[0001] The invention belongs to the technical field of medical training equipment, and more specifically, particularly relates to a surgical opening and closing abdomen training model. Background Art
[0002] The purpose of the simulation training of opening and closing abdomen: 1. Improve surgical skills: Through simulation training, doctors can become familiar with every step of the operation, including basic skills such as cutting and suturing the abdominal wall layer by layer, knotting, cutting and removing sutures. These exercises can help doctors become more skilled and accurate in real operations.
[0003] 2. Reduce surgical risks: Simulation training can avoid possible errors that may occur when operating on real patients, such as excessive incision of the abdominal wall leading to intestinal damage. Through simulation training, doctors can better master surgical skills and reduce accidents and complications during surgery.
[0004] 3. Enhance safety awareness: The error prompts and feedback mechanisms in simulation training can help doctors identify and correct errors in operation, thereby improving the safety of surgery. For example, the setting of simulated intestinal tract can train doctors to avoid damaging the intestinal tract in the abdominal cavity during operation.

BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 A schematic diagram of the structure of the present invention; Figure 2 A side view of the present invention; Figure 3 A cross-sectional view of the present invention; Figure 4 This is an enlarged view of part A; In the figure: a double-branch movable mechanism 1, a model head 2, a head connecting seat 3, an abdominal cavity 4, a skin tissue mechanism 5, a skin layer 6, a subcutaneous tissue 7, a peritoneum 8, a slot 9, a stabilizing plate 10, a channel 11, and an inflation tube 12. DETAILED DESCRIPTION
[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0018] A surgical abdominal opening and closing training model, a surgical abdominal opening and closing training model, comprises a model upper body, the abdomen of the model upper body is provided with an abdominal opening and closing simulation mechanism, the inner side of the front end of the model upper body is provided with a foam filler, and both sides of the model upper body are provided with a double-branch movable mechanism 1; a model head 2 is installed on the top of the model upper body, a head slot is provided in the center of the top of the model upper body, and a head connecting seat 3 is fixedly connected to the bottom of the model head 2, which has a more realistic and durable appearance, and realizes the training of trainees' abdominal opening and closing skills from the overall patient perspective.
[0019] The abdomen opening and closing simulation mechanism includes an abdominal cavity 4 and a detachable skin tissue structure 5 located on the upper end surface of the abdominal cavity 4. Under the premise of controlling costs, multiple experiments can be carried out by detaching the skin tissue structure 5. After multiple experiments, if the skin tissue structure 5 does not meet the requirements of the practice, it is only necessary to replace the old skin tissue structure 5 with a new one to continue the practice operation, saving costs and avoiding waste.
[0020] The skin tissue structure 5 includes the skin layer 6, subcutaneous tissue 7 and peritoneum 8 from top to bottom. Simulating the skin tissue structure plays an important role in medical teaching and training. By using simulated skin, medical staff can better understand the physiological and pathological characteristics of human skin, thereby improving their professional skills and ability to cope with actual clinical situations. The upper end surface of the abdominal cavity 4 is provided with a card slot 9 around it, and the skin tissue structure 5 is inserted into the card slot 9 and placed. A transparent sticker is provided on the skin tissue to facilitate the removal of the skin tissue structure 5.
[0021] The upper body of the model is made of pvc material.
[0022] Benefits of using PVC material: Durability and stability: PVC material has high durability and stability. It can remain stable under high temperature radiation and will not break or decompose easily. In addition, PVC material is not easily affected by ultraviolet light and ozone, so it has a longer life when used in natural environments.
[0023] Details and Realism: PVC material can present a high degree of details during the manufacturing process, making the model look more real or cute. This characteristic makes PVC models highly valuable in collection and decoration.
[0024] Good processing performance: PVC material has good ductility and can be carefully corrected by heating and shaping when encountering structural problems. In addition, PVC material is cheap, easy to use and easy to paint, which is particularly suitable for mass production.
[0025] Environmental protection and safety: PVC material has good chemical inertness, does not release harmful substances, is friendly to the human body and the environment, and is especially suitable for children's toys. It has moderate hardness and is safe and suitable for playing.
[0026] The skin tissue structure 5 is made of silicone.
[0027] A stabilizing plate 10 is provided on the rear end surface of the model's upper body. Since the model's upper body imitates a real person but is not a real person after all, it cannot lie on the operating table as stably as a real person and will move. Therefore, a stabilizing plate 10 is provided on the model's upper body to stabilize it. At the same time, the stabilizing plate 10 can also be inserted into the groove of the operating table in the practice room to prevent it from moving.
[0028] The model upper body is provided with a channel 11, which passes through the abdominal cavity 4 and the outside of the model upper body. An inflation tube 12 is installed in the channel 11. The inflation tube 12 is connected to an air bag at one end away from the abdominal cavity 4, and the other end of the inflation tube 12 is connected to a balloon. The balloon is inflated by pinching the air bag. The two sides of the model upper body are transparent, and the size of the balloon is determined by observation to control the number of times the air bag is pinched. The two sides of the model upper body are installed with the model upper body through mounting holes and mounting columns.
[0029] In the first embodiment, the doctor simulates the three-layer anatomical structure of the abdomen, namely, the skin layer 6, the subcutaneous tissue 7 and the peritoneum 8. Doctors who use the simulation training model have significantly improved their accuracy and time efficiency in real surgeries. For example, training with the simulated umbilical model significantly improves doctors’ accuracy when opening and closing the abdomen, and reduces damage to the intestines in the abdominal cavity.
[0030] By placing a balloon in the abdominal cavity 4 , the doctor conducts laparotomy training in a simulated experiment, and determines the depth of the laparotomy by observing whether the balloon explodes. Through multiple experiments, the doctor can achieve the goal of laparotomy without damaging the intestines in the abdominal cavity 4 .
[0031] Furthermore, the skin tissue on the abdominal cavity 4 can be replaced, and the experiment can be repeated multiple times by multiple people.
[0032] In the second embodiment, during daily training, doctors can perform basic surgical skills training such as layer-by-layer incision and suturing of the skin tissue 5, knotting, thread cutting, and suture removal, so as to improve students' understanding and mastery of abdominal surgical operation skills.
[0033] Functional features of this device: High degree of simulation: The surgical opening and closing abdominal training model is made of polymer materials with high degree of simulation. The skin layer 6, subcutaneous tissue 7 and peritoneum 8 are elastic and clearly layered, and can perform abdominal incision and suturing operations.
[0034] Multi-layer anatomical structure: The model simulates the three basic anatomical structures of the abdominal wall, including the skin layer 6, subcutaneous tissue 7 and peritoneum 8. The layer-by-layer incision and suturing exercises can help practitioners better understand the surgical process.
[0035] Simulated internal organs: There is a balloon in the abdominal cavity 4, which can be inflated. The trainee must avoid damaging the balloon during operation.
[0036] The role of models in medical training: Improve surgical skills: By repeatedly practicing surgical operations such as incision and suturing, medical professionals can become more familiar with the surgical process and improve surgical efficiency and safety.
[0037] Avoid risks in actual operations: Practicing operations in a simulated environment can reduce the risk of harm to patients during actual surgery.
[0038] Versatility: In addition to incision and suturing exercises, it can also be used to practice wound cleaning, dressing changes and other nursing skills. The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
