Description

[Detailed Description of the Invention] (a) Field of Industrial Application This invention relates to a device for recognizing the type of attachment of a treatment electrode that performs heat treatment by applying a high frequency voltage to cancer tissue, for example.

(b) Conventional technology For treatment electrodes, such as high-frequency treatment electrodes, electrodes with different diameters are usually selected depending on the location of the cancer tissue, so that they can most efficiently exert a heating effect on the cancer tissue. It is then attached to the device body (electrode mounting body). When selecting electrodes, there are cases in which electrodes are selected for body parts where cancerous areas are located, such as the neck, abdomen, and arms, and cases in which electrodes are selected according to the superficial and deep positions of cancer tissue in body parts. There is. In the latter case, for example, if the cancer tissue is located on the abdominal surface side (shallow position) of the body, it is possible to select a small diameter electrode on the abdomen side and a large diameter electrode on the back side and attach them in opposing fashion. , is set so that the heating effect acts most efficiently on the cancer tissue.

Normally, in this selection operation of therapeutic electrodes, the operator visually checks a large number of pre-prepared electrodes with different diameters, selects and attaches the electrode that is recognized to be suitable for the cancerous area. It is being done.

(c) Problems to be solved by the invention Currently, for example, high-frequency thermotherapy devices are not equipped with any means for determining the type of treatment electrode attached. For this reason, in the method in which the operator visually selects and attaches the electrodes, there are many electrodes with similar diameters, so the operator may make a mistake in selecting the electrode and, without realizing this error, attach the electrode to the mount. It may be fixed to (the main body of the device). Fixing the electrode is
Since the electrodes are firmly fixed with bolts in consideration of poor electrical conduction, if a faulty electrode is discovered after treatment has begun, it will not only take time to replace the electrodes, but it may also be disadvantageous, such as not being able to provide proper treatment. It was hot.

This idea solves the above problems,
It is an object of the present invention to provide a device for recognizing the attachment type of a therapeutic electrode that automatically determines the type of the attached electrode and prevents incorrect attachment of the electrode.

(d) Means and action for solving the problem In order to achieve this objective, the device for recognizing the attachment type of the therapeutic electrode of this invention has the following configuration.

The device for recognizing the attachment type of a therapeutic electrode is composed of a therapeutic electrode having a mounting shaft, and an electrode mounting body into which the mounting shaft of the therapeutic electrode is removably fitted, and the mounting shaft of the therapeutic electrode is attached to an appropriate position. A type specifying means for specifying the electrode type is provided, and an electrode discriminating means for detecting electrode type information from the type specifying means is provided on the electrode mounting body side.

In the apparatus for recognizing the attachment type of therapeutic electrodes having such a configuration, each type of electrode is provided with type specifying means (for example, a type code using a black and white pattern) for specifying the type of each electrode. On the other hand, on the electrode mounting body side, electrode discrimination means (for example, a receiving/emitting element) for detecting a type code is provided. When installing the electrode, fit the electrode mounting shaft into the electrode mounting body (device main body) side. At this time, the type code of the mounting shaft is positioned corresponding to the receiving/emitting element of the electrode mounting body. Here, the light emitting part projects light onto the type code, and the light receiving part receives this reflected light, thereby automatically detecting the type of the attached electrode. Display that there is such a thing. As a result, the operator knows whether the electrodes he or she has confirmed are correct, fixes the electrodes, and then moves to the treatment stage. Therefore, even if the operator selects the wrong electrode and attaches it (fitted), the operator can immediately recognize the error in selection and remove the electrode that has not yet been fixed and has only been fitted. can be replaced extremely easily and appropriate treatment can be given.

