Description

本発明は、超音波振動によって生体組織の切除あるいは凝固する処置に加え、高周波電流による処置を行える超音波切開凝固装置に関する。   The present invention relates to an ultrasonic incision and coagulation apparatus capable of performing a treatment with a high-frequency current in addition to a treatment for excising or coagulating a living tissue by ultrasonic vibration.

近年、体腔内に細長の挿入部を挿入することにより、体腔内臓器などを観察したり、必要に応じて内視鏡観察下で各種治療処置が行われている。   In recent years, by inserting an elongated insertion portion into a body cavity, various treatment treatments are performed under observation of an endoscopic body organ or the like, and endoscopic observation as necessary.

前記内視鏡観察下で治療処置を行う方法の一つとして生体組織を吸着あるいは把持し、この吸着あるいは把持している部材に超音波振動を加えて生体組織を切除あるいは凝固するなどの処置を行うものが知られている。   As one of the methods for performing the therapeutic treatment under the endoscopic observation, a treatment such as adsorbing or grasping the living tissue and applying ultrasonic vibration to the adsorbing or grasping member to excise or coagulate the living tissue. What to do is known.

例えば、特開昭62−127042号公報には結石を把持して超音波振動により破砕するようにした超音波砕石プローブが示されている。また、特開平1−232944号公報には生体組織を把持鉗子で把持固定し、超音波振動するプローブで切開するようにした外科用手術装置が示されている。さらに、特開平1−232945号公報には生体組織を吸着して固定し、超音波振動するメスにより切開するようにした外科用手術装置が示されている。又、特開平1−232948号公報には切除鉗子に超音波振動を加えることにより生体組織の切除を効率的に行えるようにした外科用切除鉗子が示されている。また更に、特開平1−232949号公報には前記特開平1−232944号公報と同様に把持手段により生体組織を固定し、超音波振動を加えた可動部材により生体組織に処置を加えるようした外科用手術装置が示されている。又、USP5322055号には超音波プローブに向かって回動自在な把持部材を設け、この超音波プローブと把持部材とで生体組織を把持して超音波振動を付加することによって生体組織を凝固したり切開したりできるようにした超音波外科器具のためのクランプ凝固装置及び切断システムが示されている。これら超音波を用いて処置を行う装置では通常の外科鉗子を使用するように生体組織を把持して処置が行えるので、プローブ単体で処置を行う場合よりも良好な処置を行うことができる。   For example, Japanese Patent Laid-Open No. 62-127042 discloses an ultrasonic lithotripsy probe that holds a calculus and is crushed by ultrasonic vibration. JP-A-1-232944 discloses a surgical operation apparatus in which a living tissue is grasped and fixed with grasping forceps and incised with a probe that vibrates ultrasonically. Further, JP-A-1-232945 discloses a surgical operation apparatus in which a living tissue is adsorbed and fixed and incised by a scalpel that is ultrasonically vibrated. Japanese Laid-Open Patent Publication No. 1-223248 discloses a surgical excision forceps that can efficiently excise a living tissue by applying ultrasonic vibration to the excision forceps. Furthermore, in JP-A-1-232949, a surgical procedure in which a living tissue is fixed by a gripping means and treatment is applied to the living tissue by a movable member to which ultrasonic vibration is applied, as in JP-A-1-232944. A surgical device is shown. Further, US Pat. No. 5322055 is provided with a gripping member that is rotatable toward the ultrasonic probe, and the biological tissue is coagulated by gripping the biological tissue with this ultrasonic probe and the gripping member and applying ultrasonic vibration. A clamp coagulation device and cutting system for an ultrasonic surgical instrument that is capable of incision is shown. With these devices that perform treatment using ultrasonic waves, treatment can be performed by grasping a living tissue so as to use normal surgical forceps, and therefore, a better treatment can be performed than when performing treatment with a single probe.

一方、高周波電流による処置が行えるものとしては特開平6−179049号公報に示すような内視鏡外科手術用処置具が一般的であり、その殆どがモノポーラと呼ばれる高周波電流を処置具から生体組織を通して体極板と呼ばれる帰還部に流して処置を行うタイプであった。このタイプの処置具は止血性能が優れていた。   On the other hand, a treatment instrument for endoscopic surgery as shown in Japanese Patent Application Laid-Open No. 6-179049 is generally used as a treatment that can be performed with a high-frequency current, and most of the treatment uses a high-frequency current called a monopolar from a treatment tool to a living tissue. It was the type which flows through the return part called the body electrode plate through the treatment. This type of treatment tool had excellent hemostatic performance.

