Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical fixing devices for brain electrode cables are inadequate, leading to deviations in electrode insertion, increased operational complexity, and discomfort for patients due to the height and friction issues of the cranial cover.
Innovation Solution
An auxiliary surgical tool featuring a cranial plug and a mounting part with protruding points, designed to securely fix the electrode cable on a cranial ring in a horizontal plane, facilitating accurate and reliable insertion and compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cranial cover is added to seal the cranial ring, then the electrode cable is fixed, but the height of the fixing device becomes too high causing discomfort and unsightly appearance
Solution Approach 1:
The patent extracts the sealing function from the traditional cranial cover and transfers it to the cranial plug itself. The cranial plug includes a plug body that directly seals the cranial ring opening, eliminating the need for a separate cranial cover layer. This reduces the overall device height while maintaining sealing reliability.
Solution Approach 2:
The patent merges the sealing function and the fixing function into a single integrated cranial plug structure. The plug body simultaneously seals the cranial ring opening and provides mounting surfaces for fixing the electrode cable, eliminating the need for separate cranial cover and ring components.
2Reliability
If the cranial cover is used to fix the electrode cable, then the cable is secured, but the cable is easily deviated and the insertion position deviates from the target
Solution Approach 1:
The patent incorporates pre-formed mounting parts with protruding points directly on the cranial plug body before the fixation process. These mounting parts are pre-positioned to ensure accurate alignment with the target insertion position, eliminating the need for post-insertion adjustments that could cause deviation.
Solution Approach 2:
The patent adds localized friction structures (such as rough surfaces or protruding points) on specific areas of the mounting parts to enhance cable fixation. This localized enhancement provides strong fixation without affecting the overall positioning accuracy of the insertion point.
3Reliability
If the traditional cranial ring and cover structure is used, then the electrode cable can be fixed, but the operation process becomes complicated and treatment effect is unsatisfactory
Solution Approach 1:
The patent segments the traditional multi-component cranial ring and cover structure into a single integrated cranial plug. This segmentation simplifies the device into one piece that performs multiple functions: sealing the cranial opening, providing mounting surfaces, and fixing the electrode cable, thereby reducing operational complexity.
Solution Approach 2:
The cranial plug is designed as a universal component that simultaneously performs sealing, mounting, and fixation functions. The plug body seals the cranial ring opening, while the integrated mounting parts with friction structures provide cable fixation, eliminating the need for separate cranial cover and ring components.
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
The tool ensures the electrode cable is firmly and accurately positioned, preventing target deviation and reducing operational complexity, while also improving patient comfort by minimizing the height of the fixing device.
Implementation Method 1
a first mounting part (40) cooperates with an upper surface of a cranial foramen plug (50) for inserting the cranial foramen plug (50) into a hole of a cranial ring
Implementation Method 2
The manufacturing material of the auxiliary tool for surgery with the above structure is engineering plastic or elastic metal material
Implementation Method 3
The brain electrode cable is clamped between the cranial cover and the cranial ring, and the brain electrode cable is fixed on the skull by the friction between the brain electrode cable and the cranial ring as well as the cranial cover
