Description

Technical Field

[0001] This invention relates to the field of medical surgical training equipment technology, and in particular to a thoracoscopic minimally invasive surgery training device that simulates the structure of human chest organs and tissues. Background Technology

[0002] Thoracoscopic minimally invasive surgery, with its advantages of minimal trauma and rapid recovery, has been widely used in the fields of thoracic and cardiothoracic surgery, including pulmonary surgery, esophageal surgery, mediastinal surgery, and thoracic disease surgery. It is also developing towards a more minimally invasive and precise direction. However, the development and popularization of thoracoscopic minimally invasive surgery technology faces many challenges. At present, most county and city-level hospitals lack thoracic surgeons with the skills to perform thoracoscopic minimally invasive surgery and are unable to carry out such surgeries. In-depth analysis shows that the long learning curve and growth curve of thoracoscopic minimally invasive surgeons are important limiting factors. The key to this phenomenon lies in the lack of clinical surgical practice experience and effective simulated surgical training.

[0003] Existing thoracoscopic surgery training models have many shortcomings. Most are simply plastic boxes with a few pre-drilled holes and equipped with toy-level forceps, scissors, and low-resolution cameras, only capable of simple operations such as picking up beans, suturing, and cutting paper. Training on these models results in significant differences and distortions compared to actual clinical surgery in areas such as surgical positioning, incision, organ and tissue spatial structure layout, surgical field of view, tissue resolution, surgical angles, and instrument handling feel. This makes it either tedious and difficult for beginners to persevere, or leads to a lack of confidence and confusion in actual surgical procedures due to the large differences from real surgery, or even surgical errors due to the different surgical feel, seriously hindering the development and popularization of minimally invasive thoracoscopic surgery. Summary of the Invention

[0004] To overcome existing problems, this application provides a thoracoscopic minimally invasive surgery training device that simulates the structure of human chest organs and tissues. By highly simulating the structure of human chest organs and tissues and real surgical scenarios, it provides an effective simulation training platform for thoracoscopic minimally invasive surgeons, enhancing their minimally invasive surgical sense, clinical surgical skills and confidence, shortening the learning curve and growth curve, rapidly improving their minimally invasive surgical skills, reducing thoracoscopic minimally invasive surgery complications, significantly reducing training and learning costs, and promoting the development, popularization and application of thoracoscopic minimally invasive surgery.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A thoracoscopic minimally invasive surgery training device that simulates the structure of human chest organs and tissues includes a chest cavity module. One end of the chest cavity module is provided with a head module. A connector is provided at the intersection of the head module and the chest cavity module. The connector is a detachable structure, which facilitates the assembly and disassembly of the various modules of the training device. The other end of the chest cavity module is provided with a lower limb module.

[0007] The lower limb module includes hip and knee joints, both of which allow flexion and extension to simulate normal surgical positioning. The thoracic module has upper limb modules on both sides, each including shoulder and elbow joints, also allowing flexion and extension to simulate normal surgical positioning. The flexibility of the elbow, shoulder, hip, and knee joints simulates normal surgical positioning, making training more closely resemble actual surgical scenarios. Simulating real-life surgical procedures on these simulators enhances the sense of minimally invasive surgery, clinical surgical skills, and confidence, significantly shortening the learning curve and growth curve, rapidly improving minimally invasive surgical skills, reducing complications in thoracoscopic minimally invasive surgery, greatly reducing training costs, and promoting the development, popularization, and application of thoracoscopic minimally invasive surgery.

[0008] Preferably, the back of the thoracic module is provided with a spinal joint, which has the function and range of bending to simulate the left and right sides of the human body in order to simulate the normal surgical position. The spinal joint has the function and range of bending to simulate the left and right sides of the human body in order to further meet the needs of surgical position simulation.

[0009] Preferably, the thoracic cavity module includes skin tissue, subcutaneous tissue, muscle tissue, rib tissue, bone tissue, and thoracic organ tissue. The skin tissue, subcutaneous tissue, muscle tissue, rib tissue, bone tissue, and thoracic organ tissue simulate the anatomical layers and structural layout of the normal human chest, and are used to simulate minimally invasive thoracic surgery training, providing a basis for various operational training in thoracoscopic minimally invasive surgery.

