实验步骤举例：

    Raise an intradermal wheal with anesthetic agent. Stabilize the skin with the thumb and forefinger, stretching it slightly perpendicular to the normal skin tension lines; this will produce an oval rather than round defect, facilitating closure.

    Place the punch perpendicular to the skin and apply firm and constant downward pressure with a circular twisting motion. Removal of the punch to "check the progress" 首ld be avoided as this may result in a ragged wound and a shredded biopsy sample. A definite "give" occurs when the punch reaches the subcutaneous fat, indicating that a full-thickness cut has been made. Remove the punch and apply downward finger pressure at the sides of the wound to pop up the core. Completely elevate the core with gentle use of forceps or a needle tip and excise it at its base with small tissue scissors. The pressure applied through forceps to elevate the core 首ld be gentle to minimize the destruction and distortion of tissue in the biopsy sample. After finishing the harvest of the tissue, prepare the biopsy site for closure。
