Description
Technical field
The present invention relates to the medical apparatus and instruments of cardiovascular technical field, particularly to a kind of cardiovascular expansion device improving the blood flow direction for expanding cardiovascular narrow zone.
Background technology
Existing vessel dilator pushed enter the mode taked of blood vessel be dilator to be inserted in one stay tube, after a stay tube gos deep in blood vessel, utilize a push rod to be pushed blood vessel by dilator in a stay tube.Existing problems: one is that dilator is flexible, are expansible after departing from support pipe port, and thrust subsequently is easily caused dilator and blood vessel friction, makes blood vessel impaired；Two is to prop up the internal-and external diameter of stay tube the most greatly, not easily passs through, easily block blood vessel after running into narrow blood vessel, and it is the most difficult that dilator departs from a stay tube.
Summary of the invention
It is an object of the invention to generally there is structure problem complicated, unhandy for existing cardiovascular expansion device, it is provided that a kind of cardiovascular expansion device that can regulate.
For achieving the above object, adopt the following technical scheme that a kind of cardiovascular expansion device, include handle, bar portion, radial dilatation mechanism and guide head successively, wherein, described radial dilatation mechanism includes an air bag being arranged on front end, bar portion, is enclosed with one layer of radial dilatation pipe compressed outside air bag, wraps up one layer of easy absorption theca externa in the outside of radial dilatation pipe, further, the side at easy absorption theca externa is provided with and easily tears seam；It is provided with the trachea connected with air bag in bar portion, and is arranged on the gas-filled switching tube of handle position.The seam that easily tears easily absorbing theca externa can be forced to split by inflation in air bag, so that the radial dilatation pipe Automatic-expanding compressed, be fitted in blood vessel and reach to support purpose.Radially it is provided with interior lacing wire in described air bag inwall both sides, thus air bag can be retrained and keep even inflation.Being provided with circular membrane groove outside described air bag, described radial dilatation pipe box is loaded in circular membrane groove, and described easy absorption theca externa is positioned at circular membrane groove.
A kind of cardiovascular expansion device, include handle, bar portion, radial dilatation mechanism and guide head successively, wherein, described radial dilatation mechanism includes a stay tube being arranged on front end, bar portion, one layer of radial dilatation pipe having one layer to be compressed is wrapped up outside a stay tube, one layer of easy absorption theca externa is wrapped up in the outside of radial dilatation pipe, and, it is provided with in the side easily absorbing theca externa and easily tears seam；The described seam that easily tears easily tears seam for the formula of taking out stitches, or easily tears seam for zip mode；Side in described bar portion is axially disposed wire casing, described in formula of taking out stitches easily tear seam or zip mode easily tears the bracing wire of seam and is positioned in wire casing, the end of bracing wire is positioned at handle position.Being provided with circular membrane groove outside described stay tube, described radial dilatation pipe box is loaded in circular membrane groove, and described easy absorption theca externa is positioned at circular membrane groove.Described radial dilatation pipe is network structure, is connected by the shell fragment of fold between adjoining cells, and keeps expanding prestressing force.Described radial dilatation pipe is the compressed pipe of fold, and keeps expanding prestressing force, is provided with through hole on compressed pipe.Bar portion can be a kind of elongated flexible material, under guide head effect can along blood vessel trend adjustment direction voluntarily.
Beneficial effect: after the present invention improves, support bar is thinner, flexible, Intravascular migration can be freed from, vasoinert normal blood transfusion function, easily tear seam at correct position by control to make easily to absorb outer layer open, make the radial dilatation pipe of inner side launch, reach the effect of original place radial development support blood vessels inwall.Radial expansion pipe has radial development prestressing force after being compressed, after easily tearing seam cracking, radial expansion pipe gets final product Automatic-expanding.The most easily tearing seam can make it ftracture by air pressure, it is also possible to by slide fastener or formula of taking out stitches, control to make it ftracture by stay cord.Radial expansion pipe is hidden in front end, bar portion after being compressed, do not affect the retreat operation in bar portion.Easily absorbing outer layer can be a kind of protein film, it is easy to absorb.The radial expansion pipe of compression is sent to destination by tiny rod member by the present invention, can exit rod member be very easy in destination's original place radial development, and blood vessel will not be caused friction by whole operating process.It is simple and reasonable, is especially advantageous for promotion and implementation.
