The foot switch 4 operated with a foot may be replaced with a switch operated with a hand or other switches. When the operator operates the pedal of the foot switch 4, ON / OFF of the supply of energy from the control device 3 to the pair of high-frequency electrodes 16a, 16b of the energy treatment device 2 is switched.

スライドレバー１７は、ハンドル５にシース６の軸方向に沿って形成されたガイド溝１８に沿ってシース６の軸方向に移動可能に設けられている。このスライドレバー１７には、スリーブ１５の基端部側および一対の高周波電極１６ａ、１６ｂの基端部側が連結されている。そして、スライドレバー１７をガイド溝１８に沿ってスライド操作することによりスリーブ１５と一対の高周波電極１６ａ、１６ｂとが一緒に軸方向にスライド操作されるようになっている。   The slide lever 17 is provided so as to be movable in the axial direction of the sheath 6 along a guide groove 18 formed in the handle 5 along the axial direction of the sheath 6. The slide lever 17 is connected to the base end side of the sleeve 15 and the base end side of the pair of high-frequency electrodes 16a and 16b. By sliding the slide lever 17 along the guide groove 18, the sleeve 15 and the pair of high-frequency electrodes 16a and 16b are slid together in the axial direction.

また、図６または図８（Ａ）の断面形状に示すようにスリーブ１５の先端部の両側面には、バルーン用開口部１９ａ、１９ｂが形成されている。これらのバルーン用開口部１９ａ、１９ｂには、図７の断面形状に示すように膨張／縮小変形可能なバルーン（切断面移動部）２０ａ、２０ｂが縮小された状態で組み込まれている。   Further, as shown in the cross-sectional shape of FIG. 6 or FIG. 8A, balloon openings 19a and 19b are formed on both side surfaces of the distal end portion of the sleeve 15. In these balloon openings 19a and 19b, balloons (cutting surface moving portions) 20a and 20b that can be inflated / reduced and deformed are incorporated in a reduced state as shown in the cross-sectional shape of FIG.

スリーブ１５の基端部には、図３に示すように空気や、生理食塩水などの作動流体を供給する作動流体供給部２１が連結されている。この作動流体供給部２１は、ハンドル５の操作ボタン２２によってオンオフ操作されるようになっている。そして、操作ボタン２２のオン操作時には、スリーブ１５の内部管路を介してバルーン用開口部１９ａ、１９ｂからバルーン２０ａ、２０ｂ内に空気や、生理食塩水などの作動流体が供給されることにより、バルーン２０ａ、２０ｂが膨張するようになっている（図８（Ｂ）参照）。   As shown in FIG. 3, a working fluid supply unit 21 that supplies working fluid such as air or physiological saline is connected to the base end of the sleeve 15. The working fluid supply unit 21 is turned on and off by an operation button 22 of the handle 5. When the operation button 22 is turned on, air or a working fluid such as physiological saline is supplied from the balloon openings 19a and 19b into the balloons 20a and 20b through the internal conduits of the sleeve 15. The balloons 20a and 20b are inflated (see FIG. 8B).

