Abstract:
A biopsy forceps instrument for retrieving a tissue sample from a patient, comprising:(a) a flexible tubular member having proximal and distal ends;(b) an aspiration conduit within the flexible tubular member and adapted to provide a conduit through which the tissue sample is aspirated from the patient;(c) a distal end effector assembly coupled to said distal end of said flexible tubular member;(d) at least one flexible pull wire extending through said flexible tubular member from the proximal end to the distal end;(e) a proximal actuation handle coupled to the at least one flexible pull wire so that actuation of the handle tensions and moves the flexible pull wire thereby actuating the end effector assembly to obtain the tissue sample; and(f) a sample catch assembly coupled to said aspiration conduit and adapted to receive the sample from said aspiration conduit and retain the sample.
