Next, the surgeon or the like turns on a switch (not shown) provided in the pneumoperitoneum device 23 to start supply of pneumoperitone gas from the pneumoperitoneum device 23 to the trocar 1.

The insufflation gas supplied from the insufflation apparatus 23 is injected into the body cavity 1002 of the subject through the composite cable 24, the composite connector 26, and the conduit 6.

Thereafter, when the surgeon visually confirms that the gas for insufflation is infused until the operation field in the body cavity 1002 is sufficiently secured, a switch (not shown) provided in the insufflation apparatus 23 is checked. By turning off, supply of the gas for insufflation from the insufflation apparatus 23 to the trocar 1 is stopped.

Subsequently, the surgeon or the like inserts the bipolar electric scalpel 11 into the body cavity 1002 inflated by injecting the gas for insufflation through the trocar 1 installed on the body wall 1001.

Then, for example, when the operator confirms that the treatment electrode 12 has reached the vicinity of the treatment target site in the body cavity 1002 by observing or visually observing an endoscopic image, the operator operates the power supply start switch 22A. Thus, power supply from the power supply device 21 to the trocar 1 is turned on.

With such supply of AC power, a magnetic field resonance phenomenon occurs between the power transmission coil unit of the trocar 1 and the power reception coil unit of the bipolar electric knife 11, and power transmission from the power transmission coil 4 to the power reception coil 17 occurs. The AC power received by the power receiving coil 17 is used as the driving power for the treatment electrode 12.

According to the medical wireless power feeding system 201 of the present embodiment as described above, the trocar 1 is supplied from the power transmission cable 25 A that transmits AC power supplied from the power supply device 21 to the trocar 1 and the pneumoperitoneum device 23.

The power transmission cable 25A and the air supply tube for connecting the conduit 6 and the air supply device are provided together (substantially integrally) in the composite cable 24, and the composite connector 26 is connected to the connector connection portion 3. What is necessary is just to comprise so that electrical connection of 3 A of electric terminals and the power transmission cable 25A, and connection of the opening part 6A and the said air supply tube may be performed at once (simultaneously).

In addition, for example, in the case where the function related to the water supply into the body cavity for the purpose of securing the visual field is realized by the cooperation of the conduit portion 6 of the trocar 1 and the water supply device (installed outside the body of the subject), The power transmission cable 25 A and the water supply tube for connecting the conduit 6 and the water supply device are provided together (substantially integrally) in the composite cable 24, and the composite connector 26 is attached to the connector connection portion 3. At this time, the electrical connection between the electrical terminal 3A and the power transmission cable 25A and the connection between the opening 6A and the water supply tube may be performed at the same time (simultaneously).

On the other hand, according to the present embodiment, for example, a receiving unit including an antenna or the like capable of receiving an image signal transmitted as a radio signal from an endoscope may be provided in the trocar 1 as a functional unit. When the function related to the input of the image signal imaged by the endoscope is realized by the cooperation of the receiving unit of the trocar 1 and the image input device (installed outside the body of the subject), the power transmission cable 25A And the image signal cable for connecting the receiving unit and the image input device are provided together (substantially integrally) in the composite cable 24, and when the composite connector 26 is attached to the connector connection unit 3, What is necessary is just to comprise so that the electrical connection of 3 A of electric terminals and the power transmission cable 25A, and the electrical connection of the said receiving part and the said image signal cable may be performed at once (simultaneously).

It is configured as follows. Further, according to the medical wireless power feeding system 202 of the present embodiment, for example, when the power received by the power receiving coil unit of the bipolar electric knife 41 is less than the power required for the operation of the LED 42, the LED 42 is extinguished.