また、本実施の形態のエネルギー処置装置２では、生体組織Ｈの切断面Ｈｃの封鎖を行う封鎖手段２４が設けられている。この封鎖手段２４は、カッター部７で血管などの生体組織Ｈを切断したのち、高周波エネルギーを印加して生体組織Ｈの切断面Ｈｃ同士を吻合させるものである。すなわち、封鎖手段２４は、例えばカッター部７と高周波電極１６ａ、１６ｂで構成される。カッター部７で血管及び脈管組織などの生体組織Ｈを切断した際には、この生体組織Ｈの露出した切断面Ｈｃに生体組織の細胞外基質であるコラーゲン及びエラスチンなどの組織吻合に必要なタンパク質が滲み出てくる（以降、この滲み出させることを抽出と呼ぶ）。この状態で、スライドレバー１７をガイド溝１８に沿ってスライド操作することによりスリーブ１５と一対の高周波電極１６ａ、１６ｂとを一緒に軸方向にスライド操作させる。これにより、図６の断面形状に示すように上カッター８ａのスリーブガイド溝８ａ３と下カッター８ｂのスリーブガイド溝８ｂ３との間の円形状ガイド溝にスリーブ１５が挿入されるとともに、生体組織Ｈの切断面Ｈｃの片側に一方の高周波電極１６ａ、生体組織Ｈの切断面Ｈｃの他方の片側に他方の高周波電極１６ｂがそれぞれ血管、もしくは脈管組織の側部から挿入される。   Moreover, in the energy treatment apparatus 2 of this Embodiment, the sealing means 24 which seals the cut surface Hc of the biological tissue H is provided. This sealing means 24 cuts the living tissue H such as a blood vessel by the cutter unit 7 and then applies high frequency energy to anastomoses the cut surfaces Hc of the living tissue H. That is, the sealing means 24 is comprised by the cutter part 7 and the high frequency electrodes 16a and 16b, for example. When the biological tissue H such as blood vessels and vascular tissues is cut by the cutter unit 7, it is necessary for tissue anastomoses such as collagen and elastin which are extracellular substrates of the biological tissue on the exposed cut surface Hc of the biological tissue H. Protein exudes (hereinafter, this exudation is called extraction). In this state, the slide lever 17 is slid along the guide groove 18 to slide the sleeve 15 and the pair of high frequency electrodes 16a and 16b together in the axial direction. Thereby, as shown in the cross-sectional shape of FIG. 6, the sleeve 15 is inserted into the circular guide groove between the sleeve guide groove 8a3 of the upper cutter 8a and the sleeve guide groove 8b3 of the lower cutter 8b, and the living tissue H One high-frequency electrode 16a is inserted into one side of the cut surface Hc, and the other high-frequency electrode 16b is inserted into the other side of the cut surface Hc of the living tissue H from the side of the blood vessel or vascular tissue.

この状態で、高周波電極１６ａ、１６ｂを動作させて生体組織Ｈの切断面Ｈｃに高周波エネルギーを印加して吻合させ、生体組織Ｈの切断面Ｈｃの封鎖を行なうようになっている。このとき、操作ボタン２２がオン操作され、スリーブ１５の内部管路を介してバルーン用開口部１９ａ、１９ｂからバルーン２０ａ、２０ｂ内に空気や、生理食塩水などの作動流体が供給される。これにより、図８（Ｂ）の断面形状に示すようにバルーン２０ａ、２０ｂが膨張することで、生体組織Ｈの切断面Ｈｃの端縁部が内側に折り返されるようになっている。そのため、生体組織Ｈの切断面Ｈｃ同士を内側に折り返す（内側に捲る）ことで接合面積を大きくすることができる。   In this state, the high-frequency electrodes 16a and 16b are operated to apply high-frequency energy to the cut surface Hc of the living tissue H to cause anastomosis, thereby sealing the cut surface Hc of the living tissue H. At this time, the operation button 22 is turned on, and working fluid such as air and physiological saline is supplied from the balloon openings 19a and 19b into the balloons 20a and 20b via the internal conduits of the sleeve 15. Thereby, as shown in the cross-sectional shape of FIG. 8B, the balloons 20a and 20b are inflated so that the edge of the cut surface Hc of the living tissue H is folded back inward. Therefore, the joining area can be increased by folding the cut surfaces Hc of the living tissue H inward (turning inward).

