　特許文献１には電気メスと吸引管を一体化した医療器具が開示されているが、ここで用いられている技術は電気メスの使用で発生した煙や洗浄液の排出のためのものであって、病変組織の摘出量を調整することは困難である。また、特許文献２には吸引管の圧力制御を自動化する技術が開示されている。しかしこの技術は安定した吸引を実現するためのもので、病変組織の摘出量を調整することは困難である。 Patent Document 1 discloses a medical instrument in which an electric knife and a suction tube are integrated, but the technique used here is for discharging smoke and cleaning liquid generated by using an electric knife. It is difficult to adjust the amount of excised diseased tissue. Patent Document 2 discloses a technique for automating the pressure control of the suction pipe. However, this technique is intended to realize stable suction, and it is difficult to adjust the amount of diseased tissue removed.

　本発明の一実施形態に係る病変組織摘出装置の実施形態を図面に基づいて説明する。図１はその病変組織摘出装置で用いる吸引管２の断面図を示している。吸引管２は導電性材料で作られており、さらに吸引管２の端面を含む先端部の外面は絶縁材料３で絶縁されている。また吸引管２の外面の一部は導電性材料が露出している。吸引管２の材質はステンレス鋼、コバルトクロム合金、チタン合金、チタン、銀、金、真鍮が好適である。 Embodiments of a diseased tissue extraction apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a cross-sectional view of a suction tube 2 used in the diseased tissue extraction apparatus. The suction tube 2 is made of a conductive material, and the outer surface of the tip including the end surface of the suction tube 2 is insulated by an insulating material 3. Further, the conductive material is exposed on a part of the outer surface of the suction tube 2. The material of the suction tube 2 is preferably stainless steel, cobalt chromium alloy, titanium alloy, titanium, silver, gold, or brass.
　図２は病変組織摘出装置１の全体構成を示す模式図である。病変組織摘出装置１は、吸引管２と、吸引管２に負圧を与える真空ポンプ８と、吸引管２内の圧力を調整する真空レギュレータ７と、吸引管２に接続された電気メス装置２０と、吸引管２で摘出した病変組織を貯留する吸引瓶６と、真空レギュレータ７および電気メス装置２０を制御するコンピュータ１０と、からなる。 FIG. 2 is a schematic diagram showing the overall configuration of the lesion tissue extraction apparatus 1. The lesion tissue extraction device 1 includes a suction tube 2, a vacuum pump 8 that applies a negative pressure to the suction tube 2, a vacuum regulator 7 that adjusts the pressure in the suction tube 2, and an electric knife device 20 connected to the suction tube 2. And a suction bottle 6 for storing the diseased tissue removed by the suction tube 2, and a computer 10 for controlling the vacuum regulator 7 and the electric knife device 20.
　図２に示すように、吸引管２の後端はコネクタ４を介してチューブ５に接続されている。チューブ５は吸引瓶６に接続され、さらに真空レギュレータ７を経由し、真空ポンプ８に接続されている。 As shown in FIG. 2, the rear end of the suction pipe 2 is connected to the tube 5 via the connector 4. The tube 5 is connected to a suction bottle 6 and further connected to a vacuum pump 8 via a vacuum regulator 7.
　吸引管２の露出した導電性材料部には通電ケーブル２１が接続されており、さらに通電ケーブル２１は電気メス装置２０に接続されている。電気メス装置２０には接続ケーブル２３を介して対極板２２が接続されている。 A conductive cable 21 is connected to the exposed conductive material portion of the suction tube 2, and the conductive cable 21 is further connected to the electric knife device 20. A counter electrode plate 22 is connected to the electric knife device 20 via a connection cable 23.
　チューブ５は吸引管２に負圧を与え、また吸引管２が摘出した病変組織を吸引瓶６まで移送する。 The tube 5 applies a negative pressure to the suction tube 2, and transports the diseased tissue extracted by the suction tube 2 to the suction bottle 6.
　真空レギュレータ７は真空レギュレータ制御ケーブル１１を介して制御コンピュータ１０に接続されており、制御コンピュータ１０の制御信号によって設定圧が変化する。また電気メス装置２０は電気メス装置制御ケーブル１２を介して制御コンピュータ１０に接続されており、制御コンピュータ１０の制御信号によって、電気メス出力設定値が変化し、また電気メス出力の開始および停止が制御される。 The vacuum regulator 7 is connected to the control computer 10 via the vacuum regulator control cable 11, and the set pressure changes according to the control signal of the control computer 10. The electric knife device 20 is connected to the control computer 10 via the electric knife device control cable 12, and the electric knife output setting value is changed by the control signal of the control computer 10, and the electric knife output is started and stopped. Be controlled.
　病変組織摘出装置１に必要な負圧は真空ポンプ８によって与えられる。真空ポンプ８によって生じた負圧は、真空レギュレータ７によって設定された圧力に調整され、吸引管２に負圧を与える。真空レギュレータ７には圧力センサが取り付けられており、吸引管２の負圧を確認できるようになっていることが望ましいが、別途圧力センサを吸引瓶６またはチューブ５または吸引管２に取り付けても良い。 The negative pressure necessary for the diseased tissue extraction device 1 is given by the vacuum pump 8. The negative pressure generated by the vacuum pump 8 is adjusted to the pressure set by the vacuum regulator 7 and gives a negative pressure to the suction pipe 2. It is desirable that a pressure sensor is attached to the vacuum regulator 7 so that the negative pressure of the suction pipe 2 can be confirmed. However, a separate pressure sensor may be attached to the suction bottle 6 or the tube 5 or the suction pipe 2. good.
