Description
Technical field
This utility model relates to technical field of medical instruments, specifically, is a kind of intracranial aneurysm neck reconstructing device.
Background technology
Intracranial aneurysm is the encephalic angioma sample projection because local vascular abnormal change produces, it is the cerebrovascular disease of a kind of high pathogenicity rate and high fatality rate, be the main cause causing subarachnoid hemorrhage, the intracranial aneurysm mortality rate broken is up to 51%, and the disability rate of existent is close to 50%.It is two kinds of major ways for the treatment of of intracranial aneurysm that surgical clamp is closed with intravascular Interventional Treatment.Along with the development that intervention apparatus is swift and violent, intracranial aneurysm interventional therapy, owing to having Wicresoft, safety, the advantage such as effective, has become the clinical treatment of a lot of hospitals first-selection at present.
The principle of interventional therapy is clogged by mechanicalness, change local hemodynamic studies factor, secondary thrombus is formed, having developed various embolization device is in the world used for the treatment of aneurysm at present, as turn, is directed in aneurysm by intubation intervention, fill aneurysmal space, form thrombosis at short notice, reduce blood directly to the impact of aneurysmal arm, thus prevent aneurysm rupture.
But aneurysmally to come in every shape, use turn filling not exclusively, cause aneurysm to be led to again, excessively filling causes aneurysm rupture, and Aneurysmal neck given prominence to by turn affects parent artery blood flow.Along with the development of interventional technique, the appearance of support secondary spring circle thromboembolism entocranial artery technology, is released in tumor neck place by support, retracting spring circle in aneurysm cavity, props up in the arteries be placed in aneurysm, turn can be stoped to give prominence to aneurysm.
Chinese patent literature CN201320036422.5, at on 01 24th, 2013 applying date, patent name is " intracranial self-expanding stage peritoneum braided support ", disclose a kind of intracranial self-expanding stage peritoneum braided support, comprise braided support, it is characterized in that being provided with support overlay film, described braided support be B alloy wire two ends respectively by one end to the other end by axis and the mutual crossed loops of radial direction around and the net tubular bracket of working out that circulates, cylindrical in the middle of establishment support, two ends flare, make to form closed-loop structure between the mesh of braided support and mesh, add the radial support power at two ends, the B alloy wire of the both ends of the surface of braided support is curved, avoid puncturing intracranial vessel, the cylindrical surface of braided support is covered with support peritoneum, blood flow is avoided to impact intracranial angioma neck, avoid the filling turn of aneurysm tumor intracavity outstanding simultaneously and block arteries, reach and accelerate inner membrance growth rate, make the effect of aneurysm complete obturation quickly.
This overlay film frame is applicable to the aneurysm for the treatment of huge, the wide neck of intracranial or fusiformis, but is difficult to send into intracranial target for the parent artery of some furcations or the opening parent artery close to bifurcated.
Reconstructing blood vessel device is one of focus of current intracranial aneurysm apparatus research and development, in aneurysm, the forming part of tumor neck is the position that parent artery is constructed defect and local hemodynamic conflict and concentrated the most, therefore, fine and close filling tumor neck, recovers the integrity of local parent artery, be reparation parent artery, treat aneurysmal prerequisite and basis, but fine and close filling tumor neck selects turn usually in prior art, its Coil embolization is very fine and close, easily causes aneurysm rupture; In addition, aneurysm is the result of parent artery pathological changes, repairs parent artery and contributes to reducing aneurysm recurrence.
In sum, need a kind of promotion thrombosis badly, compactness filling tumor neck, slow down blood flow velocity in aneurysm, hemodynamics in aneurysm is changed, reduces regional flow to the impact of tumor wall, reinvent parent artery, strengthen, repair the Aneurysmal neck reconstructing device of local parent artery, and yet there are no report about this Aneurysmal neck reconstructing device.
Summary of the invention
The purpose of this utility model is for deficiency of the prior art, there is provided a kind of and promote thrombosis, compactness filling tumor neck, slow down blood flow velocity in aneurysm, hemodynamics in aneurysm is changed, reduce regional flow to the impact of tumor wall, reinvent parent artery, strengthen, repair the Aneurysmal neck reconstructing device of local parent artery.
For achieving the above object, the technical scheme that this utility model is taked is:
A kind of intracranial aneurysm neck reconstructing device, described tumor neck reconstructing device comprises reconstructing device body, seal wire, outer sheath; Described reconstructing device body is by having the tinsel of shape memory effect or having elastomeric macromolecule silk material and be woven into mesh, and its mesh form is Pedicellus et Pericarpium Trapae shape; Described mesh is that waveform is wound around; Be hollow out stereochemical structure under described reconstructing device body deployed condition; Described reconstructing device body distal end is provided with head end developing block, and described reconstructing device body middle-end is provided with middle-end developing block; Described reconstructing device body distal end ovalize, the near-end of described reconstructing device body draws in downwards and is fixed on seal wire; Described seal wire is positioned at outer sheath; Described seal wire and reconstructing device body junction are provided with frees a little; The other end of described seal wire connects reliever.
