Integrated Ultrasonic Osteotome Bit for Surgical Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In orthopedic surgery, the frequent replacement of tool bits for ultrasonic osteotomes reduces surgical efficiency, increases operator fatigue, and disrupts the continuity of operations, leading to longer surgery times and higher risks due to the need for repeated adjustments and adaptations during procedures.
Innovation Solution
A tool bit for an ultrasonic osteotome with an integral structure combining a grinding part and a blade, featuring an umbrella-shaped cross-section, crisscrossed grooves, tooth-shaped cutting edges, and a frustum connecting portion, allowing for multiple uses without frequent replacement, enabling precise control over cutting depth and shape, and facilitating hemostasis and coagulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tool bits are replaced during surgery to achieve different cutting effects, then the versatility of the surgical tool is improved, but the surgical efficiency is reduced and operation time is prolonged
Solution Approach 1:
The tool bit integrates multiple functional structures including a cutting edge for cutting operations, a grinding part for grinding operations, and a scraping part for scraping operations. This multi-functional design allows a single tool bit to perform multiple surgical tasks that previously required different specialized tool bits, thereby improving surgical efficiency while maintaining versatility.
Solution Approach 2:
The invention combines previously separate tool bits (cutting tool bit, grinding tool bit, scraping tool bit) into a single integrated tool bit structure. The cutting edge, grinding part, and scraping part are merged into one unified tool bit that can be attached to the ultrasonic osteotome handle, eliminating the need for frequent replacements during surgery.
2Adaptability or versatility
If tool bits are frequently replaced during surgery, then different cutting effects can be achieved, but the continuity of operation is disrupted and operator fatigue increases
Solution Approach 1:
The integrated tool bit provides multiple cutting effects (cutting, grinding, scraping) through its different functional parts, allowing the surgeon to achieve various cutting effects without replacing the tool bit. This maintains operation continuity and reduces the time lost to tool bit replacements while preserving the versatility needed for different surgical requirements.
3Manufacturing precision
If multiple specialized tool bits are used for different operations, then the precision of each operation is improved, but the device complexity and workload increase
Solution Approach 1:
The invention merges multiple specialized tool bits into a single integrated tool bit that incorporates a cutting edge, grinding part, and scraping part. This reduces the number of different tool bits the surgeon needs to manage and replace, simplifying the device complexity while maintaining the precision of each operation through the specialized functional parts within the unified structure.
4Adaptability or versatility
If tool bits are replaced constantly during surgery, then different surgical needs can be met, but the risk of surgical errors increases due to repeated adaptations
Solution Approach 1:
The integrated tool bit provides surgical flexibility through its multiple functional parts (cutting edge, grinding part, scraping part) while eliminating the need for repeated tool bit replacements. This reduces the risk of surgical errors associated with frequent adaptations and re-acclimatization to different tool bits, thereby improving surgical safety while maintaining the ability to meet different surgical needs.
