Biopsy forceps having a handle located at the proximal end and an end jaw assembly located at the distal end are disclosed. The handle and jaw assembly are connected by a flexible catheter tube. The handle includes a body portion and an actuator portion that controls the jaw assembly. The actuator is axially displaced relative to the handle body to open and close the pair of opposed jaws of the jaw assembly. The jaw assembly consists of a housing composed of a first and second portion, which holds the pair of opposed jaws and a distal actuator. The distal actuator is controlled by the handle actuator and in turn controls the jaws positioning. A locking mechanism is attached to the handle actuator and can be pushed into place to lock the jaws in an open position. To close the jaws, the locking mechanism can be pushed to its unlocked position and the actuator slid to its back position.
