Description

Technical Field

[0001] The present invention specifically relates to a laparoscopic surgery simulation training platform. Background Art

[0002] Laparoscopic surgery, with its advantages of minimal trauma and rapid recovery, has become a routine procedure in general surgery, obstetrics and gynecology, and other fields. Wound suturing (especially continuous suturing deep within tissues) is a challenging aspect of laparoscopic surgery, requiring the surgeon to possess precise instrument manipulation and spatial positioning skills. To enhance surgeons' suturing skills, laparoscopic surgery simulation training platforms are widely used in clinical teaching.

[0003] However, existing training platforms have the following significant drawbacks: 1. Fixed puncture point location: Traditional platforms typically have pre-set, non-adjustable puncture markers or suture holes. Due to the significant differences in suture spacing requirements (typically 3mm, 5mm, 8mm, etc.) across different patient tissue thicknesses and surgical sites (e.g., gastrointestinal / vascular anastomosis), fixed designs cannot meet diverse training needs, making it difficult for trainees to adapt to the flexible adjustments required in real-world surgeries.

[0004] 2. Single-source tissue mechanical feedback: Existing simulated tissues are mostly homogeneous fillers (such as silicone blocks), with unadjustable density and penetration resistance. In actual surgery, however, the penetration resistance of tissues like fat, muscle, and fascia varies significantly (fat resistance is approximately 2–5N, while muscle resistance can reach 8–15N). These fixed mechanical properties prevent trainees from developing precise force control tailored to the specific characteristics of different tissues, potentially leading to over-deep sutures and tissue tears during real-life surgery.

[0005] 3. Low training efficiency: Trainees need to repeatedly change training molds of different specifications to practice various suture spacings, and are unable to dynamically simulate complex tissue environments, which seriously restricts the efficiency of skill advancement. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a laparoscopic surgery simulation training platform that can adapt to the requirements of different suture spacing, improve the trainees' operational flexibility for different spacings, and thus improve the aesthetics of the suture line.

[0007] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a laparoscopic surgery simulation training platform, including a display device, a laparoscope, surgical forceps, a surgical needle and a surgical thread, and also including: A simulation box, wherein a top cover of the simulation box is provided with a plurality of artificial pneumoperitoneum components; A simulated knife edge is provided in the simulation box; There are two simulated puncture marking lines, which are arranged oppositely and parallel to each other on both sides of the simulated blade, and the simulated puncture marking lines include a plurality of simulated puncture marking holes evenly spaced; The distance adjustment mechanism is connected to the two simulated puncture marking lines and is used to adjust the distance between the simulated puncture marking holes on the two simulated puncture marking lines.

[0008] Furthermore, the distance adjustment mechanism includes an adjusting rod, a guide rod, a mounting plate, a slider, an elastic member and a first rotational power source. There are two adjusting rods and two guide rods, and both are arranged in parallel on both sides of the simulated blade. There are multiple mounting plates, and multiple mounting plates are arranged in two rows linearly to form a mounting plate group. The two mounting plate groups are respectively located on both sides of the simulated blade. Each mounting plate is provided with a simulated puncture identification hole. A slider is fixed on each mounting plate, and all the sliders can be slidably mounted on the guide rod on the same side. The adjusting rod is a bidirectional screw, and the spiral rotation directions of the two ends of the bidirectional screw are opposite. The middle slider is fixed to the middle part of the bidirectional screw, and the sliders on both sides are threadedly connected to the bidirectional screw. The first rotational power source is used to simultaneously drive the two adjusting rods to rotate, and an elastic member is provided between each adjacent two sliders.

[0009] Furthermore, the elastic member can be slidably mounted on the guide rod or the adjusting rod.

[0010] Furthermore, it also includes a flexible simulated tissue, which is arranged in the simulation box, the simulated blade is opened on the upper surface of the flexible simulated tissue, and the mounting plate is arranged on the upper surface of the flexible simulated tissue and can slide on the flexible simulated tissue.

[0011] Furthermore, the flexible simulated tissue includes a shell, a filler with adjustable density and a density adjustment mechanism. The simulated blade is arranged on the shell, and two parallel mounting grooves are opened on the shell. The two mounting grooves are respectively located on both sides of the simulated blade. The mounting plate can be slidably embedded in the mounting groove, the filler is filled in the shell, and the density adjustment mechanism is used to adjust the density of the filler.

