Description
Technical Field
The utility model relates to an oropharynx protection device for endoscopic minimally invasive diagnosis and treatment, and belongs to the technical field of medical instruments.
Background
In recent years, the incidence of digestive tract diseases and tumors gradually rises, and new treatment techniques are also developed. Endoscopes are used not only for examination but also for treatment of these diseases, and thus demand for endoscopic diagnosis and treatment is increasing. Endoscopic diagnosis and treatment have been developed from simple polyp removal, drug injection and foreign body extraction to effective radical treatment of early cancer; moreover, the types of the operation cover all the parts of the gallbladder, the pancreas, the esophagus, the stomach and the large intestine and the small intestine, and the operation blind areas are basically cleared. The early stage tumors of the digestive tract, such as gastric cancer, esophageal cancer, pancreatic cancer and the like, can be diagnosed and radically treated by applying various advanced endoscopic minimally invasive techniques without an open surgery. The different digestive endoscopy treatment means of the day and night frequently breaks through the forbidden operation area, and brings new hopes to patients, such as painless gastroscopy, enteroscopy, enlarged dyeing endoscopic early cancer fine examination, endoscopic stomach and small intestine ostomy, ultrasonic endoscopic fine needle puncture, endoscopic hemostasis and foreign body extraction, ligation and sclerosing agent treatment of esophageal variceal bleeding, expansion of digestive tract stenosis or stent treatment, cardiac achalasia balloon expansion treatment or POEM operation, Endoscopic Submucosal Dissection (ESD), endoscopic full-layer resection (EFR), endoscopic tumor resection (ESE), endoscopic submucosal tunneling technology (STER), endoscopic sphincterotomy (POEM), submucosal tunneling endoscopic isolation and dissection (STESD), endoscopic radio-dissection (ERI), double-lens treatment and the like. Compared with the traditional operation treatment, the minimally invasive treatment under the gastroscope enters through a natural cavity without additionally manufacturing an incision on the skin of the body surface, has the characteristics of small wound and quick recovery, has higher psychological and physiological bearing degrees of patients, and is easy to popularize. The minimally invasive treatment under the gastroscope is particularly suitable for resection of early cancer of the upper digestive tract and submucosal tumors (leiomyoma, interstitial tumor within 2CM and the like), the cure rate is almost the same as that of the traditional surgical operation or even better than that of the surgical operation, the complication incidence rate is obviously reduced, the normal physiological structure of the wall of the digestive tract tube is not changed, the original function is kept, and the minimally invasive treatment is more easily accepted by patients; more importantly, the hospital stay time can be obviously shortened, the medical cost is saved, and the satisfaction degree of the public on the medical service is improved. The endoscope treatment technology can fully embody the superiority of minimally invasive surgery and has great social benefit.
With the development of the continuously developed endoscopic diagnosis and treatment technology, medical staff also needs to face some new problems:
1. when painless gastroscope diagnosis and treatment are carried out, a patient is in an anesthesia state or a certain special body position, the gastroscope is difficult to insert into the upper section of the esophagus, and can be inserted repeatedly, so that the mucous membrane of the throat is easy to be damaged or hematoma is easily formed;
2. when the sharp foreign bodies in the upper digestive tract are taken out under a gastroscope, the inevitable and obvious mucosal injury and even digestive tract perforation are easily caused.
3. When taking out the pathological specimen of excision under the gastroscope, drop easily in the oral cavity through oropharynx portion, under the circumstances of not having trachea cannula anesthesia, increased and taken out the degree of difficulty and have and fall into the trachea and cause the risk of suffocation.
4. For patients with acute upper gastrointestinal hemorrhage, the gastric cavity blood clots and liquid retention substances cannot be quickly sucked and cleaned, so that the patients may miss the optimal treatment opportunity and cause aspiration to cause serious complications in the gastroscope diagnosis and treatment process.
5. When food retention in the gastric cavity or gastroliths taken out in blocks are brought out from the esophagus, the gastroliths cannot be collected by other surgical instruments due to special properties of the gastroliths, are sucked only by the front end of the endoscope and easily fall into the oral cavity when passing through the entrance of the esophagus, so that the operation time is prolonged, and the asphyxia caused by mistaken suction can be caused.
