Description
Technical field
The utility model embodiment is related to technical field of medical equipment, and in particular to a kind of magnetic-type two-way to join forces radiography and lead
Pipe.
Background technique
With the made rapid progress of medical instrument, intervenes surgical procedure and be applied to more and more disease areas, blood vessel intervention
Operation constantly broken through towards the direction to become increasingly complex, difficulty is increasing, precision medical treatment, Personalized medicine theory it is emerging
It rises and requirements at the higher level also is proposed to the precision of intervention material, individuation, safety.The intracavitary overlay film frame hand of aortic disease
The successful implementation of art is often limited to the complication of the mistake lid of important branch.To solve this problem, high-caliber operative doctor is opened
The technology that " external windowing ", " windowing in vivo " are carried out to the overlay film part of aortic stents is come up with invasively.Although obtaining
Some successes, but respectively have its drawback: the essence of " windowing " and aortic branch opening after the bracket merging in vivo of 1. " external windowings "
Quasi- pairing is difficult to ensure；2. existing " windowing in vivo " mode is that the sharp weapon (stiff guide wire) of " windowing " are completely exposed to blood to follow
The dangerous way of ring, laser burn bracket overlay film inevitably result in circulation haemocyte heat damage, and downright bad product enters blood of human body
Circulation causes fever, foreign matter embolism etc. to endanger.Either punctured in vivo using stiff guide wire hardhead or long puncture needle, it is hard
Hard sharp weapon may all accidentally injure aorta and cause arteriorrhexis bleeding, in addition, hard sharp weapon make operator can not autonomous control wear
Direction is pierced, exit foramen primum accidentally there is also sharp weapon after one hole of puncture and needs the case where puncturing again.
Utility model content
For this purpose, the utility model embodiment provide it is a kind of it is magnetic-type it is two-way join forces angiography catheter, to solve in the prior art
The sharp weapon to open a window when due to opening a window in vivo are fully exposed to that downright bad product can be generated when opening a window caused by sanguimotor place
Into the problem in human body.
To achieve the goals above, the embodiments of the present invention provides the following technical solutions:
In the first aspect of the embodiments of the present invention, provide it is a kind of it is magnetic-type it is two-way join forces angiography catheter,
Including the first angiography catheter and the second angiography catheter；First angiography catheter is embedded with the pole S annular magnetic by the position of close end
Piece；Second angiography catheter is embedded with and the matched N polar ring shape magnetic sheet of the S polar ring shape magnetic sheet by the position of close end.
Further, first angiography catheter can bend arc-shaped structure close to one end of the S polar ring shape magnetic sheet.
Further, second angiography catheter can be bent into and described close to one end of the N polar ring shape magnetic sheet
The matched arcuate structure of one angiography catheter.
Further, the inside and outside wall that first angiography catheter is located at S polar ring shape magnetic sheet position is coated respectively with PVC painting
Layer, the inside and outside wall that second angiography catheter is located at N polar ring shape magnetic sheet position are coated respectively with PVC coating.
Further, the outer diameter of first angiography catheter and second angiography catheter is that 2.33mm, internal diameter are
1.33mm, the PVC coating are 0.1mm.
Embodiment according to the present utility model, it is a kind of it is magnetic-type it is two-way join forces angiography catheter have the advantages that into
When the internal fenestration operation of row, more accurate window point is capable of providing by angiography catheter and is selected；By the first angiography catheter and
Second angiography catheter is by the effect that N polar ring shape magnetic sheet and S polar ring shape magnetic sheet attract each other in vivo through two-way importing human body
First angiography catheter and the fitting of the second angiography catheter, make the first angiography catheter and the second angiography catheter be respectively at blood vessel membranous wall
Two sides；To which when carrying out fenestration operation, risky operation face is limited in the intracavitary portion of angiography catheter, effectively reduces and avoid and is " hot broken
Bad haemocyte enter circulation cause fever, foreign matter embolism, aorta accidentally injure ", instrument surprisingly deviate from and need repeat " windowing "
The harm such as risk of operation, the difficulty for greatly reducing " windowing in vivo " make " windowing in vivo " technology more safety and are easier to
It promotes.
