Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of medical teaching aids, specifically to a cardiovascular interventional therapy simulation training device. Background Technology
[0002] Interventional therapy is an emerging treatment method that falls between surgical and medical treatments, including endovascular and non-vascular interventional therapies. Simply put, interventional therapy involves creating tiny channels (a few millimeters in diameter) in blood vessels or skin, or through existing bodily channels, to treat the lesion locally under the guidance of imaging equipment (angiography machine, fluoroscopy machine, CT, MRI, ultrasound). It is a minimally invasive treatment method often used to treat cardiovascular patients.
[0003] Due to the special nature of cardiovascular treatment, young doctors often learn through an "apprenticeship" training model, usually taught by experienced surgeons. They learn how to operate catheters, guidewires, balloons, stents, and other instruments during surgery. This model is inefficient and very unsafe, and the cycle from learning from experienced doctors to performing clinical procedures on their own is very long. Utility Model Content
[0004] To address the aforementioned problems, this invention proposes a cardiovascular interventional therapy simulation training device.
[0005] The purpose of this utility model is achieved through the following technical solution: a cardiovascular interventional therapy simulation training device, including a base, a simulation box on the base, the simulation box including a box body and a sealing cover, a first filling rubber plug on the sealing cover, a cardiovascular model horizontally installed inside the box body, an intervention box sealed to both ends of the cardiovascular model, and a second filling rubber plug and an intervention point rubber plug on the intervention box.
[0006] In a preferred embodiment, the two ends of the box body are provided with through holes, the two ends of the cardiovascular model are inserted into the through holes, the end of the cardiovascular model is provided with a limiting rubber ring, the limiting rubber ring is sealed and attached to the inner wall of the intervention box, and the intervention box is detachably installed at the end of the box body.
[0007] In a preferred embodiment, the bottom plate of the box body is provided with a plurality of insertion holes, and a limiting post is movably inserted into the insertion holes. The limiting post is used to fix the shape of the cardiovascular model, and the top of the limiting post contacts the inner wall of the sealing cover.
[0008] In a preferred embodiment, the box body is provided with mounting plates on both sides, the mounting plates are provided with mounting holes, and the base is provided with corresponding insertion rods, the mounting holes being fitted onto the insertion rods.
[0009] In a preferred embodiment, the sealing cap has a transparent window in the middle.
[0010] In a preferred embodiment, the interior of the box is filled with a transparent solution by puncturing the first filling rubber stopper, and the interior of the cardiovascular model is filled with a color developing solution by puncturing the second filling rubber stopper.
[0011] This utility model has the following advantages compared with the prior art:
[0012] 1. This utility model involves inserting an interventional needle into the cardiovascular model through an interventional point plug, allowing for simulation training. The cardiovascular model can be replaced after separating the sealing cap from the box. During installation, the cardiovascular model is first passed through the box surface, then inserted into the interventional box. This process causes the limiting rubber ring to deform under pressure, returning to its original position after entering the box. The interventional box is then installed at both ends, allowing the cardiovascular model to simulate the actual human cardiovascular structure. This effectively shortens the time trainees spend learning the procedure outside the operating room. Furthermore, by changing to different cardiovascular models, trainees can easily conduct simulated surgical training based on corresponding lesion types, significantly reducing the learning curve and improving their proficiency and skills in operating related instruments during the surgical procedure.
[0013] 2. This utility model uses a first filling rubber stopper to inject a transparent solution into the box, and a second filling rubber stopper to inject a color-developing solution into the cardiovascular model. If the cardiovascular model breaks due to operational errors during training, the color-developing solution inside the cardiovascular model will flow out and mix with the transparent solution inside the box, thus clearly showing the damage point of the cardiovascular model, so that the trainee can summarize the experience of failure.

[0018] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to exemplarily illustrate the principles of this utility model, but should not be used to limit the scope of this utility model. That is, this utility model is not limited to the described preferred embodiments, and the scope of this utility model is defined by the claims.
