[0002] Laparoscopic surgical training devices play an important role in modern medical education and surgical training. Current training systems usually include a training box that simulates the internal environment of the human body, which is designed to accommodate various simulated organs and tissues to provide realistic operation scenarios. In addition, these systems are equipped with electronic accessories such as cameras, displays, light sources, and various surgical instruments, which work together to simulate the visual and operating experience in actual surgery. With such a setup, surgeons can practice and master complex laparoscopic surgical skills without involving real patients.

[0003] Although existing laparoscopic surgery training devices can effectively improve doctors' professional skills, they are large in size and require the integration of multiple components to achieve complete training functions. This design not only increases the cost and complexity of the equipment, but also limits its portability and scope of application.

[0004] Due to the large size and weight of these systems, they are often fixed in specific training centers or hospitals and difficult to quickly carry to other locations, such as doctors' homes. Therefore, for medical institutions that need to flexibly arrange training time and location, traditional laparoscopic surgery training devices are not ideal and also limit the learning opportunities of trainees.

[0039] See also Figure 1-6 A laparoscopic surgery training system based on virtual reality technology includes a wearable operating component 1, an operating table 3, a storage box 2 capable of storing the wearable operating component 1 and the operating table 3, and a main control module 4 arranged inside the storage box 2.

[0040] Among them, the wearing operation component 1 includes VR glasses 11, a laparoscope 12 and abdominal forceps 13, which are all common equipment in the prior art. During the specific design process, the size can be adjusted according to the actual practice needs. The image content displayed in the VR glasses 11 can be the display content displayed when the doctor performs remote VR surgery in the prior art. It can display the scene of the simulated operating room scene and the content captured by the laparoscope 12, so that the operator can experience the surgical scene in an immersive way after wearing the VR glasses.

[0041] The storage box 2 includes a main box 21 with an opening on the surface, a sub-box 22 disposed on the surface of the main box 21 and capable of blocking the opening, and a locking portion 23 capable of fixing the sub-box 22 on the surface of the main box 21. The operating table 3 includes an isolation plate 31 disposed inside the main box 21, and an abdominal cavity simulation cover 32 disposed on the isolation plate 31. A cavity capable of accommodating a training rubber block is formed between the isolation plate 31 and the abdominal cavity simulation cover 32. The training rubber block is a simulation device commonly used for medical staff training and is usually made of silicone. It can allow medical staff to perform simulated surgical suture operations on a practice rubber block through a laparoscope 12 and abdominal forceps 13. The surface of the abdominal simulation cover 32 is provided with a plurality of openings for the laparoscope 12 and the abdominal forceps 13 to extend into. The main control module 4 is arranged between the isolation plate 31 and the main box 21, and can be used for the transmission and reception of signals of the laparoscope 12 and the VR glasses 11. An interface for connecting an external power cord is provided on the surface of the main box 21, so that the main control module 4 can be connected to an external power supply to power the VR glasses 11 and the laparoscope 12.

[0042] Example 1

[0043] To ensure the storage effect, the storage box 2 can store the operating table 3 as a whole. At this time, a storage chamber is reserved between the abdominal simulation cover 32 and the sub-box 22 for storing the wearing operating component 1. The main box 21 is provided with a supporting member that can support the abdominal simulation cover 32. The supporting member can be a common block structure. The abdominal simulation cover 32 can be placed on the supporting member and taken out according to the operator's usage requirements.

[0044] A rubber block fixing seat is provided on the surface of the isolation plate 31, and an exercise rubber block is provided on the surface of the rubber block fixing seat. The hard rubber block fixing seat can effectively prevent the exercise rubber block from being pushed by the operator during the exercise and affecting the exercise effect. The number of sub-boxes 22 is greater than or equal to one, and one end of the sub-box 22 is connected to the surface of the main box 21 through a movable hinge structure 27. Through the design of multiple sub-boxes 22, multiple wearing operation components 1 can be stored to meet the training design of multiple users.

[0045] Example 2

[0046] Different from Example 1, in order to allow the wearable operating component 1 to dock with the main control module 4 after opening the sub-box 22, a switching unit 24 is provided inside the sub-box 22, and the switching unit 24 is connected to the VR glasses 11 and the laparoscope 12 through wires. The switching unit 24 can be a common electrical signal and current conversion module in the prior art, and the surfaces of the sub-box 22 and the main box 21 are respectively provided with a fixed electrical connector 25 and a movable electrical connector 26 connected to the switching unit 24 and the main control module 4, and the fixed electrical connector 25 and the movable electrical connector 26 are adapted to each other.

[0047] To facilitate the operator's control, technical personnel in this field can set a control panel on the adapter unit 24, or set a socket on the adapter unit to allow the VR glasses 11 and the laparoscope 12 to be inserted into the interface. When the VR glasses 11 and the laparoscope 12 are in the sub-box, they do not need to be connected to the adapter unit 24 all the time, so as to avoid damage to the interface caused by the VR glasses 11 and the laparoscope 12 being connected to the adapter unit 24 all the time.

[0048] The movable hinge structure 27 includes a connecting plate 271 arranged on the surface of the sub-box 22, a sliding plate 272 arranged on the surface of the main box 21, and a movable shaft connecting the connecting plate 271 and the sliding plate 272. The surface of the sliding plate 272 is provided with a sliding groove for the sliding of the movable shaft, so that after the sub-box 22 is opened, only the sub-box 22 needs to be pushed to allow the movable electrical connector 26 to dock with the fixed electrical connector 25, thereby quickly realizing the connection between the wearable operating component 1 and the main control module 4, saving operation time.

[0049] Example 3

[0050] What is different from Example 2 is that, in order to ensure the storage effect of the storage chamber, an isolation shell 28 with an opening on the surface is provided inside the storage chamber of the sub-box 22, and a sealing cover 29 is provided on the surface of the isolation shell 28. When the sealing cover 29 is covered on the opening, the wearing operation component 1 and the adapter unit 24 are both located inside the isolation shell 28 and the sealing cover 29. After the sealing cover 29 is covered, the sub-box 22 is closed, and the abdominal cavity simulation cover 32 can support the sealing cover 29 to prevent the items contained in the isolation shell 28 from falling out of the main box 21. Therefore, there is no need to set a corresponding snap-in structure on the sealing cover 29.

[0051] At the same time, in order to reduce the overall mechanical structure of the device and ensure the simplicity and reliability of the overall system, the locking part 23 includes a fixed shaft 231 arranged inside the main box body 21, and a locking head 232 arranged on the fixed shaft 231. The isolation plate 31, the abdominal simulation cover 32 and the surface of the auxiliary box body 22 are all provided with openings adapted to the fixed shaft 231. One end of the fixed shaft 231 can extend to the outside of the auxiliary box body 22, and the surface of the locking head 232 is in contact with the auxiliary box body 22. At the same time, a lifting handle is provided on the surface of the locking head 232 away from the auxiliary box body 22, and the locking head 232 is connected to one end of the fixed shaft 231 through a thread.

[0052] In the description of this technology, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this technology can be understood according to specific circumstances.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
