Description

Technical Field

[0001] The present invention relates to the field of interventional surgical instrument teaching, and in particular to a full-range monitoring aortic balloon occlusion training simulation system. Background Art

[0002] Aortic resuscitative endovascular balloon occlusion is a minimally invasive interventional hemostasis technology. A balloon catheter is inserted into the aorta through the femoral artery. The area of the aorta where the balloon needs to be inserted is determined based on the bleeding site. After the balloon is inflated to block blood flow, bleeding below the occlusion point is quickly and efficiently controlled. It is suitable for emergency treatment of patients with massive bleeding, such as hemorrhage from non-compressible trunk, groin, and axillary junction trauma. This emergency interventional treatment technology requires rescuers to be proficient in technical operation essentials and to implement treatment in a timely and accurate manner. However, there are limited training opportunities for rescuers' skills training in real clinical environments.

[0003] To this end, there is a training model for aortic balloon occlusion, which simulates an artery, punctures the artery and places a balloon inside the artery. The balloon filling level is detected by a pressure sensor to detect whether the balloon has completed the occlusion task.

[0004] When the balloon initially enters the artery and is not inflated, there is a gap between the balloon and the artery. The distance from the outer wall of the balloon to the artery is not always the same. Therefore, during the balloon filling process, the time it takes for the outer wall at different positions to reach the inner wall of the artery is different. The outer wall at the bottom of the balloon may reach the inner wall of the artery the earliest and exert pressure on the inner wall of the artery. At this time, the other parts of the outer wall of the balloon have not reached the inner wall of the artery. The pressure value detected outside the bottom of the artery only means that the bottom of the balloon is pressing against the bottom of the artery, and the balloon may not completely block the inside of the artery.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] like Figure 1 As shown, the present invention provides a full-range monitoring aortic balloon occlusion training simulation system, which includes a humanoid shell 1, a filling detection device 2 and an occlusion test structure 3.

[0046] Among them, the humanoid shell 1 is provided with a bracket 4, an artery simulation structure 5 is installed on the bracket 4, at least two pressure-covering structures 6 are provided on the artery simulation structure 5, a limiting cavity 7 is formed between the pressure-covering structure 6 and the artery simulation structure 5, the artery simulation structure 5 is fixed in the limiting cavity 7, and a balloon inlet 8 is provided on the artery simulation structure 5.

[0047] The filling detection device 2 includes a first pod 21 and a second pod 22. A detection section 9 is provided between the pressure cover structure 6. Several first pods 21 and second pods 22 are distributed in sequence in the detection section 9 and are all mounted outside the artery simulation structure 5. Detection axis frames 23 are installed at equal intervals on the inner circumference of the first pod 21, and the ends of the detection axis frames 23 are in contact with the artery simulation structure 5.

[0048] The blocking test structure 3 is arranged at the end of the artery simulation structure 5. A ventilation channel 10 is formed in the artery simulation structure 5. A balloon 11 is built into the ventilation channel 10. The blocking test structure 3 quantitatively delivers gas to the ventilation channel 10 from one end and detects the gas circulation from the other end.

[0049] Among them, Figure 3 As shown, a plurality of first pressure sensors 24 are provided on the inner circumference of the second cylinder 22 to detect that the end of the shaft frame 23 expands outward following the expansion of the outer wall of the artery simulation structure 5 .

[0050] In an embodiment of the present invention, a detection section 9 is set between the pressure cover structures 6, a first cylinder cabin 21 and a second cylinder cabin 22 are set in the detection section 9, and a detection axis frame 23 is set on the inner circumference of the first cylinder cabin 21. The detection axis frame 23 is used to detect the expansion and contraction of the outer wall of the artery simulation structure 5. The detection axis frame 23 at each position can be used to determine the specific position where the balloon 11 reaches for filling and the filling state. In addition, a blocking test structure 3 is set at the end of the artery simulation structure 5, which can determine whether the balloon 11 completely blocks the artery simulation structure 5. The ideal filling state and overfilling state of the balloon 11 and the blocking continuity of the corresponding state can be obtained by analyzing the filling state and blocking state at different positions of the artery simulation structure 5, so as to facilitate adjusting the filling degree of the balloon 11 according to the blocking continuity result to achieve the best blocking effect.

[0051] Among them, the humanoid shell 1 simulates the upper body and part of the lower body of a person, and is mainly used to place the artery simulation structure 5. The pressure cover structure 6 and the bracket 4 play a role in limiting the artery simulation structure 5. In addition, the second cylinder cabin 22 also plays a role in fixing part of the artery simulation structure 5.

