Description

Technical Field

[0001] The present invention relates to the field of medical technology, and particularly to a method for treating with ultra-pulsed shock waves based on facial partitioning. Background Art

[0002] Currently, there are mainly two methods for facial fat bulges:

[0003] 1. Surgery mainly has problems such as large wound surfaces, slow recovery, and work delays.

[0004] 2. Non-invasive radio frequency and ultrasound mainly work on the principle of thermal effect. However, due to problems such as thermal damage and pain, it is easy to cause interruption of the treatment continuity.

[0005] For the above reasons, ultra-pulsed shock wave technology has received favor. However, when using ultra-pulsed shock waves to treat facial fat bulges, no appropriate shock plan is made according to facial features, resulting in poor treatment effects and unable to achieve the effects of a thin, firm, and lifted face. Summary of the Invention

[0006] The present invention provides a method for treating with ultra-pulsed shock waves based on facial partitioning, including the following steps:

[0007] S1. Obtain the facial contour of the face to be reshaped, and extract the feature lines of the facial contour;

[0008] S2. According to the feature lines, divide the facial contour into multiple areas to be repaired;

[0009] S3. Extract the feature points and depressions in the areas to be repaired, and mark the feature points and depressions respectively;

[0010] S4. Process the feature points with the first ultra-pulsed parameters, and process the areas to be repaired except for the feature points and depressions with the second ultra-pulsed parameters.

[0011] In a possible implementation manner, the obtaining the facial contour of the face to be reshaped and extracting the feature lines of the facial contour includes:

[0012] Obtain the three-dimensional image of the facial contour, determine the positions of the feature lines according to the facial feature information stored in the database, and extract the feature lines of the facial contour according to the positions of the feature lines.

[0013] In a possible implementation manner, the dividing the facial contour into multiple areas to be repaired according to the feature lines includes:

[0014] Obtain the positions of the mandibular margin line, the connecting line of the oral commissure axis points, the horizontal line of the cricoid cartilage, and the alar tragus connecting line. Based on the above positions, determine three regions to be repaired, namely the upper, middle, and lower regions.

[0015] In a possible implementation manner, extracting the feature points and depressions in the region to be repaired and separately marking the feature points and depressions includes:

[0016] Obtain the facial height of each point in the region to be repaired. If the facial height is greater than the upper limit of the preset error range, then this point is the feature point; if the facial height is less than the lower limit of the preset error range, then this point is the depression.

[0017] In a possible implementation manner, processing the feature points with the first ultra-pulse parameter and processing the region to be repaired except for the feature points and depressions with the second ultra-pulse parameter includes:

[0018] Determine the first ultra-pulse parameter according to the positions and heights of the feature points, and impact each of the feature points point by point with the first ultra-pulse parameter;

[0019] Adjust the first ultra-pulse parameter to the second ultra-pulse parameter, and impact the part except for the feature points and depressions from bottom to top with the second ultra-pulse parameter.

[0020] In a possible implementation manner, after step S4, it further includes:

[0021] Impact the feature points with the third ultra-pulse parameter, and then impact the other regions except for the feature points and depressions with the fourth ultra-pulse parameter.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] By effectively partitioning the face and identifying the feature points, use strong-intensity pulses to repair the feature points, and use ordinary pulses to repair the non-feature points. Through shock waves, acoustic pore effects, mechanical effects, cavitation effects, etc., it can promote local blood circulation, activate muscles and connective tissues, stimulate collagen regeneration, reduce the quantity and volume of fat, and restore the activity and suspension force of the fascia. Description of the Drawings

[0024] Figure 1 It is a schematic flow chart of the ultra-pulse shock wave processing method based on face partitioning of the present invention. Detailed Embodiments

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts fall within the scope of protection of the present invention.

[0026] It should be noted that the serial numbers assigned to the components in the embodiments of the present invention itself, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings.

[0027] The present invention provides a method for treating with a high-intensity focused shock wave based on facial partitioning, including the following steps:

[0028] S1. Obtain the facial contour of the face to be reshaped, and extract the feature lines of the facial contour;

[0029] S2. Divide the facial contour into multiple regions to be repaired according to the feature lines;

[0030] S3. Extract the feature points and depressions in the regions to be repaired, and mark the feature points and depressions separately;

[0031] S4. Treat the feature points with the first high-intensity focused shock wave parameters, and treat the regions to be repaired except the feature points and depressions with the second high-intensity focused shock wave parameters.

