Multi-mode cholangiopancreatography system

Abstract

The invention discloses a multi-mode cholangiopancreatography system which comprises an image processing system, a first optical imaging system, an ultrasonic imaging system, an endoscope probe, a photoelectric slip ring component, a first optical fiber, a second optical fiber, a first electric signal line and a second electric signal line. The endoscope probe is provided with an optical probe component and an ultrasonic transducer, the photoelectric slip ring component drives the endoscope probe to rotate and comprises a rotary photoelectric coupling unit and a rotation driving device for driving the rotary photoelectric coupling unit to rotate, a photoelectric slip ring is arranged in the rotary photoelectric coupling unit, the first optical imaging system is connected with one end of the photoelectric slip ring through the first optical fiber, the other end of the photoelectric slip ring is connected with the optical probe component through the second optical fiber, the ultrasonic imaging system is connected with one end of the photoelectric slip ring through the first electric signal line, and the other end of the photoelectric slip ring is connected with the optical probe component through the second electric signal line. According to the multi-mode cholangiopancreatography system, by the aid of multi-mode (optical and ultrasonic) cooperative imaging, imaging resolution ratio and imaging depth are increased, and the system is applicable to cholangiopancreatography.

Description

technical field [0001] The invention relates to the technical field of endoscopic imaging equipment, in particular to a multimodal pancreaticobiliary imaging system. Background technique [0002] Pancreaticobiliary malignancies often originate from the endothelial cells of the pancreatic or bile ducts. Its formation is usually a dynamic process: it initially manifests as dysplasia of pancreaticobiliary epithelial cells, further infiltrates and grows into the basement membrane of the pancreaticobiliary duct, and develops into invasive adenocarcinoma after breaking through the basement membrane. During this process, the typical histomorphological changes of the pancreaticobiliary epithelium are mainly reflected in the abnormal structure and cytology. Structurally abnormal refers to the normal pancreaticobiliary epithelium is gradually replaced by a single layer of cuboidal or low columnar cells that are rich in mucinous cytoplasm, and the arrangement of epithelial cells is di...

Problems solved by technology

However, the imaging depth of these imaging techniques is relatively shallow, so the imaging ability must be projected to the location of pancreaticobiliary lesions through endoscopy
