Description
Technical field
The invention belongs to the field of medical instrument technology, in particular to a kind of blood vessel that can be used for the expansion of vascular occlusion position
Patch cutter device.
Background technique
Interventional therapy refer to the image documentation equipments such as digital subtraction angiography machine, CT, ultrasound and magnetic resonance guidance and
Under monitoring, using puncture needle, conduit and other interposers materials, by human body natural duct or small wound by specific instrument
Import the general name that human lesion position carries out a series of technologies of minimally-invasive treatment.Vascular plaque is deposited in by metabolism of lipid and cholesterol
In arteries, atherosclerotic plaque is formed, arteriarctia is caused to be blocked.The symptom of atherosclerosis depends primarily on
The degree of ischemia of vascular lesion and afflicted organ.Atherosclerosis of aorta is often without specific symptom；Coronary atherosclerosis person,
If caliber is narrow up to 75% or more, angina pectoris, myocardial infarction, arrhythmia cordis, or even sudden death can occur；Cerebral atherosclerosis
It can cause cerebral ischemia, encephalatrophy, or cause rupture of blood vessel in brain bleeding；Renal artery atherosclerosis often causes the high blood of enuresis nocturna, intractable
Pressure, serious person can have renal insufficiency；Superior mesenteric atherosclerosis can behave as abdominal pain, indigestion, constipation etc. after heavy meal,
Intestinal wall necrosis can cause the symptoms such as hematochezia, paralytic ileus when serious；Lower limb atherosclerosis causes lumen of vessels seriously narrow
Narrow person may occur in which that intermittent claudication, pulsation of foot dorsal artery disappear, and even gangrene can occur for serious person.
Using the means of interventional therapy, the blood vessel that sacculus dilating catheter merging vascular plaque position pressurization expansion is blocked,
Making restoration of blood flow is the common method for treating arteriarctia obstruction.The mechanism of action of common balloon expandable vascular plaque is by right
Balloon wall, which applies pressure, makes balloon wall and vascular plaque contact action, tears vascular plaque using the pressure of application, makes blood flow
Restore.After usual balloon expandable vascular plaque, bracket can be placed in former plaque location to prevent restenosis.
Carrying out vascular plaque expansion using common sacculus leads to blood vessel spot since expansion pressure stepless action is in target vessel
The tearing of block inhomogeneities, easily causes patch to fall；In addition for some more serious calcifications and fibrosis lesion, common ball
Capsule is difficult to expand patch.If sacculus cannot expand vascular plaque well, it is adherent bad to will lead to bracket, and then can lead
Target vessel restenosis rate and the incidence of Intravascular Thrombus is caused to improve.
It is difficult to the situation expanded for common sacculus, mainly uses Cutting balloon conduit to carry out in blood vessel intervention operation at present
Surgical procedure mainly has following several structures.One is Cutting balloon, and structure feature is the multiple cuttings of balloon surface adhesion
Blade contacts cutting blade by full dilating sacculus and cuts athero- calcification lesion.This its defect of Cutting balloon conduit
It is that its outside dimension is larger, is not easily accessible serious Occlusion；Multiple cutting blades outside sacculus, be easy to cause injury of blood vessel,
Postoperative complication is caused to lead to risk and possible threat to life.Secondly being single or multiple seal wire Cutting balloons, structure feature
To be fixed with a seal wire outside sacculus, two seal wires are formed by sacculus outer surface using guiding wire, pass through full expansion ball
Capsule contacts seal wire and tears athero- calcification lesion.This Cutting balloon conduit has a disadvantage in that its seal wire needs outside by sacculus
Surface, academic title length of the seal wire inside foley's tube greatly reduce, substantially reduce foley's tube along seal wire tracking ability, lead
It causes conduit lesion passability to substantially reduce, serious Occlusion should not be entered；Since seal wire is completely fixed in balloon distal and close
End, during balloon expandable process, banana deformation easily occurs for sacculus, causes lesion discontinuity；This structural conductor,
Its cutting wire is coated on sacculus both ends, and cutting wire easily collapses abjection in use, leads to tubes fail and destroys normal blood
Pipe.Thirdly structure feature is to be fixed with a ring support outside sacculus to be to have ring support class helical structure outside sacculus,
Make bracket contact vascular plaque using the full expansion of sacculus and tears athero- calcification lesion.This conduit has a disadvantage in that its annular
Bracket bent stress is larger, not easily passs through tortuous blood vessel, and operation is caused to be unable to complete.In addition three of the above structure is not cut
Silk position indicating ring, under X-ray can not visible cutting wire position, can only by sacculus developing ring position guess cleavage
It sets and carries out operation expansion, also result in the complication of injury normal blood vessels.
It is therefore desirable to have a kind of vascular plaque cutter device, can overcome the outside dimension of traditional Cutting balloon big, it is not easy to lead to
Cross serious Occlusion, cutting wire easily collapses de-, and cutting wire can not determine the prior art problems such as specific location, and retain common ball
The basic structure and application method of capsule dilating catheter keep surgical operation convenient.
