Therefore, the simulated tissue made from the silicone of this application can replace the real human body for fascia relaxation or other medical training, avoiding the safety risks of harm to the real human body. Furthermore, since the main components of the silicone used in this application are all non-irritating, non-toxic, and non-allergenic materials, when the simulated tissue made from this silicone is used for medical simulation training, even if the trainee's human tissue, such as skin, comes into direct contact with the simulated tissue, it will not harm the human tissue, thus improving safety.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] This application provides a method for preparing silicone for a simulator of beryllium needles, needle knives, and blade needles used in minimally invasive acupuncture and myofascial release procedures. Figure 1 As shown, it includes the following steps:

[0024] Step 101: Obtain the first material and the second material.

[0025] Obtain a first material and a second material. The components of the first material, by mass parts, include 40-120 parts of vinyl-terminated silicone oil, 10-50 parts of fumed silica, 1-50 parts of dimethyl silicone oil, 0.01-5 parts of platinum catalyst, and 0.02-3 parts of inhibitor.

[0026] The second material comprises, by mass parts, 40-120 parts of vinyl-terminated silicone oil, 10-70 parts of fumed silica, 1-50 parts of dimethyl silicone oil, 4-100 parts of hydrogen-containing silicone oil, 0-5 parts of color masterbatch, and 0.02-3 parts of inhibitor.

[0027] Vinyl-terminated silicone oil is used as the base polymer. Fumed silica, also known as fumed carbon black, is used as a reinforcing agent to enhance the viscoelastic properties and surface hardness of silicone. Dimethyl silicone oil is used as a diluent; by adjusting its viscosity and dosage, the crosslinking density of the molded material can be controlled, thus making the hardness of the silicone more closely resemble that of real human tissue. Platinum catalysts are used to catalyze the reaction of vinyl-terminated silicone oil, fumed silica, and dimethyl silicone oil, increasing the reaction rate. Inhibitors are used to complex with the platinum catalyst, reducing its activity and thus lowering the reaction rate. Hydrogen-containing silicone oil is used for crosslinking molding. Masterbatch is used for dyeing.

[0028] In this embodiment, the viscosity of the vinyl-terminated silicone oil is 400 mPa·s-9000 mPa·s, and the specific surface area of ​​the fumed silica is 100-400 m² / s. 2 / g, the viscosity of dimethyl silicone oil is 50 mPa·s-1000 mPa·s. It should be noted that the higher the viscosity of vinyl-terminated silicone oil and dimethyl silicone oil, the easier the material will be to mold; however, properties such as hardness, tensile strength, and tear strength will differ from those of human tissues such as skin, fat, fascia, and muscle, failing to achieve a realistic simulation. Conversely, if the viscosity of vinyl-terminated silicone oil and dimethyl silicone oil is too low, the material will be difficult to mold. Therefore, a viscosity of 400 mPa·s-9000 mPa·s for vinyl-terminated silicone oil and 50 mPa·s-1000 mPa·s for dimethyl silicone oil ensures both simulation accuracy and improved production efficiency. Similarly, the specific surface area of ​​fumed silica is 100-400 m² / g. 2 At a rate of / g, the properties of the simulated material can be made close to those of real human tissue.

[0029] Step 102: Knead and mix the first material to obtain the base rubber.

[0030] Step 103: Knead and mix the second material to obtain a curing agent.

[0031] In steps 102 and 103, the first material and the second material are kneaded and mixed, respectively. Kneading and mixing can make other materials uniformly dispersed in the base polymer, thereby making the composition and properties of each part of the base glue and curing agent uniform and consistent.

[0032] Furthermore, processing the first and second materials separately is to balance the processability of material handling and molding. If the first and second materials are not kneaded and mixed to obtain a base adhesive and curing agent with uniform property distribution, but are instead directly mixed, the two materials will react at room temperature and vulcanize in a short time. In this case, the operability of production and processing is poor, it is impossible to perform heat molding as intended, and vulcanization may also contaminate the mold used for heat molding. Therefore, processing the first and second materials separately not only improves the operability of the production process, but also avoids contamination of some equipment, reduces costs, and is more environmentally friendly.

