【0020】本変形例1のフード1は、キャップ部材の外側にチャンネルを追加したものである。 The hood 1 of the first modification is obtained by adding a channel to the outside of the cap member.

【0021】従来の手技において、図20に示すように、高周波スネア9を用いて粘膜6の切除をフード21 [0021] In the conventional technique, as shown in FIG. 20, the hood resection of mucosal 6 using a high frequency snare 9 21
のキャップ部材22の内部で行っているため、大きな粘膜6をキャップ部材22内に吸引した状態では、隙間がほとんどないために、スネアの操作は極めて困難であった。 Because doing inside of the cap member 22, in a state in which sucking the large mucosal 6 within the cap member 22, since there is little clearance, the operation of the snare has been extremely difficult. また、スネアの操作を容易にしようとすると、キャップ部材22内部の隙間を大きくする必要性から、吸引する粘膜6を小さくしなければならず、切除可能な粘膜6も小さくなってしまうという不具合があった。 Also, when you try to facilitate manipulation of the snare, from the need to increase the gap between the inner cap member 22, it is necessary to reduce the mucosal 6 for sucking, inconveniently resectable mucosal 6 also becomes smaller there were.

【0022】ここで、スネアの操作が容易で、且つ大きな粘膜の切除を可能とするために、図8、及び図9に示すように、キャップ10の外側にチャンネル12を接着等の手段により固着した。 [0022] Here, easy operation of snare, and to allow the resection of large mucosa, as shown in FIG. 8, and 9, securing the channel 12 on the outside of the cap 10 by means of adhesive or the like did. このチャンネル12は、一方の開口部をキャップ10の先端近傍に配置し、他方の開口部は内視鏡3に沿って、内視鏡3の有効長とほぼ等しい長さか、又はそれ以上の長さとなるような位置に設定されている。 The channel 12, the one opening is disposed in the vicinity of the tip of the cap 10, the other opening along the endoscope 3, approximately equal length as the effective length of the endoscope 3, or more in length It is set to be to become such a position. なお、チャンネル12の先端側はキャップ10よりも僅かに短く、又斜めにカットされている。 Incidentally, the distal end side of the channel 12 is slightly shorter than the cap 10, and is cut diagonally.

【0023】なお、チャンネル12は、内視鏡3の湾曲等の動きを妨げないように、可撓性の材料、例えば、フッ素樹脂、塩化ビニル、ポリウレタン、ポリエチレン等の軟質合成樹脂を用いて構成するのが望ましい。 [0023] Incidentally, channel 12, so as not to interfere with the movement of the bending or the like of the endoscope 3, flexible material, for example, constructed by using fluorine resin, vinyl chloride, polyurethane, a soft synthetic resin such as polyethylene to is desirable.

【0024】次に、高周波スネア9をキャップ10に組み込む手順を説明する。 [0024] Next, a procedure to incorporate a high-frequency snare 9 to cap 10. 図10に示すように、内視鏡3 As shown in FIG. 10, the endoscope 3

0に設けた外付けのチャンネル12に、高周波スネア9 The external channel 12 of which is provided to the 0, the high-frequency snare 9
を図示しない手元側より挿入し、チャンネル12の先端部から突出させる。 Insert from the proximal not shown, it protrudes from the distal end of the channel 12. そして、スネアワイヤ9aの先端のループをキャップ10に被せておく。 Then, previously covered with a loop at the tip of the snare wire 9a on the cap 10.

【0025】その後は第1実施例と同様に、フード1を取り付けた内視鏡3を患者の体腔内に挿入し、フード1 [0025] Then, as in the first embodiment, by inserting the endoscope 3 fitted with a hood 1 into the body cavity of the patient, the hood 1
のキャップ10先端部を粘膜6に接近させて、先ず粘膜6を吸引する。 The cap 10 tip is brought closer to the mucosa. 6, first sucks the mucosal 6. その後高周波スネア9を前方へ押し出して、スネアワイヤ9aをキャップ10から外して、吸引されずにキャップ10の外に残った粘膜の根元部へ掛ける。 Then push the snare 9 forward, disconnect the snare wire 9a from the cap 10, subjected to the root portion of the remaining mucosa outside of the cap 10 without being sucked. そして、スネアワイヤ9aをスネアシース9bに引き込んで、切除部分の粘膜を引き絞り、スネアワイヤ9 Then, draw the snare wire 9a to the snare sheath 9b, Hikishibori mucosal resection portion, snare wire 9
aに高周波をかけて粘膜を切除する。 To excise the mucous membrane by applying a high frequency to a.

【0026】以上のように構成することにより、スネアワイヤ9aを、吸引して盛り上げた粘膜のより根元側に設定できるため、より大きな粘膜の切除が可能となる。 [0026] By the above configuration, the snare wire 9a, since that can be set to a more root side of the suction to raised mucosa, it is possible to cut a larger mucosal.
また、スネア9の操作をフード1の外の広い範囲で行うため、スネアの操作を容易にすることができる。 Moreover, for operating the snare 9 in a wide range of outer hood 1, it can facilitate manipulation of the snare. 更に、 In addition,
チャンネル12を内視鏡3とは独立して設けたため、内視鏡3を患者の体腔内に残したまま、高周波スネア9の挿脱が可能となり、スネア9の操作が容易となったり、 Because the independently provided with the endoscope 3 channels 12, while the endoscope 3 left in the body cavity of the patient, enables insertion and removal of the high-frequency snare 9, or become the operation of the snare 9 is facilitated,
空になったチャンネル12を利用して他の鉗子等を挿入することも可能となる。 Using the channel 12 becomes empty it is also possible to insert the other forceps or the like.

【0027】ここで、図11に示すように、高周波スネア9のスネアワイヤ9aとスネアシース9bとの成す角度をαに設定することにより、内視鏡3を患者の体腔内に挿入する時や、切除操作時にスネアワイヤ9aがキャップ10から外れてしまい、粘膜の切除ができなくなることを防止できる。 [0027] Here, as shown in FIG. 11, by setting the angle formed by the snare wires 9a and snare sheath 9b of the high-frequency snare 9 alpha, and when the endoscope 3 is inserted into a body cavity of a patient, resection snare wire 9a is deviates from the cap 10 during operation, it can be prevented can not cut the mucosa. なお、この時の角度αは、粘膜の根元部へスネアワイヤ9aを位置させて切除を行い易くするためには、90゜以上の鈍角とすることが望ましいが、患者の体腔内に挿入する時等に、不用意にスネアワイヤ9aがキャップ10から外れることを防止するためには90゜以下の鋭角が望ましい。 The angle α at this time in order to facilitate the ablation by positioning the snare wire 9a to the base portion of the mucosa, it is desirable that the obtuse angle greater than 90 degrees, such as when inserted into a body cavity of a patient to, inadvertently snare wire 9a is in order to prevent from being removed from the cap 10 following acute desirably 90 °. 従って、内視鏡3と高周波スネア9を患者の体腔内に挿入する時の操作性と、粘膜切除時の操作性との両方をバランス良く維持するためには、約90゜前後の角度で構成するのが最も効果的である。 Thus, the operability when inserting the endoscope 3 and the high-frequency snare 9 into a body cavity of a patient, both the operability during mucosal resection to good balance maintained, construction at an angle of about 90 degrees it is most effective to.
