Colpotomizer Cup Locking Mechanism for Uterine Manipulators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current uterine manipulators face challenges in securely positioning the colpotomizer cup during medical procedures, leading to potential misalignment and instability, which can obstruct visual access and require additional adjustments.
Innovation Solution
A uterine manipulator design featuring a colpotomizer cup with a sleeve and locking member that engages a locking feature on the handle, providing a stable and intuitive locking mechanism with audible and tactile feedback, allowing for quick and secure positioning without visual obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a colpotomizer cup is used without a locking mechanism, then the device structure is simpler, but the cup becomes unstable and may become misaligned during use
Solution Approach 1:
The locking member is designed to automatically engage with the locking feature on the handle when the colpotomizer cup is properly positioned, providing self-locking functionality without requiring additional manual operations or complex mechanisms. The spring arms naturally deflect and snap into the locking feature, ensuring reliable positioning while maintaining structural simplicity.
2Ease of operation
If the colpotomizer cup placement requires visual monitoring, then positioning precision is improved, but the procedure time increases and complexity increases
Solution Approach 1:
The locking mechanism provides tactile and audible feedback when the colpotomizer cup is correctly positioned and locked to the handle. This feedback mechanism allows the operator to confirm proper placement without continuous visual monitoring, reducing procedure time and complexity while maintaining positioning accuracy.
3Measurement precision
If additional adjustments are made during the procedure, then positioning precision is improved, but the procedure time increases
Solution Approach 1:
The locking mechanism is designed to secure the colpotomizer cup in the correct position during the initial placement phase, eliminating the need for subsequent adjustments. By ensuring accurate positioning upfront through the self-locking feature, the procedure progresses more efficiently without requiring additional corrective actions.
