Description

A vascular interventional surgery teaching simulator Technical Field

[0001] This invention relates to the field of surgical teaching simulator technology, and in particular to a vascular interventional surgery teaching simulator. Background Technology

[0002] Vascular interventional surgery teaching simulators are crucial equipment for training medical students and clinicians in interventional procedures. Existing teaching simulators mostly use ordinary flexible tubing to simulate vascular access, making it difficult to realistically represent the differences in vascular morphology among patients of different ages. They cannot simulate the actual clinical situation of tortuous blood vessels in the elderly and relatively straight blood vessels in younger patients, resulting in a limited training scenario and a significant gap from real clinical cases. This hinders operators from quickly adapting to interventional procedures under different anatomical conditions. Furthermore, when adjusting the existing vascular simulation tubing to a tortuous state or performing instrument pushing operations, the bent position is prone to problems such as tube wall folding and lumen closure. This not only affects the normal passage of guidewires, catheters, and other instruments, disrupting the operator's feel and training process, but also easily damages the simulated blood vessel, reducing the equipment's lifespan and affecting the continuity of teaching and training effectiveness. Therefore, existing vascular interventional surgery teaching simulators still have significant shortcomings in the realism of vascular morphology simulation and the stability of the tortuous structure, failing to meet the needs of efficient, realistic, and stable interventional surgery teaching and training.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By holding the positioning sleeve and pushing the first gear plate outward, the first spring on the inner side is squeezed. At this time, the first gear plate and the second gear plate separate. Rotating the positioning sleeve drives the moving block and the control rod. When the control rod drives the two sets of rings and displacement frames to rotate clockwise, the control rod drives the first gear to rotate clockwise. This drives the meshing second gear and the displacement frame on the upper side of the second gear to rotate counterclockwise along the U-shaped rod. The three sets of displacement frames push the simulation tube, which forms an S-shape at the upper end of the platform shell. At the same time, it pulls the support base to slide on the mounting shell and the control rod, squeezing the second spring. Then, the positioning sleeve is released. The squeezed first spring pushes the first gear plate to mesh with the second gear plate, positioning the control rod and the three sets of rotating displacement frames to simulate the vascular morphology of an older person.

[0015] 2. Using a hexagonal tool, insert it into the nut corresponding to the movable opening position, control the nut and the threaded rod to rotate in both directions, drive the threaded rack to slide on the slide rail, the sliding rack drives the meshing half gear to rotate in both directions, and the half gear drives the displacement frame to push the simulation tube to bend, so as to adjust the simulation tube individually and obtain the desired degree of bending.

[0016] 3. To prevent the simulation tube from folding when bent, the one-way airbag is pressed to inflate the micro-inflatable tube. The micro-inflatable tube is spiral-shaped, which effectively prevents the simulation tube from folding and collapsing when bent, ensuring unobstructed lumen. The soft and hard state of the blood vessels after inflation better simulates the difference between the blood vessels of the elderly and young people. The gas in the micro-inflatable tube can be released by opening the cap of the threaded connection. Attached Figure Description

An anti-bend component 6 is disposed inside the control component 4 and the adjustment component 5. The control component 4 includes a mounting shell 41 fixedly installed on the upper end of the fixing plate 1. Two sets of partition plates 42 are fixedly disposed inside the mounting shell 41. A platform shell 43 is fixedly installed on the upper end of the mounting shell 41 corresponding to the two sets of partition plates 42. Three sets of movable openings 44 are opened inside the mounting shell 41 and the platform shell 43. A control rod 45 is movably disposed inside the two sets of partition plates 42. The front end of the control rod 45 is fixed... A movable block 46 is fixedly provided, and a positioning sleeve 47 is slidably provided on the outer side of the movable block 46. A first gear 48 is fixedly provided at the rear end of the positioning sleeve 47. A first spring 49 is sleeved between the movable block 46 and the first gear 48 on the outer side of the control rod 45. A second gear 410 is fixedly provided at the front end of the mounting shell 41 corresponding to the position of the first gear 48. A first gear 411 is fixedly provided on the outer side of the control rod 45. A U-shaped rod 412 is fixedly provided on the upper inner wall of the platform shell 43. A second gear 413 is rotatably provided on the outer side of the U-shaped rod 412. A ring 414 is fixedly provided on the outer side of the control rod 45 on both the front and rear sides of the first gear 411. A support seat 415 is provided on the inner side of the mounting shell 41 near the front and rear inner walls. A second spring 416 is sleeved between the front support seat 415 and the partition plate 42 on the outer side of the control rod 45.

[0029] The control lever 45 passes through two sets of partition plates 42 and the front support base 415 and the front position of the mounting shell 41. The positioning sleeve 47 is movably connected to the control lever 45. The first gear plate 48 and the second gear plate 410 are meshed. The first gear plate 48, the second gear plate 410 and the control lever 45 are movably connected. The first gear 411 and the second gear 413 are meshed.

[0030] By holding the positioning sleeve 47 and pushing the first gear 48 outward, the first spring 49 on the inner side is squeezed. At this time, the first gear 48 and the second gear 410 are separated. Rotating the positioning sleeve 47 drives the movable block 46 and the control rod 45. When the control rod 45 drives the two sets of rings 414 and the displacement frame 54 to rotate clockwise, the control rod 45 drives the first gear 411 to rotate clockwise, driving the meshing second gear 413 and the displacement frame 54 on the upper side of the second gear 413 to rotate counterclockwise along the U-shaped rod 412. The three sets of displacement frames 54 push the simulation tube 61, which forms an S-shape at the upper end of the platform shell 43. At the same time, the support seat 415 is pulled to slide on the mounting shell 41 and the control rod 45, squeezing the second spring 416. Then, the positioning sleeve 47 is released. The squeezed first spring 49 pushes the first gear 48 and the second gear 410 to mesh, positioning the control rod 45 and the rotating three sets of displacement frames 54 to simulate the morphology of blood vessels in older people.

