The controlled curved balloon catheter device of this no seal wire comprises combined catheter 1, branch type connector 4, outer sacculus 6 and interior sacculus 9, it is characterized in that: described outer sacculus 6 and interior sacculus 9 concentrics are arranged between the conduit middle-end 5 and distal end of catheter 8 of combined catheter 1; And, described outer sacculus 6 is connected with outer sacculus pressurising interface 2 on being located at branch type connector 4 through combined catheter 1, sacculus 9 is connected with interior sacculus pressurising interface 3 on being located at branch type connector 4 through combined catheter 1 in described, thus the controlled curved balloon catheter device of the no seal wire of formation.
Sacculus 9 employing diameters are the sacculus of 1 ?3mm in described, and described outer sacculus 6 adopts diameters 2 ?15mm.
The two ends of sacculus 9 are provided with the point 7 that develops in described.
The using method of the controlled curved balloon catheter device of this no seal wire is: be divided in blood vessel, enter diseased region and outside sacculus pressurising blood vessel dilating diseased region two processes.
In A, the process that in carrying out blood vessel, advances, when running into crooked blood vessel, use the slow pressurising of the inside sacculus of developer solution, and observe the position of sacculus part in the combined catheter by equipment such as X-rays; Increase gradually along with the endosphere intracapsular pressure, interior sacculus can be crooked gradually, when interior balloon shaft to bending radius and the flexibility radius that need to advance blood vessel roughly quite the time, by the direction of operator at external rotation combined catheter afterbody adjustment combined catheter front end position, make the sacculus position of combined catheter pass the vascular bending position behind the select location; Subsequently internally sacculus pressure release to 1 ?2 atmospheric pressure so that continue to use by the vascular bending position next time.
B, after foley's tube reaches diseased region, after the development point at sacculus two ends determines that the effective site of sacculus covers diseased region fully in utilizing, with the complete pressure release of interior sacculus, then with outer sacculus pressurising expansion, till the diameter at vascular lesion position reaches requirements of operation.
In operation process, at first allow this foley's tube enter the blood vessel of diseased region along the sheath pipe, boost by interior sacculus pressurising interface 3 inflations subsequently, simultaneously by rotating the foley's tube body of sheath pipe outside, sacculus increases synchronously along with the increase of pressure in making, flexibility until sacculus is consistent with the flexibility of blood vessel, makes the front end of conduit smoothly by the vascular bending position, thereby drives whole ball ductus bursae smoothly by the vascular bending position.
This utility model is taked the crooked mode of sacculus part active of conduit in the process that conduit pushes, and makes conduit be fit to the bending of blood vessel naturally, and conduit is passed through along blood vessel under controlled condition, reduces the propelling movement power of conduit.Improve the easy degree that conduit enters diseased region, entered at conduit and directly use pipe guide in the process of diseased region, need not the guiding wire guiding.

This utility model is taked the crooked mode of sacculus part active of conduit in the process that conduit pushes, and makes conduit be fit to the bending of blood vessel naturally, and conduit is passed through along blood vessel under controlled condition, reduces the propelling movement power of conduit.
In the course of the work, concrete steps are as follows:
Sacculus in the technical program partly is divided into: outer sacculus 6 and interior sacculus 9, in whole combined catheter structure, outer sacculus and traditional foley's tube need folding the pressure to hold equally, in operation process, combined catheter 1 enters diseased region along the sheath pipe, when running into vascular bending or distortion, traditional conduit can only be gone over the propelling movement energetically of guiding wire, this utility model then adopts suppresses interior sacculus 9, under the effect of certain pressure, make in sacculus 9 in the blood vessel of bending from line bend.Because it is crooked synchronously that the bending of the interior sacculus after the punching press can drive outer balloon, cause part (sacculus part) meeting of the front end of whole conduit crooked, and crooked direction can be adjusted realization by externally rotating combined catheter, the bending of sacculus increases along with the increase of balloon pressure, crooked consistent up to the bending of sacculus and blood vessel, the far-end that so just can guarantee combined catheter passes through crooked position smoothly, and the whole conduit of meeting drive that pass through of front end passes through crooked position smoothly, reduced the difficulty that conduit passes through crooked position, the conduit of this type will avoid using guide wire in operation process simultaneously.
Owing to adopt the design of two sacculus, therefore on the mode that realizes, it is the sacculus of 1 ?3mm that interior sacculus adopts diameter, and concrete length should determine that outer sacculus adopts diameter 2 ?15mm according to designing requirement.Two sacculus adopt the mode of laser weld to finish connection.Adopt double lumen tube or double pipe structure to connect between sacculus and the pressurising mouth.
Conduit enters the easy degree of diseased region, enters at conduit and directly uses pipe guide in the process of diseased region, need not the guiding wire guiding.
Under the situation of not using guiding wire, control the flexibility of sacculus by the design of two sacculus, foley's tube is easy to by crooked blood vessel or diseased region.
Compare with traditional conduit, the advantage of the controlled curved balloon catheter device of this no seal wire that this technical scheme proposes is:
1, avoided traditional operation to adopt guiding wire to the conduit channeling conduct;
2, become traditional passive initiatively crooked shape that adapts to blood vessel of conduit that is bent into of conduit, alleviated the difficulty that conduit pushes greatly.Under the mode of traditional guiding wire, during vascular bending, conduit often need could be crooked to blood vessel on the top, and especially the radius of curvature of vascular bending is hour, often conduit is subjected to bigger power and could begins crookedly, and this situation often causes the damage of blood vessel easily.And the technical program is when running into vascular bending, and catheter proximal end is along with blood vessel is initiatively crooked, and having avoided energetically, the top causes blood vessel injury to blood vessel.
3, conventional catheters arranges a guidewire lumen, be beneficial to the guiding of guiding wire, and the sacculus in the technical program, because do not re-use the guiding wire guiding, therefore not be used in guidewire lumen is set, in the whole surgery process, human body fluid only contacts the outer surface part of conduit like this, compare with conventional catheters and to have reduced the inner surface that body fluid contacts conduit, reduced the probability of operation process inadvertent contamination.
4, can effectively avoid the generation of the guidewire lumen locking guiding wire phenomenon of the conduit that occurs in the traditional operation, be conducive to the propelling movement of conduit and return and remove.
