[0017] Please refer to Figures 1 to 3. Figure 1 is a block diagram illustrating the lumbar puncture simulation training system 100 according to the first embodiment of the present invention; Figure 2 is a scenario diagram illustrating the lumbar puncture simulation training system 100 according to Figure 1; Figure 3 is a schematic diagram illustrating the virtual scene 20 of the lumbar puncture simulation training system 100 according to Figure 1; Figure 4 is another schematic diagram illustrating the virtual scene 20 of the lumbar puncture simulation training system 100 according to Figure 1. The lumbar puncture simulation training system 100 includes a sensor 110, an information processing device 120, and a display device 130. The sensor 110 is used to sense a hand gesture of a user 10 and convert it into gesture sensing information D1. The information processing device 120 is signal-connected to the sensor 110 and includes an analysis module 121 and an image output module 122. The analysis module 121 is used to analyze the gesture sensing information D1. The image output module 122 is signal-connected to the analysis module 121 and is used to output a virtual scene 20. The virtual scene 20 includes a virtual hand 21, a virtual patient 22, a virtual puncture needle 27, a virtual pressure gauge 26, and a virtual test tube 25. The display device 130 is signal-connected to the image output module 122 and is used to display the virtual scene 20 from the image output module 122. The virtual hand 21 moves within the virtual scene 20 according to gesture sensing information D1 and performs a virtual lumbar puncture. The analysis module 121 moves the virtual hand 21 within the virtual scene 20 according to gesture sensing information D1 to pick up the virtual puncture needle 27 and puncture it into a lumbar vertebral region 22a of the virtual patient 22. The virtual pressure gauge 26 is picked up to measure the pressure value of a cerebrospinal fluid in the virtual puncture needle 27, and a virtual cerebrospinal fluid (not shown) flowing out of the virtual puncture needle 27 is collected in the virtual test tube 25. When the virtual puncture needle 27 is close to the lumbar spine 22a of the virtual patient 22, the image output module 122 displays a lumbar vertebral image Im corresponding to the lumbar spine 22a (see Figure 5).
[0018] Specifically, sensor 110 may be an image sensing device, a handheld sensing grip or other motion sensing device; information processing device 120 may include any type of processor, microprocessor or smart device having a virtual reality processor or a mixed reality processor; display device 130 may include at least one of a wearable virtual reality display, a wearable mixed reality display and a projection display, but the present invention is not limited thereto.
[0019] In detail, when user 10 trains using the lumbar puncture simulation training system 100, a wearable virtual helmet with a display device 130 can be worn on the head. Sensor 110 can sense the user 10's hand movements, convert them into gesture sensing information D1, and transmit them to the analysis module 121 of the information processing device 120 for analysis. The image output module 122 of the information processing device 120 outputs the virtual scene 20 as shown in Figure 3 to the display device 130, and the display device 130 displays the virtual scene 20. In Figure 3, the virtual scene 20 includes a virtual hand 21, a virtual patient 22 lying on a virtual hospital bed 30, and the lumbar spine 22a of the virtual patient 22.
[0020] Please refer to Figures 1 through 6, where Figure 5 is a further schematic diagram of the virtual scene 20 of the lumbar puncture simulation training system 100 according to Figure 1; and Figure 6 is yet another schematic diagram of the virtual scene 20 of the lumbar puncture simulation training system 100 according to Figure 1. Specifically, the simulation process of lumbar puncture may include marking the puncture site, disinfecting the lumbar spine 22a, puncture, withdrawing the puncture guide needle, measuring the cerebrospinal fluid pressure, and collecting cerebrospinal fluid, but the present invention is not limited thereto. The user 10 can use the virtual hand 21 to find the correct vertebral position to be punctured in the lumbar spine 22a of the virtual patient 22 in the virtual scene 20, and mark the position to be punctured, as shown in Figure 3. Next, user 10 can adjust the viewpoint in the virtual scene 20 by rotating their head, moving the viewpoint to the tool table 31, and moving the virtual hand 21 to pick up the virtual disinfection tool 24 on the tool table 31 to disinfect the lumbar spine area 22a of the virtual patient 22, as shown in Figure 4. After the lumbar spine area 22a is disinfected, user 10 can operate the virtual hand 21 to insert the virtual puncture needle 27 into the body of the virtual patient 22. When the virtual hand 21 moves to a position close to the lumbar spine area 22a, the skin image of the lumbar spine area 22a of the virtual patient 22 in the virtual scene 20 is converted into a lumbar spine bone image Im, as shown in Figure 5. In Figure 6, after the virtual puncture needle 27 punctures the spinal cord of the virtual patient 22, the user 10 can operate the virtual hand 21 to pull out the puncture guide needle on the virtual puncture needle 27 and connect it to the virtual pressure gauge 26 to measure the pressure value of the cerebrospinal fluid in the virtual patient 22. After the puncture guide needle is pulled out, the virtual cerebrospinal fluid in the virtual patient 22 will flow out from the puncture guide needle of the virtual puncture needle 27. The user 10 can operate the virtual hand 21 to pick up the virtual test tube 25 to collect the virtual cerebrospinal fluid flowing out of the virtual puncture needle 27. In other embodiments of the present invention, when the virtual puncture needle is punctured into the wrong bone joint position, the virtual scene can display the image of blood flowing out of the virtual puncture needle, but the present invention is not limited thereto. Thus, the lumbar puncture simulation training system 100 of the present invention allows the user 10 to perform highly realistic simulation practice of lumbar puncture, enabling the operator to become familiar with the operation procedure and improve the puncture accuracy of the operator when performing lumbar puncture in actual operation.
