DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Do this in the following order: 1. Embodiment (Example of determining the type of connected electrical medical device using a relay device) 2. Variations Modification 1 (Example of a case where a relay device and an electrical medical device are used for discrimination) Modification 2 (Example in which the discrimination unit is provided in the relay device instead of in the power supply device) 3. Other Modifications

[0011] <1. Preferred embodiment> [Overall configuration of electrical medical device system 5] FIG. 1 is a schematic diagram showing an example of the overall configuration of an electric medical device system 5 according to an embodiment of the present disclosure. The electrical medical device system 5 is used to perform treatment inside the patient's body. Treatment, etc. refers to medical treatment such as ablation (cauterization) of the affected area, and The "power supply method" in the present disclosure includes the electrical medical device system of the present disclosure. These are embodied in the following, so they will be explained together below.

[0012] The electrical medical device system 5 includes a power supply device 3 and one or more relay devices 6 (see FIG. 1 ). In the example shown in FIG. 1, there are three relay devices 6a, 6b, and 6c, and an electric medical device connected to each of the relay devices 6. The device 1 (in the example of FIG. 1, three electric medical devices 1a, 1b, and 1c) is provided. When performing treatment using the electrical medical device system 5, for example, the return electrode 4 is also Used.

[0013] The control system configured by the power supply device 3 and the relay device 6 is the "electric This corresponds to a specific example of a "medical device control system."

[0014] (Electromedical Device 1) The electric medical device 1 is a device used when performing the above-mentioned treatment, etc. The electrical medical device 1 includes a body 11 and one or more electrodes 111. For example, it is composed of an ablation catheter, an electrode needle, an electric scalpel, etc.

[0015] The electrode 111 is disposed near the tip of the elongated device body 11. In the example, one or more electrodes 111 are provided near the tip of the device body 11 . Specifically, in the electrical medical device 1a, one electrode 1 is provided near the tip of the device body 11. In the electric medical device 1b, the distal end side of the device body 11 is divided into two parts. The electrode 111 is located near the tip of each branch (a total of two electrodes 111). In the electric medical device 1c, a plurality of A number of electrodes 111 are provided.

[0016] That is, the electrical medical device 1a has a structure in which an electrical current is generated between one electrode 111 and a return electrode plate 4 (another electrode). The electric medical devices 1b and 1c are monopolar devices that are used for treatment, etc. In this case, the treatment is performed between a plurality of electrodes 111, which is a bipolar type. Treatment is performed between multiple electrodes on an electrical medical device and a return electrode (another electrode). It may be of a monopolar type.

[0017] (Relay device 6) The relay device 6 relays between the electric medical device 1 and the power supply device 3. The receiver 6a relays between the power supply unit 3 and the set including the electric medical device 1a and the return electrode plate 4. The relay device 6b relays between the electric medical device 1b and the power supply device 3. The relay device 6c , relaying between the electric medical device 1 c and the power supply unit 3 .

[0018] The relay device 6a has an input terminal Tin61 connected to the power supply device 3 via a connection cable C1. and an output terminal Tout62 to which the electric medical device 1a is connected via a connection cable C2. and an input terminal Tin62 to which the return electrode 4 is connected via a connection cable C3. The relay devices 6b and 6c are connected to the power supply device 3 via a connection cable C1. The power terminal Tin6 is connected to the electrical medical device 1b or the electrical medical device 2b via the connection cable C2. In the example of FIG. 1, the output terminal Tout6 is connected to the input terminal 1c. As shown, three connection cables C1 are individually connected to the relay devices 6a, 6b, and 6c. The selected connection cable C1 is connected to the output terminal Tout3 (power Po ut, etc. are output). In other words, when the electric medical device 1 is in use, Only the relay device 6 corresponding to the electrical medical device 1 to be used is connected to the power supply unit 3. .