[0033] Step 104: Mix the base adhesive and the curing agent, stir evenly, and heat to form in a first temperature range to obtain silicone. The first temperature range is 80℃-120℃.

[0034] In this step, the base adhesive and curing agent are mixed in a 1:1 ratio and stirred evenly. After heating and molding, a human body composition simulation material is obtained. It should be noted that after the base adhesive and curing agent are mixed together, the presence of inhibitors reduces the catalytic rate of the catalyst after reacting with the platinum catalyst, thereby delaying the curing time of the base adhesive and curing agent. This allows sufficient time for stirring the mixture of base adhesive and curing agent and for pouring the mixture into the mold for heating and molding.

[0035] The silicone prepared through the above steps has a Shore A hardness in the range of 0HA-65HA. The Shore A hardness of human skin, fat, fascia, and muscle falls within the selectable Shore A hardness range of the silicone in this application. It can be understood that the Shore A hardness of the obtained silicone can be adjusted by changing the amount and viscosity of each component in the silicone to achieve the purpose of simulating human tissue. Therefore, the silicone used in this application to make simulated tissue can replace the real human body for fascia relaxation or other medical training, avoiding the safety risks of harm to the real human body. Furthermore, since the main components of the silicone used in this application are all non-irritating, non-toxic, and non-allergenic materials, when the simulated tissue made from this silicone is used for medical simulation training, even if the trainee's human tissue, such as skin, comes into direct contact with the simulated tissue, it will not harm the trainee, thus improving safety.

[0036] Optionally, the kneading and mixing of the first material to obtain the base rubber includes:

[0037] The first material is added to a kneader and kneaded in a second temperature range and a first pressure range to obtain a first intermediate material. The second temperature range is 60℃-80℃ and the first pressure range is 0.1MPa-0.2MPa.

[0038] The first intermediate material is added to a mixer and mixed to obtain the base rubber.

[0039] In this embodiment, the components are added sequentially to a kneader according to the proportion of the first material. Preferably, kneading is carried out at a temperature of 60°C and a pressure of 0.1 MPa for 3-4 hours. The material is then removed and placed into a three-roll mill for mixing to obtain the base rubber. It should be noted that higher temperatures and pressures result in faster kneading of the components of the first material, but correspondingly, the uniformity of the base rubber and the product quality will be worse. Under conditions of 60°C-80°C and 0.1 MPa-0.2 MPa, both the quality of the base rubber and the production rate are guaranteed.

[0040] Optionally, the kneading and mixing of the second material to obtain a curing agent includes:

[0041] The second material is added to a kneader and kneaded in a second temperature range and a first pressure range to obtain a second intermediate material. The second temperature range is 60℃-80℃ and the first pressure range is 0.1MPa-0.2MPa.

[0042] The second intermediate material is added to a mixer and mixed to obtain the curing agent.

[0043] Similar to the above embodiments, the second material is kneaded under conditions of 60℃-80℃ and 0.1MPa-0.2MPa, and after 3-4 hours, the material is taken out and put into a three-roll mill for mixing to obtain a curing agent, which ensures both the quality of the base adhesive and the production rate.

[0044] Optionally, the mixture of the base adhesive and the curing agent, after being stirred evenly, is heated and molded at a temperature of 80-120°C to obtain silicone, comprising:

[0045] The base adhesive and the curing agent are mixed, stirred evenly, and then vacuum degassed. The mixture is then heated and molded in the first temperature range to obtain the silicone.

[0046] In this embodiment, the base adhesive and curing agent are mixed. The inhibitor undergoes a complexation reaction with the platinum catalyst, reducing catalyst activity and slowing down the curing speed of the base adhesive and curing agent. The base adhesive and curing agent are stirred evenly to ensure sufficient reaction of the components; however, stirring inevitably generates air bubbles during this process. Vacuum degassing technology is used to remove air bubbles from the material before heating and molding. The resulting silicone will not contain voids caused by air bubbles, thus ensuring the uniformity of the silicone.

