Integrated Endoscopic Tool for Polyp Debriding and Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopic tools for polyp removal are inefficient and time-consuming, requiring separate devices for cutting and retrieving polyps, leading to sample bias and incomplete screening due to the inability to handle multiple polyps effectively during colonoscopy.
Innovation Solution
An integrated endoscopic tool with a debriding component and sample retrieval conduit that allows for simultaneous cutting and retrieval of polyps through a single instrument, utilizing a turbine assembly for polyp debridement and suction conduit for sample collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate cutting tool and sample retrieving tool are used, then polyp removal can be performed, but procedure time increases and efficiency decreases
Solution Approach 1:
The patent combines a cutting tool and sample retrieving tool into a single integrated endoscopic device. The cutting component (e.g., snare or knife) and sample retrieval component (e.g., forceps or basket) are merged into one instrument that can perform both functions sequentially or simultaneously through a single working channel, eliminating the need to exchange tools during the procedure.
Solution Approach 2:
The endoscopic tool is designed with multi-functionality, allowing it to serve as both a cutting instrument and a sample retrieval instrument. The device can be actuated to cut polyps and then immediately actuated again to retrieve the same or additional polyps without removing the tool from the patient's body, thereby reducing procedure time and increasing efficiency.
2Productivity
If only largest polyps are sampled, then procedure time is reduced, but sample bias occurs and screening completeness decreases
Solution Approach 1:
The integrated tool enables continuous action by allowing the operator to cut and retrieve multiple polyps in sequence without interruption or tool exchange. The operator can systematically examine and remove polyps of various sizes during a single continuous procedure, ensuring complete sampling while maintaining efficient workflow through the merged functionality of the tool.
3Ease of operation
If multiple separate devices are used for cutting and retrieval, then polyp handling capability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple separate endoscopic instruments into a single integrated device that houses both cutting and sample retrieval capabilities. This consolidation reduces the number of instruments the operator must manage while providing enhanced polyp handling capability through the coordinated action of the integrated components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances precision and efficiency in polyp removal, enabling rapid collection and analysis of multiple polyps without the need for multiple devices, reducing procedure time and improving screening completeness.
Implementation Method 1
The debriding component may include a turbine assembly and a cutting tool. The turbine assembly may be rotated to drive the cutting tool.
Implementation Method 2
The turbine assembly may be rotated to drive the cutting tool. The cutting tool may be rotated or reciprocating, or may be stationary, while the turbine assembly rotates to drive the cutting tool.
Implementation Method 3
a sample retrieval conduit disposed within the housing for retrieving debrided material that is debrided by the debriding component
Data Source
AI summary
An improved endoscopic tool easily and efficiently obtains samples of multiple polyps from a patient by debriding one or more polyps and retrieving the debrided polyps without having to alternate between using a separate cutting tool and a separate sample retrieving tool and may be used with an endoscope.