[0019] For example, the shapes of the output terminals Tout6 and Tout62 may be different for each of the relay devices 6a, 6b, and 6c. By making the terminals different from each other, it is possible to prevent the electric medical device 1 from being connected incorrectly to the relay device 6. You can do so.

[0020] Each of the input terminals Tin6 and Tin61 corresponds to a specific example of an “input unit” in the present disclosure. The output terminals Tout6 and Tout62 are each a specific example of an “output unit” in the present disclosure. It supports.

[0021] An example of a detailed configuration of relay device 6 will be described later (FIGS. 2 to 5).

[0022] (Power supply unit 3) The power supply device 3 is a device that supplies power Pout (e.g., radio frequency (RF) ) to the electrical medical device 1. Specifically, the power supply unit 3 has an output Electrical power is supplied from the terminal Tout3 through the connection cable C1, the relay device 6 and the connection cable C2. Power Pout is supplied to the medical device 1.

[0023] An example of a detailed configuration of the power supply device 3 will be described later (FIGS. 2 to 5).

[0024] (Return electrode 4) The return electrode 4 is attached to the body surface of a patient 9 during treatment. In this example, when a treatment or the like is performed using the electrical medical device 1a, the electrode 111 and the return electrode 4 are Between these, high frequency current is applied (power Pout is supplied).

[0025] [Detailed configuration of power supply unit 3 and relay device 6] Next, referring to FIG. 1 and FIG. 2 to FIG. 5, detailed configurations of the power supply device 3 and the relay device 6 will be described. An example will be described.

[0026] FIG. 2 shows a detailed configuration example of the electric medical device system 5 (a power supply device 3 and a relay device 6 An example of connecting an electric medical device 1a and a return electrode 4 via a is shown in the block diagram. It represents.

[0027] (Power supply unit 3) As shown in FIG. 2, the power supply device 3 includes an input unit 31, a power supply unit 32, a control unit 33, and a display unit 3 4 and a discrimination unit 35.

[0028] The input unit 31 receives various set values ​​or instruction signals (operation signals) for instructing a predetermined operation. The operation signal is generated by the operator of the power supply device 3 (e.g., an engineer, etc.) pressing a button. The input unit 31 outputs the signal to the control unit 33 in response to the operation of the input unit 31. Some of these are not entered in response to an operator's operation, but rather, for example, when a product is shipped. Alternatively, the above may be set in advance in the power supply device 3.

[0029] The power supply unit 32 outputs power Pout under the control of the control unit 33. It is configured using a predetermined power supply circuit (for example, a switching regulator, etc.). For example, when the power Pout is high-frequency power, the frequency of the power Pout is 450 kHz to 550 kHz. kHz (preferably 500 kHz).

[0030] The control unit 33 is a part that controls the entire power supply device 3 and performs predetermined arithmetic processing. The control unit 33 and the discrimination unit 35 are configured using, for example, a microcomputer. The control unit 33 controls, for example, the supply operation of the power Pout in the power supply unit 32 and the display unit 34. and the display operation in the display area.

[0031] The display unit 34 is a part (monitor) that displays various information and outputs it to the outside. The display unit 34 is a display of various types (for example, a liquid crystal display or a CRT (Cathode Ray Tube)). OLED (Electro-Luminescence) displays, etc.) It is composed of the following:

[0032] The determination unit 35 uses the relay device 6 connected to the power supply device 3 (output terminal Tout3) to The relay device 6 is connected to the electrical medical device 1. The determination unit 35 communicates with the information storage unit 61 in the relay device 6 and with the control unit 33. The discrimination unit 35 inputs and outputs various information. Details of the discrimination made by the discrimination unit 35 will be described later. (Figures 4 and 5).

[0033] (Relay device 6) The relay device 6 (relay device 6a) further includes an information storage unit 61.