[0052] In the present invention, the filling detection device 2, on the one hand, realizes real-time monitoring of the outer wall pressure changes of the artery simulation structure 5 at the corresponding position through the internal design of the second cylinder cabin 22, and on the other hand, realizes real-time monitoring of the expansion and contraction movements of the artery simulation structure 5 at the corresponding position through the internal design of the first cylinder cabin 21. This section of the test structure 3 detects whether the balloon 11 is blocked during the filling process, so as to judge the ideal filling state, overfilling state and pressure values and expansion and contraction movement changes of the artery simulation structure 5 on the side corresponding to different states during the filling process of the balloon 11, so as to better judge the result of the filling of the balloon 11.

[0053] The filling detection device 2 can detect the pressure change and expansion and contraction movement of the outer wall of the artery simulation structure 5. The filling detection device 2 of the present invention adopts the following preferred embodiments, such as Figure 4 、 Figure 5 and Figure 8 As shown, the filling detection device 2 includes a mounting groove 25 arranged in the first pod 21, a connecting shaft 26 arranged at the end of the detection axis frame 23, and a side groove 27 arranged in the mounting groove 25. The first pod 21 and the second pod 22 are both fixedly mounted on the bracket 4. The detection axis frame 23 is arc-shaped. The detection axis frame 23 is rotatably arranged in the mounting groove 25 through the connecting shaft 26. The end of the connecting shaft 26 is rotatably arranged in the side groove 27. A torsion spring 28 is arranged in the side groove 27. One end of the torsion spring 28 is connected to the connecting shaft 26, and the other end is connected to the bottom of the side groove 27.

[0054] When the outer wall of the artery simulation structure 5 is extended and retracted, the detection axis frame 23 at the corresponding position will support and drive the detection axis frame 23 to move outward, driving the detection axis frame 23 to rotate. In the actual application of the present invention, the torsion spring 28 is in a natural state corresponding to the state in which the artery simulation structure 5 is not extended and retracted. At this time, the end of the detection axis frame 23 is only in contact with the outer wall of the artery simulation structure 5, and no force is generated. Therefore, when the corresponding position of the artery simulation structure 5 is extended outward under the action of the balloon 11, the detection axis frame 23 is driven to rotate outward. In this case, the end of the detection axis frame 23 is also subjected to a force of the torsion spring 28 in the opposite direction. Later, during the contraction of the artery simulation structure 5, under the action of the torsion spring 28, the detection axis frame 23 can also always maintain contact with the outer wall of the artery simulation structure 5.

[0055] The rotation of the detection axis frame 23 can reflect whether the corresponding position of the artery simulation structure 5 is in extension or retraction. In order to detect the movement of the corresponding detection axis frame 23, the present invention also makes the following design, such as Figure 6 and Figure 7 As shown, an arc plate 29 is provided outside the connecting shaft 26, and the outer end surface of the arc plate 29 is connected to the outer wall of the connecting shaft 26 through an inclined surface 210. A connecting groove seat 211 is provided in the mounting groove 25, and a matching arc groove 212 is provided on the end surface of the connecting groove seat 211 close to the arc plate 29, and the arc plate 29 is slidably set in the matching arc groove 212.

[0056] A through groove 213 is provided in the connecting groove seat 211, and one end of the through groove 213 is connected to an extrusion airbag 214, which is provided in the fitting arc groove 212. A connecting airbag 215 is provided at the other end of the through groove 213, and a second pressure sensor 216 is provided in the connecting groove seat 211. The connecting airbag 215 is provided in the connecting groove seat 211, and the second pressure sensor 216 is in contact with the connecting airbag 215. The connecting airbag 215, the extrusion airbag 214 and the through groove 213 are connected to each other.

[0057] In the above embodiment, the detection shaft frame 23 rotates, driving the connecting shaft 26 to rotate, and the arc plate 29 to rotate. During the rotation of the arc plate 29, the inclined surface 210 and the arc plate 29 gradually squeeze the extrusion airbag 214, and squeeze the gas in the extrusion airbag 214 into the connecting airbag 215 through the through groove 213. The air pressure in the connecting airbag 215 increases, so that the overall volume of the connecting airbag 215 increases. The second pressure sensor 216 contacts the connecting airbag 215. When the volume of the connecting airbag 215 continues to increase, the pressure value detected by the second pressure sensor 216 increases. Therefore, the change of the detection shaft frame 23 can be judged by the change of the pressure value.

[0058] The detection axis frames 23 are arranged at equal intervals in the first cylinder cabin 21. The more detection axis frames 23 there are, the more contact ends between the detection axis frames 23 and the artery simulation structure 5, and the detected expansion and contraction changes at different positions of the outer wall of the artery simulation structure 5 are more accurate. Considering that adjacent detection axis frames 23 may interfere with each other during rotation, the present invention also has the following design: the upper end surface of the end of the detection axis frame 23 is provided with a placement groove 217, and the placement groove 217 is for the adjacent detection axis frames 23 to be placed near one end of the connecting shaft 26.

