Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical training simulation, in particular to a high-simulation upper gastrointestinal endoscope training simulator based on clinical data. BACKGROUND

[0002] Gastrointestinal endoscopy is one of the important steps for evaluating and diagnosing the health of the digestive system, and in endoscopy, the above-mentioned gastrointestinal cancer and related lesions that may be cancerous can be found. In the current medical diagnosis and analysis of upper gastrointestinal diseases, the internal images of the body are usually obtained through tools such as endoscopes, and then the medical staff judges the image belonging to which part of the digestive tract and whether there is a lesion, and which kind of lesion.

[0003] Simulation training can avoid direct contact with patients, reduce the risk of operation errors, and has high safety. After simulation training, medical personnel can effectively reduce the error rate in the clinical practice stage. To solve the problems of insufficient simulation of existing endoscope training devices, inability to provide real tactile feedback, and difficulty in meeting the training needs of endoscopic resection operations, a high-simulation upper gastrointestinal endoscope training simulator based on clinical data is proposed. Through high-precision three-dimensional reconstruction technology and 3D printing technology based on clinical data, combined with real imaging data, a highly simulated upper gastrointestinal endoscope training simulator is constructed to provide an efficient training tool that can truly restore the endoscopic operating environment and support endoscopic resection, thereby improving the operating skills of endoscopists, reducing medical risks, and promoting the standardization and normalization of endoscopic technology training to meet the training needs of medical personnel at different levels. SUMMARY

[0004] The present application provides a high-simulation upper gastrointestinal endoscope training simulator based on clinical data, which solves the problems of insufficient simulation of existing endoscope training devices, inability to provide real tactile feedback, and difficulty in meeting the training needs of endoscopic resection operations. It can provide an efficient training tool that can truly restore the endoscopic operating environment and support endoscopic resection, thereby improving the operating skills of endoscopists, reducing medical risks, and promoting the standardization and normalization of endoscopic technology training.

[0005] The solution to the above technical problem is as follows: a high-simulation upper gastrointestinal endoscope training simulator based on clinical data, comprising an external frame, a fixed model, an upper gastrointestinal model, a simulated oral entrance, and an external power supply. The external frame comprises a head external frame and a thoraco-abdominal external frame, and the head external frame and the thoraco-abdominal external frame are integrally manufactured.

[0006] The fixed model comprises a lung reconstruction model, a spinal column reconstruction model, a diaphragm reconstruction model, a liver reconstruction model, and a gallbladder reconstruction model, and the lung reconstruction model, the spinal column reconstruction model, the diaphragm reconstruction model, the liver reconstruction model, and the gallbladder reconstruction model are placed in the thoraco-abdominal external frame.

[0007] The upper digestive tract model includes an esophagus silicone model, a stomach silicone model, a duodenum silicone model, and a pancreas and pancreatic duct silicone model, and the simulated oral entrance is connected to the esophagus silicone model;

[0008] A conductive soft rubber layer is provided in the upper digestive tract model, and a power connection line is provided on the fixed model, the upper digestive tract model and the conductive soft rubber layer. The power connection line is connected to an external power source.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the manufacturing method of the training simulator comprises the following steps:

[0011] S1: Data acquisition: A clinical gastric tube is placed into the patient's stomach cavity, and the upper digestive tract is filled with gas. CT scans are combined to obtain real image data, and three-dimensional reconstruction is performed to generate a model.

[0012] S2: Model production: A simulation model was made using reverse mold opening technology to simulate the real upper digestive tract structure; conductive rubber and oil layer coating were used to simulate the body fluid environment;

[0013] S3: Optimize accessories: Use 3D printing technology to create relevant anatomical models of the spine, liver, and diaphragm, and combine these accessories with the upper gastrointestinal tract model to form a complete training scenario;

[0014] S4: Housing assembly: Construct the device that simulates the human upper body and oral cavity, integrate the upper digestive tract model and accessories, and configure the power supply to meet functional requirements.

[0015] Furthermore, the lung reconstruction model, spine reconstruction model, diaphragm reconstruction model, liver reconstruction model, and gallbladder reconstruction model are designed based on real human CT scan data and constructed through 3D printing technology. They can simulate the restraint effects of the spine, muscles, and ligaments to ensure the realism of endoscopic operations.

[0016] Furthermore, the simulated oral entrance is designed to be consistent with a real endoscope operating interface, ensuring that the endoscope can be smoothly inserted and inspection and treatment operations can be performed.

[0017] Furthermore, the esophagus silicone model, stomach silicone model, duodenum silicone model, pancreas and pancreatic duct silicone model can be installed in the external frame of the chest and abdomen using pressure-sensitive adhesive and magnetic / snap-on structure.

[0018] Furthermore, the conductive soft rubber layer is filled with soft rubber material into specific parts of the model through TPU perfusion technology to simulate the elasticity and toughness of tissues such as the stomach wall and intestinal wall. At the same time, metal conductive material is added to make it have conductive properties, which can further complete further training operations such as electrocautery.

[0019] Furthermore, the external power supply supplies power to each model and the conductive soft rubber layer, thereby realizing the conductive function when the endoscope operates the instrument.

[0020] The beneficial effects of the present invention are as follows: the present invention provides a highly simulated upper gastrointestinal endoscopy training simulator based on clinical data, which has the following advantages:

[0021] 1. The model is 3D reconstructed based on real CT data, with an anatomical structure error of less than 1 mm. It can realistically reproduce the upper gastrointestinal tract and adjacent structures (such as the esophagus, stomach, and duodenum), improving the authenticity and effectiveness of endoscopic training.

[0022] 2. Models based on real CT data can be used for preoperative simulation, reducing surgical risks and improving the intelligent medical experience.

[0023] 3. The conductive soft rubber ensures that it can simulate the inflation and suction during endoscopic operation, and can be connected to instruments such as endoscopic electrosurgery to achieve cutting operations.

[0024] 4. It can integrate endoscopic surgical treatment training for gastroscopy (esophageal and gastric lesions) and duodenoscope (pancreaticobiliary system lesions);

[0025] 5. Such a training simulator can provide a highly simulated endoscopic operation environment, using high-precision 3D modeling and printing, and three-dimensional reconstruction based on inflation CT image data. Through 3D printing technology, high-precision model manufacturing is achieved. It can accurately restore the anatomical structure of the upper gastrointestinal tract, provide realistic visual and tactile feedback, support the simulation of multiple lesions, meet the training needs of physicians at different levels, significantly improve endoscopic operation skills, reduce medical risks, and has important clinical application value.