[0034] The information storage unit 61 stores discrimination information 610, which is information used for discrimination by the discrimination unit 35. The discrimination information 610 is stored in the relay device 6. Bit information I, which is specified according to the type of device 1 and is specified mechanically or electrically If the discrimination information 610 includes electrically defined bit information IB, In this case, the information storage unit 61 is configured using, for example, memories (storage units) using various storage methods. If the discrimination information 610 includes mechanically defined bit information IB, the information is stored. The holding portion 61 and the discrimination information 610 are respectively configured, for example, in accordance with the mechanical structure shown in FIG. This will be more easily realized.

[0035] FIG. 3 shows a detailed configuration example of a part related to the discrimination according to the present embodiment (discrimination information 610, A schematic diagram of an example of a configuration that includes mechanically defined bit information IB is shown below. It is shown in the road diagram.

[0036] In the example of FIG. 3, the information storage unit 61 stores discrimination information including mechanically defined bit information IB. The information 610 includes three switches Sa, Sb, and Sc. The information indicating the states (on or off state) of the switches Sa, Sb, and Sc is the discrimination information 61. It corresponds to bit information IB as 0 (information of each bit: "0" or "1"). The switch Sa is connected to a wiring La connected to the discrimination unit 35 in the power supply device 3 and to a wiring La connected to the ground. The switch Sb is disposed between the wiring LG connected to the discrimination unit 35. The switch Sc is disposed between the wiring L and the discrimination unit 35. The wires La, Lb, and Lc are connected to the power supply VD. The wiring through resistor R is connected separately.

[0037] In the example of Figure 3, the switches Sa and Sb are both set to the off state (open wiring). The switch Sc is set to the ON state (wire short state). As shown by the dashed arrow in Figure 3, the power supply VD is connected to the resistor R, the wiring Lc, and the switch Sc and a current ID of a certain value or more (for example, a current of just under 1 [mA]) flows through the wiring LG. ) flows toward the ground. On the other hand, the wires La, Lb and the switches Sa, Sb A current ID of a predetermined value or more does not flow through each of the switches Sa, Sb, and Sc. Even in this state, the power supply VD is connected to the inside of the discrimination unit 35 (for example, an input resistor of 10 [MΩ]). A very small current less than a certain value (for example, a current of just under 1 μA) flows through the capacitor.

[0038] The determination unit 35 determines bit information IB (see FIG. In the example of 3, the contents of the three-bit bit information IB) are determined. That is, the switches Sa, When Sb and Sc are set to the on state, the voltage state on the wires La, Lb, and Lc is Since the bit becomes the ground level ("L (low) level), the discrimination unit 35 The switch information IB is set to "0". The switches Sa, Sb, and Sc are set to the off state. When the voltage state on the wiring La, Lb, and Lc is the power supply VD level ("H (high) level), Therefore, the discriminator 35 determines that the bit information IB of that bit is "1". Therefore, in the example of Figure 3, when the voltage states on the wires La, Lb, and Lc are shown in order, there are three bits. The bit information IB of the packet is determined as "110". The order of the bits is as shown in Figure 3. The contents of the discrimination information 610 including the bit information IB are not limited to the above example and can be set arbitrarily. , for each type of electrical medical device 1 connected to the relay device 6 (type of relay device 6), is set to.

[0039] FIG. 4 shows an example of a truth table Tb used in the determination according to the present embodiment. Specifically, the truth table Tb is a table of the contents of the discrimination information 610 (bit information IB) and the power supply device FIG. 5 shows an example of a correspondence relationship between the output state of the power Pout from the electric medical device 3. 13 shows an example of information included as the type of device 1.

[0040] In this embodiment, the power supply device 3 (power supply unit 32) performs discrimination using the relay device 6 (discrimination unit 3 The electrical medical device 1 connected to the relay device 6 obtained by the determination in 5) In other words, the power supply device 3 outputs the power Pout in an output mode according to the type of relay. The devices 6 (electrical medical devices 1) are connected to each relay device 6 in different output modes depending on the type of device 6. The power supply device 3 outputs power Pout to the electric medical device 1. The output power Pout is input to the input terminal (input terminal Tin6 or input terminal via the output terminal (output terminal Tout6 or output terminal Tout62) The output is then output to the connected electrical medical device 1. A type of electrical medical device 1 that is operated within the range of a type of electrical medical device 1 The setting includes the setting value set by the user.

