Abstract

Systems and methods for minimally invasive discectomy procedures are described herein. In some variations, a tissue removal system may comprise a handheld housing, an outer shaft comprising a distal portion and a proximal portion coupled to the handheld housing, a distal sheath coupled to the distal portion of the outer shaft, a motor, an inner shaft coupled to the motor, where the inner shaft is located partially within the outer shaft and partially within the distal sheath, a tip portion coupled to a distal portion of the inner shaft, and an elongate member distally extending through a distal opening of the inner shaft, the elongate member having a retracted configuration and an extended configuration, where the distal sheath comprises at least one element (e.g. at least one protrusion) that engages the tip portion to couple the tip portion to the distal sheath.
