−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。 The -232944 discloses a biological tissue gripped fixed with grasping forceps, and surgical operation apparatus adapted to incision with a probe of the ultrasonic vibration is shown. さらに、特開平1−23 In addition, JP-A-1-23
2945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。 The 2945 JP fixed by adsorbing biological tissue, and surgical operation apparatus adapted to the incision by scalpel to the ultrasonic vibration is shown. 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。 Further, Japanese Patent Laid-Open No. 1-232948 has been shown surgical resection forceps to allow the resection of body tissue efficiently by applying ultrasonic vibration to the resection forceps. 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。 Furthermore, the biological tissue is fixed by the same gripping means and JP-A Hei 1-232944 to JP-A-1-232949, surgery and to apply a treatment to a living tissue by the movable member applying ultrasonic vibrations use surgical apparatus is shown. 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。 Further, the Patent USP5322055 provided rotatable gripping member toward the ultrasonic probe, or to coagulate the living tissue by adding the grasped ultrasonic vibrations to the living tissue between the ultrasonic probe and the grasping member clamp coagulator apparatus and cutting system for an ultrasonic surgical instrument to allow or incision is shown. 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。 Since the treatment can be performed by gripping the body tissue to use a regular forceps in apparatus for performing treatment using these ultrasonic, it can be performed better treatment than the case of performing the treatment with the probe alone.

【0005】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。 On the other hand, as can be performed treatment with high-frequency current is common endoscopic surgical treatment tool as shown in JP-A-6-179049, a treatment instrument a high frequency current most of called monopolar from a type of performing treatment by flowing a feedback portion called the body electrode plate through biological tissue. このタイプの処置具は止血性能が優れていた。 This type of treatment instrument had excellent hemostatic performance.

【0007】 [0007]

【発明が解決しようとする課題】しかしながら、上述の特開昭62−127042号公報,特開平1−2329 However [0007], above JP 62-127042, JP Hei 1-2329
44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。 In apparatus for performing treatment using ultrasound indicated like 44 and JP 1-232948 discloses could not only carry out the treatment by the ultrasonic vibration to the living tissue. 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。 In general, treatment with ultrasonic vibrations, since the hemostatic ability is inferior to the treatment with high-frequency current, is when you want to urgently hemostasis to be replaced to the treatment instrument using a high-frequency current from a treatment instrument using ultrasonic vibration not, usability is poor.

【0008】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 addition to the problem of the endoscopic surgical treatment instrument of JP-A-6-179049 discloses that allows the treatment with high-frequency current is likely to flow a current to the unnecessary portion of the living tissue, the above-mentioned high-frequency the endoscopic treatment instrument that performs treatment using a current can be performed only treatment with the high-frequency current, but hemostasis performance is good, a large impact on the biological tissue, there is a risk that undue ablation .

【0009】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。 [0009] Therefore, for the surgeon to perform the actual treatment is performed as much as possible the treatment by ultrasonic vibration, only when needed, but it can perform treatment with high-frequency current is ideal treatment for endoscopic surgery in tool itself performs treatment by ultrasonic vibration, it was to perform the treatment with only when needed frequency current impossible.

【0010】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 [0010] In order to solve these problems, and JP-A-3-111037, JP-A-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。 No. The publications and Patent USP4931047 are shown ultrasonic treatment apparatus called ultrasonic aspirator which can be used in combination treatment with ultrasonic vibration and high-frequency current. 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。 In these devices, a probe formed into a rod or paddle was supposed to treat against the body tissue. 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。 Therefore, the reliable difficult to perform treatment by pressing the desired living tissue probes, in order to perform a fine operation had to be assisted by a plurality of forceps in the other. 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。 However, even in an operation not be a problem in normal open surgery, in the endoscopic surgical operation, the use of forceps which are a plurality of endoscopic surgical treatment instrument to open a number of holes in a biological tissue . therefore, there has been a problem in terms of minimally invasive. 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。 Further, by performing the remote operation while observing an endoscope image displayed on the monitor screen, it is hardly Kashiku cooperating operation with a plurality of treatment instruments, simple, and, the treatment instrument that can reliably treatment was desired is in. 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。 Incidentally, clamp coagulator apparatus and cutting system of the No. USP5322055 is solves this problem, there is a problem that can not be used in combination treatment with a high-frequency current as described above.

【0011】本発明は上記事情に鑑みてなされたものであり、生体組織に超音波振動による処置と高周波電流による処置とを適切に、且つ、容易に行える超音波処置具を提供することを目的としている。 [0011] The present invention has been made in view of the above circumstances, an object properly and treated with the treatment and the high-frequency current by the ultrasonic vibrations to a living tissue, and, to provide an ultrasonic treatment apparatus which facilitates It is set to.

【0012】 [0012]

【課題を解決するための手段】本発明の超音波切開凝固装置は、生体組織に超音波振動子からの超音波振動を与えるプローブ及びこのプローブに対向して回動自在な把持部材で構成した処置部と、この処置部を生体内に挿入する挿入部と、前記処置部の把持部材をプローブに対して開閉操作する操作部と、この操作部の操作力を前記把持部材に伝達する伝達部材とを備えた超音波切開凝固装置であって、前記伝達部材と前記プローブとを互いに電気的に絶縁すると共に、前記伝達部材及びプローブをそれぞれ外部に対して電気的に絶縁する電気絶縁手段を具備している。 Ultrasonic dissection coagulation apparatus of the present invention, in order to solve the problem] was composed of rotatable gripping member in opposition to the probe and this probe to ultrasonic vibration from the ultrasonic transducer to the biological tissue a treatment portion, an insertion portion for inserting the treatment portion in a living body, an operation portion for opening and closing the gripping member of the treatment portion to the probe, transmitting member for transmitting the operating force of the operation portion to the gripping member an ultrasonic dissection coagulation apparatus equipped with bets, wherein with the transmission member and the the electrically insulated from each other said probe, comprising an electrically insulating means for electrically isolating the transmitting member and the probe to the outside, respectively doing.