[0041] For example, as shown in FIG. 4, the discrimination unit 35 determines whether or not the discrimination information 610 is correct based on the contents of the discrimination information 610. The connection status (connected or unconnected) of the relay device 6 to the power supply device 3 and the relay device 6 The type of electrical medical device 1 connected to the electrical medical device is determined. As an example of the type of 1, as shown in FIG. 5, the output format of the electric medical device 1 and , the operating mode when using the electrical medical device 1 and the maximum output of the electrical medical device 1 The information includes at least one of the following: output type, operation mode, and maximum power. A specific example of the contents at high output power is as follows, as shown in FIG. Output type: Unipolar / Bipolar Operation mode: coagulation mode / incision mode Maximum output power: 50[W] / 100[W] / 200[W] / other

[0042] In addition, the output state (output) of the power Pout according to the contents of the discrimination information 610 (bit information IB) Specific examples of the modes are as follows, as shown in the truth table Tb of FIG. In Figure 4, the power Pout output status is shown. Also shown are the following: "Output Mode A" to "Output Mode G" have the above-mentioned output formats, operation modes, and Each item, such as maximum output power, is set individually. IB="000": Output mode A IB="001": Output mode B IB="010": Output mode C IB="011": Output mode D IB="100": Output mode E IB="101": Output mode F IB="110": Output mode G IB="111": (Repeater 6: Not connected)

[0043] [Operation and Effects] (A.Basic movement) In the electrical medical device system 5, treatment or the like is performed on the affected area of ​​the patient 9. When performing the procedure, the device body 11 is inserted into the body of the patient 9 from its tip side. A power supply unit 3 supplies power Pout( For example, high-frequency power) is supplied to the affected area of ​​the patient 9, causing Joule heating. Treatment etc. is carried out.

[0044] In the conventional general electrical medical device system, the electrical medical device itself has no identification. The device contains identification information (e.g., information indicating the type of electrical medical device) The type of electrical medical device (output specifications such as maximum output power) is determined using However, if identification information is embedded in a disposable electrical medical device, This can lead to increased costs and size of medical devices. By providing multiple types of connectors (power output terminals) in Although there are variations available, the power supply unit case becomes larger and the output specifications become The types of connectors available are limited to the types of connectors available, which reduces convenience.

[0045] In this way, in general electrical medical device systems, the aim is to reduce size while improving convenience. It can be said that it is difficult to achieve this.

[0046] (B. Discrimination processing, etc.) Therefore, in the electric medical device system 5 of this embodiment, the discrimination unit 35 uses the relay device 6. The type of the connected electric medical device 1 is determined by using the above. In terms of form, it is not a disposable type (throw-away type) electrical medical device1 but a non-disposable type. Such a determination is made by using a portable (reusable) relay device 6. The determination process and the like according to the present embodiment will be described in detail with reference to FIG. 6 in addition to FIG. 1 to FIG. do.

[0047] FIG. 6 is a flow chart showing an example of the determination process according to the present embodiment.

[0048] In the series of processes shown in FIG. 6, when the power supply device 3 is started, the discrimination unit 35 first checks the bit The information IB (discrimination information 610) is read (step S11). Next, the discrimination unit 35 Whether the contents of the read bit information IB are other than IB=“111” (relay device 6 Then, it is determined whether the IB is in a connected state (step S12). If it is determined that the state is other than that (the relay device 6 is connected) (step S12: Y ), and the process proceeds to step S17, which will be described later.