これに対して特開平6−30947号公報に示されているバイポーラと呼ばれる処置具は、鉗子部の把持部材間に高周波電流の回路を組み込んだタイプであった。このタイプの処置具は、生体組織の不要な部分には高周波電流が流れないようになっており、鉗子部材を電気的に絶縁し、鉗子部材を駆動する伝達部材とシースとを絶縁する一方でそれぞれに給電手段が設けられていた。
特開昭62−127042号公報 特開平 1−232944号公報 特開平 1−232945号公報 特開平 1−232948号公報 特開平 1−232949号公報 米国特許第5322055号公報 特開平 6−179049号公報 特開平 6−30947号公報 特開平 3−111037号公報 特開平 5−3348号公報 米国特許第4931047号公報
On the other hand, the treatment tool called bipolar shown in JP-A-6-30947 is a type in which a high-frequency current circuit is incorporated between gripping members of the forceps. In this type of treatment tool, high-frequency current does not flow through unnecessary portions of living tissue, while electrically insulating the forceps member and insulating the transmission member that drives the forceps member and the sheath. Each was provided with power supply means.
Japanese Patent Laid-Open No. 62-127042 JP-A-1-232944 JP-A-1-232945 JP-A-1-232948 JP-A-1-232949 US Pat. No. 5,322,055 JP-A-6-179049 JP-A-6-30947 Japanese Patent Laid-Open No. 3-1111037 JP-A-5-3348 US Pat. No. 4,931,047

しかしながら、上述の特開昭62−127042号公報,特開平1−232944号公報や特開平1−232948号公報などに示されている超音波を用いて処置を行う装置では生体組織に対して超音波振動による処置しか行うことができなかった。一般に、超音波振動による処置は、高周波電流による処置に比べて止血能力が劣るため、緊急に止血したい場合などには超音波振動を用いる処置具から高周波電流を用いる処置具に交換しなければならず、使い勝手が悪かった。   However, in the apparatus for performing treatment using the ultrasonic waves shown in the above-mentioned JP-A-62-127042, JP-A-1-232944, JP-A-1-232948, etc. Only treatment by sonic vibration could be performed. In general, since treatment with ultrasonic vibration is inferior to hemostasis in comparison with treatment with high-frequency current, a treatment instrument that uses ultrasonic vibration must be replaced with a treatment instrument that uses high-frequency current when urgent hemostasis is desired. The usability was bad.

一方、高周波電流による処置が行える特開平6−179049号公報の内視鏡外科手術用処置具では生体組織の不要な部分に電流が流れるおそれがあるという問題の他に、上述の高周波電流を用いて処置を行う内視鏡用処置具では高周波電流による処置しか行うことができず、止血性能は良好であるが、生体組織に及ぼす影響が大きく、過度の焼灼を行うおそれがあった。   On the other hand, in the endoscopic surgical treatment tool disclosed in Japanese Patent Laid-Open No. 6-179049 capable of performing treatment with a high-frequency current, the above-described high-frequency current is used in addition to the problem that current may flow to an unnecessary part of a living tissue. Endoscopic treatment tools that can be treated in this way can only perform treatment with a high-frequency current and have good hemostatic performance, but have a large effect on living tissue and may cause excessive cauterization.

このため、実際に処置を行う術者にとっては、超音波振動による処置をできるだけ行い、必要な時にだけ高周波電流による処置を行えることが理想的であるが、内視鏡外科手術用処置具単体で超音波振動による処置を行い、必要な時だけ高周波電流による処置を行うことは不可能であった。   For this reason, it is ideal for an operator who actually performs treatment to perform treatment by ultrasonic vibration as much as possible, and to perform treatment by high-frequency current only when necessary. It was impossible to perform treatment with ultrasonic vibration and treatment with high-frequency current only when necessary.

