Description

Technical Field

[0002] Traditional skin harvesting on the market generally uses an electric skin harvester to harvest 10cm*10cm or other large areas of skin tissue, or skin flaps. The above methods have been used in clinical surgery for many years. However, large-area skin harvesting is painful for patients, and it is like robbing Peter to pay Paul. Large scars are easily formed in the harvested area. The skin harvesting devices on the market do not have spectral probes and cannot perform colorimetric recognition of skin color. In this way, it is easy to transplant dark-colored tissue to a lighter-skinned area, or vice versa, resulting in uneven color in the grafted area, and prone to dot- or flaky "spots", especially on the face, affecting the patient's appearance and quality of life. The skin harvesting devices on the market do not have measurement and imaging optical systems, and cannot evaluate the length, width and area of ​​scars, and cannot provide physicians with high-definition image assistance devices.
