Description

内視鏡システムEndoscope system
　本発明は、内視鏡システム、特に、内視鏡および当該内視鏡を接続可能とするプロセッサを備える内視鏡システムに関する。 The present invention relates to an endoscope system, particularly an endoscope system including an endoscope and a processor capable of connecting the endoscope.
　被検体の内部の被写体を撮像する内視鏡、及び、内視鏡において撮像された被写体の観察画像に対し所定の画像処理を施して出力するビデオプロセッサ等を具備する内視鏡システムが、医療分野及び工業分野等において広く用いられている。 An endoscope system including an endoscope that captures a subject inside a subject and a video processor that performs predetermined image processing on the observation image of the subject captured by the endoscope and outputs the image is medical treatment. Widely used in fields and industrial fields.
　このような内視鏡システムにおいては、患者の連続検査、または、術中に違う種類の内視鏡を交換する等、１台のビデオプロセッサに対して複数種の内視鏡が接続され得る。このような状況において、ビデオプロセッサに接続された内視鏡を、いわゆる活線抜去すると、例えば、内視鏡またはビデオプロセッサにおける回路上のコンデンサに電荷がチャージされたままになる場合がある。コンデンサに電荷が蓄積された状態において（電荷の放電が完了していない状態で）当該内視鏡を再びビデオプロセッサに接続すると、当該コンデンサにチャージされた電荷によって当該回路上に接続されたＩＣ等の電気部品にダメージを与える虞がある。 In such an endoscope system, multiple types of endoscopes can be connected to one video processor, such as continuous examination of patients or replacement of different types of endoscopes during surgery. In such a situation, if the endoscope connected to the video processor is so-called live wire removed, for example, the capacitor on the circuit of the endoscope or the video processor may remain charged. When the endoscope is connected to the video processor again when the electric charge is accumulated in the capacitor (when the electric charge is not completely discharged), the IC or the like connected on the circuit by the electric charge charged in the capacitor is used. There is a risk of damaging the electrical components of.
　この状況に対処するために、例えば、違う種類の内視鏡交換が必要となった場合、ビデオプロセッサの電源をオフした後、内視鏡システムの立下げ処理（放電処理を含む）を行い、この立ち下げ処理が完了した後に内視鏡を抜去することが考えられる。そして、再度ビデオプロセッサの電源をオンし、交換予定の内視鏡がビデオプロセッサに接続された後、内視鏡システムの立上げ処理を行うこととしている。 To deal with this situation, for example, if a different type of endoscope needs to be replaced, the video processor is turned off, and then the endoscope system is shut down (including discharge). It is conceivable to remove the endoscope after this down-down process is completed. Then, the power of the video processor is turned on again, the endoscope to be replaced is connected to the video processor, and then the endoscope system is started up.
　一方、日本国特開２００９-１８９５２８公報においては、内視鏡の抜去が開始されたことを検出すると、内視鏡における撮像素子への駆動信号および電源供給を停止する技術が示されている。 On the other hand, Japanese Patent Application Laid-Open No. 2009-189528 describes a technique for stopping the drive signal and power supply to the image sensor in the endoscope when it is detected that the removal of the endoscope has started.
　しかしながら、日本国特開２００９-１８９５２８公報に記載の技術においては、放電処理を含む内視鏡システムの立ち下げシーケンスが完了しているかどうかは不明であり、すなわち、抜去した内視鏡には依然としてコンデンサに電荷が蓄積されたままであることも考えらえれ、この状態で再びビデオプロセッサに再接続すると、当該回路上に接続されたＩＣ等の電気部品にダメージを与える虞がある。 However, in the technique described in Japanese Patent Application Laid-Open No. 2009-189528, it is unclear whether the start-up sequence of the endoscope system including the discharge treatment is completed, that is, the removed endoscope still has. It is conceivable that the electric charge is still accumulated in the capacitor, and if it is reconnected to the video processor in this state, there is a risk of damaging the electric components such as the IC connected on the circuit.
