Description
Technical Field
The invention relates to the technical field of hair follicle transplantation, in particular to a technical method for treating scars by hair follicle stem cell transplantation.
Background
The scar is the damage of physical, biological and chemical factors to human skinSoft tissueThe skin soft tissue is seriously damaged and can not be completely and normally repaired, and the fibrous tissue replaces and repairs the remained local symptoms which influence the appearance and the function. The scar brings great physical and mental pains to patients, especially scars left after burns, scalds and serious trauma.Scar hyperplasiaThe years of the period are almost overwhelming for the patient. The later atrophy period causes the patients to have complete facial disabilities and dysfunction, which causes great physical and cardiac double disorders.
Keloid scarThe surface of the swelling skin is tumor-like and hyperplastic, the surface is smooth, and the color is ruddy and brightOften with dilatationCapillary tube Blood vessel. Skin lesions extend outward from the edge and the crab legs deform. The skin injuries are different in size and shape, hard like cartilage, and have subjective symptoms of itching, pain and burning sensation. The pain is acute, and may be sensitive to nerve terminal conduction or the formation of microneuroma, even if the clothes and the like touch lightly, the pain is felt. The development is slow, most of the scar is enlarged continuously, and some scars have bright epidermis and peripheral tissues and are slightly white. There was little self-retraction and occasional malignant changes. Keloid scars are usually found on the chest, shoulders, neck, back and auricles, and are rarely found on the eyelids, palms, soles and external genitalia. Although keloid scars are relatively common, the cause of the keloid is unknown so far, which brings great difficulty to treatment. How to inhibitFiber cellThe wild proliferation of the liver, prevention of relapse and continuous growth become a difficult problem in the medical community at present. The following treatments are currently available: surgical excision, grinding,LaserRadiation, confinement, freezing, etc. Monotherapy often fails to achieve satisfactory results and tends to worsen the affected area. For example, the surgical resection has high recurrence rate, the laser and closure are often painful, and various diseases occur, irregular menstruation occurs in women, impotence and obesity occur in men, and the like. Dermabrasion, laser, freezing, etc. do not prevent recurrence, which is very troublesome for many patients and physicians. In a word, the traditional method has large wound, high treatment cost and easy formation of secondary scars, and partial patients still have unsatisfactory curative effect even if treated for multiple times. The hair follicle stem cell transplantation has the characteristics of minimally invasive, safety, durability and the like for treating scars, and has better curative effect for treating hypertrophic scars. The hair follicle stem cell can inhibitFiber cellProvides a more effective minimally invasive method for preventing the recurrence and the continuous growth of scars and treating the scars.
Disclosure of Invention
The invention aims to provide a technical method for treating scars by hair follicle stem cell transplantation. Calculating scar area and extracting hair follicle quantity by adopting a special method before operation; the individual hair follicles are extracted and separated by adopting an FUE technology, and are put into a special culture solution for culture, so that the survival rate of the hair follicles and the activity of hair follicle stem cells are improved, and the postoperative curative effect is ensured; through special preparation of a scar anesthetic and innovation of an anesthetic mode, the purposes of improving scar blood supply, softening scars and facilitating growth of hair follicle stem cells are achieved; the aims of inhibiting scar hyperplasia, softening and repairing scars, removing scars and beautifying scars are achieved through accurate planting, and the problems in the background art are solved.
In order to achieve the purpose, the invention provides the following technical scheme:
the technical method for treating scars by hair follicle stem cell transplantation comprises the following steps:
step S1, scar area calculation method and calculation of number of extracted hair follicles
Step S2, extracting hair follicles, namely extracting a follicular unit by adopting an FUE technology;
step S3, separating hair follicles, and separating individual hair follicles from the follicular units under an electron microscope;
step S4, culturing hair follicles in vitro, placing the extracted and separated individual hair follicles in a special culture solution for culturing for later use, and culturing to enhance the activity of hair follicle stem cells and promote the differentiation and proliferation of the hair follicle stem cells;
and step S5, the prescription and the anesthesia mode of the anesthetic are changed, and the preparation of the scar anesthetic and the innovation of the anesthesia mode are changed, so that the aims of improving the blood supply of scars, softening scars and facilitating the growth of hair follicle stem cells are achieved.
