Become.

FIG. 3 is a block diagram of the surgery support system according to the present embodiment.
The signal processing device 13 includes a signal generator 131, a duplexer 132, a mixer 133, an amplifier 134, an analog-digital converter (hereinafter referred to as “ADC”) 136, and a digital-analog converter (hereinafter referred to as “ADC”). 137).

The PC 14 includes a CPU (Central Processing Unit), a memory, an I / O interface, and a bus that connects these components to each other. The PC 14 implements an FFT unit 142, a bandpass filter 143, and a signal detection unit 144 by executing a predetermined computer program. The display 145 displays an image based on information input from the signal detection unit 144. The memory stores a table indicating the correspondence between the identification information of the tag devices 2A, 2B, and 2C and the light emitting units 122A, 122B, and 122C.

The signal generator 131 generates a scanning signal having a frequency of 13.56 MHz, for example, and inputs it to the duplexer 132. For example, the signal generator 131 generates a scanning signal based on control information acquired from a signal detection unit 144 described later.
The demultiplexer 132 divides the scanning signal into the transmission antenna 11 and the mixer 133 and inputs them. Here, the duplexer 132 divides the scanning signal so that, for example, the signal voltage of the scanning signal input to the transmitting antenna 11 is nine times the signal voltage of the scanning signal input to the mixer 133. Thereby, the scanning signal input to the transmission antenna 11 is transmitted from the transmission antenna 11 to the outside.

Also, the reception signal received by the reception antenna 121 is input to the mixer 133. This received signal includes an identification signal transmitted from the tag device 2A (2B, 2C) and a scanning signal transmitted from the transmitting antenna 11. The carrier wave of the identification signal is set to a frequency (13.56 ± 0.423 MHz) shifted by 423 kHz from the frequency of the scanning signal. Further, among the three tag devices 2A, 2B, and 2C, the tag device 2A placed in an area (hereinafter referred to as “communicable area”) capable of communicating with the processing device 1 via the receiving antenna 121. The identification signal transmitted from (2B, 2C) is included in the received signal. That is, the mixer 133 receives the identification signal transmitted from the tag device 2A (2B, 2C) placed in the region where the identification signal reaches the receiving antenna 121 among the three tag devices 2A, 2B, 2C. Included in the signal.

Then, the mixer 133 performs town conversion of the frequency of the received signal by mixing the scanning signal input from the duplexer 132 and the received signal input from the receiving antenna 121. Then, the mixer 133 inputs the received signal whose frequency is town converted to the amplifier 134. Note that a band cut filter for cutting a band in the vicinity of the frequency of the scanning signal may be interposed between the mixer 133 and the receiving antenna 121. In this case, the scanning signal component can be more effectively excluded from the received signal.

The amplifier 134 amplifies the reception signal input from the mixer 133 and inputs the amplified signal to the ADC 136. The ADC 136 converts a reception signal composed of an analog signal into a digital signal and inputs the digital signal to the PC 14.

In the PC 14, the FFT unit 142 performs a Fourier transform on the received signal input from the ADC 136. Here, the FFT unit 142 performs Fourier transform after correcting the received signal by the Hanning window function. Thereby, the noise component which arises with the Fourier-transform process by the FFT part 142 can be reduced.
Then, the FFT unit 142 inputs a signal obtained by Fourier transforming the received signal to the band pass filter 143.

The band pass filter 143 has a center frequency of 423 kHz. The band pass filter 143 removes the scanning signal component from the received signal by passing only the band of the identification signal. The identification signal that has passed through the bandpass filter 143 is input to the signal detection unit 144.

The signal detection unit 144 measures the strength of the identification signal, decodes the identification information included in the identification signal, and acquires the identification information. The signal detection unit 144 transmits a voltage signal in the form of a pulse train to the indicator 122 of the probe 12 via the DAC 137 based on the acquired identification information.

On the other hand, when the voltage signal is input from the processing device 1 (DAC 137), the light emitting unit 122A (light emitting unit 122B, light emitting unit 122C) blinks at the pulse period of the voltage signal.
Further, the signal detection unit 144 can distinguish between the position of the tag device (for example, the tag device 2A) placed in the communicable area and the position of the other tag devices (for example, the tag devices 2B and 2C). It is displayed on the screen of the display 145.

