Abstract
Abstract The instrument with vacuum extraction system and cutters working together extracts tissue samples from body cavities. It comprises two tubes sliding one inside the other (2,3), the outer one having an opening (4) near the end and being closed by a light source (5). The inner one has a cutting edge (6) at the end inside the outer one, and a handle (7) at the other end, which is closed by a transparent component (8) and incorporates a suction pipe (9) leading to the interior of the tube. The light source can be a battery-powered lamp or a light-conductor, or a fluorescent component.
