[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] The present application embodiment provides a method for preparing silica gel used in a simulator for minimally invasive acupuncture fascia release operation using a beryllium needle, acupuncture knife, or blade needle, such as Figure 1 As shown, the following steps are included:

[0024] Step 101, obtaining a first material and a second material.

[0025] A first material and a second material are obtained, wherein the first material comprises, by weight, 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 a platinum catalyst, and 0.02-3 parts of an inhibitor.

[0026] The components of the second material, calculated by weight, include 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 hydrogenated silicone oil, 0-5 parts of masterbatch, and 0.02-3 parts of inhibitor.

[0027] Among them, vinyl-terminated silicone oil is used as a base polymer. Fumed silica, also known as fumed silica, 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 the viscosity and dosage of dimethyl silicone oil, the crosslinking density of the material after molding can be adjusted, so that the hardness of the silicone is closer to real human tissue. Platinum catalysts are used to catalyze the reaction of vinyl-terminated silicone oil, fumed silica, and dimethyl silicone oil to increase the reaction rate. Inhibitors are used to react with platinum catalysts to reduce the activity of platinum catalysts, thereby reducing 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 400mPa.s-9000mPa.s, and the specific surface area of ​​the fumed silica is 100-400m 2 / g, the viscosity of dimethyl silicone oil is 50mPa.s-1000mPa.s. It should be noted that the higher the viscosity of terminal vinyl silicone oil and dimethyl silicone oil, the easier the material will be to mold, but the properties such as hardness, tensile strength, and tear strength will be different from the corresponding properties of human tissues such as skin, fat, fascia, and muscle, and the simulation effect cannot be achieved. If the viscosity of terminal vinyl silicone oil and dimethyl silicone oil is too low, the material will be inconvenient to mold. Therefore, when the viscosity of terminal vinyl silicone oil is 400mPa.s-9000mPa.s and the viscosity of dimethyl silicone oil is 50mPa.s-1000mPa.s, the simulation effect is guaranteed and the production efficiency can be improved. Similarly, the specific surface area of ​​fumed silica is 100-400m 2 / g, the properties of the simulated material can be made close to those of real human tissue.

[0029] Step 102, kneading and mixing the first material to obtain a base rubber.

[0030] Step 103: kneading and mixing 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. The kneading and mixing can make the other materials dispersed evenly in the base polymer, so that the composition and performance of each part in the base glue and the curing agent are uniform.

[0032] In addition, the first material and the second material are processed separately in order to take into account the processability of material processing and molding preparation. If the first material and the second material are not kneaded and mixed to obtain a base rubber and a curing agent with uniform property distribution, but the first material and the second material are directly mixed, then the two materials will react at room temperature and vulcanize and form in a relatively short time. In this case, the operability of production and processing is poor, and heating and forming cannot be performed as expected, and vulcanization may also contaminate the mold for heating and forming. Therefore, processing the first material and the second material separately can not only improve the operability in the production and preparation process, but also avoid the pollution of some equipment, reduce costs, and be more environmentally friendly.

[0033] Step 104 , mixing the base glue and the curing agent, stirring them evenly, and then heating and molding them in a first temperature range to obtain silica gel, wherein the first temperature range is 80° C.-120° C.

[0034] In this step, the base glue and the curing agent are mixed and stirred in a ratio of 1:1, and then heated and formed to obtain a human body composition simulation material. It should be noted that after the base glue and the curing agent are mixed together, due to the presence of the inhibitor, after reacting with the platinum catalyst, the catalytic speed of the catalyst is reduced, thereby delaying the curing time of the base glue and the curing agent, so that there is ample time to stir the mixture of the base glue and the curing agent and pour the mixture into the mold for heating and forming.

[0035] The Shore A hardness of the silicone prepared by the above steps is within the range of 0HA-65HA, and the Shore A hardness of human skin, fat, fascia, and muscle is within the range of the selectable Shore A hardness of the silicone of the present application. It can be understood that by adjusting the amount and viscosity of each component in the silicone, the Shore A hardness of the obtained silicone can be adjusted to achieve the purpose of simulating human tissue. Therefore, the simulated tissue made of the silicone of the present application can replace the real human body for fascial relaxation or other medical training, which can avoid the safety risk of harming the real human body. In addition, since the main components of the silicone of the present application are all materials that are non-irritating, non-toxic, and non-allergic to the human body, therefore, when the simulated tissue made of the silicone is used for medical simulation training, even if the human tissue of the practitioner, such as skin, directly contacts the simulated tissue, it will not harm the practitioner, which can improve safety.

