Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a radiofrequency ablation device, and particularly to a radiofrequency ablation device used in surgical treatment.

[Prior art] High-frequency ablation devices conventionally used in endoscopic devices include
A plurality of output connectors are provided for connecting treatment tools such as a female holder, a female holder with a hand switch, and bipolar tweezers. A predetermined high-frequency output is guided to these treatment tools by operating a foot switch or a hand switch provided on a scalpel holder with a hand switch. In this case, the operator operates a selection switch or the like to select an output in order to guide a predetermined high-frequency output to a desired treatment instrument.

[Problems to be Solved by the Invention] In the conventional high-frequency ablation device as described above, when a foot switch or a hand switch is operated, high-frequency outputs corresponding to various surgical treatments are simultaneously generated. For this reason, if a treatment instrument is connected to all output connectors of the high-frequency ablation device, there is a possibility that an unintended output will be output from the treatment instrument, which may pose a danger in treatment. Also,
If a switch for selecting the type of output is provided, the operation for selecting the output is troublesome, and there is a risk of erroneous operation.

An object of the present invention is to provide a high-frequency ablation device that can safely and easily select a high-frequency output.

[Means for Solving the Problems 1] According to the present invention, at least one of the plurality of output connectors is connected to the output connector by the treatment implement connection detection member for detecting the connection of the treatment implement and the detection unit H. One of the parts is provided with a part for guiding a predetermined high frequency output.

[Function] According to the high-frequency ablation device of the present invention, when a plurality of treatment tools are connected to the output connector, only the high-frequency output system for one treatment tool is automatically selected, and only one type of output is guided to the treatment tool. It will be destroyed. This allows treatment to be performed safely without producing unintended types of output.

[Example] According to FIG. 7A1, the high-frequency ablation device 11 is provided with an output section 12 that outputs the high-frequency electricity 2A'3 and an output switching section 13 connected to the output terminal of the output section 12.

The output terminal section of the output switching section 13 is connected to the output connector section 14 . The output connector section 14 includes a plurality of connectors as shown in FIG. 2, namely, an output check connector 15,
Bipolar connector 16, hand switch connector 17
, active connector 18 and P (patient) play 1 to connector 19 are connected 32C. These connectors 15
19 to 19 include various treatment tools as shown in FIG.
Output check lead 20, Pibora tweezers 1-21
, a scalpel holder with a hand switch 22, an active scalpel holder 23, and a P (patient) plate 24 are connected, respectively. The output check lead 20 is used to check the output of the radiofrequency ablation device, and the bipolar tweezers 21
is used for suspicion, etc. The female holder 22 with a hand switch is used to turn on and off the high frequency output using a switch at hand.

The switch 1 to the switch 25 are connected to the output section 12 of the high frequency ablation device 11. In addition, the output connector section 14 includes
A detection section 26 is provided to detect that a treatment tool is inserted into the connector section. This detection section 26 is constituted by a switch structure 31 as shown in FIG. That is, the active electrode 32 of the active connector 18 is replaced with the tl switch electrode 33 by the insulating member 34. The movable switch electrode 33 is connected to the active electrode 3 by an insulating actuating member 35 provided on the active electrode 32 so as to be movable up and down.
2, and a switch operation is performed. Immediately, when the female holder 23 is inserted into the active connector 18, the female holder 23 pushes the actuating member 35 upward as shown in FIG. Along with this, the operating member 35
separates the movable switch electrode 33 from the active electrode,
Turn off the switch. FIG. 6 shows the switch structure 31 in the on state, whereas FIG. 7 shows the switch in the off state. In the switch-on state of FIG. 6, that is, the state in which the female holder 23 is not inserted into the active connector 18, if the female holder 22 with a hand switch is connected to the hand switch connector 17 at this time, the female holder 22 with a hand switch switch 22
A high frequency output is guided to the output terminal 22b according to the opening and closing of the terminal a.

The female holder 23 is inserted into the active connector 18,
When the switch structure 31 is in the off state,
The female holder 22 with a hand switch is electrically separated from the output section 12, and the high frequency output of the output section 12 is transmitted to the female holder 2.
Obtained only from 3. That is, when both the female holder 23 and the female holder 22 with a hand switch are inserted into the connector portion 14, the output is preferentially guided to the female holder 23. Therefore, even if a plurality of treatment instruments are connected to the connector portion 14, high-frequency output is supplied to only one treatment instrument, so there is no possibility of unintended output being produced, and treatment can be performed safely.

In the embodiment shown in FIG. 8, a photoelectric sensor (photointerrupter) 41 is provided as the detection section 26, for example, at the entrance of the active connector 18. The interrupter 41 includes a light-emitting cord 41a and a light-receiving element 41b, and detects the connection of the treatment instrument depending on whether the light from the light-emitting element 41a is interrupted. That is, when the female holder 23 is inserted into the active connector 18 as shown in FIG. 9, the light from the light emitting element 41a is blocked by the female holder 23, and the light receiving element 41b is turned off.

In response to the off signal of the light receiving element 41b, the output switching section 13 operates to guide the high frequency output to the active connector 18. At this time, the output system to other connectors is automatically cut off.

According to FIG. 10, a mechanical switch (
A microswitch) 42 is provided, for example, at the inlet of the active connector 18. This micro switch 42
is opened and closed by inserting and removing the scalpel holder 23, and insertion of the treatment tool is detected by opening or closing the switch. switch 4
In response to the opening/closing of 2, the output switching section 13 switches the high frequency output.

In the above description, the connector detector is provided on the active connector, but this detector may be provided on other connectors. Alternatively, the connector connection detection section may output signals according to the type of treatment instrument connected to the connector, and the high frequency output may be selected based on these outputs.

[Effects of the Invention] As explained above, since the detection section 26 is configured to guide high frequency output to one treatment tool by detecting insertion of the treatment tool, a plurality of treatment tools can be connected to the connector section. Even if the device is attached to the device, various high-frequency outputs will not be delivered to multiple treatment tools at the same time, allowing safe treatment at all times.