FIG. 4 is a block diagram of the tag device 2A (2B, 2C) according to the present embodiment.
The tag device 2 </ b> A (2 </ b> B, 2 </ b> C) is a passive type tag device, and includes an antenna 231, a communication unit 232, a signal processing unit 233, and a storage unit 234.
The antenna 231 is composed of, for example, a coil antenna. The antenna 231 functions as both a receiving antenna and a transmitting antenna.
The storage unit 234 is composed of a memory such as an EEPROM, for example, and identification information (for example, “ID1 (ID2, ID3)” in FIG. 4) corresponding to the tag device 2A (2B, 2C) in which the device itself is built. Remembers only one.

The communication unit 232 is configured by, for example, a dedicated integrated circuit. When receiving a signal from the processing device 1, the communication unit 232 activates the signal processing unit 233. Further, when there is an input of identification information from the signal processing unit 233, the communication unit 232 transmits a signal including the identification information to the processing device 1 through the antenna 231. Here, the signal transmitted from the antenna may be a sinusoidal signal having a frequency of 423 kHz, for example.
The signal processing unit 233 is configured by a dedicated integrated circuit, for example. When activated by the communication unit 232, the signal processing unit 233 inputs the identification information ID 1 (ID 2, ID 3) stored in the storage unit 234 to the communication unit 232.

<2> Operation Next, the operation of the surgery support system according to the present embodiment will be described.
First, the processing device 1 transmits a signal having a frequency of 13.56 MHz to the tag devices 2A, 2B, and 2C.
When the tag devices 2B and 2C do not exist within the communicable area of the processing device 1, the identification signals transmitted from the tag devices 2B and 2C do not reach the reception antenna 121 of the processing device 1. Therefore, the processing device 1 cannot receive the identification signal transmitted from the tag devices 2B and 2C.
On the other hand, when the tag device 2 </ b> A exists in the communicable area of the processing device 1, the identification signal transmitted from the tag device 2 </ b> A reaches the receiving antenna 121 of the processing device 1. Therefore, the processing device 1 can receive the identification signal transmitted from the tag device 2A.

In the processing device 1, as described above, the signal detection unit 144 measures the strength of the identification signal transmitted from the tag device 2A, decodes the identification information ID1 included in the identification signal, and acquires the identification information. To do. Here, the decoded identification information ID1 is held by the tag device 2A placed in the communicable area. Then, the signal detection unit 144 transmits a voltage signal in the form of a pulse train to the light emitting unit 122A (122B, 122C) corresponding to the acquired identification information ID1 (ID2, ID3). The signal detection unit 144 selects a transmission destination of the voltage signal with reference to a table indicating a correspondence relationship between the identification information ID1, ID2, and ID3 and the light emitting units 122A, 122B, and 122C.
In this way, when the processing apparatus 1 acquires the identification information ID1 (ID2, ID3), the light emitting unit 122A (122B, 122C) corresponding to the acquired identification information ID1 (ID2, ID3) included in the indicator 122 blinks. Let

Furthermore, the signal detection unit 144 changes the pulse interval of the voltage signal in a pulse train according to the intensity of the identification signal. Specifically, the signal detection unit 144 decreases the pulse interval and increases the blinking frequency of the light emitting unit 122A (122B, 122C) as the strength of the identification signal increases. On the other hand, the signal detection unit 144 increases the pulse interval and decreases the blinking frequency of the light emitting unit 122A (122B, 122C) as the strength of the identification signal is smaller.
Here, the greater the strength of the identification signal, the shorter the distance between the receiving antenna 121 and the tag device 2A (2B, 2C) placed in the communicable area. On the other hand, the smaller the intensity of the identification signal, the longer the distance between the receiving antenna 121 and the tag device 2A (2B, 2C) placed in the communicable area.

