Description

【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、生体腔内の組織を超音波振動で切除して処
置する組織切除装置の改善に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement in a tissue resection device for ablating and treating tissue within a body cavity using ultrasonic vibrations.

【従来の技術〕[Conventional technology]

従来より、経尿道的な前立腺の切除術には、患部組織を
高周波電流で焼灼して切除することが行なわれている。Conventionally, in transurethral resection of the prostate, the affected tissue is cauterized and removed using high-frequency current.

しかし、こうした切除は焼灼した生体組織が変性白化す
るために、切除範囲の判別が困難で正常組織まで切除し
てしまう危険をもつ。しかも、誤って筋組織に電極が触
れてしまうと、患部が反射動作を起こして穿孔等を引起
こし出血多量が起こるおそれがあった。However, since such resection causes degeneration and whitening of the cauterized living tissue, it is difficult to determine the extent of resection, and there is a risk that normal tissue may also be resected. Moreover, if the electrode accidentally touches muscle tissue, there is a risk that the affected area will cause a reflex action, resulting in perforation or the like, resulting in profuse bleeding.

そこで、最近、超音波振動を使った組織切除装置で切除
することが行なわれるようになってきた。Therefore, recently, tissue resection devices using ultrasonic vibrations have been used to perform resection.

これには特願昭６０−１２０１号に示されるように、生
体内に挿入可能な挿入部の基部に超音波振動子をホーン
介して連結した構造が用いられる。For this purpose, as shown in Japanese Patent Application No. 1201/1983, a structure is used in which an ultrasonic transducer is connected via a horn to the base of an insertion section that can be inserted into a living body.

そして、前立腺に挿入部の先端の押し当てて、その組織
に超音波振動を与えることにより切除するようにしてい
る。Then, the tip of the insertion section is pressed against the prostate and the tissue is subjected to ultrasonic vibrations to be resected.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

ところが、こうした切除は、確かに生体組織の変性白化
がなく切除範囲の判別が容易となる。穿孔等が発生しな
い（いずれも高周波電流が流れないため）ものの、組織
の切除時、前立腺自体の血管を切除して出血をきたして
しまう難点があった。。However, in this type of resection, there is no degeneration or whitening of living tissue, and the range of resection can be easily determined. Although no perforation or the like occurs (because no high-frequency current flows in either case), when the tissue is removed, blood vessels in the prostate itself are removed, causing bleeding. .

この発明はこのような問題点に着目してなされたもので

After the living tissue is necrotized with microwaves to stop bleeding, the necrotic tissue is excised with an ultrasonic ablation device 7.

送水コック８は上記吸引用の通路４ａと連通している。The present invention will be explained below based on a first embodiment shown in FIGS. 1 and 2. In Figure 1, 1 is a gripping part, 2 is an ultrasonic transducer built into the gripping part 1, 3 is a conical horn placed on the tip side of the gripping part 1, and the horn 3 and the ultrasonic transducer 2 are is connected to. A transmission tube 4 having a diameter that can be inserted into a living body is connected to the tip of the horn 3, so that the ultrasonic vibrations generated by the ultrasonic vibrator 2 can be transmitted to the transmission tube 4. Although not shown, a hole is provided in the center of the gripping portion 1, coaxially communicating with the transmission tube 4, and together with the lumen, constitutes a suction passage 4a. Then, at the end of this passage 4a on the gripping part 1 side,
A suction pump (not shown) is a suction body5. It is connected via a suction tube 6, and the resected living tissue can be suctioned from a suction hole at the tip of the transmission tube 4. With such a structure, the ultrasonic ablation device 7 is configured, and at the same time, the transmission tube 4 is used as the insertion portion of the tissue ablation device. Note that 8 is a water supply cock that is provided diagonally protruding from the rear end side of the grip portion 1 and is connectable to a water supply device (not shown). This water supply cock 8 communicates with the suction passage 4a.

めの電源部１４などから構成される。The monopolar antenna 9 serving as a microwave treatment device is
It is connected to a coaxial cable 10 that is inserted across the passage 4a and the water cock 8 so as to be movable forward and backward. The end of the coaxial cable 10 coming out from the water cock 8 is connected to an external microwave power supply 11 via a connector (not shown), and the microwave power supply 11 connects the monopolar antenna 9 to the microwave power supply 11 . This makes it possible to send the microwave current necessary for emitting waves. In addition,
The microwave power supply device 11 has an oscillation tube (not shown), and includes an oscillation section 12 for sending microwave current to the coaxial cable 10, a cooling section 13 for cooling the oscillation tube, and each oscillation section 12.゜It is composed of a power supply section 14 for supplying power to the cooling section 13 and the like.

そして、こうしたモノポーラ型アンテナ９の進退自在な
設置により、先の超音波切除装置と併せ、組織切除装置
の全体を構成している。By installing the monopolar antenna 9 such that it can move forward and backward, it constitutes the entire tissue resection device together with the above-mentioned ultrasonic ablation device.

。Therefore, when using such a tissue resection device to excise an affected area within a body cavity, the transmission tube 4 is first inserted into the body cavity using, for example, an endoscope. Note that, at this time, the monopolar antenna 9 is retracted into the transmission pipe 4. Next, the tip of the transmission tube 4 is pressed against the target affected area. Thereafter, the monopolar antenna 9 in the transmission tube 4 is moved forward and applied to the affected area, and the microwave power supply device 12 is activated.

これにより、モノポーラ型アンテナ９ヘマイクロ波用電

通じ体外に排出されていく。In other words, the bleeding in the affected area itself is stopped by necrosis. After that, the ultrasonic vibrator 2 and the suction pump are activated to apply ultrasonic vibration and suction to the tip of the transmission tube 4, and the necrotic diseased tissue is excised by the ultrasonic vibration and at the same time. The excised tissue is discharged out of the body through the suction path 4a by suction force.

こうした、あらかじめ生体組織を壊死させてからの切除
は、出血を伴うことなく患部組織を切除ならびに吸引す

せた後、超音波切除装置で切除して吸引すればよい。Specifically, a sheath 26 made of a pipe has a transmission pipe 4 of an ultrasonic ablation device (not shown) inside the scope 28.
The transmission tube 4 and the scope 28 are inserted into the body cavity using the sheath 26 as a guide. A bipolar antenna 27 and a cable 29 connected to the antenna 27 are inserted into the wall of the sheath 26 along the axial direction so as to be movable forward and backward. It goes without saying that the bipolar antenna 27 is arranged at a position where it can be observed from the scope 28. Such a tissue resection device inserts a sheath 26 into a living body cavity, finds an affected area while observing it with a scope 28, applies a bipolar antenna 27 to the affected tissue to cause necrosis of the tissue, and then uses an ultrasonic ablation device to It can be removed and aspirated.
