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 relates to the technical field of gall-stone extraction, in particular to a gall-stone extraction device with grabbing and dosing matched and a using method thereof.The gall-stone extraction device comprises a protective tube and a dosing tube slidably mounted in the protective tube, a pushing ring is fixed to the end of the dosing tube, and the dosing tube is sleeved with a first spring abutting against the pushing ring; the grabbing mechanism is arranged on the protective tube and connected with the dosing tube, and a plurality of grabbing plates which are circumferentially distributed at equal intervals are connected to the grabbing mechanism; the piston cylinder is fixedly mounted on the protective tube, and a synchronous dosing mechanism is arranged in the piston cylinder; and the rotating ring is rotationally installed on the medicine feeding pipe and matched with the synchronous medicine feeding mechanism, and a rotating guide assembly connected with the rotating ring is arranged in the protection pipe. When the gall-stone is grabbed, medicine feeding treatment can be conducted synchronously, and when the grabbed gall-stone is taken out and released, medicine feeding treatment can be conducted synchronously; and the liquid medicine in the piston cylinder cannot be discharged.

The invention relates to the technical field of microorganisms, in particular to a Cristinia microphylla microbial agent and application thereof in preparation of products for preventing gall-stone. The preparation method of the microbial agent comprises the following steps: (1) dissolving a PYG culture medium in a solvent, sterilizing to obtain a sterilized culture medium, adding a vitamin K1 solution and a hemin solution, and uniformly mixing to obtain an improved PYG liquid culture medium; (2) inoculating the improved PYG liquid culture medium with the Cristinia parvata and carrying out anaerobic culture to obtain a culture solution; and (3) centrifuging the culture solution, adding normal saline, and uniformly mixing to obtain the microbial inoculum. On the basis of case contrast research and animal experiments, the formation of the gall-stone is prevented and the blood fat level is regulated by using the interference of the Cristinia microphylla, and a new thought and a new method are provided for a gall-stone prevention strategy.

The invention discloses a gall-stone disease risk prediction method and system based on oral flora, and belongs to the technical field of gall-stone disease risk prediction. The method comprises the following steps: collecting samples, wherein the samples comprise oral bacterial species and abundance of a gall-stone patient group and a healthy control group; comparing the gall-stone patient group sample with the healthy control group sample, and determining the relevance between the oral flora and the gall-stone disease risk; selecting a plurality of oral bacterial species as input feature species of the prediction model; and inputting the feature value corresponding to the input feature type of the to-be-tested person into the random forest model to predict the gall-stone disease risk of the to-be-tested person. According to the method, the oral bacterial species and abundance in the sample can be obtained through 16S rRNA gene sequencing only by collecting the saliva sample of the to-be-detected person, and compared with an existing prediction model, the sample collection difficulty is greatly reduced, and popularization is more facilitated.

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.
