背景技术Background technique
小肠是人体消化系统中最长的器官,成人全长约5~7米,占消化道全长的75%。小肠上端连接胃幽门,下端在右髂窝与结肠相接,可分为十二指肠、空肠和回肠三部分。由于小肠长而游离、走形迂曲重叠、处于身体较深部位,且远离口腔和肛门,小肠疾病的诊治一直是消化科医生的难题。在过去很长一段时间内,小肠远落后于胃肠道其他部位疾病的诊断。The small intestine is the longest organ in the human digestive system, with a total length of about 5-7 meters in adults, accounting for 75% of the total length of the digestive tract. The upper end of the small intestine connects to the gastric pylorus, and the lower end connects to the colon in the right iliac fossa, and can be divided into three parts: the duodenum, jejunum, and ileum. Because the small intestine is long and free, twists and turns and overlaps, is located in the deep part of the body, and is far away from the mouth and anus, the diagnosis and treatment of small intestine diseases has always been a difficult problem for gastroenterologists. For a long time in the past, the small intestine has lagged far behind in the diagnosis of diseases in other parts of the gastrointestinal tract.
小肠镜的研制及临床应用始于20世纪70年代,传统的小肠镜只能观察近侧段空肠及末端回肠,医学专家们曾尝试各种方法,但远端空肠及回肠的观察仍不能令人满意。1999年,以色列Given公司研制成功了世界上第一个可吞咽的胶囊内镜,可以对全消化道进行摄像,对小肠疾病的检出率较其他传统方法高,其无创性、无交叉感染易为病人所接受。但有其局限性,如胶囊的移动不可控制,肠道内积液可能影响对病变的观察,不能取活检行病理检查以明确病灶性质。2002年,学者山本博德与富士写真光机株式会社共同研制出双气囊电子小肠镜。它的问世与应用,将小肠疾病的诊断和治疗提升到一个全新高度。但现有小肠镜操作技术复杂,一次性检查可窥见全部小肠的几率极低,许多病人需经双侧进镜仍无法检查完全部小肠。The development and clinical application of enteroscopy began in the 1970s. Traditional enteroscopy can only observe the proximal jejunum and terminal ileum. Medical experts have tried various methods, but the observation of the distal jejunum and ileum is still not satisfactory. satisfy. In 1999, the Israeli company Given successfully developed the world's first swallowable capsule endoscope, which can take pictures of the entire digestive tract and has a higher detection rate of small intestinal diseases than other traditional methods. It is non-invasive and free from cross-infection. accepted by the patient. However, it has its limitations, such as uncontrollable movement of the capsule, accumulation of fluid in the intestine may affect the observation of the lesion, and biopsy cannot be taken for pathological examination to clarify the nature of the lesion. In 2002, scholar Yamamoto Hirode and Fuji Photo Photonics Co., Ltd. jointly developed a double-balloon electronic enteroscope. Its appearance and application have raised the diagnosis and treatment of small intestinal diseases to a new level. However, the operation technique of the existing enteroscopy is complicated, and the probability of seeing the entire small intestine in one-time inspection is extremely low. Many patients still cannot inspect the entire small intestine through bilateral endoscopy.
我们的通过对尸体解剖研究发现,人体小肠走行存在非常大的变异,如果对小肠的走行不够了解进镜的过程中极易成袢,因而能够经口完成全小肠检查的成功率不高,且与胃镜、结肠镜检查比较,因小肠走行及结构变异极大,医生在检查前及检查中均无法预知小肠的走行,术中亦无法知道内镜距回盲瓣的距离,因此存在极大的盲目性。Our research on autopsy found that there are great variations in the course of the human small intestine. If you do not know enough about the course of the small intestine, it is easy to form a loop during the process of entering the microscope. Therefore, the success rate of the whole small intestine examination through the mouth is not high, and Compared with gastroscopy and colonoscopy, the course and structure of the small intestine vary greatly, and doctors cannot predict the course of the small intestine before and during the examination, nor can they know the distance between the endoscope and the ileocecal valve during the operation, so there is a huge risk. blindness.