[0010] Preferably, the simulated human organs and tissues within the thoracic cavity module are modularly combined and installed. Their assembly, arrangement, and spatial layout completely simulate the normal thoracic organ structure and tissue layout. The modular assembly method facilitates disassembly, replacement, and maintenance, and allows for flexible adjustments according to different training needs.

[0011] Preferably, the thoracic cavity module component is made of a material that simulates the shape, color, texture, elasticity, and semi-transparent micro-elasticity of the corresponding organs and tissues in the human chest. This makes the training operation similar to touch, highly visual and easy to visualize, which can enhance the real feeling of surgery, provide teaching guidance and assess the proficiency of operation, and allow beginners to observe the surgical operation process and organ and tissue structure more clearly.

[0012] Preferably, the simulated human organ tissue components within the thoracic cavity module have high durability, allowing for multiple clamping, pushing, traction, and suturing operations without easily breaking. They can withstand a large number of training operations, extending the lifespan of the trainer and reducing usage costs. The surfaces of the simulated human organ tissue components within the thoracic cavity module have micro-adhesion, and the loose connective tissue connections between the simulated organs are used to simulate surgical operations in the interstitial spaces of free organs in actual clinical anatomy. This facilitates the simulation of actual clinical surgical operations, making the training operations closer to the real surgical experience and improving training effectiveness.

[0013] Preferably, the thoracic cavity module can be equipped with simulated diseased tissue or animal organ tissue with the same anatomical name, such as the right lung of a pig being embedded in the position of the right lung of a human, to simulate the lesion treatment operation in thoracoscopic minimally invasive surgery. The spatial structure and pre-made surgical incision path of the thoracic cavity module are matched with the incision path of clinical thoracoscopic surgery.

[0014] The advantages of the embodiments of this application are:

[0015] 1. It can highly simulate the structure of human chest organs and tissues and real surgical scenarios. Users can perform simulated real surgical operations on this trainer. Through repeated training, it can effectively enhance the feeling of minimally invasive surgery and improve the clinical surgical operation ability. Because the training process is close to real surgery, users accumulate experience in training and gradually overcome their fear and lack of confidence in actual surgery, so that they can operate more calmly and confidently in actual surgery.

[0016] 2. Compared with traditional training devices, this invention provides a more realistic and effective training environment, which can help thoracoscopic minimally invasive surgeons quickly master surgical skills, greatly shorten the learning curve and growth curve, improve learning and growth efficiency, and through sufficient training on this training device, doctors can master surgical operations proficiently, shorten the time and salary costs of further study, reduce surgical errors caused by lack of operation skills, thereby reducing the probability of complications in thoracoscopic minimally invasive surgery and reducing the risk and cost of medical accidents.

[0026] This application provides a thoracoscopic minimally invasive surgery training device that simulates the structure of human chest organs and tissues, solving the problems in the prior art. It can highly simulate the structure of human chest organs and tissues and real surgical scenarios. Users can perform simulated surgical operations on this training device. Through repeated training, they can effectively enhance their sense of minimally invasive surgery and rapidly improve their clinical surgical skills.

[0027] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0028] Example 1

[0029] This embodiment provides the specific structure of a thoracoscopic minimally invasive surgery training device that simulates the structure of human chest organs and tissues, such as... Figure 1-5 As shown, it includes a chest cavity module 3, a head module 1 at one end of the chest cavity module 3, a connector 7 at the intersection of the head module 1 and the chest cavity module 3, the connector 7 is a detachable structure, which facilitates the assembly and disassembly of each module of the trainer, and a lower limb module 6 at the other end of the chest cavity module 3.

[0030] The lower limb module 6 includes a hip joint 4 and a knee joint 5, both of which allow flexion and extension to simulate normal surgical positioning. The thoracic module 3 has upper limb modules 2 on both sides, including a shoulder joint 8 and an elbow joint 9. Both shoulder and elbow joints allow flexion and extension to simulate normal surgical positioning. The elbow joint 9, shoulder joint 8, hip joint 4, and knee joint 5 allow flexion and extension, simulating normal surgical positioning, making training more closely resemble actual surgical scenarios. Simulating real-life surgical procedures on these simulators enhances the sense of minimally invasive surgery, clinical surgical skills, and confidence, significantly shortening the learning curve and growth curve, rapidly improving minimally invasive surgical skills, reducing complications in thoracoscopic minimally invasive surgery, greatly reducing training costs, and promoting the widespread application and development of thoracoscopic minimally invasive surgery.