[0019] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance; those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0020] Example 1
[0021] See Figure 1 , Figure 2 This embodiment provides a cardiovascular interventional therapy simulation training device, including a base 1, a simulation box 2 on the base 1, the simulation box 2 including a box body 23 and a sealing cover 24, the sealing cover 24 being sealed to the opening of the box body 23, the sealing cover 24 having a first filling port, the first filling port being sealed by a first filling rubber stopper 27, the first filling rubber stopper 27 being interference fit with the first filling port, when the sealed first filling port needs to be used, the first filling rubber stopper 27 can be directly punctured, improving the convenience of use; a cardiovascular model 21 is horizontally installed inside the box body 23, the cardiovascular model The two ends of the type 21 are sealed with intervention boxes 22. The top surface of the intervention box 22 is provided with a second filling port, which is sealed by a second filling rubber plug 3. The second filling rubber plug 3 and the second filling port are press-fitted. When the closed second filling port needs to be used, the second filling rubber plug 3 can be punctured directly, which improves the convenience of use. The outer side of the intervention box 22 is provided with an intervention port, which is sealed by an intervention point rubber plug 31. The intervention point rubber plug 31 and the intervention port are press-fitted. When the closed intervention port needs to be used, the intervention point rubber plug 31 can be punctured directly, which improves the convenience of use.
[0022] In this embodiment, the two ends of the box body 23 are provided with through holes (not shown in the figure), and the two ends of the cardiovascular model 21 are inserted into the through holes. The cardiovascular model 21 is press-fitted with the through holes to achieve a tight fit between the surface of the cardiovascular model 21 and the inner wall of the through holes. The end of the cardiovascular model 21 is provided with a limiting rubber ring 32, which is sealed and fitted to the inner wall of the intervention box 22. The intervention box 22 is detachably installed at the end of the box body 23.
[0023] By inserting the interventional needle into the cardiovascular model 21 through the interventional plug 31, simulation training can be conducted. After separating the sealing cap 24 from the box 23, the cardiovascular model 21 can be replaced. During installation, the cardiovascular model 21 is first passed through the surface of the box 23, and then inserted into the interventional box 22. During this process, the limiting rubber ring 32 is squeezed and deformed, and after the limiting rubber ring 32 enters the interventional box 22, it returns to its original position to achieve limitation. Then, the interventional box 22 is installed at both ends of the box 23, thus installing the cardiovascular model 21 inside the box 23. This allows the cardiovascular model 21 to simulate the actual human cardiovascular structure, effectively shortening the training period for trainees outside the operating room. Furthermore, by changing different cardiovascular models 21, trainees can easily conduct simulated surgical training according to the corresponding lesion, greatly shortening the trainees' surgical learning curve and improving their proficiency and skills in operating related instruments during the surgical procedure.
[0024] See Figure 2 In this embodiment, the bottom plate of the box 23 is provided with several insertion holes 25. The insertion holes 25 are blind holes. A limiting post 26 is movably inserted into the insertion hole 25. The limiting post 26 is used to fix the shape of the cardiovascular model 21. The top of the limiting post 26 contacts the inner wall of the sealing cover 24.
[0025] The cardiovascular model 21 uses a thin-walled tubular structure made of silicone to simulate the structure of human blood vessels. It is inserted into the array of sockets 25 through limiting posts 26. The side of the limiting posts 26 is closely attached to the surface of the cardiovascular model 21. Multiple limiting posts 26 form the installation path of the cardiovascular model 21. The limiting posts 26 limit the cardiovascular model 21 and adjust the curvature of the cardiovascular model 21 to adapt to the differences in the cardiovascular model 21 caused by different human bodies, making it more practical.
[0026] See Figure 1 , Figure 2 The box body 23 has mounting plates 28 on both sides, mounting holes 29 on the mounting plates 28, and corresponding insertion rods 11 on the base 1. The mounting holes 29 are fitted onto the insertion rods 11.
[0027] The simulation box 2 and the base 1 are installed by fitting the mounting hole 29 onto the surface of the insertion rod 11, which makes the device stable during training and more convenient to install and remove.
[0028] In this embodiment, a transparent window is provided in the middle of the sealing cap 24, and the first filling rubber plug 27 is located on the transparent window. The transparent window allows the trainee to more intuitively observe the state of the cardiovascular model 21 during the training process. In this embodiment, the first filling rubber plug 27, the second filling rubber plug 3, and the intervention point rubber plug 31 are medical rubber plugs.
[0029] The interior of the box 23 is filled with a transparent solution by piercing the first filling rubber stopper 27, and the interior of the cardiovascular model 21 is filled with a color developing solution by piercing the second filling rubber stopper 3.
[0030] This invention uses a first filling stopper to inject a transparent solution into the box, and a second filling stopper to inject a color-developing solution into the cardiovascular model. If the cardiovascular model ruptures due to operational errors during training, the color-developing solution inside the cardiovascular model flows out and mixes with the transparent solution inside the box, thus clearly showing the damage point of the cardiovascular model, allowing trainees to summarize their failure experience.
[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
