DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0027] Figures 1 to 7 Shown is an embodiment of the present utility model.
[0028] Example 1:
[0029] A pulmonary artery stenosis interventional surgery training model includes a base plate 1, a transparent box 2 is provided on the upper side of the base plate 1, a heart module 3 is installed in the transparent box 2, the heart module 3 is provided with a right atrium 302 and a right ventricle 303 separated by an atrioventricular valve 301, the heart module 3 is provided with an inferior vena cava 4 connected to the right atrium 302, and the end of the inferior vena cava 4 away from the heart module 3 is placed on the outside of the transparent box 2, the heart module 3 is provided with a pulmonary artery trunk 5 connected to the right ventricle 303, the end of the pulmonary artery trunk 5 away from the right ventricle 303 is connected to the left pulmonary artery 501 and the right pulmonary artery 502, each of the left pulmonary artery 501 and the right pulmonary artery 502 is provided with a plurality of pulmonary artery branches 503, the distal end of the pulmonary artery branch 503 is detachably installed with a lesion tube 504, and the inner walls of the left pulmonary artery 501, the right pulmonary artery 502 and the pulmonary artery branch 503 are provided with at least one pulmonary artery stenosis block 505 protruding from the inner wall. By simulating the structure of the human heart, pulmonary trunk 5, left pulmonary artery 501, right pulmonary artery 502, and pulmonary artery branches 503, the simulation of the entire training model is improved. By setting up diseased tubes 504 and pulmonary artery stenosis modules in different arterial branches, the operator can be trained to control catheters, guidewires, etc. to enter different pulmonary artery branches 503 for interventional surgery during training. By providing a transparent box 2, water mixed with lubricant can be injected into the transparent box 2 to fill the entire transparent box 2, the heart module 3, the pulmonary trunk 5, the left pulmonary artery 501, the right pulmonary artery 502, the pulmonary artery branches 503, and the inferior vena cava 4 with water. On the one hand, this water can be used to simulate human blood and improve the lubricity of operating tools such as catheters or guidewires and the inner wall of the pulmonary artery. On the other hand, after the water is injected, the heart module 3, the pulmonary artery, etc. can be covered with water on both the inner and outer walls, which improves the clarity of observation, making it easier to observe the position and angle of the guidewire or catheter from the side. This helps the operator better adjust their operation method and improve the control feel during operation training. The removable lesion tube 504 allows for replacement of used lesion tubes 504, or for different types of lesion tubes 504 to practice different interventional procedures. The heart module 3, pulmonary trunk 5, left pulmonary artery 501, right pulmonary artery 502, pulmonary artery branches 503, and lesion tube 504 are all made of transparent silicone to simulate the elasticity of human blood vessels and the heart. This transparent silicone material allows for edge observation of the catheter or guidewire's movement.
[0030] The inferior vena cava 4 comprises a first venous segment 401 and a second venous segment 402. A first mounting hole 201 is provided on the side of the transparent box 2, extending from the inside to the outside. A mounting tube 202 is located within the first mounting hole 201. One end of the first venous segment 401 is connected to the right atrium 302 of the heart module 3, and the other end is connected to the mounting tube 202 within the transparent box 2. The second venous segment 402 is located outside the transparent box 2, and one end of the second venous segment 402 is connected to the mounting tube 202 outside the transparent box 2. Dividing the inferior vena cava 4 into the first venous segment 401 and the second venous segment 402 allows for simultaneous installation of the first venous segment 401 and the heart module 3 within the transparent box 2, while the second venous segment 402 is located outside the transparent box 2. This facilitates operator training during interventional procedures, allowing catheters, guidewires, and other devices to be passed through the second venous segment 402 and into the heart module 3. The provision of the first mounting hole 201 and the mounting tube 202 ensures a secure connection between the first and second venous segments 401, 402, while also ensuring a secure seal at the connection.
[0031] The end of the second venous segment 402 away from the mounting tube 202 is connected to the common iliac vein 403. A fixing plate 101 is vertically provided on the upper side of the base plate 1. The fixing plate 101 is provided with second mounting holes 102 running through both sides. A sheath tube 103 is installed in the second mounting hole 102. The end of the common iliac vein 403 away from the second venous segment 402 is connected to the sheath tube 103. By providing the common iliac vein 403, it is possible to simulate a real interventional surgery scene in conjunction with the inferior vena cava 4. During a real pulmonary artery interventional surgery, the sheath tube 103 is generally installed in the thigh to enter the common iliac vein 403. The common iliac vein 403 and the inferior vena cava 4 of the present invention can be used to simulate the length of the catheter required to be inserted into the heart during a real interventional surgery. By setting the fixing plate 101, the connection between the common iliac vein 403 and the sheath 103 can be kept at a certain height from the bottom plate 1, so that the connection between the second venous segment 402 and the common iliac vein 403 can be lower than the common iliac vein 403 and the high end of the fixing plate 101, forming a drop, simulating the real drop of human veins, so that the operator can adapt to the feeling of turning when operating the catheter to move in the inferior vena cava 4.
[0032] The transparent box 2 has an opening on its top, and a drainage hole is provided on its side, near where it meets the inner bottom. A drain valve 203 is installed in the drainage hole. The opening facilitates the filling of water into the transparent box 2. The drainage hole and drain valve 203 prevent leakage by closing the drain valve 203 during water filling. When water needs to be drained, the drain valve 203 is opened and connected to a drain pipe to drain the water from the transparent box 2. This also facilitates drainage when cleaning the transparent box 2, the heart module 3, and the pulmonary artery.