[0031] The back of the thoracic module 3 is equipped with a spinal joint 10. The spinal joint 10 has the function and range of bending to simulate the left and right sides of the human body in order to simulate the normal surgical position. The spinal joint 10 has the function and range of bending to simulate the left and right sides of the human body in order to further meet the needs of surgical position simulation.

[0032] The thoracic module 3 includes skin tissue 31, subcutaneous tissue 32, muscle tissue 33, rib tissue 34, bone tissue 35, and thoracic organ tissue 36. The simulated components of skin tissue 31, subcutaneous tissue 32, muscle tissue 33, rib tissue 34, bone tissue 35, and thoracic organ tissue 36 are arranged to simulate the anatomical layers and structural layout of the normal human chest. It is used to simulate minimally invasive chest surgery training and provides a foundation for various operational training in thoracoscopic minimally invasive surgery.

[0033] The simulated human organs and tissues within the thoracic cavity module 3 are modularly assembled and installed. Their assembly, arrangement, and spatial layout completely simulate the normal chest organ structure and tissue layout. This modular assembly method facilitates disassembly, replacement, and maintenance, and allows for flexible adjustments based on different training needs.

[0034] The thoracic module 3 uses a semi-transparent micro-elastic material that simulates the shape, color, texture, elasticity, and other characteristics of the corresponding organs and tissues in the human chest. This makes the training operation similar to tactile sensation, highly visual and perceptible, and easy to enhance the realism of the surgery, teaching guidance, and assessment of operational proficiency. It allows beginners to observe the surgical operation process and organ and tissue structure more clearly.

[0035] The simulated human organs and tissues within the thoracic module 3 have high durability, allowing for multiple clamping, pushing, traction, and suturing operations without easily breaking. They can withstand a large number of training operations, extending the lifespan of the trainer and reducing usage costs. The surfaces of the simulated human organs and tissues within the thoracic module 3 have a slight adhesiveness, and the loose connective tissue connections between the simulated organs are used to simulate surgical operations in the interstitial spaces of free organs in actual clinical anatomy. This facilitates the simulation of actual clinical surgical operations, making the training operations closer to the real surgical experience and improving training effectiveness.

[0036] The thoracic module 3 can be fitted with simulated diseased tissue or animal organ tissue with the same anatomical name, such as the right lung of a pig, which is used to simulate the lesion treatment operation in thoracoscopic minimally invasive surgery. The spatial structure and pre-made surgical incision path of the thoracic module 3 are matched with the incision path of clinical thoracoscopic surgery.

[0037] By adopting the above technical solution:

[0038] Place the assembled simulator on a standard surgical training table, adjust the spinal joint 10 to bend to the left, the shoulder joint 8 to abduct, and the elbow joint 9 to flex, simulating the right lateral decubitus surgical position. Install the lung simulation component in the right side of the chest cavity module 3 to simulate the chest cavity, simulating common lung surgery locations, and embed simulated lesion tissue, such as block-shaped components simulating lung tumors, into the lung simulation component.

[0039] Trainees can choose modular training in stages. First, they will practice chest wall tissue incision, using a scalpel to sequentially incise simulated components: skin (31), subcutaneous tissue (32), muscle tissue (33), rib tissue (34), bone tissue (35), and thoracic organ tissue (36). During this process, they will experience the differences in texture and cutting resistance among different tissue layers. After completing the incision, they will use a needle holder and sutures to suture the simulated incisions, practicing the location, selection, incision, and closure of incision sites for minimally invasive surgery on different organs and tissues in the chest. Next, they will choose to enter the thoracic cavity through incisions at different locations on the chest wall. Thoracoscopic observation of lesions in different locations of the thoracic cavity; training the thoracoscopic operator in adjusting and using the surgical field of view (up, down, left, right, deep, shallow, advance, retreat), focal length, fiber optic angle, etc.; how to better observe, expose, and stabilize the surgical field of view; radiography; video recording; fluorescence; light intensity; mode switching, etc. of thoracoscopy; then, selecting incisions at different locations, operating minimally invasive surgical instruments to perform operations such as traction, pushing, blocking, picking, prying, exposing, dissecting, separating, cutting, suturing, hemostasis, and resection of lesions in different locations; simulating the surgical treatment process of thoracic organ tissue lesions; training the operator in instrument control and the management of the surgical field of view in a simulated thoracoscopic minimally invasive surgical environment.