A mounting groove portion 12 is recessed in the upper surface of 1. On the other hand, the electrode mounting body 2 is a cylindrical body, and is fitted into the cylindrical cover case 3 with one end portion (mounting surface portion) 21 exposed. This mounting surface portion 21 includes
Mounting hole 2 for inserting the electrode mounting shaft 11
2 is open. In addition, this protruding mounting surface portion 21
and the opening surface of the cover case 3 are connected by a flexible stretchable material 31, and are set to allow angular displacement of the electrode mounting body 1. Furthermore, a power switch portion 32 is provided at a suitable location on the outer surface of the cover case 3.
and a plurality of lighting lamp/switch units that specifically display the attached electrodes, such as the shoulder electrode switch 3.
3. Abdominal electrode switch 34, arm electrode switch 3
5. A neck electrode switch 36 and a buzzer 37 are provided to notify you of incorrectly attached electrodes. These switch sections 32, 33, 34, 35, and 36 and the buzzer 37 are electrically connected to a control circuit section, which will be described later.

FIG. 1 is an enlarged sectional view of essential parts showing the attachment relationship between the electrode 1 and the electrode attachment body 2. FIG.

The electrode mounting body 2 is provided with a stopper shaft 23 that moves up and down orthogonally from above with respect to the mounting hole 22, and a high frequency power supply section 24 that projects from the lower part of the mounting hole 22. This stopper shaft 23 is connected to a drive motor (not shown) via a transmission means (pulley, belt) 25, and moves in and out of the groove 12 of the electrode mounting shaft 11 to fix and release the electrode 1. .

Further, the high frequency power supply section 24 has a lead wire 26
It is connected to a high frequency power source (not shown) via the stopper shaft 23, supports the lower surface of the electrode mounting shaft 11 that is pressed downward by the stopper shaft 23, and is electrically connected.

The feature of this invention is that the electrode mounting shaft 11 is provided with an electrode type identifying means 4, and the electrode mounting body 2 is provided with an electrode determining means 5 for detecting the type of the attached electrode.

As shown in FIG. 2, the electrode type specifying means 4 is constructed by forming a bar code 41 on the tip end surface of the electrode mounting shaft 11. In the embodiment, the barcode 41 has black and white optical patterns in 4-bit areas 42, 43, 44, and 45, and is a binary coded decimal number (BCD).
As shown in FIG. 4, 16 types of electrodes (for example, shoulder electrodes, arm electrodes, abdominal electrodes, neck electrodes, etc.) can be specified.

The electrode discriminating means 5 includes a light receiving section (phototransistor) 51 and a light emitting section (light emitting diode) 52 on the bottom surface of the mounting hole 22 of the electrode mounting body 2, that is, at a position corresponding to the insertion end surface of the electrode mounting shaft 11. (See Figure 1). Receiving/emitting part 5
As shown in FIG. 3, four pairs of barcodes 1 and 52 are provided corresponding to each area 42, 43, 44, and 45 of the barcode 41, respectively. The receiving/emitting sections 51 and 52 are connected to a control circuit section (processor) which will be described later.

In the embodiment, an example was shown in which the receiving/emitting parts 51 and 52 were arranged directly on the bottom of the mounting hole part 22, but in actual implementation, an optical fiber was used and the receiving/emitting parts 5
1 and 52 may be set at positions spaced apart from the mounting shaft 11. In this case, the receiving/emitting sections 51 and 52 are not affected by surrounding electromagnetic induction, and the discrimination function is further improved.

FIG. 5 is a circuit block diagram of an apparatus for recognizing an attached electrode of a therapeutic electrode according to an embodiment.

For example, if the operator selects the shoulder electrode 1 and fits it into the electrode mounting body (attachment hole 22) 2, the operator selects the shoulder electrode 1, which is attached to the lighting lamp switch part disposed in the cover case 3, for example, the shoulder electrode. Turn on the switch 33. The encoding circuit unit 61 encodes the turned-on shoulder electrode, that is, the designated shoulder electrode,
The coded signal is output to the coincidence circuit section 62.

On the other hand, the discrimination reading section (receiving/emitting section 51, 52)

The matching circuit unit 62 has a function of determining whether or not the attached electrode 1 matches the operator's designated electrode (shoulder electrode in this case) based on the input data, and also has a function of determining whether or not the attached electrode 1 matches the electrode specified by the operator (in this case, the shoulder electrode). A switch that also functions as a lighting lamp (in this case, the function of lighting the shoulder electrode switch 33) when a match is obtained between the read data and the encoded data, and a buzzer when the above data do not match. 3
7.

