Description

Technical Field

[0001] This invention relates to the field of demonstration teaching aids, and more particularly to a pediatric orthopedic repair demonstration box. Background Technology

[0002] In pediatric orthopedic clinical diagnosis, treatment, and teaching training, practical training in fracture repair surgery relies on professional demonstration tools. However, existing tools have several shortcomings: most tools can only statically simulate the morphology of leg fractures, lacking precise replication of leg blood vessels. This prevents operators from effectively training the crucial skill of avoiding major blood vessels when making incisions, resulting in a disconnect from actual clinical surgical scenarios. Simulated muscles are mostly disposable, and postoperative incisions cannot be repaired. Frequent replacements not only increase material costs but also reduce training efficiency. Furthermore, the fracture fracture location, opening size, and simulated muscle angles of existing tools are fixed, making it difficult to simulate diverse fracture cases and different incision directions, thus limiting the improvement of operators' ability to handle complex clinical situations. In addition, some tools have fixed structures and cannot be adjusted according to the operator's posture and observation angle, affecting the convenience and adaptability of training. These problems lead to poor clinical training results and fail to meet the needs of cultivating practical skills in pediatric orthopedic professionals. Therefore, we propose a pediatric orthopedic repair demonstration box to solve the aforementioned problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing a pediatric orthopedic repair demonstration kit.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a pediatric orthopedic repair demonstration box, comprising a box body, an anterior chamber opened in the middle of the front side of the box body, cylinders rotatably connected to the upper and lower parts of the anterior chamber, mounting plates installed on the inner side of the cylinders near each other, and multiple simulated blood vessels fixedly connected to the end of each mounting plate near each other, each simulated blood vessel having a heating wire inside, and a power receiving chamber fixedly connected to the end of each mounting plate away from the simulated blood vessel, each power receiving chamber being used to supply power to the heating wire inside the simulated blood vessel, and a simulated leg bone one and a simulated leg bone two penetrating through the middle of each mounting plate. Both simulated leg bone one and simulated leg bone two are slidably connected to the mounting plate. The ends of simulated leg bone one and simulated leg bone two that are close to each other are provided with corresponding breaks. The side of simulated leg bone one away from the break is provided with a rotating shaft one. The side of simulated leg bone two away from the break is provided with a rotating shaft two. The outer circumference of rotating shaft one and rotating shaft two is provided with threaded sections. Rotating shaft one and rotating shaft two are threadedly connected to simulated leg bone one and simulated leg bone two respectively through the threaded sections. Simulated muscle bodies are provided between the mounting plates. Simulated leg bone one, simulated leg bone two and simulated blood vessels are all located inside the simulated muscle bodies.

[0005] Preferably, the outer circumference of the silo is provided with toothed grooves on one side, and gears are meshed with the rear side of each toothed groove. A rotating shaft passes through the middle of each gear, and the rotating shaft and the gear are fixedly connected.

[0006] Preferably, a stepper motor is mounted on the top of the rotating shaft, the stepper motor is installed inside the housing, and electric push rods are rotatably connected to both sides of the rear part of the front chamber, with rotating seats installed on the telescopic ends of the electric push rods.

[0007] Preferably, the telescopic ends of the electric push rods are all rotatably connected to connecting seats via rotating seats, and the end of each connecting seat away from the rotating seat is fixedly connected to a side mold shell.

[0008] Preferably, a mold cavity is provided in the middle of the adjacent ends of the side mold shells, and connecting strips are installed on the upper and lower parts of the rear side of the side mold shells, with connecting pieces rotatably connected between the connecting strips on both sides.

[0009] Preferably, each of the silos is equipped with an end seat at the end away from the mounting plate, and each of the rotating shafts is fixedly connected to a servo motor at the end away from the simulated leg bone 1 and simulated leg bone 2, and the servo motors are all installed inside the end seat.

[0010] Preferably, each of the mounting discs has a limiting ring at one end that is close to the other, and the limiting ring is located on the outside of the simulated blood vessel.

