[0002] Medical students need to enhance their skills during their studies and before practicing, requiring a thorough understanding of surgical procedures and processes. This necessitates daily practice and a deep understanding of the human body's internal structure. Currently, some surgical training devices can simulate the surgical environment for doctors to operate on, facilitating the training of accuracy and dexterity before real surgeries. However, traditional surgical training devices rely on manual observation to judge the success of the operation, making it impossible to quantify the accuracy of the operation. Training results are heavily influenced by subjective factors, and it is difficult to record operational data for analysis and improvement. These problems urgently need to be addressed.

For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0028] Please refer to the following: Figure 1 and Figure 2 One embodiment of the bead-throwing training device of this application includes:

[0029] A container 101 for holding beads 102 of at least two colors;

[0030] A bead box 103 of at least two colors is used to receive beads 102 of the corresponding colors that are inserted.

[0031] Color sensor 104 and counting sensor 105 are respectively disposed inside the bead box 103. Color sensor 104 is used to detect whether the color of the bead 102 is consistent with the corresponding color of the bead box 103. Counting sensor 105 is used to count the number of beads 102 inserted.

[0032] The control unit 106 is connected to the color sensor 104 and the counting sensor 105 respectively. When the color sensor 104 sends a color matching signal, the counting sensor 105 is activated to count the number of beads 102.

[0033] Specifically, the bead-throwing training device is an integrated panel with a container 101 and a bead-throwing box 103. The container 101 is a box for placing beads 102 of different colors in the initial state. The container 101 can have only one chamber for placing beads 102 of multiple colors, or it can have two or more chambers for placing beads 102 of different colors in different chambers. Color labels can be set on the chambers for categorized placement.

[0034] The bead box 103 is a container for inserting beads 102. The number of bead boxes 103 is generally matched with the number of colors of beads 102. For example, if there are two colors of beads 102, namely red and green, then there are two types of bead boxes 103, namely red and green. The bead boxes 103 can be placed horizontally, vertically, or at an angle on the panel. In some embodiments, the position of the bead boxes 103 can be moved and arranged according to actual needs.

[0035] The bottom of the bead box 103 can be provided with a through hole, so that after the bead 102 is put into the bead box 103, it can automatically flow back into the receiving box 101 through the through hole.

[0036] During surgical training, doctors use long-handled clamps to pick up beads 102 and place them into the corresponding colored bead box 103. Doctors can alternate between their left and right hands to train their hand-eye coordination and spatial orientation. This surgical training scenario can be used, for example, for laparoscopic surgery training to increase doctors' proficiency in manipulating instruments during actual minimally invasive laparoscopic surgery.

[0037] Existing surgical training devices can only observe the bead-throwing action themselves, but cannot record whether the bead-throwing action is correct, the success rate, the entry between two training sessions, the bead-throwing time, etc. Therefore, in this embodiment, a color sensor 104 and a counting sensor 105 are provided inside the bead-throwing box 103, which can automatically identify whether the bead 102 is put into the bead-throwing box 103 corresponding to the correct color, and automatically count if it is correct.

[0038] The control unit 106 is connected to both the color sensor 104 and the counting sensor 105. When it receives a color matching signal from the color sensor 104, it activates the counting sensor 105 to count the number of beads 102. The control unit 106 is electrically connected to the color sensor 104 and receives signals from it. When the color sensor 104 detects that the color of the bead 102 matches the color of the bead box 103, for example, it sends a correct signal. Upon receiving the correct signal, the control unit 106 activates the counting sensor 105. When the control unit 106 receives a color mismatch signal from the color sensor 104, it records the error type as "color error" and skips the activation of the counting sensor 105.

[0039] When the counting sensor 105 is activated and detects that the bead 102 has passed through and outputs a counting signal, the control unit 106 increments the counter by 1 and generates a single operation success signal. The control unit 106 then performs preliminary sorting and packaging of the relevant information of this operation (such as operation time, bead 102 color, bead box 103 color, operation result, and clamping time).

[0040] In a specific embodiment of this first implementation, the bead 102 has a smooth surface and reflective properties, and the inside of the bead box 103 is coated with a reflective coating. Specifically, the bead 102 can be a spherical particle with a diameter of 5-6 mm, made of medical-grade plastic, with a smooth surface and reflective properties to improve the detection accuracy of the color sensor 104. The inner wall of the bead box 103 is coated with a reflective coating with a reflectivity ≥90% to enhance the signal acquisition effect of the color sensor 104.

[0041] In a specific embodiment of this implementation method one, such as Figure 3 As shown, the top of the bead box 103 is provided with a trumpet-shaped bead guide opening, the diameter of which gradually decreases from the inlet end to the outlet end. The interior of the bead box 103 has a cone-like design, which facilitates the sliding of the beads 102 to the bottom of the bead box 103. The bottom of the bead box 103 can be provided with a through hole to connect with the receiving box 101 for easy recycling.

[0042] In a specific embodiment of this first implementation, the color sensor 104 is positioned above the counting sensor 105, so that the inserted bead 102 passes through the color sensor 104 first and then through the counting sensor 105. After the bead 102 passes through the color sensor 104, the color sensor 104 transmits a judgment signal to the control unit 106. The control unit 106 controls the counting of the counting sensor 105 based on the signal transmitted by the color sensor 104. The counting sensor 105 will only start counting when the color sensor 104 determines that the color of the bead 102 matches the color of the bead box 103; otherwise, it will not count.