　また、内視鏡の挿抜の度に、ビデオプロセッサの電源のオフ動作およびオン動作を要する従来の内視鏡システムでは、このオフ動作とオン動作の際における内視鏡システムの立下げと立上げの時間分ほど、内視鏡交換の時間ロスを生じていた。特に、内視鏡の交換を頻繁に要する場合、実際に内視鏡を使用することが可能となるまでのタイムラグは、ユーザの作業性を著しく下げていた。 Further, in the conventional endoscope system that requires the power of the video processor to be turned off and on each time the endoscope is inserted or removed, the endoscope system is started up and down during the off and on operations. There was a time loss for replacing the endoscope for about the same amount of time. In particular, when the endoscope needs to be replaced frequently, the time lag until the endoscope can be actually used has significantly reduced the workability of the user.
　本発明は上述した事情に鑑みてなされたものであり、内視鏡をビデオプロセッサから挿抜する際に、ビデオプロセッサの電源のオフ・オン動作を要することなく内視鏡の活線挿抜を行うことができ、内視鏡の交換を容易にすることができる内視鏡システムを提供する。 The present invention has been made in view of the above circumstances, and when the endoscope is inserted and removed from the video processor, the live line of the endoscope is inserted and removed without requiring the power off / on operation of the video processor. To provide an endoscope system capable of facilitating the replacement of an endoscope.

　＜放電回路について＞
　ここで、上記放電回路２５および上述した映像信号ラインにおけるコンデンサに蓄積される電荷について、図３、図４を参照して説明する。 <About the discharge circuit>
Here, the electric charges accumulated in the discharge circuit 25 and the capacitor in the video signal line described above will be described with reference to FIGS. 3 and 4.
　図３は、従来の内視鏡システムにおいて、内視鏡がビデオプロセッサに接続された際における、映像信号ライン上に配置されたコンデンサの従来の周辺回路を示した回路図であり、図４は、第１の実施形態の内視鏡システムにおいて、内視鏡がビデオプロセッサに接続された際における、映像信号ライン上に配置されたコンデンサおよび放電抵抗を示した回路図である。 FIG. 3 is a circuit diagram showing a conventional peripheral circuit of a capacitor arranged on a video signal line when an endoscope is connected to a video processor in a conventional endoscope system, and FIG. 4 is a circuit diagram showing a conventional peripheral circuit of a capacitor arranged on a video signal line. , Is a circuit diagram showing a capacitor and a discharge resistance arranged on a video signal line when the endoscope is connected to a video processor in the endoscope system of the first embodiment.
　図３に示す従来の内視鏡システムにおいては、例えば、内視鏡およびビデオプロセッサそれぞれの画像処理用ＩＣ（例えば、ＦＰＧＡ等）に接続された映像信号ラインには、所定のコンデンサが直列に配設されている。このような構成を成す内視鏡がビデオプロセッサに接続された状態において映像信号ラインが活線状態になると、これらコンデンサには所定の電荷がチャージされることになる。 In the conventional endoscope system shown in FIG. 3, for example, a predetermined capacitor is arranged in series in a video signal line connected to an image processing IC (for example, FPGA) of each of the endoscope and the video processor. It is installed. When the video signal line becomes live while the endoscope having such a configuration is connected to the video processor, these capacitors are charged with a predetermined charge.
　そして、この状態において内視鏡がビデオプロセッサから活線抜去された場合を想定する。従来の内視鏡およびビデオプロセッサにおいては、図３に示すように、これらコンデンサにチャージされた電荷が放電される経路がないため、活線抜去された後もコンデンサには所定の電荷がチャージされたままの状態となる。 Then, assume that the endoscope is live-lined from the video processor in this state. In conventional endoscopes and video processors, as shown in FIG. 3, since there is no path for discharging the charges charged in these capacitors, the capacitors are charged with a predetermined charge even after the live wire is removed. It will be in the same state.
　コンデンサに所定の電荷がチャージされたままの状態において、内視鏡を再びビデオプロセッサに再接続すると、コンデンサにチャージされた電荷によってＩＣ等の電気部品にダメージを与える挙動を示すことがある。 If the endoscope is reconnected to the video processor while the capacitor is still charged with a predetermined charge, the charge charged in the capacitor may cause damage to electrical components such as ICs.