[0049] On the other hand, if it is determined that IB=“111” (repeater 6 is not connected), (Step S12: N), the device enters a standby state for a predetermined time (for example, about a few seconds) (Step After that, the determination unit 35 executes reading of the bit information IB again (step S13). S14), and it is determined again whether IB is other than "111" (step S1 5) If it is determined that IB is other than "111" (the relay device 6 is connected), (Step S15: Y), proceed to step S17 described later. On the other hand, if IB="111" If it is determined again that the relay device 6 is in an unconnected state (step S15: N), a message prompting the connection of the relay device 6 is output (for example, a message is displayed on the display unit 34). After that, the process returns to step S13 (waiting for a predetermined time) (step S16). The system returns to the normal operating state.

[0050] In the above-mentioned step S17, the discrimination unit 35 determines whether or not the bit information IB is Then, the output mode is set based on the truth table Tb (step S17). 3 (power supply unit 32) in response to an operation signal (operation by an operator) output from the input unit 31 Operates in the set output mode (power Pout output is turned on or in standby mode) Then, a de-energization operation is performed (step S18).

[0051] Next, the determination unit 35 determines whether the content of the bit information IB has changed since then. If it is determined that the content of the bit information IB has not changed, If the content of the bit information IB is changed (step S19: N), the process returns to step S18. When it is determined that the power Pout is output (step S19: Y), the determination unit 35 It is determined whether the power supply is in a power-on state (power-on state) (step S20). During the output period of Pout (power-on period), the bit information is This is because the contents of the IB may change.

[0052] When it is determined that the power Pout is in the output state (output period) (step S20: Y ), and the process returns to step S18. ,Because there is a possibility that the contents of the bit information IB may change due to noise signals when the power is turned on, The determination based on the contents of the bit information IB (resetting of the output mode in step S17) is performed. Do not perform this action.

[0053] On the other hand, if it is determined that the power Pout is not in an output state (output is stopped), Step S20: N) is as follows. That is, in this case, the discrimination unit 35 The bit information IB is read (step S21), and if IB is other than "111", It is judged again whether the relay device 6 is in a connected state or not (step S2 2) This is because the change in the content of the bit information IB is caused by the replacement of the relay device 6 connected to the power supply device 3. In order to determine whether the change in contents is due to the work of temporarily removing relay device 6, This is the case.

[0054] If it is determined that IB is other than "111" (repeater 6 remains connected) If the result is "Y" at step S22, the process returns to step S18. The change in the contents of the information IB is not a change in contents due to replacement of the relay device 6 (for example, a change in contents due to a change in contents other than when the power is turned on). (The content change is due to other noise signals.) Therefore, in this case, Discrimination based on the contents of the bit information IB after the change (resetting of the output mode in step S17) But it doesn't get executed.

[0055] On the other hand, if it is determined that IB=“111” (transition to the disconnected state of relay device 6), If the answer is NO (step S22: N), the process proceeds to step S13 (a standby state for a predetermined period of time). In this case, the change in the content of the bit information IB indicates the replacement of the relay device 6 (removing the relay device 6 once). The change in contents was determined to be due to the removal of the power supply. In this way, the determination unit 35 waits until the output of the power Pout is stopped. If it is detected that the content of the bit information IB (discrimination information 610) has changed during the stop period, In this case, the determination unit 35 performs the following process. After passing through "S22:N" → S13 → S14 → "S15:Y", the changed In this case, the determination based on the contents of the bit information IB (step S17) is performed. In this case, the message prompting the connection of the relay device 6 is not output (step S16), and the device remains in a standby state. (Step S13). Note that if you turn off the power and do not reset the device, Even if the relay device 6 is replaced, there is no problem in driving the relay device 6.

[0056] This concludes the explanation of the series of processes shown in FIG.

[0057] (C. Actions and Effects) In this manner, in this embodiment, a relay that relays between the electric medical device 1 and the power supply unit 3 is provided. An electrical medical device connected to the relay device 6, obtained by discrimination using the device 6. The power supply device 3 supplies power Pout in an output mode according to the type of the power supply. Each relay device 6 (electrical medical device 1) is connected to the relay device 6 in a different output mode depending on the type of the relay device 6. A power supply unit 3 supplies power Pout to the connected electrical medical device 1 .

