Abstract
The utility model discloses a cone passibility blood vessel dilatation balloon which comprises an inflating air bag, a catheter, an inflating pipe and a guide wire. The balloon is communicated with the inflating pipe; the inflating pipe is positioned on the side wall inside the catheter; the ballon is positioned on the catheter; one guide wire is arranged inside the catheter; the inflating pipe is integrated with the catheter into one whole body; a plurality of longitudinal through pipe cavities for enabling blood flow to pass through are arranged around the catheter; and the balloon is of a cone shape of which the diameter is gradually increased from the far end to the near end. According to the utility model, by arranging a plurality of longitudinal through pipe cavities on the balloon, blood flow is guaranteed to still pass through a dilated blood vessel to be supplied for the visceral organs at the far end when a dilation narrow region is inflated, so that the ischemia time of the visceral organs at the far end is reduced and the operation risk is reduced; and by setting the balloon into the cone shape of which the diameter is gradually increased from the far end to the near end, the problem of possible inconsistency of the dilatation degrees of the blood vessel at the far end and the blood vessel at the near end when a standard balloon is used can be solved.
Description
Technical field
This utility model relates to a kind of passability Angiectasis sacculus, particularly a kind of improved taper passability Angiectasis sacculus.
Background technology
The Angiectasis sacculus active section of standard is the tubular body of even thickness, in the interventional therapy operation of long and narrow pathological changes, conventionally adopted in the past two or more supports to overlap to carry out angioplasty, there is now a kind of overlength support, along with the increase of stent length, the length of balloon of transfer gantry also needs continuous lengthening.From anatomy, along the direction of blood flow, the diameter of blood vessel is constantly diminishing, if adopt the sacculus of normal structure, finishes operation when near-end is just expanded in operation, and far-end may overextend, and distal vessels is impaired, easily occurs postoperative again narrow; If distal dilation finishes operation just time, near-end may fully not expanded, and support is completely not adherent, easily causes thrombosis and blood vessel again narrow, even inaccessible.In addition; when dilating sacculus because sacculus moment is coronary artery total blockage; the myocardium moment ischemia that causes region that this arterial distal is arranged, may occur that quiver in arrhythmia or chamber, cardiac arrest threat to life, and patient may feel that discomfort uncomfortable in chest, agitation or mind disappear.
Utility model content
For above-mentioned problems of the prior art, this utility model aims to provide a kind of taper passability Angiectasis sacculus, this utility model can solve that normal structure sacculus easily occurs " when near-end is just expanded in operation, finish operation; far-end may overextend; distal vessels is impaired, easily occurs postoperative again narrow; If distal dilation finishes operation just time, near-end may fully not expanded, and support is completely not adherent, easily causes thrombosis and blood vessel again narrow, even inaccessible " problem, can guarantee to still have supply of blood flow far-end internal organs simultaneously when inflatable dilatation narrow zone.
In order to achieve the above object, this utility model is taked following technical scheme:
A kind of taper passability Angiectasis sacculus, comprise aerating gasbag, conduit, gas tube, seal wire, described sacculus is connected with gas tube, gas tube is positioned at catheter interior sidewall, sacculus is positioned on conduit, catheter interior is provided with a seal wire, gas tube and conduit are in aggregates, on described sacculus, conduit around, being provided with the straight-through tube chamber of a plurality of stringers passes through for blood flow, when inflatable dilatation narrow zone, by blood vessel dilating intracavity, still had blood flow to pass through, supply far-end internal organs, reduced far-end internal organs Ischemia Time, and can make the more abundant of narrow section expansion, facilitate the measurement of pressure measurement and blood oxygen saturation in art, reduce operation risk.
The taper of described sacculus for increasing gradually to balloon proximal diameter from sacculus far-end, described taper sacculus comprises the tapering at active section and active section two ends, described active section is taper type, and described tapering comprises far-end tapering and near-end tapering, and described two taperings and each shape of active section have angle.
Angle between described sacculus active section and far-end tapering is 150 ℃-170 ℃, and the angle between active section and near-end tapering is 135 ℃-160 ℃.
Preferably the junction in this utility model sacculus active section and tapering is arc, and this arcuate structure can reduce the damage to blood vessel wall.
The angle being preferably between this utility model sacculus active section and far-end tapering is 160 ℃, and the angle between active section and near-end tapering is 150 ℃.
The beneficial effects of the utility model are: by be provided with the straight-through tube chamber of a plurality of stringers on sacculus, moment blood flow for balloon expandable passes through, supply of blood flow far-end internal organs have been guaranteed like this to still have when inflatable dilatation narrow zone, reduced far-end internal organs Ischemia Time, and can make the more abundant of narrow section expansion, facilitate the measurement of pressure measurement and blood oxygen saturation in art, reduce operation risk; From anatomy, along the direction of blood flow, the diameter of blood vessel is constantly diminishing, if adopt the sacculus of normal structure, finishes operation when near-end is just expanded in operation, and far-end may overextend, and distal vessels is impaired, easily occurs postoperative again narrow; If distal dilation finishes operation just time, near-end may fully not expanded, and support is completely not adherent, easily causes thrombosis and blood vessel again narrow, even inaccessible.So by sacculus active section is made as to cone, can effectively address this problem when the long and narrow pathological changes for the treatment of.By tapering and active section junction are made as to arc, can reduce the damage of sacculus to blood vessel wall.
