Description

Technical Field

[0001] The invention relates to the technical field of digestive endoscopes, and in particular to a simulation device for digestive endoscopes. Background Art

[0002] Digestive endoscopy plays a key role in the diagnosis and treatment of digestive system diseases. With the continuous development of medical technology, the skill requirements for digestive endoscopy operators are increasing. The traditional teaching model of digestive endoscopy mainly relies on theoretical lectures and watching surgical videos. Trainees lack the opportunity to actually operate, and it is difficult to practice in the real human anatomy and physiological environment. This leads to trainees often facing problems such as unskilled operation and inaccurate lesion identification when they first conduct clinical practice, which increases the pain and medical risks of patients. Therefore, it is of great practical significance to develop a simulation device that can highly simulate the human digestive endoscopy process.

[0003] Although the existing simulation devices are easy to use, there are still some problems. For example, the existing simulation devices are used frequently in students' practical exercises, which will cause bacteria and stains to form in the inner cavity of the simulation device. However, the simulation device is made to imitate the internal structure of the human body, and has certain requirements for the internal sealing, so that it can better simulate the internal organs of the human body, thereby providing students with a more realistic simulation environment. This makes it difficult to open the simulation device and it is difficult to clean the inside. Moreover, opening the simulation device completely for manual processing also allows a large number of external bacteria to enter the inside of the simulation device, which increases the difficulty of cleaning. At the same time, the interior of the simulation device imitates the human organs, resulting in its interior being uneven and prone to cleaning dead corners. Therefore, a simulation device for digestive endoscopy that can automatically and aseptically perform internal cleaning is needed. Summary of the invention

[0041] The first hydraulic cylinder 9 on the first simulation chamber 3 extends upward, while at the same time the first hydraulic cylinder 9 on the second simulation chamber 4 extends downward, so that the multiple groups of first hydraulic cylinders 9 interact with each other to separate the first simulation chamber 3 and the second simulation chamber 4.

[0042] A pinion 14 is fixedly connected to the surface of the rotating rod 12, and a transverse tooth plate 15 is arranged above the pinion 14, which meshes with the pinion 14, and a slide plate 16 is fixedly connected to both sides of the transverse tooth plate 15, and a support rod 18 is fixedly connected to the bottom of the inner cavity of the first empty slot 7 and on both sides of the pinion 14, and the top of the support rod 18 is fixedly connected to a limiting track 17, and the inner cavity of the limiting track 17 is slidably connected to the surface of the slide plate 16, and a mounting plate 19 is fixedly connected to the top of the transverse tooth plate 15, and a first motor 20 is fixedly connected to one side of the top of the mounting plate 19, and a threaded rod 21 is fixedly connected to the output end of the first motor 20, and a vertical plate 22 is fixedly connected to the other side of the top of the mounting plate 19, one end of the threaded rod 21 is rotatably connected to the surface of the vertical plate 22, and a moving block 23 is movably connected to the surface of the threaded rod 21.

[0043] When it is necessary to perform transverse cleaning on the inside of the simulation device, the first motor 20 rotates to drive the threaded rod 21 to rotate, and the rotation of the threaded rod 21 drives the moving block 23 to move. The moving block 23 moves transversely to drive the first scraper 33 and the second scraper 35 to move transversely inside the stomach simulation area 6, thereby performing multi-directional cleaning on the inside of the stomach simulation area 6, with better cleaning effect and wider range, avoiding the occurrence of cleaning dead corners.

