Trephines, Biopsy, Skin

Definition : Biopsy trephines designed to cut and remove circular sections of skin tissue intended for laboratory examination and/or test with minimal sample and surrounding tissue damage. These trephines are typically handheld, reusable, metal instruments consisting of hollow cylinders with a circular-saw-like working edge attached to a rotary manual or powered surgical handpiece; disposable (i.e., single use) trephines with ribbed plastic handles attached to stainless steel hollow cylinder blades are also available. Skin biopsy trephines with similar characteristics and/or with wider diameter cylindrical blades are also used for excisional biopsy, a procedure mainly intended to excise neoplasms from the skin.
