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 connecting between pylorus and ileocecal valve, except the duodenum section of falling is above and latter end ileal segment can be conventional Gastrointestinal endoscope inspection, other parts are the most difficult parts in whole gastrointestinal examination, grow (3.35～7.85m), be free on intraperitoneal and formed multiple compound intestinal loop by mesentery constraint because of small intestinal length again, 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, patient suffering is large or belong to traumatic inspection with shortcomings such as complication while 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 takes clinically, therefore claim capsule endoscope.This Novel endoscope shell is made up of smooth macromolecular material, built-in miniature video camera and video signal transmitter, and simultaneously from charged pool, battery life can maintain microcam in capsule and video signal transmitter continuous firing 7～8 hours.Capsule moves in digestive tract by gastral wriggling after being swallowed by people, obtain and transmission video signal to the receiving system of person under inspection's body surface, patient can be at the imaging data that has no to obtain painful in the situation that whole small intestinal.Although capsule endoscope has very high diagnostic value to small intestinal inflammation, the disease such as hemorrhage, also there are many defects, one of them more common shortcoming is after capsule endoscope is swallowed, to be subject to the impact of stomach, small intestinal operation (wriggling) larger, and battery life is limited.When stomach, esophageal peristalsis are slow or have the time of blocking, capsule can rest in stomach or esophagus for a long time, when can not entering small intestinal or entering small intestinal, the energy content of battery is consumed too much, cannot make a video recording to whole small intestinal again, thereby cause small intestinal can not complete check 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, when few some patients were (being mainly child patient) is swallowed, can not swallow in esophagus because of fear or bottleneck throat muscle spasm, cause checking and can not carry out.
When occurring when above-mentioned situation, need doctor by gastroscope and scope for snare (or basket) capsule endoscope is sent into the duodenum section of falling, increased patient's misery, the while is consuming time, take a lot of work, and likely unsuccessful.In addition, capsule endoscope is very expensive at present, once check unsuccessfully, easily causes producing contradiction between patient, hospital, distributor and manufacturer.
For above problem, at present existing Patents bibliographical information can use the special propelling movement apparatus duodenum of under gastroscope is auxiliary, capsule endoscope being made a gift to someone, but this kind of method still has a lot of defects: first need to use more complicated apparatus, operate more complicated, and only for the patient of swallowable capsule scope smoothly, as previously mentioned, capsule endoscope shell is made up of smooth macromolecular material, during clinical practice uses, most of patient can swallow smoothly and enter duodenum, therefore for adult, do not need the conventional pusher that uses to send into duodenum.The child that can not swallow voluntarily for really needing Capsule Endoscopy and few part adult patient, also seldom use clinically at present pusher, conventional method is first to catch capsule endoscope with basket, settle hyaline cap at gastroscope head end, net is had the basket of capsule endoscope to be fixed on hyaline cap to obtain the duodenum of making a gift to someone after supporting.And for swallowing, capsule endoscope is stranded in the patient of esophagus or gastric, pusher after can not settling in vivo capsule endoscope directly pushes it into duodenum, need first by gastroscope, capsule is got external, be reinstalled in and on pusher, just can send into duodenum.And capsule endoscope shell is very smooth, by gastroscope, the capsule endoscope of delay is got external even more difficultly than the duodenum of directly making a gift to someone, therefore 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 under 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 are all not easy to catch capsule, even after catching, also can only laterally catch the middle part of capsule endoscope shell, when pylorus is less or spasm occurs, or gastric antrum becomes hook-shaped when bending, 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, therefore gastroscopist's this work of need having required considerable time and effort, when operation, pressure is very large, gastroscope time of staying in patient body is also longer simultaneously, patient's misery and risk are increased.
CN200480028555.1 discloses a kind of gastrointestinal tract examining apparatus, comprise the capsule endoscope that can carry out digestive tube inspection, flexual body, be inserted through the flexual rope form parts in described body, connecting portion is set in capsule endoscope, be linked to removably by rope form parts on the connecting portion of capsule endoscope, link separably body and capsule endoscope, need on capsule endoscope, make linking part, make structure become complicated, need special making, increase and produced cost, affect the smooth of capsule endoscope surface simultaneously, when dismounting separates, need cut off connection rope or destroy linking part, connection rope cut-out or linking part likely occur in the time not needed separation to be destroyed, also may there is the time of separation can not cut off connection rope or destroy linking part at need, therefore, this device reliability is poor, inconvenient operation.And, use this device can not pick up the capsule endoscope being trapped in stomach or digestive tract.