[0047] Optionally, the inhibitor comprises at least one of the following: 2-methyl-3-butynyl-2-ol, 3-methyl-1-methyl-1-hexynyl-3-ol, tetramethyldivinyldisiloxane, and tetramethyltetravinylcyclosiloxane.

[0048] In this embodiment, the inhibitor is used to undergo a complexation reaction with the platinum catalyst, and there are several options, preferably tetramethyldivinyldisiloxane. Tetramethyldivinyldisiloxane has high chemical stability and heat resistance, and is easy to store.

[0049] like Figure 2 , Figure 3As shown in the illustration, this application also provides a simulator for minimally invasive acupuncture techniques such as beryllium needles, needle knives, and blade needles to release fascia. The simulator includes a base 1, a support plate 2, and a simulated tissue 3. The support plate 2 is rotatably connected to the base, and the simulated tissue 3 is fixed on the support plate 2. The simulated tissue 3 includes a simulated skin layer 31, a simulated fat layer 32, a simulated fascia layer 33, and a simulated muscle layer 34, which are stacked sequentially. The simulated skin layer 31, the simulated fat layer 32, the simulated fascia layer 33, and the simulated muscle layer 34 are all made of silicone as described in the above embodiments. Since the technical solution of this embodiment includes all the technical solutions of the above embodiments, it can at least achieve all the technical effects of the above embodiments, and will not be described in detail here.

[0050] The support plate 2 is rotatably connected to the base 1, and the simulated tissue 3 is fixed on the support plate 2. By adjusting the angle of the support plate 2 relative to the base 1, the height of the support plate 2 can be adjusted, thereby adjusting the height of the simulated tissue 3 to meet the height requirements for different operations.

[0051] In the simulated tissues of this application embodiment, the proportions of silicone used to form the simulated skin layer 31, simulated fat layer 32, simulated fascia layer 33, and simulated muscle layer 34 are different. Preferably, the proportions of the silicone used in each tissue layer are as follows:

[0052] The silicone material used to make the simulated skin layer 31 comprises, by mass parts, 90-110 parts of vinyl-terminated silicone oil with a viscosity of 7500-8500 mPa·s, 45-55 parts of fumed silica, 25-35 parts of dimethyl silicone oil with a viscosity of 150-250 mPa·s, 0.2 parts of platinum catalyst, and 0.1 parts of inhibitor. The silicone material used to make the simulated skin layer 31 comprises, by mass parts, 90-110 parts of vinyl-terminated silicone oil with a viscosity of 7500-8500 mPa·s, 45-55 parts of fumed silica, 25-35 parts of dimethyl silicone oil with a viscosity of 150-250 mPa·s, 5 parts of 0.8% hydrogen-containing silicone oil, 0.1 parts of inhibitor, and 3 parts of color masterbatch.

[0053] The simulated skin layer 31 made using the above-mentioned proportions has a Shore A hardness of approximately 30 HA.

[0054] The silicone material used to form the simulated fat layer 32 comprises, by mass parts, 90-110 parts of vinyl-terminated silicone oil with a viscosity of 450-550 mPa·s, 15-25 parts of fumed silica, 35-45 parts of dimethyl silicone oil with a viscosity of 80-120 mPa·s, 0.2 parts of platinum catalyst, and 0.1 parts of inhibitor. The silicone material used to form the simulated fat layer 32 comprises, by mass parts, 90-110 parts of vinyl-terminated silicone oil with a viscosity of 450-550 mPa·s, 15-25 parts of fumed silica, 35-45 parts of dimethyl silicone oil with a viscosity of 80-120 mPa·s, 4 parts of 0.4% hydrogen-containing silicone oil, 0.1 parts of inhibitor, and 1 part of color masterbatch.

[0055] The simulated fat layer 32 made using the above-mentioned proportions has a Shore A hardness of approximately 0HA.

