Description

【0001】
【発明の属する技術分野】
本発明は充電器等のエネルギ発生ユニットと非接触で手術具に内蔵した2次電池を充電する手術装置に関する。
【0002】
【従来の技術】
近年、内視鏡による観察下等により、切開する部分を最小限に押さえて、短期間で完治ができるような外科手術が広く行われるようになった。
例えば特公平2−43501号に開示された従来の手術具ではハンドピース内に電池が設けられており、更にモータと処置具が一体的に設けられており、そのモータは内蔵された電池で動作するようになっている。
【0003】
【発明が解決しようとする課題】
上記従来例は操作する場合、邪魔になり易い電源コードを不必要にして操作性を向上できるが、その問題点として電池がなくなってしまうと処置が出来なくなる欠点がある。
【0004】
この場合、特に手術中に電池交換を行わなければならなくなることを回避するには、手術前に電池交換を行っておくことが必要になるが、このような作業は煩わしいものとなるし、一部使用しただけで電池交換が必要でない可能性があるような場合にも、手術中での電池交換を回避するためには交換することが必要となってしまう。
【0005】
また、滅菌処理された手術具の電池交換を行う場合には、汚染しないように細心の注意が必要となり、看護婦等に非常に負担を強いる欠点がある。
このため、手術具に充電可能な電池を内蔵し、充電器で充電することにより、対応することが考えられるが、従来例では充電器を接続することにより、滅菌された手術具を汚染してしまう欠点があった。
【0006】
(発明の目的)
本発明は、上述した点に鑑みてなされたもので、滅菌処理された手術具を汚染することなく充電することができ、手術中における電池交換を殆ど不必要にできる手術装置を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明は、充電可能な2次電池及び該2次電池により電気的に駆動される処置部とを有し、消毒或いは滅菌可能な手術具と、前記手術具の外部に配置され、前記2次電池を充電するためのエネルギ発生ユニットを内設する充電装置と、前記エネルギ発生ユニットに設けられた、エネルギを送出する送電コイルを有するエネルギ送出手段と、前記手術具に設けられた、前記エネルギ発生ユニットと非接触で前記送出エネルギを受ける受電コイルを有するエネルギ受電手段と、前記手術具に設けられた、前記エネルギ受電手段で受けた前記送出エネルギから前記2次電池を充電する充電エネルギを生成する充電エネルギ生成手段と、前記充電装置の上面に配置可能であって、前記手術具を当該手術具の長軸方向と載置面とが略平行になるように載置可能な滅菌トレーと、を備え、前記手術具を、前記滅菌トレーの載置面に当該手術具の長軸方向と当該載置面とが略平行になるように載置した際、前記受電コイルの軸の向きと前記送電コイルの軸の向きとが平行となることを特徴とする。
【0008】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態を説明する。
(第1の実施の形態)
図1ないし図5は本発明の第1の実施の形態に係り、図1は第1の実施の形態を備えた手術システムの構成を示し、図2は充電している状態での構成を示し、図3は非接触で充電する場合の動作原理、手術具及び充電器の電気系の構成を示し、図4は手術具の構成例を示し、図5は変形例の手術具及び充電器の電気系の構成を示す。
【0009】
図1及び図2に示す手術システム1は充電を行うためのエネルギを発生すると共にそのエネルギを放射する機能を備えたエネルギ発生ユニットとしての充電器2と、手術を行うための手術具3A或いは3Bとからなり、手術具3A或いは3Bには前記充電器2からのエネルギを前記充電器2と非接触で受け、充電可能な2次電池4を充電する充電エネルギ生成手段をそれぞれ内蔵している。
【0010】
また、手術具3A及び3Bは、術者により把持される把持部5と、この把持部5から突出する軸部6とを有し、この軸部6の先端には生体組織に対して処置を行う処置部7A或いは7Bが設けてある。
【0011】
また、把持部5にはスイッチ8が設けてあり、このスイッチ8をON、OFFすることにより、処置部7A或いは7Bを駆動或いは駆動停止させることができるようにしている。
【0012】
充電器2は商用電源に接続する電源コード11を有し、この電源コード11の先端のプラグ12を商用電源のコンセントに接続することにより、商用電源から交流の電気エネルギが電源スイッチ14を介して出力回路15に供給される。
この出力回路15はこの交流の電気エネルギを例えばより高い周波数の電気エネルギに変換して出力端から、その出力端に接続された送電回路16(を構成する送電コイル16a)に出力する。
【0013】
