Microcatheter shaping auxiliary support for aneurysm interventional operation and preparation method of support

Abstract

The invention discloses a microcatheter shaping auxiliary support for aneurysm interventional operation and a preparation method of the support. A hand-held mechanism further includes a template mechanism for installing a template and a shaping mechanism for fixing a microcatheter, the template mechanism is arranged at the front end of the hand-held mechanism, first fixing bars are arranged on both sides of the template mechanism, and the shaping mechanism is arranged at the lower end of the template mechanism; and second fixing bars are arranged at both ends of the shaping mechanism, and a connection mechanism is arranged between the first fixing bars and the second fixing bars. The support has a reasonable structure, adopts a separate structure, is simpler and more convenient to operatewhen a model and the microcatheter are installed and fixed, and the shaping mechanism can be used to better fix and shape the microcatheter and improve the processing accuracy of the microcatheter.

Description

technical field [0001] The invention relates to the field of aneurysm interventional surgery, in particular to a microcatheter shaping auxiliary brace for aneurysm interventional surgery and a manufacturing method thereof. Background technique [0002] Aneurysms generally refer to intracranial aneurysms, which are localized abnormal enlargements of cerebral arteries, saccular aneurysms are the most common, and others include fusiform aneurysms, dissecting aneurysms, and pseudoaneurysms. Intracranial aneurysms are the most common cause of spontaneous subarachnoid hemorrhage (SAH). [0003] In the prior art, the treatment of aneurysm can be divided into early operation (6-96 hours after SAH) and late operation (more than 10-14 days) according to operation time. 4 to 10 days after SAH, the effect of surgery is poor. Surgical methods include direct surgical clipping of aneurysms and endovascular embolization of aneurysms. Common surgical approaches include clipping, reinforce...

AI Technical Summary

Problems solved by technology

Among them, embolization using microcatheter technology is the most common treatment method at present, but there are some very obvious disadvantages in the operation process. Although some microcatheters can be shaped by vascular models, it is very troublesome to insert and fix them, and It is very inconvenient to insert the microcatheter into the model and not be able to make good use of hot steam for shaping
