Embodiment

[0022] Such as Figure 1-4 As shown, the present embodiment provides a bionic anal sphincter regulating device based on electric pulse regulation, which includes a sphincter regulating body 1 and an excretory part 3. The cross section of the sphincter regulating body 1 is in the shape of a hollow ring. The compatible film layer 2 and the excretory part 3 are placed in the hollow cavity of the sphincter regulating body 1, and the sphincter regulating body 1 is provided with a contraction and expansion cavity 4; the contraction and expansion cavity 4 is provided with a ring-shaped contraction and expansion part 7, and the contraction and expansion part The inside of 7 runs through the wire, and the wire is electrically connected to the electric pulse generator 6 through two electrode interfaces 5. The electric pulse generator 6 is placed between the inner cavity of the sphincter regulating body 1 and the outside of the contraction and expansion chamber 4, and the sphincter regula...

Abstract

The invention provides a bionic anal sphincter regulation and control device based on electric pulse regulation and control, and relates to the technical field of medical devices. The bionic anal sphincter regulation and control device comprises a sphincter regulation and control body and an excretion part, wherein the section of the sphincter regulation and control body is in a hollow circular ring shape, the periphery of the sphincter regulation and control body is wrapped with a compatible film layer, the excretion part is arranged in a hollow cavity of the sphincter regulation and controlbody, a contraction and expansion cavity is formed in the sphincter regulation and control body, an annular contraction and expansion part is arranged in the contraction and expansion cavity, and a wire penetrates through the interior of the contraction and expansion part and is electrically connected with an electric pulse generator through two electric interfaces. According to the regulation andcontrol device, pulse signal current is led into the wire along an electrode interface to stimulate contraction and expansion of the contraction and expansion part, so that excretion of feces is effectively controlled, and leakage of the feces is prevented; and the regulation and control device has few parts, the electric pulse generator and other elements are integrated in the sphincter regulation and control body to form an integrated structure, the installation space is saved, and regulation and control are convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bionic anal sphincter regulating device based on electric pulse regulation. Background technique [0002] Fecal incontinence caused by the failure of human anal function is a common disease. Although it is not fatal, it causes both physical and mental pain to the patient, and also brings a great burden to the patient's family and society. In order to effectively control anal incontinence and restore the normal function of the anus, there are mainly two types of bionic anal sphincter structures that have been developed so far: water pump anal sphincter and shape memory alloy anal sphincter. The main disadvantage of the water pump anal sphincter is that the design is complicated, mechanical failure is prone to occur, and the flow rate of the micropump is small, which leads to an increase in the contraction time of the pincer sac and makes the patient's defecation time too...
