unit notifies an operator of the termination of the ablation treatment or stops the output of the energy source from the energy-source output unit when the calculated total treatment area of the ileal mucosa becomes equal to or greater than the target value.

First claim

The invention claimed is:

1. An ablation-treatment-tool control device for controlling an ablation treatment tool to perform ablation treatment on ileal mucosa, which covers an inner surface of an ileum, the ablation-treatment-tool control device comprising:
a target-value storage unit configured to store a target value for a total treatment area of the ileal mucosa, the target value being set on the basis of at least one of characteristics and conditions of a patient;
an energy-source output unit configured to output, to the ablation treatment tool, an energy source for performing the ablation treatment;
an area calculation unit configured to calculate the total treatment area, which is a total of areas of treatment regions of the ileal mucosa on which the ablation treatment has been performed for at least two or more treatment regions by the ablation treatment tool; and
a control unit configured to:
determine whether the calculated total treatment area is equal to or greater than the target value; and
in response to determining that the calculated total treatment area is equal to or greater than the target value, perform one or more of stop the output of the energy source from the energy-source output unit to terminate the ablation treatment and notify an operator of the termination of the ablation treatment.

2. The ablation-treatment-tool control device according to claim 1 , wherein:
a unit treatment area, which is a treatment area of the ileal mucosa per single ablation treatment performed by the ablation treatment tool, is fixed; and
the area calculation unit is configured to calculate the total treatment area by multiplying the unit treatment area by a number of times the energy source is output from the energy-source output unit.

3. The ablation-treatment-tool control device according to claim 1 , wherein the area calculation unit is configured to:
receive an endoscopic image of the ileal mucosa from an endoscope;
calculate an area of a new treatment region every time the ablation treatment is performed on the ileal mucosa, on the basis of the endoscopic image; and
calculate the total treatment area by adding up the calculated areas of the treatment regions.

4. An ablation system comprising:
an ablation treatment tool; and
the ablation-treatment-tool control device according to claim 1 , which is configured to control the ablation treatment tool.

5. The ablation system according to claim 4 , further comprising an endoscope that has a treatment-tool channel and is configured to be inserted into the ileum,
wherein the ablation treatment tool is configured to be inserted through the treatment-tool channel.

6. An ablation-treatment-tool control device for controlling an ablation treatment tool to perform ablation treatment on ileal mucosa, which covers an inner surface of an ileum, the ablation-treatment-tool control device comprising:
a target-value storage unit configured to store a target value for a total treatment area of the ileal mucosa, the target value being set on the basis of at least one of characteristics and conditions of a patient;
an energy-source output unit configured to output, to the ablation treatment tool, an energy source for performing the ablation treatment;
an area calculation unit configured to calculate the total treatment area, which is a total of areas of treatment regions of the ileal mucosa on which the ablation treatment has been performed for at least two or more treatment regions by the ablation treatment tool; and
a control unit configured to:
determine whether an area that is obtained by subtracting the target value from a sum of the calculated total treatment area and an area of a next single treatment region is equal to or greater than an area equal to a predetermined ratio of the area of the next single treatment region; and
in response to determining that the area that is obtained by subtracting the target value from the sum of the calculated total treatment area and the area of the next single treatment region is equal to or greater than the area equal to the predetermined ratio of the area of the next single treatment region, perform one or more of stop the output of the energy source from the energy-source output unit to terminate the ablation treatment and notify an operator of the termination of the ablation treatment.

7. The ablation-treatment-tool control device according to claim 6 , wherein:
a unit treatment area, which is a treatment area of the ileal mucosa per single ablation treatment performed by the ablation treatment tool, is fixed; and
the area calculation unit is configured to calculate the total treatment area by multiplying the unit treatment area by a number of times the energy source is output from the energy-source output unit.

8. The ablation-treatment-tool control device according to claim 6 , wherein the area calculation unit is configured to:
receive an endoscopic image of the ileal mucosa from an endoscope;
calculate an area of a new treatment region every time the ablation treatment is performed on the ileal mucosa, on the basis of the endoscopic image; and
calculate the total treatment area by adding up the calculated areas of the treatment regions.

9. An ablation system comprising:
an ablation treatment tool; and
the ablation-treatment-tool control device according to claim 2 , which is configured to control the ablation treatment tool.

10. The ablation system according to claim 9 , further comprising an endoscope that has a treatment-tool channel and is configured to be inserted into the ileum,
wherein the ablation treatment tool is configured to be inserted through the treatment-tool channel.
