Catheter Handle Stabilizing Clamp for Precise Sterile Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transvascular techniques for implanting prosthetic devices in heart valves are invasive and require cumbersome manual adjustments of catheter handles, which can be time-consuming and inconvenient during prolonged surgical procedures.
Innovation Solution
A stabilizing system comprising a base plate, carriage, and clamp mechanism that allows for secure attachment and adjustable positioning of medical devices, such as catheters, to a table, enabling precise control and easy reconfiguration without disturbing sterile barriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustments of catheter handles are performed during prolonged surgical procedures, then device positioning can be modified, but the procedure becomes time-consuming and inconvenient
Solution Approach 1:
The catheter handle is pre-attached to the stabilizing system before the surgical procedure begins, allowing the handle to be secured in the optimal position in advance. This preliminary positioning eliminates the need for repeated manual adjustments during the procedure, thereby reducing time loss and improving operational convenience.
Solution Approach 2:
A stabilizing system comprising a base plate, carriage, and clamp mechanism serves as an intermediary device between the surgeon and the catheter handle. This intermediate structure provides stable support and enables easy repositioning without requiring direct manual handling of the catheter, thus reducing time consumption and improving ease of operation.
2Measurement precision
If catheter handles are frequently adjusted during procedures, then positioning can be optimized, but sterile barriers may be disturbed
Solution Approach 1:
The stabilizing system is divided into separate modular components (base plate, carriage, clamp) that can be independently adjusted. This segmentation allows the catheter handle to be repositioned by adjusting individual components rather than manipulating the entire catheter assembly, thereby maintaining sterile barriers while achieving precise positioning.
Solution Approach 2:
The stabilizing system acts as an intermediary that decouples the sterile field from the adjustment mechanism. The carriage and clamp provide a non-sterile interface for positioning adjustments, while the catheter handle itself remains in the sterile field, thus preserving sterile barrier integrity while enabling precise positioning adjustments.
3Stability of the object's composition
If a stable attachment system is used for medical devices, then device position is maintained, but the system complexity increases
Solution Approach 1:
The stabilizing system incorporates dynamic elements including a movable carriage that can slide along the base plate and a可调 clamp mechanism. These dynamic components allow the system to adapt to different catheter lengths and configurations while maintaining stable attachment, thereby achieving position stability without excessive complexity.
Solution Approach 2:
The stabilizing system is designed with universal components that can accommodate various catheter sizes, lengths, and configurations. The carriage and clamp mechanism serve multiple functions including positioning, securing, and adjusting different types of medical devices, thus reducing overall system complexity through multi-functionality rather than requiring separate specialized components for each device type.