[0058] As a result, in this embodiment, unlike the general electrical medical device system described above, In this case, the electric medical device 1 and the power supply unit 3 are prevented from becoming large in size, and the output mode of the electric power Pout is As a result, it is possible to improve extensibility (ensuring a variety of output modes). As a result, in this embodiment, it is possible to improve convenience while achieving miniaturization.

[0059] In this embodiment, during the output period of the power Pout from the power supply device 3, the determination is performed. This prevents erroneous judgments caused by noise signals when the power is on (The noise signals when the power is on This makes it possible to avoid the execution of a judgment based on the bit information IB whose contents have changed due to the change in the bit information IB. This improves the discrimination accuracy of the discrimination unit 35, thereby making it possible to further improve convenience. It becomes Noh.

[0060] In this embodiment, during the period when the output of the power Pout is stopped, the discrimination information 610 (bit information I If it detects that the contents of B) have changed, the change is only detected after going through the disconnected state of relay device 6. Since the discrimination is performed based on the contents of discrimination information 610 after the discrimination, the following results are obtained: That is, only when the relay device 6 connected to the power supply device 3 is replaced, the determination after the change is Since the determination is based on the contents of the information 610, for example, noise signals other than those during power supply are not detected. This makes it possible to avoid erroneous determinations based on changes in content caused by the number of messages. As a result of improving the discrimination accuracy in 5, it is possible to further improve convenience.

[0061] <2. Modifications> Next, modified examples (modifications 1 and 2) of the above embodiment will be described. Components that are the same as those in the previous embodiment are given the same reference numerals, and descriptions thereof will be omitted as appropriate.

The electrical medical device system 5A is different from the electrical medical device system 5 in that As will be described, the determination is made using the electrical medical device 1 together with the relay device 6 .

[0063] The electrical medical device system 5A includes a power supply unit 3A and one or more relay devices 6 (FIG. 7). In this example, there are two relay devices 6b and 6d, and an electric medical device connected to each relay device 6 individually. In the example of FIG. 1, three electric medical devices 1b, 1a1, and 1a2 are provided. When performing treatment using the electrical medical device system 5A, for example, the return electrode 4 Used appropriately.

[0064] In the example of FIG. 7, similarly to the example of FIG. 1, two connections are individually connected to the relay devices 6b and 6d. Of the connecting cables C1, one selected connecting cable C1 is connected to the output terminal of the power supply unit 3A. It is connected to Tout3 (a terminal from which power Pout, etc. is output).

[0065] The control system configured by the power supply device 3A and the relay device 6 is the "power supply device" of the present disclosure. This corresponds to a specific example of a "medical device control system."

[0066] In the relay device 6d, the number of output terminals Tout62 in the relay device 6a (FIG. 1) is changed. (Changed from one to two). The two output terminals Tout62 each have a connection cable. The electric medical devices 1a1 and 1a2 are individually connected via the cable C2. Only one of the two electric medical devices 1a1 and 1a2 is connected to the relay device 6d. Thus, both of the two electrical medical devices 1a1, 1a2 are connected simultaneously.

[0067] In the power supply device 3A, the discrimination unit 35 in the power supply device 3 (FIG. 1) is replaced with a discrimination unit 35A. The other configurations are basically the same.

[0068] FIG. 8 shows a detailed configuration example of a part related to the discrimination according to the first modification (discrimination information 610A includes The following is an example of a circuit configuration that includes mechanically defined bit information IB. In the electric medical device system 5A shown in FIG. When the electric medical device 1a1 and the return electrode 4 are connected via the relay device 6d, An example of this is shown.

