技术领域technical field
本发明涉及肠镜检查和治疗领域，具体涉及一种肛肠插管。The invention relates to the field of colonoscopy examination and treatment, in particular to an anorectal cannula.
背景技术Background technique
肠镜检查是利用一条长约140CM可弯曲，末端装有一个光源带微型电子摄影机的纤维软管，由肛门慢慢进入大肠，以检查大肠部位之病变，肿瘤或溃疡，如有需要可取组织检验或行大肠息肉切除，实现检查和治疗。Colonoscopy is to use a flexible fiber tube with a length of about 140 cm, a light source and a microelectronic camera at the end, slowly enter the large intestine from the anus, to check the lesions, tumors or ulcers in the large intestine, and take tissue tests if necessary Or perform colorectal polypectomy for examination and treatment.
当肠镜管进入肠道内的时候，大多从肛门入镜，肠镜管的端部会先向前端的肠内先灌入一点气体或水，使前端的肠壁张开，然后将肠镜管往前塞入；肠镜管每向前塞入一次之前，都需要向肠内灌入气体。由于气体灌入肠道内之后，病人会有涨气感，会有放屁的感觉。病人需要利用括约肌收缩将肛门夹紧肠镜管，防止肠道内的气体逸出，也避免肠镜管被肠道内的气压推出肠道而导致肠镜检查失败。由于肠镜检查的时间一般在20分钟至40分钟左右，括约肌长时间收缩会产生疲劳，所以病人相对来说比较辛苦，而且括约肌收缩夹紧肠镜管之后，还会增加肠镜管与肛门之间的摩擦阻力，不便于医生将肠镜管继续塞入病人的肛门。When the colonoscope tube enters the intestinal tract, it usually enters the scope from the anus, and the end of the colonoscope tube will first inject a little gas or water into the intestine at the front end, so that the intestinal wall at the front end will open, and then the colonoscope tube will go into the intestine. Forward insertion; each time the colonoscope tube is inserted forward, the bowel needs to be insufflated with gas. After the gas is poured into the intestinal tract, the patient will feel bloated and feel like farting. The patient needs to use the contraction of the sphincter to clamp the anus to the colonoscope tube to prevent the gas in the intestine from escaping, and also to prevent the colonoscope tube from being pushed out of the intestinal tract by the air pressure in the intestine, resulting in the failure of the colonoscopy examination. Since the time of colonoscopy is generally about 20 minutes to 40 minutes, the sphincter contraction will cause fatigue for a long time, so the patient is relatively hard, and after the sphincter contraction clamps the colonoscope tube, it will also increase the distance between the colonoscope tube and the anus. The frictional resistance between them is not convenient for the doctor to continue to insert the colonoscope tube into the patient's anus.
另外，做肠镜检查的病人中，有不少人的年龄相对较大，这部分病人的括约肌收缩能力较弱，已经没有能力将肠镜管夹紧。因此这部分病人在做肠镜检查的时候需要经过多次尝试才能将肠镜管插入肛门内，而且在肠镜管继续向前塞入的过程中，由于括约肌的收缩力不够，，会导致肠镜管肠道内的气体或液体逸出，不仅不利于肠镜管的继续塞入，进而也导致检查操作的时间较长，病人所忍受的痛苦更大，还会甚至还会导致操作的医生失去耐性；另外肠道内的气体从肛门处逸出的时候还会发出响声，另病人和医生非常尴尬，客观上也会影响医生的心情，从而影响到检查和治疗的效果。In addition, among the patients undergoing colonoscopy, many of them are relatively older, and the sphincter contractility of these patients is weak, and they are no longer able to clamp the colonoscopy tube. Therefore, these patients need to go through many attempts to insert the colonoscope tube into the anus during colonoscopy, and in the process of continuing to insert the colonoscope tube forward, due to insufficient contraction of the sphincter, it will cause intestinal The escape of gas or liquid in the intestinal tract of the endoscopic tube is not only unfavorable for the continued insertion of the endoscopic tube, but also leads to a longer inspection operation time, greater pain for the patient, and even causes the operating doctor to lose Patience; In addition, when the gas in the intestinal tract escapes from the anus, it will make noises, which makes the patient and the doctor very embarrassed, and objectively affects the mood of the doctor, thus affecting the effect of examination and treatment.
