Description

本発明は、胃、小腸、大腸等の管腔臓器の壁の外表面に吸着によって固定され、管腔臓器内を密閉状態に保持する管腔臓器壁密閉固定器具に関する。   The present invention relates to a luminal organ wall sealing and fixing device that is fixed to the outer surface of a wall of a luminal organ such as the stomach, small intestine, and large intestine by adsorption and holds the luminal organ in a sealed state.

従来、臓器を手術する際に用いられる器具として、対象部位に吸着させる吸引カップを備えた器具が提案されている（例えば、特許文献１、２参照。）。   Conventionally, as an instrument used when operating an organ, an instrument provided with a suction cup to be adsorbed to a target site has been proposed (see, for example, Patent Documents 1 and 2).

特許文献１には、半球体、及びこの半球体の中央から内側に突出し、組織領域に圧力を加えて止血する閉鎖部材を有する吸引カップと、閉鎖部材に形成された開口部に連結され、空気を排出するためのチューブとを備えた止血制御装置が開示されている。   In Patent Document 1, a hemisphere, a suction cup that protrudes inward from the center of the hemisphere, and has a closing member that stops blood by applying pressure to the tissue region, and an opening formed in the closing member are connected to the air. A hemostasis control device including a tube for discharging the blood is disclosed.

特許文献２には、内視鏡の先端に設けられた吸引カップと、吸引カップ内に挿入され、胃壁組織の一部を引っ張る針とを備えた組織穿刺装置が開示されている。   Patent Document 2 discloses a tissue puncture device that includes a suction cup provided at the distal end of an endoscope and a needle that is inserted into the suction cup and pulls a part of stomach wall tissue.

一方、胃内発育型腫瘍を腹腔鏡下で切除する術式は、過剰な胃壁を切除するものであり、様々な胃機能が失われることから、近年、腹腔鏡と内視鏡を用いた胃局所切除（laparoscopy endoscopy cooperative surgery:以下「ＬＥＣＳ」という。）が試みられている。このＬＥＣＳは、内視鏡下で内視鏡手術用電気メス（ＩＴナイフ）により腫瘍の周囲の全層を約４／５切除し、この切除した箇所を腹腔内に反転し、切除した箇所を縫合するというものである。これにより過剰な胃壁切除を避けることができる。   On the other hand, the surgical procedure for excision of intragastric growth type tumors under the laparoscope is to remove excess gastric wall, and various gastric functions are lost. Local excision (laparoscopy endoscopy cooperative surgery: hereinafter referred to as “LECS”) has been attempted. In this LECS, about 4/5 of the entire layer around the tumor is resected with an electrosurgical scalpel (IT knife) under an endoscope, the resected part is inverted into the abdominal cavity, and the resected part is removed. It is to sew. This avoids excessive gastric wall resection.

特表２０１１−５１０７７８号公報Special table 2011-510778 gazette 特表２０１１−５１９６１３号公報Special table 2011-519613 gazette

「胃粘膜下腫瘍に対する新しい術式：腹腔鏡・内視鏡合同胃局所切除」、日消外会誌、41巻、9号、1661p-1668p、2008年9月"New surgical technique for gastric submucosal tumor: laparoscopic and endoscopic combined local excision of stomach", Jisso Gakaikai, Vol. 41, No. 9, 1661p-1668p, September 2008

しかし、ＬＥＣＳは、従来法と比較して手術時間が約３０分長くなるため、執刀医に負担となる。また、ＬＥＣＳは、腫瘍を含む胃壁を腹腔内に反転する術式であるため、腫瘍細胞が腹腔内に散布するおそれがある。特許文献１、２に記載された吸引カップは、カップの内側の空間全体を吸引するため、ＬＥＣＳに適用しようとすると、対象部位までも吸引してしまうことから、ＬＥＣＳへの適用は難しい。   However, LECS is a burden on the surgeon because the operation time is about 30 minutes longer than the conventional method. Further, since LECS is a technique for inverting the stomach wall containing a tumor into the abdominal cavity, there is a possibility that tumor cells may be dispersed in the abdominal cavity. Since the suction cups described in Patent Documents 1 and 2 suck the entire space inside the cup, if the suction cup is applied to LECS, the target part is also sucked, so that it is difficult to apply to LECS.

