Description

Technical Field

[0001] The present invention relates to the field of injection training models, in particular to a facial model for injection training in cosmetic surgery. Background Art

[0002] With the development of the medical aesthetics industry, more and more people are adjusting their facial contours to improve facial flaws. However, facial adjustments require high surgical precision, and any slight difference will affect the final adjustment effect. Therefore, such projects have high requirements for the proficiency of the performers. However, the relevant facial injection training models currently available on the market are often only able to provide targeted training for certain locations, and cannot obtain timely feedback on the appearance or pressure changes of the location under use. As a result, the overall training effect is poor and cannot meet existing usage needs. Summary of the Invention

[0003] The purpose of the present invention is to provide a facial model for cosmetic surgery injection training, which solves the technical problems in the prior art that injection changes cannot be fully fed back and the overall training effect is poor, and achieves the technical effect of fully feeding back changes in skin and muscle state during injection and improving the overall training effect.

[0004] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0005] A facial model for cosmetic surgery injection training includes a skull and simulated skin. The front area of ​​the skull is marked with injection point area markers. The frontal bone, temporal bone, and masseter muscle of the skull are located as upper fascia injection points. The frontal bone, temporal bone, zygomatic bone, and mandibular bone of the skull are located as bone surface injection points. Both sides of the nasal bridge of the skull are subdermal injection points. The simulated skin is tightly fitted and covers the outside of the skull. The simulated skin includes a skin layer, superficial muscle fascia, and deep fascia. The skin layer is located on the side away from the skull, and there is a shallow layer of fat between the skin layer and the superficial muscle fascia. There is an upper periosteum between the superficial muscle fascia and the deep fascia. The upper periosteum is made of silicone and is used to support the overall appearance.

[0006] As an improvement, the skin layer and the superficial fat are made of soft silicone, the thickness of the skin layer is greater than the thickness of the superficial fat, and the skin layer and the superficial fat fit tightly together.

[0007] As an improvement, the superficial muscle fascia is made of hard silicone and has multiple sets of pressure sensors inside. The pressure sensors are set around the injection point area marker and can sense and quantify the corresponding data through the pressure changes in the regional position.

[0008] As an improvement, the interior of the superficial muscle fascia has a channel arranged longitudinally with the skin layer, and the channel can form a water storage space with the superficial fat and the upper layer of the periosteum. One end of the upper layer of the periosteum has a channel, and one end of the skull has a control valve. The control valve is connected to the channel of the upper layer of the periosteum for draining the internal water.

[0009] As an improvement, there is a pulling line between the skin layer and the superficial muscle fascia, and the pulling line is arranged around the water storage space. The inside of the skin layer is provided with a slide for sliding with the pulling line.

[0010] As an improvement, the side of the superficial muscle fascia close to the skull is provided with an artery simulation blood vessel, which is the facial artery and the superficial temporal artery. The artery simulation blood vessel is a rubber hose, and the end of the artery simulation blood vessel is provided with a bifurcated tube, which is covered on the upper layer of the periosteum. One end of the artery simulation blood vessel extends out of the skull and is connected to a pump for simulating a pulsation effect.

[0011] The beneficial effects of the present invention are as follows: by setting the skull and each injection point area marker, it is convenient for the operator to find the corresponding injection position; by setting structures such as the skin layer and superficial fat, the skin touch can be better simulated; by cooperating with the superficial muscle fascia structure, the corresponding blood vessel path can be simulated; at the same time, by cooperating with the sensor, the injection situation can be better fed back visually and in data; by setting the arterial simulation blood vessel, the arterial effect can be conveniently simulated, thereby further improving the overall teaching quality.

[0018] like Figures 1 to 3 A facial model for cosmetic surgery injection training is shown, comprising a skull 1 and simulated skin. The frontal area of ​​the skull 1 is marked with injection point markers. The frontal, temporal, zygomatic, and mandibular bones of the skull 1 serve as suprafascial injection points 2. The frontal, temporal, zygomatic, and mandibular bones of the skull 1 serve as bony surface injection points 4. Subdermal injection points 3 are located on either side of the nasal bridge. The simulated skin is fitted snugly over the outside of the skull 1 and comprises a skin layer 5, superficial myofascia 7, and deep fascia 9. The skin layer 5 is located on the side away from the skull 1, with a superficial layer of fat 6 between it and the superficial myofascia 7. Between the superficial myofascia 7 and the deep fascia 9 lies an upper periosteum 8, made of silicone, which supports the overall shape. The lower end of the skull 1 can be fitted with a base containing a control module. A lamp holder is located between the skull 1 and the simulated skin, illuminating the underlying layer of the simulated skin to facilitate observation by trainees.

[0019] The skin layer 5 and superficial fat layer 6 are made of soft silicone. The thickness of the skin layer 5 is greater than that of the superficial fat layer 6, and the skin layer 5 and superficial fat layer 6 are tightly fitted. The superficial muscle fascia 7 is made of hard silicone and contains multiple sets of pressure sensors. These pressure sensors are positioned around the injection point area and can sense and quantify pressure changes in the area to generate corresponding data. This sensor data is transmitted back to the terminal via a data line and integrated into specific data based on the pressure changes, facilitating personnel's judgment.

[0020] The interior of the superficial muscle fascia 7 is provided with a channel arranged longitudinally with the skin layer 5. The channel can form a water storage space with the superficial fat 6 and the upper layer of the periosteum 8. One end of the upper layer of the periosteum 8 is provided with a channel. One end of the skull 1 is provided with a control valve. The control valve is connected to the channel of the upper layer of the periosteum 8 for draining the internal water. A pulling line 10 is provided between the skin layer 5 and the superficial muscle fascia 7. The pulling line 10 is arranged around the water storage space. The interior of the skin layer 5 is provided with a slide for sliding with the pulling line 10. The side of the superficial muscle fascia 7 close to the skull 1 is provided with an artery simulation blood vessel. The artery simulation blood vessel is the facial artery and the superficial temporal artery. The artery simulation blood vessel is a rubber hose. The end of the artery simulation blood vessel is provided with a bifurcated tube. The bifurcated tube covers the upper layer of the periosteum 8. One end of the artery simulation blood vessel extends out of the skull 1 and is connected to a pump for simulating an arterial effect. The facial artery originates from the external carotid artery, passes through the mandibular notch at the front edge of the masseter muscle, about halfway down the lower edge of the mandible, and then enters the face. It then runs along the front of the mandibular body about one finger width away, then diagonally inward and upward, crossing the surface of the masseter muscle, passing the outer corner of the mouth, and ascending along the outer edge of the nose to become the angular artery at the inner canthus. The superficial temporal artery enters from the mandibular angle, about 1.5 cm in front of the ear, and then branches upward into two branches, passing through the temple. It then turns horizontally 1.5 cm above the eyebrow, passing through the eyebrow and entering the inner canthus.

[0021] When in use, after connecting the corresponding pipes and lines, place the device flat on the table, and then use a syringe to perform subcutaneous injection at the corresponding position. At this time, when the needle reaches the predetermined injection position and depth, the superficial muscle fascia 7 will be injected with water, and the water storage space will expand accordingly. At this time, the skin layer 5 will bulge according to the volume change of the water storage space, thereby simulating the corresponding injection effect; in this process, the sensor of the superficial muscle fascia 7 will sense the corresponding pressure change and convert it into a corresponding data signal. At this time, the trainer can judge the corresponding injection status according to the data content, so as to better feedback the current training effect.

[0022] When maintenance is performed, excess moisture in the simulated skin can be discharged through the control valve, thereby restoring the simulated skin to its original state for subsequent recycling.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
