The utility model discloses, improved the propelling movement performance of product in the use, kept good compliance and elasticity again simultaneously, be difficult for buckling, reduced hematal injury at the operation in -process, changeed through lesion zone.
Description
Technical field
This utility model relates to a kind of PTA sacculus dilating catheter, specifically, is a kind of medical apparatus and instruments getting involved blood vessel, by mechanical expansion to reach to improve the bleeding capacity of vascular lesion stenosis area.
Background technology
Percutaneous peripheral blood vessel intracavity forming operation PTA adopts Percutaneous Techniques that sacculus dilating catheter is inserted into peripheral blood vessel stenosis, under the guiding and monitoring of medical imaging device, sacculus is extended, makes peripheral blood vessel narrow positions expand, increase peripheral blood vessel bleeding capacity.Existing PTA sacculus dilating catheter is due to the defect in structure and connected mode, the traverse ability of conduit and propelling movement ability, conduit does not have elasticity, therefore conduit is in the process wearing blood vessel, easily bending, being easily damaged, during the narrow zone caused by heavy arterial pathological changes or calcification, success rate is low, is extremely difficult to initial healing purpose.
Utility model content
The purpose of this utility model is to overcome deficiency in existing product, it is provided that a kind of propelling movement ability PTA sacculus dilating catheter good, unpliant.
In order to achieve the above object, this utility model is achieved through the following technical solutions:
A kind of PTA sacculus dilating catheter of the present utility model, including catheter block, catheter block reinforcement, outer tube, sacculus, elastic reinforcement silk, the inside of catheter block is fixed in one end of described outer tube, the other end of described outer tube is inserted in sacculus, interior pipe it is provided with in the cavity of described outer tube, said inner tube is fixing with catheter block to be connected, the diameter of said inner tube tapers into along catheter block to the direction of sacculus, described elastic reinforcement silk is fixing with the outer wall of interior pipe to be connected, described catheter block reinforcement is connected with catheter block, marking ring it is provided with in said inner tube, the outer wall of described outer tube is provided with length mark ring.
This utility model marking ring is positioned at balloon interior.
Elastic reinforcement silk described in the utility model is metal alloy wires.
The material of elastic reinforcement silk described in the utility model is niti-shaped memorial alloy or Nitinol superelastic alloy or medical stainless steel or cobalt chromium dynamax.
Elastic reinforcement silk described in the utility model should adopt centreless grinding or electrochemical polish to process.
The beneficial effects of the utility model are as follows: this utility model is provided with elastic reinforcement silk, improve product propelling movement performance in use, maintain again good compliance and elasticity simultaneously, not pliable, operation process decreases the injury to blood vessel, is more easy to and passes through lesion region；This utility model is provided with length mark ring, reminds doctor when conduit adjacent lesion position so that doctor slowly slowly inserts conduit to Ink vessel transfusing, it is prevented that lesion locations is damaged.

Detailed description of the invention
Below in conjunction with Figure of description, the technical solution of the utility model is described further:
Such as Fig. 1, Fig. 2, shown in Fig. 3, a kind of PTA sacculus dilating catheter, it is characterized in that, including catheter block 1, catheter block reinforcement 3, outer tube 4, sacculus 2, elastic reinforcement silk 6, the inside of catheter block 1 is fixed in one end of described outer tube 4, the other end of described outer tube 4 is inserted in sacculus 2, interior pipe 5 it is provided with in the cavity of described outer tube 4, said inner tube 5 is fixing with catheter block 1 to be connected, the diameter of said inner tube 5 tapers into along the direction of catheter block 1 to sacculus 2, the diameter of interior pipe 5 tapers into purpose and is so that propelling movement power is more uniform, it is more easy to and passes through lesion region, described elastic reinforcement silk 6 is fixing with the outer wall of interior pipe 5 to be connected, described catheter block reinforcement 3 is connected with catheter block 1, marking ring 7 it is provided with in said inner tube 5, the outer wall of described outer tube 4 is provided with length mark ring 41.It is internal that marking ring 7 is positioned at sacculus 2.Elastic reinforcement silk 6 is metal alloy wires.The material of elastic reinforcement silk 6 is niti-shaped memorial alloy or Nitinol superelastic alloy or medical stainless steel or cobalt chromium dynamax.Elastic reinforcement silk 6 should adopt centreless grinding or electrochemical polish to process.
This utility model is provided with elastic reinforcement silk, improves product propelling movement performance in use, maintains again good compliance and elasticity simultaneously, not pliable, decreases the injury to blood vessel, be more easy to and pass through lesion region in operation process；This utility model is provided with length mark ring, reminds doctor when conduit adjacent lesion position so that doctor slowly slowly inserts conduit to Ink vessel transfusing, it is prevented that lesion locations is damaged.
It should be noted that listed above is only a kind of specific embodiment of the present utility model.Obviously, this utility model is not limited to above example, it is also possible to have many deformation.
In a word, all deformation that those of ordinary skill in the art can directly derive from this utility model disclosure or associate, all it is considered as protection domain of the present utility model.