（作用）
次に、上記構成の本実施の形態のエネルギー処置装置２の作用について説明する。本実施の形態のエネルギー処置装置２の使用時には、エネルギー処置装置２のカッター部７及びシース６は、例えば、腹壁を通して腹腔内に挿入される。術者は、操作レバー１０を操作してカッター部７の下カッター８ｂと上カッター８ａとを開閉駆動させる。このとき、下カッター８ｂと上カッター８ａとを閉じる操作によって図５の断面形状に示すように処置対象の生体組織Ｈを押し潰す状態で把持する。これにより、処置対象の生体組織Ｈである血管、もしくは脈管組織の管内部に挿入されている血液などの内蔵物が生体組織Ｈの押し潰した管内部分から押し出される。 (Function)
Next, the operation of the energy treatment device 2 of the present embodiment having the above configuration will be described. When the energy treatment device 2 of the present embodiment is used, the cutter unit 7 and the sheath 6 of the energy treatment device 2 are inserted into the abdominal cavity through the abdominal wall, for example. The surgeon operates the operation lever 10 to open and close the lower cutter 8b and the upper cutter 8a of the cutter unit 7. At this time, as shown in the cross-sectional shape of FIG. 5 by the operation of closing the lower cutter 8b and the upper cutter 8a, the biological tissue H to be treated is gripped in a crushed state. Thereby, a built-in object such as a blood vessel, which is a living tissue H to be treated, or blood inserted into a tube of the vascular tissue is pushed out from the crushed inner portion of the living tissue H.

このようにカッター部７の下カッター８ｂと上カッター８ａとによって処置対象の生体組織Ｈを押し潰す状態で把持した後、さらに強い力で下カッター８ｂと上カッター８ａとを閉じる操作を行う。これにより、図６に示すように生体組織Ｈの押し潰した部分が下カッター８ｂの切り刃８ｂ２と上カッター８ａの切り刃８ａ２とによって切断される。このとき、生体組織Ｈの切断面Ｈｃには生体組織の細胞外基質である吻合組織界面のコラーゲン及びエラスチンなどの吻合組織内の分子的な絡み合いに必要な組織成分が強制的に抽出される。   After gripping the treatment target biological tissue H in a state of being crushed by the lower cutter 8b and the upper cutter 8a in this manner, the operation of closing the lower cutter 8b and the upper cutter 8a with a stronger force is performed. Thereby, as shown in FIG. 6, the crushed portion of the living tissue H is cut by the cutting blade 8b2 of the lower cutter 8b and the cutting blade 8a2 of the upper cutter 8a. At this time, tissue components necessary for molecular entanglement in the anastomotic tissue such as collagen and elastin at the interface of the anastomotic tissue, which is an extracellular matrix of the biological tissue, are forcibly extracted from the cut surface Hc of the biological tissue H.

その後、スライドレバー１７をガイド溝１８に沿ってスライド操作することによりスリーブ１５と一対の高周波電極１６ａ、１６ｂとが一緒に軸方向にスライド操作される。このとき、接合される上カッター８ａのスリーブガイド溝８ａ３と下カッター８ｂのスリーブガイド溝８ｂ３との間に円形状ガイド溝に沿ってスリーブ１５が前進し、図８（Ａ）の断面形状に示すように、生体組織Ｈの切断面Ｈｃにスリーブ１５の先端部のバルーン２０ａ、２０ｂが配置される。これと同時に、一対の高周波電極１６ａ、１６ｂが、生体組織Ｈの切断面Ｈｃの両側に血管、もしくは脈管組織の側部から挿入される。   Thereafter, by sliding the slide lever 17 along the guide groove 18, the sleeve 15 and the pair of high frequency electrodes 16a and 16b are slid together in the axial direction. At this time, the sleeve 15 advances along the circular guide groove between the sleeve guide groove 8a3 of the upper cutter 8a to be joined and the sleeve guide groove 8b3 of the lower cutter 8b, and is shown in the cross-sectional shape of FIG. As described above, the balloons 20a and 20b at the tip of the sleeve 15 are arranged on the cut surface Hc of the living tissue H. At the same time, the pair of high-frequency electrodes 16a and 16b are inserted from both sides of the cut surface Hc of the living tissue H from the side of the blood vessel or vascular tissue.

