Abstract
Description
Technical Field
[0001] This invention relates to the field of simulation training equipment technology, and specifically to a box-type support laryngoscope surgical simulation training equipment. Background Technology
[0002] Over the past 20 years, the public's demands for medical safety have been increasing, creating a contradiction between the development of surgeons and patient safety. Voice microsurgery is a combination of microsurgery and endoscopic laryngology, requiring a high level of surgical skill. The pharynx and larynx are located deep within the body, with intricate anatomy and complex vocal physiology. Furthermore, the vocal cords are delicate and fragile, the surgical space is narrow, and the surgical path is long and narrow. Removing lesions while preserving or reconstructing normal voice function as much as possible places high demands on the technical skills of voice surgeons.
[0003] The traditional surgical learning model involves junior surgeons practicing actual cases in the operating room under the guidance of senior physicians. Through the accumulation of cases, their surgical skills improve. However, this model is lengthy and extremely expensive. Furthermore, patients and society pay a heavy price for the early immaturity of the surgeons. Senior physicians, for medical safety reasons, cannot completely relinquish control. Besides video observation, beginners rarely have hands-on experience with live surgical procedures, significantly prolonging the time it takes for young surgeons to mature. Therefore, developing an effective, rational, and progressively advanced surgical simulation training system would be immensely beneficial, both socially and economically. However, currently, there is no standardized and regulated laryngeal microsurgery training system to address this issue.
[0004] In existing literature, patent CN210244806U discloses a laryngeal microsurgery simulation training device, which includes a laryngeal body fixation module for fixing an isolated (pig) laryngeal specimen and a laryngoscope fixation module for fixing a laryngoscope. This training simulator uses animal (pig) laryngeal specimens (available in bulk on the market and readily accessible) and professional microsurgical equipment to simulate the surgical environment. It offers high fidelity, allowing operators to observe the vocal cords using a microscope and a supporting laryngoscope, and to perform simulated surgeries using real surgical instruments or CO2 lasers. This enables simulated operations such as submucosal injection, micro-flap creation, vocal cord lesion treatment, microsurgical suturing, and CO2 laser surgery within a real biological pharyngeal structure. This effectively improves beginners' comprehensive proficiency in minimally invasive pharyngeal surgery, shortens the learning curve, boosts the confidence of young doctors, and enhances medical quality and safety. However, it has the following problems: On the one hand, the training simulator component is relatively sophisticated and has a high degree of simulation and reproduction of real surgical scenarios. Moreover, the technology has not yet been commercialized or mass-produced. In particular, products with high requirements for detail are difficult to imitate. At present, most institutions can only use the training simulator for training by participating in training courses. On the other hand, the training of this system requires the consumption of animal larynx specimens, and the simulator has high requirements for maintenance and cleaning. Summary of the Invention
[0005] To overcome the shortcomings of existing technologies, this invention provides a box-type support laryngoscope surgical simulator, which solves the aforementioned traditional problems. It is simpler, suitable for basic skills training, and uses other simulated objects (rather than animal specimens) as carriers for practice. It can be used for training at any time during spare time and is easy to promote.
[0006] This invention is achieved using the following technical solution:
[0007] A box-type support laryngoscope surgical simulator includes a box and a laryngeal body simulation training module installed in the box. The front of the box has an instrument operation port, and the angle between the instrument operation port and the laryngeal body simulation training module is an acute angle. The laryngeal body simulation training module includes a perforated ring and an inverted V-shaped adhesive strip, with the adhesive strip located on the rear side of the ring.
[0008] Preferably, the angle between the instrument operating port and the laryngeal body simulation training module is 20°-50°.
[0009] Preferably, the angle between the instrument operating port and the laryngeal body simulation training module is 30°-45°.
[0010] Preferably, the box is a transparent, open cubic box without a top cover, and the distance between the upper edge of the instrument operating port and the upper end of the box is 1 / 3 to 1 / 2 of the distance between the lower edge of the instrument operating port and the lower end of the box.
[0011] Preferably, the box body has the following specifications: the bottom surface is a square with a width of 20cm and a height of 15cm; all sides of the box body are made of transparent acrylic sheets with a thickness of 8mm; and the instrument operating port has the following specifications: length of 4cm and width of 2cm.
[0012] Preferably, the ring is a detachable structure.
[0013] Preferably, the inverted V-shaped adhesive strip is an inverted V-shaped brown silicone strip.
[0014] Preferably, the inverted V-shaped adhesive strip has a central gap with the inner wall of the box, and the size of the central gap is 0.4cm-0.6cm.
[0015] Preferably, the inverted V-shaped adhesive strip has the following specifications: 3cm in length and 1cm in width.