That is, the processing device 1 increases the blinking frequency of the light emitting unit 122A (122B, 122C) as the distance between the receiving antenna 121 and the tag device 2A (2B, 2C) is shorter. On the other hand, the processing device 1 decreases the blinking frequency of the light emitting unit 122A (122B, 122C) as the distance between the receiving antenna 121 and the tag device 2A (2B, 2C) is longer.
In the processing device 1, the relationship between the distance between the receiving antenna 121 and the tag device 2A (2B, 2C) and the blinking frequency of the light emitting unit 122A (122B, 122C) may be reversed. That is, as the distance between the receiving antenna 121 and the tag device 2A (2B, 2C) is shorter, the processing device 1 reduces the blinking frequency of the light emitting unit 122A (122B, 122C), and the receiving antenna 121 and the tag. The blinking frequency of the light emitting unit 122A (122B, 122C) may be increased as the distance from the device 2A (2B, 2C) is longer.

Thereby, the surgeon can use the tag device 2A (2B, 2C) existing in the communication area AR1 (AR2, AR3) with the receiving antenna 121 of the probe 12 from the blinking frequency of the light emitting unit 122A (122B, 122C). Can be visually grasped.

FIG. 5 is a diagram illustrating an example of the arrangement of the tag devices 2A, 2B, and 2C in the surgery support system according to the present embodiment. AR1, AR2, and AR3 in FIG. 5 indicate the communicable areas of the tag devices 2A, 2B, and 2C, respectively.
The tag devices 2A, 2B, 2C are arranged so as to surround the lesion C inside the lung B. Specifically, the tag device 2A is disposed above the lesion C, the tag device 2B is disposed on the left side of the lesion C, and the tag device 2C is disposed below the lesion C. The lesion C is located in an area surrounded by the three communicable areas AR1, AR2, AR3.

FIG. 6 is a diagram illustrating an example of use of the surgery support system according to the present embodiment.
It is assumed that the operator scans the probe 12 over the entire lung B. In this case, in the communicable area AR1, the first light emitting unit 122A of the probe 12 blinks. In the communicable area AR2, the second light emitting unit 122B of the probe 12 blinks. Then, in the communicable area AR3, the third light emitting unit 122C of the probe 12 blinks. Thereby, the surgeon can grasp the positions of the communicable areas AR1, AR2, AR3.
Then, the surgeon can relatively easily recognize that the lesion C exists in the area surrounded by the three communicable areas AR1, AR2, and AR3 in the lung B. Therefore, the operator can easily identify the position of the lesion C and perform an operation for removing the lesion C.

Further, in the surgery support system according to the present embodiment, the processing device 1 positions the tag device 2A (2B, 2C) holding the acquired identification information ID1 (ID2, ID3) in the patient P (for example, in the lung B). And a display mode corresponding to the identification information ID1 (ID2, ID3) of the indicator 122 is displayed on the screen of the display 145. Specifically, the PC 14 displays on the screen of the display 145 a graphics image of an organ to be operated (for example, lung B) and a graphics image indicating the positions of the tag devices 2A, 2B, 2C (for example, circles). Image). Further, identification information (for example, “ID1”, “ID2”, “ID3”) of each tag device 2A, 2B, 2C is also displayed on the screen of the display 145.

FIG. 7 is a diagram illustrating a usage example of the surgery support system according to the present embodiment.
As shown in FIG. 7, for example, when the surgeon brings the probe 12 close to the communicable area AR1 of the tag device 2A, a portion corresponding to the position of the tag device 2A in the image of the lung B on the screen of the display 145, The portion where the identification information ID1 of the tag device 2A is displayed blinks. Here, for example, when each of the light emitting units 122A, 122B, and 122C blinks in blue, yellow, and red as described above, the portion corresponding to the position of the tag device 2A is also blue on the screen of the display 145. And the portion where the identification information ID1 is displayed may be blinked in blue.
That is, on the screen of the display 145, the portion corresponding to the position of the tag device 2A (2B, 2C) and the portion where the identification information ID1 (ID2, ID3) is displayed are the emission colors of the light emitting units 122A, 122B, 122C.