　本第１の実施形態の内視鏡システムは、図４に示すように、内視鏡２のスコープ基板におけるＣＰＵ２１と、ビデオプロセッサ３におけるＣＰＵ３１との間における映像信号ライン２０Ｂ，３０Ｂにおいて、内視鏡２側の映像信号ライン２０Ｂにプルダウン抵抗により構成される放電回路２５を接続する。具体的には、放電回路２５は、映像信号ライン２０Ｂ上に直列に配設されたコンデンサ２０Ｃの出力端子とグランド間に接続されたプルダウン抵抗として構成される。 As shown in FIG. 4, the endoscope system of the first embodiment is used for endoscopy in the video signal lines 20B and 30B between the CPU 21 in the scope substrate of the endoscope 2 and the CPU 31 in the video processor 3. A discharge circuit 25 composed of a pull-down resistor is connected to the video signal line 20B on the mirror 2 side. Specifically, the discharge circuit 25 is configured as a pull-down resistor connected between the output terminal of the capacitor 20C arranged in series on the video signal line 20B and the ground.
　これらプルダウン抵抗は、上述したように、コンデンサの出力端子とグランド間に接続されたプルダウン抵抗であるが、本実施形態においては、比較的大きな容量であって、かつ、配置する映像信号ラインの動作に影響を与えない抵抗値、例えば１０ｋΩの抵抗値を有する抵抗により構成される。 As described above, these pull-down resistors are pull-down resistors connected between the output terminal of the capacitor and the ground, but in the present embodiment, they have a relatively large capacitance and the operation of the video signal line to be arranged. It is composed of a resistor having a resistance value that does not affect, for example, a resistance value of 10 kΩ.
　この放電抵抗により、内視鏡２の電源がオフされた際、当該抵抗により電流が流れる経路が構成されることにより、コンデンサにチャージされた電荷が適宜放電されるようになっている。当該電荷が放電された後は、内視鏡２がビデオプロセッサ３に対して再接続されたとしても、ＩＣ等の電気部品にダメージを与えることはない。 Due to this discharge resistance, when the power of the endoscope 2 is turned off, the current flow path is configured by the resistance, so that the electric charge charged in the capacitor is appropriately discharged. After the electric charge is discharged, even if the endoscope 2 is reconnected to the video processor 3, the electric components such as the IC are not damaged.
　＜第１の実施形態の作用＞
　次に、上述した如き構成をなす本第１の実施形態の内視鏡システム１において、ビデオプロセッサ３から内視鏡２を抜去する仕方を図２、図５および図６を参照して説明する。 <Operation of the first embodiment>
Next, in the endoscope system 1 of the first embodiment having the above-described configuration, a method of removing the endoscope 2 from the video processor 3 will be described with reference to FIGS. 2, 5 and 6. ..
　ビデオプロセッサ３に内視鏡２が接続され（検知部３３の検知結果に基づいて接続が判別される）、かつ、いずれも電源がオン状態にあるときにおいて、ビデオプロセッサ３から内視鏡２を抜去する際、ユーザはまず、図５に示すようにタッチパネルである表示部３６における内視鏡取り外しボタン３７を押下する。 When the endoscope 2 is connected to the video processor 3 (the connection is determined based on the detection result of the detection unit 33) and the power is on, the endoscope 2 is connected from the video processor 3. At the time of removal, the user first presses the endoscope removal button 37 on the display unit 36 which is a touch panel as shown in FIG.
　ＣＰＵ３１が、当該内視鏡取り外しボタン３７の押下を検出すると、一旦システム制御を待機状態にした後、スコープ制御回路３２に対してスコープ立ち下げの処理を指示する（図２参照）。スコープ制御回路３２は、このＣＰＵ３１からのスコープ立ち下げ指示を受けると、内視鏡２に対する電源供給をオフするようスコープ立ち下げ制御を実行する（図５、図２参照）。 When the CPU 31 detects that the endoscope removal button 37 is pressed, the system control is once put into a standby state, and then the scope control circuit 32 is instructed to process the scope down (see FIG. 2). Upon receiving the scope lowering instruction from the CPU 31, the scope control circuit 32 executes the scope lowering control so as to turn off the power supply to the endoscope 2 (see FIGS. 5 and 2).