[0012] Furthermore, the filler includes a cushion.

[0013] Furthermore, the density adjustment mechanism includes a pressing plate and a pushing member, the pressing plate presses the end surface of the soft pad away from the simulated blade, and the pushing member is used to push the pressing plate to move toward or away from the simulated blade.

[0014] Furthermore, the pushing member includes a second rotational power source, a bidirectional screw, a pushing block and a pushing rod. The bidirectional screw is horizontally arranged at the bottom of the outer shell, and one end of the bidirectional screw can be rotatably extended out of the simulation box. The second rotational power source is used to drive the bidirectional screw to rotate. There are two pushing blocks, and the two pushing blocks are respectively mounted on the two ends of the bidirectional screw and threadedly connected to the bidirectional screw. There are two pushing rods, and the two pushing rods are arranged opposite to each other. The top end of the pushing rod is hinged to the pressure plate, and the bottom end is hinged to the pushing block on the same side.

[0015] Beneficial effects of the present invention: When using the above-mentioned laparoscopic surgery simulation training platform, the laparoscope, surgical needle, surgical thread and surgical forceps are inserted into the simulation box from the artificial pneumoperitoneum component, and the situation inside the simulation box is observed through the display device. By operating the surgical forceps, the surgical needle is clamped to perform suturing. When suturing, the display device is assisted to observe the surgical needle with the surgical forceps, and the needle is inserted from the simulated puncture mark hole on one side of the simulated incision and exited from the simulated puncture mark hole on the other side. The simulated incision suturing is completed. When the suturing of the simulated puncture mark holes with this spacing is more proficient, the spacing between the simulated puncture mark holes can be adjusted to perform suturing training with different spacings.

[0016] This training platform can be used to train the fine movements of suturing, thereby improving the aesthetics of the suture line. In addition, since the distance adjustment mechanism can adjust the spacing of the simulated puncture mark holes, suturing operations with different spacings can be trained, further improving the training quality.

[0019] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] See Figures 1 to 3 The present invention provides a laparoscopic surgery simulation training platform, including a display device, a laparoscope, surgical forceps, a surgical needle, a surgical thread, a simulation box 100, a simulated incision 200, a simulated puncture marking line 300 and a distance adjustment mechanism 400.

[0021] Specifically, the top cover of the simulation chamber 100 is equipped with multiple artificial pneumoperitoneum components. A simulated incision 200 is disposed within the simulation chamber 100. Two simulated puncture marking lines 300 are disposed opposite and parallel to each other on either side of the simulated incision 200. Each simulated puncture marking line 300 includes multiple evenly spaced simulated puncture marking holes 310. A distance adjustment mechanism 400 is connected to the two simulated puncture marking lines 300 and is used to adjust the distance between the simulated puncture marking holes 310 on the two simulated puncture marking lines 300.

[0022] During use, extend the laparoscope, surgical needle, surgical thread and surgical forceps from the artificial pneumoperitoneum assembly into the simulation box 100, and observe the situation inside the simulation box 100 through the display device. By operating the surgical forceps, clamp the surgical needle to perform suturing. When suturing, assist in observing the display device, clamp the surgical needle with the surgical forceps, insert it from the simulated puncture marking hole 310 on one side of the simulated incision 200, and exit from the simulated puncture marking hole 310 on the other side. Complete the suturing of the simulated incision 200. When you are proficient in suturing the simulated puncture marking holes 310 with this spacing, you can adjust the spacing between the simulated puncture marking holes 310 to perform suturing training with different spacings.

[0023] Through this training platform, the fine movements of suturing can be trained, thereby improving the aesthetics of the suture line. In addition, since the distance adjustment mechanism 400 can adjust the spacing of the simulated puncture marking holes 310, suturing operations with different spacings can be trained, further improving the training quality.

[0024] In this embodiment, the distance adjustment mechanism 400 includes an adjustment rod 410, a guide rod 420, a mounting plate 430, a slider 440, an elastic member 450 and a first rotational power source 460. There are two adjustment rods 410 and two guide rods 420, and both are arranged in parallel on both sides of the simulated blade 200. There are multiple mounting plates 430, and the multiple mounting plates 430 are arranged in two rows to form a mounting plate 430 group. The two mounting plate 430 groups are respectively located on both sides of the simulated blade 200, and each mounting plate 430 is provided with a Simulating the puncture identification hole 310, a slider 440 is fixed on each mounting plate 430, and all the sliders 440 can be slidably mounted on the guide rod 420 on the same side. The adjusting rod 410 is a bidirectional screw, and the spiral rotation directions of the two ends of the bidirectional screw are opposite. The middle slider 440 is fixed to the middle part of the bidirectional screw, and the sliders 440 on both sides are threadedly connected to the bidirectional screw. The first rotational power source 460 is used to drive the two adjusting rods 410 to rotate at the same time, and an elastic member 450 is provided between each adjacent two sliders 440.

