ABSTRACT:
A surgical instrument includes a forceps unit for being positioned within an anatomical cavity. The forceps unit includes a housing, an outer tubular member, an intermediate tubular member, and a handle mechanism coupled with at least one of the intermediate and outer tubular members for creating relative movement between the intermediate and outer tubular members. The outer tubular member has a proximal end mounted by the housing and terminates distally at a distal end. The intermediate member has a tubular body disposed telescopically within the outer tubular member, a proximal end mounted by the housing and a pair of opposed jaws disposed on a distal end of the tubular body resiliently biased apart such that relative movement of the outer tubular member distal end over the jaws causes the jaws to close. A channel or passage is defined through the instrument to permit an inner member having an end effector to be inserted therethrough.