[0040] After the training, the supervising physician will evaluate the trainees' standardization of movements, proficiency, suturing quality, and treatment of simulated lesions during the operation. Using the visualization features of the training device, the supervising physician will point out problems in the operation and provide targeted improvement suggestions.

[0041] Example 2

[0042] This embodiment provides the specific structure of a thoracoscopic minimally invasive surgery training device that simulates the structure of human chest organs and tissues, such as... Figure 1-5 As shown, it includes a chest cavity module 3, a head module 1 at one end of the chest cavity module 3, a connector 7 at the intersection of the head module 1 and the chest cavity module 3, the connector 7 is a detachable structure, which facilitates the assembly and disassembly of each module of the trainer, and a lower limb module 6 at the other end of the chest cavity module 3.

[0043] The lower limb module 6 includes a hip joint 4 and a knee joint 5, both of which allow flexion and extension to simulate normal surgical positioning. The thoracic module 3 has upper limb modules 2 on both sides, including a shoulder joint 8 and an elbow joint 9. Both shoulder and elbow joints allow flexion and extension to simulate normal surgical positioning. The elbow joint 9, shoulder joint 8, hip joint 4, and knee joint 5 allow flexion and extension, simulating normal surgical positioning, making training more closely resemble actual surgical scenarios. Simulating real-life surgical procedures on these simulators enhances the sense of minimally invasive surgery, clinical surgical skills, and confidence, significantly shortening the learning curve and growth curve, rapidly improving minimally invasive surgical skills, reducing complications in thoracoscopic minimally invasive surgery, greatly reducing training costs, and promoting the widespread application and development of thoracoscopic minimally invasive surgery.

[0044] The back of the thoracic module 3 is equipped with a spinal joint 10. The spinal joint 10 has the function and range of bending to simulate the left and right sides of the human body in order to simulate the normal surgical position. The spinal joint 10 has the function and range of bending to simulate the left and right sides of the human body in order to further meet the needs of surgical position simulation.

[0045] The thoracic module 3 includes skin tissue 31, subcutaneous tissue 32, muscle tissue 33, rib tissue 34, bone tissue 35, and thoracic organ tissue 36. The simulated components of skin tissue 31, subcutaneous tissue 32, muscle tissue 33, rib tissue 34, bone tissue 35, and thoracic organ tissue 36 are arranged to simulate the anatomical layers and structural layout of the normal human chest. It is used to simulate minimally invasive chest surgery training and provides a foundation for various operational training in thoracoscopic minimally invasive surgery.

[0046] The simulated human organs and tissues within the thoracic cavity module 3 are modularly assembled and installed. Their assembly, arrangement, and spatial layout completely simulate the normal chest organ structure and tissue layout. This modular assembly method facilitates disassembly, replacement, and maintenance, and allows for flexible adjustments based on different training needs.

[0047] The thoracic module 3 uses a semi-transparent micro-elastic material that simulates the shape, color, texture, elasticity, and other characteristics of the corresponding organs and tissues in the human chest. This makes the training operation similar to tactile sensation, highly visual and perceptible, and easy to enhance the realism of the surgery, teaching guidance, and assessment of operational proficiency. It allows beginners to observe the surgical operation process and organ and tissue structure more clearly.

[0048] The simulated human organs and tissues within the thoracic module 3 have high durability, allowing for multiple clamping, pushing, traction, and suturing operations without easily breaking. They can withstand a large number of training operations, extending the lifespan of the trainer and reducing usage costs. The surfaces of the simulated human organs and tissues within the thoracic module 3 have a slight adhesiveness, and the loose connective tissue connections between the simulated organs are used to simulate surgical operations in the interstitial spaces of free organs in actual clinical anatomy. This facilitates the simulation of actual clinical surgical operations, making the training operations closer to the real surgical experience and improving training effectiveness.

