Description
Technical field
The present invention relates to field of medical device, in particular to a kind of fixator and fixed system.
Background technology
Dissection of aorta or aneurysm are a kind of clinically very dangerous blood vessel kind diseases, and pole is threatened to patient vitals
Greatly, mainly caused by the reason such as hypertension, artery sclerosis, damage, infection, cause sustainer that limitation expansion occurs, in high pressure
Knurl sample is slowly presented under blood flow impact.Sustainer becomes very fragile by prolonged expansion, vascular wall, is very easy to occur
Rupture, aneurysm will cause and bleed profusely, the title of " bomb " in someone's body, it is big be listed in 10 in American-European countries once rupturing
One of fatal disease.As aging population increase, living standards of the people improve and the continuous improvement of medical level, interlayer and dynamic
The arteries and veins knurl incidence of disease and recall rate are in ascendant trend year by year.At present methods of surgical mainly have open surgery, hybridization operation and
Intracavitary repairing and treating.
Intracavitary repairing and treating is by distal aorta such as Human Femoral Artery otch, will be mounted with the delivery system of overlay film frame
System pushes to diseased region, support expansion isolation lesion artery, rebuilds transmyocardial passageway, so as to reduce aneurysm body pressure, reaches
Therapeutic purposes.Intracavitary reparation, which belongs to, completely intervenes treatment, and abdomen is opened without opening chest, has hand relative to open treatment and hybridization operation
The advantages that art wound is small, and operating time is short, and post-operative recovery is fast.Since the 1990s, repairing and treating in minimally invasive intervention an actor's rendering of an operatic tune
Appearance and development, gradually substituted that open surgery turns into treatment interlayer and aneurysmal operation is preferred.
Inventor has found that traditional treatment interlayer and aneurysmal operation at least have the disadvantage that under study for action：
PCI dissection of aorta and aneurysm still suffer from deficiency, by autologous elastic attachment in human body after support release
Internal blood vessel, the risk of interior leakage and stent migration is occurred under high pressure, the blood flow percussion of high speed.Interior leakage and/or support
Displacement may cause knurl body is postoperative can not reduce or the lasting increase of knurl body occur, intervention operation is not reached expected treatment effect
Fruit even jeopardizes patient vitals；
In the case of having there is interior leakage or stent migration, currently used measure is the proximal location in former support
One piece of support is implanted into again to be remedied.But many deficiencies be present in this processing mode, for example, the support being implanted into again due to
Anchoring condition is bad, lot of unstable factor be present, long-term surgical effect have it is to be assessed, and because branch be present in mount proximal end
The reason for blood vessel, row can not may internally be leaked into without enough grappling sections by new stent by being implanted into one piece of new stent again
Closure.

Embodiment
Referring to Fig. 1, present embodiments provide a kind of fixator 100, for using PCI dissection of aorta and
Aneurysmal Post operation is anchored support and vascular wall 400, effectively prevents that the situation of leakage and stent migration occurs in I types；
In addition, in the case where having occurred leaking in I types, opening position is leaked inside using fixator 100 by stent anchors in vascular wall 400
On remedied and improved.
In the present embodiment, fixator 100 includes transmission arm 120 and at least a three-dimensional spiral fixed arm 110, three-dimensional
The both ends of spiral fixed arm 110 along its length are respectively insertion end 111 and driving end, and insertion end 111 is sophisticated, insertion end
111 can be conical tip, water chestnut cone point (such as Mitsubishi's cone) or wedge shaped tip etc..During grappling, insertion end 111 is utilized
Support overlay film 500 is pierced into successively and vascular wall 400 realizes the grappling of support and vascular wall 400.
Optionally, the outline of three-dimensional spiral fixed arm 110 can be with cylindrical, coniform or round table-like.
Transmission arm 120 is cylindrical shape, and one end of transmission arm 120 is connected with driving end, and transmission arm 120 is consolidated along three-dimensional spiral
The projection in the axis direction of fixed arm 110 is fallen into the region that three-dimensional spiral fixed arm 110 surrounds, and optionally, transmission arm 120 hangs down
Directly set in the axis of three-dimensional spiral fixed arm 110.
Referring to Fig. 2, in other embodiments, three-dimensional spiral fixed arm 110 is provided with two, and two three-dimensional spirals are fixed
Two driving ends of arm 110 connect the both ends of transmission arm 120 respectively, and two three-dimensional spiral fixed arms 110 are coaxially disposed, meanwhile,
Two three-dimensional spiral fixed arms 110 are located at the same side of transmission arm 120, and fixator 100 constitutes double-spiral structure.Double helix knot
The lead angle and pitch of the fixator 100 of structure are bigger, need the angle that rotates smaller during release, and release is more convenient.
In the present embodiment, fixator 100 can pass through machinery by metal materials such as medical stainless steel, cobalt-base alloys, titanium alloys
Be processed into single-screw or double-spiral structure, and be inserted into end 111 processing coning, wedge shape or three (more) prismatics point
Shape, it is easy to puncture support overlay film 500 and vascular wall 400 during release, by the seam between support overlay film 500 and vascular wall 400
Gap closes, and improves the adherence quality of support overlay film 500, while improves the anchorage force between support and vascular wall 400, prevents from propping up
Frame is shifted over.Meanwhile, it is capable to repair the situation for leakage in I types occurred.
It should be noted that fixator 100 can be formed by a strip workpiece bows.
Embodiment
