Abstract
The utility model relates to a balloon catheter for abutting joint multi-section outer tubes with different diameters, particularly relates to a balloon dilating catheter used for a percutaneous puncture coronary angioplasty of an interventional treatment technology. The balloon catheter for abutting joint of the multi-segments different diameter outer tubes is characterized in that an outer tube (1) and an outer tube (2) which are connected with a balloon (5) are welded together by two or more sections of different diameter outer tubes. The outer tube (2) which is connected with the near end of the balloon is small in diameter, therefore the flexibility is better and complex lesions are easy to pass through. The larger diameter outer tube (1) used in connection with a hypo tube is in favor of strengthening the push force. Through using the two or more sections abut jointed outer tubes, the problems that the push force and the flexibility of a traditional uniform outer tube can not be obtained simultaneously are solved, and the cost is much lower compared to using cone outer tubes.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of sacculus dilating catheter of percutaneous transluminal coronary angioplasty of interventional therapeutic technique.
Technical background
Along with the development of technology, to get involved medical operating and become more and more general, interventional therapeutic technique has the advantages such as wound is little, safety, success rate is high, recovery is fast.In the cardio-vascular interventional therapeutic operation, support is sent into the stenosis of blood vessel by conduit, sacculus, then dilating sacculus struts the support that is fitted on the sacculus, and support is set in blood vessel, makes the blood vessel that has narrowed down recover normal size, guarantees the unimpeded of blood flow.In operation, playing the part of very important role as the foley's tube of induction system, the operation success or failure that the performance at each position of conduit determines.
The even outer tube of the most employings of the foley's tube of producing at present also has the outer tube that uses a taper.Evenly outer tube has the characteristics of easy processing, but its compliance and also need further improve by narrow and small blood vessel; Although having advantages of, the more even outer tube of taper outer tube is easy to by complicated blood vessel and pathological changes, because its process equipment and complex process cause cost to be higher than even outer tube far away.Therefore, be necessary to invent a kind of compliance, trafficability characteristic, propelling movement performance good, and the not high novel outer tube structure of cost.
The utility model content
This utility model purpose: link together to replace a traditional outer tube with two sections or multistage different-diameter outer tube.By using the outer tube of two sections or multistage different-diameter, both promoted compliance and the trafficability characteristic of foley's tube, also strengthened the propelling movement power of conduit, improved operation efficient, reduce operation risk.
The utility model proposes a kind of foley's tube of multistage different-diameter outer tube docking, comprise sacculus, outer tube, hypotube, stress support steel wire, inner tube, developing ring, sacculus and outer tube pad and hypotube and outer tube pad.Outer tube is comprised of the outer tube of the different-diameter of two sections or multistage, and the end that external diameter is less is connected with balloon proximal, and the end that external diameter is larger is connected with hypotube, guaranteed conduit from front to back integral body be cone structure.The outer tube docking can be the various ways such as enlarging and non-enlarging.If use the outer tube flaring, the angle of outer tube enlarging A is between 5 degree～45 degree, and the length of enlarging is between 0.5mm～4mm, and the length B that an other outer tube inserts enlarging is 0.5mm～4mm, and weld length is between 0.5mm～6mm after the docking.Used outer tube can be material of the same race or not of the same race, and its material can be Pebax, nylon, polyurethane, polyethylene or politef.The overall length of outer tube is at 10cm～50cm.Outer tube diameter 0.5mm～1.5mm, single wall is thick to be 0.05mm～0.50mm.
The utility model has the advantage of:
1) outer tube of two or more different-diameters just can link together by methods such as welding through enlarging or directly docking, and technique is simple.
2) the outer tube external diameter that is connected with balloon proximal is less, and then promotes the ability by stenotic lesion.
3) the far-end outer tube external diameter that is connected with hypotube is larger, and rigidity is run well than leading portion is outer, cooperates the stress support steel wire on the hypotube, can guarantee that conduit has better propelling movement, improves the efficient of operation.
4) outer tube that diameter is less is connected with sacculus, has strengthened the compliance of leading portion, is conducive to by complicated blood vessel and lesion region.The outer tube that connection diameter is larger has strengthened the propelling movement performance of conduit, has remedied the less outer tube of leading portion diameter and has pushed hypodynamic defective.
Description of drawings
Fig. 1 is the foley's tube schematic diagram of the far-end body of rod of use outer tube docking;
Fig. 2 is the outer tube schematic diagram of enlarging;
Fig. 3 is the outer tube schematic diagram to connecting.
The specific embodiment
The body cone of choice for use 0.35mm～1mm diameter carries out the enlarging angle between 5 degree～45 degree to the larger outer tube of internal diameter, the length of enlarging is between 0.5mm～4mm, more a little bit smaller outer tube of the outer tube that has expanded mouthful and the diameter of not enlarging docks, connect by connected modes such as laser weld, the length of connection is between 0.5mm～6mm.What the outer tube diameter that connects was little is connected with sacculus, and what diameter was large is connected with hypotube.