そこで、これらの問題を解決するため、特開平3−111037号公報や、特開平5−23348号公報及びUSP4931047号には超音波振動と高周波電流による処置を併用できる超音波吸引器などと呼ばれる超音波処置装置が示されている。これらの装置では、棒状あるいはヘラ状に形成したプローブを生体組織に押し付けて処置するようになっていた。このため、前記プローブを確実に目的の生体組織を押さえて処置を行うことが難しく、細かい操作を行うためには他に複数の鉗子等で補助する必要があった。しかし、通常の開腹手術では問題とはならない操作でも、内視鏡下外科手術においては、複数の内視鏡下外科手術用処置具である鉗子を用いることは生体組織に多数の孔を開けることになるので、低侵襲という点で問題があった。さらに、モニターの画面上に表示される内視鏡画像を観察しながら遠隔操作を行って、複数の処置具と協調操作することが難かしく、簡単で、且つ、確実に処置のできる処置具が望まれていた。なお、前記USP5322055号のクランプ凝固装置及び切断システムはこの問題を解決するものであるが、前述したように高周波電流を用いる処置を併用することができないという問題があった。   Therefore, in order to solve these problems, Japanese Patent Application Laid-Open No. 3-1111037, Japanese Patent Application Laid-Open No. 5-23348 and US Pat. No. 4,923,047 include an ultrasonic aspirator that can be used with both ultrasonic vibration and high frequency current treatment. A sonication device is shown. In these devices, a probe formed in a rod shape or a spatula shape is pressed against a living tissue to perform treatment. For this reason, it is difficult to perform the treatment by reliably pressing the target living tissue with the probe, and it is necessary to assist with a plurality of forceps or the like in order to perform a fine operation. However, even in operations that are not a problem in normal laparotomy, in endoscopic surgery, using multiple forceps, which are treatment tools for endoscopic surgery, opens a large number of holes in living tissue. Therefore, there was a problem in terms of minimal invasiveness. Furthermore, there is a treatment tool that is difficult to operate in cooperation with a plurality of treatment tools by performing remote control while observing an endoscopic image displayed on the monitor screen, and that can be easily and reliably treated. It was desired. The clamp coagulation apparatus and cutting system of US Pat. No. 5,322,055 solves this problem, but there is a problem that it is impossible to use a treatment using a high-frequency current as described above.

The gripping member 6 is opened and closed with respect to the probe 5.

前記挿入部3は、電気絶縁性を有する例えば、ポリサルフォンやBEEK等の樹脂部材で形成された電気絶縁手段となるシース11であり、このシース11には前記プローブ5が挿通するプローブ挿通用管路12と、前記把持部材6に接続する伝達部材10が挿通する伝達部材用管路13とが電気的に完全に絶縁されて設けられている。   The insertion portion 3 is a sheath 11 serving as an electrical insulating means formed of a resin member such as polysulfone or BEEK having electrical insulation, and a probe insertion conduit through which the probe 5 is inserted. 12 and a transmission member pipe line 13 through which the transmission member 10 connected to the gripping member 6 is inserted are completely insulated.

図2及び図3に示すように前記伝達部材用管路13の先端側開口部には電気絶縁性を有する先端カバー14が嵌入固定されており、前記シース11と同様にポリサルフォンやBEEK等の樹脂材料あるいはセラミックなどで形成されている。この先端カバー14には前記把持部材6が第1のピン21によって回動自在に取り付けられている。   As shown in FIGS. 2 and 3, a distal end cover 14 having electrical insulation is fitted into and fixed to the distal end side opening of the transmission member conduit 13, and, like the sheath 11, a resin such as polysulfone or BEEK.

Further, the insertion portion 3 is connected and fixed to the upper portion of the fixed handle 4 a located on the distal end side of the operation portion 4. A movable handle 4b is pivotally supported on the fixed handle 4a by a third pin 23, and the rotation of the movable handle 4b is transmitted to the transmission member 10. The fixed handle 4a and the movable handle 4b are both made of an electrically insulating material such as polysulfone or BEEK.