[0016] Preferably, the housing is further provided with a simulated glottis vent located at the rear end of the inverted V-shaped rubber strip, and the diameter of the simulated glottis vent is 1.5cm-2.5cm.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0018] The box-type support laryngoscope surgical simulator of the present invention combines a box and a laryngeal body simulation training module. An instrument operation port is provided on the box. Surgical instruments are inserted through the instrument operation port and reach the operation area of the laryngeal body simulation training module inside the box to perform corresponding laryngoscope surgical simulation operations. This forms a simplified simulation, making the simulation operation simpler and suitable for basic skills training. It can also use other simulated objects (rather than animal specimens) as carriers for practice, and can be trained at any time during spare time at work, making it easy to promote.
[0019] The box-type laryngoscopy simulation trainer of this invention, compared to traditional real laryngoscopy surgery, can serve as a basic, simplified simulation trainer for junior physicians or otolaryngologists to complete entry-level training, shortening the learning curve for laryngoscopy surgery. It allows for training during spare moments, and is significantly easier than simulated operations or actual surgery. Repeated practice helps develop a feel for the procedure and motor memory unconsciously. From a tiered, progressive training perspective, modern skills training typically includes virtual, simulation, and hands-on training. This invention's simulation trainer falls under the simulation training component. Traditional simulation trainers (i.e., patent CN210244806U) lean more towards simulation training; the former lays the foundation for the latter, which is suitable for otolaryngologists with existing microsurgical laryngoscopy skills. For interns and junior otolaryngologists, however, only a basic understanding and familiarization with microsurgical laryngoscopy is needed to cultivate interest in learning and practicing the procedure.

[0025] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] In the description of this invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0027] In the description of this invention, it should be understood that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be intermediate elements present. Conversely, when an element is referred to as being "directly" connected to another element, there are no intermediate elements.
[0028] Please see Figures 1-2 This invention relates to a preferred embodiment of a box-type support laryngoscope surgical simulator, which is used for laryngoscopic surgical simulation training by interns and junior ENT physicians. Specifically, the box-type support laryngoscope surgical simulator includes a box body 10 and a laryngeal body simulation training module 20 installed inside the box body 10. The front of the box body 10 has an instrument operation port 11, and the angle between the instrument operation port 11 and the laryngeal body simulation training module 20 is an acute angle. The laryngeal body simulation training module 20 includes a perforated ring 21 and an inverted V-shaped adhesive strip 22, with the adhesive strip 22 located behind the ring 21.
[0029] Understandably, the instrument operating port 11 is a simplified simulation of the laryngoscope operating approach. A perforated ring 21 is fixed to the inner wall of the housing 10 via a retainer. This ring 21 is designed for training basic microsurgical knot-tying skills. During training, the trainee ties knots on the ring 21 using surgical instruments. The amplitude and frequency of the ring 21's swinging displacement during knot-tying indirectly reflect the trainee's stability in handling the instrument. Changing to different sizes of rings 21 can increase or decrease the knot-tying difficulty accordingly. For example, changing from a large ring 21 to a small ring 21 increases the knot-tying difficulty and correspondingly increases the requirement for instrument operation stability. In this embodiment, the ring 21 is a conventional key ring design with a detachable structure, allowing for the replacement of rings 21 of different sizes. The inverted V-shaped adhesive strip 22 is a simulated vocal cord. This part is a visual simulation of the vocal cords and glottis, used for stitching during simulation training. The silicone strip 22 used for the simulated vocal cords is made from commercially available door sealant, which is readily available and can be cut to the desired length. It is fixed with double-sided adhesive and is easy to remove and replace. The adhesive strip 22 is also fixed to the inner wall of the enclosure 10 using a fastener.
[0030] The aforementioned box-type support laryngoscope surgical simulator combines a box body 10 and a laryngeal body simulation training module 20. An instrument operation port 11 is provided on the box body 10. Surgical instruments are inserted through the instrument operation port 11 and reach the operation area of the laryngeal body simulation training module 20 inside the box to perform corresponding laryngoscope surgical simulation operations. This forms a simplified simulation, making the simulation operation simpler and suitable for basic skills training. It can also use other simulated objects (rather than animal specimens) as carriers for practice, allowing for training at any time during spare moments and making it easy to promote.
