Description

Technical Field

[0001] This invention relates to the field of surgical simulation technology, and in particular to a laparoscopic surgical simulation device. Background Technology

[0002] With advancements in medical technology, equipment, and surgical techniques, the proportion of laparoscopic surgeries has significantly increased in many hospitals in my country. Some medical institutions have even established dedicated minimally invasive or laparoscopic treatment centers. Laparoscopic surgery, with its numerous advantages such as small incisions, minimal tissue damage, less intraoperative bleeding, and faster postoperative recovery, has been widely accepted by doctors and patients. The proportion of laparoscopic surgery in surgical procedures is increasing, and laparoscopic surgery has become a trend in surgery. Furthermore, the level and scope of these surgeries are expanding accordingly. Minimally invasive treatment techniques, with laparoscopy as the mainstream, have become the primary means of diagnosing and treating surgical diseases. Current laparoscopic surgery first requires making at least two incisions in the patient's abdomen (usually on both sides, these incisions passing through the skin and muscle layers to connect the internal organs to the outside of the body). Then, the appropriate endoscope and surgical instruments are inserted into the patient's abdomen through these incisions. The lesion area is observed and located using the endoscope, and then the lesion area is treated using the surgical instruments. The location and size of the incision directly affect the overall surgical process and the patient's recovery. Only experienced doctors can make the appropriate incision location and size. New doctors cannot master this skill by simply observing, which prevents them from quickly gaining experience to perform laparoscopic surgery. Summary of the Invention

[0003] The main objective of this invention is to provide a laparoscopic surgery simulation device, which aims to solve the problem that novice doctors cannot quickly gain experience to perform laparoscopic surgery.

[0004] To achieve the above objectives, the technical solution proposed by this invention is as follows:

The vertical projection area formed by the rectangular through hole towards the installation space is located within the transparent layer. A detachable bionic layer is provided within the installation space, and the bionic layer is used for mounting on... The installation space simulates human skin and muscle layers, allowing the user to cut the bionic layer through the rectangular through-hole. A loading port is located on one side of the operating box, connecting to the installation space. A camera is positioned within the receiving space, on the side of the transparent layer facing away from the box cover, with its shooting area directly opposite the transparent layer.

[0006] Preferably, a limiting mechanism and a feeding mechanism are respectively provided on the side of the box cover facing the receiving space. The feeding mechanism is located on the side of the installation space away from the feeding port. The feeding mechanism is used to drive the bionic layer to move towards the feeding port after the bionic layer is cut by the cut, so that the bionic layer moves out of the operating box through the feeding port. The bionic layer moves along the feeding mechanism towards the feeding port to form a moving path. The limiting mechanism is located on the side of the installation space away from the feeding mechanism. The limiting mechanism is used to pass through the moving path after the bionic layer enters the installation space, so that the limiting mechanism and the feeding mechanism clamp and fix the bionic layer in the installation space.

The limiting plate is located on the side of the second telescopic member closer to the moving path, and the output end of the second telescopic member is connected to the limiting plate. The controller is electrically connected to the second telescopic member and is used to control the second telescopic member to drive the limiting plate to move so that the limiting plate is inserted into the moving path, thereby confining the bionic layer within the installation space.

[0010] Preferably, a positioning device is also provided on the side of the box cover away from the containing space.

The first projection lamp is disposed on the side of the bionic layer away from the receiving space, and the first projection lamp and the bionic layer are spaced apart. The first projection lamp is used to project a navel mark onto the side of the bionic layer away from the receiving space. One end of the connecting bracket is connected to the first projection lamp, and the other end of the connecting bracket is connected to the first electrically controlled slide. The controller is electrically connected to the first electrically controlled slide and the first projection lamp respectively. The controller is used to control the first electrically controlled slide to drive the first projection lamp to move to a preset position according to preset data, so that the first projection lamp projects a navel mark onto the bionic layer at the preset position.

[0012] Preferably, an auxiliary mechanism is provided within the accommodating space. The auxiliary mechanism is driven and connected to the camera. The controller is electrically connected to the auxiliary mechanism. The controller is used to control the auxiliary mechanism according to preset data, so that the auxiliary mechanism drives the camera to sequentially acquire practical images of each cut position.

