Problems solved by technology

[0006] In view of the problems existing in the existing artificial anal sphincter (device), the purpose of the present invention is to provide an artificial anus prepared by using biocompatible material PDMS and Wacker 612 medical silica gel as a structure, IPMC as a driving material, and adopting encapsulation technology. And the sphincter device for realizing the function of opening and closing the anus

Embodiment Construction

[0022] The artificial anus of the present invention includes a support body 1 , an open and close ring 2 , and an IPMC driver 3 .

[0023] see figure 1 , the support body 1 is a ring structure, in order to avoid the defecation resistance caused by the structure, the upper part is thinner, the lower part is thicker, the upper and lower parts are transitioned by the smooth curved surface 1-1 on the inner wall, and the lower ring end is evenly opened along the circumference There are several grooves 1-2, a group of electrodes 1-3 are arranged in the grooves, IPMC driver 3 ( Figure 4 ) is fixed in this groove.

[0024] The support is made of polydimethylsiloxane (PDMS) by thermal curing. As a structure, the hardness of PDMS is an important parameter. If it is too hard, it will feel uncomfortable after being implanted in the human body. If it is too soft, it will not be able to play a supporting role. The mass ratio of the PDMS main agent to the hardener of the present inventio...

Abstract

The invention discloses an artificial anus and a sphincteric device thereof. The artificial anus and the sphincteric device thereof are characterized in that novel intelligent materials are adopted for simulating functional performance of the human body muscle structure, the structural design enables the artificial anus to be similar to a human body anal sphincter from the perspective of bionics, and biological compatible materials such as polydimethylsiloxane (PDMS) and medical silicon rubber are adopted as structure bodies. The artificial anus and the sphincteric device thereof are simple in structure, convenient to manufacture, and capable of achieving the function of the human body anal sphincter through simulation. Moreover, if the artificial anus and the sphincteric device thereof can be popularized, burdens of families and pain of patients can be reduced greatly, and actual application value is high.

Description

technical field [0001] The present invention relates to the application technology of electroactive materials, in particular to an artificial anus prepared by encapsulation technology using biocompatible materials (flexible silica gel) as the structural body, ion polymer-metal composite material (IPMC) as the driving material, and the anus. Bracket device. Background technique [0002] Fecal incontinence caused by the failure of human anal function is a common disease. Although it is not fatal, it will cause both physical and mental pain to the patient, and it will also bring 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, medical personnel have used drugs, anal control plugs and other means to restore the partial function of the anus, but all can not achieve good results. [0003] The artificial anal sphincter structures that have been developed so far mainly include the foll...
