Abstract
The invention provides a multifunctional fishhook catheter for use in nerve involvement angiography. The multifunctional fishhook catheter comprises a main catheter and a bent catheter arranged on the end part of the main catheter, wherein the connecting ends of the bent catheter and the main catheter have the same hardness; the hardness of the bent catheter is reduced gradually along a direction from the connecting ends to the free end of the bent catheter. The multifunctional fishhook catheter has the advantages of simple structure, easiness in manufacturing and low cost; moreover, deformed vessels can be examined and treated on the premise of not hurting vessel walls.
Description
Technical field
The invention belongs to cerebral angiography and interventional therapy device field, relate in particular to a kind of neural multi-functional fish hook conduit for angiography of getting involved.
Background technology
In cerebral angiography and interventional therapy, because of openings in blood vessels and variation out of shape do not reach check and therapist quite a lot, patient has to abandon check and treatment.
Summary of the invention
The object of the present invention is to provide a kind of neural multi-functional fish hook conduit angiography for of getting involved, be intended to solve in cerebral angiography and interventional therapy and do not reach the problem that checks and treat because of openings in blood vessels and variation out of shape.
The present invention is achieved in that a kind of neural multi-functional fish hook conduit for angiography of getting involved, and comprises main pipe and is located at the curved conductor of described main pipe end; Wherein, the link of described curved conductor and main pipe has same rigidity, and at described link, to curved conductor free end direction, the hardness of described curved conductor diminishes gradually.
Preferably, at described link, between curved conductor free end, described curved conductor is formed by connecting by the conduit of five sections of different hardness, and described different hardness is respectively by regulating conduit inner support thing or sclerosing agent content to control.
Compare and the shortcoming and defect of prior art, the present invention has following beneficial effect: the present invention is simple in structure, is easy to manufacture, and cost is low; The present invention can, blood vessel wall not being caused under damage prerequisite, can easily realize the blood vessel of variation out of shape is checked and treated.
Accompanying drawing explanation
Fig. 1 is the neural structural representation of getting involved multi-functional fish hook conduit one embodiment of angiography of the present invention;
Fig. 2 is that Normal aorta bow and each branch vessel are dissected schematic diagram;
Fig. 3 is the neural using state schematic diagram of the multi-functional fish hook conduit of angiography at variation left common carotid artery blood vessel of getting involved of the present invention.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figures 1 to 3, wherein, the neural structural representation of getting involved multi-functional fish hook conduit one embodiment of angiography of Fig. 1 the present invention; Fig. 2 is that Normal aorta bow and each branch vessel are dissected schematic diagram; Fig. 3 is the neural using state schematic diagram of the multi-functional fish hook conduit of angiography at variation left common carotid artery blood vessel of getting involved of the present invention.
A kind of neural multi-functional fish hook conduit for angiography of getting involved, comprises main pipe 1 and is located at the curved conductor 2 of described main pipe 1 end; Wherein, described curved conductor 2 has same rigidity with the link of main pipe 1, and at described link, to curved conductor 2 free end directions, the hardness of described curved conductor 2 diminishes gradually.
In embodiments of the present invention, more specifically, at described link, between curved conductor 2 free ends, described curved conductor 2 is formed by connecting by the conduit of five sections of different hardness, and described different hardness is respectively by regulating conduit inner support thing or sclerosing agent content to control.
In actual application of the present invention, fish hook conduit of the present invention as shown in Figure 3, easily para-position is to the left common carotid artery opening of variation, select to left common carotid artery and the simple blunt difficulty of multifunctional single curved conductor Chi is super, fish hook conduit can easily be realized super choosing, and because of bending conduit free end relatively soft, can deeply under the super situation of selecting, select to blood vessel far-end is super with seal wire 3 at seal wire 3, and be unlikely to rebound out, and blood vessel wall damaging dropped to minimum, in cerebral angiography and interventional therapy, can the blood vessel of variation out of shape be checked and be treated.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
Claims (2)
1. nerve is got involved a multi-functional fish hook conduit for angiography, it is characterized in that, comprises main pipe and is located at the curved conductor of described main pipe end; Wherein, the link of described curved conductor and main pipe has same rigidity, and at described link, to curved conductor free end direction, the hardness of described curved conductor diminishes gradually.
2. the neural multi-functional fish hook conduit for angiography of getting involved as claimed in claim 1, it is characterized in that, at described link between curved conductor free end, described curved conductor is formed by connecting by the conduit of five sections of different hardness, and described different hardness is respectively by regulating conduit inner support thing or sclerosing agent content to control.
