Description

  The present invention relates to a wireless electronic endoscope system that exchanges image data obtained by imaging an inside of a subject through wireless communication between the electronic endoscope and a processor device.

  Conventionally, medical diagnosis using an electronic endoscope has been actively performed in the medical field. A solid-state imaging device such as a CCD and an illuminating unit that illuminates the inside of the body cavity are incorporated at the distal end of the insertion part that is inserted into the body cavity of the electronic endoscope. An image in the body cavity can be observed on the monitor by performing various signal processing on the imaging signal output from the CCD by the processor device.

  Usually, the electronic endoscope and the processor device are connected by a signal cable. Recently, a so-called wireless electronic endoscope system in which the signal cable is removed has been devised. In this system, a modulation unit that modulates a signal into radio waves, a transmission unit that transmits radio waves to an electronic endoscope, a reception unit that receives radio waves, and a demodulation unit that demodulates radio waves into original signals Provided so that signals can be exchanged between the electronic endoscope and the processor device by radio waves.

  In the wireless electronic endoscope system, when the electronic endoscope is used, the operation restriction by the signal cable is eliminated, and the operability is improved. In addition, in a conventional electronic endoscope system using a signal cable, it is essential to maintain a dielectric breakdown voltage of about 4 kV between a patient circuit on the electronic endoscope side and a secondary circuit on the processor device side. In the wireless electronic endoscope system, since there is no electrical connection by a signal cable between the electronic endoscope and the processor device, a configuration for maintaining a high withstand voltage as described above becomes unnecessary.

  Incidentally, a plurality of electronic endoscope systems are actually installed in a dedicated treatment room in a hospital. In order to save equipment costs, a plurality of types of electronic endoscopes having different uses and performances are often handled by a single processor device. For this reason, it is necessary to individually identify and manage a plurality of types of electronic endoscopes. In particular, in the case of a wireless electronic endoscope system, in order to prevent interference between electronic endoscopes, it is essential to manage the frequency of radio waves used for each electronic endoscope.

  Conventionally, management of such setting information has been performed manually by an operator entering it into a computer. However, manual input is cumbersome and there is a risk that incorrect setting information may be input. . In view of such a background, various measures have been taken to achieve the strict information management by omitting the trouble of inputting the setting information (see Patent Documents 1 to 3).

  The technique described in Patent Document 1 is based on a transponder (non-contact ID using wireless communication) that stores information such as the number of times an electronic endoscope is cleaned and a history of use of a cable that connects the electronic endoscope and the processor device. Information is read by a reader attached near the connector and placed near the processor unit.

  Patent Document 2 discloses an endoscope system in which an RFID terminal that reads information of an RFID tag embedded in an electronic endoscope is provided on an upper side of a cart on which an electronic endoscope or a processor device is placed. Has been.

In Patent Document 3, in a wireless electronic endoscope system, a barcode indicating information on the frequency of a radio wave to be used is provided in an operation unit of the electronic endoscope, and the barcode information is obtained by a barcode reader connected to a processor device. It is described that the reception frequency of the processor device is set by reading.

  A timing generator (hereinafter abbreviated as TG) 72 is connected to the CPU 70. The TG 72 is connected to a CCD 73, an analog front end (hereinafter abbreviated as AFE) 74, and a parallel / serial conversion unit (hereinafter abbreviated as P / S) 75, and transmits timing signals (clock pulses) to these units. . The CCD 73, AFE 74, and P / S 75 operate based on the timing signal transmitted from the TG 72.

  The CCD 73 captures image light in the body cavity that is incident through the observation window 76 provided in the distal end portion 30 and the objective optical system 77. The CCD 73 is composed of, for example, an interline CCD, and a bare chip having an imaging surface on which a plurality of pixels are arranged on the surface is used.

  When image light incident through the observation window 76 and the objective optical system 77 is imaged on the imaging surface of the CCD 73, an imaging signal corresponding to this is output from each pixel of the CCD 73. Under the control of the CPU 70, the AFE 74 performs correlated double sampling, amplification, and A / D conversion on the imaging signal input from the CCD 73, and converts the imaging signal into digital image data.

  In FIG. 6, the CPU 90 controls the overall operation of the processor device 12. Connected to the CPU 90 is a ROM 91 in which various programs and data for controlling the operation of the processor device 12 are stored. The CPU 90 reads necessary programs and data from the ROM 91 and controls the operation of the processor device 12. In addition, the CPU 90 operates each unit of the processor device 12 in response to an operation input signal from the keyboard 14.