<4> Summary After all, in the surgery support system according to the present embodiment, for example, in an endoscopic surgery, the operator inserts the probe (operation member) 12 into the body through the hole formed in the body wall of the patient P, and the indicator If the (display unit) 122 is held close to the lesion C, the surgeon can perform an operation while confirming the display mode of the indicator 122 in the surgical field by the endoscope. Further, in the operation by laparotomy or thoracotomy, if the probe 12 is inserted through an incision or a hole in the body wall and the indicator 122 is held close to the lesion C, the operator can perform the indicator 122 in the operative field by direct vision. Surgery can be performed while confirming the display mode.
The processing device 1 acquires identification information ID1 (ID2, ID3) included in the identification signal transmitted from the tag device 2A (2B, 2C) placed in the communicable area. The indicator 122 changes in display mode according to the identification information ID1 (ID2, ID3) of the tag device 2A (2B, 2C) acquired by the processing device 1. Therefore, if the three tag devices 2A, 2B, 2C are placed near the lesion C, the surgeon confirms the display mode of the indicator 122, so that each of the three tag devices 2A, 2B, 2C and the lesion The positional relationship with C can be easily grasped.

For example, the operator uses the endoscope apparatus 3 that places little burden on the patient P before the operation, and places three tag devices 2A, 2B, and 2C in the body of the patient P (lung B) so as to surround the lesion C. ). In this case, the operator easily identifies the communicable areas AR1, AR2, AR3 of the tag devices 2A, 2B, 2C surrounding the lesion C by confirming the display mode of the indicator 122 of the probe 12 during the operation. Therefore, the position of the lesion C can be easily specified. Accordingly, the time required for the surgeon to perform the operation can be shortened, so that the burden on the patient P can be reduced.

Further, in the surgery support system according to the present embodiment, the three tag devices 2A, 2A, and 3B are confirmed by checking which one of the first, second, and third light emitting units 122A, 122B, and 122C included in the indicator 122 emits light. The surgeon can easily confirm which of 2B and 2C exists in the communicable area.

<Modification>
(1) In the embodiment, when the processing device 1 acquires the identification information ID1 (ID2, ID3), the light emitting unit 122A (122B, 122C) corresponding to the acquired identification information ID1 (ID2, ID3) blinks. explained. However, the display mode of the indicator 122 when the processing apparatus 1 acquires the identification information ID1 (ID2, ID3) is not limited to this.

For example, when the processing apparatus 1 acquires the identification information ID1 (ID2, ID3), the light emitting unit 122A (122B, 122C) corresponding to the acquired identification information ID1 (ID2, ID3) included in the indicator 122 is turned on. There may be.
In this case, the signal detection unit 144 transmits a constant voltage signal to the light emitting unit 122A (122B, 122C) corresponding to the identification information ID1 (ID2, ID3).

Further, the processing device 1 may change the light emission intensity of the light emitting unit 122A (122B, 122C) in accordance with the distance between the receiving antenna 121 and the tag device 2A (2B, 2C).
In this case, the signal detection unit 144 changes the voltage value of the voltage signal according to the strength of the identification signal. For example, the signal detection unit 144 increases the voltage value of the voltage signal and increases the emission intensity of the light emitting unit 122A (122B, 122C) as the identification signal intensity increases. On the other hand, the signal detection unit 144 decreases the voltage value of the voltage signal and decreases the emission intensity of the light emitting unit 122A (122B, 122C) as the identification signal intensity decreases.

According to this configuration, the surgeon can visually grasp the distance between the receiving antenna of the operation member and the tag device existing in the communicable region from the light emission intensity of the light emitting unit.

(2) In the embodiment, an example in which the probe 12 has a rod shape and the indicator 122 is provided in the vicinity of the receiving antenna 121 provided at one end in the longitudinal direction has been described. However, the position of the indicator 122 is limited to this. It is not something.

FIG. 10 is a schematic side view of probes 512 and 612 according to this modification.
As shown in FIG. 10A, the probe 512 is rod-shaped. The probe 512 is provided with a receiving antenna 121 at one end in the longitudinal direction and a grip 124 at the other end in the longitudinal direction. An indicator 122 is provided in the vicinity of the grip portion 124 in the longitudinal direction of the probe 512. Here, “near” means being provided at a position separated from the grip portion 124 by 0 mm to 10 mm, for example.

According to this configuration, the indicator 122 is provided in the vicinity of the grip 124 provided at the other end opposite to the one end provided with the receiving antenna 121 in the longitudinal direction of the rod-like probe 512. . Thereby, the surgeon can grasp the position of the lesion C from the position of the receiving antenna 121 in the surgical field by checking the indicator 122 of the probe 512 inserted into the body outside the body of the patient P.

