Abstract
The utility model relates to an improved peripheral vascular balloon dilatation catheter which comprises a distant end and a near end of a catheter head; the distant end and the near end of the catheter are connected with a balloon and an inner catheter. Two developing material marks are installed under the boundary of two sides of the balloon on the outer surface of the distant end of the inner catheter; the near end of the balloon is connected with an outer catheter A; the outer catheter A is connected with an outer catheter B; the inner catheter penetrates hollow cavities of the outer catheter A and the outer catheter B to form a double-cavity structure; the inner catheter is led out at the rear end of the outer catheter B and is connected with a handle outlet; and the tail end of the outer catheter B is connected with the handle outlet. As the diameter of the outer catheter A is gradually reduced from the balloon to the outer catheter B, the improved peripheral vascular balloon dilatation catheter can effectively reduced the passing diameter of the catheter, simultaneously ensures that a guiding wire can penetrate the whole cavity of the peripheral vascular balloon dilatation catheter and the physician can better apply force to the peripheral vascular balloon dilatation catheter, and the penetration capability and the push capability of the catheter are enhanced.
Description
Technical field
This utility model relates to a kind of modified model peripheral blood vessel sacculus dilating catheter, particularly a kind of sacculus dilating catheter that is used for the percutaneous peripheral blood vessel intracavity forming operation (PTCA) of interventional therapeutic technique.
Background technology
Interventional technique grew up in the later stage seventies, it is under medical imaging (X ray, ultrasonic, CT, MRI etc.) guiding, by the percutaneous puncture approach or by the original duct of human body, interposing catheter or apparatus are delivered to diseased region diagnose radiography, treatment or tissue sampling.Percutaneous peripheral blood vessel intracavity forming operation is to adopt the percutaneous puncture technology that sacculus dilating catheter is inserted into the peripheral blood vessel stenosis, under the guiding and monitoring of medical imaging device, sacculus is expanded, made the expansion of peripheral blood vessel narrow positions, increase the peripheral blood vessel blood flow.Existing modified model peripheral blood vessel sacculus dilating catheter is because the defective on structure and the connected mode, the ability of passing of conduit and push ability, and success rate is low during by serious arterial disease or narrow zone that calcification caused.
Summary of the invention
The purpose of this utility model is to change the defective on existing peripheral blood vessel sacculus dilating catheter structure and the connected mode, provide a kind of ability of passing and propelling movement ability stronger modified model peripheral blood vessel sacculus dilating catheter, thus the success rate when improving the peripheral blood vessel sacculus dilating catheter by serious arterial disease or narrow zone that calcification caused.
The purpose of this utility model is achieved in that a kind of modified model peripheral blood vessel sacculus dilating catheter, comprise the tube head far-end, the tube head near-end is connected with interior pipe with sacculus, interior pipe distal outer surface, two developing material labellings are installed under the border, sacculus both sides, balloon proximal is connected with outer tube, outer tube A is connected with outer tube B, interior pipe runs through outer tube A and outer tube B cavity, form double cavity structure, interior pipe passes at outer tube B near-end, is connected with the handle outlet, outer tube B end links to each other with the handle outlet, and it is characterized in that: outer tube A diameter is held from the sacculus end to outer tube B and reduced gradually.
Described tube head refers to pusher foremost, and its near-end is that laser weld is connected with the connected mode of sacculus and interior pipe.
Pipe distal outer surface in described is installed two developing material labellings under the border, sacculus both sides, be used to indicate the sacculus effective length, and connected mode is that laser weld connects or viscose glue curing connects.
The diameter of described balloon proximal pipe is bigger than outer tube A diameter, and the balloon proximal pipe box is on outer tube A during welding, and intersection is 0.5-3mm, and connected mode is that laser weld connects.
Pipe passes at outer tube B near-end in described, solidifies by viscose glue with the handle outlet to be connected, as the service aisle of seal wire.
The terminal curing by viscose glue with the handle outlet of described outer tube B is connected, as the transfer passage of balloon expandable or contrast agent.
Described outer tube A diameter is bigger than outer tube B diameter, and outer tube A is enclosed within on the outer tube B during welding, and intersection is 0.5-3mm, and connected mode is that laser weld connects.
The maximum that this utility model is removed handle portion is no more than 0.35mm by diameter (the folding back of sacculus), and effective length is 800-1400mm.
This utility model since outer tube A diameter hold from the sacculus end to outer tube B and reduce gradually, therefore can effectively reduce the diameter that passes through of conduit, make guiding wire can run through whole peripheral blood vessel sacculus dilating catheter inner chamber simultaneously, make operative doctor can better power be applied to the peripheral blood vessel sacculus dilating catheter, the ability of passing and the propelling movement ability of conduit have been strengthened, the parts assembling mode has also reduced the integral body of conduit greatly by diameter, has strengthened the ability of passing of conduit.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a sacculus dilating catheter structural representation of the present utility model.
Fig. 2 is an outer tube A partial enlarged drawing of the present utility model.
The specific embodiment
