Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the rehabilitation care process of the burned skin by using the micro-peeling type fractional skin changing technology, micro-beam energy of carbon dioxide laser is utilized to vaporize part of subcutaneous tissues, and a plurality of small holes are formed in the skin. The carbon dioxide laser stimulates the skin to produce new, healthier collagen to promote healing. The operation helps repair scar tissue, normalizing its texture and thickness, and the laser improves the elasticity of scar skin and the firmness of the tissue. However, the pain nerves in the skin are not avoided in the above process, so that the patient needs an analgesia pump to continuously pump large doses of analgesic during the treatment process, and the body of the patient is adversely affected.
Referring to fig. 1 to 2, the present invention provides a laser nursing device 1 for skin surgery, which may include a laser generating mechanism 11, a limb fixing mechanism 12, and an epidermis image collecting mechanism 13. The laser generating means 11 can be used to generate a laser spot array. The limb immobilization mechanism 12 may be used to immobilize a patient's limb, maintaining a relatively stable skin surface position and shape. The epidermal image acquisition mechanism 13 may be used to acquire images of the skin surface. In operation of the device, step S1 may be performed to obtain the location distribution of the free nerve endings in the skin according to the image of the skin surface. Step S2 may then be executed to define a skin area to be treated, control the laser generating mechanism 11 to form a laser spot array in the skin according to the position distribution of the free nerve endings in the skin, and keep the laser spot array away from the free nerve endings. By controlling the laser generating mechanism 11 to form a laser spot array in the skin, the microbeam energy formed by the laser spots is vaporized into small holes to avoid free nerve endings for sensing pain, so that the pain of a patient is avoided, the use of narcotics is reduced, and the adverse effect on the body of the patient is avoided.
Referring to fig. 3, in order to accurately obtain the position of the free nerve endings in the skin, the step of obtaining the position distribution of the free nerve endings in the skin according to the image of the skin surface in step S1 may specifically be to first perform step S111 to obtain the color values of the pixel points in the image of the skin surface, and then perform step S112 to extract the contour of the hair color in the image of the skin surface according to the color values of the hair color. Step S113 may be performed next to extract a thin bar-shaped portion in the outline of the hair color in the image, labeled as a body hair region. Step S114 may be performed next to extract the contour of the skin color in the image of the skin surface, labeled as a skin region, according to the color value of the skin color. Step S115 may be performed next to acquire the spatial position of each point of the skin from the skin area. Step S116 may then be performed to mark the body hair region and the skin region as pore regions. Step S117 may be performed next to extract the spatial position of the sweat pores in the skin region from the image features of the sweat pore region. Finally, step S118 may be executed to mark the superficial layer of the skin and the hair follicle in the pore as a free nerve end distribution region, and obtain the position distribution of the free nerve end according to the spatial position of each point of the skin and the spatial position of the pore. Through the mode, the free nerve endings wrapping the hair follicles are identified, and the pain caused by the pain in the laser nursing process is effectively avoided.
Referring to fig. 4, in order to further improve the accuracy of acquiring the position of the free nerve endings in the skin, step S121 may be executed first, after the limb fixing mechanism 12 fixes the limb, the epidermal image acquisition mechanism 13 starts to continuously acquire the image of the skin surface. Step S122 may be performed to continuously compare the image of the skin surface acquired in real time with the image of the skin surface acquired in the past, and if the result of the graph comparison changes, step S123 may be performed to continuously acquire the position distribution of the free nerve endings in the skin according to the image of the skin surface. If the pattern comparison result is not changed, step S124 may be executed to use the position distribution of the free nerve endings corresponding to the previously acquired image of the skin surface that is consistent with the image of the skin surface acquired in real time as the position distribution of the free nerve endings corresponding to the image of the skin surface acquired in real time. By means of the method, the position of the free nerve ending in the skin can be accurately acquired.
Referring to fig. 5, in order to avoid the laser points from the position of the free nerve endings, the laser generating mechanism 11 generates a rectangular array composed of a plurality of laser points in the working state, the plurality of laser points are in the same plane, and each laser point can independently control the switch. The step S2 of defining the skin area to be treated, controlling the laser generating mechanism 11 to form the laser spot array in the skin according to the position distribution of the free nerve endings in the skin, and keeping the laser spot array away from the free nerve endings can also be executed first to establish a skin treatment space model according to the image of the skin area to be treated, the skin surface and the position distribution of the free nerve endings in the skin in step S211. Next, step S212 may be executed to select any point in the skin care spatial model as a skin reference point, and perform meshing division on the skin care spatial model by using the minimum distance that the laser generating mechanism 11 controls the movement of the laser point as a unit, so as to obtain a skin care rasterization spatial model. Step S213 may be executed to acquire the coordinates of the positions of the hair follicles in the skin care rasterization space model, select any hair follicle as a reference hair follicle, and use the space between the reference hair follicle and the adjacent hair follicle as a simulation test space. Step S214 may be performed to use any laser point in the laser point array as a laser reference point, and move the laser reference point from grid to grid within the grid of the simulation test space in units of the minimum distance moved by the laser point. Next, step S215 may be performed to count the intersection condition of the hair follicle of other laser points of the laser point array when the laser reference point moves in the grid of the simulation test space. Next, step S216 may be executed to select a state with the least number of intersections between the other laser points of the laser spot array and the hair follicle as a pre-execution state. Step S217 may be performed to turn off the laser spot intersected with the hair follicle in the pre-execution state, resulting in an execution state. Finally, step S218 may be executed to enable the laser generating mechanism 11 to generate laser array spots according to the execution status. By the mode, pain caused by stimulation of the laser burning small holes formed by the laser spot array to the free nerve endings is avoided.
Referring to fig. 6, in order to improve the treatment effect, i.e. improve the uniformity of the formation of the laser spot into the vesicle in the skin area to be treated, the step S2 defines the skin area to be treated, controls the laser generating mechanism 11 to form the laser spot array in the skin according to the position distribution of the free nerve endings in the skin, and keeps the laser spot array away from the free nerve endings may further include the step S221, if the plurality of positions of the reference laser spot in the simulation test space can reach a state where the number of the intersection between other laser spots of the laser spot array and the hair follicle is the minimum, i.e. a pre-execution state is reached, then the spatial distance between the laser spot and the hair follicle in each pre-execution state is respectively obtained. Step S222 may be performed next to calculate the variance and sum of the spatial distances of each laser point from each hair follicle in each pre-execution state.
