Description

Technical Field

[0001] The present invention relates to the technical field of teaching models, and in particular to a pelvic organ prolapse grading and scoring demonstration and teaching model. Background Art

[0002] Existing pelvic organ prolapse teaching models often lack sufficient interactivity and intuitiveness. Many models are limited to simple static displays, failing to simulate the dynamic changes of organ prolapse in actual clinical practice. Such models also lack the necessary practical and operational experience for learners. Furthermore, some traditional models are relatively simple in construction and lack sufficient adjustability, making them incapable of personalized demonstrations and teaching based on different situations.

[0003] Many existing pelvic organ prolapse (POP) teaching models are fixed structures and cannot dynamically simulate different degrees of uterine prolapse. Learners can only see a certain state and cannot intuitively understand the changing process of different stages. These methods or teaching aids are difficult to help learners establish accurate clinical judgments. Although some current teaching tools can display the pelvic organ prolapse quantitative staging method (Pelvic Organ Prolapse Quantification, POP-Q) grading, they often lack clear reference marks. For example, the various anatomical points of the vaginal wall lack adjustable positioning devices, which makes it difficult for students to grasp the key anatomical positions when measuring, resulting in large errors and affecting the accuracy of the scoring.

[0004] Many models are damaged during use due to excessive handling. Existing materials lack durability, especially for areas that require frequent contact and repeated adjustment, such as the vaginal wall model. These areas are prone to wear and tear after prolonged use. This design not only shortens the model's lifespan but can also compromise teaching effectiveness. Summary of the Invention

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Please see the attached Figure 1 -Attached Figure 4 , an embodiment of the present invention provides a pelvic organ prolapse grading and scoring demonstration and teaching model, comprising: a magnetic plate 1, the outer wall of which is rotatably connected to a support box 7; an observation plate 2, fixedly connected to the inside of the magnetic plate 1; a transparent barrel 15, the outer wall of which is fixedly connected to the outer wall of the magnetic plate 1, and the inner wall is slidably connected to a uterus model 14; a vaginal wall model 16, one end of which is fixedly connected to the inner wall of the transparent barrel 15, and the other end is connected to the uterus model 14; a teaching component, which is arranged on the outer wall of the magnetic plate 1 for assisting teaching; the teaching component includes magnetic blocks 5 and a scoring plate 4, a plurality of magnetic blocks 5 are attached to the outer wall of the magnetic plate 1 by magnetic force, and the scoring plate 4 is attached to the outer wall of the magnetic plate 1 by magnetic force; a scale bar 3 is provided on the side of the magnetic plate 1 close to the observation plate 2, the scale bar 3 is marked with positive and negative scales, and the scale range is 10 cm to -10 cm; the vaginal wall model 16 is a synthetic rubber material that is slightly elastic and can be repeatedly used without breaking;

[0033] Specifically, the movement of the uterus model 14 drives the vaginal wall model 16 to move, so that the uterus model 14 slides inside the transparent barrel 15, and the movement of the uterus model 14 squeezes the vaginal wall model 16, so that the vaginal wall model 16 slides inside the transparent barrel 15. The magnetic block 5 is picked up and moved to be adsorbed on the magnetic plate 1 to mark the positions of the uterus model 14 and the vaginal wall model 16, and the position information of the uterus model 14 and the vaginal wall model 16 is recorded by the scoring board 4 according to the scale on the scale bar 3. Quantification, POP-Q is used to score and stage pelvic organ prolapse. The position is marked by adsorbing the magnetic block 5 on the magnetic plate 1. According to the definition of "6 points and 3 lines" in the POP-Q scoring system, the corresponding position is marked by the magnetic block 5, and its corresponding scale is its value. In addition, the length of the three lines can be clearly seen. After that, the information is recorded on the scoring board 4. According to the value of the "6 points and 3 lines", the POP-Q stage can be obtained. The synthetic rubber material of the vaginal wall model 16 can make the vaginal wall model 16 move repeatedly in the transparent barrel 15, thereby achieving the effect of increasing the service life.

[0034] The traction mechanism 6 is mounted on one side of the magnetic plate 1 and is used to adjust the position of the uterine model 14. The traction mechanism 6 includes a fixed frame 603, the outer wall of which is fixedly connected to the outer wall of the magnetic plate 1. A take-up wheel 602 is provided inside the fixed frame 603, one end of which is fixedly connected to a rotating block 601. A traction line 605 is provided inside the take-up wheel 602, and both ends of the traction line 605 are respectively fixedly connected to the two ends of the uterine model 14. The outer wall of the traction line 605 is slidably connected to a plurality of limiting wheels 604, and the outer wall of the limiting wheel 604 is fixedly connected to the outer wall of the fixed frame 603.