上記出力回路15は例えば図3(B)に示すように電源回路15aと、この電源回路15aにより生成された直流の電圧で発振する発振回路15bと、電源回路からの直流の電源が供給され、発振回路15bの発振信号を増幅するアンプ15cとから構成され、このアンプ15cの出力端に送電回路16(を構成する送電コイル16a)が接続されている。
【0014】
発振回路15bは例えば数10kHzから数MHzの周波数で発振し、この高周波信号をアンプ15cで増幅し、送電手段である送電コイル16aに送る。
そして、この送電コイル16aから、その周囲に電磁エネルギを放射するようにしている。
【0015】
なお、図2に示すように充電器2の上部には洗滌及び消毒(或いは滅菌)等がされた清浄な手術具3A及び3B等を入れるカップ17を載置できるように凹部形状のカップ載置部18が設けてある。このカップ17は洗滌及び消毒(或いは滅菌)等が可能である。
また、充電器2の送電コイル16aが埋め込まれた部材と、カップ17は電磁エネルギを透過する素材、例えばガラス或いはテフロン等の樹脂である。
【0016】
そして、清浄にしたこのカップ17に手術具3A及び3B等を入れ、充電器2により、手術具3A及び3Bに非接触で手術具3A及び3Bの2次電池4を充電することができるようにしている。
【0017】
一方、例えば手術具3Aは図2に示すように送電回路16から放射されて電磁エネルギを受ける受電部21と、この受電部21で受電した電磁エネルギを直流の電気エネルギに変換すると共に、充電するのに適した電圧に設定する制御とを行う整流・制御部22と、この整流・制御部22の出力で充電される2次電池4と、この2次電池4により駆動されるエネルギ変換部23と、このエネルギ変換部23により直接或いは伝達部材としての軸部6を介して駆動される例えばメス型の処置部7Aとを有する。
【0018】
この手術具3Aが例えば超音波メスの場合には、エネルギ変換部23の構成は図4(A)に示すように超音波発振回路23a及び超音波振動子(図3では単に振動子と略記)23bとなる。
【0019】
図1ではこの手術具3Aが例えば超音波メスの場合でのより具体的な構成を示している。
この手術具3Aはその把持部5の後端付近に電池収納室31が設けられ、この電池収納室31の後端は開口し、雌ネジを設けた蓋32と螺合する雄ネジが設けてある。また、蓋32と嵌合する嵌合部の途中に水密用のOリング等のシール部材33が設けてあり、蓋32を取り付けた状態では内部を水密に保持できるようにしている。
【0020】
また、電池収納室31の周囲には受電部21を形成する受電コイル21aが配置され、この受電コイル21aで誘起した電気エネルギはリード線を介して整流・制御部22に入力され、この整流・制御部22で2次電池4を充電するのに適した電圧に設定されて2次電池4に供給される。
【0021】
この2次電池4はスイッチ8を介して超音波発振回路23aと接続され、この超音波発振回路23aの出力端に超音波振動子23bが接続されており、超音波発振回路23aの出力信号が印加されることにより、超音波振動子23bは超音波で振動する。
なお、図1では受電コイル21a、整流・制御部22、超音波発振回路23aは絶縁部材内部に埋め込まれている。
【0022】
この超音波振動子23bの前端はホーン34を介して把持部5から突出する軸部6と接続されており、超音波振動子23bによる超音波振動をホーン34で増幅し、さらに軸部6を介してその先端の処置部7Aに超音波振動を伝達する。
なお、ホーン34の前端と軸部6との接続部はゴム部材等のシール部材35を介して把持部5のカバー部材(外装部材)で覆われるようにしており、把持部5の内部は洗滌液での洗滌はもとより、消毒液(或いは滅菌液)での消毒(或いは滅菌)ができるように水密構造になっている。また、滅菌ガスでの滅菌に対する耐性も有するようにしている。
【0023】
つまり、本実施の形態における手術具3Aは洗滌はもとより、消毒或いは滅菌が可能である。
なお、把持部5から突出する軸部6をシールする場合、図3(A)に示すようにホーン34の基端側でシールするようにしても良い。
【0024】
図3(C)は手術具3Aの電気系のより具体的な構成例を示している。
つまり、受電コイル21aの両端は整流・制御部22を構成する整流回路22aの入力端に接続され、整流及び平滑化された後、定電圧ダイオード22bによる定電圧化された後、逆流防止用ダイオード22cを介して2次電池4に接続されている。
【0025】
また、この2次電池4はその一端が直接、他端がスイッチ8を介して超音波発振回路23aの入力端に接続され、この超音波発振回路23aの出力端には超音波振動子23bが接続されている。
【0026】
なお、手術具3Bは例えば手術具3Aより長い軸部6でその先端の処置部7Bが例えば鍵型である他は手術具3Aと同様の構成であり、手術具3Aと同様に消毒等が可能である。
【0027】
また、上述の説明では手術具3A或いは3Bが超音波メスの場合で説明したが、図4(B)に示すように電気メス3Cでも良いし、図4(C)に示すモータ式処置具3Dでも良い。