As shown in FIG. 10B, the indicator 122 may be provided at a substantially central portion in a portion other than the magnetic core portion 123 b and the grip portion 124 of the probe 612. In this configuration, the operator confirms the position of the lesion C from the position of the receiving antenna 121 in the operative field by checking the indicator 122 of the probe 612 inserted in the body outside or inside the body of the patient P (operative field). I can grasp it.
10A and 10B, the indicator 122 of the probes 512 and 612 inserted from the hole formed in the incision or the body wall in the operation by open abdomen or thoracotomy or the like is outside the patient P's body. Alternatively, the position of the lesion C can be grasped by checking in the body.

(3) In the surgery support system according to the embodiment, the example in which the probe 12 includes the transmission antenna 11 and the reception antenna has been described. For example, the probe 12 includes an antenna that functions as both transmission and reception. It may be.
FIG. 11 is a block diagram of a surgery support system according to this modification.
As shown in FIG. 11, in the surgery support system, the configuration of the signal processing device 413 is different from that of the embodiment.
The signal processing device 413 includes first and second duplexers 432 and 438. The probe 412 includes a transmission / reception antenna 421 that functions as both transmission and reception.
Second demultiplexer 438 divides the signal input from first demultiplexer 432 into antenna 421 and mixer 133 for input. The second demultiplexer 438 divides the signal input from the antenna 421 into the first demultiplexer 432 and the mixer 133 for input.

構成 According to this configuration, the configuration of the processing device 401 can be simplified.

(4) In the embodiment, when each of the plurality of tag devices 2A, 2B, 2C receives a signal transmitted from the transmission antenna 11 of the operation member 12, an example of transmitting identification information held by the own device has been described. . However, the tag device 2A (2B, 2C) receives a signal including identification information transmitted from the processing device 1, and compares the identification information received from the processing device 1 with the identification information held by itself. There may be.

FIG. 12 is a block diagram of the signal generator 131 according to this modification.
The signal generator 131 includes an interface 131a, a signal generation unit 131b, a storage unit 131c, and a communication unit 131d.
The interface 131a is composed of an RS232C connector, for example.
The storage unit 131c is configured by a memory such as an EEPROM, for example, and stores identification information (for example, “ID1”, “ID2”, and “ID3” in FIG. 12) of the tag devices 2A, 2B, and 2C. .
The signal generation unit 131b reads identification information from the storage unit 131c based on the control information acquired from the signal detection unit 144 through the interface 131a, and generates a scanning signal including the read identification information.

On the other hand, the tag device 2A (2B, 2C) has the same configuration as that of FIG. 4 and includes an antenna 231, a communication unit 232, a signal processing unit 233, and a storage unit 234. In the case of the tag device 2A (2B, 2C) according to this modification, the processing performed by the communication unit 232 and the signal processing unit 233 is different from the embodiment.
Specifically, the communication unit 232 demodulates the scanning signal transmitted from the processing device 1 and received by the antenna 231 and inputs the demodulated signal to the signal processing unit 233. Further, the communication unit 232 transmits the response signal input from the signal processing unit 233 to the processing device 1 through the antenna 231.
The signal processing unit 233 decodes the identification information included in the scanning signal input from the communication unit 232. Then, the signal processing unit 233 compares the identification information obtained by decoding with the identification information stored in the storage unit 234. If the two match, the signal processing unit 233 generates a response signal and generates the communication unit 232. To enter.

Next, the operation of the surgery support system according to this modification will be described.
FIG. 13 is an operation explanatory diagram of the surgery support system according to the embodiment, (a) is a sequence diagram, and (b) is a time chart showing the operation of the processing apparatus.
As shown in FIG. 13A, first, the processing device 1 broadcasts identification information (ID1) of the tag device 2A to the tag devices 2A, 2B, and 2C (steps S1, S2, and S3).
At this time, the tag devices 2B and 2C compare the identification information (ID1) transmitted from the processing device 1 with the identification information (ID2, ID3) held by the own device, and the identification information transmitted from the processing device 1. And the identification information held by the own device are determined not to match. In this case, the tag devices 2B and 2C do not transmit a response signal.
On the other hand, the tag device 2A compares the identification information (ID1) transmitted from the processing device 1 with the identification information (ID1) held by the own device, and holds the identification information transmitted from the processing device 1 and the own device. It is determined that the information matches. Then, the tag device 2A transmits a response signal ACK to the processing device 1 (step S4).