　内視鏡２においては、電源供給がオフするシーケンスにおいて、映像信号ライン２０Ｂにおけるコンデンサに蓄積された電荷が放電回路２５により所定の時定数を伴って徐々に放電される。なお、本実施形態においては、上述したシステム制御の待機時間を当該放電の時間に対応して設定している。すなわち、内視鏡２の機種ごとに僅かに異なる放電時間に対応して設定されている。 In the endoscope 2, in the sequence in which the power supply is turned off, the electric charge accumulated in the capacitor in the video signal line 20B is gradually discharged by the discharge circuit 25 with a predetermined time constant. In the present embodiment, the standby time for system control described above is set corresponding to the discharge time. That is, it is set corresponding to a slightly different discharge time for each model of the endoscope 2.
　この後、内視鏡２におけるＣＰＵ２１は、予め設定された所定の時間（当該内視鏡２における放電回路２５により映像信号ラインにおけるコンデンサに蓄積された電荷が十分に放電される時間）が経過した後、スコープ立ち下げが完了したことをビデオプロセッサ３側のスコープ制御回路３２に対して送信する（図６参照）。 After that, the CPU 21 in the endoscope 2 has elapsed a predetermined time (a time in which the electric charge accumulated in the capacitor in the video signal line by the discharge circuit 25 in the endoscope 2 is sufficiently discharged). After that, the fact that the scope shutdown is completed is transmitted to the scope control circuit 32 on the video processor 3 side (see FIG. 6).
　スコープ制御回路３２は、内視鏡２側からスコープ立ち下げ完了通知を受け取ると、当該情報をＣＰＵ３１に送信する。ＣＰＵ３１は、当該スコープ立ち下げ完了通知情報を受け取ると、表示部３６に対してスコープ抜去の許可を報知すべく、所定の報知情報を表示する。例えば、図６に示すように、表示部３６に対して"スコープ取り外し可能です"との表示を行う。 When the scope control circuit 32 receives the scope start-up completion notification from the endoscope 2 side, the scope control circuit 32 transmits the information to the CPU 31. When the CPU 31 receives the scope start-up completion notification information, the CPU 31 displays predetermined notification information in order to notify the display unit 36 of the permission to remove the scope. For example, as shown in FIG. 6, "the scope can be removed" is displayed on the display unit 36.
　ＣＰＵ３１は、一方で、モニタ機器５に対しても上記同様の"スコープ取り外し可能です"との表示を行うべく、画像処理部３５を制御する（図６参照）。 On the other hand, the CPU 31 controls the image processing unit 35 in order to display the same "scope can be removed" to the monitor device 5 as described above (see FIG. 6).
　なお、ビデオプロセッサ３側のＣＰＵ３１において、内視鏡取り外しボタン３７の押下後、上述したシステム制御の待機時間中に、上述したスコープ立ち下げ完了通知が得られない場合は、ユーザに対して、ビデオプロセッサ３の電源をオフして内視鏡２を抜去する旨を報知するようにしてもよい。 If the CPU 31 on the video processor 3 side does not obtain the above-mentioned scope start-up completion notification during the above-mentioned system control standby time after pressing the endoscope removal button 37, the user is notified of the video. The power of the processor 3 may be turned off to notify that the endoscope 2 is to be removed.
　また、内視鏡２の抜去許可の報知は、表示部３６またはモニタ５等への表示に限らず、映像、音声等でユーザに対して報知してもよい。 Further, the notification of the removal permission of the endoscope 2 is not limited to the display on the display unit 36 or the monitor 5, and may be notified to the user by video, audio, or the like.
　＜第１の実施形態の変形例＞
　図７および図８は、第１の実施形態に係る内視鏡システムの変形例の構成を示す図である。 <Modified example of the first embodiment>
7 and 8 are diagrams showing a configuration of a modified example of the endoscope system according to the first embodiment.
　図７、図８に示すように、当該変形例は、ビデオプロセッサ３における映像信号ライン３０Ｂ（図８参照）にも、放電回路３４が接続されていることを特徴とする。この放電回路３４は、映像信号ライン３０Ｂ上に直列に配設されたコンデンサ３０Ｃの出力端子とグランド間に接続されたプルダウン抵抗として構成され、上述した放電回路２５を同様の作用効果を奏する。 As shown in FIGS. 7 and 8, the modified example is characterized in that the discharge circuit 34 is also connected to the video signal line 30B (see FIG. 8) in the video processor 3. The discharge circuit 34 is configured as a pull-down resistor connected between the output terminal of the capacitor 30C arranged in series on the video signal line 30B and the ground, and the above-mentioned discharge circuit 25 has the same effect.
