となり又、偏角の部分が盲点となり、顕微鏡下手
術では不都合が生じる場合がしばしばあつた。(Prior Art) As shown in FIG. 11, in conventional forceps of this type, the clamping tip 1 is deviated upward at an angle θ 0 . Therefore, when a clip 2 of a predetermined length is held, the angular width W 0 with respect to the reference line P 0
As the angle becomes wider, the area or space occupied during surgery becomes larger, and the declination angle becomes a blind spot, which often causes inconvenience in surgery under a microscope.
又、偏角基準ラインQ0からの長さL0も長くな
るという欠点があつた。 Further, there was a drawback that the length L 0 from the declination reference line Q 0 also became long.
（技術的課題）

θ1で下向き5°，10°，15°，20°等種々の角度のもの
を用途に適応させて選定して形成してある。従つ
て、このえぐり挟持部１６にクリツプ１７を挟持
せしめると第３図に示す如く基準ラインＰに対し
角θで挟持せしめられることとなる。 13 is a support shaft, 14 is a band-shaped spring portion, and 15 is an engagement member. When the pair of engagement members 15 are disengaged, the pair of operation grips 11 move along the arrow A and the center around the support shaft 13. It moves in the direction B, and the pair of clip holding tips 12 also move in the directions C and D, respectively, to open. 16 is the clip holding tip 12
An angle θ is formed at an angle θ with respect to the reference line P by a hollowed-out holding portion formed inside the reference line P. The angle θ is 5°, 10°, 15°, 20°, 45° upward, or 5°, 10°, 15°, 20° downward with an angle θ 1 relative to the reference line P 1 . It has been selected and formed to suit. Therefore, when the clip 17 is held by this gouged holding part 16, it will be held at an angle θ with respect to the reference line P, as shown in FIG.
１８はクリツプ１７のバネ基部、１９はクリツ
プ１７の挟持部であり該クリツプ１７はコバルト
クローム合金製で手術後は体内に残すものであ
る。 18 is a spring base of the clip 17, and 19 is a holding portion of the clip 17. The clip 17 is made of cobalt chrome alloy and is left in the body after surgery.
２０は動脈で、２１は風船状に膨れた患部であ
る。 20 is an artery, and 21 is an affected area swollen like a balloon.
（作用） 上記の技術的手段は下記の如く作用する。(effect) The above technical means works as follows.
第２図に示した鉗子本体１０に於ける一対の係
合部材１５による係止を解くと一対の操作把持部
１１は夫々矢標Ａ及びＢ方向に移動すると共に一
対のクリツプ挟持先端部１２も支軸１３を中心と
して矢標Ｃ及びＤ方向に夫々移動し開口する。 When the pair of engagement members 15 on the forceps body 10 shown in FIG. It moves in the directions of arrows C and D centering on the support shaft 13 and opens.
然る後、クリツプ１７のバネ基部１８をクリツ
プ挟持先端部１２のえぐり挟持部１６に挿入し一
対の操作把持部１１を反矢標Ａ及びＢ方向に操作
し、一対の係合部材１５を係合せしめるとクリツ
プ１７は一対の挟持部１９を開き且つ角θでもつ
て偏角された状態でえぐり挟持部１６に装着され
る。（第３図，第４図参照）次いで、術者が顕微
鏡（図示せず）を視覗しながら鉗子本体１０を操
作し動脈２０の患部２１にクリツプ１７を挟持す
ればよい。 After that, the spring base 18 of the clip 17 is inserted into the gouged gripping part 16 of the clip gripping tip 12, and the pair of operation gripping parts 11 are operated in the opposite directions of arrows A and B to engage the pair of engaging members 15. When the clips 17 are brought together, the clip 17 opens the pair of clamping parts 19 and is attached to the scooped clamping part 16 in a state of being deflected at an angle θ. (See FIGS. 3 and 4) Next, the operator operates the forceps body 10 while looking through a microscope (not shown) to clamp the clip 17 on the affected area 21 of the artery 20.
