[0002] Acellular dermal skin harvesting involves obtaining the dermal layer of skin for use in skin grafting or regenerative medicine. Acellular dermal skin refers to the removal of cells (such as epidermal cells and fibroblasts in the dermis) from the skin through specific treatments, while preserving its matrix and structure, so that it can be used as an implant material. It can be used in various fields of medicine. Acellular dermal skin harvesting can be performed using an acellular dermal skin harvesting device, which can be a skin harvesting knife device.

[0003] The skin-removing knife we ​​currently use consists of a blade and a handle. The operator holds the handle and brings the blade into contact with the surface of the leather to be treated, thus processing the leather. However, because the blade is fixed by the handle, it is not easy to adjust the angle of the blade on the handle, which affects the contact between the blade and the leather. This requires the operator to constantly swing their wrist to change the angle, thus affecting the effectiveness of the device.
