Abstract
The utility model relates to a catheter with a guide filament. A support frame is one section of circular tube, and is sheathed on the outside of a narrow mouth semi-enclosed outer layer catheter. The catheter is also sheathed with an enclosed type inner layer catheter. One section of the enclosed type inner layer catheter is enclosed, and provided with one section of guide filament inward. The utility model is convenient for being placed and penetrated into the narrow positions of pathological changes, the enclosed catheter can prevent the guide filament from contacting blood and organism tissue, and the restenosis of vascular lumens can be effectively prevented. The operation is safe.
Description
This utility model relates to medical apparatus and instruments.
In the clinical medicine practice,, adopt support to keep somewhere the Therapeutic Method that tube chamber is supported in art one expansion to the narrow sexually transmitted disease (STD) change of human vas and other tube chambers.At present, this is a kind of evident in efficacy, advanced therapy that the patient suffering is little.But, find that in the junior middle school suitable patient (the lumen of vessels support is kept somewhere art can reach 30%～50%) is arranged, after treatment a period of time, the tube chamber restenosis has taken place through placing rack.Discover: the occurrence cause of vascular tube chamber restenosis is vascular smooth muscle cell curing, creeps institute extremely; The occurrence cause of non-vascular tube chamber restenosis be tumor cell hypertrophy institute extremely.The generation of restenosis not only causes health, spiritual misery to the patient, and the wealth of society has also been wasted in the loss on the material in large quantities, and more serious is to have caused passive situation for further treating.
The purpose of this utility model is to provide a kind of pipe guide that seal wire is housed that prevents vascular tube chamber restenosis.
This utility model is realized in the following way:
This pipe guide is made up of used seal wire (6) in support (1), the semi-enclosed outer conductor of slot (2), closed inner conductor (3), guidewire sections (4) and the clinical practice, wherein: support (1) is one section pipe, be enclosed within outside the semi-enclosed outer conductor of slot (2), also be with a closed inner conductor (3) in this conduit, closed inner conductor (3) one ends sealing, have used seal wire (6) in the clinical practice in it, have identical with backing positions, that length is identical one section guidewire sections (4) on this seal wire.
The utlity model has following advantage:
This device is convenient to discharge and is goed deep into to the narrow position of pathological changes, and the conduit of sealing can prevent seal wire contact blood and bio-tissue, and can prevent vascular tube chamber restenosis effectively, and is easy to use, safe and reliable.
Below in conjunction with accompanying drawing this utility model is further described:
Fig. 1 is this utility model front view
Fig. 2 is the A-A cutaway view of Fig. 1
In Fig. 1: (1) support; (2) the semi-enclosed outer conductor of slot; (3) closed layer conduit; (4) guidewire sections; (5) wall of the lumen of blood vessel; (6) used seal wire in the clinical practice; (7) lumen of vessels.
The supporting conduit system of seal wire:
Closed inner conductor: used clinically various model conduits, sealing one end, the seal wire of adaptive respective diameters is to prevent seal wire contact blood and bio-tissue.
。Internal diameter: 0.5mm-30mm, external diameter: 1mm-30mm, length:
30cm-300cm。
The semi-enclosed outer conductor of narrow end on the basis of used clinically various model conduits, makes the one end narrow, and body fluid can be passed through, and can play the effect that the restriction inner conductor is deviate from again.
Internal diameter: 1mm-30mm, external diameter: 1mm-35mm, length:
30cm-300cm。
Claims (1)
1, a kind of pipe guide that seal wire is housed, form by used seal wire (6) in support (1), the semi-enclosed outer conductor of slot (2), closed inner conductor (3), guidewire sections (4) and the clinical practice, it is characterized in that: support (1) is one section pipe, be enclosed within outside the semi-enclosed outer conductor of slot (2), also be with a closed inner conductor (3) in this conduit, closed inner conductor (3) one ends sealing, have used seal wire (6) in the clinical practice in it, this seal wire has identical with backing positions, one section guidewire sections (4) that length is identical.
