Abstract
A capsule endoscope feeding device comprises a gastroscope tube, a connection sleeve, a fixing wire and a control wire, wherein the small end of the connection sleeve is arranged on the gastroscope tube, the inner diameter of the larger end is slightly larger than the outer diameter of a capsule endoscope, the length of the connection sleeve is two thirds of the length of the capsule endoscope, and the capsule endoscope is arranged in the large end; the fixing wire is arranged on the large end of the connection sleeve to fix the capsule endoscope; and the control wire penetrates through the gastroscope tube to be connected with the fixing wire. According to the capsule endoscope feeding device, the capsule endoscope left in the alimentary canal or the stomach can be conveniently and quickly taken and fed into the duodenum; for a patient having difficulty in swallowing the capsule endoscope, the capsule endoscope outside the body can be quickly fed into the duodenum; the capsule endoscope feeding device can release the capsule endoscope reliably, is compact in structure and low in manufacture cost, and can be used for the existing universal capsule endoscope.
Description
Technical field
The present invention relates to a kind of medical appliance, especially for the capsule endoscope implanting device of digestive tract examining.
Background technology
Small intestinal is the digestive tract tube chamber that connects between pylorus and the ileocecal valve, can be for the conventional Gastrointestinal endoscope inspection with the latter end ileal segment except more than the duodenum section of falling, other parts are the most difficult parts in the whole gastrointestinal examination, again because of small intestinal length long (3.35～7.85m), be free on intraperitoneal and formed multiple compound intestinal loop by the mesentery constraint, traditional inspection technology is very limited.The method of many small bowel examinations, as the barium meal examination of x-ray small intestinal, enteroscope, radioisotope scanning and angiography etc. all exist low, the location of diagnosis positive rate and qualitative inaccurate, the patient suffering is large or belong to traumatic inspection with shortcomings such as complication when checking.Capsule endoscope is as a kind of novel small bowel examination method, and general size is 11mm * 27mm, is similar to the pill of the capsule shape that patient clinically takes, so the title capsule endoscope.This Novel endoscope shell is made by smooth macromolecular material, built-in miniature video camera and video signal transmitter, and simultaneously from charged pool, battery life can be kept microcam in the capsule and video signal transmitter continuous firing 7～8 hours.After capsule is swallowed by the people, mobile in digestive tract by gastral wriggling, obtain and transmission video signal to the receiving system of person under inspection's body surface, the patient can be at the imaging data that has no to obtain in the painful situation whole small intestinal.Although capsule endoscope has very high diagnostic value to small intestinal inflammation, the disease such as hemorrhage, many defectives are also arranged, one of them more common shortcoming is to be subjected to the impact of stomach, small intestinal operation (wriggling) larger after capsule endoscope is swallowed, and battery life is limited.Slow or when blocking arranged when stomach, esophageal peristalsis, capsule can rest in stomach or the esophagus for a long time, the energy content of battery is consumed too much in the time of can not entering small intestinal or enter small intestinal, can't make a video recording to whole small intestinal again, thereby cause small intestinal not finish checking and occur failing to pinpoint a disease in diagnosis.Another more rare shortcoming is that capsule endoscope is compared with the pill of the clinical capsule shape of taking, volume is still bigger than normal, few some patients were (mainly being child patient) lest fearing or bottleneck throat muscle spasm and can not swallowing in the esophagus, causes checking and can not carry out when swallowing.
When above-mentioned situation occurring, need the doctor with snare (or basket) capsule endoscope to be sent into the duodenum section of falling by gastroscope and scope, increased patient's misery, simultaneously consuming time, take a lot of work, and possible unsuccessful.In addition, capsule endoscope is very expensive at present, in case check unsuccessfully, causes easily producing contradiction between patient, hospital, distributor and the manufacturer.
For above problem, at present existing Patents bibliographical information can use special-purpose propelling movement apparatus auxiliary lower to the capsule endoscope duodenum of making a gift to someone at gastroscope, but this kind method still has a lot of defectives: at first need to use complicated apparatus, operation is complicated, and only for the smooth patient of swallowable capsule scope, as previously mentioned, the capsule endoscope shell is made by smooth macromolecular material, most of patient can both swallow smoothly and enters duodenum during clinical practice used, therefore for the adult, do not need the conventional pusher that uses to send into duodenum.For true child and the few part adult patient that needs Capsule Endoscopy and can not swallow voluntarily, also seldom use clinically at present pusher, method commonly used is to catch capsule endoscope with basket first, settle hyaline cap at the gastroscope head end, have the basket of capsule endoscope to be fixed on the duodenum of making a gift to someone after acquisition is supported on the hyaline cap on net.Capsule endoscope is stranded in the patient of esophagus or gastric and for swallowing, pusher directly pushes duodenum with it after can not settling in vivo capsule endoscope, need be got capsule by gastroscope first external, are reinstalled on the pusher and just can send into duodenum.And the capsule endoscope shell is very smooth, get the capsule endoscope that is detained external even more difficult than the duodenum of directly making a gift to someone by gastroscope, so the actual use value of pusher is very limited.And at present clinically for the capsule endoscope that is stranded in esophagus and gastric, generally be under the gastroscope mediation, the duodenum of making a gift to someone after adopting snare or basket that capsule is entangled, as previously mentioned, because shell is very smooth, snare or basket all are not easy to catch capsule, even after catching, also can only laterally catch the middle part of capsule endoscope shell, less or spasm occurs when pylorus, or gastric antrum becomes hook-shaped when crooked, and capsule is very large by the resistance of pylorus, the steel wire of snare or basket can not resistance and is bent, cause capsule endoscope or slippage not to occur by pylorus, so the gastroscopist need require considerable time and effort and finish this work, pressure is very large during operation, gastroscope time of staying in patient body while is also longer, has increased patient's misery and risk.
CN200480028555.1 discloses a kind of gastrointestinal tract examining apparatus, comprise and to carry out the capsule endoscope that digestive tube checks, flexual body, be inserted through the flexual rope form parts in the described body, connecting portion is set in capsule endoscope, be linked to removably by the rope form parts on the connecting portion of capsule endoscope, link separably body and capsule endoscope, need to make linking part at capsule endoscope, make the structure complicated, need special the making, increase and produced cost, affect simultaneously the smooth smooth of capsule endoscope surface, need cut off connection rope when dismounting separates or destroy linking part, might need not have when separation generation connection rope cut-out or linking part to destroy, also may there be when separation can not cut off connection rope or destruction linking part at need, therefore, this device reliability is poor, inconvenient operation.And, use this device can not pick up the capsule endoscope that is trapped in stomach or the digestive tract.
Summary of the invention