[0011] Preferably, a fixed shaft is fixedly connected to the middle of both sides of the box, and a fixed frame is rotatably connected to the lower part of the box via the fixed shaft.

[0012] Preferably, each of the upper sides of the fixing frame has a positioning screw, which is used for positioning after the box is rotated.

[0013] Preferably, a control panel is installed on one side of the upper front end of the housing, and the control panel is used to control the other drive devices.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In practical use, the demonstration box allows people to practice leg fracture repair surgery. The simulated body can simulate the leg of a fracture patient, the simulated leg bone one and simulated leg bone two can simulate the patient's tibia and fibula, the fracture site can simulate the patient's fracture wound, and the simulated blood vessels can simulate the blood vessels in the patient's leg. This makes it convenient for people to demonstrate repair surgery and train them on how to avoid the main blood vessels in the leg when making surgical incisions at the fracture point. It simulates actual surgical situations, highly restores the surgical scene, improves the relevance of practical training, and trains people's surgical incision skills.

[0015] After the demonstration training is completed, users can activate the electric push rod via the control panel. The electric push rod causes the side mold shells to flip, allowing them to wrap around the simulated body. Then, the heating wires heat the surrounding simulated body, causing it to remelt. Once the simulated body has melted into a liquid state, the heating wires stop working. At this point, the semiconductor cooling chip inside the side mold shell is activated to cool and solidify the liquid colloid in the internal cavity. This eliminates the cuts from the previous demonstration training, allowing the simulated body to return to its complete state for the next training demonstration. This avoids the need to replace the demonstration teaching aids, significantly reducing training costs and achieving substantial cost reduction for materials.

[0016] During the repair process of the simulated muscle, the servo motor inside the end seat can be activated. The servo motor drives the first and second rotating shafts to rotate, which in turn move the simulated leg bones one and two via threaded sections. This allows for adjustment of the fracture position and opening size, enabling the simulation of more cases and facilitating improved demonstration and training effects. Furthermore, a stepper motor can drive the rotating shaft to rotate, which in turn drives the gears to rotate synchronously. This, in turn, drives the silo meshing with the gears to rotate, allowing for changes in the orientation of the simulated muscle. This facilitates training demonstrations with different incision directions and meets the training needs for different incision angles. This addresses the problems of traditional teaching aids having limited fracture scenarios and training effects, helping operators handle complex clinical cases.

[0017] In practical use, users can first loosen the positioning screws on the fixed shaft and fixed frame, allowing them to rotate the box according to their needs and tilt it. After adjusting the box to the appropriate angle, users can rotate the positioning screws on both sides in sequence. Tightening the positioning screws will make the ends of the positioning screws firmly abut against the circumference of the fixed shaft, thereby positioning the box and maintaining its current tilt angle. This facilitates subsequent demonstration and training, allowing the demonstration box to match the operating postures and observation angles of different operators. It solves the problems of traditional teaching aids being fixed and unadjustable and having poor operating comfort, thus improving the convenience and experience of the training process.

