Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a device for cleaning contents in a digestive tract.
Background
The gastrointestinal endoscope is a common medical examination and treatment means, can carry out fine examination on the gastrointestinal tract and carry out various minimally invasive treatments, and has very wide clinical application. The current guidelines of various countries already take gastrointestinal endoscopy as an important part of physical examination, and can be used for screening early cancers of the gastrointestinal tract, such as early cancers of the gastrointestinal tract, polyps of the gastrointestinal tract, gastrointestinal hemorrhage and other diseases, and can be solved by a minimally invasive treatment mode under an endoscope. However, there is an important prerequisite for gastrointestinal examination and treatment, which is to ensure the cleanness of the examined part, but in clinical practice, there are various reasons for insufficient preparation for cleaning the digestive tract. The following cases are roughly classified:
1. when the alimentary canal bleeds greatly, the field of vision under the scope can seriously be influenced to a large amount of blood clots in the stomach to can't find the bleeding point and carry out subsequent treatment, the incidental suction function of scope can't suck away the blood clots, and clinical routine's processing scheme is with some medicines that promote the peristalsis of stomach, promotes the blood clots and excretes, or in the art once and again get the blood clots in vitro or send into the duodenum, often the effect is not good like this operation, wastes time and energy moreover.
2. The obstruction of the digestive tract is accompanied by the retention of a large amount of food in the esophagus and the gastric cavity, and a large amount of food residues are remained in the gastric cavity and the esophageal cavity due to various reasons such as cardia achalasia, pylorus obstruction or duodenum stricture, so that the detection cannot be carried out, and the subsequent treatment of removing the obstruction and carrying out pathological excision under an endoscope is influenced. The conventional treatment scheme is to forbid food drinking for a long time or to suck by using a gastric tube, but the scheme cannot realize immediate treatment, if food residues are found in the operation, the operation is often stopped, the next time is arranged, the examination or treatment is carried out, the optimal time of the treatment is delayed, and food retention is found or cannot be cleaned after fasting sometimes.
3. Without fasting or bowel preparation according to established protocols, these patients often find that there is a lot of food or fecal debris in the gastrointestinal tract during examination of the gastrointestinal tract, and thus do not perform an adequate examination. This may affect the quality of the examination or only change the time for re-examination, which increases the burden on the patient himself, and also unnecessarily wastes medical resources.
In the above cases, food residue, fecal debris, blood clots, etc. present in the digestive tract are collectively referred to as digestive tract contents. When gastrointestinal endoscopy or treatment is performed, if a large amount of contents exist in a lumen, thorough examination cannot be performed, and a lesion, a bleeding part, an obstructed part, and the like cannot be found, so that the contents need to be removed, and if the contents are not removed, secondary endoscopic surgery or examination can be performed.
Therefore, if the contents in the alimentary canal can be effectively removed under the endoscope, the efficiency of endoscopic examination or treatment can be improved, the risk of re-examination or treatment can be reduced, the pain of the patient can be reduced, the operation and anesthesia cost of the patient can be reduced, and the burden of the patient can be reduced.