[0021] In other embodiments of the present invention, the analysis module 121 can drive the image output module 122 to output a prompt message based on the virtual puncture needle 27 being inserted into a body part of the virtual patient 22. Specifically, when the virtual puncture needle 27 is inserted into the correct vertebral position of the lumbar spine 22a of the virtual patient 22, the image output module 122 can display a prompt message in the virtual scene 20 indicating that the puncture position is correct for the user 10. When the virtual puncture needle 27 is inserted into the wrong vertebral position of the lumbar spine 22a of the virtual patient 22 or into other body parts of the virtual patient 22, the image output module 122 can display a prompt message in the virtual scene 20 indicating that the puncture position is incorrect for the user 10.
[0022] In addition, the information processing device 120 may further include a voice output module (not shown). The voice output module is signal-connected to the analysis module 121 and is used to output a voice guidance message based on the gesture sensing information D1. The user 10 is guided by the voice guidance message and moves to the lumbar spine position 22a of the virtual patient 22. Specifically, the voice guidance message may include instructions for the user 10 to perform pre-puncture preparation, explanations of all actions during the puncture operation, and voice teaching to explain and guide the virtual patient 22 during the simulated puncture process. In this way, the lumbar puncture simulation training system 100 of the present invention, in addition to practicing finding the puncture position of the lumbar spine position 22a, also allows the user 10 to simulate and practice the process of guiding the patient and responding.
[0023] In other embodiments of the present invention, the user 10 can further drive the virtual hand 21 to pick up a virtual disinfectant towel (not shown), a virtual sterile drape (not shown), and a virtual anesthetic agent 23 in the virtual scene 20 according to voice guidance messages to perform a pre-puncture operation training. The lumbar puncture simulation training system 100 can also allow the user 10 to simulate aseptic pre-procedure operations on the virtual patient 22 before lumbar puncture, such as placing a virtual sterile drape, disinfecting the lumbar spine area 22a through a virtual disinfectant towel, and injecting the virtual anesthetic agent 23, but the present invention is not limited thereto.
[0024] In other embodiments of the present invention, the analysis module 121 can adjust the movement speed of the virtual hand 21 and the virtual puncture needle 27 in the virtual scene 20 according to a puncture depth of the virtual puncture needle 27 piercing the lumbar spine 22a of the virtual patient 22, thereby simulating the resistance when the puncture needle is actually inserted into the epidural space. Thus, the lumbar puncture simulation training system 100 of the present invention allows the user 10 to determine the puncture depth based on tactile feedback.
[0025] Please refer to Figures 1 and 7. Figure 7 is a flowchart illustrating the lumbar puncture simulation training method S10 of the second embodiment of the present invention. The lumbar puncture simulation training method S10 includes steps S01, S02, S03, S04, S05, and S06. Step S01: The user 10's hand posture is sensed by the sensor 110 and converted into gesture sensing information D1. Step S02: The gesture sensing information D1 is analyzed by the analysis module 121 of the information processing device 120. Step S03: The virtual scene 20 is output by the image output module 122 of the information processing device 120. The virtual scene 20 includes a virtual hand 21, a virtual patient 22, a virtual puncture needle 27, a virtual pressure gauge 26, and a virtual test tube 25. Step S04: When the virtual puncture needle 27 approaches the lumbar spine 22a of the virtual patient 22, the image output module 122 displays the lumbar vertebral image Im corresponding to the lumbar spine 22a. Step S05: The analysis module 121 moves the virtual hand 21 according to the gesture sensing information D1 to pick up the virtual puncture needle 27 in the virtual scene 20 and inserts it into the lumbar spine 22a of the virtual patient 22. The virtual pressure gauge 26 is used to measure the pressure value of the cerebrospinal fluid in the virtual puncture needle 27, and the virtual cerebrospinal fluid flowing out of the virtual puncture needle 27 is collected in the virtual test tube 25 to perform a virtual lumbar puncture. Step S06: The display device 130 displays the virtual scene 20 from the image output module 122.
[0026] In other embodiments of the present invention, the lumbar puncture simulation training method may further include using a voice output module of an information processing device to output a voice guidance message based on gesture sensing information. The user is guided by the voice guidance message and moves to the lumbar region of a virtual patient; the analysis module drives a virtual hand to pick up a virtual disinfectant wipe, a virtual sterile drape, and a virtual anesthetic in the virtual scene for pre-puncture operation training; the analysis module drives an image output module to output a prompt message based on the virtual puncture needle piercing a body part of the virtual patient; the analysis module adjusts the movement speed of the virtual hand and the virtual puncture needle in the virtual scene based on the puncture depth of the virtual puncture needle piercing the lumbar region of the virtual patient.
[0027] As can be seen from the above embodiments, the present invention has the following advantages: First, the lumbar puncture simulation training system and method of the present invention can provide users with highly realistic simulation practice of lumbar puncture, allowing operators to become familiar with the operation process and improve the puncture accuracy of operators when actually performing lumbar puncture; Second, in addition to practicing finding the puncture location in the lumbar region, the lumbar puncture simulation training system and method of the present invention can also provide users with simulated practice of guiding patients and responding to questions; Third, the lumbar puncture simulation training system and method of the present invention can allow users to judge the puncture depth based on tactile feedback.
[0028] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims. [Simplified Explanation of the Diagram]
