[0007] Preferably, the compartments are all connected to the interior of the central body through connecting tubes, solenoid valves are provided inside the connecting tubes, openings are provided on the outer periphery of the central body, and the interior of the central body is connected to the interior of the liner through the openings.

[0008] Preferably, a through tube is slidably connected inside the catheter, one end of the through tube away from the catheter is fixedly connected to the prostate model, the catheter is connected to the interior of the liner, and a solenoid valve is installed inside the through tube.

[0009] Preferably, a limiting tube is fixedly connected to the middle of one end of the through tube away from the prostate model, one end of the limiting tube away from the through tube passes through the end of the catheter, and the limiting tube is slidably connected to the catheter.

At the same time, people can lower the mounting table through the lifting table, and then start the electric slide.

[0018] 4. When actually adjusting the position and volume data of the prostate model, by controlling the opening and closing of the electromagnetic valve inside the connecting tube, the inflation volume of each compartment inside the prostate model can be adjusted and changed, so that people can adjust the body shape and position data of the prostate model accordingly according to the patient's prostate data, simulate the patient's condition, and perform simulated surgery before the actual surgery, which can effectively improve the success rate of the actual surgery and help improve the actual simulation results.

The outer periphery of the middle body 125 is provided with an opening. The inner part of the middle body 125 is connected with the inner part of the liner 121 through the opening.

[0030] Furthermore, in a specific implementation, people can also open the electromagnetic valve inside the through tube 118, and the gas pumped by the air pump will enter the through tube 118 through the through hole 120. After entering the through tube 118, the gas will enter the inner liner 121, and the gas inside the inner liner 121 can be introduced into the prostate model 114 through the middle through body 125 and the connecting tube 124 inside the inner liner 121, so that the prostate model 114 can be propped up and enlarged, and the size of the prostate model 114 can be changed, so that the prostate data of patients of different ages and conditions can be simulated, which is conducive to further providing a template for simulation training. The "mother body" faced in each training can be changed, which is conducive to improving the fun and uncertainty of multiple trainings. When actually adjusting the position and volume data of the prostate model 114, by controlling the opening and closing of the electromagnetic valve inside the connecting tube 124, the inflation volume of each compartment 122 inside the prostate model 114 can be adjusted and changed, so that people can adjust the body shape and position data of the prostate model 114 according to the patient's prostate data, simulate the patient's condition, and thus perform simulated surgery before the actual surgery, thereby effectively improving the success rate of the actual surgery and helping to improve the actual simulation results.

[0032] Furthermore, in the specific implementation, when the simulated puncture training is actually carried out, the prostate model 114 inside the human body model 102 can simulate the prostate to be punctured in the patient's body, so as to provide the trainee with a puncture target. During the puncture training, people can start the air pump, and the air pump can use the ventilation tube 110 to pump air into the catheter 115. At this time, the solenoid valve inside the through tube 118 is in a closed state. After the gas enters the catheter 115, it will push the through tube 118 to move inside the catheter 115, so that the through tube 118 will move outward. When the air pump driving part is reversed, the gas inside the catheter 115 will be extracted, thereby driving the through tube 118 and the through tube 118 to move outward. The prostate model 114 retracts, thereby driving the prostate model 114 at the end to move. The magnetic attraction of the fixing rod 117 can make the prostate model 114 slide along the fixing rod 117, thereby driving the position of the prostate model 114 inside the human body model 102 to change.

An electric slide 126 is connected to the end of the guide rail 105. The electric slide 126 is installed on the side of the top of the guide rail 105 away from the lifting platform 106. The lifting part of the top of the lifting platform 106 is fixedly connected to the mounting platform 108, and a targeting frame 107 is installed in the middle of the top of the mounting platform 108. A guide platform 109 is arranged in the middle of the targeting frame 107. The guide platform 109 is used to guide the acoustic wave puncture probe;

[0034] Furthermore, in specific implementation, people can simulate the prostate puncture operation process under the guidance of image fusion technology through the puncture practical simulation device 1, which helps doctors master prostate puncture skills, helps improve the accuracy and safety of actual clinical operations, and reduces the risk of complications of patients during the puncture process.