[0032] The high-intensity focused shock wave mainly utilizes a divergent shock wave and applies the "high-intensity focused conversion core technology" to generate a high-energy, high-frequency, and stable compressed gas to drive the bullet body, and outputs high-intensity focused shock wave energy with a pulse width ≤ 20 μm. Through shock wave, acoustic pore effect, mechanical effect, cavitation effect, etc., it can promote local blood circulation, activate muscles and connective tissues, stimulate collagen regeneration, reduce the number and volume of fat, and restore the activity and suspension force of the fascia. Different handpieces are used to act on different facial soft tissue layers, and fixed-point positioning treatment is carried out in a partitioned, layered, and demand-based manner, and then strengthened in combination with the distribution of facial ligaments and superficial fat; then the facial folding degree is improved by using the light, shadow, and gray aesthetic design scheme, and finally the sliding method is used to activate and stabilize the treatment effect and soften the facial curve. Based on this, it is necessary to effectively partition the face to improve the effect of high-intensity focused shock wave.

[0033] Among them, step S1 is carried out in the following manner:

[0034] Obtain the three-dimensional image of the facial contour, determine the position of the feature lines according to the facial feature information stored in the database, and extract the feature lines of the facial contour according to the position of the feature lines.

[0035] According to the characteristic line, the facial contour is divided into a plurality of areas to be repaired, including:

[0036] Obtain the positions of the mandibular margin line, the connecting line of the oral commissure axis points, the horizontal line of the cricoid cartilage, and the connecting line of the alar-nasalis tragus. According to the above positions, determine three areas to be repaired: upper, middle, and lower. The first area is the lower area from the horizontal line of the cricoid cartilage to the lower edge of the mandibular margin line; the second area is the middle area from the upper edge of the mandibular margin line to the connecting line of the oral commissure and the tragus; the third area is the upper area from the connecting line of the alar-nasalis and the upper ear to the connecting line of the oral commissure and the tragus. Different areas can be divided to determine characteristic points in different ways according to the characteristics of different areas (such as from top to bottom, from left to right, etc.), and the positions that need to be strengthened and impacted can be identified more accurately.

[0037] For step S3, the following method can be adopted:

[0038] Obtain the facial height of each point in the area to be repaired. If the facial height is greater than the upper limit of the preset error range, then this point is the characteristic point; if the facial height is less than the lower limit of the preset error range, then this point is the depression.

[0039] For the surface skin of the face, generally the height error is within ±0.5 mm, that is, the error range is [-0.5, 0.5]. For the characteristic points, the height error from them to the other points is greater than 0.5, while for the depressions, the error from them to the other points is less than -0.5. For the present invention, the characteristic points represent fat bulges or softening, and these points need to be focused on and impacted by the ultra-pulse. The depressions are the parts where ultra-pulse impact cannot be carried out. When performing ultra-pulse impact, the depression areas need to be avoided to prevent unnecessary damage.

[0040] When performing ultra-pulse treatment on the facial skin, the following method can be specifically adopted:

[0041] According to the positions and heights of the characteristic points, determine the first ultra-pulse parameters, and impact each of the characteristic points point by point with the first ultra-pulse parameters;

[0042] Adjust the first ultra-pulse parameters to the second ultra-pulse parameters, and impact the parts except the characteristic points and depressions from bottom to top with the second ultra-pulse parameters.

[0043] If the height of the fat bulge or softening is high, the first ultra-pulse parameters are high, the impact pressure is large, and the frequency is high; conversely, if the height of the fat bulge or softening is low, the first ultra-pulse parameters are low, the impact pressure is small, and the frequency is low.

[0044] Furthermore, after step S4, it further includes:

[0045] Impact the feature points with the third super-pulse parameters, and then impact other areas except the feature points and the depressions with the fourth super-pulse parameters. The third super-pulse parameters can be the same as the first super-pulse parameters to perform secondary processing on the feature points, and the fourth super-pulse parameters are used for auxiliary processing of the remaining areas.

[0046] For each of the above parameters, an example will be given in an embodiment as follows:

[0047] First, connect a 15-mm handpiece and use the first super-pulse parameters: 2.0 - 3.0 Bar, 3.0 - 3.5 Hz. First, perform fixed-point processing from bottom to top, with 30 - 50 shots overlapping at each feature point, and then move upward and evenly distribute to each area; then use the second super-pulse parameters: 2.0 - 3.0 Bar, 3.0 - 3.5 Hz to strengthen and fix the ligament areas (gray areas) such as the zygomatic arch ligament and the masseteric cutaneous ligament; then strengthen the anterior face (light area), that is, the cheek and oral commissure pouch areas, of the levator labii alaeque nasi muscle, levator labii muscle, zygomatic minor muscle, and zygomatic major muscle.

[0048] Then connect a 20-mm handpiece and use the third super-pulse parameters: 2.0 - 3.0 Bar, 3.0 - 3.5 Hz. Similarly, first perform fixed-point processing from bottom to top, with 30 - 50 shots overlapping at each point, avoid the depression area, and move upward to each area; then strengthen the double chin, oral commissure pouch, and nasolabial fold (light area); finally, use the fourth super-pulse parameters: 2.0 - 2.5 Bar, 5 - 8 Hz to slide from the inner lower to the outer upper in the lateral face (shadow area) for activation.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
