The virtual blood vessel module 10 is produced by using 3D printing technology according to the blood vessels that a patient will pass through when undergoing a catheter operation, and it includes a first tube that can contain a blood-like liquid L to flow. 11. A second tube body 12 covering the first tube body 11, a second tube body 12 arranged on the first tube body 11 and the first tube body 11 The first accommodating space 13 and the two sensing portions 14 between the two pipes 12, wherein each of the sensing portions 14 is provided with a second accommodating space 141 and a first connection connected to the second accommodating space 141 The connecting pipe 142, the first connecting pipe 142 is formed protruding outward from the second pipe body 12; and the sensing portion 14 further includes a first sealing element 143 and a second sealing element 144, the first sealing element 143 and the second sealing element 144 are integrally formed between the outer circumferential wall of the first tube 11 and the inner circumferential wall of the second tube 12, so that the second accommodating space 141 is covered from the first accommodating space 13 Separately, the immersive blood vessel module 10 in this implementation is 3D printed according to the blood vessels that the heart catheterization will pass through. It can also be 3D printed according to the blood vessels that the brain catheterization will pass through. The blood vessel module 10 can also be provided with one or a plurality of the sensing parts 14, but it is not limited to this, that is, the realistic blood vessel module 10 can be produced by a mold injection molding method.

The control module 20 is connected to the virtual blood vessel module 10 and controls the flow rate of the liquid L in the first tube 11, thereby enabling the doctor or user to insert the catheter G into the virtual blood vessel module 10 , The control module 20 will control the flow rate of the liquid L, so that the liquid L will flow similar to the flow rate of human blood, and achieve a more realistic effect; the sensing warning module 30, please refer to Figure 2 again Shown, including a second connecting pipe 31 and a sensing and warning unit 32, wherein one end of the second connecting pipe 31 is connected to the first connecting pipe 142 of the sensing portion 14, and the other end is connected to the sensing and warning unit 32; and the sensing and warning unit 32 is provided with a pressure sensor 33, the pressure sensor 33 is electrically connected to the sensing and warning unit 32, therefore, the sensing and warning module 30 can be based on the sensing portion 14 The sensing and warning units 32 corresponding to different pressure differences are set at different positions. For example, this embodiment is provided with three sensing and warning units 32, which means that the sensing and warning module 30 is initialized for three different pressure differences. The value of will correspond to the sensing and warning unit 32, but is not limited to this; wherein, the second accommodating space 141 is formed in the first accommodating space 13; therefore, the sensing and warning unit 32 will According to the pressure of the second accommodating space 141 detected by the pressure sensor 33 When there is a change, the sensing and warning module 30 will calculate the value of its pressure difference, and then the corresponding sensing and warning unit 32 will generate a warning signal.

The corresponding lamp of the sensing and warning unit 32, but not limited to this.

For the operation, please refer to Figure 2, Figure 3-1 and Figure 3-2. The virtual blood vessel module 10 is taken according to the blood vessels through which the catheter G will pass when the patient is undergoing catheter surgery. The blood vessel is produced by 3D printing technology. The immersive blood vessel module 10 can also be manufactured according to other requirements or methods; the control module 20 will control the speed of the liquid L flowing in the first tube 11 to make the liquid L The speed of flow is similar to the speed of blood flow in a human blood vessel, and each of the sensing parts 14 provided on the virtual blood vessel module 10 will use the first connecting tube 142 to connect to the second connecting tube 31 to generate communication.

Therefore, please refer to Figure 2. When the catheter G is inserted into the first tube body 11 filled with liquid L, it passes through the sensing part 14 because the catheter G does not touch the first tube. Therefore, the second accommodating space 141 is not deformed, so the sensing and warning unit 32 and the pressure sensor 33 do not sense a change in pressure, and the sensing and warning module 30 calculates its pressure If the difference value is zero, the sensing warning unit 32 will not generate a warning signal. Please refer to Figure 3-1 and Figure 3-2. When the catheter G is inserted and advanced, it accidentally touches the sensing part When the wall of the first tube 11 is located at 14, because the first tube 11 is elastic, the catheter G will cause the wall of the first tube 11 to deform in the direction of the second tube 12 , And then compress the second accommodating space 141 to cause the internal pressure to change. At this time, the pressure sensor 33 will detect that the pressure of the second accommodating space 141 is different from the initial pressure, which represents If the catheter G touches the peripheral wall of the first tube body 11, the sensing warning module 30 will be initialized according to the pressure value detected by the pressure sensor 33 when the catheter G touches the peripheral wall The pressure value at the time is calculated to obtain the value of the pressure difference, and then the corresponding sensing and warning unit 32 sends out the warning signal to warn the doctor or user operating the catheter G according to the range of the pressure difference, thereby not only reminding the doctor Or the user's catheter G touches the first tube body 11, and the doctor or user is further reminded of the danger of the pressure difference to the first tube body 11 when the catheter G touches the first tube body 11.

With the above structure, the vascular intervention minimally invasive surgery teaching simulation device 100 of the present invention provides the virtual blood vessel module 10 for doctors or users to practice catheter G insertion, and the virtual blood vessel module 10 is based on the needs of the patient.
