A kind of magnetic control urethra valveTechnical field
The invention belongs to medical instruments fields, and in particular to a kind of magnetic control urethra valve.
Background technique
Nervous centralis or peripheral nerve be damaged caused by bladder urination dysfunction be a kind of special nature disease,Referred to as neurogenic bladder.Since urogenital system relies on storage and the excretion function of maincenter and peripheral neverous system coordination bladderCan, therefore the urogenital system dysfunction after spinal cord injury produces serious influence to the quality of life of patient, is often accompanied byThe complication such as renal failure, the urinary incontinence, calculus, the retention of urine.
Existing neurogenic mechanisms therapeutic scheme specifically includes that intermittent urethral catheterization, drug therapy, nerve modulation, uropoiesisRoad reconstruction operations, bioengineering treatment, it is therefore intended that urinary tract protection in prevents complication, promotion bladder drainage and supports the familyQuality.However above-mentioned therapeutic scheme universality is poor, complication is serious, success rate is low, clinical therapeutic efficacy is undesirable, therefore developsAuxiliary nervous source property urine incontinence has important clinical practice meaning from the device that master control is urinated.
Summary of the invention
The present invention in order to overcome at least one of the drawbacks of the prior art described above, provides a kind of magnetic control urethra valve, using interiorThe storage urination of formula structure control bladder is set, urethral injury is avoided, while urinating using external magnetic control, to urethral tissue without heat wasteWound.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: a kind of magnetic control urethra valve, wherein includeValve component and the magnet assembly cooperated with valve component；Valve component includes to be placed in the valve body of urethra and cooperate with valve bodySpool, spool can be equipped with the urethral catheterization portion for urination relative to valve body slides, spool, and urethral catheterization portion realizes urine discharge；SpoolElastic component is equipped between valve body, elastic component realizes reset of the spool relative to valve body；Spool includes to cooperate with magnet assemblyTractive unit, tractive unit draws spool relative to valve body slides under the action of magnet assembly.
In the present invention, valve body is placed in urethra, and spool can realize valve body relative to valve body slides, spool and valve body cooperationOpening and closing control urine storage and urination.Spool is equipped with the urethral catheterization portion for urination, and urethral catheterization portion realizes urine after spool openingThe discharge of liquid.Elastic component is squeezed the reset response generated to spool by spool after spool is opened relative to valve body, realizes valveThe reset of core.Spool includes the tractive unit with magnet assembly cooperation, when needing to urinate, is risen by magnet assembly to tractive unitTo sucking action, tractive unit band movable valve plug acts, realizes that spool is opened, carry out urination process.