因此如何预知肠管的走行并指导小肠镜的进镜方向,提高小肠镜的检查效率和成功率是医学界所面临的难题。本研究意在发明一种利用肠道蠕动功能自行通过小肠,在放射线下可清楚显示小肠走行,而且可被拉入小肠镜活检孔道用以引导小肠镜检查的导丝装置。Therefore, how to predict the course of the intestinal tube and guide the direction of entry of the enteroscope to improve the efficiency and success rate of the enteroscope is a difficult problem for the medical community. This study intends to invent a guide wire device that uses the function of intestinal peristalsis to pass through the small intestine by itself, which can clearly show the course of the small intestine under radiation, and can be pulled into the biopsy hole of the enteroscope to guide the enteroscopy.

步骤二:患者服用常规导泻剂,利用肠道的蠕动作用,该引导物体2带动导丝1在肠道内向肛门方向前进,此时由于位于导丝1后端的气囊3的直径过大,气囊3会不通过胃幽门,从而固定导丝1的末端连接结构7位于胃内,引导体2经过约四小时自肛门排出,医生在此期间可通过放射线确定引导体2的位置以及导丝1经过的路线,从而使医生在小肠镜检前能够全貌了解小肠的走向和结构。Step 2: The patient takes conventional cathartics and utilizes the peristaltic effect of the intestinal tract. The guiding object 2 drives the guide wire 1 to advance in the direction of the anus in the intestinal tract. 3 will not pass through the gastric pylorus, so that the terminal connection structure 7 of the fixed guide wire 1 is located in the stomach, and the guide body 2 will be discharged from the anus after about four hours. During this period, the doctor can determine the position of the guide body 2 and the passage of the guide wire 1 through radiation. The route, so that the doctor can get a complete picture of the direction and structure of the small intestine before the small intestine endoscopy.
步骤三:小肠镜检查前用一活检钳夹持一外接丝线5的前端经小肠镜的活检孔道引入到胃中,同时保持外接丝线5的后端位于体外,活检钳在胃内将外接丝线5的前端穿过导丝1末端的连接结构7,并再次通过小肠镜的活检孔道引出体外,继而将外接丝线5的前端和后端共同固定在体外。Step 3: Before the enteroscopy, use a biopsy forceps to hold the front end of an external silk thread 5 and introduce it into the stomach through the biopsy channel of the enteroscope, while keeping the rear end of the external silk thread 5 outside the body, and insert the external silk thread 5 in the stomach with biopsy forceps The front end of the external wire 5 passes through the connection structure 7 at the end of the guide wire 1, and is drawn out of the body through the biopsy channel of the enteroscope again, and then the front end and the rear end of the external wire 5 are jointly fixed outside the body.
步骤四:用一锐器通过小肠镜活检孔道刺破气囊3并断开气囊3与导丝1之间的第一分叉丝8,使气囊3与导丝1脱离,气囊3能够经消化道排出体外,此时外接丝线5和导丝1连接为一体,并经口至肛门完整的贯穿整个消化道。小肠镜操作时,向外牵拉外接丝线5使导丝1进入小肠镜活检孔道,导丝1引导小肠镜操作,提高小肠镜检查的效率和成功率,使小肠镜检查这一复杂而难以掌控的操作变得简单易行。Step 4: Use a sharp instrument to puncture the air bag 3 through the biopsy channel of the enteroscope and disconnect the first bifurcation wire 8 between the air bag 3 and the guide wire 1, so that the air bag 3 and the guide wire 1 are separated, and the air bag 3 can pass through the digestive tract Excreted from the body, at this time the external silk thread 5 and the guide wire 1 are connected as a whole, and run through the entire digestive tract from the mouth to the anus. During the operation of the enteroscope, the external silk thread 5 is pulled outward to make the guide wire 1 enter the biopsy hole of the enteroscope, and the guide wire 1 guides the operation of the enteroscope, which improves the efficiency and success rate of the enteroscope examination, making the enteroscopy examination complicated and difficult to control. The operation becomes simple and easy.