[0020] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] like Figures 1-7The pediatric orthopedic repair demonstration box shown includes a box body 101. A front chamber 104 is opened in the middle of the front side of the box body 101. A silo 110 is rotatably connected to both the upper and lower parts of the front chamber 104. An installation plate 122 is installed on the inner side of the silo 110 at the adjacent end. Multiple simulated blood vessels 120 are fixedly connected to the adjacent end of each installation plate 122. Each simulated blood vessel 120 is equipped with a heating wire. A power receiving chamber 126 is fixedly connected to the end of each installation plate 122 away from the simulated blood vessels 120. The power receiving chamber 126 is used to supply power to the heating wires inside the simulated blood vessels 120. A simulated leg bone 119 and a simulated leg bone 2 123 pass through the middle of each installation plate 122. Both the simulated leg bone 119 and the simulated leg bone 2 123 are connected to the installation plate 122. 22 Sliding connection, the simulated leg bone 119 and simulated leg bone 2 123 are respectively provided with corresponding fractures 127 at the ends of the simulated leg bone 119 and the simulated leg bone 2 123. The simulated leg bone 119 is provided with a rotating shaft 124 on the side away from the fracture 127, and the simulated leg bone 2 123 is provided with a rotating shaft 2 125 on the side away from the fracture 127. The outer circumference of the rotating shaft 124 and the rotating shaft 2 125 is provided with a threaded section 128. The rotating shaft 124 and the rotating shaft 2 125 are respectively threaded to the simulated leg bone 119 and the simulated leg bone 2 123 through the threaded section 128. The simulated muscle body 116 is provided between the mounting plates 122. The simulated leg bone 119, the simulated leg bone 2 123 and the simulated blood vessel 120 are all located inside the simulated muscle body 116. Furthermore, in practical implementation, the demonstration box allows for training in leg fracture repair surgery. Simulated muscle 116 simulates the leg of a fractured patient, simulated leg bone 119 and simulated leg bone 2 123 simulate the tibia and fibula, fracture site 127 simulates the fracture wound, and simulated blood vessels 120 simulate the blood vessels in the leg. This facilitates demonstrations of the repair surgery and allows trainees to practice avoiding major blood vessels in the leg when making surgical incisions at the fracture point, simulating actual surgical procedures and providing convenient training. The surgical incision proficiency is enhanced during the repair of the simulated muscle 116. The servo motor inside the endplate 111 can then be activated, driving the rotation of shaft 124 and shaft 125. These shafts, via the threaded section 128, move the simulated leg bone 119 and simulated leg bone 123, thereby adjusting the position and size of the fracture 127 and adapting to changes in the fracture condition. This allows for the simulation of more cases, facilitating improved demonstration and training effectiveness.

[0022] The outer circumference of the silo 110 is provided with a toothed groove 109 on one side. A gear 112 is meshed with the rear side of the toothed groove 109. A rotating shaft 113 passes through the middle of the gear 112. The rotating shaft 113 and the gear 112 are fixedly connected. A stepper motor is installed on the top of the rotating shaft 113. The stepper motor is installed inside the housing 101. Electric push rods 107 are rotatably connected to both sides of the rear part of the front chamber 104. A rotating seat 115 is installed on the telescopic end of the electric push rod 107. A connecting seat 108 is rotatably connected to the telescopic end of the electric push rod 107 through the rotating seat 115. A side mold shell 105 is fixedly connected to the end of the connecting seat 108 away from the rotating seat 115. A mold cavity 121 is provided in the middle of the end of the side mold shell 105 that is close to it. Connecting strips 117 are installed on the upper and lower parts of the rear side of the side mold shell 105. A connecting piece 114 is rotatably connected between the two connecting strips 117. Furthermore, in practical implementation, after the demonstration training is completed, people can activate the electric push rod 107 via the control panel 106. The electric push rod 107 can drive the side mold shell 105 to rotate, so that the side mold shells 105 can wrap around the simulated muscle body 116. The limiting ring 118 and the mounting plate 122 can seal the side mold shell 105. At this time, people can activate the heating wire in the simulated blood vessel 120. The operation of the heating wire can heat the surrounding simulated muscle body 116, causing the simulated muscle body 116 to remelt. When the simulated muscle body 116 melts into a liquid state, the heating wire stops working. At this time, the internal mechanism of the side mold shell 105 is activated. The semiconductor cooling chip cools and solidifies the liquid colloid in the internal mold cavity 121, thereby eliminating the cuts from the previous demonstration training of the simulated body 116. This allows the simulated body 116 to return to its complete state, facilitating the next training demonstration and avoiding the need to replace the demonstration teaching aid. This significantly reduces material costs and is beneficial for practical use. A stepper motor drives the rotating shaft 113 to rotate, which in turn drives the gear 112 to rotate synchronously. This, in turn, drives the silo 110, which meshes with the gear 112, to rotate, thus changing the orientation of the simulated body 116 and facilitating training demonstrations with different cutting directions.