　＜第１の実施形態の効果＞
　本第１の実施形態の内視鏡システムによると、活線状態にあるビデオプロセッサから内視鏡を抜去する際、ビデオプロセッサ３に配設された内視鏡取り外しボタン３７を操作するだけで、当該ビデオプロセッサの電源をオフすることなく、コンデンサにチャージされた電荷を適切に放電されると共に抜去のタイミングが適切に表示されるので、術中の内視鏡の交換等の場面において、ユーザは、迅速にかつ適切に内視鏡を抜去することができる。 <Effect of the first embodiment>
According to the endoscope system of the first embodiment, when removing the endoscope from the live-lined video processor, it is only necessary to operate the endoscope removal button 37 provided on the video processor 3. Since the charge charged in the condenser is properly discharged and the timing of removal is properly displayed without turning off the power of the video processor, the user can use the user in a situation such as replacement of an endoscope during an operation. The endoscope can be removed quickly and appropriately.
　＜第２の実施形態＞
　次に、本発明の第２の実施形態の内視鏡システムについて図９、図１０を参照して説明する。 <Second embodiment>
Next, the endoscope system of the second embodiment of the present invention will be described with reference to FIGS. 9 and 10.

It is a timing chart.
　本第２の実施形態の内視鏡システム１は、基本的な構成は第１の実施形態と同様のであるので、ここでは差異のみの説明に留め、共通する部分の説明は省略する。 Since the basic configuration of the endoscope system 1 of the second embodiment is the same as that of the first embodiment, only the differences will be described here, and the common parts will be omitted.
　本第２の実施形態の内視鏡システム１においては、ビデオプロセッサ３から内視鏡２を抜去する際、前記内視鏡取り外しボタン３７による取り外し操作を要しないことを特徴とする。これにより、第２の実施形態に係るビデオプロセッサ３には、第１の実施形態においては表示部３６に設けられた内視鏡取り外しボタン３７を備えない。 The endoscope system 1 of the second embodiment is characterized in that when the endoscope 2 is removed from the video processor 3, the removal operation by the endoscope removal button 37 is not required. As a result, the video processor 3 according to the second embodiment does not include the endoscope removal button 37 provided on the display unit 36 in the first embodiment.
　また、第２の実施形態の内視鏡システムにおいては、ビデオプロセッサ３から内視鏡２を抜去し、さらに、当該内視鏡２をビデオプロセッサ３に再接続する際において、当該内視鏡２の映像信号ラインに電荷が蓄積されているか否かは問わず、ビデオプロセッサ３に接続（または再接続）された内視鏡２に蓄積された電荷を的確に放電することを可能とする。 Further, in the endoscope system of the second embodiment, when the endoscope 2 is removed from the video processor 3 and the endoscope 2 is reconnected to the video processor 3, the endoscope 2 is used. Regardless of whether or not the charge is accumulated in the video signal line of the above, it is possible to accurately discharge the charge accumulated in the endoscope 2 connected (or reconnected) to the video processor 3.

　本第２の実施形態の内視鏡システム１では、ＣＰＵ３１が、検知部３３からの検知結果に基づいて、内視鏡２がビデオプロセッサ３に接続（再接続を含む）されたことを検知すると、一旦システム制御を待機状態にした後、スコープ制御回路３２に対してスコープ立ち下げの処理を指示する（図１０参照）。スコープ制御回路３２は、このＣＰＵ３１からのスコープ立ち下げ指示を受けると、接続された内視鏡２（電荷が蓄積されているか否かは問わない）に対する電源供給をオフするようスコープ立ち下げ制御を実行する（図１０参照）。 In the endoscope system 1 of the second embodiment, when the CPU 31 detects that the endoscope 2 is connected (including reconnection) to the video processor 3 based on the detection result from the detection unit 33. After the system control is once put into the standby state, the scope control circuit 32 is instructed to process the scope down (see FIG. 10). When the scope control circuit 32 receives the scope start-up instruction from the CPU 31, the scope control circuit 32 controls the scope start-up so as to turn off the power supply to the connected endoscope 2 (whether or not the electric charge is accumulated). Execute (see FIG. 10).
