Description
Technical field
The present invention relates to a kind of apparatus of technical field of medical instruments, specifically is a kind of magnetostriction type artificial anus sphincter system.
Background technology
Fecal incontinence is common clinically a kind of disease, and up to 2%, over-65s person sickness rate can reach 7% according to the adult sickness rate of statistics, and the sickness rate Chang Yinzhong person of in fact this disease is ashamed of seeking medical advice and is underestimated.Fecal incontinence is meant that anal sphincter loses the control ability to feces and gas discharge, it causes multiple complications easily, not only bring very big misery to the patient, and bring many difficulties to nursery work, along with the development of aged tendency of population trend, fecal incontinence has become one of disease of urgent clinical needs solution.
Reason causes severe fecal incontinence disease owing to anal sphincter loss of function or anal sphincter be cut etc., and the method for this fecal incontinence of surgical intervention has intestines ostomy and artificial anal sphincter.Intestines ostomy is the last selection scheme of surgical intervention fecal incontinence, and it is a kind of effective means of saving life, but it is physiological deformity of a kind of violation or deformity, makes patient's quality of life and quality of life be subjected to very big influence.Artificial anal sphincter is to use artificial organ-artificial anal sphincter to treat the fecal incontinence disease.Artificial anal sphincter (Artificial Anal SPhincter) is used for surgical intervention fecal incontinence disease clinically abroad, and obtains good effect.
Find through literature search prior art, the United States Patent (USP) Artificial Anal Sphincter (patent No.: US 7,022,622 B2) relate to a kind of artificial anal sphincter that is used for the treatment of fecal incontinence, this artificial anal sphincter comprises pressure and regulates ball, control pump and three parts of clamp capsule bag, this artificial anal sphincter has been applied to clinical, by surgical operation artificial anal sphincter is implanted in patient's body.Pressure regulates ball and clamp capsule bag passes through control pump UNICOM together, the inside full of liquid, the liquid that pressure is regulated in the ball flows into clamp capsule bag by orifice valve under the certain pressure effect, clamp capsule bag surrounds around the colon, has inside expansion extruding colon function, when liquid in the clamp capsule bag increases, extruding colon under pressure inwardly expands, reliable clamp is lived colon, colonic contents is not leaked, when the needs of patients defecation, the patient pushes control pump, liquid in the clamp capsule bag is expelled to pressure regulates ball, clamp capsule bag unclamps the clamping down on of colon, and the patient gets final product normal defecation, after defecation finishes, pressure is regulated ball and by orifice valve liquid is drained back to clamp capsule bag, and clamp capsule bag recovers the clamp to colon, guarantees that colonic contents can not leak.Structurally there are two shortcomings in this artificial anal sphincter: 1, the patient must be expelled to pressure with liquid in the clamp capsule bag by the manual squeezing mode and regulate ball, and the patient uses inconvenience; 2, pressure is regulated ball and by self elastic force liquid is expelled to clamp capsule bag, and its liquid output can not be controlled, and the pressure of clamping down on colon can not be controlled, and influences the clamp performance of clamp capsule bag.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, a kind of magnetostriction type artificial anus sphincter system is proposed, this system is according to sphincter function, can realize the clamping of colon and unclamps the clamping down on of colon by powering up, and can realize that the pressure that clamps colon regulates.
The present invention is achieved through the following technical solutions, the present invention includes: first micromotor, first screw rod, first magnet, first nut, first coupling bar, second magnet, first pull bar, bearing, the first piston plate, first enclosing cover, first medical catheter, the first piston chamber, first shell, second medical catheter, the reservoir bag, the 3rd medical catheter, second enclosing cover, second plunger shaft, second piston plate, second pull bar, second bearing, the 3rd magnet, second coupling bar, second shell, clamp capsule bag, the 4th medical catheter, second micromotor, the 4th magnet, second nut, second screw rod.The annexation of each several part: first micromotor and first screw rod, one end are fixed together, the first screw rod other end is fixed on first shell by clutch shaft bearing, first magnet and second magnet are connected into as a whole by first coupling bar, be installed in first shell.And first nut that first screw rod spins together is installed between first magnet and second magnet, and first nut material is that non-magnet material processes.First pull bar, one end is fixed on first nut, the other end is fixed on the first piston plate, first piston plate, first shell and first enclosing cover constitute an airtight first piston chamber, when first micromotor energising rotation drives the rotation of first screw rod, first nut translation to the left or to the right that spins together with first screw rod, drive the translation to the left or to the right of first piston plate by first pull bar, change the first plug cavity volume of living.First medical catheter, one end and first piston chamber link, and the other end is pressed between first magnet and the first micromotor end face by first magnet, link with clamp capsule bag after passing first shell.Second medical catheter, one end and first piston chamber link, and the other end is installed between second magnet and first shell, link with the reservoir bag after passing first shell.
