Solution Overview
Problem
Current arthroscopic surgical devices face challenges in efficiently tunneling through hard tissue due to limitations in cross-sectional footprint and operational orientations, which affect insertion and tunneling capabilities.
Innovation Solution
An arthroscopic surgical device featuring a flexible arcuate tunneling needle driver and a rotatable bone engagement element with multiple operative orientations, including a trans-incision insertion cross-sectional footprint and a larger tunneling cross-sectional footprint, equipped with a ratchet handle, bone engagement pin with tapered screw threading, and a suture mounting assembly for efficient tissue tunneling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device uses a single cross-sectional footprint design, then the device structure is simple, but the device cannot efficiently transition between insertion and tunneling operations
Solution Approach 1:
The device incorporates a rotatable bone engagement element that can transition between multiple operative orientations (insertion orientation and tunneling orientation), allowing the device to dynamically adapt its cross-sectional footprint based on the operational phase without requiring multiple separate devices
Solution Approach 2:
The single device structure integrates both insertion and tunneling functions through the rotatable bone engagement element, enabling one device to perform multiple operations (insertion through incision and subsequent tunneling through hard tissue) that would traditionally require different specialized instruments
2Productivity
If the device uses a small cross-sectional footprint for insertion, then the insertion capability is good, but the tunneling capability is insufficient
Solution Approach 1:
The rotatable bone engagement element enables the device to switch between a compact insertion footprint and an expanded tunneling footprint, optimizing the cross-sectional dimensions for each specific operational phase
Solution Approach 2:
The device transitions from a two-dimensional cross-sectional footprint during insertion to a three-dimensional operational configuration during tunneling, utilizing the rotational degree of freedom to expand the effective working area while maintaining minimal insertion profile