[0013] Preferably, the auxiliary mechanism includes a second track and a second electrically controlled slide. The second track is disposed on the side of the operating box away from the box cover and extends along the limiting mechanism toward the unloading mechanism. The second electrically controlled slide is slidably connected to the second track, and the camera is disposed on the side of the second electrically controlled slide facing the box cover. The controller is electrically connected to the second electrically controlled slide and is used to control the second electrically controlled slide according to preset data so that the second electrically controlled slide drives the camera to move directly below the cut position.

[0014] Preferably, the auxiliary mechanism further includes a second projection lamp, which is disposed on the side of the second electrically controlled slide facing the box cover.

[0035] This invention proposes a laparoscopic surgery simulation device.

[0036] like Figures 1 to 4 The laparoscopic surgery simulation device shown includes an operating box 1, a camera 64, and a controller. The top of the operating box 1 is open, and an accommodating space 11 communicating with the open is provided inside the operating box 1. A box cover 2 is provided at the open, and a rectangular through hole 21 is provided on the side of the box cover 2 away from the accommodating space 11. A transparent layer 22 is provided on the side of the box cover 2 facing the accommodating space 11, and an installation space 23 is formed between the transparent layer 22 and the box cover 2. The vertical projection area formed by the rectangular through hole 21 towards the installation space 23 is located within the transparent layer 22. A detachable bionic layer 13 is provided within the installation space 23. 3 is used to simulate human skin and muscle layers within the installation space 23, allowing the user to cut the bionic layer 13 through the rectangular through-hole 21; a loading port 12 is opened on one side of the operation box 1, which connects to the installation space 23; a camera 64 is set within the receiving space 11, located on the side of the transparent layer 22 away from the box cover 2, with the shooting area of ​​the camera 64 facing the transparent layer 22; a controller is electrically connected to the camera 64, and the controller is used to control the camera 64 so that the camera 64 can acquire the actual operation image of the bionic layer 13 being cut through the transparent layer 22.

[0037] Specifically, when making laparoscopic incisions with a scalpel, Figure 1 For example, the scalpel makes an incision in the bionic layer from top to bottom. The practical video is a recording of the scalpel cutting the bionic layer 13 on the side closest to the receiving space 11 when the scalpel cuts the bionic layer 13 (i.e., Figure 1 (Image recording of the bottom side of the middle biomimetic layer 13 being cut open with a scalpel). Since the side of the human abdomen closest to the internal organs cannot be observed during actual surgery, the practical images can effectively help medical staff perceive the size of the opening on the side of the abdomen closest to the internal organs.

[0038] Specifically, laparoscopic surgery simulation equipment is mainly used to simulate surgeries performed in the human abdomen with two or three incision sites.

[0039] The bionic layer 13 simulates human skin and muscle layers and is detachably installed in the installation space 23. The user makes an incision in the bionic layer 13, and the camera 64 obtains the actual operation image of the incision cutting on the side of the bionic layer 13 near the receiving space 11 through the transparent layer 22. The user can also remove the bionic layer 13 to directly observe the incision. The user can summarize and review the entire incision cutting process through the actual operation image and the bionic layer 13, which effectively improves the user's operation experience in laparoscopic surgery.

[0040] Specifically, the controller is also used to acquire confirmation information and mark the corresponding practical images in the historical database as excellent images based on the confirmation information. The laparoscopic surgery simulation device also includes a communicator, which is electrically connected to the controller. The controller is also used to acquire identity information, determine the historical database based on the identity information, identify excellent images based on the historical data, and send the excellent images to the user through the communicator. The confirmation information is input by the user, who marks the practical images as excellent images themselves. By sending excellent images to the user, the incision cutting process can be reviewed before each practical simulation, allowing the user to summarize experience in real time before conducting further practical simulations, effectively improving the training effect of practical simulations.

[0041] Specifically, the cover 2 and the control box 1 are detachably fixed together. The cover 2 and the control box 1 are fixed together by bolts.

[0042] Specifically, a support plate is provided in the accommodating space 11. The support plate is located on the side of the feeding port away from the box cover 2. The support plate is used to support the bionic layer 13 entering from the feeding port 12.

[0043] Specifically, the controller is also used to acquire the location of internal organs and the location of lesions, and determine at least one preset location based on the location of internal organs and the location of lesions; the controller is also used to send the location of internal organs and the location of lesions to the user through a communicator, and acquire the data sent to the user through the communicator; the controller is also used to acquire the incision location, and determine the degree of overlap between the incision location and each preset location. When the degree of overlap between the incision location and one of the preset locations is greater than or equal to a preset value, the practical image is determined to be an excellent image; when the degree of overlap between the incision location and any preset location is less than the preset value, the practical image is marked as an erroneous image.