[0031] like Figure 1 As shown, the box 10 is a transparent, open-top cubic box with a 20cm wide square base and a height of 15cm. All sides of the box 10 are made of 8mm thick transparent acrylic panels, providing excellent light transmission. The choice of material and size for the box ensures visualization during operation. The entire system weighs only 800g, ensuring high stability, preventing shaking, and making it easy to move and carry. Furthermore, because the box 10 is open-top, the operator can directly observe the surgical simulation training from the top, eliminating the need for a microscope. The components are easily assembled, with no obstructions to the operating space, and minimal requirements for external factors such as the operating table and chair. In another embodiment, the front of the box 10 or the operating part of the instrument operating port 11 is covered with blocking paper. That is, except for the instrument operating port 11, the rest is blocked by blocking paper, making it opaque. This also restricts the operator's view from the top of the box 10, allowing them to only view through the instrument operating port 11, thus increasing the difficulty of the operation and further assessing the operator's surgical skill. In other embodiments, the choice of the box body material and size can be customized according to specific needs, which will not be elaborated here. Optionally, the instrument operating port 11 is a small rectangular perforated opening in the upper half of the front center of the box 10. Specifically, the distance between the upper edge of the instrument operating port 11 and the upper end of the box 10 is 1 / 3 to 1 / 2 of the distance between the lower edge of the instrument operating port 11 and the lower end of the box 10. In this embodiment, as... Figure 3 As shown, the box 10 has a width of 20cm (18.4cm after deducting the thickness) and a height of 15cm (14.2cm after deducting the thickness). The distance A1 between the upper edge of the instrument operating port 11 and the upper end of the box 10 is 4cm. The distance A2 between the lower edge of the instrument operating port 11 and the lower end of the box 10 is 8.2cm (after deducting the thickness). The distances on both sides of the instrument operating port 11 are equal to the distances on both sides of the box 10, i.e., A3 = A4 = 8cm (7.2cm after deducting the thickness). Specifically, the dimensions of the instrument operating port 11 are: 4cm long and 2cm wide. In some other embodiments, the size of the instrument operating port 11 can be adjusted as needed, which will not be elaborated here.
[0032] like Figure 2 As shown, the angle formed between the instrument operation port 11 and the laryngeal simulation training module 20 is 20°-50°. Specifically, angle a between the ring 21 and the instrument operation port 11 is 20°-50°, and angle b between the adhesive strip 22 and the instrument operation port 11 is 20°-50°, depending on the specific operating route of the surgical instruments and the laryngeal simulation training module 20. In this embodiment, the angle formed between the instrument operation port 11 and the laryngeal simulation training module 20 is 30°-45°. In this invention, the position of the instrument operation port 11 and its relative position to the inner wall ring 21 and the adhesive strip 22 simulating the vocal cords are designed after fully referencing real surgical operations. This ensures that the training operation route forms a 30-45° angle with the horizontal plane, conforming to real-world scenarios and ergonomic characteristics. Secondly, the distance from the instrument entry window to the operating area is approximately 20cm, which is the same as the length of a conventional laryngoscope. This allows operators to be trained through layered and progressive simulations, making it easier for them to become proficient in real laryngoscope surgery procedures later on.
[0033] For example Figure 4 As shown, the circular ring 21 is attached to the lower half of the inner wall of the housing 10 via a fastener such as a suction cup, making it detachable from the housing 10 and allowing for replacement with rings of different sizes as needed. The inverted V-shaped adhesive strip 22 is attached to the lower quarter of the inner surface of the housing 10. It is an inverted V-shaped brown silicone strip 22. The use of a colored adhesive strip 22, specifically brown, improves the operator's recognition and the similarity of the simulation. In this embodiment, there is a central gap between the inverted V-shaped adhesive strip 22 and the inner wall of the housing 10, with a gap size of 0.4cm-0.6cm. This part is a visual simulation of the vocal cords and glottis. The hollow design provides space for the needle to enter and exit during sewing operations, and the "force feedback" feel of the needle on the silicone strip 22 material is similar to that of a real vocal cord. Specifically, the specifications of the inverted V-shaped adhesive strip 22 are: 3cm long, 1cm wide, and a central gap size of 0.5cm. In another embodiment, the housing 10 is also provided with a simulated glottis vent 23 located at the rear end of the inverted V-shaped adhesive strip 22, which simulates a glottis leading to a trachea. The diameter of the simulated glottis vent 23 is 1.5cm-2.5cm, such as 1.5cm, 1.8cm, 2.0cm, 2.2cm, 2.5cm, etc.
[0034] The entire system of the aforementioned box-type laryngoscopy simulation trainer weighs 800g. The main material is a transparent acrylic sheet, offering good light transmission and easy cleaning. This design allows for flexible movement while ensuring a certain level of support stability, preventing displacement during operation. Compared to actual laryngoscopy, this invention can serve as a basic, simplified simulation trainer for junior physicians or laryngoscopy professionals to complete entry-level training, shortening the learning curve for laryngoscopy. The training medium is no longer an animal laryngeal specimen, but rather non-living materials (metal rings 21, silicone strips 22). Basic operations such as knot tying and suturing can be practiced. Raw materials are readily available, easy to replace, and easy to clean.
[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0036] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
