Description
Technical Field
The invention relates to a duodenoscope direct-viewing auxiliary device, and belongs to the technical field of medical instruments.
Background
The duodenoscope is mainly used for a series of operations related to retrogression pancreaticocholangiography under an endoscope, is a side view mirror with a backward observation angle of 105 degrees, and has higher difficulty in operation compared with a common gastrointestinal endoscope. Endoscopic Retrograde Cholangiopancreatography (ERCP) is a technique in which a duodenoscope is inserted into the descending part of the duodenum to find the papilla of the duodenum, a contrast catheter is inserted into the opening of the papilla from a biopsy channel, and a contrast medium is injected into the opening of the papilla to perform X-ray radiography to display the cholangiopancreatography. Because ERCP does not need to be operated, the trauma is small, the operation time is short, the complication is less than that of the surgical operation, the hospitalization time is greatly shortened, and the ERCP is popular with patients. ERCP has achieved great clinical success in short decades and has become an important treatment for pancreatic and biliary diseases today. The wound can be quickly recovered with little wound while the treatment effect is ensured, and the sequela is almost avoided, so that the wound of a patient subjected to a surgical operation is avoided, and a large amount of national social medical resources are saved.
However, the ERCP-related surgery is the surgery with the greatest difficulty in endoscopic surgery, the longest learning curve and the most serious related complications. The reason is that the used operating mirror is a side view mirror, so that the front view of the duodenoscope cannot be seen directly, the difficulty of an operator in entering the mirror is greatly increased, and the operating mirror is not beneficial to being mastered by a beginner. The perforation in the operation often occurs because the side view mirror can not observe the front visual field, so that the diameter of the mirror body is directly pushed to penetrate through the alimentary canal (mainly duodenum), or the mirror body can not be well adjusted due to the limited visual field when the duodenoscope is straightened, so that the mirror body moves relative to the intestinal wall to cause perforation. The operation of a duodenoscope is therefore quite different from other endoscopes, which are rather unfriendly to the novice, with the associated complications of a large number of perforations. Therefore, the technical field needs to develop a device for assisting direct viewing of the duodenoscope to help the duodenoscope to enter the endoscope, the device can greatly improve the efficiency and the learning curve of the duodenoscope operation, and the incidence rate of perforation complications is reduced.
