Abstract
A jaw assembly for an endoscopic bioptome includes a pair of opposed end effectors having resilient arms formed from a super-elastic metal. The distal ends of the resilient arms terminate in end effector jaw cups which are also preferably formed from super-elastic metal, while the proximal portions of the resilient arms include angled portions which urge the jaw cups away from each other. The jaw cups are brought together into a biting action by a cylinder having a sharp distal edge which moves relative to and over he arms of the end effectors. As the resilient arms are formed from a super-elastic metal, they exhibit very high resiliency and durability even after numerous uses.
