Surgical instrument with jaws and a movable internal blade member 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 disposed at least partly within said intermediate member, said inner member comprising a shaft and a blade on a distal end of said shaft; and
a handle coupled with at least one of said intermediate and said outer member and configured to move said pair of opposed jaws move between open and closed positions.

Abstract
An endoscopic instrument includes a forceps unit for being positioned within an anatomical cavity and inner member having a blade. 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 outer tubular member has a proximal end mounted on 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 in 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 distal end over the jaws causes the jaws to close. The inner member includes a tubular member removably disposed at least partly within the intermediate member and a blade for performing surgical functions.
