Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly to a gynecological examination model. Background Technique

[0002] The role of routine gynecological examinations is to provide early prevention and treatment for some gynecological diseases. First, doctors will check for tumors, inflammation, condyloma acuminata, etc. in the vulva. Secondly, a vaginal examination is performed to check for deformities, inflammation, and abnormal leucorrhea. The cervical examination looks for cervical inflammation, cervical erosion, etc. In addition, a gynecological examination also includes a palpation examination to check the size, shape, and position of the uterus. This series of examinations are all routine examinations. If the operator is skilled and experienced, it will not cause pain to the patient and can detect early lesions in a timely manner. However, gynecological examinations involve the privacy of patients, and due to the unique shyness and conservative concepts of Chinese women, beginners have very few opportunities for practice, which is not conducive to the mastery and proficient application of gynecological examination techniques.

[0003] For this reason, various models for gynecological examination training have emerged. For example, the utility model patent with the application number CN201120550426.6 is equipped with uteri and appendages in different states, and injecting air can adjust the sizes of fibroids and cysts. It can perform colposcopy, rectal examination, cervical and vaginal smear, bimanual examination, and triple examination, and can be used for teaching demonstrations and practical exercises. Another example is the utility model patent with the application number CN202221582757.2, which uses replaceable uterine and uterine appendage model components to simulate the pathological conditions of uteri of different sizes and various appendages under different pathological conditions, such as simulating gynecological pelvic examinations under pathological conditions such as uterine fibroids, adenomyosis, and ovarian cysts. Sensors are set on the model components. If a student accurately palpates and describes this part of the model components, corresponding evaluation scores can be obtained.

[0004] However, in the prior art, in the models for gynecological examinations, the position of the uterus is usually fixed. However, in actual situations, for different patients, the position of the uterus will show various deviations. The model with a fixed uterine position has too large a gap from actual operations and cannot meet the teaching requirements such as students' hands-on palpation to familiarize themselves with the human body structure.

[0027] Please refer to Figure 1-2 , in a preferred embodiment of the present utility model, a gynecological examination model includes a simulation shell 1.

Among them, the legs of the model are one - third of the thighs; a uterine model 12 is arranged inside the simulation shell 1, and the uterine model 12 is connected to the simulation shell 1 through a vaginal model 11. The vaginal orifice of the vaginal model 11 is arranged on the simulation shell 1. Uterine appendage models 13 are arranged on both sides of the uterine model 12. Both the uterine model 12 and the uterine appendage models 13 are located in the abdomen of the simulation shell 1; preferably, the simulation shell 1, the uterine model 12, the uterine appendage models 13 and the vagina 11 are all made of human - simulation silicone

[0028] Furthermore, a number of water sacs 14 are arranged on both the uterine model 12 and the uterine appendage models 13. The water sacs 14 are made of elastic materials and are attached to the outer wall of the corresponding model in the natural state. The water sacs 14 are connected to a water - injection device located outside the simulation shell 1 through water - injection pipes 141; the water sacs 14 can be inflated by injecting water into the water sacs 14 to simulate pathological conditions such as fibroids and cysts. Preferably, the water sacs 14 are connected to the water - injection pipes 141 through corrugated pipes 142. One end of the corrugated pipe 142 is connected to the water sac 14, and the other end is connected to the inner wall of the simulation shell 1 and is communicated with the water - injection pipe 141. The corrugated pipe 142 has the ability of folding and stretching. Under the action of the corrugated pipe 142, even if a long connecting pipe is not arranged inside the simulation shell 1, it can be ensured that when the positions of the uterine model 12 and the uterine appendage models 13 change, the water sacs 14 on the uterine model 12 and the uterine appendage models 13 will not be separated from the water - injection pipes 141, and the water sacs 14 can be normally injected with water. More preferably, the water - injection pipes 141 on a number of water sacs 14 are all communicated with a main pipe, and the main pipe is connected to the water - injection device through a water pump. A valve is arranged at one end of each water - injection pipe 141 close to the main pipe. Water in the water - injection device is injected into the water sacs 14 through the water pump, and the water sacs 14 are inflated to simulate pathological conditions such as fibroids or cysts; the water in the water sacs 14 can also be sucked back into the water - injection device by the water pump. At this time, the water sacs 14 are attached to the corresponding models in the natural state; a valve is arranged on each water - injection pipe 141, and the inflation of each water sac 14 can be controlled separately according to the situation, and the pathological conditions of fibroids and cysts of different sizes can be simulated

[0029] Further, the uterine model 12 is movably installed in the simulation housing 1. An adjusting rod 151 is provided on the uterine model 12. One end of the adjusting rod 151 is located on the uterine model 12, and the other end is connected to a universal ball 15. The universal ball 15 is movably installed on the simulation housing 1 through a support base 152 and is located on one side of the vaginal orifice. The support base 152 is embedded in the simulation housing 1. A spherical groove 1521 is formed in the support base 152. The spherical groove 1521 has two notches, and the two notches are arranged on both sides of the support base 152. These two sides are respectively the inner and outer sides of the simulation housing 1. The diameter of the notch is smaller than the diameter of the universal ball 15. A part of the universal ball 15 is movably accommodated in the spherical groove 1521, and a part extends out of the spherical groove 1521 through the notch. Among them, the part of the universal ball 15 located inside the simulation housing 1 is installed with the adjusting rod 151, and the part located outside the simulation housing 2 is installed with an operating rod 153. The operating rod 153 and the adjusting rod 151 are arranged on opposite sides in the radial direction of the universal ball 15. The end of the operating rod 153 not connected to the universal ball 15 is located outside the simulation housing 1. A fixing device is provided on the simulation housing 1 to prevent the universal ball 15 from rotating. Driven by the operating rod 153 and the universal ball 15, the adjusting rod 151 adjusts the deviation of the uterine model 12, so as to simulate uterine deviations in different directions. Then, the fixing device is used to prevent the universal ball 15 from rotating, and the uterine model 12 can be fixed at multiple positions as needed, making the position change of the uterine model 12 closer to the actual operation and meeting the teaching requirements such as students' hands-on touch to familiarize themselves with the human body structure.

One end of the fixing rod 161 is fixedly connected to the simulation housing 1, and the other end movably penetrates through the fixing block 16, and the locking nut 162 is threadedly connected to the other end. The fixing block 16 is located between the simulation housing 1 and the locking nut 162. Under the action of the locking nut 162, the fixing block 16 abuts against the universal ball 15, so that the universal ball 15 abuts against the groove wall of the spherical groove 1521. The universal ball 15 is clamped by the groove wall of the spherical groove 1521 and the fixing block 16 together, thereby preventing the universal ball 15 from rotating. More preferably, two fixing rods 161 are provided on the fixing block 16. The two fixing rods 161 are respectively arranged at both ends of the fixing block 16 in the length direction and are located on both sides of the operating rod 153. A locking nut 162 is threadedly connected to each fixing rod 161. The locking nuts lock the fixing block 16 from both sides, which can enhance the locking effect and further improve the effect of the fixing block 16 in fixing the universal ball 15. More preferably, a limiting block 1611 for preventing the locking nut 162 from falling out is provided at the end of the fixing rod 161 that is not connected to the simulation housing 1. The locking nut 162 is located between the fixing block 16 and the limiting block 1611; the size of the limiting block 1611 is larger than the inner diameter of the locking nut 162. It can not only prevent the loss of the locking nut, but also facilitate the timely rotation of the locking nut 162 when it is necessary to fix the universal ball 15.
