Abstract
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.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
130 words
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.
Claim 2
Dependent Claim
130 words
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.
Claim 3
Dependent Claim
40 words
An instrument as recited in claim 1, wherein said connecting member is disposed on a shaft said shaft being mounted in said barrel to rotate about a first axis that is substantially parallel to the longitudinal axis of said barrel.
Claim 4
Dependent Claim
