Magnetostriction type artificial anus sphincter system

Abstract

The invention relates to a magnetically controlled artificial anal sphincter system in the technical field of biomedical engineering. Wherein: the first magnet and the second magnet are connected as a whole through the first coupling rod, the first nut is installed between the first magnet and the second magnet, moves between the first magnet and the second magnet, and pushes the first magnet and the second magnet to control the conduction and disconnection of the first medical catheter and the second medical catheter. The third magnet and the fourth magnet are connected as a whole through the second coupling rod, and the second nut is installed between the third magnet and the fourth magnet, moves between the third magnet and the fourth magnet, and pushes the third magnet and the fourth magnet. The four magnets control the conduction and disconnection of the third medical catheter and the fourth medical catheter. The invention realizes active control of two-way liquid discharge between the clamping bladder and the liquid storage bladder, and realizes the pressure maintaining function in any working cycle.

Description

technical field [0001] The invention relates to a device in the technical field of medical devices, in particular to a magnetically controlled artificial anal sphincter system. Background technique [0002] Fecal incontinence is a clinically common disease. According to statistics, the incidence rate of adults is as high as 2%, and the incidence rate of people over 65 years old can reach 7%. And underestimated. Fecal incontinence refers to the loss of the anal sphincter's ability to control the excretion of feces and gas. It is easy to cause a variety of complications, which not only brings great pain to patients, but also brings many difficulties to nursing work. With the aging trend of the population With the development, fecal incontinence has become one of the clinical diseases that urgently need to be solved. [0003] Severe fecal incontinence is caused by the loss of function of the anal sphincter or the removal of the anal sphincter. The surgical treatment of this f...

AI Technical Summary

Problems solved by technology

There are two disadvantages in the structure of this artificial anal sphincter: 1. The patient must manually squeeze the liquid in the clamp pouch to the pressure regulating ball, which is inconvenient for the patient to use; 2. The pressure regulating ball releases the liquid through its own elasticity. It is discharged into the clamp pouch, and its liquid discharge cannot be controlled, so that the pressure of the clamped colon cannot be controlled, which affects the clamping performance of the clamp pouch
