US 2019/0167291 A1 · MORCELLATOR WITH AUGER TISSUE FEEDER

Abstract

A morcellator include a housing, a knife, and a first auger. The housing defies a longitudinal axis and has an inner wall that defines a passage along the longitudinal axis. The knife is disposed about an inner wall of the housing and is secured to a distal portion of the housing. The knife extends distally from the distal portion of the housing. The first auger is disposed within the housing and has a first auger shaft and a first auger blade. The first auger shaft extends in a direction parallel to the longitudinal axis of the housing. The first auger is configured to rotate relative to the housing such that the first auger blade moves tissue proximally through the passage.