【0028】
図4(B)に示すように電気メス3Cは図4(A)に示す超音波メス3Aにおける超音波発振回路の代わりに高周波出力回路23cが設けられ、高周波で発振し、かつその発振出力を増幅して出力する。この高周波出力回路23cの出力端は出力トランス23dの1次側が接続され、その2次側に1次側と絶縁された高周波出力信号を出力する。
【0029】
この出力トランス23dの2次側の端子には1対の高周波電極棒36a,36bが接続され、その先端側の処置部7Cに高周波出力信号を伝達する。そして、処置部7Cを処置したい生体組織に接触させることにより、切除とか焼灼することができるようにしている。
【0030】
なお、把持部5から高周波電極棒36a,36bが突出する部分には絶縁部材37で水密及び気密構造にされている。
【0031】
また、図4(C)に示すモータ式処置具3Dは図4(A)に示す超音波メス3Aにおける超音波発振回路23aの代わりにモータ制御部23eが設けてあり、このモータ制御部23eの出力信号でモータ23fを回転駆動するようにしている。
【0032】
このモータ23fの回転軸には把持部5から突出する軸部38が接続され、この軸部38の先端に処置部としての回転ブラシ39が設けてあり、生体組織を剥離する等の処置を行えるようにしている。
【0033】
なお、把持部5から軸部38が突出する部分にはOリング等のシール部材40が介挿され、水密を保持している。
このような構成の第1の実施の形態による作用を説明する。
【0034】
図1に示す処置具3A及び3Bを使用して手術を行う場合には、蓋32を開けて電池収納室31に2次電池4を収納し、蓋32を閉める。この状態では処置具3A及び3Bは水密構造及び気密構造であり、洗滌及び消毒(或いは滅菌)が可能である。
【0035】
そして、手術具3A及び3Bを洗滌及び消毒(或いは滅菌)して、図2に示すように充電器2の上部のカップ載置部18に載置された洗滌及び消毒(或いは滅菌)されたカップ17に入れる。
【0036】
そして、充電器2のプラグ12を商用コンセントに接続してスイッチ14をONすることにより、図3(B)に示す充電器2の出力回路15を構成する発振回路15bの発振信号がアンプ15cで増幅されて送電コイル16aに印加され、この送電コイル16aの周囲に時間的に変化する電磁界を生成し、その電磁界により、受電コイル21aに時間的に変化する起電力が発生する。
【0037】
つまり、図3(A)に示すように高周波信号を送電コイル16aに印加することにより、その周囲に配置した受電コイル21aに高周波信号が発生する(電磁誘導方式)。このようにして、電気的に非接触な状態で、受電コイル21aにエネルギを伝達する。
【0038】
図3(C)に示すように受電コイル21aの高周波信号は整流・制御部22に供給され、整流回路22aで整流され、さらに充電に適した電圧にされて2次電池4に供給され、この2次電池4を充電する。
【0039】
従って、充電に必要とされる時間の後には、2次電池4により手術を行うことができる状態になる。従って、このカップ17から例えば手術具3Aを取り出して術者はその把持部5を把持してスイッチ8のONスイッチを押すと2次電池4から超音波発振回路23aに駆動電源が供給されて超音波発振し、その超音波発振出力が超音波振動子23bに印加されることにより、超音波振動子は超音波振動し、軸部6によりその先端の処置部7Aに伝達され、処置部7Aを生体組織に接触させることにより、切除等の処置を行うことができる。
【0040】
また、使用後は、処置具3Aを洗滌及び消毒(或いは滅菌)して、再びカップ17内にいれて同様に充電することができる。
【0041】
上記の構成で手術具3A等の内部に設けられた2次電池4を充電する事によって手術具3A等を繰り返して使用する事が出来る。手術具3A等は使用する毎に洗浄・滅菌する必要があり、充電器2は不潔状態なので、充電器2に予め洗浄・滅菌したカップ17をセットして、カップ17の中に手術具3A等を入れるようにする事で手術具3A等の滅菌状態を保持した状態で非接触で充電することができる。
【0042】
尚、他のエネルギ伝送の手段として、図5(A)、(B)に示す変形例のようなものでも良い。
図5(A)では、電源回路15aの直流電源で例えば発光ダイオード(LEDと略記)16b等の発光手段を発光させて、このLED16bの光を太陽電池21bなどの光電変換素子で受けて直流の起電力を発生させ、その起電力を制御部を構成する定電圧ダイオード22b及び逆流防止ダイオード22cを経て2次電池4を充電するようにしても良い。
【0043】
なお、この場合には、図3(B)に示す充電器2の電気系の構成は出力回路15が電源回路15aで構成され、送電回路16がLED16bで構成されることになる。また、手術具側は受電部21が太陽電池21bで構成され、整流・制御部22が整流を必要としない制御部で構成される。
