The invention discloses a real-time intestinal tract cleanliness scoring system and method based on artificial intelligence. By adopting the system and method, bowel preparation quality examined by aclinical colonoscope is monitored in real time, and scoring display is carried out at a client; and the constituent ratio of each score and the cleanliness of an examined intestinal segment within each 30 s are represented. On one hand, the bowel preparation quality condition of a patient operated by a physician can be more objectively and directly expressed in a quantitative manner, and the workload and scoring errors of endoscopic physicians are reduced, so that the error evaluation of endoscopic examination quality is reduced and the interval of reexamination of colonoscope examination isrecommended; on the other hand, medical institutions can more objectively and directly know about the bowel preparation quality, so that the quality control work can be done effectively, the intestinal tract cleaning quality is rapidly improved, the adenoma detection rate is reduced, and early detection and early treatment of precancerous lesions of intestinal tracts are realized; and more importantly, the development of the system facilitates scientific inquiry for subsequent influences on bowel preparation schemes by different intestinal tract preparations.

This invention relates, e.g., to a composition comprising two or more of: (a) N-acetylcysteine and/or (b) simethicone and/or (c) a docusate salt. In one embodiment of the invention, the amounts of (a) and/or (b) and/or (c) are effective, when the composition is administered into a colon of a subject undergoing colonoscopy, to cleanse a region of the colon in the visual field of the colonoscope so that the region contains no adherent stool or intestinal secretions obscuring the visual field. Methods for using this or other compositions of the invention, e.g. to cleanse the colon of a subject in order to enhance visualization of the colon during a colonoscopy, are also described, as are kits for carrying out methods of the invention.

A guide and method for tilting a colonoscope in the rectum leftward toward the descending colon to advance the colonoscope through the colon during colonoscopy. The guide comprises a rigid elongated body member and a handle attached to or integral with the body member. The body member has an insertion length selected so as to not be inserted past the patient's rectum. The body member can be curved or tubular to better engage the colonoscope. A soft liner can be utilized to protect the endoscope during use. Preferably, the body member has a semi-circular cross-section with a flexible inner tubular member attached thereto that receives the endoscope. A longitudinal slot facilitates loading the endoscope into the tubular member. In another embodiment, the body member comprises upper and lower rigid body members connected by an engaging mechanism. The user tilts the colonoscope with the guide to minimize or avoid sigmoid looping.

The invention discloses a colonoscope handle operator for assisting a doctor in colonoscopy. A poking wheel driving mechanism, a handle fixing mechanism, a biopsy forceps closing mechanism and a biopsy forceps conveying mechanism are arranged on a U-shaped supporting plate; the handle fixing mechanism is used for fixing the colonoscope handle on the handle fixing mechanism; and a colonoscope thumbwheel is tightly attached to the inner side of a thumb wheel shell. A doctor drives the motor to control the rotating direction and angle of a poking wheel; the motor and the thumb wheel shell are driven by a synchronous belt; the accuracy of the rotating angle of the thumb wheel is ensured; the biopsy forceps conveying mechanism can ensure that biopsy forceps wires are conveyed into a biopsy channel; the biopsy forceps closing mechanism can control the opening and closing of the biopsy forceps tip. The operator can replace a traditional mode of manual impeller operation of a doctor to solvea problem that muscles of fingers and shoulders of the doctor are injured by long-time impeller stirring; meanwhile, a traditional mode of assisting the doctor in operating conveying and opening and closing of biopsy forceps by an assistant is replaced, and the purpose that the doctor independently completes colon examination and polyp extirpating work is achieved.

The invention discloses a detection method for judging whether colonoscopy is complete or not based on image recognition. The method comprises the steps that in the whole enteroscopy process, a completeness detection model is used for conducting average gray value detection on four corners of each frame of image in enteroscopy video stream, and if the Boolean value output by a preset number or more of continuous frames of one corner is 0, a prompt that completeness detection is not conducted is output. According to the detection method for judging whether colonoscopy is complete or not based on image recognition, the problem that a doctor does not completely inspect the interior of the intestinal tract in the colonoscopy process can be solved, so the colonoscopy quality of an operator is improved, and the missed lesion diagnosis rate of colonoscopy is reduced.

The invention discloses a method for increasing the adenomatous polyp detection rate of a colonoscope based on deep learning. The method comprises the following steps: dividing a video stream transmitted by an enteroscope lens in an operating table into two parts, transmitting one part of the video stream to an operation platform of a doctor, preprocessing the other part of the video stream, and sending the preprocessed video stream to a polyp detection model embedded into an enteroscope operating system for identification; allowing the polyp detection model to detect whether polyps appear ineach frame of image and the appearing probability of polyps; and returning a detection result of the polyp detection model to the operation platform of the doctor for displaying, and if polyps appearin the video stream, framing the polyps for prompting. By means of an artificial intelligence deep neural network, polyps appearing in a lens in the operation process of colonoscopy can be automatically detected, a polyp recognition rate in colonoscopy examination process is increased, and therefore, the adenomatous polyp detection rate is indirectly increased.
