Background
Aneurysms, which are the manifestations of localized or diffuse dilatation or bulging of the arterial wall due to lesions or lesions of the arterial wall, can occur in any part of the arterial system, mainly represented by distending or pulsating masses, and are more common in the trunk arteries, aorta and carotid arteries of limbs. Aneurysms vary in treatment from site to site. The main treatment is surgical treatment, aneurysm intraluminal repair and aneurysm embolization. The operation principle includes aneurysm excision and artery reconstruction. The reconstruction method comprises the steps of repairing the broken opening of the artery, restraining the arterial patch, performing end-to-end anastomosis of the artery and the like. The endovascular repair adopts a tectorial artificial endovascular stent to carry out aneurysm endovascular repair, has small wound and definite curative effect, but must be strictly mastered to have good indications. For some visceral aneurysms, a coil spring embolization method can be used to form thrombus in a tumor body and avoid further expansion of the tumor body to break bleeding.
In order to cut off aneurysms, people invent aneurysm clamps, at present, most of the existing aneurysm clamps need doctors to control force to exert clamping force all the time, so that the operation is easily influenced, unnecessary injury is easily caused to patients due to poor force, and the aneurysm clamps are inconvenient and not beneficial to popularization and use.
