[0002] In clinical medicine, in order to drain abdominal effusion or take a biopsy of an abdominal mass, experienced doctors need to use puncture equipment to puncture the abdomen to drain the abdominal effusion or take a puncture sample of the mass. Since the puncture angle and technique require time to accumulate, some novices may feel unable to cope. Therefore, abdominal puncture models are usually used for repeated training and practice to proficiently master the puncture technique before treating patients.

[0003] When performing abdominal model puncture training under ultrasonic guidance, according to the detection of the ultrasonic probe on the abdominal model image, the puncture needle is used to perform puncture training on the abdominal model. However, for training personnel, it may be difficult to determine whether the puncture depth of the puncture needle reaches the specified position, and multiple puncture trainings are required to master the control of the puncture depth, which may not be convenient for improving the training accuracy of the training personnel.

First switches 283 are installed in the disc 281 at the positions of the grooves 282. Resistors 287 are equidistantly arranged around the circumference on the outer side of the disc 281. The resistance values of the three resistors 287 are different from each other and are respectively electrically connected to the three first switches 283. And the three first switches 283 of the first touch control 28 on the side close to the frame 21 are electrically connected to the first electromagnet 299 of the first control member 29. The three first switches 283 of the first touch control 28 on the other side are electrically connected to the first electromagnet 299 of the second control member 217; A cylinder 284 is abutted and arranged on the upper side of the disc 281.

When opening, the closing cover 286 can be directly rotated in the reverse direction to open. Through the cooperation of the clamping block and the buckle, the rotation opening or closing of the closing cover 286 can be facilitated; A first connecting member 27 is arranged between the two cylinders 284. The first connecting member 27 includes a connecting plate 272 fixedly arranged with the two cylinders 284. A first telescopic tube 271 is fixedly arranged between the connecting plate 272 and the mounting member 25. Limiting grooves are symmetrically arranged on the inner side of the fixed end of the first telescopic tube 271.

A first spring 273 is fixedly arranged in the first telescopic tube 271. The two ends of the first spring 273 are respectively fixed to the fixed end and the telescopic end of the first telescopic tube 271;

[0041] During use, for simulating different degrees of abdominal effusion, the first touch control 28 near one side of the frame body 21 and the first control member 29 in the water accumulation cylinder 26 are involved in the operation. The gravity ball 285 is placed through the opening on the upper side of the cylinder body 284 on the side away from the frame body 21. Through the cylinder body 284, the gravity ball 285 can randomly fall into a groove 282 and press against the first switch 283 in one groove 282, making the first electromagnet 299 of the first control member 29 energized and connecting a resistor 287 connected to this first switch 283 into the circuit. Thus, the repulsive force generated by the energized first electromagnet 299 on the first magnet 298 can be randomly regulated. When the resistance value of the resistor 287 is relatively large, the repulsive effect of the first electromagnet 299 on the first magnet 298 is relatively small, causing the mounting plate 291 to move downward by a relatively small distance. The downward movement of the mounting plate 291 can cause the support column 294 to press against the second switch 292, the third spring 219 to elongate, the water pump 211 to operate, and the solenoid valves on the connecting pipe 212 and the water delivery pipe 213 on one side of it to open, pumping the water in the water accumulation cylinder 26 to the upper side of the bottom plate 23. As the water level in the water accumulation cylinder 26 drops, the floating body 214 moves downward. At the same time, due to the repulsive effect of the first electromagnet 299 on the first magnet 298, the mounting plate 291 moves downward accordingly, keeping the second switch 292 still in the state of being pressed by the support column 294, and the water pump 211 continues to pump the water to the upper side of the bottom plate 23. Under the repulsive effect of the first electromagnet 299 on the first magnet 298, after the mounting plate 291 moves downward to the maximum distance, it will no longer move downward. As the floating body 214 moves downward, the support column 294 no longer presses against the second switch 292, the water pump 211 stops operating, and the solenoid valve on the connecting pipe 212 on one side of it is controlled to close. The second telescopic pipe 295 continues to maintain the state of pressing against the third switch 293. Thus, when the resistance value of the resistor 287 is relatively large, less water can be pumped to the upper side of the bottom plate 23. On the contrary, when the resistance value of the resistor 287 is relatively small, more water can be pumped to the upper side of the bottom plate 23. Therefore, the amount of water between the upper side of the bottom plate 23 and the corrugated plate 24 can be randomly regulated to simulate different degrees of abdominal effusion;

