ツプとした。Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a spring part that extends by one rotation so as to bias both ends in the opening direction, and a spring part that intersects with each other in an X-shape from this spring part so that one end is An intersection part that passes through the other through-hole and is slidably engaged, and a semicircular shape that closely presses the tips of the intersection part to each other in a straight line and extends along the blood vessel in a direction perpendicular to the plane of the spring part. This is a clip for use in aneurysm and other surgical operations, consisting of a curved clamping part.
作 用
本考案では交差部より先端を互いに直線状に密
圧着すると共に前記スプリング部の平面に対して
直角方向で血管に沿う半円形状に弯曲した挟持部
としたので、血管周辺に密接近すると共に従来の
クリツプによる場合のように接線上の接触ではな
く、血管の外縁に沿つて広く接触するようにし
た。Function: In the present invention, the tips of the spring parts are closely pressed together in a straight line from the intersection part, and the clamping part is curved in a semicircular shape along the blood vessel in a direction perpendicular to the plane of the spring part, so that it can be closely approached around the blood vessel. In addition, the contact is made broadly along the outer edge of the blood vessel, rather than tangential contact as is the case with conventional clips.
この挟持部はスプリング部の平面に対して直角
方向であるので、スプリング部に鉗子を用いて先
端を開く場合、術野の障碍にもならない。 Since this clamping part is perpendicular to the plane of the spring part, it does not obstruct the surgical field when the tip of the spring part is opened using forceps.
実施例
以下、実施例として示した図面につき説明す
る。Embodiment Hereinafter, drawings shown as embodiments will be explained.

グ部１の平面に対して直角方向で血管に沿う半円
状に弯曲している。 FIG. 1 is an enlarged perspective view of the clip of the present invention. Reference numeral 1 denotes a spring portion, which rotates once and extends in both directions to bias both ends in the opening direction. Reference numeral 2 denotes an intersection where both ends of the spring portion 1 intersect with each other in an X-shape, and one passes through the through hole 3 of the other and is slidably engaged with the other. Reference numeral 4 denotes a clamping portion which closely presses the tips of the intersection portions 2 to each other linearly and is curved in a semicircle along the blood vessel in a direction perpendicular to the plane of the spring portion 1.
第２図は挟持部４が血管の周縁に沿つて半円状
に弯曲した形を示し、又、第３図は直線状に延び
た形を示している。挟持部４は第４図に示すよう
に鉗子５を用いてスプリング部１の先端を両方か
ら押圧することにより開放し、鉗子５を離せばス
プリング部１の弾性により元に戻つて血管瘤を挟
持し止血できるようになつている。 FIG. 2 shows a shape in which the holding part 4 is curved in a semicircle along the circumference of the blood vessel, and FIG. 3 shows a shape in which it extends linearly. As shown in FIG. 4, the clamping part 4 is opened by pressing the tips of the spring part 1 from both sides using forceps 5, and when the forceps 5 are released, it returns to its original position due to the elasticity of the spring part 1 and clamps the vascular aneurysm. I am now able to stop the bleeding.
第５図Ａは動脈６の周縁で瘤７，８が反円形状
に近い広い範囲にある場合、又、Ｂは瘤１０，１
１が近接してできた場合を示し、いずれの場合も
本考案クリツプ９により、瘤７，８及び１０，１
１のネツク部を同時に挟持した例を示している。
尚、クリツプの挟持部４の半円形状の弯曲は動脈
の径に応じて大小数種類を用いることができる。 FIG. 5A shows a case where the aneurysms 7 and 8 are in a wide range near the anticircular shape at the periphery of the artery 6, and B shows a case where the aneurysms 10 and 1
1 are formed close to each other, and in both cases, the clip 9 of the present invention creates bumps 7, 8 and 10, 1
This shows an example in which two neck portions are held together at the same time.
The semicircular curve of the holding portion 4 of the clip may be of various sizes depending on the diameter of the artery.
考案の効果
本考案は上記のように交差点より先端の挟持部
を直線状に密圧着すると共にスプリング部の平面
に対して直角方向で血管に沿う半円形状に弯曲す
るようにしたので、血管壁に対して瘤が広く半円
状に存在する場合や２つ以上の瘤が近接して半円
状に存在する場合にも挟持部の接触部分が大き
く、同時に挟持することてができるようになつ
た。従つて、従来例のように近接する２つの動脈
瘤に対し、又、ネツク部が半円形状に近く広い場
合にも１つのクリツプで足り、２つのクリツプを
使用する手間もなく、脳外科手術のように顕微鏡
下の手術においても術野の障碍にもならず、容易
に使用できる等その実用上の効果は大きい。Effects of the invention As described above, the present invention tightly presses the clamping part at the tip from the intersection in a straight line, and curves it in a semicircular shape along the blood vessel in a direction perpendicular to the plane of the spring part, so that it does not disturb the blood vessel wall. On the other hand, even when the bump is wide and semicircular, or when two or more bumps are close to each other in a semicircular shape, the contact area of the clamping part is large, making it possible to clamp them at the same time. Ta. Therefore, one clip is sufficient for two aneurysms that are close to each other as in the conventional case, or when the neck part is semicircular and wide, and there is no need to use two clips. It does not obstruct the surgical field even in surgery under a microscope and is easy to use, so it has great practical effects.
