Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slitter tools for removing insertion catheters during electrode line implantations are unreliable in fixing the electrode line, prone to slipping, and can cause damage due to manual fixation methods that are not adaptable to different diameters and require strenuous operator effort.
Innovation Solution
A slitter tool with clamping forceps that have changeable legs and a pushbutton-actuated spreading element, allowing for secure fixation and easy handling by automatically opening the clamping mechanism, ensuring reliable grip and minimizing electrode line damage across various diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual fixation using finger pressure on clamping forceps is used, then the electrode line can be fixed, but the fixation is unreliable and slipping can occur
Solution Approach 1:
The clamping forceps are designed with a spring mechanism that automatically maintains clamping pressure on the electrode line without requiring continuous manual force. The spring-loaded structure provides self-sustaining fixation that returns to the clamped position automatically, eliminating the need for constant operator intervention and ensuring reliable fixation throughout the procedure.
Solution Approach 2:
The clamping forceps incorporate a dynamic spring mechanism that automatically adjusts and maintains optimal clamping pressure. The spring-loaded design allows the forceps to dynamically adapt to the electrode line while providing consistent fixation force without requiring manual pressure application, thereby improving reliability while simplifying operation.
2Reliability
If constant finger pressure on a pushbutton is applied to maintain fixation, then the electrode line is secured, but the operator experiences strain and may make incorrect movements
Solution Approach 1:
The pushbutton mechanism is connected to a spring-loaded system that automatically maintains the clamped position without requiring continuous operator pressure. Once the button is pressed to initiate clamping, the spring mechanism sustains the fixation automatically, freeing the operator from maintaining constant finger pressure and eliminating operator strain while preserving secure fixation.
Solution Approach 2:
The fixation mechanism uses periodic spring action to maintain clamping pressure automatically. The spring-loaded system provides continuous, automatic reinforcement of the clamped position through its elastic recovery, eliminating the need for sustained manual pressure application and thereby reducing operator strain while maintaining reliable fixation security.
3Adaptability or versatility
If clamping forceps with fixed legs are used, then the structure is simple, but the device cannot adapt to different electrode line diameters
Solution Approach 1:
The clamping forceps incorporate movable legs that can adjust their position dynamically to accommodate different electrode line diameters. The spring-loaded mechanism allows the legs to move independently while maintaining clamping contact, providing adaptability to various sizes without requiring complex adjustment mechanisms or multiple tool configurations.
Solution Approach 2:
The clamping forceps are designed with segmented, movable legs that can independently adjust to fit different electrode line diameters. This segmentation allows each leg to adapt to the specific dimensions of the electrode line being clamped, providing versatility across different sizes while maintaining a relatively simple overall structure through the use of basic spring-loaded joints.
4Reliability
If the electrode line is manually held during slitting, then fixation can be maintained, but the electrode line may buckle or be damaged
Solution Approach 1:
The spring-loaded clamping forceps automatically maintain stable fixation on the electrode line throughout the slitting procedure without requiring manual holding. The self-sustaining spring mechanism provides consistent, evenly distributed clamping pressure that secures the electrode line firmly in place, preventing buckling and damage while eliminating the need for manual support that could cause harm.
Solution Approach 2:
The clamping forceps are designed with spring-loaded legs that provide beforehand cushioning by automatically adapting to the electrode line diameter and providing gentle, evenly distributed clamping pressure. This pre-adjusted spring mechanism cushions the electrode line against excessive force or uneven pressure during clamping, preventing buckling and damage while maintaining reliable fixation stability throughout the procedure.

Function Achieved in This Case
The tool provides a reliable, slip-proof fixation of electrode lines with simplified handling, reducing the risk of damage and accommodating different diameters, while allowing for easy reinsertion and minimizing tilting during the slitting process.
Implementation Method 1
The legs (2) are shaped so that they can be moved between a clamped position and an open position by the action of spring elements (9a, 9b).

AI summary
Slitting tool for slitting open a catheter shaft, including a housing, a blade fastened on the housing, a pushbutton, which is mounted so it is displaceable on the housing, and clamping forceps, which are mounted so they are movable on the housing. The clamping forceps are partially located inside the housing, and include two clamping legs, which are connected to one another at their base located in the housing and have a mutual pre-tension, and which cause the fixation of an electrode line on their periphery located outside the housing, such that the pushbutton, which is mounted so that it is displaceable, and the clamping forceps, which are mounted so that they are movable, act together with one another in such a manner that an actuation of the pushbutton causes an opening of the fixation in the periphery of the clamping forceps.
