摘要：A forceps apparatus is provided herein. The forcep apparatus comprises an elongated rigid tubular housing having a hollow interior comprising a bore with a longitudinal axis, the housing having a proximal end portion and a distal end portion and a length which is nearly the entire length of said forceps apparatus. The forceps apparatus further comprises a pair of forceps jaws extending beyond the distal end portion of the elongated rigid tubular housing. The forceps apparatus further comprises a manually-operable handle positioned at the proximal end portion of the housing for operating the forceps jaws, each such handle having a portion that is spaced laterally away from the longitudinal axis of the bore of the housing. The forceps apparatus further comprises a linkage extending through the bore between the handle and the forcep jaws for transmitting force between the handle and said forcep jaws during the operation of opening or closing of the forcep jaws. The forceps apparatus further comprises a cable positioned within the bore of the housing for moving the forcep jaws from a first position, wherein the forcep jaws extend in a direction which is parallel to, and generally aligned with, the longitudinal axis of the bore of the housing, to a second position, wherein the forcep jaws are positioned laterally away from the longitudinal axis of the bore of the housing, a cable end portion being permanently attached to the forcep jaws for movement therewith. The forceps apparatus further comprises a manually-operable actuator positioned at the proximal end of the housing and connected to the cable for operating the cable means. The handle and the actuator are configured for operation by hands of a user. The linkage further comprises biasing means which are rigidly supported at the distal end portion of the housing, extending from the bore of the housing for returning the forcep jaws to a position where they are aligned with the longitudinal axis of the bore of said housing.
