Abstract:
A biopsy forceps instrument for retrieving a tissue sample from a patient, comprising:(a) a tubular member having proximal and distal ends; (b) an aspiration conduit 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 tubular member; (d) at least one pull wire extending through said tubular member from the proximal end to the distal end; (e) a proximal actuation handle coupled to the at least one pull wire so that actuation of the handle tensions and moves the 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, said sample catch assembly including a chamber and a sample catch member insertable into and removable from an external opening in said chamber for filtering the tissue sample from a fluid flowing through said aspiration conduit, said sample catch assembly being removable coupled to said proximal actuation handle.
