Catheter Handle Stabilizing Fork With Rotatable Side Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical device stabilizing systems require cumbersome and time-consuming manual adjustments, as traditional locking mechanisms for securing catheter handles during transcatheter procedures are inconvenient and often require axial insertion through a locking mechanism, which can be cumbersome for long catheters.
Innovation Solution
A stabilizing apparatus with a retaining arm and a stabilizing fork featuring a biasing member, allowing for secure positioning and easy adjustment of medical devices, along with a rotatable locking member for secure handling, and support tables constructed from medical device packaging for enhanced stability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional locking mechanism is used to secure the catheter handle, then the catheter handle can be secured during the procedure, but the adjustment process becomes time-consuming and cumbersome
Solution Approach 1:
The locking mechanism incorporates a rotatable locking member that can dynamically transition between locked and unlocked states. The biasing member provides continuous pressure to maintain the locked state, while rotation of the locking member allows quick transition to unlocked state for adjustments, reducing adjustment time while maintaining secure holding during procedures
Solution Approach 2:
The biasing member is pre-configured to automatically engage the locking member with the catheter handle upon insertion, providing preliminary securing action without requiring manual intervention. This preliminary action ensures the catheter handle is immediately secured when placed in the stabilizing apparatus
2Reliability
If a clamping mechanism is advanced to secure the catheter handle, then the handle can be held in position, but the mechanism requires axial insertion through an opening which is cumbersome for long catheters
Solution Approach 1:
The locking mechanism transitions from axial insertion (one-dimensional) to radial engagement (another dimension). The locking member rotates radially around the catheter handle, engaging it from the side rather than requiring axial passage through an opening. This dimensional change simplifies insertion of long catheters while maintaining secure positioning
3Adaptability or versatility
If the clamp is released and re-secured to adjust catheter handle position, then position adjustment is possible, but the process is time-consuming and inconvenient
Solution Approach 1:
The rotatable locking member enables dynamic adjustment of the catheter handle position through simple rotation. The operator can quickly rotate the locking member to an unlocked state, adjust the position, and rotate back to locked state, providing adaptability for position changes while maintaining high procedure efficiency without time-consuming clamp release and re-securing operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates precise and efficient stabilization of medical devices during procedures by reducing manual adjustment time and simplifying the handling of long catheters, while providing a secure and adjustable support system that minimizes procedural disruptions.
Implementation Method 1
A biasing member is in contact with the stabilizing fork and configured to urge the stabilizing fork toward the retaining arm
Implementation Method 2
The locking member is rotatable between a first, locked position and a second, unlocked position. When the locking member is in the locked position, the locking member has a first diameter and resists movement of the medical device relative to the locking member. When the locking member is in the unlocked position, the locking member has a second diameter, greater than the first diameter

AI summary
The present disclosure provides a stabilizing unit for a medical device. The stabilizing unit includes a retaining arm having a surface configured to abut a surface of the medical device. The stabilizing unit also includes a stabilizing fork having a slot configured to receive the medical device. A biasing member is in contact with the stabilizing fork and is configured to urge the slot of the stabilizing fork towards the retaining arm. When the medical device is placed in the slot of the stabilizing fork, the basing member urges the stabilizing fork against an adjacent surface of the medical device, and an opposing surface of the medical device against the retaining arm.
