Blades, Trephine, Biopsy
Definition : Trephine blades designed to cut and remove circular sections of anatomic tissues for histological examination (i.e., biopsy). These devices typically consist of a hollow cylindrical blade having circular saw-like edges, a shaft, and a proximal end that is appropriate for connection to the rotary handpiece. The biopsy sample occupies the hollow center of the trephine from which it can be removed after trephine extraction. Dedicated trephine biopsy blades, both reusable and single-use, are available for skin biopsy (either standard or excision biopsy), bone biopsy, and intraosseous biopsy (e.g., bone marrow biopsy).
