Surgical instrument with rotatably mounted offset end effector and method of using the same
First Claim
Patent Images
1. A surgical instrument for effecting procedures on anatomical tissue comprising:
- an elongated barrel having a distal end and a proximal end;
a handle coupled to said proximal end of said barrel;
a connecting member coupled to a distal end of said barrel;
an end effector disposed on said connecting member, said end effector including two relatively movable members operable by said handle and having a longitudinal axis that is offset from a longitudinal axis of said barrel; and
wherein said connecting member is rotatable coupled to said barrel to move between a first position, in which said end effector is contained within a diametrical dimension of said barrel, and a second position, in which at least a portion of said end effector extends beyond the diametrical dimension of said barrel.

Abstract
An instrument for operating on anatomical tissue includes a barrel having at least one shaft. An end is offset from the shaft. In an insertion position, the end effector is confined within the diametrical dimension of the barrel at a distal end thereof. After insertion, the end effector can be manipulated to extend beyond the diametrical dimension of the barrel to provide a large working span in which tissue can be manipulated.

12. A surgical instrument for effecting procedures on anatomical tissue comprising:
-
an elongated barrel having a distal end and a proximal end; a handle coupled to said proximal end of said barrel; a connecting member coupled to a distal end of said barrel and extending perpendicularly from said distal end of said barrel; an end effector disposed on said connecting member, said end effector including two relatively movable members operable by said handle; and wherein said connecting member is moveably mounted to said barrel to move between a first position, in which said end effector is contained within a diametrical dimension of said barrel, and a second position, in which at least a portion of said end effector extends beyond the diametrical dimension of said barrel. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
