Description

植入式人造肛门 Implantable artificial anus

技术领域 FIELD

一种植入式人造肛门,涉及一种机械性的植入人体内使用的人造肛门。 An implantable artificial anus, an artificial anus relates to a mechanical implant used in humans. .背景技术. .Background technique.

从1908.年Miles倡导提出的经腹会阴联合切除直肠癌的术式,近百年来各种改良术式及综合治疗的发展进步使直肠癌患者5年生存率达到60% 左右,早期根治术5年生存率达到80—90%。 From 1908. In Miles advocate proposed abdominal perineal resection of colorectal cancer surgical procedures, surgical procedures over the past century and various improvements and the development and progress of the comprehensive treatment of patients with colorectal cancer 5-year survival rate of around 60%, early radical surgery 5 year survival rate of 80-90%. 随着生存率的提高,生存质量的问题引起医学界的广泛关注。 With the improvement of survival, quality of life issues caused widespread concern in the medical profession. 如何取代切除的肛门,尽可能恢复自然肛门功能是这一难题的焦点。 How to replace the removal of the anus, anal function as much as possible to restore the natural focus of this problem. 现行常规做法是腹壁人造假肛,术后管理不便,且使患者及亲属从心理上难以接受。 Current standard practice is that artificial abdominal wall anus, inconvenience postoperative management, and so that patients and relatives difficult to accept psychologically.

目前关于肛门功能恢复的方法丰要有两种类型。 Current methods on anal function recovery have abundance of two types. 一类是通过手术重建或肌. 肉移植代替肛门括药肌功能,重建肛门括约肌的术式主要有(l)'结肠折叠肛管重建术;(2)重建直肠角、结肠折叠式肛门萬建术,(3)结肠贮袋式肛门重建术。 . One is by surgical reconstruction or transplantation of muscle anal muscle function including drugs, surgical reconstruction of the anal sphincter major (l) 'folded colon anal reconstruction; (2) the reconstruction angle rectum, anus colon folding WAN Jian surgery, (3) colon reservoir bag anal reconstruction. 通过肌肉移植代替肛门括约肌的术式主要有(1)股薄疯移植肛门重建术,'(2)臀大肌移植肛门重建术。 By transplantation of the anal sphincter muscle surgical have primary (1) and gracilis graft anal reconstruction insane, 'anal reconstruction (2) gluteus maximus transplantation. 以上手术肛门功能的恢复并不理想,且使患者经受了较大的手术创伤。 Restore or more surgical anal function is not ideal, and subjecting the patient to a larger surgical trauma. 所以多年来没有在临床上广泛应用。 So over the years is not widely used in clinical practice. 另一类就是设计应用人工肛门括约肌假体置入盆底肛门部位。 Another type of application is the design of artificial anal sphincter prosthesis implantation pelvic floor anal area. 1995年浙江大学凌保明等提出了"原位人工肛门初步研究"的构想,主要由fe橡胶材料制成一个类盆腔装置。 In 1995, Zhejiang University Lingbao Ming put forward "in-situ artificial anus preliminary study" concept, mainly by rubber material fe a class pelvic device. 由人工囊体和夹片、拨销构成,直肠从囊体穿过- .囊体类似于直肠壶腹部,夹片拨销位于囊体下部,用手工操作来控制肛门的开闭。 Artificial balloon and a clip, constituting the deadbolt, rectal balloon through the - like rectal ampulla capsule, the capsule is located deadbolt clip lower portion thereof, with a manual operation to control the opening and closing of the anus. 2001'年西安医科大学也有人提出了一个类似装置,是由金属材科构成,没有动物试验及临床应用的报道。 2001 'Xi'an Medical University has also been proposed a similar device is composed of a metal timber division, there is no report of animal experiments and clinical application. l"6年国外报道了"人工肛门括约肌装置治疗严重肛门失禁,是一个袖套式的肛管套管装置,意.大利罗马:那不勒斯等四家医院对28例患严重肛门失禁的女性患者施行"人工肛门括约肌"置入术,并发症有肛管腐蚀、坏死、感染、疼痛,伤Cl裂开等。 l "6 years of foreign reports of the" artificial anal sphincter to treat severe incontinence device is a sleeve-like anal cannula device, Rome, Italy: Naples Hospital and three other female 28 patients suffering from severe anal incontinence purposes "artificial anal sphincter" implantation, complications anal corrosion, necrosis, infection, pain, wound dehiscence Cl. 结论是四分之三的患者排便、失禁情况有所改善,但是早期感染^直 It concluded that three-quarters of patients with bowel incontinence situation has improved, but early infection ^ straight

肠腐蚀等并发症仍是急需解决的问题。 Intestinal complications such as erosion remains an urgent problem. 2003年上海儿童医院施成仁等ii拟 2003 Shanghai Children's Hospital Shicheng Ren et ii proposed

制作"人工肛门括约肌"装置,对12例犬作了实验,.但未见临床报道。 Production of "artificial anal sphincter" device, made of 12 cases of dog experiments, but no clinical reports. 综上所述,查阅1985—2005年关于人工肛门的各类报道文章一千多篇,各种手术类型数十种,由于控制排便不理想、手术创伤大等缺陷,没有一种方. In summary, the review 1985-- 2005 kinds of artificial anus article reports on more than a thousand articles, dozens of various types of surgery because of bowel control is not ideal, surgeries and other defects, none of the party.

法可在临床广泛推r应用。 R push method can be widely used in clinical.

-发明内容 - SUMMARY

i发明目的是提供一种即符合生理要求,又有效控制排便,与周围组织考排斥,无挤压,不影响血运,不造成肠壁坏死感染的机械性人造肛门。 i that is the purpose of the invention is to provide a physiological requirements, and effective control bowel movements, and the surrounding tissue rejection test, no compression, does not affect the blood supply, causing no mechanical artificial anus intestinal necrosis infection.

本植入式人造肛门,由控制系统和人工肛垫两部分构成;肛垫由支架和三个液囊组成;支架由三根细管和两个圆环构成一个带三根长臂Ap柱 This implantable artificial anus, and the control system is composed of two parts, artificial anal cushions; anal cushions by the carrier fluid and three sacs; holder of three rings constituting the two capillary tubes and a long arm with three columns Ap
