Articulating aneurysm clips

Abstract

The invention discloses a joint-type aneurysm clip, which comprises two clamping arms which are integrally connected by virtue of an elastic device and are capable of opening and closing, wherein a parallelism-keeping device is connected between the two clamping arms; each of the two clamping arms comprises at least two joint arms, and the two adjacent joint arms are hinged by virtue of a hinge shaft; the axial direction of the hinge shafts is consistent with the opening / closing direction of the clamping arms; an inserting groove is formed in one of two adjacent joint arms and an inserting head, which extends into the inserting groove, is arranged on the other joint arm; slotted holes, in which pin shafts are inserted and are capable of rotating, are formed in the joint arms which are provided with the inserting heads; elastic pads are arranged at the bottoms of the slotted holes; the pin shafts are inserted from the inner sides of the joint arms which are provided with the inserting grooves and extend out of the outer sides of the joint arms; press contacts are arranged on the extending parts of the pin shafts; and locking and opening / closing devices are arranged between the pin shafts and the joint arms. The joint-type aneurysm clip disclosed by the invention is simple in structure, and the joint-type aneurysm clip has the advantages of being concrete in aneurysm clamping effect, short in operation time, low in operation cost, and being capable of relieving patient's pain and effectively avoiding recurrence of diseases.

Description

technical field [0001] The invention relates to an articulating aneurysm clip. Background technique [0002] Intracranial aneurysm is a tumor-like protrusion of the arterial wall caused by the localized abnormal expansion of cerebral arteries. The danger is rupture and bleeding, which is commonly referred to as cerebral hemorrhage. At present, the most effective method for treating aneurysms is aneurysm clipping. [0003] When performing aneurysm clipping, an aneurysm clip needs to be used to open the aneurysm clip through the clamping forceps, and the two clamping arms of the aneurysm clip clamp the aneurysm on the cerebral artery, so as to realize the aneurysm protruding Blood blocking. Due to the small range of surgical field in craniotomy and the various shapes of aneurysms on the cylindrical cerebral artery, it is difficult to clamp the aneurysm with a uniform type of aneurysm clip, so it is necessary to design a variety of shapes Aneurysm clips, resulting in an incr...

Problems solved by technology

Due to the small range of surgical field in craniotomy and the various shapes of aneurysms on the cylindrical cerebral artery, it is difficult to clamp the aneurysm with a uniform type of aneurysm clip, so it is necessary to design a variety of shapes Aneurysm clips, resulting in an increase in production costs. In addition, if you encounter aneurysms protruding from multiple sides of the cerebral artery, it is difficult to clamp them with one aneurysm clip. When using multiple aneurysm clips, it will inevitably leave If there is a lower clamping gap, it is easy to cause the failure of the above clipping operation, resulting in incomplete clipping of the aneurysm or recurrence of the aneurysm.