[0042] Similarly, when simulating different positions in the upper abdomen, middle abdomen or lower abdomen where the abdominal fluid is located, the first touch control 28 on the side away from the frame 21 and the second control 217 inside the frame 21 participate in the operation. The gravity ball 285 is placed through the opening on the upper side of the cylinder 284 on the side close to the frame 21. The gravity ball 285 can randomly fall into a groove 282 and press against the first switch 283 in one of the grooves 282, causing the first electromagnet 299 of the second control 217 to be energized and connecting a resistor 287 connected to this first switch 283 to the circuit. Through the repulsive force of the first electromagnet 299 of the second control 217 on the first magnet 298, the mounting plate 291 of the second control 217 moves upward, and the fourth spring 222 stretches, causing the support column 294 to press against the second switch 292, causing the electric push rod 221 to work and driving the bottom plate 23 to move upward. After the mounting plate 291 of the second control 217 moves upward to the maximum distance, as the bottom plate 23 moves upward, the support column 294 no longer presses against the second switch 292, and the electric push rod 221 stops working. When the resistance value of the randomly connected resistor 287 is large, the upward movement distance of the mounting plate 291 is small, so the upward movement distance of the bottom plate 23 is small. On the contrary, when the resistance value of the connected resistor 287 is small, the upward movement distance of the bottom plate 23 can be large, so that the different positions in the upper, middle and lower parts of the abdomen where the fluid is located can be simulated;

[0043] After that, the trainer can wear rubber gloves, cooperate with the ultrasonic probe 12 and the display device 13, and perform puncture training on the puncture block 22 with the puncture needle 11. When the puncture needle 11 reaches the position where the water body is located in the corrugated plate 24, the conductive block 215, the puncture needle 11 and the first indicator light 225 form a closed circuit, and the first indicator light 225 lights up, which can prompt the trainer that the puncture reaches the specified position. And through the setting of the two first touch controls 28, the different degrees of the water body on the upper side of the bottom plate 23 can also be randomly combined with the different positions where the bottom plate 23 is located to simulate the puncture training under different conditions of abdominal fluid, improving the puncture training accuracy of the trainer;

[0044] After the puncture training is completed, the connecting plate 272 of the first connecting member 27 can be lifted upward, so that the two side cylinders 284 are lifted upward, the gravity balls 285 are taken out, and then under the elastic force of the first spring 273, the cylinders 284 move downward to reset. After taking out the two gravity balls 285, the first switch 283 will no longer be pressed, so that the first electromagnetic block 299 of the first control member 29 and the second control member 217 is powered off. Under the elastic force of the third spring 219, the mounting plate 291 of the first control member 29 moves upward to reset, so that the second telescopic tube 295 no longer presses the third switch 293, causing the drain pump 210 to work and controlling the solenoid valve on the communicating pipe 212 and the water pipe 213 on one side thereof to open, and discharging the water body on the upper side of the bottom plate 23 into the water collecting cylinder 26. After the discharge is completed, the floating body 214 moves upward to the uppermost side, and the second telescopic tube 295 presses the third switch 293 again, causing the drain pump 210 to stop working; similarly, under the elastic force of the fourth spring 222, the mounting plate 291 of the second control member 217 moves downward to reset, releasing the pressing action of the second telescopic tube 295 on the third switch 293, and the telescopic end of the electric push rod 221 drives the bottom plate 23 to move downward to reset. When the bottom plate 23 moves downward and the second telescopic tube 295 presses the third switch 293 again, the electric push rod 221 stops working and returns to the initial state.

The disc 281 of the second touch control member 31 is fixed on the upper side of the mounting member 25. A second connecting member 32 is provided between the second touch control member 31 and the first touch control member 28 on the side away from the frame 21. The second connecting member 32 has the same structure as the first connecting member 27. The connecting plate 272 of the second connecting member 32 is fixed to the second touch control member 31 and the cylinder 284 on the side away from the frame 21. Guide blocks 33 are symmetrically fixed on one side of the cylinders 284 of the first touch control member 28 and the second touch control member 31. A support block 34 is slidably arranged in the guide block 33. The support block 34 movably penetrates through one side of the cylinder 284. The support block 34 is adapted to the gravity ball 285. The two support blocks 34 on one side of one cylinder 284 can support the gravity ball 285; A dial plate 35 is fixed between the three support blocks 34 on both sides. Fixed blocks 36 are fixed on the upper side of the connecting plates 272 of the first connecting member 27 and the second connecting member 32. A limiting member 37 that movably penetrates through the fixed block 36 is fixed on one side of the dial plate 35. A fifth spring 38 is fixed between the dial plate 35 and the fixed block 36. The fifth spring 38 is sleeved on the outer side of the limiting member 37. The fifth spring 38 is used for the reset of the dial plate 35. A protrusion is arranged at one end of the limiting member 37 away from the dial plate 35 to prevent the limiting member 37 from detaching from the fixed block 36, and further prevent the support block 34 from detaching from the guide block 33;

[0047] By moving the dial plate 35 between the two first touch controls 28 away from the cylinder 284, the two support blocks 34 on the cylinder 284 near the side of the frame 21 move outward, the support for the gravity ball 285 can be released, and the gravity ball 285 falls. By moving one support block 34 on the side of the frame 21 at the middle position outward, the gravity ball 285 on the cylinder 284 at the middle position can fall from the side of the moved support block 34, and through the guidance of the cylinder 284, the gravity ball 285 can fall from the middle of the disk 281 directly opposite, so that different degrees of intra-abdominal fluid and different intra-abdominal positions can be randomly combined; similarly, through the dial plate 35 between the second touch control 31 and the first touch control 28, different positions in the upper abdomen, middle abdomen or lower abdomen where the abdominal mass is located and different positions on the left and right can be randomly combined to simulate the puncture training at different positions of the abdominal mass.