[0031] The adjusting assembly 5 includes three sets of slide rails 51 fixedly mounted on the upper side of the second gear 413 and two sets of rings 414. Two sets of fixing blocks 52 are fixedly mounted on the upper end of the slide rails 51. Half gears 53 are movably mounted on the inner side of the two sets of fixing blocks 52. A displacement frame 54 is fixedly mounted on the upper side of the half gears 53. A rack 55 is slidably mounted on the inner side of the slide rails 51. A threaded rod 56 is movably mounted on the inner side of the slide rails 51 and the rack 55. A nut 57 is fixedly mounted on one end of the threaded rod 56.

[0032] The slide rail 51 corresponds to the position of the movable opening 44. The half gear 53 and the rack 55 are meshed. The displacement frame 54 is adapted to the movable opening 44. The rack 55 and the threaded rod 56 are threadedly connected.

[0033] Using a hexagonal tool, insert the nut 57 corresponding to the position of the movable opening 44, control the nut 57 and the threaded rod 56 to rotate in both directions, drive the threaded rack 55 to slide on the slide rail 51, the sliding rack 55 drives the meshing half gear 53 to rotate in both directions, and the half gear 53 drives the displacement frame 54 to push the simulation tube 61 to bend, so as to adjust the simulation tube 61 individually and obtain the desired degree of bending.

[0034] The anti-bend assembly 6 includes a simulated tube 61 fixedly installed in two sets of support seats 415. Limiting pieces 62 are provided on both the front and rear sides of the simulated tube 61. A connecting tube 63 is fixedly installed on the rear side of the simulated tube 61. A conduit 64 is fixedly installed on the front side of the simulated tube 61. A miniature inflation tube 65 is fixedly installed on the outside of the simulated tube 61. A connector 66 is fixedly installed at one end of the front side of the miniature inflation tube 65. An airbag tube 67 is fixedly installed on one side of the connector 66. A one-way airbag 68 is fixedly installed at one end of the airbag tube 67. A deflation tube 69 is fixedly installed on the upper side of the connector 66. A cap 610 is threaded onto one end of the deflation tube 69.

[0035] The simulation tube 61 passes through the inner side of the three sets of displacement frames 54. The front and rear sides of the simulation tube 61 are restricted on the two sets of support seats 415. The connecting tube 63 is fixedly set on the inner side of the heart simulation bag 3. The micro inflation tube 65 is embedded in the outer skin of the simulation tube 61. The micro inflation tube 65 is spirally wound on the simulation tube 61. The air bag tube 67, the deflation tube 69 and the micro inflation tube 65 are connected to each other.

[0036] To prevent the simulation tube 61 from folding when bent, the one-way airbag 68 is pressed, and the airbag tube 67 inflates the micro-inflatable tube 65. The micro-inflatable tube 65 is spiral-shaped, which effectively prevents the simulation tube 61 from folding and collapsing when bent, ensuring the lumen is unobstructed. After inflation, the softness and hardness of the blood vessels better simulate the difference between the blood vessels of the elderly and young people. The gas in the micro-inflatable tube 65 can be released by opening the threaded cap 610.

[0037] Working principle: In use, by holding the positioning sleeve 47 and pushing the first gear 48 outward, the first spring 49 on the inner side is compressed. At this time, the first gear 48 separates from the second gear 410. Rotating the positioning sleeve 47 drives the movable block 46 and the control rod 45. When the control rod 45 drives the two sets of rings 414 and the displacement frame 54 to rotate clockwise, the control rod 45 drives the first gear 411 to rotate clockwise, driving the meshing second gear 413 and the displacement frame 54 on the upper side of the second gear 413 to rotate counterclockwise along the U-shaped rod 412. The three sets of displacement frames 54 push the simulation tube 61, forming an S-shape at the upper end of the platform shell 43. At the same time, the support base 415 is pulled to slide on the mounting shell 41 and the control rod 45, compressing the second spring 416. Then, the positioning sleeve 47 is released, and the compressed first spring 49 pushes the first gear 48 to mesh with the second gear 410, positioning the control rod 45 and the rotating three sets of displacement frames 54, simulating The vascular morphology of older individuals is analyzed. Additionally, a hexagonal tool is inserted into the nut 57 at the corresponding position of the movable opening 44. The nut 57 and threaded rod 56 are rotated in both directions, driving the threaded rack 55 to slide on the slide rail 51. The sliding rack 55 drives the meshing half-gear 53 to rotate in both directions, which in turn drives the displacement frame 54 to bend the simulation tube 61, allowing for individual adjustment of the simulation tube 61 to achieve the desired degree of bending. Furthermore, to prevent the simulation tube 61 from folding during bending, the one-way airbag 68 is pressed, causing the airbag tube 67 to inflate the micro-inflatable tube 65. The micro-inflatable tube 65 is spiral-shaped, effectively preventing the simulation tube 61 from folding and collapsing during bending, ensuring unobstructed lumen. The inflated blood vessel firmness better simulates the differences between the blood vessels of the elderly and young people. The gas in the micro-inflatable tube 65 can be released by opening the threaded cap 610.

Their working principle is already known technology, and the appropriate model is selected according to actual use, so it will not be explained in detail.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