[0035] Specifically, the take-up wheel 602 is driven to rotate by rotating the rotating block 601, so that the take-up wheel 602 reels in one end of the traction line 605 and pays out the other end. The take-up and pay-out of the take-up wheel 602 causes the traction line 605 to slide on the limiting wheel 604, so that the traction line 605 pulls one end of the uterus model 14 to move. The take-up wheel 602 is rotated in the opposite direction by rotating the rotating block 601 in the opposite direction, and the traction line 605 pulls the other end of the vaginal wall model 16 to move, so that the uterus model 14 slides inside the transparent barrel 15, thereby pulling the uterus model 14 to move in the opposite direction.

[0036] An adjustment mechanism 8 is mounted on one side of the magnetic plate 1 and is used to adjust the angle of the magnetic plate 1. The adjustment mechanism 8 includes a support rod 801, one end of which is rotatably connected to a connecting block 802, an outer wall of the connecting block 802 is fixedly connected to the outer wall of the magnetic plate 1, and one end of the support rod 801 is internally threadedly connected to a limit block 803, and an outer wall of the limit block 803 is slidably connected to the interior of the support box 7.

[0037] Specifically, by pulling the limit block 803 to move, the limit block 803 drives one end of the support rod 801 to move, so that the support rod 801 rotates on the connecting block 802 and moves through the connecting block 802, thereby pushing the magnetic plate 1 to rotate on the support box 7, thereby adjusting the angle of the magnetic plate 1.

[0038] A partition 12 is fixedly connected to the interior of the support box 7, and a limit plate 9 is fixedly connected to one side of the outer wall of the partition 12. An air bag 10 is provided on the upper surface of the limit plate 9, and an air supply pipe 11 is fixedly connected to one end of the air bag 10. A valve 13 is fixedly connected to the outer wall of the uterus model 14, which is used to inflate and deflate the uterus model 14.

[0039] Specifically, the support box 7 is divided by a partition 12 so that the divided part is used to store items. The air bag 10 is pulled to move the air pipe 11, and one end of the air pipe 11 is inserted into the valve 13. Then, the air bag 10 is pressed to allow gas to pass through the air bag 10 into the air pipe 11. The gas is then transported through the air pipe 11 to the inside of the valve 13 and the uterus model 14, causing the uterus model 14 to expand due to the entry of gas, thereby achieving the effect of adjusting the size of the uterus model 14.

[0040] Working principle: First, pull the limit block 803 to slide inside the support box 7, and drive the support rod 801 to move, so that the support rod 801 rotates on the connecting block 802, and pushes the connecting block 802 to move, so that the connecting block 802 pushes the magnetic plate 1 to move, so that the magnetic plate 1 rotates on the support box 7, thereby adjusting the angle of the magnetic plate 1, and then pull the air bag 10 to move, drive the air pipe 11 to move, and insert the air pipe 11 into the inside of the valve 13, and press the air bag 10 to allow the gas to enter the air pipe 11 and be transported to the inside of the valve 13 and the uterine model 14, thereby adjusting the size of the uterine model 14, and drive the take-up wheel 602 to rotate by rotating the rotating block 601, so that the take-up wheel 602 reels one end of the traction line 605, so that The other end of the line is released, and the line-reeling wheel 602 is used to reel in and release the line so that the traction line 605 slides on the limiting wheel 604, so that the traction line 605 pulls one end of the uterus model 14 to move, and the line-reeling wheel 602 is rotated in the opposite direction by rotating the rotating block 601 in the opposite direction, thereby causing the traction line 605 to pull the other end of the vaginal wall model 16 to move, thereby causing the uterus model 14 to slide inside the transparent barrel 15, thereby pulling the uterus model 14 to move in the opposite direction, and the movement of the uterus model 14 drives the vaginal wall model 16 to move, so that the uterus model 14 slides inside the transparent barrel 15, and the movement of the uterus model 14 squeezes the vaginal wall model 16, so that the vaginal wall model 16 slides inside the transparent barrel 15, according to the quantitative staging method for pelvic organ prolapse. The POP-Q (Pelvic Organ Prolapse Quantification) system is used to score and stage pelvic organ prolapse. By moving a magnetic block 5, it attaches to a magnetic plate 1 to mark the positions of the uterine model 14 and vaginal wall model 16. According to the "6 points and 3 lines" definition of the POP-Q scoring system, the corresponding positions are marked with magnetic block 5, and the corresponding scale value is the corresponding value. The length of the three lines can also be clearly seen. This information is then recorded on the scoring plate 4. Based on the "6 points and 3 lines" values, the POP-Q stage can be determined, guiding clinical diagnosis and treatment. Students or new practitioners can use this demonstration and teaching model to more intuitively grasp the POP-Q scoring system.
