Ergonomic Surgical Instrument With Detachable Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical instruments for minimal invasive surgery face challenges such as cumbersome design, lack of detachable latches, and difficulty in cleaning due to the absence of flushing connections, which hinder handling and precision during endoscopic procedures.
Innovation Solution
A surgical instrument with an ergonomic axial operating element featuring a locking mechanism and a coupling system that includes a ball-type coupling element for easy assembly and disassembly, along with a connection nipple for flushing, allowing for efficient cleaning and compatibility with various instrument shafts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operating element is made detachable for easy cleaning, then the ease of operation and maintenance is improved, but the device complexity increases due to additional coupling mechanisms
Solution Approach 1:
The instrument is divided into separable components: the operating element can be detached from the instrument shaft, and the tension/compression element can be separated from the tubular element. This segmentation enables easy cleaning of individual components while maintaining functional integrity through standardized coupling mechanisms.
Solution Approach 2:
Coupling elements serve as intermediary components that facilitate the detachable connection between the operating element and instrument shaft. These intermediaries enable easy assembly and disassembly for cleaning purposes while maintaining structural stability during operation.
2Adaptability or versatility
If the instrument shaft is made long to reach deep internal parts, then the adaptability is improved, but the stability of the instrument decreases
Solution Approach 1:
The tension and compression element is designed to be displaceably guided within the tubular element, creating a dynamic structure that can adapt to different operational requirements. This dynamic configuration allows the instrument to maintain stability while reaching deep internal parts, as the flexible element can adjust its position and tension according to the specific surgical need.
3Productivity
If the work element is made detachable for quick exchange, then the productivity is improved, but the reliability of the connection decreases
Solution Approach 1:
The work element is designed as a separable component that can be quickly exchanged at the distal end of the instrument shaft. This segmentation enables rapid更换 of different surgical tools (cutting tools, gripping devices, etc.) while maintaining secure connection through specialized coupling mechanisms that ensure reliability during operation.