And step S6, transplanting the hair follicle, namely precisely planting the hair follicle in a specific area of the scar by adopting a special planting needle to promote the proliferation and differentiation of hair follicle stem cells and the formation of tissues, and achieving the purposes of inhibiting scar hyperplasia, softening and repairing the scar and removing and beautifying the scar.
Further, the specific method of step S1 is to draw the range of the scar with a marker pen, copy it on the preservative film and place it on the electrocardiographic paper for measurement, where each square grid of the electrocardiographic paper is 1 square centimeter, and calculate the number of covered squares, which is the total area of the scar. The number of follicular units to be extracted is calculated according to the area to be implanted, 5-50 follicular units per square centimeter.
Further, in step S2, the FUE technique is used to extract the hair follicle containing the hair follicle stem cells from the occipital hair or beard.
Further, in step S3, after the FUE technology is used to extract follicular units, individual follicles are separated under an electron microscope, and the follicles are separated under a state of 2-10 times amplification, so that the accuracy is up to 100%, and the follicles are prevented from being damaged during the separation process.
Further, in step S4, individual hair follicles are extracted and isolated by FUE technology, cultured in a special culture medium, and cultured at 0 to 4 ℃ for more than 60 minutes for future use.
Further, the main components of the special culture solution are 5% of glucose injection, compound glycyrrhizin injection and normal saline.
Furthermore, in step S5, the formula of anesthetic before scar anesthesia and the manner of anesthesia achieve the purposes of improving scar blood supply, softening scar, and facilitating the growth of hair follicle stem cells.
Further, in the step S5, the main components of the anesthetic are dexamethasone sodium phosphate injection, epinephrine injection, lidocaine injection, and normal saline; the scar anesthesia mode is local swelling anesthesia.
Further, in the step S6, the hair follicle planting is required to be accurate, the cultured individual hair follicles are placed into a hollow special planting needle, and then the hair follicle stem cells are directly pushed by the planting needle to form an angle of 5-80 degrees by the hair follicle as a support, so that the hair follicles are accurately planted in the preoperatively designed scar specific area. Depending on the site of implantation, 5-50 follicular units per square centimeter are achieved.
Further, the hair follicle unit contains 1-3 individual hair follicles.
Compared with the prior art, the invention has the following beneficial effects:
1. the calculation of scar area and the calculation of the number of extracted hair follicles, scars, especially hypertrophic scars and keloids, cannot be calculated in a normal manner due to the irregular bulges and edges. The method has the advantages that through a special proportional mode, the calculation is accurate, and the method is simple and feasible;
2. according to the invention, the individual hair follicles are extracted and separated by the hair follicle in-vitro culture technology and the FUE technology, the hair follicles containing hair follicle stem cells are extracted, so that the hair follicles are prevented from being damaged in the separation process, and the special culture solution is used for culturing to improve the survival rate and activity of the hair follicle stem cells;
3. the invention changes the preparation of the scar anesthetic and the anesthesia mode to improve the scar blood supply and soften the scar by innovating the prescription of the anesthetic and the anesthesia mode, and is beneficial to the growth of hair follicle stem cells;
4. the hair follicle stem cells obtained by extraction exist in the hair follicle bulge part between the sebaceous gland opening and the pileus erectus muscle attachment point. It has the characteristics of slow periodicity, strong self-renewal capacity, multi-differentiation potential, nondifferentiation, strong in vitro proliferation capacity and the like. The hair follicle stem cells belong to adult stem cells, are in a quiescent state in vivo, and show surprising proliferation capacity under the action of in vivo culture and internal environment.
