Method and device for applying basal cells extracted from human skin to repairing face sunken scars

Abstract

The invention discloses a method and device for applying basal cells extracted from human skin to repairing face sunken scars. The device comprises an extracting device; the extracting device comprises a collecting cover, a collecting cavity is arranged inside the collecting cover, liquid tubes are arranged at the two sides of the collecting cavity respectively, a rotatable roller pin column is arranged inside the collecting cavity, a notch partially exposed from the roller pin column is formed in the collecting cover, and a plurality of rows of pin bodies are evenly distributed at the surfaceof the outer circumference of the roller pin column. The method comprises the steps of 1, assembling the extracting device; 2, attaching the notch in the collecting cover to the human skin, introducing a nutrient solution or normal saline inside a liquid container into the collecting cavity through the liquid tubes, and enabling the nutrient solution or normal saline to flow on the surface of thehuman skin along with rotation of the roller pin column; 3, enabling the nutrient solution or the normal saline to flow on epidermal tissue along with rotation of the roller pin column, enabling thepin bodies to puncture basal cell particles formed by the epidermal tissue to be sucked into a negative pressure container through the negative pressure container; 4, storing the basal cell particlesinto the nutrient solution to obtain purified basal cell particles for filling a scar wound surface.

Description

technical field [0001] The invention relates to the technical field of application of basal cell technology, in particular to a method and a device for applying basal cells extracted from human skin to repair facial sunken scars. Background technique [0002] The skin is the protective barrier of the human body, which protects the human body from external natural factors and environmental pollution, and prevents excessive water loss from the body. When the skin encounters external stimuli or physical damage, the barrier is destroyed, and the physical and chemical indicators of the skin Abnormalities appear, such as dryness, dermatitis, dull skin, pigmentation, abnormal keratinization and aging of cutin, etc. When the damage is further aggravated, the skin will produce inflammatory factors and a large number of free radicals, and finally scars will be formed, which will affect the appearance. [0003] The scar is a manifestation of autologous tissue repair after skin injury. ...

AI Technical Summary

Problems solved by technology

[0005] However, there are still the following technical problems: 1) using a multi-edged knife to cut the skin vertically and horizontally will easily lead to inaccurate cutting depth, and it is easy to directly cut the dermis of the skin and damage the skin. At the same time, the skin is easy to be infected with bacteria and difficult to heal; 2) The collected skin tissue fragments need to be trimmed repeatedly to obtain adhesive skin tissue cell aggregates. The whole operation is complicated and takes a long time