[0049] The thoracic module 3 can be fitted with simulated diseased tissue or animal organ tissue with the same anatomical name, such as the right lung of a pig, which is used to simulate the lesion treatment operation in thoracoscopic minimally invasive surgery. The spatial structure and pre-made surgical incision path of the thoracic module 3 are matched with the incision path of clinical thoracoscopic surgery.

[0050] By adopting the above technical solution:

[0051] By utilizing the flexion and extension functions of the simulated joints in the trainer, the trainer is adjusted to a suitable simulated surgical position. Simulated components of various organs, such as the heart, lungs, major blood vessels, and esophagus, are installed in the thoracic cavity module 3 to construct a complex thoracic organ structure. Simulated pericardial and myocardial lesion areas are set on the heart simulated component, and multiple simulated pulmonary nodules and bullae are set in the lung simulated component. At the same time, the adhesion situation in the thoracic cavity is simulated by applying an appropriate amount of adhesive material to the surface of some organ simulated components to simulate the loose connective tissue adhesion between organ tissues. In addition, red liquid is filled inside the blood vessels to simulate bleeding.

[0052] The trainees used thoracoscopic equipment and specialized minimally invasive surgical instruments to first perform simulated pleural adhesion separation. They carefully separated the adhesions between simulated organ components, gaining experience in applying force and skill during adhesion separation. Subsequently, they simulated a comprehensive thoracoscopic exploration of the pleural cavity, exposing surgical fields in different locations, precisely locating and exposing lesions such as pulmonary nodules, bullae, and pericardial lesions. They also simulated the exposure and anatomical dissection of pleural vessels and nerves, including pulmonary vessels, bullae and nodules resection, pericardial fenestration, drainage, and suturing, and mediastinal lymph node dissection—all minimally invasive thoracoscopic surgical procedures. Throughout the process, trainees were required to rationally plan surgical steps, use various surgical instruments precisely and flexibly, and complete the procedures in different pre-designed surgical scenarios.

[0053] According to different training needs, the head module 1, upper limb module 2, chest module 3, hip joint 4, knee joint 5, and lower limb module 6 are assembled through connector 7. When assembling the chest module 3, the simulated components of each human organ are installed in a modular manner according to the structure and layout of human chest organs to ensure accurate spatial positioning. At the same time, the elbow joint 9, shoulder joint 8, hip joint 4, knee joint 5, and spinal joint 10 are adjusted to simulate a suitable surgical position.

[0054] Users practice various minimally invasive thoracoscopic surgical procedures on the thoracic module 3 of the training device using surgical instruments such as thoracoscopes. This includes procedures for different surgeries and surgical positions; location, selection, incision, and closure of incision sites for minimally invasive surgery on different organs and tissues in the chest; adjustment and use of the thoracoscopic hand for the surgical field of view (up, down, left, right, deep, shallow, advance, retreat), focal length, and fiber optic angle; better observation, exposure, and stabilization of the surgical field; radiography, video recording, fluorescence, light intensity, and mode switching; and selection of incision sites at different locations to operate minimally invasive surgical instruments for simulating lesion traction, pushing, blocking, picking, prying, exposing, dissecting, separating, incising, suturing, hemostasis, and resection. Because the materials used in the thoracic module 3 have semi-transparent, slightly elastic, and slightly adhesive properties, users can obtain a near-realistic surgical experience and visual feedback. During training, instructors can observe and guide users' operations through the visual effects of the training device, promptly correcting errors and assessing operational proficiency.

[0055] When the simulated human organ tissue components inside the thoracic module 3 are worn or damaged, they can be easily disassembled and replaced, ensuring that the trainer is always in good working order and continuously supports training for thoracoscopic minimally invasive surgery.

[0056] The simulated components, consisting of skin tissue 31, subcutaneous tissue 32, muscle tissue 33, rib tissue 34, bone tissue 35, and thoracic organ tissue 36, simulate the anatomical layers and structural layout of the normal human chest. They are used to simulate minimally invasive chest surgery training and provide a foundation for various operational training in thoracoscopic minimally invasive surgery.

[0057] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
