A biopsy forceps instrument for retrieving a tissue sample from a patient has a flexible tube, an aspiration conduit through which the tissue sample can be aspirated from the patient, a distal end effector assembly coupled to a distal end of the flexible tube and at least one pull wire extending through said tube. A proximal actuation handle of the instrument includes a stationary member coupled to the flexible tube on the pull wire, and a movable member movable relative to the stationary member and coupled to the other of the flexible tube or the pull wire, wherein movement of the movable member relative to said stationary member moves the pull wire and actuates the distal end effector assembly so as to obtain the tissue sample. A chamber arrangement is coupled to the aspiration conduit for receiving the sample from the aspiration conduit and for retaining the sample, the chamber arrangement being coupled to the proximal actuation handle and having a plurality of chambers for discretely storing a plurality of tissue samples. |