  The antenna 92 receives the radio waves 19 and 20 from the electronic endoscopes 10 and 11. The receiving unit 93 converts the radio waves 19 and 20 received by the antenna 92 into an RF signal and amplifies it with an appropriate amplification factor. The reception unit 93 is provided with a frequency switching circuit 94 that switches the reception frequency to the transmission frequency of the radio waves 19 and 20 according to the electronic endoscopes 10 and 11 to be used.

  The demodulator 95 performs, for example, digital quadrature detection on the RF signal obtained by converting the radio waves 19 and 20, and demodulates the RF signal into image data before being modulated by the electronic endoscopes 10 and 11. Under the control of the CPU 90, the image processing unit 96 performs various image processing such as γ correction and white balance correction on the image data demodulated by the demodulating unit 95, and obtains an endoscopic image, patient personal information, Display control such as addition of character information such as inspection date to the template. The image data subjected to various image processing and display control by the image processing unit 96 is displayed on the monitor 13 as an endoscopic image.

  The setting information of the tag 38 read by the reader 22 is input to a built-in RAM (not shown) of the CPU 90. The CPU 90 reads the setting information of the electronic endoscope selected to be used with the keyboard 14 among the electronic endoscopes 10 and 11 from the built-in RAM, and controls the operation of each unit based on the read setting information. Specifically, the reception frequency of the frequency switching circuit 94 is switched to the radio wave transmission frequency of the electronic endoscope selected for use. The contents of the image processing and display control performed by the image processing unit 96 according to the model number of the electronic endoscope selected to be used, the specifications of the CCD, or the data of the template when displaying the endoscope image, etc. change.

  When observing the inside of a patient's body cavity with the wireless electronic endoscope system 2 configured as described above, the electronic endoscopes 10 and 11 are operated by turning on the power of the processor device 12 and operating the keyboard 14. Among them, the electronic endoscope to be used (here, for convenience of explanation, the electronic endoscope 10 is selected) is selected and its power is turned on. Then, the electronic endoscope 10 is removed from the hanger 21, the insertion portion 17 is inserted into the body cavity, and the endoscope image obtained by the CCD 73 is observed on the monitor 13 while illuminating the inside of the body cavity with the LED 82.

  When the power of the processor device 12 is turned on, the reader 22 is driven and the setting information of the tags 38 of the electronic endoscopes 10 and 11 is read. Setting information read by the reader 22 is input to the CPU 90. Further, the power transmission circuit 23 on the side where the electronic endoscope not selected for use (in this case, the electronic endoscope 11) is suspended is driven, and power is supplied to the power receiving circuit 39 of the electronic endoscope 11. The Thereby, the battery 84 of the electronic endoscope 11 is charged.

  The image light in the body cavity that has entered through the observation window 76 and the objective optical system 77 is imaged on the imaging surface of the CCD 73, whereby an imaging signal is output from the CCD 73. The imaging signal output from the CCD 73 is subjected to correlated double sampling, amplification, and A / D conversion by the AFE 74, and is converted into digital image data.

  The digital image data output from the AFE 74 is converted into serial data by P / S75. The serial data output from the P / S 75 is subjected to digital quadrature modulation by the modulation unit 78 and becomes an RF signal. The RF signal is emitted as a radio wave 19 from the antenna 80 via the transmission unit 79.

  On the other hand, in the processor device 12, the reception frequency of the frequency switching circuit 94 is switched to the frequency of the radio wave 19 by the CPU 90 based on the setting information read from the tag 38 of the electronic endoscope 10. When the radio wave 19 is received by the antenna 92, the radio wave 19 is converted into an RF signal and amplified by the receiving unit 93. Then, the demodulation unit 95 performs digital quadrature detection on the RF signal from the reception unit 93, and the RF signal is demodulated into image data before being modulated by the modulation unit 78.

  The image data demodulated by the demodulator 95 is subjected to image processing and display control according to the setting information of the tag 38 of the electronic endoscope 10 by the image processor 96 under the control of the CPU 90, and Displayed as an endoscopic image.

  When the electronic endoscope 10 is used and the keyboard 14 is operated and the electronic endoscope 11 is selected as the electronic endoscope to be used, it is read from the tag 38 of the electronic endoscope 11. Based on the setting information, the reception frequency of the frequency switching circuit 94 is switched from the frequency of the radio wave 19 to the frequency of the radio wave 20. Further, image processing and display control according to the setting information of the electronic endoscope 11 are performed, and the display on the monitor 13 is changed for the electronic endoscope 11.

  As described above, since the reader 22 is provided on the hanger 21 on which the electronic endoscopes 10 and 11 are suspended, the setting information can be read without the operator consciously performing the operation of reading the setting information. Moreover, since the tag 38 is provided in the part of the hanger 21 that faces the reader 22 when the electronic endoscopes 10 and 11 are suspended, reading defects can be prevented.