　次に病変組織摘出の手順について説明する。病変組織摘出装置１における病変組織の摘出量調整は吸引管２の負圧による引っ張り力を調整することで実現している。図３Ａ～Ｄは病変組織摘出時の吸引管２の先端部分を示している。図３Ａのように吸引管２の先端を細胞組織３０の摘出部位３１に接触させる。このとき吸引管２には負圧を与えない。また吸引管２と摘出部位３１の間にすき間ができてはいけない。さらに対極板２２は細胞組織３０と電気的に接続されている。 Next, the procedure for removing the lesion tissue will be described. Adjustment of the amount of the diseased tissue extracted by the diseased tissue extraction apparatus 1 is realized by adjusting the pulling force due to the negative pressure of the suction tube 2. 3A to 3D show the distal end portion of the suction tube 2 at the time of excision of a diseased tissue. As shown in FIG. 3A, the tip of the suction tube 2 is brought into contact with the excision site 31 of the cell tissue 30. At this time, no negative pressure is applied to the suction pipe 2. In addition, there should be no gap between the suction tube 2 and the extraction site 31. Further, the counter electrode plate 22 is electrically connected to the cell tissue 30.
　制御コンピュータ１０からの制御信号により真空レギュレータ７を調整し、吸引管２に負圧を与えると吸引管２の内部に引っ張り力が発生し、図３Ｂのように摘出部位３１が吸い込まれる。吸い込まれる摘出部位３１の量は、負圧により吸引管２に発生した引っ張り力によって変化する。 When the vacuum regulator 7 is adjusted by a control signal from the control computer 10 and a negative pressure is applied to the suction tube 2, a pulling force is generated inside the suction tube 2, and the extracted portion 31 is sucked as shown in FIG. 3B. The amount of the extracted portion 31 that is sucked varies depending on the pulling force generated in the suction tube 2 due to negative pressure.
　図３Ｂの状態で吸引管２に電気メス装置２０から高周波電流を流すと、吸引管２の 
内側に接触している摘出部位３１が焼灼され、図３Ｃのように細胞３０と摘出部位３１で分離される。 When a high frequency current is passed from the electric knife device 20 to the suction tube 2 in the state of FIG.
The excision site 31 in contact with the inside is cauterized and separated at the cell 30 and the excision site 31 as shown in FIG. 3C.
　吸引管２を細胞組織３０から離すと、分離された摘出部位３１は吸引管２の負圧によってチューブ５を移送されて吸引瓶６に貯留される。その結果、図３Ａにおいて細胞組織３０にあった摘出部位３１は、図３Ｄのように摘出による凹み３２となる。 When the suction tube 2 is separated from the cell tissue 30, the separated excision site 31 is transferred to the tube 5 by the negative pressure of the suction tube 2 and stored in the suction bottle 6. As a result, the extracted portion 31 in the cell tissue 30 in FIG. 3A becomes a dent 32 by extraction as shown in FIG. 3D.
　次に、上記した病変組織摘出装置１を使用して行った豚脳細胞摘出実験結果を示す。吸引管２に外径２ｍｍ、内径１．５ｍｍ、長さ７０ｍｍのステンレス管を用い、このステンレス管先端５ｍｍの外面に絶縁材料３として絶縁塗料を塗布している。 Next, the results of pig brain cell extraction experiments performed using the above-described lesion tissue extraction apparatus 1 are shown. A stainless steel tube having an outer diameter of 2 mm, an inner diameter of 1.5 mm, and a length of 70 mm is used for the suction tube 2, and an insulating paint is applied as an insulating material 3 to the outer surface of the stainless steel tube tip 5 mm.
　制御コンピュータ１０を用いて電気メス装置２０を切開モード、出力３０Ｗ、通電時間１秒間に設定した。さらに制御コンピュータ１０を用いて真空レギュレータ７の設定圧力を－３、－６、－９、－１２、－１５ｋＰａの５パターンで豚脳細胞摘出を行った。 The electric scalpel device 20 was set to an incision mode, an output of 30 W, and an energization time of 1 second using the control computer 10. Further, porcine brain cells were extracted using the control computer 10 in five patterns of -3, -6, -9, -12, and -15 kPa at the set pressure of the vacuum regulator 7.
　図４は豚脳の灰白質を摘出対象とした実験結果を示す顕微鏡写真である。図４内の符号４０～４４はそれぞれ真空レギュレータ７を－３、－６、－９、－１２、－１５ｋＰａに設定して摘出を行った後の摘出痕である。真空レギュレータ７の設定圧を変化させると摘出量も変化することがわかる。 FIG. 4 is a photomicrograph showing the experimental results for the gray matter of pig brain. Reference numerals 40 to 44 in FIG. 4 denote extraction marks after extraction with the vacuum regulator 7 set to −3, −6, −9, −12, and −15 kPa, respectively. It can be seen that when the set pressure of the vacuum regulator 7 is changed, the extraction amount also changes.
　このように本実施形態では、吸引管２の露出した導電性材料部が通電ケーブル２１を介して電気メス装置２０に接続され、吸引管２が電気メス電極としても機能するようになっているので、真空レギュレータ７の圧力調整および電気メス装置２０の出力調整により、病変組織の摘出量を制御することができる。 Thus, in the present embodiment, the exposed conductive material portion of the suction tube 2 is connected to the electric knife device 20 via the energizing cable 21, and the suction tube 2 functions as an electric knife electrode. The amount of diseased tissue removed can be controlled by adjusting the pressure of the vacuum regulator 7 and adjusting the output of the electric knife 20.