[0069] The relay device 6d is the relay device 6 (relay device 6a) shown in FIG. Instead of the information storage unit 61 having the discrimination information 610, an information storage unit 61A having the discrimination information 610A is used. It is equipped with:

[0070] The information storage unit 61A stores discrimination information 610 including bit information IB, similarly to the information storage unit 61. However, the information storage unit 61A has three In addition to the switches Sa, Sb, and Sc, it has two connection pins Pd and Pe. The state (on or off) of each switch Sa, Sb, Sc and each connection pin Pd, Pe The information indicating the state is bit information IB (information of each bit: “0 " or "1". The connection pin Pd corresponds to the discrimination unit 35A in the power supply device 3A. The connection is disposed between the wiring Ld connected to the ground and the wiring LG connected to the ground. The pin Pe is connected between the wire Le connected to the discrimination unit 35A in the power supply device 3A and the wire LG. are located at.

[0071] For example, as shown in FIG. 8, the connection pin Pd is connected to a wiring included in the connection cable C2. An electric medical device 1a1 can be connected via L21. The electrical medical device 1a2 can be connected via wiring included in the connection cable C2. In the example of FIG. 8, of the two connection pins Pd and Pe, the connection pin Pd has In other words, the connection pin Pd is in the ON state (distribution The connection pin Pe is set to the OFF state (open wiring). This allows the power supply VD to be connected to resistor R as shown by the dashed arrow in Figure 8. , through the wiring Ld, the connection pin Pd, the wiring L21 and the wiring LG, The current ID flows toward the ground. Meanwhile, the current flows toward the wiring Le and the connection pin Pe. In each of the switches, a current ID of a predetermined value or more does not flow. Even when Sb, Sc or each connection pin Pd, Pe is in the OFF state, it can be determined from the power supply VD. A minute current less than a predetermined value flows through the separate portion 35 .

[0072] The determination unit 35A determines bit information IB (in FIG. 8) based on the voltage state on each of the wirings La to Le. In this example, the contents of the 5-bit bit information IB are determined. That is, the switches Sa and Sb , Sc or the connection pins Pd, Pe are set to the ON state, the wirings La to L Since the voltage state on the bus e becomes the ground level ("L" level), the discrimination unit 35A The bit information IB of the switch is judged as "0". When the pins Pd and Pe are set to the off state, the voltage state on the lines La to Le is Since the power supply VD level ("H" level) is reached, the discrimination unit 35A determines the bit information I B="1". Therefore, in the example of FIG. 8, In order, the 5-bit bit information IB is determined as "11001". The order of bits is not limited to the example shown in FIG. 8 and can be set arbitrarily. The contents of the discrimination information 610A include the type of the electric medical device 1 connected to the relay device 6 (relay In this way, the discrimination unit 35A determines whether the relay device The electrical medical device 1 is further used in conjunction with 6 to perform the discrimination.

[0073] FIG. 9 shows an example of a truth table Tb' used in the determination according to the first modification. Specifically, the truth table Tb' is configured as follows according to the contents of the discrimination information 610A (bit information IB): 1 shows an example of an output mode of power Pout from a power supply device 3A.

[0074] The power supply device 3A, together with the relay device 6, further performs discrimination using the electric medical device 1 (discrimination unit 3 The electrical medical device connected to the relay device 6 obtained by the determination in 5A. The power supply device 3A outputs the electric power Pout in an output mode corresponding to the type of the power supply device 3A. Each relay device 6 (electrical medical device 1) is connected to the relay device 6 in a different output mode depending on the type of the relay device 6. It outputs power Pout to the connected electrical medical device 1.

[0075] The discrimination unit 35A, for example, as shown in FIG. 9, outputs the discrimination information 610A (bit information Based on the contents of IB), the discrimination unit 35A discriminates as follows. The connection status (connected or unconnected) of relay device 6 to the The connection status of the medical device 1 and the type and The type and number of the electric medical devices 1 are determined. The output format, operating mode and maximum output power are included.