【0044】
また、この場合には、充電器2におけるLED16bを配置した部分の上部側の光出射部分と、カップ17とはLED16bの光を透過するガラス等の素材を用いると良い。また、太陽電池21bは手術具の後端の例えば蓋32に設けられ、受光部が外表面に望むように設ける。
この場合にも、充電器2と非接触で2次電池4を充電することができる。
【0045】
また、図5(B)に示すように、電源回路15aの直流電源で発振回路15bを発振させ、この発振出力で超音波スピーカ16c等の送音器から超音波エネルギ等の音響エネルギを送出させ、その音響エネルギを超音波マイク21c等の受音器で受けて電気エネルギに変換し、それを整流・制御部22を介して2次電池4を充電する手段でも良い。
【0046】
本実施の形態は以下の効果を有する。
第1の実施の形態によれば、電池駆動式の手術具3A等に内蔵された2次電池4を繰り返し充電する事によって、手術具3A等を繰り返し使用可能であり、且つ、充電の際に電気的に接続する接点等が不要で非接触で充電できるので、滅菌状態を維持して充電する事が可能であり、手術中に電池切れ(電気エネルギが不足)するようなことを殆ど解消できる。
【0047】
(第2の実施の形態)
次に本発明の第2の実施の形態を図6及び図7を参照して説明する。図6は第2の実施の形態における処置具3Eの構成を示し、図6は処置具3Eの電気系の構成を示す。本実施の形態は例えば第1の実施の形態の処置具3Aにおいて、充電動作が完了したことを示す手段を設けたものである。
【0048】
本実施の形態における処置具3Eを図6に示す。この処置具3Eは図1の処置具3Aにおいて、把持部5内の整流・制御部22の代わりに、この整流・制御部22に充電状態判別部41を設けた整流・制御・判別部42とし、把持部5の外表面にこの整流・制御・判別部42に接続された充電完了表示用LED43が設けてある。
【0049】
この処置具3Eの電気系の構成を図7に示す。図7に示すように整流回路22aの出力端は充電状態判別部41を構成するコンパレータ41aの正負の電源端に接続されると共に、電流制限用抵抗R1を介して定電圧ダイオード22bが接続されている。
【0050】
また、定電圧ダイオード22bのカソードは切換スイッチSW及び逆流防止用ダイオード22cを介して2次電池4のアノードと接続されている。
また、コンパレータ41aの非反転入力端には2次電池4のアノードの電圧が印加され、コンパレータ41aの反転入力端には定電圧ダイオード22bで安定化された電圧を抵抗R2,R3で分割した基準電圧が印加される。
【0051】
このコンパレータ41aの出力端には抵抗R4及びコンデンサCが接続され、2次電池4の電圧が基準電圧を越えた場合にこのコンデンサCを充電した電圧で切換スイッチSWを接点aから接点bに切換え、接点bに接続されたLED43を発光させるようにしている。
【0052】
なお、この基準電圧は2次電池4の充電動作が完了した場合の電圧となるように抵抗R2,R3の値が設定されている。
また、切換スイッチSWは例えばアナログスイッチで構成され、その電源はコンパレータ41と同様に整流回路22aから供給される(図7では簡単化のため、省略)。その他は第1の実施の形態と同様の構成である。
【0053】
本実施の形態によれば、第1の実施の形態と同様の作用を有する他に、充電した場合に、2次電池4の充電動作が完了した状態になると、その状態を2次電池の電圧が基準電圧を越えたことにより検出し、切換スイッチSWを切り換えて2次電池4に充電電流が流れないようにすると共に、LED43を発光(点灯)させるようになる。
【0054】
このため、術者等はこのLED43の点灯により、その手術具3Eが充電動作が完了した状態であることを確認することができる。従って、術者はLED43が点灯した手術具を使用すれば良く、この場合には手術中に電池切れが発生することをより確実に防止できる。
【0055】
また、過度に2次電池4を充電してしまうようなことを防止できる(過度の充電で2次電池4を速く劣化させてしまうことを防止できる)し、充電器2の電源を入れた状態にしたままでも過度に2次電池4を充電してしまうようなことを防止でき、使い勝手が向上する。
【0056】
従って、本実施の形態によれば、第1の実施の形態の効果の他に、2次電池4の充電完了状態か否かをLED43の点灯(非点灯)により容易に知ることができる。また、過充電を防止して、2次電池4の寿命の低下を防止できるし、充電器2の電源を入れっぱなしにしても2次電池4の寿命の低下を防止できる等、取り扱いも容易となる等の効果がある。
【0057】
なお、本実施の形態では、充電完了状態を検出する検出手段を設け、充電完了状態を検出した場合にはLED43を点灯させてユーザに充電完了状態を告知するようにしているが、充電中にLED43を点灯させ、充電完了状態にLED43を消灯させて充電中及び充電完了状態を告知するようにしても良い。
