Abstract

A surgical system has an ultrasound treatment instrument having an ultrasound transducer, a power supply apparatus to which the ultrasound treatment instrument is detachably connected, an energy supply section that supplies drive energy to the ultrasound transducer, a clock that measures a present time, a time updating section that outputs the present time, a storage section that stores a final updated time that is updated finally in the present time, and a number of times of use, a time period calculation section that calculates a non-connection time period of the ultrasound treatment instrument to the power supply apparatus, and a processing section that performs processing of generating an update signal that causes the number of times of use to be updated in accordance with a determination result with respect to the non-connection time period and a result of determination with respect to a parameter.

First claim

What is claimed is:

1. A surgical system, comprising:
an ultrasound treatment instrument having an ultrasound transducer;
a power supply apparatus to which the ultrasound treatment instrument is detachably connected;
an energy supply section that is provided in the power supply apparatus, and supplies drive energy that causes the ultrasound transducer to be ultrasound-driven as output energy;
a clock that is provided in the power supply apparatus, and measures a present time;
a time updating section that is provided in the power supply apparatus, and outputs the present time;
a storage section that is provided in the ultrasound treatment instrument, stores a final updated time as an updated time that is at least finally updated in the present time which is outputted from the time updating section, and stores a number of times of use of the ultrasound treatment instrument;
a time period calculation section that calculates a non-connection time period in which the ultrasound treatment instrument and the power supply apparatus are not connected based on a difference between the final updated time which is stored in the storage section, and the present time by the clock;
a comparison section that determines whether or not the non-connection time period which is calculated in the time period calculation section exceeds a predetermined time period;
a processing section that performs processing of generating an update signal that causes the number of times of use to be updated in accordance with a result of determination with respect to a parameter including at least one of a number of output times of the drive energy, an output time period of the drive energy, an output power of the drive energy, an output current integrated value of the drive energy, an output voltage integrated value of the drive energy, an output power integrated value of the drive energy, a continuous output time period of the drive energy, an output time period integrated value of the drive energy, and a connection time period of the ultrasound treatment instrument and the power supply apparatus, when it is determined in the comparison section that the non-connection time period exceeds the predetermined time period; and
a number of times of use updating section that updates the number of times of use based on the update signal.

2. The surgical system according to claim 1 , wherein
the processing section performs processing of not generating the update signal which updates the number of times of use when it is determined that the non-connection time period does not exceed the predetermined time period.

3. The surgical system according to claim 1 , wherein
the storage section is provided in the ultrasound treatment instrument, stores the final updated time as the updated time which is at least finally updated in the present time which is regularly outputted from the time updating section, and stores the number of times of use of the ultrasound treatment instrument, and number of times update identification information as identification information on whether or not a flag state is a flag state in which the number of times of use in a case of the ultrasound treatment instrument being connected to the power supply apparatus at a previous time is updated,
the processing section performs first processing of whether or not to generate the update signal which updates the number of times of use in accordance with a case of an identification result of the number of times update identification information by further identifying the number of times update identification information, in a case of a determination result that the non-connection time period does not exceed the predetermined time period, and
performs second processing of generating the update signal in accordance with a determination result with respect to the parameter, after setting the flag state to a flag state in which the number of times update identification information is not updated, in a case of a determination result that the non-connection time period exceeds the predetermined time period.

4. The surgical system according to claim 3 , wherein
when the processing section performs the first processing, the processing section does not update the number of times of use in a case of an identification result of the flag state in which the number of times update identification information is updated, and
performs processing of generating the update signal which updates the number of times of use in accordance with the determination result with respect to the parameter in a case of an identification result that the flag state is not the flag state in which the number of times update identification information is updated.

5. The surgical system according to claim 3 , wherein
when the processing section performs the second processing, the processing section performs processing of generating the update signal which causes the number of times of use to be updated, and updating the number of times of use update identification information, in a case of a determination result of exceeding a parameter threshold value that is set to the parameter in advance, with respect to a calculation value of the parameter.

6. The surgical system according to claim 1 , further comprising:
a number of output times calculation section that calculates the number of output times at which the drive energy is outputted to the ultrasound transducer from the energy supply section, in a state in which the ultrasound treatment instrument is connected to the power supply apparatus,
wherein when the number of output times as the parameter exceeds a number of output times threshold value that is set in advance, the processing section generates the update signal that causes the number of times of use to be updated, and
the number of times of use updating section updates the number of times of use to increase the number of times of use by one.

7. The surgical system according to claim 1 , wherein
the parameter is an output parameter in a case in which the drive energy is outputted to the ultrasound transducer from the energy supply section, and
the processing section performs processing of generating the update signal which causes the number of times of use to be updated based on a determination result with respect to the output parameter which is outputted to the ultrasound transducer.

8. The surgical system according to claim 7 , further comprising:
an output time period calculation section that calculates the output time period in which the drive energy is actually outputted to the ultrasound transducer from the energy supply section, in a state in which the ultrasound treatment instrument is connected to the power supply apparatus,
wherein the processing section generates the update signal which causes the number of times of use to be updated when the output time period of the drive energy as the output parameter exceeds an output time period threshold value that is set in advance, and
the number of times of use updating section updates the number of times of use to increase the number of times of use by one.

9. The surgical system according to claim 8 , wherein
the output time period calculation section calculates the continuous output time period in which continuous output is performed as the output time period,
the processing section generates the update signal which causes the number of times of use to be updated when the continuous output time period in which the drive energy is continuously outputted to the ultrasound transducer from the energy supply section exceeds a continuous output time period threshold value that is set in advance, and
the number of times of use updating section updates the number of times o
