Flexible Electrode Guidance Using Liquid Adhesion During Implantation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible electrodes are difficult to implant due to their flexibility, leading to increased tissue damage during implantation.
Innovation Solution
A method involving a guide device that engages with the flexible electrode, applies a liquid to attach a section to its surface, and guides it to a target position, using a driving device to separate and implant the electrode while a liquid spraying device ensures attachment to the guide device, minimizing tissue damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If flexible electrodes are used to reduce rejection reaction and implantation damage, then biocompatibility is improved, but ease of operation deteriorates due to difficulty in implantation
Solution Approach 1:
The patent introduces a guide device as an intermediary tool to facilitate the implantation of flexible electrodes. The guide device includes a guide needle with a liquid ejection device that sprays liquid (such as physiological saline or adhesive) onto the flexible electrode during implantation. This liquid mediation enables the flexible electrode to adhere to the guide needle, preventing detachment and ensuring accurate placement while minimizing tissue damage. The guide device acts as a mediator between the flexible electrode and the implantation site, solving the handling difficulty of flexible electrodes.
2Object-affected harmful factors
If flexible electrodes are used to reduce rejection reaction, then biocompatibility is improved, but device complexity increases due to need for guide device and liquid spraying system
Solution Approach 1:
The patent merges multiple functions into the guide device: the guide needle provides mechanical guidance, the liquid ejection device delivers liquid to the flexible electrode, and the overall structure integrates these components into a single implantation tool. This consolidation reduces the need for separate devices and simplifies the implantation process. The guide device combines guidance, adhesion promotion, and electrode placement functions, thereby reducing overall system complexity despite adding capability to handle flexible electrodes.
3Reliability
If liquid is sprayed to attach flexible electrode to guide device, then reliability of attachment is improved, but loss of substance increases due to liquid consumption
Solution Approach 1:
The patent applies liquid selectively and partially - only to specific regions of the flexible electrode that need to adhere to the guide needle, rather than coating the entire electrode. The liquid ejection device targets the proximal end or specific sections of the flexible electrode during implantation. This partial application ensures sufficient attachment reliability while minimizing liquid consumption, avoiding unnecessary waste of the liquid substance.