したがって、本発明の目的は、執刀医の負担を軽減でき、理想的な腫瘍の切除を可能とする管腔臓器壁密閉固定器具を提供することにある。   Accordingly, an object of the present invention is to provide a luminal organ wall sealing and fixing device that can reduce the burden on the surgeon and enables an ideal tumor to be excised.

The mirror 12 is inserted into the abdominal cavity 101. The protrusion 23 is grasped by the grasping portion 13a of the grasping forceps 13, and the cup portion 2 and the tube 3 are inserted into the abdominal cavity 101 from the other trocar 11B while the cup portion 2 is folded.

次に、腹壁１００の別の箇所に切開口１００ｃを形成して把持鉗子等によってチューブ３の一部を外側に引き出し、チューブ３の端部にコネクタ４を装着し、コネクタ４を図示しない吸引装置に接続する。次に、図４（ｂ）に示すように、胃壁１０２の表面にカップ部２の周縁部２０を接触させ、コネクタ４に接続された吸引装置により吸引を行う。これにより、カップ部２の空間２１が低圧になり、周縁部２０が胃壁１０２に密着する。   Next, an incision 100c is formed in another part of the abdominal wall 100, a part of the tube 3 is pulled out by gripping forceps or the like, the connector 4 is attached to the end of the tube 3, and the connector 4 is not shown. Connect to. Next, as shown in FIG. 4B, the peripheral portion 20 of the cup portion 2 is brought into contact with the surface of the stomach wall 102, and suction is performed by a suction device connected to the connector 4. Thereby, the space 21 of the cup part 2 becomes a low pressure, and the peripheral part 20 adheres to the stomach wall 102.

次に、図４（ｃ）に示すように、先端に内視鏡手術用電気メス（ＩＴナイフ）１５を備えた胃内視鏡１４を食道１０４から胃１０３内に挿入し、胃壁１０２の対象領域１０２ａをＩＴナイフ１５で切除する。このとき、胃１０４には胃内視鏡１４から空気が送られ、胃１０４が膨らんだ状態で胃壁１０２の切除が行われる。カップ部２が対象領域１０２ａを含むように胃壁１０２の外表面に密着しているため、胃壁１０２を切除しても胃１０４内の圧力が一定に保たれる。   Next, as shown in FIG. 4 (c), a gastroscope 14 having an electrosurgical scalpel (IT knife) 15 at the tip is inserted into the stomach 103 from the esophagus 104, and the target of the stomach wall 102 is inserted. The region 102 a is excised with the IT knife 15. At this time, air is sent from the stomach endoscope 14 to the stomach 104, and the stomach wall 102 is excised with the stomach 104 inflated. Since the cup portion 2 is in close contact with the outer surface of the stomach wall 102 so as to include the target region 102a, the pressure in the stomach 104 is kept constant even when the stomach wall 102 is excised.

（第１の実施の形態の作用、効果）
第１の実施の形態によれば、以下の作用、効果を奏する。
（１）本器具１を用いないＬＥＣＳと比較して、手術時間が短くなるので、執刀医の負担を軽減できる。
（２）腫瘍が発育した箇所及びその周辺 だけを切除することができるので、理想的な腫瘍の切除が可能になる。
（３）周縁部２０のみを密着させているので、カップの内側の空間全体を吸引する従来の吸引カップとは異なり、対象部位を吸引しないため、ＬＥＣＳへの適用が容易になる。 (Operation and effect of the first embodiment)
According to the first embodiment, the following operations and effects are achieved.
(1) Compared with LECS that does not use this instrument 1, the operation time is shortened, so the burden on the surgeon can be reduced.
(2) Since only the site where the tumor has grown and its periphery can be excised, an ideal tumor can be excised.
(3) Since only the peripheral edge portion 20 is in close contact, unlike the conventional suction cup that sucks the entire space inside the cup, the target portion is not sucked, and therefore, application to LECS is facilitated.