【0058】
この場合には、図7において、LED43のアノードをダイオード22cのアノードと共に、切換スイッチSWの接点aに接続すれば良い。また、充電中に充電中を示すLEDを点灯させ、充電完了状態に前記LEDとは発光する波長が異なるLED43を点灯させて充電中及び充電完了状態を告知するようにしても良い。
【0059】
この場合には、図7において、LED43を緑色で発光するLEDとし、この他に赤で発光するLEDのカソード及びアノードを図7のLED43のカソードと切換スイッチSWの接点aに接続すれば良い。
【0060】
(第3の実施の形態)
次に本発明の第3の実施の形態を図8及び図9を参照して説明する。
図8は、トレー型の手術システム51であって、充電器52とその充電器52を設置するためのカート53と充電器52の上に設置する滅菌トレー54と、この滅菌トレー54上に載置される電池駆動式手術具55とからなる。
【0061】
滅菌トレー54の中には電池駆動式手術具55や通常の手術具56が設置出来る。
充電器52からコード11が延出され、その先端にはプラグ12が設けてある。
【0062】
また、この充電器52は、第1の実施の形態と同様の構成であり、図9に示すように送電回路16が設けてあり、その上部側に配置される電池駆動式手術具55の内部に設けられている受電部21に非接触でエネルギを供給する。この受電部21で受けたエネルギは整流・制御部22を介して2次電池4に供給し、この2次電池4を充電する。
【0063】
尚、このようにトレー式の場合、手術具55の向きの自由度が大きいので、電池駆動式手術具55の内部に、おもり57が設けられており、送電回路16と受電部21との向きがエネルギの伝送を効率良く行うことができるように適切な向きとなるようになっている。例えば、送電回路16と受電部21とがコイルで構成された場合には、両コイルの軸方向が平行となるようにして、送電回路16のコイルで発生したエネルギを受電部21のコイルで効率良く受けることができるようにしている。
本実施の形態は以下の効果を有する。
本実施の形態によれば、大きな滅菌トレー54の中に自由な向きの処置具55を配置しても確実に充電が行われる。
【0064】
なお、第2の実施の形態のように2次電池4の充電動作が完了した状態になると、2次電池4に充電電流が流れないようにすると共に、LED43等でユーザに分かるように告知する手段を設けるようにしても良い。
【0065】
(第4の実施の形態)
次に図10ないし図12を参照して本発明の第4の実施の形態を説明する。
図10に示す第4の実施の形態の手術装置としての充電式の超音波凝固・切開手術装置61は、充電装置62と2次電池4(図11参照)を内蔵した超音波凝固・切開具63とからなる。
【0066】
充電装置62には、洗浄・滅菌可能な充電用ソケット64が組み付けられるようにソケット着脱用凹部62a(図12参照)が設けてある。
図12に示すように、充電用ソケット64は充電装置62に対して着脱可能になっている。
【0067】
手術の前に超音波切開・凝固具63と充電用ソケット64を滅菌しておき、使用する際に充電用ソケット64を充電装置62にセットした上で超音波凝固・切開具63を組み込んでおく。
【0068】
図11に示すように充電装置62には送電回路16として例えば2次側コイル67が組み込まれており、超音波切開・凝固具63には把持部5の外装ケース69内に設けた(受電部21としての)2次側コイル68が組み込まれており、電磁誘導によってエネルギが伝送され、2次側コイル68に接続された整流・制御部22で充電に適した電圧に変換されて2次電池4に供給され、この2次電池4を充電するようになっている。
【0069】
なお、充電用ソケット64は消毒、滅菌などに耐性を有するテフロン等の樹脂或いはセラミックス等で構成され、また電気的に絶縁性を有する。そして、1次コイル67と2次コイル68との間に充電用ソケット64を介在させても、1次コイル67による電磁エネルギを2次コイル68に伝送できるようにしている。
また、この2次電池4は図示しないスイッチを介して超音波発振回路23aに接続され、スイッチをONすると超音波発振回路23aの発振出力を超音波振動子23bに印加する。この超音波振動子23bによる超音波振動はホーン34及び軸部6を経て先端の処置部7Bを超音波振動させる。
【0070】
本実施の形態は以下の効果を有する。
本実施の形態は1次側コイル67と2次側コイル68との間に受電用ソケット64が配置されているので超音波凝固・切開具の滅菌状態を維持したまま充電が可能である。
【0071】

FIG. 3C shows a more specific configuration example of the electrical system of the surgical tool 3A.
