Problems solved by technology

Its working principle is to manually squeeze the pump to work, but the disadvantages of this method are: 1. Manual operation is prone to large errors; 2. The control pump is implanted in the scrotum or labia, which will affect the life of the patient
However, the disadvantages of this technology are: 1. The actuator is triangular in shape, and the sharp corners are easy to cause damage to tissues and organs in the body; 2. The energy supply method is not mentioned, and the technical structure is incomplete

Abstract

The invention provides a puborectalis-simulated type dual-ring artificial anal sphincter prosthesis which comprises an upper fixing ring, a lower fixing ring, a connecting support, a power unit, a speed reduction gear box and a movable semi-ring, wherein the upper fixing ring and the lower fixing ring are arranged in parallel, implanted into the periphery of the intestinal tract of a patient to be fixed and arranged at the two ends of the connecting support respectively, the middle of the connecting support is connected with the movable semi-ring, the power unit and the speed reduction gear box are both integrated with the connecting support, and the power unit controls the movable semi-ring through the speed reduction gear box, so that the movable semi-ring moves towards a center hole of the upper fixing ring and a center hole of the lower fixing ring or in the circumferential direction of the upper fixing ring and the lower fixing ring. The puborectalis-simulated type dual-ring artificial anal sphincter prosthesis is small in size, light in weight and capable of increasing the success rate of prosthesis implantation.

Description

technical field [0001] The invention relates to a device in the technical field of artificial prosthesis, in particular to a puborectalis imitation double-ring artificial anal sphincter prosthesis. 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%. 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 tr...
