CLAIMS AND METHODS FOR CLINICAL ANEURYSM CLIP OF CLOSED END TYPE

The present invention relates to a clip used for ligation of a cerebral aneurysm, and more particularly, to a clip used for ligation of a cerebral aneurysm clip so as to be arranged in a closed-end form such as a loop shape, End type of an aneurysm clip capable of improving the safety and convenience of ligation of blood vessels or cerebral aneurysms and enhancing ligation efficiency to improve the success rate of ligation.

An aneurysm is a disease in which a part of the artery is defected and the part is swollen like a balloon to form an acute angle and then it is killed or serious damage occurs at a certain moment. Conventionally, an arterial blood flow is blocked, Stents were used or surgical methods were used.

As disclosed in Laid-Open Patent Publication No. 10-2012-0009329 (published on Jan. 21, 2012), an operative method for blocking the flow of blood into the aneurysm or preventing the bleeding site, which is conventionally used, is aneurysm ligation and aneurysm embolization.

An aneurysmal ligation is used to cure the aneurysm. When the aneurysm is used to cure the aneurysm, the head is cut through a micro-microscope to locate the aneurysm and approach the aneurysm and ligate the neck of the aneurysm with a small clip.

The aneurysm ligation procedure is complicated, but the operation is required even if the aneurysm is too deep in the brain or surrounded by dangerous structures. In particular, when ligation of an aneurysm of the brain, it is necessary to expose the neck of the balloon type to prevent the rupture and to prevent the aneurysm from becoming larger.

However, in the past, the ligation of the aneurysm clip, that is, the tip of the blade of the aneurysm clip, is composed of an open end type such as a tweezers or a tongue, And the operation procedure becomes complicated. For example, especially when there is a serious risk of exfoliation due to excessive adhesion to the surrounding tissues, conventional aneurysm clips having an open-ended blade tip tend to incomplete ligation or give up ligation.

In addition, in the past, when the aneurysm was swollen like a balloon or lined with an acute aneurysm, the aneurysm had to undergo an exfoliation process so that the neck of the aneurysm could be ligated correctly. In addition, the conventional aneurysm clips with the blade tip made of an open-ended type have problems such as ligating the adjacent aneurysm other than the aneurysm that is ligated, and ligating together the aneurysm. Therefore, I had to endure a dangerous process.

In addition, due to the structural shape of the conventional aneurysm clip, which consists of an open-ended blade tip, a large aneurysm and an aneurysm that can not find the origin of the aneurysm and the origin of the aneurysm, And a hard aneurysm such as arteriosclerosis was not able to guarantee its safety because it had a problem again after ligation.