  Since the reader 22 and the tag 38 are used for exchanging the setting information, it is possible to transmit a large amount of information at a time compared to a barcode or the like. Further, since the passive method is adopted for the tag 38, it is not necessary to secure the power supplied to the tag 38 on the electronic endoscope 10, 11 side, and the power consumption of the electronic endoscope 10, 11 can be suppressed.

  Since the battery 84 is charged by the power transmission circuit 23 and the power reception circuit 39, it is not necessary to prepare a separate charger, and work such as removing the battery 84 from the connector 85 and setting it in the charger is omitted. Moreover, the waiting time when the electronic endoscope is not used is not wasted.

  Since the power transmission circuit 23 and the power reception circuit 39 are configured to charge the battery 84 in a non-contact manner, compared to a configuration in which a contact between the power transmission circuit and the power reception circuit is provided and charging is performed in a contact manner, contact corrosion and contact This is advantageous because it can prevent defects and short-circuiting caused by water droplets.

  Since radio frequency information is transmitted and received as setting information, and the frequency is switched by the frequency switching circuit 94 based on this information, interference between electronic endoscopes can be reliably prevented.

  In the above embodiment, the electronic endoscopes 10 and 11 having predetermined frequencies of the radio waves 19 and 20 are used, and the frequency switching circuit 94 of the processor device 12 matches the radio waves of the electronic endoscope selected for use. Although the aspect which switches a receiving frequency is illustrated, as the example shown in FIG.7 and FIG.8, an electronic endoscope and a processor apparatus have a several frequency channel, and the structure which can transmit / receive the electromagnetic wave of several frequencies When using the system, the electronic endoscope inquires the processor device about a channel with an unused frequency that is not currently used, and receives information on the available channel with the electronic endoscope as setting information. You may transmit and receive with an electromagnetic wave.

  7, the electronic endoscope 100 includes an electronic internal circuit shown in FIG. 5 except that a data separation circuit 101 is provided between the power receiving circuit 39 and the battery 84, and a frequency switching circuit 102 is provided in the modulation unit 78. The configuration is the same as that of the endoscope 10. 8, the processor device 110 is the same as the configuration of the processor device 12 shown in FIG. 6 except that a data superimposing circuit 111 is provided between the power transmission circuit 23 and the CPU 90. In this case, as in the above embodiment, the following description will be given on the assumption that the processor device 110 handles a plurality of electronic endoscopes having the same configuration as the electronic endoscope 100 and having different uses and performances.

  The data superimposing circuit 111 is free of AC voltage applied to the power transmission coil 60 of the power transmission circuit 23 corresponding to the electronic endoscope selected for use on the keyboard 14 (here, for convenience of explanation, the electronic endoscope 100). Superimpose channel information. The data separation circuit 101 separates the signal received by the power receiving coil 61 of the power receiving circuit 39 into a power component and a data component superimposed by the data superimposing circuit 111. Then, the power component is supplied to the battery 84, the data component is demodulated to the original empty channel information, and this is output to the CPU 70.

  The CPU 70 switches the frequency of the frequency switching circuit 102 based on the information on the empty channel. Even when the use of an electronic endoscope other than the electronic endoscope 100 is selected, information on empty channels is exchanged in the same manner as described above, and the transmission frequency of the electronic endoscope is switched. When all the channels are occupied, for example, a signal indicating that the channels cannot be used is transmitted instead of the information on the empty channels. In this case, the setting information exchanged between the reader 22 and the tag 38 is information excluding frequency information in the above embodiment. Thus, if the power transmission circuit 23 and the power reception circuit 39 are also used as means for wirelessly communicating the setting information, these can be utilized more effectively.

  In the above embodiment, the electronic endoscope to be used is manually turned on. However, when the electronic endoscope is hung on the hanger 21, the electronic endoscope is automatically turned off and removed from the hanger 21. A configuration may be adopted in which the power is automatically turned on.

  Note that the reader 22 and the tag 38, the power transmission circuit 23, and the power reception circuit 39 have been described as examples of means for wirelessly communicating the setting information, but other wireless communication means such as infrared communication may be used. The present invention is not particularly limited to the configuration of wireless communication. Further, the charging configuration may not be contactless, and a contact-type charger may be used in consideration of the problem described in paragraph [0050]. Furthermore, the setting information and control such as frequency switching associated with the setting information described in the above embodiment are merely examples, and can be changed as appropriate without departing from the gist of the present invention.
