Abstract

A treatment system comprises a first power supply apparatus and a second power supply apparatus each connectable with a surgical device and a neutral electrode, the first power supply apparatus being electrically connected with the second power supply apparatus, the treatment system treating a living tissue while performing transmission and reception of information between the first and second power supply apparatuses, wherein, in a case where the neutral electrode is connected to only one of the first and second power supply apparatuses, an output of the surgical device connected to the second power supply apparatus is inhibited during an output of the surgical device connected to the first power supply apparatus, and the output of the surgical device connected to the first power supply apparatus is inhibited during the output of the surgical device connected to the second power supply apparatus.

First claim

What is claimed is:

1. A treatment system for use with a living tissue, the treatment system comprising:
a first power supply apparatus configured to be connectable with a first electric surgical device and a first neutral electrode, the first power supply apparatus including:
a first high-frequency power supply configured to supply high-frequency current to the first electric surgical device bused on a first operation instruction signal,
a first detector configured to detect whether the first neutral electrode is connected,
a first processor programmed to control the first power supply apparatus,
a first switch configured to switch a path of the high-frequency current collected by the first neutral electrode, and
a third switch configured to switch a first path connecting the first high-frequency power supply section and the first electric surgical-device into a conducting state or a non-conducting state; and

a second power supply apparatus configured to be connectable with a second electric surgical device and a second neutral electrode, in which the first power supply apparatus and the second power supply apparatus are electrically connected with each other through a connector section and the living tissue is treated while transmission and reception of information is performed between the first power supply apparatus and the second power supply apparatus, the second power supply apparatus including:
a second high-frequency power supply configured to supply high-frequency current to the second electric surgical device based on a second operation instruction signal,
a second detector configured to detect whether the second neutral electrode is connected,
a second processor programmed to control the second power supply apparatus,
a second switch configured to switch a path of the high-frequency current collected by the second neutral electrode, and
a fourth switch configured to switch a second path connecting the second high-frequency power supply section and the second electric surgical device into a conducting state or a non-conducting state; wherein:

in a case where the first processor and the second processor determine that the first detector detects the first neutral electrode and that the second detector does not detect the second neutral electrode, the first processor and the second processor are configured to:
control the first switch and the second switch such that the high-frequency current collected by the first neutral electrode flows to the first high-frequency power supply when the first operation instruction signal is inputted to the first high-frequency power supply, and
control the first switch and the second switch such that the high-frequency current collected by the first neutral electrode flows to the second high-frequency power supply section through the connector section when the second operation instruction signal is inputted to the second high-frequency power supply, and

in a case where the first processor and the second processor determine that the second detector detects the second neutral electrode and that the first detector does not detect the first neutral electrode, the first processor and the second processor are configured to:
control the first switch section and the second switch section such that the high-frequency current collected by the second neutral electrode flows to the first high-frequency power supply through the connector section when the first operation instruction signal is inputted to the first high-frequency power supply,
control the first switch and the second switch such that the big-frequency current collected by the second neutral electrode flows to the second high-frequency power supply when the second operation instruction signal is inputted to the second high-frequency power supply,
control the third switch and the fourth switch such that the first path is in the conducting state and the second path is in the non-conducting state when the first operating instruction signal is inputted to the first high-frequency power supply, and
control the third switch and the fourth switch such that the first path is in the non-conducting state and the second path is in the conducting state when the second operation instruction signal is inputted to the second high-frequency power supply.

2. The treatment system according to claim 1 , wherein
when one of the first detector and the second detector detects connection, the first processor or the second processor are configured to perform control to disable a function of the other detector.

3. The treatment system according to claim 1 , wherein
when, after one of the first detector and the second detector detects connection, another of the first detector and the second detector detects connection, the first processor and the second processor are configured to perform control to notify an error.

4. The treatment system according to claim 1 , wherein
information concerning magnitude of energy capable of being supplied from the first high-frequency power supply and the second high-frequency power supply is transmitted and received between the first power supply apparatus and the second power supply apparatus, and
the first processor and the second processor are configured to perform control to disable a function of the second detector, when the first processor and the second processor determine that the magnitude of energy capable of being supplied from the first high-frequency power supply is larger than the magnitude of energy capable of being supplied from the second high-frequency power supply, and perform control to disable a function of the first detector, when the first processor and the second processor determine that the magnitude of energy capable of being supplied from the second high-frequency power supply is larger than the magnitude of energy capable of being supplied from the first high-frequency power supply.

5. A treatment system for use with a living tissue, the treatment system comprising:
a first power supply apparatus configured to be connectable with a first electric surgical device and a first neutral electrode, the first power supply apparatus including:
a first high-frequency power supply configured to supply high-frequency current to the first electric surgical device based on a first operation instruction signal,

a second power supply apparatus configured to be connectable with a second electric surgical device and a second neutral electrode, in which the first power supply apparatus and the second power supply apparatus are electrically connected with each other through a connector section and the living tissue is treated while transmission and reception of information is performed between the first power supply apparatus and the second power supply apparatus, the second power supply apparatus including:
a second high-frequency power supply configured to supply high-frequency current to the second electric surgical device based on a second operation instruction signal,
a second detector configured to detect whether the second neutral electrode is connected,
a second processor programmed to control the second power supply apparatus; wherein:

in a case where the first processor and the second processor determine that the first detector detects the first neutral electrode and that the second detector does not detect the second neutral electrode, the first processor and the second processor are configured to perform control to:
disable supply of the high-frequency current from the second high-frequency power supply to the second electric surgical device when the first operation instruction signal is inputte
