Abstract

The invention relates to a magnetic-ring artificial sphincter, namely an annular structural device based on magnetic bodies. The magnetic-ring artificial sphincter is formed by connecting a plurality of magnetic bodies in series through connection materials. Expansion and shrinkage with reversibility can be achieved through the magnetic force absorption effect of the magnetic bodies and sliding and flexible characteristics of the connection materials. The magnetic-ring artificial sphincter is embedded around cavity pipelines in the bodies, can simulate functions of a normal human sphincter, can enhance or rebuild the sphincter functions of organs reducing in or losing sphincter force, controls normal flow direction of contents of hollow organs, and can substitute or rebuild sphincter tissues at positions of esophagus, cardia, pylorus, ileocecus, anal canals, bladders, positions around urethral canals, alimentary canals and urinary tract stomas and the like. The magnetic-ring artificial sphincter is convenient in operation, few in manufacture process, reliable in function and wide in application prospect in the field of biomedicine.

Description

一种磁环人工括约肌及其制造和应用方法技术领域[0001] 本发明涉及一种医疗器械,特别涉及一种磁环人工括约肌,即一种基于磁性体的环状结构装置。 One kind of an artificial sphincter, and the manufacturing and magnetic applications TECHNICAL FIELD [0001] The present invention relates to a medical instrument, particularly to an artificial sphincter ring, that is, a cyclic structure of the apparatus based on the magnetic body. 由磁性金属、生物相容性材料及支撑材料构成的磁性体,通过连接材料串联在一起,埋置于体内空腔脏器环周,可代替或重建食道、贲门、幽门、回盲部、肛管、尿道、 肠道及泌尿系造口处等的括约肌结构,增强或重建括约肌力量减弱或丧失的器官的括约能力,控制消化道及泌尿道内容物的正常流向及排泄。 A magnetic metal, the magnetic material and a biocompatible support material in series by connecting together the material, embedded in the circumference of hollow organs in vivo, can replace or rebuild the esophagus, cardia, pylorus, ileocecal, anal tubes, urethral sphincter structures, intestinal and urinary tract stoma or the like, to enhance strength or sphincter reconstruction weakening or loss of ability to sphincter organ, and excretion controlling the flow of normal gastrointestinal tract and urinary tract contents. 背景技术[0002] 括约肌是分布于人体内某些空腔脏器环周的环形肌肉,对于控制空腔脏器内容物的正常流向具有至关重要的作用。 [0002] sphincter is distributed in some hollow organs of the human body circumferential annular muscle, for controlling the flow of the normal content of the hollow organ has a crucial role. 各种原因导致的功能减弱或丧失会引起临床上严重的不良后果,如食管下贲门括约肌功能减弱引起反流性食道炎及Brrett食管,幽门括约肌松弛致胆汁反流性胃炎,尿道括约肌损伤引起尿失禁,肛门括约肌损伤引起大便失禁。 All causes of weakened or loss can cause serious adverse clinical consequences, such as the lower esophageal sphincter weakened cause reflux esophagitis and Brrett esophageal, pyloric sphincter relaxation induced by bile reflux gastritis, urethral sphincter damage caused by the urine incontinence, anal sphincter damage caused by fecal incontinence. 如何对空腔脏器括约肌功能进行恢复和重建已成为临床医生面临的严峻挑战。 How to carry out rehabilitation and reconstruction of hollow organs sphincter function has become a serious challenge facing clinicians. [0003] 以大便失禁为例。 [0003] with fecal incontinence, for example. 美国的一项大规模调查显示普通人群中高达7.1%的人有不同程度的大便失禁。 A large-scale survey showed US general population up to 7.1% of people have varying degrees of fecal incontinence. 大便失禁虽然不能致命,但却给患者带来巨大的生活不便和身心痛苦,甚至造成人格变化。 Fecal incontinence, although not fatal, but it has brought great inconvenience to patients and physical and mental suffering, and even cause personality changes. 为了恢复肛门正常功能,有效控制大便失禁,多年来国内外学者作了多方面的探索,特别是试图通过肌肉移植来重建肛门括约肌功能。 