Minimally invasive biopsy device

摘要

A minimally invasive biopsy device (10) includes a cylindrical retractor (12) and a cylindrical cutting tool (14) slidingly engaged within the cylindrical retractor (12). The cylindrical retractor (12) is adapted for insertion in an incision (43) above a lesion (61) to be excised, and separates the walls of the incision (43) to provide access to the tissue to be excised. The cylindrical cutting tool (12) has a cutting means (21) which makes a cylindrical incision around the tissue to be excised. The tissue can then be accurately and quickly removed.