That is, both ends of the power receiving coil 21a are connected to the input ends of the rectifier circuit 22a constituting the rectifier / control unit 22, and after rectification and smoothing, the voltage is constant by the constant voltage diode 22b, and then the reverse current prevention diode. It is connected to the secondary battery 4 through 22c.
[0025]
Further, one end of the secondary battery 4 is directly connected to the input end of the ultrasonic oscillation circuit 23a via the switch 8, and an ultrasonic transducer 23b is connected to the output end of the ultrasonic oscillation circuit 23a. It is connected.
[0026]
The surgical tool 3B has the same configuration as the surgical tool 3A except that the shaft part 6 is longer than the surgical tool 3A and the distal end treatment part 7B is, for example, a key type. It is.
[0027]
In the above description, the surgical instrument 3A or 3B is an ultrasonic scalpel, but an electric scalpel 3C may be used as shown in FIG. 4B, or a motor-type treatment tool 3D shown in FIG. 4C. But it ’s okay.
[0028]
As shown in FIG. 4 (B), the electric knife 3C is provided with a high frequency output circuit 23c instead of the ultrasonic oscillation circuit in the ultrasonic knife 3A shown in FIG. 4 (A), and oscillates at a high frequency and outputs its oscillation output. Amplify and output. The output end of the high-frequency output circuit 23c is connected to the primary side of the output transformer 23d, and outputs a high-frequency output signal insulated from the primary side to the secondary side.

A pair of high-frequency electrode rods 36a and 36b are connected to the secondary side terminal of the output transformer 23d, and a high-frequency output signal is transmitted to the treatment portion 7C on the distal end side. Then, the treatment section 7C is brought into contact with a living tissue to be treated so that excision or cauterization can be performed.

[0033]
A seal member 40 such as an O-ring is inserted in a portion where the shaft portion 38 protrudes from the grip portion 5 to maintain water tightness.
The effect | action by 1st Embodiment of such a structure is demonstrated.
[0034]
When performing surgery using the treatment tools 3A and 3B shown in FIG. 1, the lid 32 is opened, the secondary battery 4 is stored in the battery storage chamber 31, and the lid 32 is closed. In this state, the treatment tools 3A and 3B have a watertight structure and an airtight structure, and can be cleaned and disinfected (or sterilized).
[0035]
Then, the surgical tools 3A and 3B are cleaned and disinfected (or sterilized), and the cleaned and disinfected (or sterilized) cup placed on the cup mounting portion 18 on the upper part of the charger 2 as shown in FIG. Put in 17.
[0036]
Then, by connecting the plug 12 of the charger 2 to a commercial outlet and turning on the switch 14, the oscillation signal of the oscillation circuit 15b constituting the output circuit 15 of the charger 2 shown in FIG. The amplified electromagnetic field is applied to the power transmission coil 16a to generate a time-varying electromagnetic field around the power transmission coil 16a. The electromagnetic field generates a time-varying electromotive force in the power receiving coil 21a.
[0037]
That is, as shown in FIG. 3A, by applying a high-frequency signal to the power transmission coil 16a, a high-frequency signal is generated in the power receiving coil 21a disposed around it (electromagnetic induction method). In this way, energy is transmitted to the power receiving coil 21a in an electrically non-contact state.
[0038]
As shown in FIG. 3C, the high-frequency signal of the power receiving coil 21a is supplied to the rectifying / control unit 22, rectified by the rectifying circuit 22a, further converted to a voltage suitable for charging, and supplied to the secondary battery 4. The secondary battery 4 is charged.
[0039]
Therefore, after the time required for charging, the secondary battery 4 is ready for surgery. Accordingly, for example, when the surgical tool 3A is taken out from the cup 17 and the operator holds the holding part 5 and presses the ON switch of the switch 8, the driving power is supplied from the secondary battery 4 to the ultrasonic oscillation circuit 23a. The ultrasonic oscillator oscillates and the ultrasonic oscillation output is applied to the ultrasonic transducer 23b, so that the ultrasonic transducer vibrates ultrasonically and is transmitted to the treatment portion 7A at the distal end by the shaft portion 6 to pass through the treatment portion 7A. A treatment such as excision can be performed by contacting the living tissue.