[0044] A second hydraulic cylinder 24 is fixedly connected to the top of the moving block 23, a third hydraulic cylinder 25 is fixedly connected to the top of the telescopic end of the second hydraulic cylinder 24, a telescopic end of the third hydraulic cylinder 25 is fixedly connected to a chassis 26, a second motor 27 is fixedly connected to the inner cavity of the chassis 26, a rotating rod 28 is fixedly connected to the output end of the second motor 27, one end of the rotating rod 28 passes through the chassis 26 and extends to the bottom of the chassis 26, a circular plate 29 is fixedly connected to the end of the rotating rod 28 extending to the bottom of the chassis 26, a fixed rod 30 is fixedly connected to the surface of the circular plate 29, a telescopic rod 31 is movably connected to the inside of the fixed rod 30, a spring 32 is fixedly connected between the bottom of the inner cavity of the fixed rod 30 and the bottom of the telescopic rod 31, a first scraper 33 is fixedly connected to one end of the telescopic rod 31, a connecting plate 36 is movably connected between adjacent first scrapers 33, a connecting block 34 is fixedly connected to the surface of the first scraper 33, and a second scraper 35 is fixedly connected to the bottom of the connecting block 34.

[0045] The extension of the first hydraulic cylinder 9 causes the first simulation bin 3 and the second simulation bin 4 to open, and at the same time, the vertical tooth plate 11 rises with the telescopic end of the first hydraulic cylinder 9, and the rising vertical tooth plate 11 drives the large gear 13 to rotate, and the rotation of the large gear 13 drives the rotating rod 12 to rotate, and the rotation of the rotating rod 12 drives the small gear 14 to rotate, and the rotation of the small gear 14 drives the cross-tooth plate 15 to move, and the movement of the cross-tooth plate 15 drives the mounting plate 19 to move, and the movement of the mounting plate 19 drives the moving block 23 to move, and the movement of the moving block 23 drives the first scraper 33 and the second scraper 35 to move above the stomach simulation area 6. At this time, the contact position of the first scraper 33 and the second scraper 35 with the stomach simulation area 6 is controlled by the second hydraulic cylinder 24 and the third hydraulic cylinder 25 to mutually adjust and control the contact position of the first scraper 33 and the second scraper 35 with the stomach simulation area 6, so that the interior of the stomach simulation area 6 can be cleaned and scraped without manual work, and the interior of the stomach simulation area 6 can be effectively cleaned with high intensity to keep the internal environment of the simulation device healthy and improve the service life of the device.

[0046] When the second motor 27 drives the circular plate 29 to rotate and drives the first scraper 33 and the second scraper 35 to rotate, the centrifugal force is greater than the elastic force of the spring 32, so the telescopic rod 31 is thrown out of the inner cavity of the fixed rod 30, so that the diameter of the circle formed by the first scraper 33 becomes larger, and a larger range can be scraped. At the same time, the telescopic rod 31 is extended to increase the pressure inside the stomach simulation area 6, thereby enhancing the scraping effect.

[0047] Working principle: the extension of the first hydraulic cylinder 9 opens the first simulation chamber 3 and the second simulation chamber 4, and at the same time, the vertical tooth plate 11 rises with the telescopic end of the first hydraulic cylinder 9, and the vertical tooth plate 11 rises to drive the large gear 13 to rotate, the rotation of the large gear 13 drives the rotating rod 12 to rotate, the rotation of the rotating rod 12 drives the small gear 14 to rotate, the rotation of the small gear 14 drives the horizontal tooth plate 15 to move, the movement of the horizontal tooth plate 15 drives the installation plate 19 to move, the movement of the installation plate 19 drives the moving block 23 to move, the movement of the moving block 23 drives the first scraper 33 and the second scraper 35 to move to the top of the stomach simulation area 6, and then the second hydraulic cylinder 2 4 and the third hydraulic cylinder 25 mutually adjust and control the contact position of the first scraper 33 and the second scraper 35 with the stomach simulation area 6, so as to clean and scrape the inside of the stomach simulation area 6. When it is necessary to clean the inside of the simulation device horizontally, the first motor 20 rotates to drive the threaded rod 21 to rotate, and the threaded rod 21 rotates to drive the moving block 23 to move. The moving block 23 moves horizontally to drive the first scraper 33 and the second scraper 35 to move horizontally inside the stomach simulation area 6, so as to clean the inside of the stomach simulation area 6 in all directions. Through horizontal and vertical processing, the first scraper 33 and the second scraper 35 can achieve all-round cleaning.
