Abstract
The present invention discloses an external dynamic magnetic field driving an artificial sphincter. A miniature pump is driven to work by a magnetic pole on a driving part of the miniature pump in vivo and the magnetic pole is driven by a dynamic magnetic field generated by an external controller. The miniature pump can pump liquid in a sleeve to a ball bag for storing liquid and adjusting pressure. When the ball bag is expanded and pressurized, the sleeve is loosened, and users can defecate. When a controller is removed or power is cut, the liquid in the ball bag for storing liquid and adjusting pressure flows back to the sleeve by a damping gap of a pipe and the miniature pump. When the sleeve is filled and inflated, an anal canal or urethra is locked, and the defecation is stopped. The miniature pump is provided with a liquid supply and fluid replacement puncturation window which is communicated with the inner cavity of the pump. Both ends of the sleeve are provided with hasps and fastened by lock rings. The present invention has convenient use and overcomes the defect of awkwardness. The present invention is suitable for artificial anal canals and urethra sphincters.

The specific embodiment
Please referring to Fig. 1, the artificial anal sphincter that is loaded on 8 li of pelvic cavity is made up of oversleeve 3, micropump 4 and storage liquid adjust blood pressure sacculus 7, be communicated with by conduit 5 between micropump and the oversleeve, be communicated with by another conduit 6 between micropump and storage liquid adjust blood pressure sacculus, oversleeve is enclosed within on the anal canal 2, and micropump plants that to be embedded in stomach wall subcutaneous, and fluid infusion window window will be inclined to skin, storage liquid adjust blood pressure sacculus is arranged in the pelvic cavity, and oversleeve, micropump and oversleeve constitute the system of a closed liquid communication.Controller 1 is located at external, is cylindric (Fig. 2), during work, with micropump permanent magnet (pressing assigned direction) in the close body of permanent magnet in the controller; Can be loaded in the dressing pocket at ordinary times, the housing of controller is installed with the moving field generator for 12 li, with the rotating magnetic field generator is example, the simplest rotating magnetic field generator is the magneto structure, it is by motor 9, permanent magnet 10, magnet radial poles, button 13 and battery 14 are formed, permanent magnet is installed on the main shaft of motor, permanent magnet is provided with magnet radial poles (N, S), motor adopts miniature cocurrent electromotor, when the rotation of motor drives permanent magnet, magnetic pole (N, S) with regard to rotation and formation rotating excitation field, when controller forms certain magnetic moment near the polar magnetic field on micropump rotating excitation field and the micropump driving link, just drive micropump work.Micropump in the present embodiment is selected screw pump (Fig. 3) for use, screw pump by have the polar permanent magnet 15 of warp-wise, initiatively screw rod 16, driven screw rod 17, the pump housing 21 are formed, magnetic pole is located at the initiatively end of screw rod, be provided with puncture window 19, inlet 20 and liquid outlet 22 in the pump housing, when micropump stopped, the pressure fluid in the storage liquid adjust blood pressure sacculus can be back to oversleeve through the damping slit.Oversleeve (Fig. 4, Fig. 5, Fig. 6) is made up of elastic rubber tube 23, limit for length's structure net 24, blind end 25, hasp 26, siphunculus hasp 27, conduit 28 and lock ring 11, and conduit passes the siphunculus hasp and is communicated with the elastic rubber tube inner chamber.During use oversleeve is trapped among on anal canal or the urethra, limit for length's fabric web is positioned at the outside, and two blind ends have folded and have been close to, and put lock ring then in the open slot of two hasps and get final product.Storage liquid adjust blood pressure sacculus is to make with elastic silicone rubber, simple in structure, make easily, pressure and volume are controlled easily, when micropump turns round, pumping liquid injects storage liquid adjust blood pressure sacculus from oversleeve, the volume of this sacculus increases gradually, intrinsic pressure also increase, when micropump quits work, storage liquid adjust blood pressure sacculus can push liquid gradually and be back in the oversleeve, till the isostasy in artificial sphincter system, this pressure is suitable for locking anal canal or urethra, and liquid return speed is relevant with the intrinsic pressure magnitude of pressure differential of storage liquid adjust blood pressure sacculus and oversleeve, be that oversleeve is set in urethra 18 when the relevant external driving artificial sphincter of size that the slit of micropump inner chamber and screw rod forms damping is used to solve urinary incontinence (Fig. 7) also, all the other are identical with Fig. 1.Use when of the present invention, the sealing sphincter system that at first will implant charges into liquid, is injected liquid measure and is adjusted to suitable pressure by the puncture window with syringe at last, makes oversleeve full, and anal canal or urethra are in blocking, stop defecation; When the needs of patients defecation, the motor start-up of controller, and controller is moved on to the magnetic pole position of micropump, under the effect of controller rotating excitation field, micropump is through inlet, conduit is extracted the liquid in the oversleeve out, and liquid is depressed into storage liquid adjust blood pressure sacculus by liquid outlet and another conduit, oversleeve is loosened and is got final product defecation, store the supercharging of liquid adjust blood pressure sacculus simultaneously, just finish, remove controller or powered-down, the pressure fluid in the liquid storing ball capsule is through conduit, the damping slit of micropump is back to oversleeve, oversleeve is filled swell, locking anal canal or urethra, stop defecation the present invention and can be used for artificial anal sphincter or artificial sphincter of urethra, solve the gatism problem, also can be used for penis implant's prosthese.