FIG. 8 is an enlarged sectional view of a main part showing another embodiment of the electrode type specifying means 4 and the electrode discriminating means 5. FIG.

In the previous embodiment, the barcode 41 is used as the electrode type specifying means 4, and the receiving/emitting section 51 is used as the discriminating means 5.
52 was shown, but in this example,
A hole pattern 46 is used instead of the bar code 41, and a micro switch 53 is used instead of the receiving/emitting sections 51 and 52.

As shown in FIG. 8, the micro switch 53
is arranged at the bottom of the mounting hole 22, and this micro switch 53 is connected with a detection pin 54 that protrudes into the mounting hole 22.
is constantly biased in the direction of the mounting hole 22 by a spring 55. On the other hand, as shown in FIG.
A hole pattern 46 corresponding to 1 is formed. This hole pattern 46 corresponds to 4 of the barcode 41.
By forming pin holes 46a corresponding to the areas,
Settings are made so that 16 types of electrodes as shown in FIG. 11 can be specified. That is, as shown in FIG. 10, four detection pins 54 are protruded in correspondence with the spacing between the pin holes 46a, and the four detection pins 54 are fitted into the pin holes 46a according to the hole pattern 46. Alternatively, the electrode type is determined by turning on the micro switch 53 by the pressing force of the detection pin 54 that does not fit.

In the apparatus for recognizing the attachment type of a therapeutic electrode having such a configuration, the operator selects the electrode 1 that is considered to be suitable for the cancerous area, and inserts the attachment shaft 11 into the attachment hole 22.
Fits in. If the fitted electrode 1 is a shoulder electrode, the operator turns on the shoulder electrode switch 33.

In this state, the barcode 41 is positioned corresponding to the receiving/emitting parts 51 and 52, and the respective light emitting parts 5
2 to each area of barcode 4 42, 43, 44,
45, each light receiving section 51 receives the reflected light, and the type information of the inserted electrode 1 is read. The type information of this attached (fitting) electrode is output to the matching circuit section 62. On the other hand, when the operator turns on the shoulder electrode switch 33, the encoding circuit section 61 outputs the encoding information of the designated shoulder electrode to the matching circuit section 62. put it here,
The matching circuit section 62 compares the attached electrode information read by the receiving/emitting sections 51 and 52 with the shoulder electrode encoding information specified by the operator using a switch, and determines whether the attached electrode 1 is specified by the operator. It is determined whether the selected electrode matches the selected electrode. In this case, since the attached electrode is a shoulder electrode and the encoded information specified by the operator is also a shoulder electrode, a match is determined.
The shoulder electrode switch 33 is turned on. By this lighting, the operator knows that the electrode selection is correct, lowers the stopper shaft 23 to fix the electrode 1, and begins treatment.

Conversely, even though the attached electrode 1 is an abdominal electrode, the operator does not switch the shoulder electrode switch 3.
3 is turned on, it is determined that there is a mismatch, and the buzzer 37 sounds. Thereby, the operator can quickly learn that the electrode 1 that he has selected is not the shoulder electrode, and can replace the electrode 1 with the shoulder electrode.

Note that the read coded information can be stored in a built-in memory, and it is also possible to output later what type of electrode the treatment was performed with.

(F) Effects of the invention In this invention, as described above, a type identification means for identifying the type of electrode is provided on the electrode mounting shaft, and an electrode identification means is provided on the electrode mounting body to detect specific information of the type identification means. Since the means is provided, the type of the attached electrode can be automatically recognized by simply inserting the electrode mounting shaft into the electrode mounting body.

Therefore, even if the operator selects an incorrectly selected electrode and fits it into the electrode mounting body, the operator will not be able to quickly recognize the selection mistake; at this point, the electrode will simply fit into the electrode mounting body. Since the electrode has only been inserted into the body and is not fixed yet, it has the excellent effect of achieving the purpose of the invention, such as being able to extremely easily replace the electrode and perform appropriate treatment.