[0044] A limiting mechanism 4 and a feeding mechanism 3 are respectively provided on the side of the box cover 2 facing the receiving space 11. The feeding mechanism 3 is located on the side of the installation space 23 away from the feeding port 12. The feeding mechanism 3 is used to drive the bionic layer 13 to move towards the feeding port 12 after the bionic layer 13 is cut, so that the bionic layer 13 moves through the feeding port 12 to the outside of the operating box 1. The bionic layer 13 moves along the feeding mechanism 3 towards the feeding port 12 to form a moving path. The limiting mechanism 4 is located on the side of the installation space 23 away from the feeding mechanism 3. The limiting mechanism 4 is used to pass through the moving path after the bionic layer 13 enters the installation space 23, so that the limiting mechanism 4 and the feeding mechanism 3 clamp and fix the bionic layer 13 in the installation space 23. The controller is electrically connected to the feeding mechanism 3 and the limiting mechanism 4 respectively. The controller is used to control the limiting mechanism 4 to connect the installation space 23 and the feeding port 12 after the bionic layer 13 is cut, so that the feeding mechanism 3 pushes the bionic layer 13 out of the operating box 1.

[0045] Specifically, the rectangular through hole 21 extends along the moving path.

[0046] The transparent layer 22 and the box cover 2 are connected by two connecting plates 24, which are arranged in parallel and spaced apart. The installation space 23 is located between the two connecting plates 24, and the two connecting plates 24 extend along the moving path. The feeding mechanism 3 includes a first telescopic device 31 and a push plate 32. The first telescopic device 31 is located on the side of the receiving space 11 away from the limiting mechanism 4. The push plate 32 is located in the installation space 23 and between the two connecting plates 24. The output end of the first telescopic device 31 is connected to the push plate 32. The controller is electrically connected to the first telescopic device 31 and is used to control the first telescopic device 31 to drive the push plate 32 so that the push plate 32 pushes the bionic layer 13 to move towards the upper feeding port 12. After the user has finished cutting, the first telescopic device 31 pushes the bionic layer 13 towards the upper feeding port 12 through the push plate 32. At this time, the end of the bionic layer 13 away from the push plate 32 extends out from the feeding port 12, and the user can then directly pull out the bionic layer 13.

[0047] Specifically, push plate 32 is perpendicular to the two connecting plates.

[0048] Specifically, the bionic layer 13 is a disposable item that can be used for observation or evaluation after use.

[0049] A flexible layer is provided on the side of the connecting plate 24 facing the installation space 23. The flexible layer ensures a stable fit of the bionic layer 13.

[0050] The limiting mechanism 4 includes a second telescopic member 41 and a limiting plate 42. The second telescopic member 41 is located on the side of the receiving space 11 away from the unloading mechanism 3 and on one side of the moving path. The limiting plate 42 is located on the side of the second telescopic member 41 closer to the moving path, and the output end of the second telescopic member 41 is connected to the limiting plate 42. A controller is electrically connected to the second telescopic member 41 and is used to control the second telescopic member 41 to drive the limiting plate 42 to move, so that the limiting plate 42 is inserted into the moving path, thus confining the bionic layer 13 within the installation space 23. The bionic layer 13 enters the installation space 23 by direct insertion by the user. After insertion, the second telescopic member 41 drives the limiting plate 42 to insert into the moving path, so that the limiting plate 42 and the push plate 32 clamp and fix the bionic layer 13, preventing the bionic layer 13 from sliding freely during user cutting.

[0051] A positioning device 5 is also provided on the side of the lid 2 away from the receiving space 11. The controller is electrically connected to the positioning device 5 and is used to control the positioning device 5 so that the positioning device 5 projects a navel mark on the side of the bionic layer 13 away from the receiving space 11 according to preset data. In general laparoscopic surgery, the navel position is mainly used as the base point, and incisions are made on both sides of the navel and at the navel. By directly locating the navel position, it is convenient for the user to locate and make incisions at the remaining two incision positions.