[0040]
In addition, after use, the treatment tool 3A can be cleaned and disinfected (or sterilized), placed in the cup 17 again, and charged in the same manner.
[0041]
By charging the secondary battery 4 provided in the surgical instrument 3A or the like with the above configuration, the surgical instrument 3A or the like can be used repeatedly. The surgical instrument 3A and the like need to be cleaned and sterilized every time it is used, and the charger 2 is in an unclean state. It is possible to charge in a non-contact manner while maintaining the sterilized state of the surgical instrument 3A and the like.
[0042]
As other energy transmission means, the modification shown in FIGS. 5A and 5B may be used.
In FIG. 5A, a light source such as a light emitting diode (abbreviated as LED) 16b is caused to emit light by a direct current power source of a power supply circuit 15a, and the light of the LED 16b is received by a photoelectric conversion element such as a solar battery 21b. An electromotive force may be generated, and the secondary battery 4 may be charged with the electromotive force via a constant voltage diode 22b and a backflow prevention diode 22c that constitute a control unit.
[0043]
In this case, in the configuration of the electrical system of the charger 2 shown in FIG. 3B, the output circuit 15 is configured by the power supply circuit 15a, and the power transmission circuit 16 is configured by the LED 16b. On the surgical instrument side, the power receiving unit 21 is configured by a solar cell 21b, and the rectification / control unit 22 is configured by a control unit that does not require rectification.
[0044]
In this case, the light emitting portion on the upper side of the portion where the LED 16b is disposed in the charger 2 and the cup 17 may be made of a material such as glass that transmits the light of the LED 16b. Moreover, the solar cell 21b is provided on the lid 32, for example, at the rear end of the surgical instrument so that the light receiving portion is desired on the outer surface.
Also in this case, the secondary battery 4 can be charged without contact with the charger 2.
[0045]
Further, as shown in FIG. 5B, the oscillation circuit 15b is oscillated by a DC power source of the power supply circuit 15a, and acoustic energy such as ultrasonic energy is transmitted from the sound transmitter such as the ultrasonic speaker 16c by this oscillation output. The acoustic energy may be received by a sound receiver such as an ultrasonic microphone 21c and converted into electric energy, and the secondary battery 4 may be charged via the rectification / control unit 22.
[0046]
The present embodiment has the following effects.
According to the first embodiment, it is possible to repeatedly use the surgical instrument 3A and the like by repeatedly charging the secondary battery 4 incorporated in the battery-driven surgical instrument 3A and the like, and at the time of charging. It can be charged in a non-contact manner without the need for electrically connecting contacts, etc., so that it can be charged while maintaining sterilization, and almost all battery shortages (insufficient electrical energy) during surgery can be eliminated. .
[0047]
(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 6 shows the configuration of the treatment instrument 3E in the second embodiment, and FIG. 6 shows the configuration of the electrical system of the treatment instrument 3E. In the present embodiment, for example, in the treatment instrument 3A of the first embodiment, a means for indicating that the charging operation is completed is provided.
[0048]
A treatment instrument 3E in the present embodiment is shown in FIG. This treatment tool 3E is a rectification / control / discrimination unit 42 in which a charge state discrimination unit 41 is provided in the rectification / control unit 22 instead of the rectification / control unit 22 in the grasping unit 5 in the treatment instrument 3A of FIG. The charging completion display LED 43 connected to the rectifying / control / discriminating unit 42 is provided on the outer surface of the holding unit 5.
[0049]
The configuration of the electrical system of the treatment tool 3E is shown in FIG. As shown in FIG. 7, the output terminal of the rectifier circuit 22a is connected to the positive and negative power supply terminals of the comparator 41a constituting the charging state determination unit 41, and the constant voltage diode 22b is connected via the current limiting resistor R1. Yes.
[0050]
The cathode of the constant voltage diode 22b is connected to the anode of the secondary battery 4 through the changeover switch SW and the backflow prevention diode 22c.
The voltage of the anode of the secondary battery 4 is applied to the non-inverting input terminal of the comparator 41a, and the reference voltage obtained by dividing the voltage stabilized by the constant voltage diode 22b by the resistors R2 and R3 is applied to the inverting input terminal of the comparator 41a. A voltage is applied.
