Surgical instrument with jaws and movable internal needle and method for use thereof
First Claim
1. A surgical instrument comprisinga tubular outer member having a proximal end and a distal end;
- an intermediate member having a tubular body disposed telescopically within said outer member, a proximal end and a distal end defining a pair of opposed jaws;
an inner member slidably disposed at least partly within said intermediate member and comprising a shaft and a needle on a distal end of said shaft; and
a handle coupled with at least one of said intermediate and outer members and configured to move said jaws between open and closed positions when said distal end of said outer member is moved relative to said jaws.

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.

30. A surgical instrument comprising
a tubular outer member having a proximal end and a distal end, a channel being defined through said outer member; -
an intermediate member having a body disposed at least partly within said outer member, a proximal end and a distal end having a pair of opposed jaws; an inner member slidably disposed at least partly within said channel and comprising a shaft and a needle on a distal end of said shaft; and a handle coupled with at least one of said intermediate and outer members and configured to move said jaws between open and closed positions. - View Dependent Claims (31)