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

[0037] Adding the first material into a kneader, kneading in a second temperature range and a first pressure range to obtain a first intermediate material, wherein the second temperature range is 60° C.-80° C., and the first pressure range is 0.1 MPa-0.2 MPa;

[0038] The first intermediate material is added into a mixer for mixing to obtain the base rubber.

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

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

[0041] Adding the second material into a kneader, kneading at a second temperature range and a first pressure range to obtain a second intermediate material, wherein the second temperature range is 60° C.-80° C., and the first pressure range is 0.1 MPa-0.2 MPa;

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

[0043] Similar to the above embodiment, the second material is kneaded at 60°C-80°C 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 rubber and the production rate.

[0044] Optionally, the base glue and the curing agent are mixed, stirred evenly, and then heated at a temperature of 80-120° C. to form a silica gel, comprising:

[0045] The base glue and the curing agent are mixed, stirred evenly and vacuum degassed, and then heated and molded in the first temperature range to obtain the silica gel.

[0046] In this embodiment, the base glue and the curing agent are mixed, wherein the inhibitor reacts with the platinum catalyst to reduce the activity of the catalyst and slow down the curing speed of the base glue and the curing agent. The base glue and the curing agent are stirred evenly so that each component can fully react, but in this process, stirring will inevitably produce bubbles. The vacuum degassing technology is used to remove the bubbles in the material before heating and molding. The resulting silicone will not have a hollow area caused by bubbles, so the uniformity of the silicone can be guaranteed.

[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, tetramethyltetravinylcyclosiloxane.

[0048] In this embodiment, the inhibitor is used for complexing reaction with the platinum catalyst, and there are multiple options, preferably tetramethyldivinyldisiloxane, which has high chemical stability and heat resistance and is easy to store.

[0049] like Figure 2 , Figure 3As shown, the embodiment of the present application also provides a simulator for minimally invasive acupuncture fascia release operation using beryllium needles, needle knives, and blade needles. The simulator includes a base 1, a support plate 2, and 3 simulated tissues. The support plate 2 is rotatably connected to the base, and the simulated tissue 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 stacked in sequence. 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 proposed in the above embodiment. Since the technical solution of this embodiment includes all the technical solutions of the above embodiment, it can at least achieve all the technical effects of the above embodiment, which will not be repeated here one by one.

[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 tissue of the embodiment of the present application, the composition ratio of the silicone used to make each layer of tissue such as the simulated skin layer 31, the simulated fat layer 32, the simulated fascia layer 33 and the simulated muscle layer 34 is different. Preferably, the composition ratio of each layer of tissue is as follows:

[0052] The components of the first material contained in the silicone gel used to make the simulated skin layer 31 are calculated by mass, including 90-110 parts of terminal vinyl silicone oil with a viscosity of 7500-8500mPa.s, 45-55 parts of fumed silica, 25-35 parts of dimethyl silicone oil with a viscosity of 150-250mPa.s, 0.2 parts of platinum catalyst, and 0.1 parts of inhibitor. The components of the second material contained in the silicone gel used to make the simulated skin layer 31 are calculated by mass, including 90-110 parts of terminal vinyl silicone oil with a viscosity of 7500-8500mPa.s, 45-55 parts of fumed silica, 25-35 parts of dimethyl silicone oil with a viscosity of 150-250mPa.s, 5 parts of 0.8% hydrogenated silicone oil, 0.1 parts of inhibitor, and 3 parts of masterbatch.

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

[0054] The components of the first material contained in the silicone gel used to make the simulated fat layer 32 are calculated by mass, including 90-110 parts of terminal vinyl silicone oil with a viscosity of 450-550mPa.s, 15-25 parts of fumed silica, 35-45 parts of dimethyl silicone oil with a viscosity of 80-120mPa.s, 0.2 parts of platinum catalysts, and 0.1 parts of inhibitors. The components of the second material contained in the silicone gel used to make the simulated fat layer 32 are calculated by mass, including 90-110 parts of terminal vinyl silicone oil with a viscosity of 450-550mPa.s, 15-25 parts of fumed silica, 35-45 parts of dimethyl silicone oil with a viscosity of 80-120mPa.s, 4 parts of 0.4% hydrogenated silicone oil, 0.1 parts of inhibitors, and 1 part of masterbatch.