[0051]
A resistor R4 and a capacitor C are connected to the output terminal of the comparator 41a. When the voltage of the secondary battery 4 exceeds the reference voltage, the changeover switch SW is switched from the contact a to the contact b with the voltage charged to the capacitor C. The LED 43 connected to the contact b is caused to emit light.
[0052]
Note that the values of the resistors R2 and R3 are set so that the reference voltage becomes a voltage when the charging operation of the secondary battery 4 is completed.
Further, the changeover switch SW is constituted by, for example, an analog switch, and its power is supplied from the rectifier circuit 22a similarly to the comparator 41 (not shown in FIG. 7 for simplification). The other configuration is the same as that of the first embodiment.
[0053]
According to the present embodiment, in addition to having the same operation as that of the first embodiment, when the charging operation of the secondary battery 4 is completed when the battery is charged, the state is changed to the voltage of the secondary battery. When the voltage exceeds the reference voltage, the changeover switch SW is switched to prevent the charging current from flowing through the secondary battery 4 and the LED 43 is caused to emit light (light on).
[0054]
For this reason, the surgeon or the like can confirm that the surgical instrument 3E is in a state where the charging operation is completed by turning on the LED 43. Therefore, the surgeon may use a surgical tool whose LED 43 is lit, and in this case, it is possible to more reliably prevent the battery from running out during the surgery.
[0055]
In addition, it is possible to prevent the secondary battery 4 from being charged excessively (a secondary battery 4 can be prevented from being rapidly deteriorated by excessive charging), and the charger 2 is turned on. Even if it is left as it is, it is possible to prevent the secondary battery 4 from being excessively charged, and the usability is improved.
[0056]
Therefore, according to the present embodiment, in addition to the effects of the first embodiment, whether or not the secondary battery 4 is fully charged can be easily known by lighting (non-lighting) the LED 43. In addition, it is easy to handle, such as preventing overcharge and preventing the life of the secondary battery 4 from decreasing, and preventing the secondary battery 4 from shortening the life even when the charger 2 is turned on. There are effects such as.
[0057]
In this embodiment, detection means for detecting the charging completion state is provided, and when the charging completion state is detected, the LED 43 is lit to notify the user of the charging completion state. The LED 43 may be turned on, and the LED 43 may be turned off in the charging completion state to notify the charging and the charging completion state.
[0058]
In this case, in FIG. 7, the anode of the LED 43 may be connected to the contact a of the changeover switch SW together with the anode of the diode 22c. Alternatively, an LED indicating charging may be turned on during charging, and an LED 43 having a wavelength different from that of the LED may be turned on in a charging completion state to notify the charging and charging completion state.
[0059]
In this case, in FIG. 7, the LED 43 emits green light, and the cathode and anode of the LED emitting red light may be connected to the cathode of the LED 43 of FIG. 7 and the contact a of the changeover switch SW.
[0060]
(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIGS.
FIG. 8 shows a tray-type surgical system 51, which includes a charger 52, a cart 53 for installing the charger 52, a sterilization tray 54 installed on the charger 52, and the sterilization tray 54. And a battery-driven surgical tool 55 to be placed.
[0061]
In the sterilization tray 54, a battery-driven surgical instrument 55 and a normal surgical instrument 56 can be installed.
The cord 11 extends from the charger 52, and a plug 12 is provided at the tip thereof.
[0062]
The charger 52 has the same configuration as that of the first embodiment, and is provided with a power transmission circuit 16 as shown in FIG. 9, and the inside of the battery-driven surgical instrument 55 arranged on the upper side thereof. Energy is supplied to the power receiving unit 21 provided in the contactless manner. The energy received by the power receiving unit 21 is supplied to the secondary battery 4 via the rectification / control unit 22 to charge the secondary battery 4.
[0063]
In the case of the tray type as described above, since the degree of freedom of the direction of the surgical instrument 55 is large, a weight 57 is provided inside the battery-driven surgical instrument 55, and the direction between the power transmission circuit 16 and the power receiving unit 21 is provided. However, the orientation is appropriate so that energy can be transmitted efficiently. For example, when the power transmission circuit 16 and the power reception unit 21 are configured by coils, energy generated by the coil of the power transmission circuit 16 is efficiently generated by the coil of the power reception unit 21 so that the axial directions of both coils are parallel to each other. I try to get it well.
The present embodiment has the following effects.
According to the present embodiment, charging is reliably performed even if the treatment tool 55 of a free orientation is arranged in the large sterilization tray 54.
[0064]
In addition, when the charging operation of the secondary battery 4 is completed as in the second embodiment, the charging current is prevented from flowing through the secondary battery 4 and the LED 43 or the like is notified so as to be understood by the user. Means may be provided.
