Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Minimally invasive spinal surgery poses challenges in effectively inserting and using electrosurgical devices within the operative field between spinal vertebrae, requiring a surgical instrument that can assist in preparing the surface for implants while providing precise electrical charges for abrading and healing.
Innovation Solution
An electrosurgical device with a handle connected to an RF generator, featuring a head with multiple teeth of varying electrical charges, allowing for bipolar or monopolar configurations to facilitate precise abrading and tissue manipulation, promoting bone growth and healing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional open surgical procedures are used, then extensive operating time and post-operative recovery time are required, but minimally invasive techniques are preferred to reduce these times
Solution Approach 1:
The electrosurgical device head is segmented into multiple teeth, each capable of independent electrical charge application. This segmentation allows the device to perform multiple functions (abrading, cutting, coagulation) simultaneously across different teeth, reducing overall procedure time while maintaining ease of use through a single integrated instrument
Solution Approach 2:
The device combines multiple electrosurgical functions (monopolar and bipolar modes) in a single instrument head. The teeth can be configured to provide different electrical charges, enabling the same device to perform abrading, incision, and coagulation tasks, thereby reducing the need for multiple separate instruments and procedures
2Manufacturing precision
If multiple electrodes are provided in the operative field, then precise electrical charges can be applied for abrading and healing, but the device complexity increases
Solution Approach 1:
Multiple electrodes (teeth) are merged into a single integrated head structure that can be controlled by one handle and RF generator. The teeth are electrically connected through the head structure, allowing simultaneous control of multiple electrodes without requiring separate control mechanisms for each, thus maintaining precision while limiting complexity growth
Solution Approach 2:
The device transitions from single-point electrical contact to multi-point contact through the teeth array. This dimensional expansion allows precise electrical charge application at multiple locations simultaneously, improving manufacturing precision of tissue treatment while the integrated head design prevents proportional increase in overall device complexity