[0056] The silicone material used to make the simulated fascia layer 33 comprises, by mass parts, 90-110 parts of vinyl-terminated silicone oil with a viscosity of 5700-6300 mPa·s, 25-35 parts of fumed silica, 25-35 parts of dimethyl silicone oil with a viscosity of 80-120 mPa·s, 0.2 parts of platinum catalyst, and 0.1 parts of inhibitor; the silicone material used to make the simulated fascia layer 33 comprises, by mass parts, 90-110 parts of vinyl-terminated silicone oil with a viscosity of 5700-6300 mPa·s, 55-65 parts of fumed silica, 25-35 parts of dimethyl silicone oil with a viscosity of 80-120 mPa·s, 10 parts of 0.8% hydrogen-containing silicone oil, and 0.1 parts of inhibitor.

[0057] The simulated fascia layer 33 made using the above-mentioned proportions has a Shore A hardness of approximately 60HA.

[0058] The silicone material used to form the simulated muscle layer 34 comprises, by weight parts, 45-55 parts of vinyl-terminated silicone oil with a viscosity of 3500-4500 mPa·s, 45-55 parts of vinyl-terminated silicone oil with a viscosity of 900-1100 mPa·s, 25-35 parts of fumed silica, 15-25 parts of dimethyl silicone oil with a viscosity of 80-120 mPa·s, 0.2 parts of platinum catalyst, and 0.1 parts of inhibitor; the first material in the silicone material used to form the simulated muscle layer 34 comprises, by weight parts, 45-55 parts of vinyl-terminated silicone oil with a viscosity of 900-1100 mPa·s, 25-35 parts of fumed silica, 15-25 parts of dimethyl silicone oil with a viscosity of 80-120 mPa·s, 0.2 parts of platinum catalyst, and 0.1 parts of inhibitor; The silicone of the simulated muscle layer 34 contains the following components by mass parts: 45-55 parts of vinyl-terminated silicone oil with a viscosity of 3500-4500 mPa·s, 45-55 parts of vinyl-terminated silicone oil with a viscosity of 900-1100 mPa·s, 25-35 parts of fumed silica, 15-25 parts of dimethyl silicone oil with a viscosity of 80-120 mPa·s, 40 parts of 0.8% hydrogen-containing silicone oil, 0.1 parts of inhibitor, and 5 parts of color masterbatch.

[0059] The simulated muscle layer 34 made using the above-mentioned proportions has a Shore A hardness of approximately 10HA.

[0060] In this embodiment, the Shore A hardness of the simulated skin layer 31, simulated fat layer 32, simulated fascia layer 33 and simulated muscle layer 34 of the simulated tissue 3 are approximately 30HA, 0HA, 60HA and 10HA respectively, which are close to the Shore A hardness of real human skin tissue, fat tissue, fascia tissue and muscle tissue.

[0061] It should be noted that, in addition to the preferred schemes mentioned above, the Shore A hardness of the simulated skin layer 31 is between 20HA and 40HA, the Shore A hardness of the simulated fat layer 32 is between 0HA and 5HA, the Shore A hardness of the simulated fascia layer 33 is between 55HA and 65HA, and the Shore A hardness of the simulated muscle layer 34 is between 5HA and 15HA, all of which can meet the simulation requirements of real human tissues.

[0062] Furthermore, the color masterbatch in the simulated skin layer 31, simulated fat layer 32, simulated fascia layer 33, and simulated muscle layer 34 is 3 parts, 1 part, 0 parts, and 5 parts, respectively. The more color masterbatch used, the darker the color of the corresponding tissue. Optionally, the color masterbatch contained in the silicone used to make the simulated skin layer 31 is yellow, the color masterbatch contained in the silicone used to make the simulated fat layer 32 is yellow, the color masterbatch contained in the silicone used to make the simulated fascia layer 33 is white, and the color masterbatch contained in the silicone used to make the simulated muscle layer 34 is red.

[0063] The colors of the simulated skin layer 31, simulated fat layer 32, and simulated muscle layer 34 are determined by the color of the masterbatch. The masterbatch can be one or more of the following colors: red, orange, yellow, green, cyan, blue, purple, white, and black. Preferably, the masterbatch in both the simulated skin layer 31 and simulated fat layer 32 is yellow. Since the masterbatch amounts are 3 parts and 1 part respectively, the shades differ, specifically, the simulated skin layer 31 is milky yellow, and the simulated fat layer 32 is pale yellow. No masterbatch is added to the simulated fascia layer 33, therefore, the simulated fascia layer 33 is translucent white. The masterbatch in the simulated muscle layer 34 is red, with 5 parts of masterbatch, resulting in a bright red color for the simulated muscle layer 34.

