Abstract
The utility model relates to a guide wire for catheter, including hollow stiff guide wire with the flexible guidewire in stiff guide wire walks, flexible guidewire is suitable for and penetrates the urethra, stiff guide wire is suitable for and directly penetrates the urethra or penetrate the urethra along flexible guidewire, and arranges the support piece and the guiding piece of conduct catheter in the urethra in. The utility model discloses a lower urinary tract obstruction section that guide wire for catheter can lead to through diseases such as prostatoplasia, urethral stricture, can flexible guidewire and stiff guide wire jointly use and guide more easily than the exclusive use that the catheter is smooth to advance the bladder.
Description
Technical field
This utility model relates to a kind of medical guiding wire, belongs to technical field of medical instruments.
Background technology
Catheter is clinical practice important medical invasive material widely, is mainly used in per urethra and inserts bladder drainage urine.Because male urethra thickness is different, degree of crook varies, although various types of catheter emerges in an endless stream on market, but be not still applicable to the catheter that different crowd urethral catheterization needs, the Posterior urethral blocked when slightly thin catheter hardness not easily passs through prostatic hyperplasia not, thus bladder can not be entered smoothly; The catheter of slightly thick bore is not then by coarctation segment during urethral stricture.Different narrow section length and different degree of congestion cause needing to use different catheters and seal wire.What is more important, disease usually causes urethral catheterization operating difficulties even to cause urethral catheterization operation failure, especially acute urinary retention state, when being badly in need of drainage of urine, owing to not having suitable urethral catheterization apparatus, can cause serious consequence.
Chinese patent literature CN201431692(application number: 200920027500.9) disclose a kind of guide wire catheter, it comprises seal wire and catheter, in catheter, be provided with seal wire.During use, first seal wire is inserted as support in catheter, after catheter inserts bladder, then seal wire is extracted out from catheter.Seal wire and catheter damage patient body to a certain extent with the use of preventing catheter, but common seal wire still cannot meet the different needs being suitable for crowd and above-mentioned disease treatment.
Summary of the invention
The technical problems to be solved in the utility model is, propose a kind ofly to block state and urethra thickness situation according to different, two kinds of guiding thread for urethral catheters being used alone or in combination, this guiding thread for urethral catheter can coordinate catheter by urethral stricture place, guides catheter to slide into bladder smoothly.
This utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of guiding thread for urethral catheter, the stiff guide wire comprising hollow and the soft seal wire navigated within described stiff guide wire, and described soft seal wire is suitable for penetrating urethra; Described stiff guide wire is suitable for penetrating urethra along described soft seal wire, and is placed in urethra as the support member of catheter and guiding piece.
The one of technique scheme is preferably: the rigidity of above-mentioned soft seal wire is less than the rigidity of stiff guide wire.
When penetrating urethra to make stiff guide wire, resistance is less, a kind of technique scheme preferably: the outer surface of above-mentioned stiff guide wire is provided with hydrophilic coating.
Less to the damage of urethra and surrounding tissue when penetrating urethra to make stiff guide wire, another kind of technique scheme preferably: above-mentioned stiff guide wire is coated with resin bed.
In order to make seal wire and catheter more can be smoothly through urethra, the one of technique scheme is preferably: the front end of above-mentioned stiff guide wire is bending.Thus make seal wire meet the flexibility of male urethra.
In order to reduce the damage even avoided urethra, the one of technique scheme is preferably: the front end of above-mentioned stiff guide wire is blunt nosed.
The degree of depth that seal wire enters is controlled better, being preferably of a kind of technique scheme: above-mentioned soft seal wire and stiff guide wire are equipped with scale mark during in order to operate.
In order to more convenient to operate, the one of technique scheme is preferably: above-mentioned stiff guide wire is shorter than soft seal wire.
This utility model has positive effect:
(1) guiding thread for urethral catheter of the present utility model is made up of two seal wires that soft durometer is different, and the inside of stiff guide wire is provided with the passage passed for soft seal wire.Also can pass through smoothly even if soft seal wire small, flexible urethra is very narrow.Stiff guide wire more greatly can provide metastable support through urethra due to rigidity along soft seal wire, and catheter is guided to Posterior urethral smoothly, and catheter leans on the thrust conduction of self to cross last narrow section and slides into bladder subsequently.Two kinds of seal wires can be used alone also can conbined usage.
(2) guiding thread for urethral catheter of the present utility model coordinates catheter to use together, can avoid causing patient's urethral canal inner wall to damage and bores a hole in ground, prevent the injury caused patient body.
(3) seal wire of the present utility model can meet the needs that different crowd carries out urethral catheterization, is particularly suitable for the emergencies such as the urethral catheterization such as prostatic hyperplasia or urethral stricture hard case or acute urinary retention.
