DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0018] Please refer to Figures 1 to 5 The core component of the mold is a stable vertical plate 1, on which a rotating shaft 2 is connected in a through-type rotation. A unique hollow spherical shell 3 is tightly fixed at one end of the rotating shaft 2. The spherical shell consists of two parts: an opaque hemispherical shell 31 and a transparent hemispherical shell 32, which are cleverly fixed together. The interior of the hollow spherical shell 3 is filled with transparent silicone 4, and in this layer of silicone, a profiling channel 5 simulating female genitalia is carefully set. This profiling channel 5 not only includes a simulated vagina 51 connected to the through hole 6 on the side wall of the spherical shell, but also carefully designed simulated uterine cavity 52 and simulated cervix 53 located between the two, so as to restore the real scene to the greatest extent.

[0019] A driving bevel gear 7 is installed at the other end of the rotating shaft 2, and a driving device 8 installed on the vertical plate 1 cooperates with it. The driving device 8 is composed of a mounting plate 81, a driving shaft 82, a driven bevel gear 83 and a driving gear 84. One end of the driving shaft 82 is fixed to the driven bevel gear 83, and the other end is connected to the driving gear 84. A slide 9 is cleverly designed on the vertical plate 1, in which a rack 10 can slide smoothly, and the rack 10 forms a tight meshing connection with the driving gear 84. By pushing the rack 10 forward and backward to move in the slide 9, the entire driving device 8 can be easily driven to operate, thereby driving the driving bevel gear 7, the rotating shaft 2 and the hollow spherical shell 3 to rotate, thereby realizing the flipping function of the spherical shell.

[0020] In order to ensure the stability and accuracy of the rack 10 during the movement, a first stroke limit plate 11 and a second stroke limit plate 12 are specially provided. In addition, a rotating shaft 13 is rotatably connected inside the rack 10, and a torsion spring 14 is sleeved on the shaft, and the two ends of the spring are respectively engaged with the rotating shaft 13 and the rack 10. Two limit columns, a first limit column 15 and a second limit column 16, are also fixed on the rotating shaft 13. A limit groove 17 is provided on the top wall of the slideway 9 of the vertical plate 1, and these two limit columns can perfectly match the limit groove 17. When the rack 10 moves to the limit position, by rotating the rotating shaft 13 and releasing the elastic force of the torsion spring 14, the limit column can automatically snap into the limit groove 17, thereby locking the rotation position of the ball shell. When the first stroke limit plate 11 contacts the vertical plate 1, the opaque hemispherical shell 31 will automatically flip to the top; and when the second stroke limit plate 12 contacts the vertical plate 1, the transparent hemispherical shell 32 will be at the top.

[0021] It is worth mentioning that the vertical plate 1 is made of iron material, and the first travel limit plate 11 and the second travel limit plate 12 are magnetic, which can generate a certain attraction with the vertical plate 1 to further increase stability. In order to facilitate the rotation of the rotating shaft 13, a driving ring 18 is also fixed at the end of the rotating shaft.

[0022] In addition, a horizontal board 19 is fixed at the bottom of the vertical board 1, and stepped mounting holes 20 are provided at the four corners of the horizontal board, so that the entire teaching mold can be firmly fixed on the platform by screws to prevent the mold from moving during the simulated surgery. At the top of the horizontal board 19, an equipment box 21 is also provided for storing surgical instruments, so that users can use and store them at any time.

[0023] In actual operation, the user can switch different operation modes by rotating the hollow spherical shell 3. When the transparent hemispherical shell 32 is located at the top, the user can intuitively observe the position of the intrauterine contraceptive device and the ring remover and each link in the upper ring removal operation, thereby deepening the understanding and mastery of the operation. When the opaque hemispherical shell 31 is located at the top, the real surgical environment can be simulated to conduct strict assessment and training for young doctors. This design not only improves the practicality and pertinence of teaching, but also makes the mold extremely durable and reusable.

[0024] The working principle of the upper ring removal surgery teaching mold is summarized as follows: Simulation structure: The core of the teaching mold is a hollow spherical shell 3, which consists of an opaque hemispherical shell 31 and a transparent hemispherical shell 32, and is filled with transparent silica gel 4. A female genital channel 5 is provided in the hollow spherical shell, including a simulated vagina 51, a simulated cervix 53 and a simulated uterine cavity 52, which is used to simulate the real anatomical environment. A through hole 6 is provided on the side wall of the hollow spherical shell 3, facing the entrance of the female genital channel 5, to allow the simulated instrument to enter.

[0025] Rotation mechanism: The hollow spherical shell 3 is connected to the vertical plate 1 through the rotating shaft 2 and can rotate on the vertical plate 1. An active bevel gear 7 is fixed to one end of the rotating shaft 2, and the other end is connected to the hollow spherical shell 3. When the position of the hollow spherical shell 3 needs to be changed, the active bevel gear 7 can be controlled to rotate through the driving device 8, thereby driving the entire hollow spherical shell 3 to rotate.

[0026] Driving system: The driving device 8 includes a mounting plate 81, a driving shaft 82, a driven bevel gear 83, a driving gear 84, and a rack 10 in the slideway 9. By manually pushing or pulling the rack 10, the driving gear 84 can be rotated, and then the driving bevel gear 7 is driven to rotate via the driving shaft 82 and the driven bevel gear 83, and finally the hollow spherical shell 3 is rotated.

[0027] Limiting design: In order to ensure that the hollow spherical shell 3 can stop accurately at the required position, a first travel limiting plate 11 and a second travel limiting plate 12 are provided, which correspond to the upper positions of the opaque hemispherical shell 31 and the transparent hemispherical shell 32 respectively. At the same time, a rotating shaft 13 with a torsion spring 14 is provided in the rack 10, and the first limiting column 15 and the second limiting column 16 on the rotating shaft 13 can be inserted into the limiting groove 17 of the top wall of the slideway 9 under certain circumstances to fix the position of the hollow spherical shell 3.

[0028] Magnetic adsorption: the vertical plate 1 is made of iron material, and the first stroke limit plate 11 and the second stroke limit plate 12 are magnetic, which helps to provide additional stability when the hollow spherical shell 3 reaches the specified position.

[0029] Auxiliary functions: The horizontal plate 19 provides a stable foundation and has stepped mounting holes 20 for easy fixation; the equipment box 21 facilitates the storage and management of surgical instruments.

[0030] The user can choose to place the transparent hemispherical shell 32 or the opaque hemispherical shell 31 on top as needed to meet different training needs. The transparent hemispherical shell 32 can be used to visually observe the operation process inside the uterine cavity, while the opaque hemispherical shell 31 can be closer to the actual surgical environment to help doctors practice and assess. This teaching mold not only helps train medical personnel to master skills, but also can be reused due to its reasonable structural design, thereby improving resource utilization.

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.
