て動脈瘤をクリップするのに用いる脳内勤脈瘤クリップ
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an intracerebral aneurysm clip used to clip an aneurysm.
上記用途に用いるクリップは、脳内動脈瘤を完全に遮断
できるものでなければならず、然も手術後脳内に残存す

われていたが、上記要請に十分応え得るものではなかっ
た。The clip used for the above purpose must be able to completely block off the intracerebral aneurysm, and since it remains in the brain after surgery, it is not possible to continue chrysoping almost permanently. There must be. In particular, in this clipping, arterial pulsations can cause sideways slipping, and the surface of the aneurysm is slimy with body fluids, making it easy for the clip to slip and come off. Conventionally, therefore, the clip has been formed with unevenness to prevent slipping, but this method has not been able to fully meet the above requirements.
そこで本発明は、操作が簡単で脳内動脈瘤を確実に遮断
することができ、然も術後ずれ動いたり、外れたりする
虞がない脳内動脈瘤クリソプを提供することを目的とす
るものである。Therefore, an object of the present invention is to provide an intracerebral aneurysm chrysop that is easy to operate, can reliably block an intracerebral aneurysm, and has no risk of shifting or coming off after surgery. It is.

じるよう作用する。The present invention relates to an intracerebral aneurysm chrysop, which is characterized in that the upper and lower blades are bent into a W-shaped cross section, a V-shaped cross section, etc., and a part of the stopper is formed by wrapping the tip of the lower blade. shows an example thereof. 1 in the diagram
2 is an upper blade, and 2 is a lower blade, which are overlapped and pivotally connected at a fulcrum shaft 3. Lower blade 2 is upper blade 1
The stopper portion 4 is formed by wrapping the tip of the stopper. Further, usually the upper blade 1 and/or the lower blade 2 are provided with a large number of recesses 5 in parallel. Reference numeral 6 denotes a spring sheathed on the fulcrum shaft 3, which acts to constantly push open the distal ends of the upper blade 1 and the lower blade 2, thereby closing their distal ends.

ことは皆無となる。The clip according to the invention is used in the same manner as conventional clips. That is, by applying pressure to the distal ends of the upper blade 1 and the lower blade 2 with special forceps, pinching the aneurysm so that the distal ends are expanded), and then removing the pressure on the distal ends of the aneurysm. , the tip is strongly closed by the action of the spring 6, and crimping is completed. By the way, in the present invention, since the stopper portion 4 is provided, there is no possibility that the clip will shift in its longitudinal direction, resulting in incomplete blocking of the aneurysm, or falling off.
また、上側ブレード１及び下側ブレード２は、断面Ｗ字

脈瘤として理想的なものといえる。In addition, the upper blade 1 and the lower blade 2 are bent into a W-shaped cross section, a ■-shaped cross section, etc., and are provided with a large number of concave portions 5 in parallel, so that they do not shift or move in the lateral direction. It can be said to be ideal as an aneurysm.
本発明は上述した通りであるから、脳内動脈瘤を確実に
クリップすることができ、然も、術中、術後を問わずず
れ動いたり、外れたりすることがない効果がある。Since the present invention is as described above, it is possible to reliably clip an intracerebral aneurysm, and it has the effect of not shifting or coming off either during or after the surgery.