[0076] According to the contents of the discrimination information 610A (contents of each bit in the 5-bit bit information IB), A specific example of the output mode of the power Pout is as follows, as shown in the truth table Tb' of FIG. In addition, in FIG. 9, whether or not the power Pout can be output in each state is also shown. This is shown.

[0077] 5th bit information = "0": Connection status of relay device 6 (Pout output possible) 5th bit information = "1": Relay device 6 is not connected (Pout output is not possible)

[0078] · 4th bit, 3rd bit information = "00": Coagulation mode (unipolar type) · 4th bit, 3rd bit information = "01": Coagulation mode (bipolar type) 4th bit, 3rd bit information = "10": Cutting mode (unipolar type) 4th bit, 3rd bit information = "11": Cutting mode (bipolar type)

[0079] 2nd bit, 1st bit information = "00": 2 electrical medical devices 1a1, 1a2 Connection Status - 2nd bit, 1st bit information = "01": Connection status of 1 (electrical medical device 1a1) Mode (50[W] mode) 2nd bit, 1st bit information = "10": Connection status of 1 (electrical medical device 1a2) Mode (100[W] mode) - 2nd bit, 1st bit information = "11": Both are not connected (Pout output is not possible)

[0080] In addition, when it is determined that both of the two electric medical devices 1a1 and 1a2 are in a connected state, For example, if two simultaneous connections are not permitted, the power Pout cannot be output. It may be set as follows.

[0081] Here, in the first modification, as in the embodiment, the discrimination unit 35A receives the power supply device 3A from During the output period of the power Pout, the determination unit 35A does not perform the determination. During the period when the output of the power Pout from the device 3A is stopped, the discrimination information 610A (bit information IB ) is detected to have changed, the relay device 6 or the electrical medical device 1 is disconnected. After the state has changed, discrimination is performed based on the contents of discrimination information 610A after the change.

[0082] (Action and effect) In this manner, in the first modification, the discrimination unit 35A determines whether the relay device 6 and the electric medical device Since the determination is performed by further using the device 1, the result is as follows. In Example 1, unlike the embodiment, the number of relay devices 6 is limited to one, and multiple types of power supplies are connected. This will enable the output of power Pout according to the discrimination. The variation in the form can be improved with a simpler configuration. As a result, in the first modification, it is possible to further improve convenience compared to the embodiment. become.

[0083] In the first modification, similarly to the embodiment, during the period when the output of the power Pout is stopped, the discrimination information 61 When it detects a change in the contents of 0A (bit information IB), relay device 6 or electrical Only after the medical device 1 has passed through a non-connected state, a determination based on the changed content of the determination information 610A is made. Since the relay device 6 or the electrical medical device Only when the device 1 is replaced, discrimination based on the changed contents of the discrimination information 610A is performed. Therefore, for example, misjudgment due to changes in content caused by noise signals other than those during power-on may occur. As a result, in the first modification, as in the embodiment, the determination As a result of improving the discrimination accuracy in the separate part 35A, it is possible to further improve convenience. .

In other words, the electrical medical device system 5B includes a power supply 3B , a relay device 6B, and an electric medical device 1a.

[0085] The control system configured by the power supply device 3B and the relay device 6B is the " This corresponds to one specific example of an "electrical medical device control system."

The electrical medical device system 5B is the same as the electrical medical device system 5A of the first modification (FIG. 8). In the above, a power supply unit 3B is provided instead of the power supply unit 3A, and a relay device 6 (relay device 6d), a relay device 6B is provided, and the other configurations are the same.

[0087] In the power supply unit 3B, the discrimination unit in the power supply unit 3 (FIG. 2) or the power supply unit 3A (FIG. 8) 35 or discrimination unit 35A is omitted (not provided), and the other configurations are the same. There are.

[0089] In this manner, in the second modification, the discrimination unit 35 or the discrimination unit 35A determines whether the power supply unit 3 A, it is arranged in relay device 6B.

[0090] In the second modification, the same operation as in the first embodiment is basically performed. It is possible to obtain a similar effect.
