Multi-Functional Surgical Accessory for Hard and Soft Tissue Resection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical tool systems require multiple accessories for effectively removing both hard and soft tissues during endoscopic procedures, which increases procedural time, equipment costs, and complexity.
Innovation Solution
A multi-functional surgical accessory with a cutting head featuring distinct tissue-treating areas for both hard and soft tissue removal, incorporating abrading regions and windowed configurations to facilitate efficient cutting and resection of various tissue types with a single tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple surgical accessories are used to effectively remove both hard and soft tissues, then tissue removal effectiveness is improved, but device complexity and equipment costs increase
Solution Approach 1:
The patent combines hard tissue removal features (bur-like cutting surfaces) and soft tissue removal features (shaver-like cutting edges) into a single surgical accessory. The cutting head includes both types of cutting elements on its periphery, allowing one accessory to perform functions that previously required multiple separate tools, thereby reducing device complexity while maintaining tissue removal effectiveness
Solution Approach 2:
The surgical accessory is designed with multi-functional capabilities to handle both hard and soft tissue removal. The cutting head incorporates diverse cutting features including bur-like surfaces for hard tissue and sharp cutting edges for soft tissue, making a single accessory universal for different tissue types and reducing the need for multiple specialized tools
2Manufacturing precision
If multiple surgical accessories are used for different tissue types, then cutting precision is improved, but procedural time increases
Solution Approach 1:
The accessory provides universal cutting precision for both hard and soft tissues through its multi-functional cutting head design. By integrating both bur-like and shaver-like cutting features in one accessory, surgeons can maintain precise cutting performance across different tissue types without the time loss associated with switching between multiple specialized accessories
3Adaptability or versatility
If multiple surgical accessories are used for different tissue removal tasks, then versatility is improved, but equipment costs increase
Solution Approach 1:
The patent merges the functionality of multiple accessories into one by combining hard tissue removal capabilities (bur-like cutting surfaces) and soft tissue removal capabilities (shaver-like cutting edges) on a single cutting head. This consolidation maintains comprehensive tissue type coverage while reducing equipment costs by eliminating the need to purchase and store multiple separate accessories
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
The multi-functional surgical accessory reduces the need for multiple tools, enhances procedural efficiency, minimizes trauma to the patient, and lowers equipment costs by enabling effective removal of both hard and soft tissues with a single device.
Implementation Method 1
The cutting head may include first and second tissue-treating areas spaced from one another along an outer peripheral area... The first tissue-treating area may include an abrading region configured for removing a first tissue type
Implementation Method 2
The second tissue-treating area may include a windowed configuration... configured for removing a second tissue type having a second hardness less than the first hardness