[0043] Specifically, the color sensor 104 can be a spectral color sensor 104, used to collect the color value of the bead 102 and compare it with a preset color threshold to determine whether the color of the bead 102 is consistent. When the bead 102 is put into the bead box 103, ambient light shines on the surface of the bead 102. The bead 102 absorbs and reflects light of different wavelengths. The spectral characteristics of the reflected light depend on the color attributes of the bead 102 itself. The spectral color sensor 104 installed inside the bead box 103 can sense the light reflected back from the bead 102 and convert it into an electrical signal. During the initialization of the bead-throwing training device, a corresponding color threshold is preset for each bead box 103. When the spectral sensor senses the color data of the bead 102, it compares it with the preset color threshold to determine whether the colors are consistent.

[0044] Specifically, the counting sensor 105 is located on the side wall of the bead box 103, maintaining a certain preset distance from the bottom of the bead box 103. This preset distance ensures that the bead 102 is fully inside the bead box 103 for a certain distance before triggering the count. This prevents the bead 102 from being miscounted as soon as it enters the opening of the bead box 103, before passing the color sensor 104, or when it has fully fallen in, or from being missed due to shaking at the opening or not being stably inserted. It ensures that only beads 102 that have fully entered the bead box 103 and meet the requirements are counted, improving counting accuracy. If the counting sensor 105 were installed at the bottom of the bead box 103, the vibration and rebound caused by the bead 102 hitting the bottom could easily interfere with the sensor, leading to misjudgments. Installing it at a certain distance from the side wall effectively avoids interference from vibration and rebound caused by the bead 102 hitting the bottom, ensuring that the counting sensor 105 only responds to signals indicating that the bead 102 has passed normally, guaranteeing counting reliability.

[0045] Optionally, the counting sensor 105 is a through-beam infrared sensor, which includes a transmitter and a receiver. The transmitter and receiver are respectively disposed inside the sidewalls opposite to the bead-feeding opening, and are used to detect whether the bead 102 has passed through and to count it. When the bead 102 passes through a specific position in the bead-feeding box 103, it will block the infrared light emitted by the transmitter. Due to the obstruction of the bead 102, the infrared light cannot reach the receiver normally, causing the intensity of the infrared light received by the receiver to decrease sharply or even disappear. After detecting this change in the infrared light signal, the receiver converts it into a corresponding change in electrical signal, triggering the counting.

[0046] In this embodiment, the bead-throwing training device also includes a data recording and analysis unit 107, which processes the signals acquired from the color sensor 104 and the counting sensor 105 and generates training data.

[0047] As mentioned earlier, the control unit 106 initially organizes and packages the relevant information of this operation (such as operation time, bead 102 color, bead box 103 color, operation result, and retrieval time). The control unit 106 transmits the organized relevant information to the data recording and analysis unit 107 for in-depth processing and analysis, generating training data. The training data includes, for example, calculating the total number of operations, accuracy rate, average retrieval time, color misjudgment rate, and drop rate, generating visual charts such as the operation speed-accuracy fitting curve, and predicting the trainee's skill improvement curve based on historical training data. The bead-throwing trainer of this embodiment is not only suitable for daily surgical skills training, but also for systematic examinations. Through a preset assessment scheme, the system can automatically complete the operation data statistics and scoring, directly output the examination score, ensure the objectivity and fairness of the assessment results, greatly improve the assessment efficiency and standardization, and effectively fill the technical gap in the field of precise quantitative assessment and intelligent assessment of existing surgical trainers.

[0048] In this embodiment, the bead-throwing training device also includes a display unit 108, which is used to display training data in real time. The data recording and analysis unit 107 transmits data to the display unit 108, which can display the training data in real time for the trainee to view.

[0049] The bead-throwing training device of this embodiment, through the coordinated work of the control unit, data recording and analysis unit, color sensor and counting sensor, realizes a complete workflow from bead detection, operation result judgment to data recording and analysis and information feedback, providing accurate and comprehensive data support for the training and evaluation of laparoscopic surgical operation skills.

[0050] Please see Figure 4The second embodiment of this application also provides a laparoscopic surgery training device 21, which includes a surgical simulation box 221 and a bead-throwing trainer located inside the surgical simulation box. The bead-throwing trainer is placed inside the surgical simulation box 221, which has a plurality of insertion holes 2211. Surgical instruments such as long-handled clamps are inserted into the surgical simulation box 221 through the insertion holes 2211, and the bead-throwing trainer is trained to throw beads under the display of an imaging device.

[0051] The bead-throwing training device can be any of the bead-throwing training devices described in the above embodiments, and will not be described in detail here.

[0052] The laparoscopic surgery training device of this embodiment integrates the bead-throwing trainer into the surgical simulation box, which can simulate the real laparoscopic operation environment. It is suitable for surgical skills training and standardized assessment, and solves the problems of insufficient quantitative assessment and missing data recording of existing equipment, significantly improving training efficiency and assessment accuracy.
