Abstract

A surgical instrument includes a forceps unit for being positioned within an anatomical cavity and inner member having a needle on a distal end thereof. The forceps unit includes a housing, an outer tubular member, an intermediate 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 intermediate member has a tubular body disposed telescopically within the outer tubular member, a proximal end mounted on the housing and an integral one-piece distal end defining a pair of opposed jaws resiliently biased apart such that relative movement of the outer tubular member distally over the jaws causes the jaws to close. The inner member includes a tubular member slidably disposed at least partly within the intermediate member and carrying a needle for performing at least one of the functions of manipulating, dissecting, collecting tissue for biopsy, penetrating tissue, injecting fluids, creating suction, aspirating, irrigating, and cauterizing, or the like.