前記伝達部材10の手元側端部には球状部24aを形成した係合部材24が固定されている。この球状部24aは、可動ハンドル4bの上方部に形成されている係合溝24に回動摺動自在に保持されている。この係合溝24には球状部24aに接触するように導電部材25が設けられており、この導電部材25に高周波電源からの高周波電流を把持部材6に給電するための第1高周波電流コード7が接続されている。また、前記超音波振動子16の後部からは前記プローブ5に高周波電流を給電するための第2高周波電流コード8及び超音波振動子16に駆動用電流を給電するための超音波振動子駆動用コード9が接続されている。   An engaging member 24 having a spherical portion 24 a is fixed to the proximal end of the transmission member 10. The spherical portion 24a is rotatably held in an engagement groove 24 formed in the upper portion of the movable handle 4b. The engaging groove 24 is provided with a conductive member 25 so as to be in contact with the spherical portion 24a, and a first high-frequency current cord 7 for feeding a high-frequency current from a high-frequency power source to the gripping member 6 to the conductive member 25.

For this reason, the probe 5 is completely isolated from other members between the probe insertion conduit 12 and the ultrasonic transducer housing 27.

さらに、前記超音波振動子ハウジング27の後方部は第2のパッキン32によって密閉され、前記第1高周波電流コード7の前方出口も第3のパッキン33によって密閉されている。   Further, the rear portion of the ultrasonic transducer housing 27 is sealed with a second packing 32, and the front outlet of the first high-frequency current cord 7 is also sealed with a third packing 33.

すなわち、超音波切開凝固装置1は、前記プローブ5及び超音波振動子16と、係合部材24,伝達部材10,先端カバー14及び把持部材6とがお互いに電気的に完全に絶縁されると共に、前記プローブ5及び超音波振動子16と、係合部材24,伝達部材10,先端カバー14及び把持部材6とは外部に対しても電気的に絶縁されている。   That is, in the ultrasonic incision and coagulation apparatus 1, the probe 5 and the ultrasonic transducer 16, the engagement member 24, the transmission member 10, the tip cover 14, and the gripping member 6 are completely electrically insulated from each other. The probe 5 and the ultrasonic transducer 16, the engaging member 24, the transmission member 10, the tip cover 14, and the gripping member 6 are electrically insulated from the outside.

図6に示すように超音波切開凝固装置1において、処置部2を構成する把持部材6は、伝達部材10、係合部材24、導電部材25、第1高周波電流コード7、把持部材用高周波電流コネクタ7aを経て高周波電源28に接続されている。一方、処置部2を構成するプローブ5は、超音波振動子16、第2高周波電流コード8、プローブ用高周波電流コネクタ8aを経て高周波電源28に接続されている。さらに、超音波振動子16は、超音波振動子駆動用コード9、超音波振動子駆動用コネクタ9aを経て超音波振動子駆動電源29に接続されている。   As shown in FIG. 6, in the ultrasonic incision and coagulation apparatus 1, the gripping member 6 constituting the treatment unit 2 includes a transmission member 10, an engagement member 24, a conductive member 25, a first high frequency current cord 7, and a gripping member high frequency current. It is connected to the high frequency power supply 28 via the connector 7a. On the other hand, the probe 5 constituting the treatment section 2 is connected to the high frequency power supply 28 via the ultrasonic transducer 16, the second high frequency current cord 8, and the probe high frequency current connector 8a. Further, the ultrasonic transducer 16 is connected to the ultrasonic transducer driving power source 29 via the ultrasonic transducer driving cord 9 and the ultrasonic transducer driving connector 9a.

又、体極板30が高周波電源28の帰還部側に接続されている。このように把持部材6とプローブ5とは電気的に完全に絶縁されている。   The body electrode plate 30 is connected to the feedback portion side of the high frequency power supply 28. Thus, the gripping member 6 and the probe 5 are electrically completely insulated.

上述のように構成されている超音波切開凝固装置1の作用を説明する。
まず、超音波切開凝固装置1を生体内の目的の生体組織に対向させる。そして、操作部4の可動ハンドル4bを開状態になるように操作して把持部材6をプローブ5に対して開放させる。
The operation of the ultrasonic incision and coagulation apparatus 1 configured as described above will be described.
First, the ultrasonic incision and coagulation apparatus 1 is opposed to a target living tissue in the living body. Then, the gripping member 6 is opened with respect to the probe 5 by operating the movable handle 4 b of the operation unit 4 to be in an open state.

次に、目的の生体組織を把持部材6とプローブ5と間に挟みこむために前記可動ハンドル4bを閉状態になるように操作して把持部材6をプローブ5に対して閉鎖させることによって生体組織を把持する。   Next, in order to sandwich the target biological tissue between the grasping member 6 and the probe 5, the movable handle 4 b is operated to be closed to close the grasping member 6 with respect to the probe 5. Hold it.