[0033] Example 2:
[0034] Based on Example 1, the bottom of the transparent box 2 is provided with a fixed support frame 204 and a lifting support frame 205 for supporting the heart module 3. The lifting end of the lifting support frame 205 is arranged upward and is connected to the lower side of the connection between the right ventricle 303 and the pulmonary artery trunk 5. By providing the fixed support frame 204, the entire heart module 3 can be fixed within the transparent box 2, at a certain distance from the bottom of the transparent box 2, so that the pulmonary artery trunk 5, the pulmonary artery trunk 5, the left pulmonary artery 501, the right pulmonary artery 502, and the pulmonary artery branches 503 do not adhere to the bottom of the transparent box 2, and the actual positional relationship between them can be simulated by soaking in the water of the transparent box 2. By providing the lifting support frame 205, it can be simulated that when a person breathes, the expansion of the lungs will press against the connection between the right ventricle 303 and the pulmonary artery trunk 5, causing the channel shape of the connection to deform, so that the angle of the connection will change. This allows the operator to more intuitively understand how to operate the catheter to enter the pulmonary artery trunk 5 from different angles during training.
[0035] The lifting support frame 205 includes a fixed section 206 and a movable section 207. The lower end of the fixed section 206 is fixedly connected to the inner bottom of the transparent box 2, and a lifting hole 208 is vertically provided at the upper end. The lower end of the movable section 207 is slid up and down in the lifting hole 208, and the upper end is connected to a support plate 209. The support plate 209 fits the lower side of the connection between the right ventricle 303 and the pulmonary artery trunk 5. A cylindrical airbag 210 is provided in the lifting hole 208. The side wall of the cylindrical airbag 210 is corrugated. The lower end of the cylindrical airbag 210 is connected to the bottom of the lifting hole 208, and the upper end is connected to the lower end of the movable section 207. The cylindrical airbag 210 is connected to the inflation component through the trachea 211. When the inflatable component supplies air to the cylindrical airbag 210, the cylindrical airbag 210 can rise to support the upward movement of the movable section 207, thereby supporting the connection between the right ventricle 303 and the pulmonary artery trunk 5 with the help of the support sheet 209, causing the angle of the connection to change. When the inflatable component discharges the gas in the cylindrical airbag 210 through the trachea 211, the cylindrical airbag 210 shortens with the help of the corrugated outer wall, thereby driving the movable section 207 downward, and supporting the connection between the right ventricle 303 and the pulmonary artery trunk 5 downward with the help of the support sheet 209, causing the angle of the connection to change. In addition, the cylindrical airbag 210 can support the movable section 207 to different heights depending on the amount of air inflated. The inflatable component can use a manual inflatable pump or an electric inflatable pump.
[0036] Example 3:
[0037] Based on the previous embodiment, a receiving socket 506 is provided at the end of the pulmonary artery branch 503 distal to the heart module 3. One end of the lesion tube 504 is inserted into the receiving socket 506, and the other end is provided with a distal closure member 507. The provision of the receiving socket 506 and the lesion tube 504 in conjunction with each other allows for quick installation and removal of the lesion tube 504. During installation, simply insert the end of the lesion tube 504 distal to the distal closure member 507 into the receiving socket 506.
[0038] The interior of the lesion tube 504 is decorated with several lotus-root-shaped brittle sheets 508. These brittle sheets 508 simulate lotus-root-shaped lesions in the pulmonary artery branches 503. During an interventional procedure, a balloon is inserted into the lesion tube 504 via a catheter and a guidewire. The balloon is then inflated to compress the brittle sheets 508, shattering them. The success of the interventional procedure training is determined by the shattering of the brittle sheets 508 within the lesion tube 504.
[0039] The connection between the receiving socket 506 and the pulmonary artery branch 503 is provided with a first abutting plane facing the receiving socket 506, and the end of the lesion tube 504 away from the distal sealing member 507 is provided with a second abutting plane. Figure 4 As shown, the outer wall of the lesion tube 504 at one end of the second abutment plane is adapted to the inner wall of the receiving socket 506, and the inner diameter of the lesion tube 504 is larger than the inner diameter of the pulmonary artery branch 503. With the help of the first abutment plane and the second abutment plane, it is possible to effectively control whether the lesion tube 504 is installed in place. The inner diameter of the receiving socket 506 is in a gradually increasing flared shape, which can make it smoother when inserting the lesion tube 504. By setting the inner diameter of the lesion tube 504 larger than the inner diameter of the pulmonary artery branch 503, it is possible to avoid the appearance of a step towards the pulmonary artery branch 503 at the junction of the first abutment plane and the second abutment plane, which would affect the insertion of the guide wire into the lesion tube 504.
[0040] One end of the distal closure member 507 is provided with a connecting groove 513 having a circular cross-section. A first thread is provided around the wall of the connecting groove 513. A second thread is provided on the outer wall of the lesion tube 504 at the end away from the pulmonary artery branch 503. The first thread and the second thread are threadably connected. The provision of the first and second threads facilitates quick connection between the distal closure member 507 and the lesion tube 504.

More specifically, within the scope of the present disclosure, the drawings, and the claims, various variations and modifications may be made to the components and / or layout of the subject combination arrangement.