[0025] During specific implementation, the elastic member 450 can be slidably mounted on the guide rod 420 or the adjustment rod 410 .

[0026] During use, when it is necessary to adjust the distance between the simulated puncture identification holes 310, the two adjustment rods 410 are driven to rotate at the same time by the first rotational power source 460. When the sliders 440 on both sides are driven to move closer to the middle, the elastic member 450 can push the middle slider 440 to move accordingly. The slider 440 drives the mounting plate 430 to move, which can reduce the distance between the mounting plates 430, thereby shortening the distance between the simulated puncture identification holes 310; conversely, the distance between the simulated puncture identification holes 310 can be increased.

[0027] It should be noted that, in the embodiment, the first rotational power source 460 can be any mechanism that can simultaneously drive the two adjustment rods 410 to rotate, such as a servo motor combined with a pulley drive, a gear drive, or the like.

[0028] As a preferred embodiment, the device also includes a flexible simulated tissue 500, which is arranged in the simulation box 100, the simulated blade 200 is opened on the upper surface of the flexible simulated tissue 500, and the mounting plate 430 is arranged on the upper surface of the flexible simulated tissue 500 and can slide on the flexible simulated tissue 500.

[0029] The flexible simulated tissue 500 simulates human tissues of different densities, thereby training the strength during the needle insertion process, thereby further improving the training effect.

[0030] Specifically, the flexible simulated tissue 500 includes a shell 510, a filler 520 with adjustable density and a density adjustment mechanism 530. The simulated blade 200 is arranged on the shell 510. Two parallel mounting grooves are opened on the shell 510. The two mounting grooves are respectively located on both sides of the simulated blade 200. The mounting plate 430 can be slidably embedded in the mounting groove. The filler 520 is filled in the shell 510. The density adjustment mechanism 530 is used to adjust the density of the filler 520.

[0031] During use, when suturing, the surgical needle is sequentially passed through the simulated puncture mark hole 310 on one side, then through the flexible simulated tissue 500, and then out from the simulated puncture mark hole 310 on the opposite side. During the needle insertion process, the hardness of the flexible simulated tissue 500 can be felt.

[0032] In this embodiment, the filler 520 includes a soft cushion. The density adjustment mechanism 530 includes a pressing plate 531 and a pushing member 532. The pressing plate 531 presses the soft cushion on the end surface away from the simulated blade 200, and the pushing member 532 is used to push the pressing plate 531 toward or away from the simulated blade 200.

[0033] During use, when the density of the cushion is to be changed, the pressing plate 531 is pushed by the pushing member 532 to compress or loosen the cushion, thereby changing its density and experiencing different puncture forces.

[0034] In this embodiment, the pushing member 532 includes a second rotational power source 5321, a bidirectional screw rod 5322, a pushing block 5323 and a pushing rod 5324. The bidirectional screw rod 5322 is horizontally arranged at the bottom of the shell 510, and one end of the bidirectional screw rod 5322 can be rotated to extend out of the simulation box 100. The second rotational power source 5321 is used to drive the bidirectional screw rod 5322 to rotate. There are two pushing blocks 5323, and the two pushing blocks 5323 are respectively arranged at both ends of the bidirectional screw rod 5322 and are threadedly connected to the bidirectional screw rod 5322. There are two pushing rods 5324, and the two pushing rods 5324 are arranged opposite to each other, and the top end of the pushing rod 5324 is hinged to the pressure plate 531, and the bottom end is hinged to the pushing block 5323 on the same side.

[0035] During use, when the second rotating power source 5321 is started, the two-way screw rod 5322 can be rotated to drive the two pushing blocks 5323 to move closer to or away from each other, so that the pressure plate 531 rises or falls, thereby adjusting the density of the cushion.

[0036] The above-mentioned laparoscopic surgery simulation training platform can be used to train the precision of laparoscopic surgery wound suturing and the operator's force control.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