次いで、この状態で、超音波振動子駆動電源29から超音波振動子駆動用電流を超音波振動子16に給電して超音波振動子16を駆動する。すると、超音波振動子16が振動することによってプローブ5に超音波振動が伝達され、この超音波振動を生体組織に与えて、生体組織の切開あるいは凝固を行う。   Next, in this state, the ultrasonic transducer driving power source 29 supplies the ultrasonic transducer driving current to the ultrasonic transducer 16 to drive the ultrasonic transducer 16. Then, the ultrasonic vibration 16 is vibrated to transmit the ultrasonic vibration to the probe 5, and this ultrasonic vibration is applied to the living tissue to incise or coagulate the living tissue.

一方、高周波電流を用いる処置を行う場合は、把持部材6とプローブ5との間に生体組織を把持して把持部材6あるいはプローブ5のどちらかまたは把持部材6及びプローブ5の両方に高周波電源28から高周波電流を給電する。このとき、把持部材6、プローブ5から体極板30へ図6の破線に示すように生体組織を通して高周波電流を流し、高周波電源28に帰還させることにより、生体組織の切開あるいは凝固を行う。   On the other hand, when a treatment using a high-frequency current is performed, a living tissue is grasped between the grasping member 6 and the probe 5 and either the grasping member 6 or the probe 5 or both the grasping member 6 and the probe 5 are provided with the high-frequency power source 28. High frequency current is supplied from At this time, as shown by the broken line in FIG. 6 from the grasping member 6 and the probe 5 to the body electrode plate 30, a high-frequency current is passed through the living tissue and returned to the high-frequency power source 28, thereby cutting or coagulating the living tissue.

なお、生体組織を把持部材6とプローブ5との間に把持せずにプローブ5を生体組織に押し付けて超音波振動を与えて処置を行うようにしても良い。また、体極板30を使用することなく、生体組織を把持部材6とプローブ5とによって把持し、前記把持部材6とプローブ5との間に高周波電流を流して処置を行うようにしても良い。さらに、生体組織を把持せずに把持部材6とプローブ5とで剥離する様にしても良いし、どちらかを押し当てて処置を行うようにしても良い。   Note that the treatment may be performed by pressing the probe 5 against the living tissue and applying ultrasonic vibration without holding the living tissue between the grasping member 6 and the probe 5. Further, without using the body electrode plate 30, the living tissue may be grasped by the grasping member 6 and the probe 5, and the treatment may be performed by flowing a high-frequency current between the grasping member 6 and the probe 5. . Further, the grasping member 6 and the probe 5 may be separated without grasping the living tissue, or one of them may be pressed to perform the treatment.

このように、把持部材とプローブとが電気的に完全に絶縁されているので、高周波電流による処置を行う際、高周波電流の漏れがなく、処置を安全に行うことができる。   As described above, since the gripping member and the probe are electrically completely insulated, there is no leakage of the high frequency current when performing the treatment with the high frequency current, and the treatment can be performed safely.

また、超音波振動による処置と高周波電流による処置を同時に行うことが可能であるので、超音波振動による処置をできるだけ行い、必要な時にだけ高周波電流による処置を行って、良好な止血性能と、過度の組織変性防止の双方の効果を得ることができる。   In addition, since treatment with ultrasonic vibration and treatment with high-frequency current can be performed at the same time, treatment with ultrasonic vibration is performed as much as possible, and treatment with high-frequency current is performed only when necessary. Both effects of preventing tissue degeneration can be obtained.

さらに、高周波電流を流して処置を行う場合、体極板を使用して生体組織に高周波電流を通して処置を行ったり、体極板を使用せずに生体組織を把持部材とプローブとの間に把持して把持部材とプローブとの間の生体組織に高周波電流を通して処置するなど術者の選択の幅が広がる。   Furthermore, when treatment is performed by applying a high-frequency current, treatment is performed through the high-frequency current to the living tissue using a body electrode plate, or the living tissue is grasped between the grasping member and the probe without using the body electrode plate. Thus, the operator has a wider range of choice, such as treating the living tissue between the grasping member and the probe through high-frequency current.