[0023] In this configuration, an end seat 111 is installed at the end of the silo 110 away from the mounting plate 122. A servo motor is fixedly connected to the ends of the rotating shaft 124 and the rotating shaft 2 125 away from the simulated leg bone 119 and the simulated leg bone 2 123. The servo motors are all installed inside the end seat 111. A limit ring 118 is provided at the end of the mounting plate 122 that is close to it. The limit ring 118 is located on the outside of the simulated blood vessel 120. A fixed shaft 102 is fixedly connected to the middle of both sides of the box 101. A fixed frame 103 is rotatably connected to the lower part of the box 101 through the fixed shaft 102. A positioning screw is passed through the upper side of the fixed frame 103. The positioning screw is used to position the box 101 after it is rotated. A control panel 106 is installed on the upper side of the front end of the box 101. The control panel 106 is used to control the other drive devices. Furthermore, in specific implementation, people can first loosen the positioning screws on the fixed shaft 102 and the fixed frame 103, so that people can rotate the box 101 according to their own needs, so that the box 101 is in an inclined state. After the box 101 is adjusted to a suitable angle, people can rotate the positioning screws on both sides in sequence. By tightening the positioning screws, the ends of the positioning screws can be tightly pressed against the periphery of the fixed shaft 102, thereby achieving the positioning of the box 101 and keeping the box 101 at the current tilt angle, which is convenient for people to carry out subsequent demonstration and training work.

[0024] Working principle: In practical use, the demonstration box allows users to practice leg fracture repair surgery. The simulated muscle 116 simulates the leg of a fractured patient, while simulated leg bone 119 and simulated leg bone 2 123 simulate the tibia and fibula. The fracture site 127 simulates the fracture wound, and the simulated blood vessels 120 simulate the blood vessels in the leg. This facilitates demonstrations of the repair surgery and allows users to practice avoiding major blood vessels in the leg when making incisions at the fracture point, simulating actual surgical conditions and improving surgical incision skills. After the demonstration training is complete, the user can activate the electric push rod 107 via the control panel 106. The electric push rod 107 rotates the side mold shell 105, allowing the side mold shells to rotate. The mold shell 105 can enclose the simulated muscle body 116 through the side mold shell 105, and the side mold shell 105 can be closed by the limiting ring 118 and the mounting plate 122. At this time, people can activate the heating wire in the simulated blood vessel 120. The operation of the heating wire can heat the surrounding simulated muscle body 116, so that the simulated muscle body 116 can remelt. When the simulated muscle body 116 melts into a liquid state, the heating wire stops working. At this time, the semiconductor cooling chip inside the side mold shell 105 is activated to cool and solidify the liquid colloid in the internal mold cavity 121, thereby eliminating the incision of the simulated muscle body 116 in the previous demonstration training, so that the simulated muscle body 116 can be restored to a complete state, which is convenient for the next training demonstration and avoids the need to replace the mold. The teaching aids, by significantly reducing material costs, facilitate practical use. During the repair of the simulated muscle 116, the servo motor inside the endplate 111 can be activated. This servo motor drives the first rotating shaft 124 and the second rotating shaft 125 to rotate. The rotating shafts 124 and 125, through the threaded section 128, move the simulated leg bone 119 and the simulated leg bone 2 123, thereby adjusting the position and opening size of the fracture 127 and adapting to changes in the fracture condition. This allows for the simulation of more cases, improving demonstration and training effectiveness. Furthermore, a stepper motor can drive the rotating shaft 113 to rotate, which in turn drives the gear... The gear 112 rotates synchronously, which drives the silo 110 meshing with the gear 112 to rotate, thereby changing the direction of the simulated body 116. This facilitates training demonstrations of different cutting directions. In actual use, users can first loosen the positioning screws on the fixed shaft 102 and the fixed frame 103, allowing them to rotate the housing 101 according to their needs, tilting the housing 101. After adjusting the housing 101 to a suitable angle, users can rotate the positioning screws on both sides in sequence. Tightening the positioning screws ensures that the ends of the positioning screws are firmly pressed against the periphery of the fixed shaft 102, thereby positioning the housing 101 and maintaining its current tilt angle, facilitating subsequent demonstration and training.
