The present application relates to the technical field of medical demonstration tools, and specifically relates to a weight loss surgery demonstration model, which comprises a display platform and a human gastrointestinal model arranged on the display platform, a cutting position is formed on the human gastrointestinal model, a clamping mechanism is arranged on the cutting position, a control panel and an internal power supply are arranged in the display platform, the clamping mechanism and the internal power supply are electrically connected with the control terminal, and the clamping mechanism is used for simulating the cutting and closing actions of the cutting position in the surgical process. The clamping mechanism can simulate the process of cutting and closing the cutting position by surgical instruments, which facilitates the observation of the main surgical steps of sleeve gastrectomy and Roux-en-Y gastric bypass surgery. The light-emitting layer can simulate the process of food passing through different parts of the human gastrointestinal model before and after surgery, so that the process of food intake and digestion before and after surgery can be observed. In addition, the light-emitting layer can also simulate the state of common postoperative complications of the cutting position, demonstrate postoperative bleeding or fistula of the cutting position, and has a better demonstration effect.

The invention relates to the technical field of medical instruments, in particular to an anastomotic stoma reinforcing and leakage preventing device for sleeve gastrectomy, which comprises a grab handle, a control frame is fixedly connected to the top of the grab handle, a driving block is fixedly connected to the side surface of the control frame, and an annular groove is formed in the left side of the control frame; a connecting block is rotatably connected to the side face of the inner wall of the annular groove, a supporting rod is fixedly connected to the left side of the connecting block, a jaw is fixedly connected to the left end of the supporting rod, and a driving button is fixedly connected to the left side of the grab handle. According to the anastomotic stoma reinforcing and leakage preventing device for sleeve gastrectomy, a T-shaped strip of a protection assembly is slidably connected into a moving groove of a grab handle, so that an L-shaped plate can stably cover the outer side of a driving button, a clamping block at the top of the L-shaped strip is embedded into a groove, it is guaranteed that the clamping block is always locked in the groove in cooperation with elastic reset force of a first compression spring, and dual protection is formed; accidental touch on the driving button in an operation is effectively avoided, and the risk of misoperation is reduced.

The invention discloses an adjustable sleeve stomach excision anastomat based on a laparoscope, and relates to the technical field of excision anastomats. The anastomat comprises an anastomat body, a gun barrel is connected to one side of the anastomat body, an execution head is arranged at one end of the gun barrel, a nail bin seat is connected to one side of the execution head, and the execution head is rotationally connected with a nail abutting seat corresponding to the nail bin seat; a supporting seat is arranged in the nail bin seat, a plurality of movable seats are arranged on the upper side of the supporting seat in a sliding fit mode, and a plurality of anastomosis nails are fixedly connected to one sides of the movable seats. The adjustable telescopic assembly is arranged in the supporting seat, the motor can rotate forwards and backwards, the adjustable telescopic assembly drives the multiple movable seats to horizontally stretch out and draw back on the supporting seat, the multiple anastomosis nails can be driven to be close to or far away from one another on the supporting seat, and the anastomosis lengths of the multiple anastomosis nails can be adjusted; the diversified requirements on the sleeve-shaped gastric resection anastomosis length in different operation scenes are met.

The present disclosure relates to a computer system and a method for estimating stomach volume. The computer system includes a memory and a processor that is communicatively coupled to the memory. The processor receives a video of the interior of a stomach and generates a map of the stomach based on the video. The processor also calculates the stomach volume based on the stomach map and detects a suture placed on the stomach during an endoscopic sleeve gastrectomy procedure that causes a change in the stomach's shape, based on the video and using a neural network. The processor further updates the stomach map based on the change in the stomach's shape and updates the calculated stomach volume based on the updated stomach map.

The application discloses a kind of micropeptide molecular markers for early gastric cancer screening, detection reagent and application, the micropeptide molecular markers include the combination of one or more of AC027045.3 gene, OLMLINC gene, ZNF436-AS1 gene or TRHDE-AS1 gene.The application provides a kind of micropeptide molecular markers for early gastric cancer screening, the micropeptide molecular markers include the combination of one or more of AC027045.3 gene, OLMLINC gene, ZNF436-AS1 gene or TRHDE-AS1 gene.By detecting the expression of the new functional biological macromolecule of micropeptide in diagnosis target to assist predicting the progress of tumor, realize the simple screening of gastrectomy before endoscope.