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

[0056] The components of the first material contained in the silicone used to make the simulated fascia layer 33 are calculated by mass, including 90-110 parts of terminal vinyl silicone oil with a viscosity of 5700-6300mPa.s, 25-35 parts of fumed silica, 25-35 parts of dimethyl silicone oil with a viscosity of 80-120mPa.s, 0.2 parts of platinum catalyst, and 0.1 parts of inhibitor; the components of the second material contained in the silicone used to make the simulated fascia layer 33 are calculated by mass, including 90-110 parts of terminal vinyl silicone oil with a viscosity of 5700-6300mPa.s, 55-65 parts of fumed silica, 25-35 parts of dimethyl silicone oil with a viscosity of 80-120mPa.s, 10 parts of 0.8% hydrogenated silicone oil, and 0.1 parts of inhibitor.

[0057] The Shore A hardness of the simulated fascia layer 33 made of the above-mentioned proportion of components is about 60HA.

[0058] The first material contained in the silicone gel used to make the simulated muscle layer 34 comprises, by weight, 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 a platinum catalyst, and 0.1 parts of an inhibitor; The components of the second material contained in the silicone of the simulated muscle layer 34 are calculated by mass, including 45-55 parts of terminal vinyl silicone oil with a viscosity of 3500-4500mPa.s, 45-55 parts of terminal vinyl silicone oil with a viscosity of 900-1100mPa.s, 25-35 parts of fumed silica, 15-25 parts of dimethyl silicone oil with a viscosity of 80-120mPa.s, 40 parts of 0.8% hydrogenated silicone oil, 0.1 parts of inhibitor, and 5 parts of masterbatch.

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

[0060] In the embodiment of the present application, 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 the skin tissue, fat tissue, fascia tissue and muscle tissue of a real human body.

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

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

[0063] The colors of the simulated skin layer 31, the simulated fat layer 32, and the simulated muscle layer 34 are determined by the colors of the masterbatch, which can be one or more of red, orange, yellow, green, cyan, blue, purple, white, and black. Preferably, the colors of the masterbatch contained in the simulated skin layer 31 and the simulated fat layer 32 are both yellow. Since the number of masterbatch portions is 3 and 1 respectively, the color depths of the two are different, which is specifically manifested as "the color of the simulated skin layer 31 is cream yellow, and the color of the simulated fat layer 32 is light yellow". No masterbatch is added to the simulated fascia layer 33, so the color of the simulated fascia layer 33 is translucent white. The color of the masterbatch contained in the simulated muscle layer 34 is red, the number of masterbatch portions is 5, and the color of the simulated muscle layer 34 is bright red.

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

[0067] In addition, the simulated skin layer 31, the simulated fat layer 32, the simulated fascia layer 33 and the simulated muscle layer 34 are in the same shape, which can be a rectangle, a square, a triangle, a circle, an ellipse, preferably a rounded square, with an area of ​​5-500 square centimeters.

[0068] When using beryllium needles, needle knives, and blade needles for minimally invasive needle insertion, the simulator's simulated skin layer 31 has obvious resistance, the simulated fat layer 32 has basically no resistance, the simulated fascia layer 33 has obvious resistance, and the simulated muscle layer 34 has slight resistance, forming a characteristic that is consistent with the real human body, with a more obvious hollow feeling when the skin layer is pierced, and a very obvious hollow feeling when the fascia layer is pierced. When learners use this simulator for training, they can very realistically feel and accurately grasp the feel of needles piercing different levels and the hollow feeling of the needle tip breaking through the skin and fascia layers. Practitioners using this simulator can quickly experience and master the key feel and core technology of these beryllium needles, needle knives, and blade needles for minimally invasive acupuncture to release diseased fascia.

[0069] By training with this simulator, we can continuously adjust and improve the needle insertion and fascia release techniques of beryllium needles, needle knives, and blade needles. We can efficiently and accurately master the key feel and core technology of minimally invasive needle release of diseased fascia with beryllium needles, needle knives, and blade needles, so that the fascia can be completely pierced when release, and the needle insertion should be stopped immediately when the fascia layer is pierced as close as possible to avoid damaging the muscles and other tissues deep in the fascia, thereby improving the effectiveness and safety of fascia release operations.

[0070] Optionally, the simulator also includes a fixing component, which includes a fixing plate 6 and two threaded connectors 5.
