Utility Model Content

[0029] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. 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.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0031] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The surgical training threading module of the first embodiment of this application includes:

[0032] A base 11 is provided with at least one column 12; a wire-passing hole 13 is opened on the column 12, and the wire-passing hole 13 passes through both ends of the column 12; a photoelectric sensor group 14 is arranged circumferentially along the inner wall of the wire-passing hole 13 for detecting whether the wire passes through the wire-passing hole 13; a signal processing module 15 is connected to the photoelectric sensor group 14; a feedback device 16 is connected to the signal processing module 15; when the photoelectric sensor group 14 detects that the wire has passed completely through the wire-passing hole 13, the signal processing module 15 triggers the feedback device 16 to output a wire-passing success signal.

[0033] Specifically, the column 12 is fixedly or movably connected to the base 11. Generally, the column 12 is vertically arranged on the base 11, but in other embodiments, it can also be arranged at a certain angle on the base 11.

[0034] During surgical training, the surgeon uses long-handled clamps to pick up the suture and move it to the suture hole 13 on the column 12, then passes the suture through the hole 13. The surgeon can alternate between their left and right hands, thereby training their left- and right-hand coordination and spatial orientation. This surgical training scenario can be used, for example, for laparoscopic surgery training, increasing the surgeon's proficiency in manipulating instruments during actual laparoscopic minimally invasive surgery.

[0035] The photoelectric sensor group 14 is axially arranged on the inner wall of the wire hole 13. When the wire passes through the wire hole 13, a sensing signal is triggered and transmitted to the signal processing module 15. The signal processing module 15 has a preset condition for judging whether the wire has successfully passed through the wire hole 13. By comparison, the conclusion is drawn as to whether the wire has successfully passed through the wire hole 13.

[0036] Feedback device 16 can acquire the conclusion information from signal processing module 15 and provide corresponding prompts based on the conclusion information. Optionally, feedback device 16 is an indicator light, such as an LED indicator, where a green light indicates success and a red light indicates failure. Optionally, feedback device 16 is a buzzer, which determines success based on sound frequency. Optionally, feedback device is a voice broadcasting device, which determines success based on sound broadcasting.

[0037] In a specific application scenario of this embodiment, the photoelectric sensor group 14 includes infrared through-beam sensors symmetrically arranged at the inlet end 131 and the outlet end 132 of the wire hole 13. Specifically, the photoelectric sensor group 14 is composed of two pairs of infrared through-beam sensors, which are respectively embedded in the inlet end 131 and the outlet end 132 of the wire hole 13. Each pair of infrared through-beam sensors includes a transmitting unit 141 and a receiving unit 142.

[0038] The transmitting unit 141 and the receiving unit 142 are respectively embedded in the symmetrically formed annular grooves on the inner wall of the threading hole 13. The opening of the groove can be covered with a transparent protective layer of a certain thickness to prevent interference. The optical axes of the transmitting unit 141 and the receiving unit 142 form an angle of 0-15° with the axis of the threading hole, so that the changes in infrared light can be better sensed during the threading process.

[0039] Optionally, the transmitting unit 141 uses a narrow-beam infrared LED with a wavelength of 850nm to emit light signals in the direction of the axis of the wire hole 13 with a divergence angle of 30°; the receiving unit 142 is configured as a phototransistor array matched with the transmitting unit 141, with the center of the receiving surface aligned with the optical axis of the transmitting unit 141.

[0040] When the thread passes through the threading hole 13, it sequentially blocks the infrared beams at the entrance end 131 and the exit end 132, triggering a sensor signal transition. The signal processing module 15 receives the sensor signal. The signal processing module 15 has preset conditions for successful threading, such as when the trigger time difference between the infrared beam sensors located at the entrance end 131 and the exit end 132 is less than a preset threshold, it is determined that the threading is successful. The signal processing module 15 can also further process the sensor signal to obtain parameters such as the trainee's threading success rate and threading speed, so that they can be transmitted in real time to an external display terminal for further data processing and analysis via the data transmission module.

[0041] In this way, the threading module of this embodiment can automatically obtain feedback on whether the threading is successful when the trainee performs the threading operation. The trainee can also obtain threading success rate and threading speed parameters, thereby making the training process more intelligent and precise.

[0042] In this embodiment, optionally, the outer diameter of the column 12 can be different, and the shape of the outer periphery of the column 12 can be circular, rhomboid, square, etc. The outer periphery of the column 12 can be provided with threads, grooves, protrusions, etc. Optionally, the height of the column 12 can be adjusted, for example, by setting a multi-section telescopic column; wire holes can be set on columns of different specifications and sizes, and the extension path of the wire holes will also be different. One wire hole or multiple wire holes can be set on the column. The wire holes can pass through the column vertically, or wire holes 13 with different inclination angles can be set. The trainee can only successfully thread the wire when following the preset angle and path, which greatly increases the scalability and flexibility of the training.

[0043] In this embodiment, the threading module also includes a storage box 17, in which pre-prepared threads are placed for easy access during surgical training.

[0044] In this embodiment, the threading module also includes a data transmission module for transmitting training data to an external display terminal in real time, where it is aggregated, displayed, and processed. The external display terminal can record the learning curves of each trainee and the learning curves of different departments for further comprehensive evaluation.

[0045] Please see Figure 4 The second embodiment of this application also provides a surgical simulation device 21, which includes a surgical simulation box 221 and a threading module located inside the surgical simulation box. The threading module 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. Under the display of an imaging device, the threading module is trained to thread sutures.

[0046] The threading module can be the threading module in the first embodiment described above, and will not be described in detail here.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