Next, the processing device 1 broadcasts the identification information (ID2) of the tag device 2B to the tag devices 2A, 2B, 2C (steps S5, S6, S7).
At this time, the tag devices 2A and 2C determine that the identification information (ID2) transmitted from the processing device 1 and the identification information (ID1, ID3) held by the own device do not match in the same manner as described above. In this case, the tag devices 2A and 2C do not transmit a response signal.
On the other hand, the tag device 2B determines that the identification information (ID2) transmitted from the processing device 1 matches the identification information (ID2) held by itself. Then, the tag device 2B transmits a response signal ACK to the processing device 1 (step S8).

Thereafter, the processing device 1 broadcasts the identification information (ID3) of the tag device 2C to the tag devices 2A, 2B, 2C (steps S9, S10, S11).
At this time, the tag devices 2A and 2B determine that the command information transmitted from the processing device 1 is not information corresponding to the own device in the same manner as described above. In this case, the tag devices 2A and 2B do not transmit a response signal.
On the other hand, the tag device 2C determines that the identification information (ID3) transmitted from the processing device 1 matches the identification information (ID3) held by itself. Then, the tag device 2C transmits a response signal ACK to the processing device 1 (step S12).

Thereafter, the processing device 1 and the tag devices 2A, 2B, and 2C repeatedly perform the above-described processing of step S1 to step S12.
Here, as shown in FIG. 13B, the processing device 1 broadcasts, for example, three types of identification information in a time-sharing manner.

FIG. 14 is a diagram illustrating a usage example of the surgery support system according to the present modification.
Here, the communicable area AR21 of the tag device 2A and the communicable area AR22 of the tag device 2B interfere with each other. Further, the communicable area AR2 of the tag device 2B and the communicable area AR3 of the tag device 2C interfere with each other.
Then, when the receiving antenna 121 of the probe 12 is located in an area that does not interfere with the communicable area AR22 in the communicable area AR21, only the light emitting unit 122A corresponding to the tag device 2A blinks.

Further, when the reception antenna 121 of the probe 12 is located in an area that interferes with the communicable area AR22 in the communicable area AR21, the first and second light emitting units 122A and 122B corresponding to the tag devices 2A and 2B, respectively. Both flash.
Furthermore, when the receiving antenna 121 of the probe 12 is located in an area that interferes with the communicable area AR23 in the communicable area AR22, both the light emitting units 122B and 122C corresponding to the tag devices 2B and 2C blink.

As described above, according to this configuration, when the receiving antenna 121 is arranged in a region where the communicable areas AR1, AR2, and AR3 of the three tag devices 2A, 2B, and 2C interfere with each other, the processing device 1 can distinguish and recognize the three tag devices 2A, 2B, and 2C. Therefore, even when the three tag devices 2A, 2B, and 2C are arranged close to each other to such an extent that the communicable areas AR1, AR2, and AR3 interfere with each other, the positions of the three tag devices 2A, 2B, and 2C Can be easily identified.

(5) In the surgery support system according to the modified example described in (4), the light emitting unit 122A (122B, 122C) is also used according to the distance between the receiving antenna 121 and the tag device 2A (2B, 2C). ) Blinking frequency and emission intensity may be changed.
Here, as shown in FIG. 13B, it is assumed that the processing device 1 broadcasts three types of identification information in a time division manner. In this case, the signal detection unit 144 may calculate the intensity of the identification signal input from the bandpass filter 143 using the relational expression (1) below.

Here, I (t) is the intensity of the identification signal input to the signal detector 144 at time t, I1ave, I2ave, and I3ave are average values of the intensity of the identification signals corresponding to the tag devices 2A, 2B, and 2C, K represents a parameter reflecting a period in which the signal detection unit 144 calculates the strength of the identification signal.