この状態で、フットスイッチ４を操作するとともに、操作ボタン２２をオン操作する。フットスイッチ４がＯＮに切り換えられると、制御装置３から、ケーブル１１を介して高周波電極１６ａ、１６ｂに電力が通電される。これにより、高周波電極１６ａ、１６ｂによって生体組織Ｈの切断面Ｈｃに高周波エネルギーを印加させることにより、生体組織Ｈの切断面Ｈｃを加熱し、蛋白変性させて吻合させることができる。   In this state, the foot switch 4 is operated and the operation button 22 is turned on. When the foot switch 4 is switched to ON, power is supplied from the control device 3 to the high-frequency electrodes 16a and 16b via the cable 11. Thus, by applying high-frequency energy to the cut surface Hc of the living tissue H by the high-frequency electrodes 16a and 16b, the cut surface Hc of the living tissue H can be heated, protein-denatured, and anastomosed.

このとき、操作ボタン２２のオン操作により、スリーブ１５の内部管路を介してバルーン用開口部１９ａ、１９ｂからバルーン２０ａ、２０ｂ内に空気や、生理食塩水などの作動流体が供給される。これにより、図８（Ｂ）に示すようにバルーン２０ａ、２０ｂが膨張することで、生体組織Ｈの切断面Ｈｃの端縁部が内側に折り返される。そのため、生体組織Ｈの切断面Ｈｃの接合面積を大きくすることができるので、生体組織Ｈの切断面Ｈｃの接合力を増大することができる。   At this time, when the operation button 22 is turned on, air or a working fluid such as physiological saline is supplied from the balloon openings 19a and 19b into the balloons 20a and 20b via the internal conduits of the sleeve 15. As a result, as shown in FIG. 8B, the balloons 20a and 20b are inflated, whereby the end edge portion of the cut surface Hc of the living tissue H is folded inward. Therefore, since the joining area of the cut surface Hc of the living tissue H can be increased, the joining force of the cutting surface Hc of the living tissue H can be increased.

（効果）
本実施の形態のエネルギー処置装置２では、生体組織Ｈを切断するカッター部７と、生体組織Ｈに電気的および／または物理的エネルギー、例えば高周波エネルギーを印加させる一対の高周波電極１６ａ、１６ｂと、少なくともカッター部７で生体組織Ｈを切断して生体組織Ｈの切断面Ｈｃに生体組織の細胞外基質を抽出させた状態で、一対の高周波電極１６ａ、１６ｂを動作させて生体組織Ｈの切断面Ｈｃに高周波エネルギーを印加して吻合させ、生体組織Ｈの切断面Ｈｃの封鎖を行う封鎖手段２４とを設けている。そのため、封鎖手段２４によって生体組織Ｈの封鎖・吻合を簡単・確実に行うことができるエネルギー処置装置を提供することができる。 (effect)
In the energy treatment device 2 of the present embodiment, the cutter unit 7 that cuts the living tissue H, a pair of high-frequency electrodes 16a and 16b that apply electrical and / or physical energy, for example, high-frequency energy, to the living tissue H, At least in a state where the biological tissue H is cut by the cutter unit 7 and the extracellular matrix of the biological tissue is extracted from the cut surface Hc of the biological tissue H, the pair of high-frequency electrodes 16a and 16b are operated to cut the biological tissue H cut surface. There is provided sealing means 24 for applying high-frequency energy to Hc to cause anastomosis and sealing the cut surface Hc of the living tissue H. Therefore, it is possible to provide an energy treatment device capable of easily and reliably sealing and anastomosing the living tissue H by the sealing means 24.

