Description
Technical field
The present invention relates to technical field of medical instruments, it is specifically related to a kind of vascular inner body finishing device, this finishing device is particularly well-suited in intravascular intervention operation, the surgical material displacements such as turn come off and block the situation of normal blood vessels, can safely and easily take out this type of vascular inner body, it is to avoid blood vessel blockage causes cerebral infarction to wait indefinitely situation.
Background technology
Intracranial aneurysm is a kind of common cerebrovascular, has high mortality rate and disability rate.The therapeutic modality of intracranial aneurysm has two kinds at present, i.e. surgical clamp is closed or endovascular intervention.After electrolysis turn invention in 1991, the latter has become the important method for the treatment of intracranial aneurysm the most.Have become as the first-selected Therapeutic Method of developed country most of aneurysm patients such as America and Europe at present, be the most quickly developed universal in China.
Although interventional embolization intracranial aneurysm is short with its Wicresoft, hospital stays, it is fast as characteristic to recover, but the surgical material displacements such as turn come off and block the situation of normal blood vessels and occur the most once in a while, thus bring great risk to operation.Once occur, the most easily cause intra-arterial to form thrombosis even Parent artery occlusion and cause cerebral infarction.
It has been reported that mainly have four types such as micro-lasso trick, micro-clamp, helical bottle opener shape catching device, shelf-like catching device for the apparatus type fishing for the vascular inner bodies such as turn that come off:
The design of the most micro-lasso trick is similar to lasso, lasso trick i.e. opens set cringle after trocar sheath stretches out, after target enters set cringle, tightening sleeve cringle can arrest target, but this set cringle is difficult to fully open in tiny intracranial distal vessels, if the foreign body of displacement is reunited intensive, then it is difficult to be entangled, fishes for bigger occasionality；
2. micro-clamp design is mainly used in the big vascular inner body in periphery and fishes for, the most also foreign body is fished in being used for, medium-sized artery big at intracranial, but the Machine Design of its complexity causes its end stiff, bigger to fragile cerebrovascular trauma, and need larger space fully to open, it is not suitable for the cerebrovascular that end is very thin equally；
3. helical bottle opener shape catching device design principle is similar to Corkscrew, main purpose is to fish for the thrombosis in tremulous pulse, being applicable only to the regions such as bigger internal carotid artery, middle cerebral artery near-end in the brain, its end is the most stiff, is not particularly suited for the cerebrovascular that far-end is tiny；
4. shelf-like catching device originates from endovascular stent design, it is applied to fishing for vascular inner body because it is similar to trawlnet shape, but just as trawlnet is to the infringement greatly of riverbed ecosystem, support is the vascular endothelial cell of inevitably damaging delicate when Ink vessel transfusing drags, and even directly results in vasospasm inaccessible.And, its end Machine Design is complicated and stiff, poor by property, needs larger space to operate, if misoperation is once push less tremulous pulse by foreign bodies such as turns, will be unable to fish for, causes permanent injury.
In recent years, interventional therapy aneurysm surgery quantity rapid development, the come off quantity of event of the surgical material such as turn of generation also gradually increases accordingly, but from current medical skill, there is no and preferably fish for apparatus.
Summary of the invention
For above-mentioned technical problem, it is desirable to provide a kind of vascular inner body finishing device, this capturing device and capturing method can safely and easily take out the vascular inner body of the surgical material that displacement comes off etc, it is to avoid blood vessel blockage causes cerebral infarction to wait indefinitely situation.
The present invention solves the technical scheme of problem: a kind of vascular inner body finishing device, it is made up of A micro-wire and B micro-wire, wherein A micro-wire band is magnetic, and B micro-wire has ferromagnetism but itself is for non magnetic, A micro-wire and B micro-wire is supporting becomes finishing device.
In technique scheme, the magnetic position of described A micro-wire band is at its end, or near end but do not arrive one section of region of end, the most only need to ensure A micro-wire end or be magnetic by the regional area band at subterminal position, it is possible to attracting B micro-wire.
In technique scheme, described A micro-wire end or near end but not arrive stub area be magnetized metal material, or itself is containing magnetisable material, or is magnetisable coating.
In technique scheme, the nickel-containing alloys guidewire material that B micro-wire material can preferably be commonly used.
Accordingly, the present invention also provides for utilizing above-mentioned vascular inner body finishing device to carry out the method fished for, and comprises the steps:
A) at Ink vessel transfusing, A micro-wire is passed the foreign body gap of displacement；
B) B micro-wire is passed other gap of the foreign body of displacement；
C) magnetic A micro-wire end is made to attract B micro-wire end and rotate two micro-wires simultaneously so that it is the foreign body of displacement to be wound around loop and lives；
D) two micro-wires are exited simultaneously, foreign body is hauled out from Ink vessel transfusing.
The remarkable result of the present invention is: owing to equipment used is micro-wire, so it more can pass narrow regions and vascular inner body smoothly；Safety based on micro-wire and ease for operation, make a seal wire distal portion band be magnetic, and with another root seal wire with the use of, the foreign body such as turn fishing for Ink vessel transfusing displacement that can be easy, safe, reduces the uncertainty of commonsense method operation；Further, owing to seal wire is thin and soft, the infringement to blood vessel wall is alleviated than traditional method.
Simultaneously as two seal wires are wound around after rotating, vascular inner body can be captured firmly, the good stability of its operation, relatively low to the operation level requirement of doctor, it is more suitable for penetration and promotion, it is adaptable to the minute blood vessel that all interventions operation can arrive.
