Home > Specialties > Punches


Definition : Instruments designed to excise or perforate a segment of material or tissue usually in the form of a disc. Punches are typically handheld, manual instruments with a movable, sharp, mechanism (e.g., a hollow tube, jaw) at the sharp working end operated by squeezing a handle (e.g., scissor-like rings, two-part hand) without rotary movement. Dedicated punches are available to take samples (e.g., skin, bone, uterus) for biopsy, for use in surgical procedures (e.g., orthopedic, middle ear), for dental device/prosthesis (e.g., rubber dam) perforation, or to make holes in devices (e.g., drainage catheters) and specific materials.
