Specific implementation mode
In order to enable those skilled in the art to better understand the solution of the present invention, below in conjunction in the embodiment of the present invention
Attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only
The embodiment of a part of the invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people
The every other embodiment that member is obtained without making creative work should all belong to the model that the present invention protects
It encloses.
Reverse seal wire guide device according to the ... of the embodiment of the present invention, as depicted in figs. 1 and 2, including seal wire poling 10, guiding
Sacculus 20 and media lines 30；Guiding sacculus 20 is arranged in the end of seal wire poling 10；Media lines 30 connect with seal wire poling 10
It connects and is connected to the inner cavity of guiding sacculus 20, media lines 30 are used into guiding sacculus 20 inject fluid media (medium) so that guide ball
Capsule 20 expands or will guide the fluid media (medium) in sacculus 20 and extracts out so that guiding sacculus is shunk.
Using the reverse seal wire guide device of technical solution of the present invention, including seal wire poling 10, guiding sacculus 20 and medium
Conduit 30；Guiding sacculus 20 is arranged in the end of seal wire poling 10；Media lines 30 are connect with seal wire poling 10 and and guide ball
The inner cavity connection of capsule 20, media lines 30 are used for the injection fluid media (medium) into guiding sacculus 20 so that guiding sacculus 20 expands or will
The fluid media (medium) in sacculus 20 is guided to extract out so that guiding sacculus 20 is shunk.To in the course of surgery, by by reverse seal wire
Poling 10 passes through positive guiding catheter and penetrates internal blood vessel, and into guiding sacculus 20, injection fluid media (medium) keeps guiding sacculus 20 swollen
Gap between seal wire poling 10 and blood vessel is blocked after swollen, consequently facilitating reverse seal wire first penetrates seal wire poling 10, then by leading
Silk poling 10 guides reverse seal wire to enter positive guiding catheter, completes penetrating for reverse seal wire.Whole process is efficient and convenient, effectively
Solve the problems, such as that seal wire in the prior art is difficult to penetrate positive guiding catheter.Improve the efficiency and quality of operation.
When it is implemented, further, the front port of media lines 30 passes through the rear end face and guide ball that guide sacculus 20
The inner cavity of capsule 20 is connected to, and the rear port of media lines 30 is provided with connection end 31, and connection end 31 is used to connect with injection device
It connects.The front end of media lines 30 is close to one end of guiding sacculus 20, and the follower head of media lines 30 is far from guiding sacculus
20 one end.Optionally, injection device can be manually syringe, or syringe pump etc..In order to ensure the peace of operation
Entirely, avoid guiding sacculus 20 that rupture occurs and causes danger, further, fluid media (medium) is that physiological saline and contrast agent mix
Liquid.The requirement for making guiding sacculus 20 expand can both have been met by saline injection, can also avoid sending out in guiding sacculus 20
Surgical risks are caused when raw rupture.Meanwhile contrast agent is added, guiding sacculus is able to observe that by X-ray in the course of surgery
Whether 20 expand and how is form.
In order to adapt to the environment of internal blood vessel, the gap between seal wire poling 10 and blood vessel is blocked completely, is avoided inverse
Enter the gap between the outer wall and blood vessel of seal wire poling 10 when penetrating seal wire poling 10 to seal wire, further, such as
Shown in Fig. 3 and Fig. 4, guiding sacculus 20 is annular utricule, and annular utricule is set in the end of seal wire poling 10.Guiding sacculus 20 exists
It injects after fluid media (medium) and is formed annular entry 21, annular entry 21 and seal wire poling by compression swelling, the front end of guiding sacculus 20
10 front port 11 is concordant consequently facilitating reverse seal wire penetrates seal wire poling 10.
Further, after guiding sacculus 20 expands, the front end face formation of guiding sacculus 20 is corresponding with its annular entry 21
Pyramidal structure.As shown in figure 5, the front port 11 of seal wire poling 10 is the taper knot to match with the front end face of guiding sacculus 20
Structure.It, can be smooth to enable guiding function of the reverse seal wire when penetrating seal wire poling 10 by the inclined-plane of pyramidal structure
It is rapidly introduced into seal wire poling 10, further increases procedure efficiency.
In addition, being provided with tag block 12 on the front end outer wall of seal wire poling 10, which has contrasting effects, from
And in the course of surgery, shift position of the head end of seal wire poling 10 in cardiovascular can be observed by X-ray.
It the above is only the preferred embodiment of the present invention, it is noted that those skilled in the art are come
It says, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should be regarded as
Protection scope of the present invention.
