Abstract
The utility model relates to a medical artificial blood vessel, in particular to a thin dacron-made artificial blood vessel with interval lines, wherein, the dacron-made artificial blood vessel comprises a vessel wall of the dacron-made artificial blood vessel, and the wall thickness thereof ranges from 0.07 to 0.25mm. The thin dacron-made artificial blood vessel is characterized in that lines are formed on the vessel wall of the dacron-made artificial blood vessel at intervals in the axial direction. The thin dacron-made artificial blood vessel mainly solves the technical problem that lines are not uniform after the lines are made continuously during the prior process for manufacturing a thin satin artificial blood vessel because the small thickness of dacron-made blood vessel material so as to cause the disorganized lines, and can ensure that the satin blood vessel can be stretched evenly when in use.
Description
Technical field
This utility model relates to medical treatment and goes up the artificial blood vessel of using, and especially a kind of thin type is made the stricture of vagina dacron-made artificial blood vessel at interval.
Background technology
Medical circle can be treated the human common disease of the overwhelming majority, and in surgical operation, the application of the property implanted medical material is very extensive.Multiple implantation medical material has been obtained the good medical treatment effect clinically, and greatly degree alleviates patient's misery.The artificial blood vessel of prior art generally is to adopt woven method weaving to form, and domestic existing woven blood vessel's organizational structure is broadly divided into tube wall fiber alignment two kinds of fluffy satin weaves of plain weave and fibrous structure closely.The former comprises woven real silk artificial blood vessel/weaving polyester artificial vascular and real silk and the interlacing artificial blood vessel of terylene, and the latter then is woven lint dacron-made artificial blood vessel.Above-mentioned multiple artificial blood vessel all can reach general technique effect.
Yet the tube wall of plain weave artificial blood vessel is organized because of it and is too closely made permeability extremely low, though and the tube wall oozing of blood of low permeability tube wall when helping avoiding performing the operation, but be difficult to the tissue of growing into, inaccessible perfect organization healing, therefore degeneration and foreign body taking place after transplanting easily repel, tube wall calcification, the contraction of body cicatrix and tube chamber for example can occur and block.The high-permeability of satin weave artificial blood vessel and tissue after helping transplanting is grown into, and can form and the similar neointima of normal blood vessels inner membrance at the tube wall inner face.But,, must handle and can use through pre-blood coagulation earlier if under the extracorporeal circulation of whole body heparinization, use.Can make the process of operation loaded down with trivial details like this, comparatively inconvenience in the operation process of racing against time.
In view of the foregoing, the artificial blood vessel with satin weave is further promoted the use of, and discloses a kind of artificial blood vessel with satin weave as Chinese invention patent application (CN1565394).This product makes the long lint shape fluffy fiber in the former satin weave change into the fibre structure of short bowing, tube wall oozing of blood in the time of can both helping like this controlling operation, what help again organizing grows into and heals, and helps again carrying out and operation stitching simultaneously.Owing to change the fiber spreading that the fibre structure of the bowing in the satin weave does not have satin weave to have high span like that, so its tube wall oozing of blood can not be big.Thus, the artificial blood vessel that as seen has a satin weave is compared with the former and is had certain advantage.
But, we find because the thickness thin excessively (thickness is 0.07-0.25mm) of terylene vascular grafts in to the manufacture process of thin type satin weave artificial blood vessel, lines behind the therefore continuous satin weave is inhomogeneous, produce the situation of lines disorder, influenced yield rate and the result of use that has influenced product in the production on the contrary.
The utility model content
The purpose of this utility model is to provide a kind of thin type to make the stricture of vagina dacron-made artificial blood vessel at interval, mainly solve existing thin excessively to the thickness owing to the terylene vascular grafts in the manufacture process of thin type satin weave artificial blood vessel, lines behind the satin weave is inhomogeneous continuously, produced the technical problem of lines disorder, the satin weave blood vessel in can guaranteeing to use stretches evenly.
For addressing the above problem, this utility model is achieved in that
A kind of thin type is made the stricture of vagina dacron-made artificial blood vessel at interval, and it comprises that wall thickness is the terylene vascular wall of 0.07-0.25mm; It is characterized in that: the interval satin of axially going up of this vascular wall is provided with lines.
Described thin type is made the stricture of vagina dacron-made artificial blood vessel at interval, it is characterized in that: the spacing d1 of lines is 0.5-2mm in each section lines, and the length d 2 between lines is 10-50mm.
Adopt said structure, the utlity model has following advantage:
The interval satin weave structure that this utility model adopts except keeping the advantage of original satin weave artificial blood vessel, also helps when making thin type and making the stricture of vagina blood vessel, guarantee blood vessel initial, termination place lines is not disorderly, and product is in use stretched evenly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As Fig. 1, the utility model discloses a kind of thin type and make the stricture of vagina dacron-made artificial blood vessel at interval, it comprises that wall thickness is the terylene vascular wall of 0.07-0.25mm; It is characterized in that: the interval satin of axially going up of this vascular wall is provided with lines.The spacing d1 of lines is 0.5-2mm in each section lines, and the length d 2 between lines is 10-50mm.。
The interval satin weave structure that this utility model adopts except keeping the advantage of original satin weave artificial blood vessel, also helps when making thin type and making the stricture of vagina blood vessel, guarantee blood vessel initial, termination place lines is not disorderly, and product is in use stretched evenly.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of this utility model claim change and modification, all should be technology category of the present utility model.
Claims (2)
1, a kind of thin type is made the stricture of vagina dacron-made artificial blood vessel at interval, and it comprises that wall thickness is the terylene vascular wall of 0.07-0.25mm; It is characterized in that: the interval satin of axially going up of this vascular wall is provided with lines.
2, thin type according to claim 1 is made the stricture of vagina dacron-made artificial blood vessel at interval, it is characterized in that: the spacing d1 of lines is 0.5-2mm in each section lines, and the length d 2 between lines is 10-50mm.
