<p>A surgical instrument (10) includes a manually engaged handle (12), and a first stem section (18) having a longitudinal axis that extends from the handle (12). A tip portion (30) of the surgical instrument (10) has a suction port (26) for applying suction to tissue, and a fluid outlet port (28) for directing fluid to tissue. A second stem section (22) is connected between the first stem section (18) and the tip portion (30), and has at least a portion which is bendable. The second stem section supports the tip portion for movement between a plurality of orientations relative to the axis, and to the first stem section. The surgical instrument (10) includes means for bending the bendable portion of the second stem (22) section to change the orientation of the tip portion (30) of the surgical instrument (10) relative to the axis, and to the first stem section (18) from a first orientation to a second orientation. The means for enabling bending movement moves the tip portion (30) through a plurality of arcuate paths which are ofdifferent lengths, and which are spaced apart from each other along the longitudinal axis.</p> |