　ここで、第１の実施形態と同様に、内視鏡２においては、電源供給がオフするシーケンスにおいて、映像信号ライン２０Ｂにおけるコンデンサに蓄積された電荷が放電回路２５により所定の時定数を伴って徐々に放電される。なお、本第２の実施形態においても、第１の実施形態同様に、システム制御の待機時間は適切に設定される。 Here, as in the first embodiment, in the endoscope 2, in the sequence in which the power supply is turned off, the electric charge accumulated in the capacitor in the video signal line 20B is accompanied by a predetermined time constant by the discharge circuit 25. It is gradually discharged. In the second embodiment as well, the standby time for system control is appropriately set as in the first embodiment.
　この後、第２の実施形態においても、内視鏡２におけるＣＰＵ２１は、予め設定された所定の時間（当該内視鏡２における放電回路２５により映像信号ラインにおけるコンデンサに蓄積された電荷が十分に放電される時間）が経過した後、スコープ立ち下げが完了したことをビデオプロセッサ３側のスコープ制御回路３２に対して送信する。 After that, also in the second embodiment, the CPU 21 in the endoscope 2 is sufficiently charged for a predetermined time set in advance (the charge accumulated in the capacitor in the video signal line by the discharge circuit 25 in the endoscope 2). After the time for discharging) has elapsed, the fact that the scope has been shut down is transmitted to the scope control circuit 32 on the video processor 3 side.
　スコープ制御回路３２は、内視鏡２側からスコープ立ち下げ完了通知（放電完了）を受け取ると、当該情報をＣＰＵ３１に送信する。ＣＰＵ３１は、当該スコープ立ち下げ完了通知情報を受け取ると、次に、スコープ制御回路３２に対して、当該内視鏡２に係るスコープ立ち上げ処理を指示する（図１０参照）。 When the scope control circuit 32 receives the scope start-up completion notification (discharge completion) from the endoscope 2 side, the scope control circuit 32 transmits the information to the CPU 31. Upon receiving the scope start-up completion notification information, the CPU 31 then instructs the scope control circuit 32 to perform the scope start-up process related to the endoscope 2 (see FIG. 10).
　内視鏡２におけるＣＰＵ２１は、スコープ制御回路３２からのスコープ立ち上げ指示を受けて、内視鏡２における各部に対して所定の立ち上げ処理を実行する。 The CPU 21 in the endoscope 2 receives a scope start-up instruction from the scope control circuit 32 and executes a predetermined start-up process for each part of the endoscope 2.
　一方でビデオプロセッサ３におけるＣＰＵ３１は、この立ち上げ処理が完了すると、内視鏡２に対して通常の制御を実行するべく、スコープ制御回路３２を制御する。 On the other hand, when the start-up process is completed, the CPU 31 in the video processor 3 controls the scope control circuit 32 in order to execute normal control on the endoscope 2.
　なお、第２の実施形態においても、ビデオプロセッサ３側に、第１の実施形態の変形例如き放電回路３４を設けてもよい。 Also in the second embodiment, the discharge circuit 34 as in the modified example of the first embodiment may be provided on the video processor 3 side.
　＜第２の実施形態の効果＞
　本第２の実施形態の内視鏡システムによると、ビデオプロセッサに内視鏡を接続する際、接続された内視鏡に対して、当該内視鏡における電荷の蓄積の有無を問わず、一旦立ち下げ処理を施した（同時に放電処理を施す）後に、立ち上げ処理を施すので、たとえ接続された内視鏡に電荷が蓄積されていた場合であっても、内設するＩＣ等にダメージを与えることなく当該接続された内視鏡を的確に駆動制御することができる。 <Effect of the second embodiment>
According to the endoscope system of the second embodiment, when an endoscope is connected to a video processor, the connected endoscope is once charged regardless of the presence or absence of charge accumulation in the endoscope. Since the start-up process is performed after the start-up process is performed (the discharge process is performed at the same time), even if the charge is accumulated in the connected endoscope, the internal IC etc. will be damaged. It is possible to accurately drive and control the connected endoscope without giving it.
　＜第３の実施形態＞
　次に、本発明の第３の実施形態の内視鏡システムについて、図１１を参照して説明する。 <Third embodiment>
Next, the endoscope system according to the third embodiment of the present invention will be described with reference to FIG.
