Abstract

Disclosed is an instrument for use in a procedure to effect anastomosis of a patient'"'"'s bladder and urethra following a prostatectomy having a tube assembly, and an end effector assembly operably supported by the tube assembly. The end effector assembly includes a positioner assembly and an anchor driver assembly in operable mechanical communication with first and second rods of the tube assembly, so as to be actuable by movement of the first and the second rods with respect to a spine member.

Claims

1. An instrument for use in a procedure to effect anastomosis of a patient'"'"'s bladder and urethra following a prostatectomy, comprising:

a tube assembly, comprising a spine member, a first rod, and a second rod, wherein said rods are movable with respect to each other and to said spine member, wherein the tube assembly has a proximal portion and a distal portion; and

an end effector assembly operably supported by the distal portion of said tube assembly, further comprising;

a positioner assembly in operable mechanical communication with said first rod so as to be actuable by movement of said first rod with respect to said spine member,

an anchor driver assembly in operable mechanical communication with said second rod so as to be actuable by movement of said second rod with respect to said spine member,

an anchor releasably held by said anchor driver assembly, and

an anchor guide held by said end effector assembly through which said anchor moves when said anchor is driven proximally by actuation of said anchor driver assembly, wherein the anchor guide is configured to guide a distal end of the anchor into tissue as the anchor is initially being driven into tissue wherein the anchor guide is proximal to the anchor driver such that the anchor guide is longitudinally positioned between the anchor driver and the proximal portion of the tube assembly.

2. The instrument of claim 1 wherein said anchor guide is held by said positioner assembly.

3. The instrument of claim 2 wherein said anchor guide is releaseably held by said positioner assembly.

4. The instrument of claim 1 wherein said tube assembly further comprises a third rod, wherein said third rod is in operable mechanical communication with said end effector assembly, and wherein said third rod is movable with respect to said first rod, said second rod, and said spine.

5. The instrument of claim 1 wherein said anchor guide is releasably held by said end effector assembly.

6. The instrument of claim 1 wherein the positioner assembly comprises a movable positioner arm, wherein said anchor guide is releaseably held by said positioner arm.
