Description

Technical Field

[0001] This invention belongs to the field of treatment training model technology, specifically involving a training model kit for simulating sclerotherapy of lymphangioma under ultrasound guidance. Background Technology

[0002] Lymphangioma, also known as lymphangioma, is a benign vascular malformation originating from abnormal lymphatic vessel development during the embryonic period, leading to local lymphatic vessel dilation or the formation of cystic structures. It can be classified into large cystic, mixed, and microcystic lymphangiomas. It is most common in infants and young children (approximately 90% are discovered before the age of 2), and is frequently found in the head, neck, limbs, or trunk. It is usually painless and presents as a soft, poorly defined mass.

[0003] The main treatment method involves puncturing the cyst cavity under ultrasound guidance, aspirating the fluid, and then injecting medication for sclerotherapy. The sclerosing agent is injected into the lymphangioma to induce degeneration and necrosis of the lymphangioma endothelial cells, thereby achieving the therapeutic goal. The effectiveness of sclerotherapy for infantile lymphangiomas is closely related to the type and location of the lesion. Cystic lymphangiomas vary in size and location, and medications (such as bleomycin) are used to induce atrophy and closure of the abnormal lymphatic vessels. The fluid in the lymphangioma cyst is mainly a pale yellow, clear liquid or a dark red, bloody liquid.

[0004] Currently, there is no model kit for simulating the operation of extracting fluid from cysts and injecting sclerosing agents under ultrasound guidance for cysts of different locations, depths, and sizes. This makes it difficult for trainees to quickly master this technique. Therefore, this invention proposes a training model kit for simulating sclerotherapy of lymphangioma under ultrasound guidance. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a training model kit for simulating sclerotherapy of lymphangioma under ultrasound guidance.

[0006] The technical solution adopted to solve the above-mentioned technical problems is: a training model kit for simulated sclerotherapy injection of lymphangioma under ultrasound guidance, including a sterile package. A support plate is placed inside the sterile package. The upper end of the support plate has a model body placement slot, a syringe placement slot, several lymphatic simulation liquid bottle placement slots, several cyst model placement slots of different sizes, and several scalp needle placement slots. A hemispherical silicone model body for lymphangioma treatment training is placed in the model body placement slot. An elastic block is fixedly connected inside the syringe placement slot, and several syringes of different sizes are engaged within the elastic block. Different sizes of simulated lymphangioma cyst models are placed in each of the several cyst model placement slots. Different sizes of scalp needles are placed in each of the scalp needle placement slots. Different colored lymphatic simulation liquid bottles are placed in each of the lymphatic simulation liquid bottle placement slots.

[0007] Furthermore, several labels are affixed to the upper surface of the support plate, and the labels correspond to the positions of the syringe, scalp needle, and lymphatic simulation fluid bottle, respectively.

[0008] The above technical solution enables rapid identification of different types of syringes, scalp needles, and lymphatic simulation fluid bottles containing different colored liquids via labels. This quick identification avoids confusion, especially during intense training sessions, helping users accurately and quickly find the correct tools and improve training efficiency.

[0009] Furthermore, the three syringes are 10ml syringes, 5ml syringes, and 2ml syringes, respectively.

[0010] The above technical solutions can simulate the diverse instrument selection requirements in actual treatment to meet different injection volume needs, address different situations in actual treatment, and improve the diversity of the training environment.

[0011] Furthermore, the interior of the hemispherical silicone model body has several hollow accommodating spaces, each located at a different depth inward from the surface of the hemispherical silicone model body. The bottom of each hollow accommodating space penetrates the bottom of the hemispherical silicone model body and has a through hole. The bottom sidewall of the through hole has a step. The shapes of the hollow accommodating spaces and the through holes are adapted to the shape of the capsule model. Furthermore, the cyst model includes a cyst tube, the top of which is connected to a cyst cavity, and a valve body is installed at the end of the cyst tube.

[0012] Through the above technical solution, during training, the outer surface of the hemispherical silicone model represents the skin surface, and the depth of the hollow accommodating space from the surface simulates the different depths of cystic lymphangiomas in the human body. Although it does not simulate the specific structure of the human body, it can serve as a simulation training tool for sclerotherapy scenarios of lymphangiomas of different sizes and at different depths below the outer layer of the skin. After inserting the cyst cavity into the corresponding hollow accommodating space, the valve on the cyst tube is opened, and three different colored pigments are poured into the corresponding cyst cavities before closing the valve. The cyst cavity is made of medical soft silicone with a thickness of 2-3 mm (this thickness of soft silicone ensures that it can be repeatedly punctured without leakage, and the cyst can be replaced if leakage occurs after multiple uses). When the scalp needle is punctured into the cyst cavity, it ensures that the liquid inside the cyst cavity will not leak from the puncture site.

[0013] Furthermore, the side wall of the elastic block is provided with several arc-shaped slots of different sizes, which are adapted to the shape and size of different models of syringes, and the top of the arc-shaped slots is an inverted V-shaped opening.