In order to restore the normal function of the anus, effective control of fecal incontinence, over the years made many domestic and foreign scholars to explore, especially in trying to reconstruct the anal sphincter muscle function through transplantation. 虽然在此基础上不断改进手术方式,但肛门功能的恢复并不理想。 While on the basis of the continuous improvement of surgical procedures, but the recovery is not ideal anal function. 1989年Christiansen首先应用人工肛门括约肌控制大便失禁,为大便失禁的治疗开辟了一条新的途径。 1989 Christiansen first application of artificial anal sphincter fecal incontinence control, has opened up a new way for the treatment of fecal incontinence. 近年来,随着生物材料的发展以及对排便生理的认识加深,人工肛门括约肌有了较新的发展,如水泵式人工肛门括约肌与形状记忆合金人工肛门括约肌等。 In recent years, with the development of biological materials and to deepen understanding of the physiology of defecation, artificial anal sphincter with newer developments, such as pumps and artificial anal sphincter SMA artificial anal sphincter. [0004] 水泵式人工肛门括约肌是通过以水泵为动力的套囊在肛管直肠周围制造一个稳定的高压区域来获得控制排便的能力,也称为套囊式人工肛门括约肌。 [0004] The pump is manufactured artificial anal sphincter pump powered by the cuff around a stable high pressure anorectal area to obtain the ability to control defecation, also referred to as cuff artificial anal sphincter. 水泵式人工肛门括约肌的设计过于复杂,套囊和贮液囊容易腐蚀导致机械故障,因此不能长久应用。 Artificial anal sphincter pump design is too complex, the cuff and the reservoir bag easily lead to corrosion of mechanical failure, it is not long application. 而且套囊在体内没有固定,在周围的脂肪组织中仍有一定的活动空间,因此,套囊由于反复活动对周围组织特别是肛周浅表组织经常性的刺激势必产生炎性反应;加之套囊不均勻的高压作用,导致组织的腐蚀、感染、疼痛、伤口裂开等一系列并发症,从而限制了其在临床的广泛应用。 And not fixed to the cuff body, the adipose tissue surrounding still some space, therefore, the cuff surrounding tissues due to repeated activities particularly perianal recurrent superficial tissue inflammatory response stimulation bound; cuff is not coupled with a uniform high pressure, cause corrosion, infection, pain, wound dehiscence series of complications tissue, thereby limiting its widespread clinical application. [0005] 形状记忆合金人工肛门括约肌主要是由两条双程形状记忆的钛-镍合金为主要材料,两端分别用铰链连接起来形成的一个椭圆环。 [0005] Shape memory alloy is mainly composed of an artificial anal sphincter titanium way shape memory of two pairs - a nickel alloy as the main material oval ends were hinged together to form a ring. 经过两次特殊处理之后,在体温时呈扁平的形状,而加热到52°C就变成弧状。 After two special treatment, has a flat shape at body temperature, heated to 52 ° C becomes an arc. 记忆合金在这两个温度间可以发生形状变化,在体温状态下扁平形状的记忆合金夹闭肠腔,加热之后记忆金属就变成椭圆形开放肠腔。 The shape memory alloy can vary between these two temperatures, a flat shape at body lumen occlusion state memory alloy, after heating the memory metal becomes elliptical open lumen. 但是,形状记忆合金人工肛门括约肌压迫肠组织部分会形成纤维包膜,而这个纤维包膜会引起闭合压力的改变从而导致顺应性下降及开闭失灵。 However, the shape memory alloy artificial anal sphincter intestinal tissue compression branch portion formed fibrous capsule, and this will cause the fibrous capsule closure pressure change resulting in decreased compliance and thereby open and close failure. 另一方面,局部组织加热至52°C左右在很多病人是无法承受的。 On the other hand, localized tissue heating to about 52 ° C in many patients can not afford. 发明内容[0006] 本发明的目的在于:克服现有的人工括约肌的缺点,提供一种极为简便、制造工序少、材料简单、能耗小、投入资金少、适合实验室研究制备和医疗器械行业大规模生产的人工磁环括约肌。 SUMMARY [0006] The present invention is: to overcome the disadvantages of the prior artificial sphincter, to provide an extremely simple and less manufacturing process, simple materials, low energy consumption, less investment, preparation for laboratory research and medical device industry mass-produced artificial sphincter ring.
