Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device connected to a plurality of medical devices and controlling the plurality of medical devices. 2. Description of the Related Art In recent years, for example, endoscope apparatuses have been widely used in the medical and industrial fields. Particularly in the medical field, a system configuration in which other endoscope peripheral devices such as an electrosurgical unit in addition to the endoscope device are connected to perform endoscopic surgery or endoscopic diagnosis is widely adopted. ing. [0003] In addition, the applicable range of endoscopic surgery and endoscopic diagnosis is widened, and a system may be configured by selectively changing medical devices to be connected in accordance with the applicable range. In the endoscopic surgery, a pneumoperitoneum device for insufflating the abdominal cavity is used, but in a lower endoscopic operation using a nasal scope, the pneumoperitoneum device is unnecessary and is not used. In such a system, a plurality of medical devices connected to a system controller as a control device are centrally controlled, and the system controller sets control items and operation modes of the medical devices to be controlled by a connected display monitor or the like. A graphic user interface (hereinafter referred to as G) for displaying a screen and operating the setting screen with a pointer or the like.
The operation is facilitated by adopting UI). Further, such a system controller stores a control program of a medical device to be connected and image data of a setting screen in a nonvolatile memory or a recording medium in the control device, and stores the stored control program in the control device. In some cases, the functions are realized by being executed by a CPU, and further, by communicating with an external computer or the like and rewriting various data such as a control program, a function is added or a corresponding device is added. [0006] However, the conventional control device stores in advance all control programs and operation screen data of devices that can be connected and controlled, and according to the adaptation range and the procedure. The device is selectively set on the device selection screen so that the device to be used selectively can be controlled, and the operation screen corresponding to the device is selectively read out based on the selected and set information, for example, to perform treatment in the abdominal cavity. In the procedure, we want to constantly monitor the status of the insufflation device that insufflates the abdominal cavity in order to secure the operative field. Possible operation screen data is required, but in procedures of other parts that do not use the insufflation device, only the operation setting of the electric knife and the operation screen that can be set between the electric knife and the ultrasonic knife, etc. Many maneuvers It is necessary to store the data of the operation screen, and in particular, since the image data of the operation screen and the like has a large data amount, it is necessary to adopt a large storage capacity. Further, in order to cope with rewriting of the control program and the data of the operation screen, it is necessary to provide a margin capacity for an additional device. for that reason,
Adopting a memory having a large storage capacity in advance has a disadvantage that the cost of the control device increases. [0008] The present invention has been made in view of the above circumstances, and provides a control device capable of configuring a menu screen according to a connected device even when the connected medical device is changed. It is an object. A control device according to the present invention is connected to a plurality of medical devices, and in the control device for controlling the plurality of medical devices, the control device determines which medical device is connected to the control device.

It is used by connecting to the control device 8 with a communication cable. Next, the operation of the thus configured surgical system 1 will be described. As shown in FIG. 8, at the time of startup, the control device 8 transmits a device name code request for each channel to determine the device connected to each channel of the USB interface 701 (step S1). ). Each device connected to the USB interface 701 reads the device name code stored in the memory of each device and reads the device name code stored in the memory of each device. The device name code. Based on the device name code of each device received by the USB interface 701, the CPU 702
Performs a process of determining each connected device (step S2). Next, the CPU 702 determines the USB interface 70 based on the determination result determined in the processing of S2.
The priority for each channel is set (step S3). For example, in the above-described laparoscopic endoscopic operation, it is necessary to monitor the pressure in the abdominal cavity during the operation, so the channel to which the insufflation device 7 is connected has the highest priority. Electric scalpel device 5, ultrasonic scalpel device 6, CCU
3. The light source device 4 is set in this order, and in an endoscopic operation based on nasal passage, the electric scalpel device 5, the CCU 3, and the light source device 4 are set in this order. The CPU 702 performs a process of instructing each device to transmit the icon data and the data for the main operation screen stored in the memory of each device (step S).
4). The CPU 702 sets the display position of the icon data and the data for the main operation screen transmitted from each device based on the determination result determined in the process of S2 (step S5), and sets the display position. Display processing of each icon data to which the graphic has been transmitted and the data for the main operation drawing (step S)
6). For example, when an operation screen as shown in FIG. 9 is displayed, an area 80 for arranging icons in advance is displayed.
1, the icon data 8 is stored in this area 801.
The display positions are set so that 02a, 802b, 802c, 802d, and 802e are arranged at predetermined intervals. An area 803 for arranging operation items for the main operation drawing is provided, and the display position is set so that the main operation screen data 804b, 804c, 802d, 804e are arranged at predetermined intervals. . Further, when an insufflation device is connected,
The display position of the monitoring item data 804a is set in the area 803. The display data of the numerical value in the area 803 is displayed using the font data inside the control device 8 because the numerical value itself is exchanged with each device by communication. Next, the operation when each icon is operated while the operation screen as shown in FIG. 9 is displayed will be described with reference to FIG. In FIG. 10, an input is awaited in the judgment processing of step S7, and when an operation input on the touch panel is input, the flow shifts to S8. In step S8, the operation content is determined based on the operated screen position and the icon display position set in step S5. For example, when the icon data 802a is operated, since the icon data of the insufflation device 7 is set, it is determined that the operation screen of the insufflation device 7 is read. In step S9, it is determined whether or not the operation contents determined in step S8 require updating of the icon data and items of the operation screen.
Move to 10. In step S10, a request for transmission of operation screen data corresponding to the operation content determined in step S8 is made to the connected device. In step S11, the graphic controller 704 performs display processing based on the operation screen data transmitted in response to the request in step S10. For example, the operation screen data 810 for the insufflation device 7 as shown in FIG.
5 and the data is displayed in the area 803. At this time, the icon data 803a
The data of different colors are also transmitted together and changed. If it is determined in step S9 that the icon data and the item do not need to be updated, for example, if the up icon on the operation screen is operated, the graphic controller 704 performs only the display processing. The icon data and item data of the present embodiment are image data. Therefore, if this image data is changed for each destination, it is possible to support various languages. By the way, conventionally, a character image signal is superimposed on an image signal output from the CCU 3 to display a character, or code information is superimposed on an image signal to cope with a code superimposed on the receiver side. Character display with character data. In the present embodiment, the image data compressed by the DV compression circuit 204 is output to the IEEE 1394 interface 208, and the CPU 205 determines, for example, the data to be displayed such as set values and the like for each language. IEEE139
4 interface 208. IEEE139
The four interface 208 transmits image data, data to be displayed, and a plurality of codes corresponding to each national language in a sequence. In the observation monitor 9, an IEEE 1 (not shown)
The 394 interface separates the image data received in sequence and the data to be displayed from the multiple codes for each national language, and selects and sets one of the separated multiple codes for each national language for the data to be displayed. I do. For example, if a plurality of codes are English, German, and Japanese, if the monitor setting is the first, English will be displayed.
The second setting will display German. Further, since connection is made by the IEEE 1394 interface, when there are a plurality of connection ports of each device, chain connection and address control allow superimposed data and codes to be received only by the specified device, and control Corresponding control data can be generated in association with the control setting from the device 8 and transmitted to the observation monitor 9 or a printer (not shown). As described above, according to the present invention, there is an effect that even if the connected medical device is changed, a menu screen corresponding to the connected device can be configured.
