Separable Arm Support Table for Accurate Vascular Puncture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vascular puncture devices lack the ability to accurately maintain the puncture position on a target site and effectively manage the sterile and unsterile fields during the procedure.
Innovation Solution
A support table that holds the arm in place, includes an imaging unit for cross-sectional imaging, a drive unit for needle movement, and a control unit for precise puncturing, allowing separation from the main body to maintain sterile and unsterile field separation with a drape, and features a holding unit to stabilize the arm and prevent position shifts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the support table is integrated with the main body, then structural stability is improved, but maintaining sterile field separation becomes difficult
Solution Approach 1:
The device is divided into two separate components: a support table for positioning the arm and a main body for puncture operations. This segmentation allows the support table to remain in the unsterile field while the main body operates in the sterile field, connected via a barrier film that maintains field separation while enabling functional integration.
2Device complexity
If the arm is not held during puncture, then device complexity is reduced, but puncture position accuracy deteriorates
Solution Approach 1:
The arm is positioned and fixed on the support table before the puncture procedure begins. This preliminary positioning action ensures the arm remains stable during imaging and puncture, preventing position shifts and ensuring high puncture accuracy without requiring complex holding mechanisms during the actual puncture.
3Stability of the object's composition
If the support table cannot be separated from the main body, then structural stability is improved, but ease of sterilization deteriorates
Solution Approach 1:
The support table and main body are designed as separable components. The support table can be independently sterilized or disposed of, while the main body undergoes separate sterilization processes. This segmentation simplifies the sterilization workflow compared to sterilizing a fully integrated structure.