　図１１は、本発明の第３の実施形態に係る内視鏡システムの構成を示すブロック図であり、図１２は、第３の実施形態に係る内視鏡システムにおける急速放電回路の構成を示す回路図である。 FIG. 11 is a block diagram showing the configuration of the endoscope system according to the third embodiment of the present invention, and FIG. 12 shows the configuration of the fast discharge circuit in the endoscope system according to the third embodiment. It is a circuit diagram.
　本第３の実施形態の内視鏡システム１は、基本的な構成は第２の実施形態と同様のであるので、ここでは差異のみの説明に留め、共通する部分の説明は省略する。 Since the basic configuration of the endoscope system 1 of the third embodiment is the same as that of the second embodiment, only the differences will be described here, and the common parts will be omitted.
　本第３の実施形態の内視鏡システム１は、図９に示すように、ビデオプロセッサ３における映像信号ラインに、急速放電回路３９が接続されていることを特徴とする。この急速放電回路３９は、図１０に示すように、例えばＦＥＴ等の半導体スイッチ４１と、当該半導体スイッチ４１に直列に接続された低抵抗４０とで構成され、映像信号ライン上に直列に配設されたコンデンサの出力端子とグランド間に接続されるようになっている。 As shown in FIG. 9, the endoscope system 1 of the third embodiment is characterized in that a fast discharge circuit 39 is connected to a video signal line in the video processor 3. As shown in FIG. 10, the fast discharge circuit 39 is composed of, for example, a semiconductor switch 41 such as an FET and a low resistance 40 connected in series with the semiconductor switch 41, and is arranged in series on a video signal line. It is designed to be connected between the output terminal of the capacitor and the ground.
　また、前記半導体スイッチ４１は、ＣＰＵ３１の制御によるオンオフが制御されるようになっている。また、低抵抗４０は、十分に低い抵抗値により構成され、少なくとも、第１、第２の実施形態における放電回路２５におけるプルダウン抵抗に比べてはるかに低い抵抗値に設定される。 Further, the semiconductor switch 41 is controlled to be turned on and off by the control of the CPU 31. Further, the low resistance 40 is composed of a sufficiently low resistance value, and is set to at least a much lower resistance value than the pull-down resistance in the discharge circuit 25 in the first and second embodiments.
　上述した第１、第２の実施形態における放電回路２５におけるプルダウン抵抗は、比較的大きな容量であって、かつ、配置する映像信号ラインの動作に影響を与えない、例えば１０ｋΩ程度の抵抗値に設定されることから、その放電時間もこれらの値に応じた時間を要していた（すなわち、極めて短時間とはいえない）。 The pull-down resistor in the discharge circuit 25 in the first and second embodiments described above has a relatively large capacitance and does not affect the operation of the video signal line to be arranged, for example, is set to a resistance value of about 10 kΩ. Therefore, the discharge time also required a time corresponding to these values (that is, it cannot be said to be an extremely short time).
　これに対して、本第３の実施形態における急速放電回路３９は、ＣＰＵ３１のオンオフ制御により極短時間での放電が可能である。これにより、ビデオプロセッサ３に内視鏡２が接続された際の立ち下げシーケンスを極短時間で終えることができ、スコープ立ち上げまでの時間を短縮することができる。 On the other hand, the fast discharge circuit 39 in the third embodiment can discharge in an extremely short time by on / off control of the CPU 31. As a result, the shutdown sequence when the endoscope 2 is connected to the video processor 3 can be completed in an extremely short time, and the time until the scope startup can be shortened.
　＜第３の実施形態の効果＞
　本第３の実施形態の内視鏡システムによると、第２の実施形態と同様の効果を奏し、さらに、立ち下げ処理（放電処理）を短時間で実行することできることから、スコープ立ち上げまでの時間を短縮することができる。 <Effect of the third embodiment>
According to the endoscope system of the third embodiment, the same effect as that of the second embodiment can be obtained, and the down-down processing (discharge processing) can be executed in a short time, so that the scope can be started up. You can save time.
　＜第４の実施形態＞
　次に、本発明の第４の実施形態の内視鏡システムについて、図１３を参照して説明する。 <Fourth Embodiment>

　本第４の実施形態の内視鏡システム１は、ビデオプロセッサから内視鏡に対していわゆる無線給電により電力を供給することを特徴とする。 The endoscope system 1 of the fourth embodiment is characterized in that power is supplied from the video processor to the endoscope by so-called wireless power supply.