The targeting frame 107 and the guide platform 109 can cooperate with the display screen 104 to provide targeted guidance for the puncture needle during the puncture training process, helping people to perform targeted puncture guidance training. At the same time, people can lower the mounting platform 108 through the lifting platform 106, and then start the electric slide 126. The lifting platform 106 and the mounting platform 108 can be retracted to the bottom of the bed 101 through the work of the electric slide 126. At this time, it is convenient for people to use the puncture practical simulation device 1 to train conventional prostate puncture operations, so that the puncture practical simulation device 1 can assist people in switching training between the two puncture modes, which is conducive to actual use.

[0035] Working principle:

[0036] In actual use, people can simulate the prostate puncture operation process under the guidance of image fusion technology through the puncture practical simulation device 1, help doctors master prostate puncture skills, help improve the accuracy and safety of actual clinical operations, and reduce the risk of complications of patients during the puncture process. During simulation training, the human body model 102 can help people cooperate with the puncture practical simulation device 1 to conduct prostate puncture operation training under the guidance of image fusion technology, the display screen 104 can display the detection picture transmitted by the sonic puncture probe during puncture, the lighting lamp 103 can assist in supplementing the surrounding environment with light, simulate the actual surgical scene, and help improve the simulation training. The targeting frame 107 and the guide table 109 can be used to During the puncture training, the display screen 104 provides targeted guidance for the puncture needle to help people conduct targeted puncture guidance training. At the same time, people can lower the mounting platform 108 through the lifting platform 106, and then start the electric slide 126. The lifting platform 106 and the mounting platform 108 can be retracted to the bottom of the bed 101 through the operation of the electric slide 126. At this time, it is convenient for people to use the puncture practical simulation device 1 to train conventional prostate puncture operations, so that the puncture practical simulation device 1 can assist people in switching training between the two puncture modes, which is beneficial to actual use. When actually conducting simulated puncture training, the prostate model 114 inside the human body model 102 can simulate the prostate to be punctured in the patient's body, which is used to provide training for the trainees. For puncture targets, during puncture training, people can start the air pump, and the air pump can use the ventilation tube 110 to pump air into the catheter 115. At this time, the electromagnetic valve inside the through tube 118 is in a closed state. After the gas enters the catheter 115, it will push the through tube 118 to move inside the catheter 115, so that the through tube 118 will move outward. When the air pump driving part is reversed, the gas inside the catheter 115 will be extracted, thereby driving the through tube 118 and the prostate model 114 to retract, thereby driving the prostate model 114 at the end to move, and the magnetic attraction of the fixing rod 117 can make the prostate model 114 slide along the fixing rod 117, so that the prostate model 114 can be driven to move in the position inside the human body model 102. The different physical conditions of different patients can be simulated through a set of models, so that more body data templates can be provided for trainers, which is conducive to quickly improving the puncture experience of trainers. The puncture part 127 is a replaceable component. After more puncture training, people can extend the service life of the human body model 102 by replacing the puncture part 127. At the same time, people can also open the electromagnetic valve inside the through pipe 118. At this time, the gas pumped by the air pump will enter the through pipe 118 through the through hole 120. After entering the through pipe 118, the gas will enter the inner liner 121. The gas inside the inner liner 121 can be introduced into the prostate model 114 through the middle through body 125 and the connecting pipe 124 inside the inner liner 121.Thus, the prostate model 114 can be propped up and expanded to achieve the change of the size of the prostate model 114, so as to simulate the data of the prostate of patients of different ages and conditions, which is conducive to further providing a template for simulation training, so that the "maternal body" faced in each training can be changed, which is conducive to improving the fun and uncertainty of multiple trainings. When the position and volume data of the prostate model 114 are actually adjusted, the opening and closing of the electromagnetic valve inside the connecting tube 124 can be controlled to achieve the adjustment and change of the inflation volume of each compartment 122 inside the prostate model 114, so that people can adjust the body shape and position data of the prostate model 114 according to the prostate data of the patient, simulate the patient's condition, and perform simulated surgery before the actual surgery, so as to effectively improve the success rate of the actual operation, which is conducive to improving the actual simulation effect.