Here, the signal detection unit 144 calculates the average intensity value of the identification signals corresponding to the tag devices 2A, 2B, and 2C using the above equation (1). That is, the signal detection unit 144 performs an operation of dividing the integrated intensity value by the time for each time assigned to the tag devices 2A, 2B, and 2C for the identification signal input from the bandpass filter 143.

According to this configuration, even when the three tag devices 2A, 2B, and 2C are arranged close to each other so that the communicable areas AR1, AR2, and AR3 interfere with each other, the first, second, The relative positions of the receiving antenna 121 of the probe 12 with respect to the tag devices 2A, 2B, and 2C can be grasped relatively easily from the difference in the blinking frequency and emission intensity of the three light emitting units 122A, 122B, and 122C.

(6) In the embodiment, the identification of the communicable areas AR1, AR2, AR3 where the receiving antenna 121 is located is based on which of the first, second, and third light emitting units 122A, 122B, 122C emits light. The example to do was demonstrated. However, identification of the communicable areas AR1, AR2, AR3 where the reception antenna 121 is located, that is, identification of the tag devices 2A, 2B, 2C closest to the reception antenna 121 is not limited to this method.
For example, the probe 12 may include a display unit that displays identification numbers corresponding to the communicable areas AR1, AR2, and AR3. In this case, the surgeon can recognize the tag device 2A (2B, 2C) located closest to the receiving antenna 121 of the probe 12 by confirming the identification number displayed on the display unit of the probe 12. it can.
Further, an identification number corresponding to the communicable area AR1 (AR2, AR3) of the tag device 2A (2B, 2C) may be displayed on the screen of the display 145.

According to this configuration, the surgeon confirms the display content of the probe 12 and the display content of the display 145 to thereby confirm the tag device 2A (2B, 2B, 2D) that holds the identification information ID1 (ID2, ID3) acquired by the processing device 1. 2C) can be confirmed. Further, even if the number of tag devices increases, there is an advantage that the probe 12 does not need to be provided with light emitting portions having different emission colors corresponding to the respective tag devices. Furthermore, since the identification number can be displayed in a single color, there is an advantage that a plurality of types of light emitting units having different emission colors are not required.

(7) In the modified example (5), the blinking frequency and light emission of the first, second, and third light emitting units 122A, 122B, and 122C according to the distance between the receiving antenna 121 and the tag devices 2A, 2B, and 2C. The example which changes intensity | strength was demonstrated.
However, the index indicating the distance between the receiving antenna 121 and the tag devices 2A, 2B, and 2C is limited to the blinking frequency and light emission intensity of the first, second, and third light emitting units 122A, 122B, and 122C. It is not a thing. For example, the light emission color of each light emitting unit (first, second, third light emitting unit 122A, 122B, 122C) changes according to the distance between the receiving antenna 121 and the tag devices 2A, 2B, 2C. It may be.

For example, when the receiving antenna 121 is located in the peripheral part of the communicable areas AR1, AR2, AR3, the light emitting unit emits purple light, and the receiving antenna 121 is connected to the tag devices 2A, 2A, AR3 in the communicable areas AR1, AR2, AR3. You may make it light-emit in red, green, and yellow, so that 2B and 2C vicinity is approached. In this case, for example, the first, second, and third light emitting units 122A, 122B, and 122C may have two types of light emitting elements having different emission colors. Specifically, the first light emitting unit 122A has a light emitting element that emits red light and a light emitting element that emits purple light, and the second light emitting unit 122B emits a light emitting element that emits green light and purple light. It is sufficient to have a light emitting element that can be used. The third light emitting unit 122C may have a light emitting element that emits yellow light and a light emitting element that emits purple light. And in 1st, 2nd, 3rd light emission part 122A, 122B, 122C, according to the distance between the receiving antenna 121 and tag apparatus 2A, 2B, 2C, the ratio of the emitted light intensity of two types of light emitting elements Can be changed. Alternatively, the two types of light emitting elements may be configured to alternately emit light, and the ratio of the light emission time of each light emitting element may be changed.

According to this configuration, the surgeon grasps the distance between the receiving antenna 121 and each tag device 2A, 2B, 2C based on the emission colors of the first, second, and third light emitting units 122A, 122B, 122C. can do.
