Abstract
An improved biopsy forceps for retrieving a tissue sample from an internal organ is provided with flexible resilient means for ejecting a tissue sample from the cups after the sample is retrieved from the internal organ. The ejector means can comprise a leaf spring extending between the cups and biased in a convex distal direction so that it springs outward when the cups are fully opened, ejecting the tissue sample. An actuating wire has a spring latch for moving the leaf spring to the ejection position and for returning it to a position inside the cups. The wire disengages from the cups so that it can extend distally no eject the sample. A latch mechanism at the proximal end of the wire selectively prevents actuation.
