Debrider Declogging Feature for Aspiration Channel Clogs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Debriders face issues with clogs in the aspiration channel during medical procedures, which can prolong procedures and potentially damage the device, as manual declogging methods are time-consuming and risky.
Innovation Solution
A debrider with a declogging feature that extends into the aspiration channel during the reciprocating motion of the inner member, automatically pushing and dislodging built-up material, thereby preventing clogs and reducing interruptions during surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual declogging method (inserting wire or stylet) is used, then clogs can be dislodged, but procedure time increases and device damage risk increases
Solution Approach 1:
The declogging feature is pre-integrated into the debrider device structure, positioned to automatically engage with the aspiration channel before clogging occurs. The feature works continuously during operation to prevent material accumulation, eliminating the need for manual intervention and procedure interruptions.
Solution Approach 2:
The debrider device performs its own declogging function through the integrated feature that automatically detects and removes clogs without requiring external tools or manual操作. The system maintains itself by using the reciprocating motion already inherent in its operation to drive the declogging action.
2Reliability
If manual declogging method (inserting wire or stylet) is used, then clogs can be dislodged, but device damage risk increases
Solution Approach 1:
The debrider device performs its own declogging function through the integrated feature that automatically detects and removes clogs without requiring external tools or manual操作. The system maintains itself by using the reciprocating motion already inherent in its operation to drive the declogging action.
Solution Approach 2:
The declogging feature acts as an intermediary element between the cutting portion and the aspiration channel, providing a controlled mechanism that safely removes clogs without the need for direct manual insertion of tools that could damage sensitive components.
3Productivity
If automatic declogging feature is added, then procedure continuity is improved, but device complexity increases
Solution Approach 1:
The declogging feature is merged with the existing debrider structure, utilizing the same reciprocating motion mechanism already present for cutting operations. By combining multiple functions into a single integrated system, the patent avoids adding separate complex mechanisms while achieving automatic declogging.
Solution Approach 2:
The reciprocating motion of the inner member serves dual purposes: performing the primary cutting function and simultaneously driving the declogging feature to clear the aspiration channel. This multi-functionality reduces the need for additional dedicated components for declogging.

AI summary
A debrider that includes an outer tubular member, and an inner tubular member located inside the outer tubular member. The inner tubular member includes an aspiration channel. The outer tubular member includes a declogging feature. The declogging feature extends from an inside distal wall of the outer tubular member in a proximal direction towards a distal wall of the inner member. The declogging feature is at least partially received into the aspiration channel through a distal opening defined in the distal end of the inner member, and is configured to push any matter located inside the aspiration channel in a proximal direction.