[0014] With the above technical solution, when storing the syringe, place the syringe on the inverted V-shaped opening of the arc-shaped slot corresponding to its model, and then press the syringe downward with the guide of the inclined surface of the inverted V-shaped opening. The elastic block helps the syringe to be inserted into the arc-shaped slot, thus completing the limited storage and convenient access. The syringe placement slot fully limits the syringe and prevents it from slipping.

[0015] Furthermore, the inner walls of both the model body placement slot and the capsule model placement slot are provided with movable slots.

[0016] The above technical solution provides space for users to reach into the placement slot to remove the hemispherical silicone model body and capsule model, making it convenient for users to operate quickly.

[0017] Furthermore, the top of the sterile package is connected to a lid via a zipper, and a handle is fixedly connected to the outer side wall of the sterile package.

[0018] The above technical solutions make the entire kit portable and resealable, maintaining a sterile environment. The handle makes it easy to carry, and the zipper ensures that the internal items will not fall out after closing, making it suitable for use in medical environments.

[0019] Furthermore, three slots are provided for each of the following: a slot for placing simulated lymph fluid bottles, a slot for placing cyst models, and a slot for placing scalp needles; these slots are used to place simulated lymph fluid of different colors; and to place cysts of different sizes and models, as well as scalp needles of different lengths and thicknesses.

[0020] The beneficial effects of this invention are as follows: (1) The hemispherical silicone model body, syringe, lymphatic simulation liquid bottle, cyst model and scalp needle set up are conducive to students’ intuitive learning of how to observe the location and size of lymphangioma under B-ultrasound guidance, judge and select the corresponding syringe and scalp needle, and insert the matching scalp needle into the corresponding cyst model to simulate the injection of the corresponding lymphangioma, and extract different colored lymphatic simulation liquid from the cyst, and observe the process of injecting a certain amount of liquid into the cyst model by using the lymphatic simulation liquid in the syringe as a simulated injection of sclerosing agent, which is conducive to students’ familiarity with and quick mastery of lymphangioma sclerosing treatment technology. (2) By setting up support plates, labels and elastic blocks, it is easy to quickly identify different types of tools, while also making each tool neatly stored and more accurate and convenient to operate.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] like Figure 1 - Figure 7 As shown in the figure, a training model kit for simulated sclerotherapy of lymphangioma under ultrasound guidance in this embodiment includes a sterile package 1. A support plate 4 is placed inside the sterile package 1. The upper end of the support plate 4 is provided with a model body placement slot 401, a syringe placement slot 402, a lymphatic simulation liquid bottle placement slot 403, a cyst model placement slot 404, and a scalp needle placement slot 405. There are three lymphatic simulation liquid bottle placement slots 403, three cyst model placement slots 404, and three scalp needle placement slots 405.

[0025] The model body placement slot 401 contains a hemispherical silicone model body 5 for lymphangioma treatment training. The syringe placement slot 402 has an elastic block 11 fixedly connected inside, and three syringes of different sizes are engaged and connected inside the elastic block 11. The three cyst model placement slots 404 each contain a corresponding cyst model 8 of different sizes simulating lymphangioma. The three scalp needle placement slots 405 each contain a scalp needle 9 of different sizes, with an outer diameter of 0.6mm to 2mm. The three lymphatic simulation liquid bottle placement slots 403 each contain a lymphatic simulation liquid bottle 7 of different colors. The colors of the liquids in the three lymphatic simulation liquid bottles 7 are light red pigment water, light yellow pigment water, and dark red pigment water, respectively, simulating the colors of different lymphatic fluids, and also serving as different colors to distinguish the simulated sclerosing agents for easy observation and identification by the trainee.

[0026] The top of the sterile pack 1 is connected to the cover 2 via a zipper 3. The outer wall of the sterile pack 1 is fixedly connected to a handle 101, which makes the whole set easy to carry and airtight, maintaining a sterile environment. The handle 101 makes it easy to carry the sterile pack 1, and the zipper 3 ensures that the internal items will not fall out after closing, making it suitable for use in a medical environment.

[0027] Several labels 10 are affixed to the upper surface of the support plate 4. The labels 10 correspond to the positions of the syringe 6, scalp needle 9, and lymphatic simulated liquid bottle 7, respectively. The labels 10 can quickly identify different models of syringes 6, scalp needles 9, and lymphatic simulated liquid bottles 7 of different colors, which can help users quickly identify and avoid confusion. Especially during intense training, it can help users accurately and quickly find the correct tools and improve training efficiency.

[0028] The three syringes 6 are 10ml syringes, 5ml syringes and 2ml syringes respectively, which correspond to different injection volume requirements or the extraction of liquid from different capsule models 8, to simulate the diverse instrument selection needs in actual treatment, to deal with different situations in actual treatment, and to improve the diversity of the training environment.

