Removable Insert for Surgical Handpiece Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical handpieces face challenges in user-friendly cleaning and sterilization, particularly in accessing areas around the cutting tool connection and aspiration channel, which can lead to inadequate cleaning before sterilization.
Innovation Solution
A surgical handpiece design featuring a removable insert with a groove and tabs for easy aspiration of fluid and tissue, a valve for controlling aspiration, and an access port with a cover for cleaning and sterilization access, allowing for the removal and replacement of the insert to facilitate thorough cleaning and sterilization of internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handpiece uses a fixed integrated design, then structural integrity is maintained, but cleaning and sterilization access is difficult
Solution Approach 1:
The handpiece is divided into modular components including a removable insert with cutting tool, a valve assembly, and an access port with cover. This segmentation allows each component to be independently accessed, cleaned, and sterilized while maintaining overall structural integrity when assembled.
Solution Approach 2:
The insert containing the cutting tool and aspiration channel is designed to be completely removed from the handpiece body. This extraction enables thorough cleaning of internal channels and surfaces that would otherwise be inaccessible, while the main handpiece structure remains intact for reuse.
2Reliability
If the handpiece has sealed aspiration channels, then fluid containment is improved, but access for cleaning is reduced
Solution Approach 1:
The design incorporates preliminary disassembly steps where the insert and valve are removed before cleaning begins. This preliminary action exposes the sealed aspiration channels and internal surfaces, allowing thorough cleaning while maintaining fluid containment integrity during normal operation when components are assembled.
Solution Approach 2:
The removable insert acts as an intermediary component that provides access to the sealed aspiration channels. When removed, it allows cleaning solutions to reach internal surfaces; when installed, it restores the sealed fluid containment system.
3Reliability
If the cutting tool connection area is sealed, then sterile barrier is maintained, but cleaning accessibility is reduced
Solution Approach 1:
The cutting tool connection area is integrated into the removable insert. By extracting the entire insert from the handpiece body, complete access to the connection area is achieved, allowing thorough cleaning and sterilization while maintaining the sterile barrier function when the insert is properly reinstalled.
Solution Approach 2:
The insert is designed as a disposable or reusable component that can be completely removed, cleaned, sterilized, and replaced. This approach ensures the cutting tool connection area maintains sterile barrier integrity during use while allowing complete cleaning access when the insert is removed or replaced.