[0052] The positioning device 5 includes a first track 51, a first electrically controlled slide 52, a connecting bracket 53, and a first projection lamp 54. The first track 51 is disposed on one side of the rectangular through hole 21 and is parallel to the movement path. The first electrically controlled slide 52 is slidably connected to the first track 51. The first projection lamp 54 is disposed on the side of the bionic layer 13 away from the receiving space 11 and is spaced apart from the bionic layer 13. The first projection lamp 54 is used to project a navel mark onto the side of the bionic layer 13 away from the receiving space 11. One end of the connecting bracket 53 is connected to the first projection lamp 54, and the other end of the connecting bracket 53 is connected to the first electrically controlled slide 52. The controller is electrically connected to the first electrically controlled slide 52 and the first projection lamp 54 respectively. The controller is used to control the first electrically controlled slide 52 to drive the first projection lamp 54 to move to a preset position according to preset data so that the first projection lamp 54 projects a navel mark onto the bionic layer 13 at the preset position. The first electrically controlled slide 52 moves the position of the first projection lamp 54 via the connecting bracket 53, which facilitates real-time changes to the position of the navel, effectively increasing the difficulty of incision cutting and improving the effect of practical simulation.

[0053] Specifically, the color of the navel marker is different from the color of the bionic layer 13.

[0054] Specifically, the controller determines the number of incorrect operations at each preset position and the total number of operations at each preset position based on a historical database; it determines the error rate at each preset position based on the total number of operations and the number of incorrect operations; it judges whether the error rate at each preset position is greater than or equal to a warning value. When the error rate at each preset position is less than the warning value, the controller selects one preset position to execute the step of having the first projection lamp 54 project a navel mark onto the bionic layer 13 at the preset position; when the error rate at at least one preset position is greater than or equal to the warning value, the controller selects one preset position with an error rate greater than or equal to the warning value to execute the step of having the first projection lamp 54 project a navel mark onto the bionic layer 13 at the preset position. By strengthening the simulation of user weaknesses, the accuracy of user simulation is effectively improved.

[0055] An auxiliary mechanism 6 is installed within the accommodating space 11. The auxiliary mechanism 6 drives and connects to a camera 64. A controller is electrically connected to the auxiliary mechanism 6 and controls the auxiliary mechanism 6 according to preset data, so that the auxiliary mechanism 6 drives the camera 64 to sequentially acquire practical images of each cutting position. The auxiliary mechanism 6 can improve the quality of the practical images.

[0056] The auxiliary mechanism 6 includes a second track 61 and a second electrically controlled slide 62. The second track 61 is located on the side of the operating box 1 away from the box cover 2 and extends along the limiting mechanism 4 towards the feeding mechanism 3. The second electrically controlled slide 62 is slidably connected to the second track 61, and a camera 64 is located on the side of the second electrically controlled slide 62 facing the box cover 2. A controller is electrically connected to the second electrically controlled slide 62 and is used to control the second electrically controlled slide 62 according to preset data, so that the second electrically controlled slide 62 drives the camera 64 to move directly below the cutting position. The arrangement of the second track 61 and the first track 51 ensures that the second electrically controlled slide 62 is always located directly below the cutting position, ensuring that the camera 64 is directly facing the cutting position to capture the actual operation video, effectively guaranteeing the quality of the actual operation video.

[0057] Specifically, the navel marker moves along the first track 51, and the projection path formed by the bionic layer 13 and the extension direction of the second track 61 coincide vertically.

[0058] The auxiliary mechanism 6 also includes a second projection lamp 63, which is disposed on the side of the second electrically controlled slide 62 facing the box cover 2. The second projection lamp 63 is used to project a recognition area onto the bionic layer 13. The controller is electrically connected to the second projection lamp 63 and is used to control the second projection lamp 63 according to preset data so that the second projection lamp 63 projects a recognition area onto the cut position.

[0059] Specifically, the recognition area is a ring of light and shadow, and the inside of the ring of light and shadow is the cut location.

[0060] Specifically, the controller determines the cutting path and annular lighting based on the simulation video, and checks whether the cutting path is within the annular lighting. If the cutting path is outside the annular lighting, the simulation video is marked as an error. If the cutting path is within the annular lighting, it checks whether the cutting path touches the annular lighting; if the cutting path touches the annular lighting, the simulation video is marked as an error. If the cutting path does not touch the annular lighting, it acquires a simulation image of the cut after the cut, and marks the cutting path route and cut length data on the simulation image based on the simulation image and the cutting path. The controller determines whether the simulation process is qualified based on the position of the cutting path, and marks qualified cutting paths with route and cut length data, providing real-time feedback to the user to help them understand the real-world situation of their simulation.

[0061] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
