This invention discloses an intelligent identification method for hepatobiliary and renal stones based on ultrasound images, belonging to the field of stone identification technology. The method includes the following steps: acquiring an ultrasound image to be detected and marking it as a real-time detection image; obtaining real-time detection grayscale values ​​based on the real-time detection image; obtaining organ grayscale thresholds based on ultrasound images in a database; obtaining real-time organ regions based on the real-time detection grayscale values ​​and organ grayscale thresholds; constructing real-time stone detection values ​​based on the real-time organ regions; obtaining historical normal boundary values ​​based on ultrasound images in a database; obtaining stone boundary thresholds based on the historical normal boundary values; and determining whether gallstones are present based on the real-time stone detection values ​​and stone boundary thresholds. This invention addresses the problem that existing stone identification technologies suffer from poor accuracy due to significant noise in ultrasound images.

The present invention relates to an artificial bile duct comprising ursodeoxycholic acid (UDCA), and due to comprising UDCA, the artificial bile duct of the present invention is effective in improving differentiation into cholangiocytes and preventing formation of bile stones.

The invention discloses a gall-stone removing device which comprises a stone removing holding rod, a flushing assembly is arranged in the stone removing holding rod and can flush an operation area in the stone removing process, a stone removing assembly is arranged at the front end of the stone removing holding rod and used for clamping stones, and a stone crushing module is arranged at the front end of the stone removing holding rod and used for crushing the stones. The lithotripsy module is a miniature ultrasonic lithotripsy device and can conduct lithotripsy while clamping the calculus, a collecting assembly is arranged on the surface of the front end of the calculus taking holding rod, the collecting assembly can collect calculus fragment residues in a contractible and expandable mode, and the risk of postoperative complications is reduced; the device integrates the functions of flushing, calculus removing, calculus crushing and collecting, meets the clinical complex and changeable operation requirements in all directions, and has obvious advantages compared with a traditional calculus removing device with a single function.