[0029] The hemispherical silicone model body 5 is 3D printed. The interior of the hemispherical silicone model body 5 has three hollow accommodating spaces 501, located at different depths from the surface of the hemispherical silicone model body 5. A through hole 502 is formed at the bottom of each hollow accommodating space 501, penetrating the bottom of the hemispherical silicone model body 5. A step is formed on the bottom sidewall of the through hole 502. The shapes of the hollow accommodating spaces 501 and the through hole 502 are adapted to the shape of the capsule model 8. During training, each capsule model 8 is inserted into its corresponding hollow accommodating space 501 and through hole 502, and the capsule model... The bottom of type 8 is located in the stepped area and is higher than the bottom surface of the hemispherical silicone model body 5, so that the training model body is placed stably. The outer surface of the hemispherical silicone model body 5 represents the simulated skin surface. The depth of the hollow accommodating space 501 from the surface simulates several common depths of cystic lymphangiomas in the human body. Although it does not simulate the structure of specific parts of the human body, it can play a role in simulating the sclerotherapy scenario of lymphangiomas of different sizes and different depths below the outer skin layer. Moreover, the 3D printed silicone model body is not only low in cost, but can also be punctured repeatedly, improving resource utilization.

[0030] The cyst model 8 includes a cyst tube 801, with a cyst cavity 802 connected to the top of the cyst tube 801. A valve body 803 is installed at the end of the cyst tube 801. After inserting the cyst cavity 802 into the corresponding hollow accommodating space 501, the valve body 803 on the cyst tube 801 is opened, and three different colored pigment liquids are poured into the corresponding cyst cavities 802. Then the valve body 803 is closed. The cyst cavity 802 is made of medical soft silicone with a thickness of 2-3 mm and can be repeatedly punctured (it is recommended to perform up to 10 punctures at different needle holes). It can be replaced if leakage occurs. When the scalp needle 9 is punctured into the cyst cavity 802, it can ensure that the liquid in the cyst cavity 802 will not leak from the puncture site. During the operation, the cyst simulating a lymphangioma is located under ultrasound guidance. The size and location of the cyst 802 are determined, and a suitable syringe 6 and scalp needle 9 are selected accordingly. After selecting the appropriate scalp needle 9, it is inserted into the corresponding cyst 802 under ultrasound guidance, and simulated lymphatic fluid is aspirated. After the fluid is aspirated, the cyst 802 contracts, and the color of the fluid in the syringe 6 can be observed. Then, a certain amount of the fluid is injected into the cyst 802 through the syringe 6 as a training exercise simulating the injection of a sclerosing agent. The excess fluid in the syringe 6 is recycled and reused by injecting it into a lymphatic simulation fluid bottle 7 of the corresponding color. The fluid in the cyst 802 is recycled into the lymphatic simulation fluid bottle 7 of the corresponding color by opening the valve body 803, thereby improving resource utilization and avoiding resource waste.

[0031] The side wall of the elastic block 11 has three arc-shaped slots 1101. The three arc-shaped slots 1101 of different sizes are adapted to the shape and size of three different models of syringes 6. The top of the arc-shaped slot 1101 is an inverted V-shaped opening 1102. When storing the syringe 6, the syringe 6 is placed on the inverted V-shaped opening 1102 of the arc-shaped slot 1101 corresponding to its model. Then, with the guide of the inclined surface of the inverted V-shaped opening 1102, the syringe 6 is pressed down. The elastic block 11's toughness helps the syringe 6 to be inserted into the arc-shaped slot 1101, thus completing the limited storage and convenient access. The syringe placement slot 402 fully limits the syringe 6 and prevents the syringe 6 from slipping.

[0032] The inner walls of the model body placement slot 401 and the capsule model placement slot 404 are both provided with movable slots 406. The movable slots 406 provide space for the user to reach into the placement slots to take out the hemispherical silicone model body 5 and the capsule model, which facilitates quick operation by the user.

[0033] The working principle of this embodiment is as follows: When in use, unzip 3 to take out each tool, then insert each type of capsule model 8 into the corresponding hollow accommodating space 501 and through hole 502, insert the capsule cavity 802 into the corresponding hollow accommodating space 501, open the valve body 803 on the capsule tube 801, pour three different colored pigments into the corresponding capsule cavity 802, and then close the valve body 803.

[0034] During the operation, under ultrasound guidance, the simulated lymphangioma cyst 802 is located, and its size and location are determined. Based on this, a suitable syringe 6 and scalp needle 9 are selected. After selecting the appropriate scalp needle 9, it is inserted into the corresponding cyst 802 under ultrasound guidance, and fluid is aspirated. After aspiration, the cyst 802 contracts, and the color of the simulated lymphatic fluid in the syringe 6 is observed. Then, a certain amount of this fluid is injected into the cyst 802 through the syringe 6 as a training exercise simulating sclerotherapy. Excess fluid in the syringe 6 is recycled and reused by injecting it into a simulated lymphatic fluid bottle 7 of the corresponding color. The fluid in the cyst 802 is then recycled into the simulated lymphatic fluid bottle 7 of the corresponding color by opening the valve 803, improving resource utilization and avoiding waste.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
