  • Publication number: 20090157111
    Abstract: An end-cutting vitrectomy probe 100 is provided that includes a hollow sleeve 102 having an opening 108 at the sleeve's distal end, and a tapered annular surface 112 disposed in the interior of the sleeve's distal end. The probe further includes a cutting member 120 disposed within the sleeve 102, and having a circumferential cutting edge 122 at its end. The cutting member 120 is moveable within the sleeve 102, such that the circumferential cutting edge 122 frictionally engages the tapered annular surface 112, to thereby cut any vitreous tissue disposed therebetween. The probe 100 may further include a drive mechanism 130 for slidably displacing the cutting member 120 within the hollow sleeve 102 in a reciprocating manner, to oscillate the cutting member 120 between engagement and disengagement with the tapered annular surface 112.
