Tube-Based Compliant Mechanism Biopsy Tool ID: 2015-051

A novel biopsy tool designed to improve sample retrieval efficiency and safety during minimally invasive procedures.

Technology Overview

This technology outlines the development of a new kind of biopsy tool that employs a tube-based compliant mechanism inspired by origami designs. Unlike traditional needle biopsy instruments, which often suffer from poor sample retention and can cause significant tissue damage due to multiple insertions, this innovative tool aims to enhance sample retention while minimizing tissue damage. It incorporates a unique grabbing mechanism that ensures reliability across different insertion angles, making it a promising solution for minimally invasive surgical procedures.

Key Advantages

• Improved sample retention compared to existing needle biopsy instruments
• Reduced tissue damage due to fewer required insertions
• Cost-effective and simpler manufacturing process thanks to the monolithic construction from a round tube
• Increased reliability across various insertion angles due to the innovative grabbing mechanism

Problems Addressed

• Poor sample retention in needle biopsy procedures
• Increased risk of tissue damage from multiple biopsy insertions
• Complexity and high cost of manufacturing traditional biopsy instruments