[0059] When the detection shaft frame 23 is retracted into the installation groove 25, the connection groove seat 211 and other structures on one side of the connection shaft 26 will not cause a stop to the detection shaft frame 23, and the connection groove seat 211, the connection shaft 26 and other structures will gradually correspond to the placement groove 217.

[0060] In addition, the first pressure sensor 24 in the present invention is attached to the outer wall of the artery simulation structure 5, and can monitor the pressure changes at different positions of the outer wall of the artery simulation structure 5 in real time, and can also determine at the first time which side wall the balloon 11 is closest to in the artery simulation structure 5 to be filled. This can illustrate that the pressure change of a certain part of the side wall in the artery simulation structure 5 cannot directly determine whether the balloon 11 is completely blocked.

[0061] In the present invention, the steps for making the artery simulation structure 5 are as follows: using MR images of a 24-year-old healthy male youth, extracting 3D data from the arterial arch to the femoral artery and some branching structures, measuring the diameter at every 5CM interval, and using materials with physical properties similar to those of arterial blood vessels to make simulated arterial blood vessels.

[0062] Among them, the artery simulation structure 5 includes an abdominal artery 51, an iliac artery 52 and a branch artery 53 connected to the abdominal artery 51 and the iliac artery 52. The iliac artery 52 is connected to the end of the abdominal artery 51, and the balloon inlet 8 is set on the branch artery 53.

[0063] Among them, the balloon inlet 8 is also the puncture point in the actual application process. Some branch arteries 53 are distributed on the abdominal artery 51 and are scattered. In order to avoid compressing the corresponding branch arteries 53, no compression and fixation are performed at the corresponding branch artery 53 position. Correspondingly, the balloon 8 filling position is far away from the branch artery 53, and the first cylinder cabin 21 and the second cylinder cabin 22 are not set at the corresponding position.

[0064] In order to detect the blocking condition of the balloon 11, the present invention also provides a blocking test structure 3, which includes an air pump 31 arranged at the end of the abdominal artery 51 and a gas detector 32 arranged on the branch artery 53; except for the branch artery 53 on which the balloon inlet 8 is installed, the ends of other branch arteries 53 are all provided with sealing plugs 12.

[0065] Gas is delivered to the abdominal artery 51, the iliac artery 52, and the branch artery 53 through the vacuum pump 31. The gas simulates blood. A gas detector 32 is set at the branch artery 53 to detect the gas circulation. The branch arteries 53 at other positions are sealed by the sealing plug 12. Assuming that the balloon 11 is in an ideal filling state, at this time, the gas detector 32 should just be unable to detect the delivered gas. When the balloon 11 is still being filled, the artery simulation structure 5 will be in an overfilled state.

[0066] In the present invention, the first pressure sensor 24 close to the balloon inlet 8 is 20 cm away from the balloon inlet 8, that is, the position 20 cm away from the puncture point can be used as the starting position for filling the balloon 11.

[0067] The length of the balloon 11 is usually 2 cm, the distance between the first pod 21 and the second pod 22 is 5 mm, and the width of the first pod 21 and the second pod 22 in the direction of the artery simulation structure 5 is preferably not more than 1.5 cm, so that the balloon 11 in the artery simulation structure 5 can be located inside the first pod 21 and the second pod 22 at the same time, facilitating comprehensive detection of the artery simulation structure 5 at the corresponding position.

[0068] The gland structure 6 is used to limit the artery simulation structure 5. Figure 2 As shown, the gland structure 6 includes a limiting gland 61 installed on the bracket 4 and a limiting arc chamber 62 arranged in the limiting gland 61; a limiting plate 63 is provided on the bracket 4, and the artery simulation structure 5 is provided between the limiting plate 63 and the limiting arc chamber 62, and there is a gap between the limiting plate 63 and the limiting arc chamber 62.

[0069] In the present invention, a limiting cavity 7 is formed between the limiting plate 63 and the limiting arc chamber 62, and the inner wall of the limiting cavity 7 does not contact the artery simulation structure 5. In addition, in the present invention, the second cylindrical chamber 22 is completely mounted outside the artery simulation structure 5, that is, the pressure cover structure 6 and the bracket 4 play a limiting role, and the second cylindrical chamber 22 plays a fixing role.

[0070] In the present invention, the first pressure sensor 24 monitors the pressure data of the outer wall of the artery simulation structure 5 in real time, and the pressure value monitored by the second pressure sensor 216 reflects the expansion and contraction of the outer wall of the artery simulation structure 5. The first pressure sensor 24 and the second pressure sensor 216 are connected to the controller 13, and the controller 13 has a built-in wireless transmission module, and the wireless transmission module is communicatively connected to the host computer; the gas detector 32 is connected to the controller 13, and the wireless transmission module transmits the pressure data and gas flow data to the host computer.

