Abstract
The utility model relates to a conical balloon dilatation catheter. The conical balloon dilatation catheter comprises a balloon body and catheters; the balloon body has a conical structure; the front and rear ends of the balloon body are connected with a conical section body 1 and a conical section body 2 which are matched with each other; and the conical section body 1 and the conical section body 2 are connected with the catheters respectively. The provided conical balloon dilatation catheter has the advantages that the provided conical balloon dilatation catheter can be used for a tapered vessel and high in penetration performance in the tapered vessel; the damage to the vessel is reduced; and the phenomenon of tearing is avoided.
Description
Technical field
This utility model relates to a kind of conical saccule dilating catheter.
Background technology
Progress along with science and technology, the particularly development of biomedical engineering, people have been incorporated into medical domain to advanced person's in the present age technology, method with engineering solves the medical science problem, for the diseases such as coronary stricture, cerebral vessels embolism and hemangioma are had better medical procedure, so innovated PTCA catheter technology, i.e. percutaneous puncture arteria coronaria foley's tube technology.Existing sacculus dilating catheter, its sacculus partly is generally cylindrical structural, but the blood vessel on the human body is not all to be cylindrical, for example, the blood vessel of inferior genicular artery is exactly taper from coarse to fine, so when angiostenosis needed balloon expandable, columniform sacculus can cause the overdistension of blood vessel, even the phenomenon that occurs tearing.
The utility model content
The purpose of this utility model provides a kind of conical saccule dilating catheter, overcomes when using in the existing product to cause overdistension, even the deficiency of vascular tear.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of conical saccule dilating catheter comprises sacculus body and conduit, and described sacculus body is conical structure, and sacculus body front and back ends is connected with respectively cone segment body one and the cone segment body two that matches, and cone segment body one and cone segment body two are connected with respectively conduit.
Further, the diameter of described sacculus body front end is greater than the diameter of sacculus body rear end.
The beneficial effects of the utility model are: a kind of conical saccule dilating catheter that this utility model provides, can use for the taper blood vessel, in the taper blood vessel to pass through performance good, reduced the damage to blood vessel, avoid the generation of the phenomenon of tearing.
Description of drawings
The below is described in further detail this utility model with reference to the accompanying drawings.
Fig. 1 is the structural representation of the described a kind of conical saccule dilating catheter of this utility model embodiment;
Fig. 2 is the structural representation of existing sacculus dilating catheter.
Among the figure:
1, sacculus body; 2, conduit; 3, cone segment body one; 4, cone segment body two.
The specific embodiment
As shown in Figure 1, the described a kind of conical saccule dilating catheter of this utility model embodiment, comprise sacculus body 1 and conduit 2, described sacculus body 1 is conical structure, sacculus body 1 front and back ends is connected with respectively cone segment body 1 and the cone segment body 24 that matches, and cone segment body 1 and cone segment body 24 are connected with respectively conduit 2; The diameter of described sacculus body 1 front end is greater than the diameter of sacculus body 1 rear end.
Sacculus body 1, cone segment body 1, cone segment body 24 and conduit 2 are structure as a whole, during use, the conduit 2 of cone segment body one 3 one ends is introduced into blood vessel, then sacculus body 1 integral body is expanded by blood vessel again, wherein, the inclined-plane of sacculus body 1 conical structure plays good cushioning effect, has avoided existing cylindrical balloon dilating catheter (as shown in Figure 2), cause the overextending of blood vessel, even the phenomenon of tearing occurs.
This utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