[0048] On the upper side of the bottom plate 23, a third telescopic tube 39 is fixedly installed. Inside the fixed end of the third telescopic tube 39, sliding grooves 310 are symmetrically arranged. The telescopic end of the third telescopic tube 39 slides along the sliding grooves 310, which can guide the telescopic movement of the telescopic end of the third telescopic tube 39. Inside the third telescopic tube 39, a sixth spring 311 is fixedly installed. The two ends of the sixth spring 311 are respectively fixed to the fixed end and the telescopic end of the third telescopic tube 39. Fixed sleeves of bellows 312 are installed on the outer sides of the fixed end and the telescopic end of the third telescopic tube 39. When the third telescopic tube 39 expands and contracts, the bellows 312 expands and contracts, and the bellows 312 can prevent water from seeping into the sliding connection between the fixed end and the telescopic end of the third telescopic tube 39;

[0049] The telescopic end of the third telescopic tube 39 is fixedly provided with a connecting block 313. A second magnetic block 315 is fixedly arranged inside the connecting block 313. The connecting block 313 can protect the second magnetic block 315. A second electromagnetic block 316 is arranged on one side of the second magnetic block 315. A protective shell 314 fixedly sleeved outside the second electromagnetic block 316 is fixedly arranged with the bottom plate 23. The protective shell 314 can protect the second electromagnetic block 316. Through holes can be arranged on the lower side of the protective shell 314 and the bottom plate 23 where the second electromagnetic block 316 is located for heat dissipation of the second electromagnetic block 316, and it can also prevent water from affecting the second electromagnetic block 316. The magnetic effects of the second electromagnetic block 316 and the second magnetic block 315 can pass through the protective shell 314 and the connecting block 313. The three first switches 283 and the resistor 287 of the second touch control 31 are electrically connected to the second electromagnetic block 316. After being powered on, the second electromagnetic block 316 can generate a repulsive force on the second magnetic block 315. A block 317 is fixedly arranged on the upper side of the connecting block 313. The block 317 is used to simulate an abdominal mass. The block 317 can be made of silica gel material. The block 317 and the connecting block 313 can be fixed by gluing. After multiple puncture trainings, the block 317 can be disassembled and replaced. A conductive shell 318 is fixedly arranged inside the block 317. A second indicator light 319 is installed at the upper end of the mounting member 25. The second indicator light 319 is electrically connected to the puncture needle 11 through a wire and is also electrically connected to the conductive shell 318;

[0050] Through the second touch control 31, the gravity ball 285 can randomly fall into the groove 282 on the disc 281 and press against the first switch 283 in the groove 282, causing the second electromagnetic block 316 to be energized to generate a repulsive force on the second magnetic block 315, so that the connecting block 313 drives the block 317 to move away from the protective shell 314, the third telescopic tube 39 extends, and the sixth spring 311 extends. Through the random pressing of the first switch 283 by the gravity ball 285 and the random access of a resistor 287, the repulsive force of the second electromagnetic block 316 on the second magnetic block 315 can be randomly regulated, thereby regulating the moving distance of the block 317 to simulate different positions of the abdominal mass left and right. And through the combination with the first touch control 28 on the side away from the frame 21, the different positions of the upper, middle, and lower parts and the different positions of the left and right where the abdominal mass is located can be randomly combined, improving the puncture training effect of the training personnel; then, in cooperation with the ultrasonic probe 12 and the display device 13, puncture training is carried out on the block 317 with the puncture needle 11 to simulate the puncture of the abdominal mass. When the puncture needle 11 touches the conductive shell 318, the conductive shell 318, the puncture needle 11 and the second indicator light 319 form a closed circuit, and the second indicator light 319 lights up, indicating that the depth position of the block 317 has been punctured, so as to provide a training simulation prompt for the deep puncture sampling of the mass during the puncture biopsy of the mass. When the second indicator light 319 does not light up after the block 317 is punctured, the epidermal sampling of the mass can be trained and simulated, thereby improving the puncture training accuracy of the training personnel; similarly to the model component 2, after the gravity ball 285 is taken out, the pressing effect on the first switch 283 of the second touch control 31 can be released, the second electromagnetic block 316 is powered off, and under the elastic force of the sixth spring 311, the connecting block 313 drives the block 317 to move in the reverse direction and reset.