[0071] When a first pressure sensor 24 detects a change in pressure value, the gas detector 32 can still detect gas circulation, which means that the pressure change on a certain inner wall of the artery simulation structure 5 cannot determine whether the balloon 11 completely blocks the blood. When the second pressure sensors 216 detect a change in pressure value, the gas detector 32 cannot detect gas circulation, which also means that the overall expansion and contraction action of the artery simulation structure 5 can accurately determine whether the interior of the artery simulation structure 5 is completely filled.

[0072] In the present invention, the gas detector 32 is mainly used to determine whether the balloon 11 blocks the blood, and the pressure value changes of the first pressure sensor 24 and the second pressure sensor 216 in the ideal filling state and the overfilling state are further used to determine the pressure value changes of the outer wall of the artery simulation structure 5 in the corresponding state, whether the pressure is uniform, and the expansion and contraction of the outer wall, so as to more comprehensively determine the changes and results during the filling process of the balloon 11.

[0073] In summary, the main implementation process of the present invention is:

[0074] Fix the abdominal artery 51, the iliac artery 52, and the branch artery 53;

[0075] The gas is delivered to the abdominal artery 51, the iliac artery 52, and the branch artery 53 by the air pump 31. The gas simulates blood. A gas detector 32 is set at the branch artery 53 to detect the gas circulation.

[0076] Performing puncture and placing the balloon 11 into the blood vessel, and inflating the balloon 11 so that the balloon 11 gradually expands;

[0077] The first pressure sensor 24 is attached to the outer wall of the artery simulation structure 5 to monitor the pressure changes at different positions on the outer wall of the artery simulation structure 5 in real time;

[0078] When the outer wall of the artery simulation structure 5 performs a telescopic movement, the detection axis frame 23 at the corresponding position will support and drive the detection axis frame 23 to move outward, drive the detection axis frame 23 to rotate, drive the connecting shaft 26 to rotate, and the arc plate 29 to rotate. During the rotation of the arc plate 29, the inclined surface 210 and the arc plate 29 gradually squeeze the extrusion airbag 214, and squeeze the gas in the extrusion airbag 214 into the connecting airbag 215 through the through groove 213. The air pressure in the connecting airbag 215 increases, so that the overall volume of the connecting airbag 215 increases. The second pressure sensor 216 contacts the connecting airbag 215. When the volume of the connecting airbag 215 continues to increase, the pressure value detected by the second pressure sensor 216 increases. Therefore, the rotation of the detection axis frame 23 can be judged by the change in the pressure value, and then the telescopic movement of the corresponding position of the artery simulation structure 5 can be judged.

[0079] The first pressure sensor 24 and the second pressure sensor 216 are connected to the controller 13, which has a built-in wireless transmission module that transmits pressure data and gas flow data to the host computer;

[0080] The gas detector 32 determines whether the balloon 11 is blocking blood flow. The gas detector 32 should just fail to detect the delivered gas. At this time, the balloon 11 is in an ideal filling state. The pressure value changes of the first pressure sensor 24 and the second pressure sensor 216 are used to further determine the pressure value changes of the outer wall of the artery simulation structure 5 in the ideal filling state, whether the pressure is uniform, and the expansion and contraction of the outer wall.

[0081] When the balloon 11 is still being filled, the artery simulation structure 5 will be in an overfilled state. In the overfilled state, the pressure value changes of the first pressure sensor 24 and the second pressure sensor 216 are used to further judge the pressure value changes of the outer wall of the artery simulation structure 5 in the corresponding state, whether the pressure is uniform, and the expansion and contraction of the outer wall.

[0082] By observing the continuity of gas circulation and the changes in the outer wall pressure value of the corresponding arterial simulation structure 5, whether the pressure is uniform, and the expansion and contraction of the outer wall, the changes and results during the filling process of the balloon 11 can be more comprehensively judged. For example, in the first detection scenario, the gas detector 32 detects that the balloon 11 can just block the gas, and maintains this state, the balloon 11 is no longer filled, and leakage occurs for a long time. In the second detection scenario, the gas detector 32 detects that the balloon 11 can just block the gas, and then the balloon 11 continues to be filled to a certain volume, maintaining an overfilled state, and no leakage occurs for a period of time. Based on the changes in the outer wall pressure value of the arterial simulation structure 5, whether the pressure is uniform, and the expansion and contraction of the outer wall under the first and second detection scenarios, the corresponding values that can always maintain the blood blocking state can be further judged.

[0083] That is to say, based on the combined analysis of multiple data such as gas circulation conditions, changes in the outer wall pressure value of the artery simulation structure 5, whether the pressure is uniform, and the expansion and contraction of the outer wall, the filling state of the balloon 11 can be adjusted so that the interior of the artery simulation structure 5 is always in a blood-blocking state.
