Manipulator apparatus
First Claim
1. A surgical apparatus for manipulating body tissue, which comprises:
- a handle member;
a generally elongated member connected to said handle member and extending distally therefrom, said elongated member having a longitudinal axis and including proximal and distal end portions, said distal end portion pivotally connected to said proximal end portion about a pivot pin and being pivotal about said pivot pin relative to said longitudinal axis;
an expandable member mounted to said distal end portion of said elongated member and movable upon pivotal movement of said distal end portion; and
a fluid dispenser at least partially disposed within said handle member and being in fluid communication with said expandable member for selectively incrementally dispensing fluid into said expandable member to selectively incrementally inflate said expandable member.

Abstract
A surgical apparatus for manipulating bodily tissue includes a handle member, an elongated member connected to the handle member and extending distally therefrom, a fluid expandable member supported at a distal end portion of the elongated member and a fluid dispensing mechanism in fluid communication with the expandable member for selectively incrementally dispensing inflation fluid into the expandable member to selectively incrementally inflate the expandable member. The distal end portion of the elongated member is adapted to articulate relative to a longitudinal axis defined by the remaining portion of the elongated member such that the expandable member is pivotal therewith. A control mechanism is provided to selectively control articulation of the distal end portion of the elongated member.

9. A surgical apparatus for manipulating bodily tissue, which comprises:
-
a frame member including a chamber for accommodating a supply of fluid and a plunger axially movable within said chamber for dispensing the fluid; an elongated member connected to said frame member and including a lumen in communication with said chamber of said frame member, said elongated member generally defining a longitudinal axis, at least a portion of said elongated member being arcuate in configuration in a longitudinal direction; an expandable member mounted to a distal end portion of said elongated member and in communication with said lumen; and plunger advancing means for selectively incrementally advancing said plunger within said chamber to dispense fluid through said lumen and into said expandable member to selectively incrementally inflate said expandable member. - View Dependent Claims (10)