また、本実施の形態のエネルギー処置装置２では生体組織Ｈの切断面Ｈｃの吻合前もしくは生体組織Ｈの切断面Ｈｃの吻合の初期段階で生体組織Ｈを切断することにより、生体組織Ｈの切断面Ｈｃの吻合組織界面のコラーゲン及びエラスチンなどの吻合組織内の分子的な絡み合いに必要な組織成分が強制的に抽出される。そのため、生体組織Ｈの切断面Ｈｃの吻合に必要な一対の高周波電極１６ａ、１６ｂによる高周波エネルギーの印加量を低減することができ、エネルギー印加による生体組織Ｈの熱的変性を最小限に抑えることができる。
また、高周波エネルギーの印加による生体組織の封鎖・吻合した後、カッターなどにより切断するエネルギー処置装置が検討されているが、その場合、封鎖・吻合に必要な細胞外基質の抽出が不十分な場合、強固な封鎖・吻合を行えない可能性がある。しかし、本実施の形態のエネルギー処置装置では、吻合初期段階で生体組織を切断するため、切断部の細胞外基質が吻合面に十分に抽出され、吻合組織内での分子的な絡み合いを実現でき、強固な封鎖・吻合を行うことができる。 Further, in the energy treatment device 2 of the present embodiment, the biological tissue H is cut by cutting the biological tissue H before the anastomosis of the cut surface Hc of the biological tissue H or at the initial stage of the anastomosis of the cut surface Hc of the biological tissue H. Tissue components necessary for molecular entanglement in the anastomotic tissue such as collagen and elastin at the anastomotic tissue interface of the surface Hc are forcibly extracted. Therefore, the amount of high frequency energy applied by the pair of high frequency electrodes 16a and 16b necessary for anastomosis of the cut surface Hc of the living tissue H can be reduced, and thermal denaturation of the living tissue H due to energy application can be minimized. Can do.
In addition, an energy treatment device that is sealed and anastomosed by applying high-frequency energy and then cut with a cutter or the like is being studied, but in that case, extraction of the extracellular matrix necessary for sealing or anastomosis is insufficient There is a possibility that a strong blockade / anastomosis cannot be performed. However, in the energy treatment device of the present embodiment, the biological tissue is cut at the initial stage of anastomosis, so that the extracellular matrix of the cut portion is sufficiently extracted on the anastomosis surface, and molecular entanglement within the anastomosis tissue can be realized. Can perform strong blockage and anastomosis.

さらに、一対の高周波電極１６ａ、１６ｂを生体組織Ｈの血管もしくは脈管組織の側部から挿入する際に、生体組織Ｈを傷つけることになるが、生体組織Ｈから一対の高周波電極１６ａ、１６ｂを除去した後、この傷痕部分を一対の高周波電極１６ａ、１６ｂによりエネルギー吻合することができる。   Further, when the pair of high-frequency electrodes 16a and 16b are inserted from the side of the blood vessel or vascular tissue of the living tissue H, the living tissue H is damaged. After removal, this scar can be anastomosed with a pair of high-frequency electrodes 16a and 16b.

また、生体組織Ｈの切断面Ｈｃに高周波エネルギーを印加させる際に、図８（Ｂ）に示すようにバルーン２０ａ、２０ｂを膨張させることで、生体組織Ｈの切断面Ｈｃの端縁部を内側に折り返すことができる。そのため、生体組織Ｈの切断面Ｈｃの接合面積を大きくすることができるので、生体組織Ｈの切断面Ｈｃの接合力を増大することができる。   Further, when high frequency energy is applied to the cut surface Hc of the living tissue H, the balloons 20a and 20b are inflated as shown in FIG. Can be folded. Therefore, since the joining area of the cut surface Hc of the living tissue H can be increased, the joining force of the cutting surface Hc of the living tissue H can be increased.

なお、本実施の形態では、生体組織Ｈの切断面Ｈｃを一対の高周波電極１６ａ、１６ｂによる高周波加熱によって吻合させ、生体組織Ｈの切断面Ｈｃの封鎖を行う構成を示したが、一対の高周波電極１６ａ、１６ｂに変えてヒータ加熱、もしくは超音波などのエネルギーを単独もしくは複合して印加することも効果的である。   In the present embodiment, the configuration in which the cut surface Hc of the living tissue H is anastomosed by high-frequency heating by the pair of high-frequency electrodes 16a and 16b and the cut surface Hc of the living tissue H is sealed is shown. It is also effective to apply heater heating or energy such as ultrasonic waves alone or in combination instead of the electrodes 16a and 16b.
