A surgical instrument includes a manually engageable handle and a first stem section having a longitudinal axis and extending from the handle. A tip portion of the surgical instrument has a suction port for applying suction to tissue and a fluid outlet port for directing fluid to tissue. A second stem section is connected between the first stem section and the tip portion 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 includes means for bending the bendable portion of the second stem section to change the orientation of the tip portion of the surgical instrument relative to the axis and to the first stem section from a first orientation to a second orientation. The means for enabling bending movement moves the tip portion through a plurality of arcuate paths which are of different lengths and which are spaced apart from each other along the longitudinal axis. |