[0064] In this embodiment, the color contrast between the simulated skin layer 31, simulated fat layer 32, simulated fascia layer 33, and simulated muscle layer 34 is close to the contrast of real human skin, fat, fascia, and muscle, further achieving a simulation effect.

[0065] Optionally, the thickness of the simulated skin layer 31 is 0.2-2 mm, the thickness of the simulated fat layer 32 is 1-12 mm, the thickness of the simulated fascia layer 33 is 0.2-1 mm, and the thickness of the simulated muscle layer 34 is 2-9 mm.

[0066] In this embodiment, the thickness ratio between the simulated skin layer 31, simulated fat layer 32, simulated fascia layer 33, and simulated muscle layer 34 is close to the thickness ratio of the real human body. Preferably, the thickness of the simulated skin layer 31 is 1 mm, the thickness of the simulated fat layer 32 is 6 mm, the thickness of the simulated fascia layer 33 is 0.4 mm, and the thickness of the simulated muscle layer 34 is 8 mm, which further improves the simulation effect of the simulated tissue in this embodiment.

[0067] Furthermore, the simulated skin layer 31, simulated fat layer 32, simulated fascia layer 33, and simulated muscle layer 34 maintain a consistent shape, which can be rectangular, square, triangular, circular, or elliptical, preferably a rounded square. The area ranges from 5 to 500 square centimeters.

[0068] When using beryllium needles, needle knives, and blade needles for insertion, the simulator exhibits significant resistance in the simulated skin layer 31, virtually no resistance in the simulated fat layer 32, significant resistance in the simulated fascia layer 33, and slight resistance in the simulated muscle layer 34. This creates a characteristic similar to that of the real human body, where there is a noticeable hollowing sensation when piercing the skin layer and a very obvious hollowing sensation when piercing the fascia layer. Learners using this simulator can realistically experience and accurately master the feel of needling different layers and the hollowing sensation of the needle tip penetrating the skin and fascia layers. Practitioners using this simulator can quickly experience and master the key feel and core techniques of these beryllium needle, needle knife, and blade needle minimally invasive acupuncture methods for releasing diseased fascia.

[0069] By using this simulator for training, and continuously adjusting and improving the insertion and fascia release techniques of minimally invasive needles such as beryllium needles, needle knives, and blade needles, one can efficiently and accurately master the key feel and core techniques of releasing diseased fascia with minimally invasive needles such as beryllium needles, needle knives, and blade needles. This allows for thorough puncture of the fascia during fascia release, and immediate stopping of the needle insertion as close as possible to the fascia layer to avoid damaging deep fascial muscles and other tissues, thereby improving the effectiveness and safety of fascia release operations.

[0070] Optionally, the simulator further includes a fixing component, which includes a fixing plate 6 and two threaded connectors 5. The fixing plate 6 has two through holes, and the support plate 2 has two threaded holes. The two threaded connectors 5 pass through the two through holes and are fixed in the two threaded holes respectively. The fixing plate 6 and the support plate 2 are used to clamp the simulated tissue 3.

[0071] Please refer to the above. Figure 2and Figure 3 The fixed plate 6 and the support plate 2 are connected by a threaded connector 5, forming a clamping space between the fixed plate 6, the support plate 2, and the threaded connector. Figure 2 In the embodiment shown, there are two fixing plates 6 and four threaded connectors 5. Two threaded holes are also opened on the base 1 to fix the threaded connectors 5. The four threaded connectors 5, two fixing plates 6, support plate 2 and base 1 form a clamping space for fixing the simulated tissue 3. The structure is simple and easy to disassemble and produce.

[0072] Optionally, the simulator further includes a damping hinge, one end of the support plate 2 is connected to the base 1 through the damping hinge, and the damper fixed point angle of the damping hinge is adjusted to adjust the angle of the support plate 2 relative to the base 1.
