Tissue removal system with retention mechanism

This invention describes a handheld surgical tool designed for minimally invasive procedures, specifically for removing tissue like in discectomy. It works by having a motor-driven inner shaft with a cutting tip that rotates inside a protective outer sheath. A unique feature is how the cutting tip is securely held within the outer sheath using small internal bumps or protrusions.

Why it matters: Manufacturing advancements since 2011, particularly in micro-machining and additive manufacturing for medical devices, could make the precise, intricate components like the tip retention mechanism more cost-effective to produce. This could simplify the fabrication of the specialized distal sheath and tip.
