The embodiment of the invention discloses a verification method, device and equipment for ERCP selective bile duct intubation and a medium. The method comprises the following steps: segmenting and marking a first ERCP image containing a duodenal large papilla to obtain a duodenal large papilla area and an opening area of the duodenal large papilla; determining the bile duct axial direction of the duodenum large papilla according to the duodenum large papilla area and the opening area; segmenting and marking the second ERCP image containing the duodenal large papilla, and predicting an incision knife intubation direction of the duodenal large papilla according to the generated central line of the incision knife area; and verifying the intubation direction of the incision knife according to the axial direction of the bile duct so as to verify the selective bile duct intubation. According to the method, the intubation position and direction are accurately recognized through the image segmentation technology, meanwhile, the intubation direction of the incision knife is verified through the axial direction of the bile duct, then the wrong intubation direction of an endoscope physician is corrected in time, and the efficiency and accuracy of selective bile duct intubation are greatly improved.
Description
technical field [0001] The invention relates to the field of medical auxiliary technology, in particular to a verification method, device, equipment and medium for ERCP selective bile duct intubation. Background technique [0002] Endoscopic retrograde cholangiopancreatography (ERCP) is to insert an endoscope into the descending part of the duodenum to find the nipple of the opening of the pancreaticobiliary duct, insert a contrast catheter through the biopsy hole, and inject an iodine contrast agent for X-ray examination a method of At present, ERCP surgery has become an important method for the treatment of various biliary and pancreatic diseases. Among them, selective bile duct cannulation (selective bile duct cannulation, SBC) is the basis and key to the success of ERCP surgery, that is, through accurate identification of the ampulla of the duodenum and intubation with a guide wire incision knife, the specific method is as follows: The incision knife or radiography cat...