　図１３に示すように、第４の実施形態の内視鏡システム１におけるビデオプロセッサ３は、内視鏡２に対して無線給電により電力を供給する給電部８１を備える。 As shown in FIG. 13, the video processor 3 in the endoscope system 1 of the fourth embodiment includes a power supply unit 81 that supplies electric power to the endoscope 2 by wireless power supply.
　一方、本実施形態における内視鏡２は、無接点部６１を介して電力を受電する受電部９１を備える。さらに内視鏡２は、受電部９１で受電した電力を整流する整流回路９２、整流された電圧をＣＰＵ２１の制御を受けて定電圧化するリニアレギュレータＬＤＯ９３を備える。 On the other hand, the endoscope 2 in the present embodiment includes a power receiving unit 91 that receives electric power via the non-contact unit 61. Further, the endoscope 2 includes a rectifier circuit 92 that rectifies the electric power received by the power receiving unit 91, and a linear regulator LDO 93 that converts the rectified voltage into a constant voltage under the control of the CPU 21.
　このＬＤＯ９３の電圧は電圧検出部９６により検出され、Ａ／Ｄ９５によりＡＤ変換された後、変復調回路９４からビデオプロセッサ３における変復調回路８２に送信され、さらにビデオプロセッサ３におけるＣＰＵ３１に送信されるようになっている。一方、ビデオプロセッサ３におけるＣＰＵ３１からは、送信機ＴＸ８３，受信機ＲＸ９７を介して、所定の駆動制御信号が撮像素子２２に対して伝送されるようになっている。 The voltage of the LDO 93 is detected by the voltage detection unit 96, AD-converted by the A / D 95, transmitted from the modulation / demodulation circuit 94 to the modulation / demodulation circuit 82 in the video processor 3, and further transmitted to the CPU 31 in the video processor 3. It has become. On the other hand, a predetermined drive control signal is transmitted from the CPU 31 in the video processor 3 to the image sensor 22 via the transmitter TX83 and the receiver RX97.
　また、本第４の実施形態においては、上述した検知部３３と同様の検知機能を有する検知部を備えると共に、内視鏡２側に、第３の実施形態における急速放電回路３９と同様の構成をなす放電回路９８が図示しない映像信号ラインに接続されている。 Further, in the fourth embodiment, a detection unit having the same detection function as the detection unit 33 described above is provided, and the endoscope 2 side has the same configuration as the fast discharge circuit 39 in the third embodiment. The discharge circuit 98 is connected to a video signal line (not shown).
　＜第４の実施形態の作用＞
　以下、本第４の実施形態の内視鏡システム１における作用について説明する。 <Operation of the fourth embodiment>
Hereinafter, the operation of the endoscope system 1 of the fourth embodiment will be described.
　本第４の実施形態の内視鏡システム１では、検知部によりビデオプロセッサ３が内視鏡２の接続が検知されると、放電回路９８により内視鏡２における残留電荷が完全に放電される。その後、ビデオプロセッサ３における給電部８１から受電部９１に対して給電される。 In the endoscope system 1 of the fourth embodiment, when the video processor 3 detects the connection of the endoscope 2 by the detection unit, the discharge circuit 98 completely discharges the residual charge in the endoscope 2. .. After that, power is supplied from the power feeding unit 81 in the video processor 3 to the power receiving unit 91.
　この給電が開始されると、内視鏡２におけるＣＰＵ２１は、撮像素子２２に供給する電源の状態を確認してからＬＤＯ９３の電源を投入する。この後、電圧検出部９６においてＬＤＯ９３に供給される電源の状態を確認した後、ビデオプロセッサ３にけるＣＰＵ３１は、ＣＰＵ３１が、送信機ＴＸ８３，受信機ＲＸ９７を介して、所定の駆動制御信号を撮像素子２２に対して送信する。 When this power supply is started, the CPU 21 in the endoscope 2 turns on the power of the LDO 93 after confirming the state of the power supply supplied to the image sensor 22. After that, after the voltage detection unit 96 confirms the state of the power supply supplied to the LDO 93, the CPU 31 in the video processor 3 captures a predetermined drive control signal via the transmitter TX83 and the receiver RX97. It transmits to the element 22.
